Further, these expressions do not exclude the case where α includes other elements.

[0024] The following embodiments can be combined with each other, provided that no technical inconsistencies arise.

[0025] <First Embodiment> The following describes one embodiment of the present invention with reference to the drawings. Figure 1 is a diagram showing the configuration of a deodorizing apparatus according to one embodiment of the present invention.

[0026] [Overall structure] The deodorizing treatment device 100 is connected to a facility 200 that generates odorous gas. Facility 200 generates odorous gas containing high concentrations of ammonia and other substances, exhibiting a strong malodor. Specific examples include composting facilities and wastewater treatment facilities, but any facility that generates malodors may be used. The odorous gas discharged from facility 200 is supplied to the deodorizing treatment device 100 via a gas pipe 151.

[0027] The gas pipe 151 is made of a material that has pressure resistance and corrosion resistance, such as metal or polyvinyl chloride, and is configured in the form of a pipe, tube, or hose through which gas can pass. As will be described later, a blower 152 to increase the airflow, gas flow resistance regulators 153 and 155 to control the airflow, and a cooling device 154 to cool the odorous gas are provided in the middle of the gas pipe 151.

[0028] [Configuration of the processing equipment] The deodorization treatment device 100 is equipped with a treatment facility consisting of a deodorization tank 110, a water spraying device 120, a drainage tank 130, and a water storage tank 140. Of these, the odor of the odorous gas is removed by microorganisms fixed to a microbial carrier filled in the deodorization tank 110.

[0029] [Configuration of the deodorizing tank] The deodorizing tank 110 is, for example, a rectangular container with a height of 8 meters and a width and length of 9 meters x 12 meters, respectively. The deodorizing tank is made of a material with high pressure resistance and corrosion resistance, such as metal, hard resin, or reinforced concrete.

[0030] At the bottom of the deodorizing tank 110, there is an opening for taking in odorous gas connected to the gas pipe 151, and a space is provided that allows the odorous gas to spread throughout the entire space in a plan view. It is desirable to secure this space by laying down structural elements or pallets made of structural elements about 20 to 40 cm in height. Furthermore, it is desirable that a mesh sheet or plate be installed on top of the pallets to prevent the microbial carrier from flowing out into the drainage tank 130.

[0031] [Microorganisms and microbial carriers] The deodorizing tank 110 is filled with a microbial carrier. Ammonia-degrading microorganisms and hydrogen sulfide-degrading microorganisms are immobilized on the microbial carrier. Ammonia-degrading microorganisms are microorganisms that decompose ammonia dissolved in water or convert it into other substances. A typical example of ammonia-degrading bacteria is nitrifying bacteria. Nitrifying bacteria nitrify dissolved ammonia, converting it into nitrite and nitrate. Here, nitrification refers to the oxidative decomposition of ammonia. Examples of nitrifying bacteria include ammonia-oxidizing bacteria and nitrite-oxidizing bacteria; the former converts ammonia into nitrite, and the latter converts nitrite into nitrate. In this way, the ammonia in the odorous gas is decomposed and the odor is removed. Hydrogen sulfide-degrading microorganisms are microorganisms that decompose hydrogen sulfide dissolved in water or convert it into other substances. A typical example of hydrogen sulfide-degrading bacteria is sulfur bacteria. Sulfur bacteria decompose dissolved hydrogen sulfide into water and sulfur. The gas from which the odor has been removed in this way is discharged outdoors from the top of the deodorizing tank 110.

[0032] While porous glass is preferable for the microbial carrier, it is not particularly limited as long as it can adequately support the microorganisms. For example, in addition to glass, it may be made of synthetic resin foam (expanded propylene), wood, ceramic, etc., and its shape may be spherical, irregular, honeycomb, cylindrical, etc.

[0033] As an example of a microbial carrier, porous glass particles with a diameter of several millimeters to several centimeters are desirable. The pores of the glass particles should ideally be several micrometers to several millimeters in size, with a surface area of ​​several square meters to tens of square meters per gram. Ammonia-degrading microorganisms and hydrogen sulfide-degrading microorganisms can inhabit these pores.

[0034] Odor gas is drawn in from the bottom of the deodorizing tank 110, and as the odor gas slowly rises, the odor is removed by microorganisms living on the microbial carrier. The odor-free gas is then discharged outdoors from the top of the deodorizing tank 110.

[0035] [Configuration of the sprinkler system] The sprinkler system 120 is located above the deodorizing tank 110. It consists of a water supply pipe with numerous sprinkler nozzles 121. This water supply pipe draws treated water from the storage tank 140 using a pump 122. The treated water is water, but it may contain various chemicals such as phosphoric acid to adjust the pH and the environment for microbial activity. The treated water contains liquid-based air bubbles generated by the aeration system 142, which will be described later.

[0036] The treated water sprayed from the numerous spray nozzles 121 of the watering device 120 is used to promote the growth and activity of microorganisms inhabiting the microbial carrier. The treated water that descends through the deodorization tank flows into the storage tank 140 via the drainage tank 130 and drainage recovery pipe 141, where it is stored again. In this way, the treated water is circulated and used within the deodorization treatment device 100.

[0037] For the growth of microorganisms, it is desirable to vary the amount and frequency of treated water sprayed by the watering device 120 according to the temperature and other factors. Furthermore, since microorganisms living on the microbial carrier generate heat when active, the treated water plays a role in cooling the microorganisms by absorbing that heat. Therefore, for example, in the summer when temperatures are high, it is desirable to increase the number of watering sessions and the amount of water sprayed each time. Specifically, it is desirable to increase the watering frequency, for example, from spraying for about 5 minutes per hour in winter to spraying for about 5 minutes every 30 minutes in summer.

[0038] [Drainage tank configuration] The drainage tank 130 is a tank for recovering treated water that has flowed down from the deodorization tank 110. A drainage drain is provided in the center or at one end of the bottom of the drainage tank 130, and the bottom of the drainage tank 130 is sloped at approximately 2 degrees toward the drainage drain. However, it is not limited to this, and the bottom of the drainage tank 130 only needs to be sloped at 1 degree or more toward the drainage drain. The drainage drain is provided with a basket to receive the microbial carrier that has passed through the mesh. The treated water discharged from the drainage drain flows into the water storage tank 140 via the drainage recovery pipe 141.

[0039] [Water storage tank configuration] The water storage tank 140 stores the recovered treated water. The water storage tank 140 is equipped with an aeration device 142 to ensure that the treated water contains a high concentration of air, particularly oxygen. The aeration device 142 may be, for example, a microbubble generator. In this case, the microbubble generator may generate oxygen-containing microbubbles in the treated water. The treated water stored in the water storage tank 140 is supplied to the sprinkler system by a pump 122. The water storage tank 140 may also be equipped with a water distribution pipe via a drain valve 143, a water supply pipe via a water supply valve 144, and a spraying device 145. Both the drain valve 143 and the water supply valve 144 are solenoid valves, and their operation is controlled by a control device 160, which will be described later, along with the pump 122. The spraying device 145's operation is controlled by a control device 160, which will be described later. Figure 1 shows a deodorizing treatment device 100 consisting of one deodorizing tank 110, one watering device 120, one drainage tank 130, and one water storage tank 140. However, the device is not limited to this configuration, and the treatment device may also consist of two deodorizing tanks 110 connected together, in which case two water storage tanks 140 may be provided. The two water storage tanks 140 may exchange water with each other.

[0040] [Configuration of the supply route for odorous gases] Odor gas discharged from facility 200 is supplied to deodorization treatment device 100 via gas pipe 151. Along the gas pipe 151, there is a blower 152 that supplies odor gas from facility 200 to the gas pipe 151, gas flow resistance regulators 153 and 155 that control the airflow rate, and a cooling device 154 that cools the odor gas. Between facility 200 and blower 152, a demister for dehumidification and dust removal may be further provided. The demister may be made of, for example, a sponge-like material that separates foreign matter such as liquid particles and dust contained in the odor gas.

[0041] The blower 152 increases the flow velocity of the odorous gas discharged from the facility 200. It generates negative pressure on the intake side (left in the diagram) and positive pressure on the exhaust side (right in the diagram). This blower is inverter-controlled, allowing for continuous control of its rotational speed. Airflow and air pressure can be controlled by controlling the rotational speed. Operation and rotational speed are controlled by the control device 160.

[0042] The odorous gas emitted from facility 200 is relatively hot. Depending on the ambient temperature and the facility's operating conditions, it can exceed 70°C. Passing through gas pipe 151 provides some cooling effect, but this is insufficient, so the odorous gas is cooled by cooling device 154. As a result, the odorous gas at the output side of cooling device 154 is below 40°C. The cooling device can be configured in various ways, such as a radiator with numerous water pipes through which cooling water circulates, or a configuration that directly cools the odorous gas by spraying water inside a cavity. The cooling capacity can be adjusted by changing the circulation speed of the cooling water in the former case, or by changing the amount of water sprayed in the latter case. The operation is controlled by control device 160.

[0043] The gas flow resistance regulators 153 and 155 are provided on the input and output sides of the cooling device 154, respectively, but may be provided on either side. The gas flow resistance regulators 153 and 155 may be, for example, gas dampers. The gas flow resistance regulators 153 and 155 can reduce the flow rate of the odorous gas by adjusting the resistance of the odorous gas flow through the rotation of movable valves. The gas flow resistance regulators 153 and 155 can also cool and dilute the odorous gas by opening and closing an air inlet connected to the outside air. The opening and closing angle of the movable valve (adjustment of flow resistance) and the opening and closing of the air inlet are performed by a motor, and this is controlled by the control device 160.

[0044] [Sensor group] The deodorizing treatment device 100 is equipped with sensors 171, 172, 173, 174, 175, 176, 177, 178, and 179. These sensors measure various values, but sensors 171, 172, 173, and 174 measure one or more of the following: the flow rate of odorous gas, ammonia concentration, temperature, or dust content, or the pressure inside the pipes. Sensor 175 measures one or more of the flow rate, ammonia concentration, or temperature of the gas discharged outdoors. Sensor 176 measures one or more of the following: the pressure, ammonia concentration, or pressure inside the deodorizing tank 110. Sensor 177 measures the flow rate of treated water in the wastewater recovery pipe 141, and sensor 178 measures one or more of the following: pH, temperature, ammonia concentration, NO concentration, NO2 concentration, dissolved oxygen concentration, electrical conductivity, and water level of the treated water stored in the water storage tank 140. Sensor 179 measures the flow rate of treated water in the water supply pipe between the pump 122 and the watering nozzle 121. The measurements from these sensors are then transmitted to the control device 160. Furthermore, the drainage drain of the drainage tank 130 is provided with an outflow microbial carrier cage (not shown) to receive the microbial carriers that have passed through the mesh, and a sensor may be provided to measure the weight of the outflow microbial carrier cage or the amount of outflow microbial carriers in the cage.

[0045] Due to the nature of the deodorization process, sensors 171, 172, 173, 174, 175, 176, 177, 178, and 179 do not need to continuously measure; for example, measurements can be taken once an hour, once every six hours, or once a day. However, it is desirable to increase the measurement frequency as an urgent situation (alert) approaches. For example, this could occur if sensor 176 detects that the temperature of the deodorization tank 110 is rising, if sensor 175 detects that the ammonia concentration of the exhaust gas is above a predetermined level, if the water level in the water storage tank 140 falls below a predetermined level, if sensor 174 detects that the temperature of the odorous gas supplied to the deodorization tank 110 is above a predetermined level, or if sensor 179 detects clogging of the watering nozzle 121. It could also occur if the weight of the microbial carrier cage or the amount of microbial carrier inside the cage is detected to be above a predetermined value. In such cases, the system is configured to increase the measurement frequency when the first threshold is exceeded, and to issue an alarm when the second threshold is exceeded.

[0046] [Control device] The deodorizing treatment device 100 is equipped with a control device 160. The control device 160 is a microcontroller and includes a CPU and memory device (not shown).

[0047] The measured values ​​transmitted from sensors 171, 172, 173, 174, 175, 176, 177, 178, and 179 are temporarily stored in the memory of the control device 160. The control device 160 then controls one or more of the following: the airflow rate of the blower 152, the water flow rate or water flow frequency of the watering device 120 (controlling the pumping timing and amount of water pumped by the pump 122, and controlling the amount of water used by the watering nozzles 121, which are operated by a solenoid valve (not shown)), the cooling capacity of the cooling device 154, the opening degrees of the gas flow resistance regulators 153 and 155, the amount of air bubbles generated in the liquid by the aeration device 142, the water supply and drainage to the water storage tank 140 (water supply and drainage are performed by opening and closing the drain valve 143 and the water supply valve 144), the mist spraying to the water storage tank 140, and the temperature of the deodorizing tank 110 (the temperature is raised by operating a heater (not shown)). The dotted arrows in the figure indicate the transmission paths for measured values ​​(data) from sensors 171, 172, 173, 174, 175, 176, 177, 178, and 179 to the control device 160, and the transmission paths for control signals from the control device 160 to the blower 152, watering device 120, cooling device 154, gas flow resistance regulators 153 and 155, aeration device 142, drain valve 143 and water supply valve 144, and spray device 145, respectively (only a portion is shown).

[0048] The control device 160 includes a communication device 161. Measurement values ​​transmitted from sensors 171, 172, 173, 174, 175, 176, 177, 178, and 179 are first stored in the memory of the control device 160, and then the communication device 161 transfers these stored measurement values ​​(data) to a remote server. The communication device 161 communicates wirelessly with a base station, for example, using a 4G network or a 5G network.

[0049] [Various control modes] Based on the measurements transmitted from sensors 171, 172, 173, 174, 175, 176, 177, 178, and 179, the control device 160 operates a program that implements the following algorithm and operates in the corresponding control mode to control one or more of the following: the airflow rate of the blower 152, the water flow rate or frequency of the water sprayer 120, the cooling capacity of the cooling device 154, the opening degrees of the gas flow resistance regulators 153 and 155, the amount of air bubbles generated in the liquid by the aeration device 142, the water supply and drainage to the water storage tank 140, the mist spraying to the water storage tank 140, and the temperature of the deodorizing tank 110. These will be described in detail below.

[0050] [Control Mode 1 (Temperature-based control 1)] The activity of nitrifying bacteria in the deodorizing tank 110 decreases when the temperature of the supplied odor gas exceeds 40°C. Therefore, appropriate temperature control is necessary. First, the temperature of the odor gas at the point where it is supplied to the deodorizing tank 110 is measured by the temperature sensor in sensor 174. If this temperature exceeds a certain margin from the control temperature of 40°C, for example, 35°C, the inverter of the blower 152 is controlled to reduce the airflow rate (for example, by lowering the rotation speed). If the temperature at the odor gas supply port of the deodorizing tank 110 does not decrease sufficiently even after reducing the airflow rate, the flow resistance of the gas flow resistance regulator 155 is then increased (the valve is rotated from the open side to the closed side). The gas flow resistance regulator 155 can be operated more precisely by comparing the pressure measurements of the pressure sensors included in sensors 173 and 174 between its input and output sides. If the airflow rate is reduced solely by controlling the blower 152, it may be overwhelmed by the flow resistance of the cooling device 154. However, by controlling the amount of odor gas supplied to the odor gas supply port in combination with the gas flow resistance regulator 155, the operation of the cooling device 154 will not be stopped. In this way, even if the temperature of the odor gas supplied from the facility 200 changes according to the outside air and the conditions of the facility 200, the deodorization treatment device can always be operated with high efficiency.

[0051] [Control Mode 2 (Temperature-based control 2)] First, the temperature of the odor gas at the point where it is supplied to the deodorization tank 110 is measured by the temperature sensor in the sensor 174. If the temperature exceeds, for example, 35°C, the capacity of the cooling device 154 is increased. For example, if the cooling device 154 is a radiator type with many water pipes circulating cooling water, the capacity can be improved by increasing the circulation speed of the cooling water. If it is a type that directly cools the odor gas by spraying water inside a cavity, the capacity can be improved by increasing the amount of water sprayed. It is desirable to use this control mode 2 in conjunction with control mode 1. In this way, even if the temperature of the odor gas supplied from the facility 200 changes according to the outside air and the conditions of the facility 200, it is always possible to operate the deodorization treatment device with high efficiency.

[0052] [Control Mode 3 (Control based on ammonia concentration of odorous gas)] The nitrifying bacteria in the deodorizing tank 110 reduce their decomposition efficiency when the ammonia concentration of the supplied odor gas exceeds a certain level. Therefore, the ammonia concentration in the odor gas at the point where the odor gas is supplied to the deodorizing tank 110 is measured by the ammonia concentration sensor in the sensor 174. The ammonia concentration sensor can be a laser sensor that measures the concentration by the degree of laser absorption, or a high-frequency sensor that measures the concentration by supplying high frequency between electrodes and measuring the degree of resonance. If the ammonia concentration in the odor gas at the point where the odor gas is supplied to the deodorizing tank 110 exceeds the appropriate concentration that the deodorizing tank 110 can process, the inverter of the blower 152 is controlled to reduce the airflow rate. If the ammonia concentration does not decrease sufficiently even after reducing the airflow rate, the flow resistance of the gas flow resistance regulator 155 is then increased. In this way, even if the ammonia concentration of the odor gas supplied from the facility 200 increases, the deodorizing treatment device can always be operated with high efficiency.

[0053] [Control Mode 4 (Control based on exhaust ammonia concentration 1)] If the ammonia concentration of the gas discharged from the deodorizing tank 110 is above a certain level, it means that the deodorizing tank 110 is operating under a high load that exceeds its capacity. Therefore, the ammonia concentration of the gas discharged from the deodorizing tank 110 is measured by the ammonia concentration sensor in the sensor 175. If the ammonia concentration in the exhaust gas exceeds environmental standards or other set values, the inverter of the blower 152 is controlled to reduce the airflow rate. If the ammonia concentration in the exhaust gas does not decrease sufficiently even after reducing the airflow rate, the flow resistance of the gas flow resistance regulator 155 is then increased. In this way, even if the ammonia concentration of the odorous gas supplied from the facility 200 increases, it is always possible to operate the deodorizing treatment device with high efficiency.

[0054] [Control Mode 5 (Control based on exhaust ammonia concentration 2)] As mentioned above, if the ammonia concentration of the gas discharged from the deodorizing tank 110 is above a certain level, it means that the deodorizing tank 110 is operating under a high load that exceeds its capacity. One possible cause of this is a decrease in the activity of microorganisms fixed to the microbial carrier in the deodorizing tank 110. The reason for this decrease in microbial activity may be the temperature mentioned above. Therefore, the temperature is lowered by using control mode 1 or 2, or a combination thereof. In this way, it is possible to prevent the deodorizing treatment device from becoming overloaded.

[0055] [Control Mode 6 (Control based on exhaust ammonia concentration 3)] As described above, if the ammonia concentration of the gas discharged from the deodorizing tank 110 is above a certain level, it means that the deodorizing tank 110 is operating under a high load that exceeds its capacity. One possible reason for this is that there is insufficient treated water sprayed onto the microbial carrier in the deodorizing tank 110, resulting in a decrease in the activity of the fixed microorganisms. Therefore, if the ammonia concentration sensor reading of the sensor 175 is above a predetermined value, the pump 122 can be controlled to increase the amount of water sprayed or increase the spraying frequency, and the number of nozzles used can be increased by operating a solenoid valve (not shown) to further increase the amount of water sprayed. In this way, it is possible to prevent the deodorizing treatment device from becoming overloaded.

[0056] [Control Mode 7 (Control based on exhaust ammonia concentration 3)] As mentioned above, if the ammonia concentration of the gas discharged from the deodorizing tank 110 is above a certain level, it means that the deodorizing tank 110 is operating under a high load that exceeds its capacity. One possible reason for this is that the oxygen concentration in the treated water sprayed onto the microbial carrier in the deodorizing tank 110 is insufficient, resulting in a decrease in the activity of the fixed microorganisms. Therefore, if the ammonia concentration sensor of sensor 175 measures above a predetermined value, the aeration device 142 can be activated to supply more oxygen to the treated water. In this way, it is possible to prevent the deodorizing treatment device from becoming overloaded.

[0057] [Control Mode 8 (Control based on temperature inside the deodorizing tank 1)] The decrease in microbial activity may be due to the temperature inside the deodorizing tank 110 as described above. If the temperature sensor 176 reads a predetermined value, for example 50°C, the pump 122 can be controlled to increase the water flow rate or the water flow frequency, and the number of nozzles used can be increased by operating a solenoid valve (not shown) to further increase the water flow rate. As the water flow rate increases, cooling progresses. In this way, the deodorizing treatment device can be prevented from becoming overloaded.

[0058] [Control Mode 9 (Control based on temperature inside the deodorizing tank 2)] As mentioned above, the decrease in microbial activity may be due to the temperature inside the deodorizing tank 110. If the temperature reading from the sensor 176 exceeds a predetermined value, for example, 50°C, the temperature is reduced by control mode 1 or 2, or a combination thereof. In this way, the deodorizing device can be prevented from becoming overloaded.

[0059] [Control Mode 10 (Control based on measurement results of treated water)] Within the deodorizing treatment device 100, treated water is circulated and reused. When the thermometer on sensor 178 indicates a temperature above a predetermined level, the water supply valve 144 is opened to supply water to the water tank, or mist is sprayed into the water tank by the spraying device 145. The spraying of mist by the spraying device 145 also contributes to the removal of dust in the water tank. When the water level gauge on sensor 178 indicates a decrease in the water level of the water tank 140, the water supply valve 144 is opened to replenish the water. When the water level gauge on sensor 178 indicates a rise in the water level of the water tank 140, the drain valve 143 is opened to drain the water. If the pH sensor on sensor 178 indicates a value outside the predetermined range, or if the dissolved ammonia sensor, NO sensor, NO2 sensor, electrical conductivity sensor, or dissolved oxygen concentration sensor indicates a value outside the predetermined range, the drain valve 143 is opened to drain the water and the water supply valve 144 is opened to supply new water. In this way, it is possible to prevent the treated water from becoming unsuitable for microbial activity and to prevent limescale buildup in the pipes, which can cause malfunctions.

[0060] [Remote information gathering system] Figure 2 shows a deodorizing treatment device according to one embodiment of the present invention connected via a communication network. Multiple combinations of a facility 200 that emits odorous gas and a deodorizing treatment device 100 are provided in multiple regions (facility 200-1 and deodorizing treatment device 100-1 are provided in one region, facility 200-2 and deodorizing treatment device 100-2 are provided in another region, and the number of regions may be even greater). A communication device 161 provided in the deodorizing treatment device 100 (communication device 161-1 is provided in deodorizing treatment device 100-1 in one region, and communication device 161-2 is provided in deodorizing treatment device 100-2 in another region) wirelessly communicates with base stations 311 and 312 using, for example, a 4G network or a 5G network. Base stations 311 and 312 are connected to a server 301 and a user terminal 303 via the internet 302, and further to a wireless user terminal 304 via another base station 313.

[0061] Server 301 receives measurement values ​​(data) transmitted from sensors 171, 172, 173, 174, 175, 176, 177, 178, and 179 from communication devices 161-1 and 161-2, and stores them in its storage device. The frequency of acquiring measurement values ​​(data) into Server 301 may be, for example, once an hour, once a day, once a week, or according to the instructions of user terminals 303 and 304. The acquired data may be from a single measurement or from multiple measurements (for example, 24 data points measured once an hour are transmitted once a day).

[0062] A web server runs on server 301, and the measurement values ​​acquired by this web server are displayed on the browser screens of user terminals 303 and 304. It is desirable to display graphs so that the hourly or daily trends can be understood. In addition, various measurement values ​​for each region may be displayed on a single web page, or various measurement values ​​for multiple regions may be overlaid on a single graph. In this way, it becomes possible to centrally manage deodorizing treatment equipment in multiple regions and to compare and examine their operating status.

[0063] [Communication that does not go through a server] In the example above, the measured values ​​collected via server 301 were viewed on user terminals 303 and 304. However, the software installed on user terminals 303 and 304 (which is an applet (app) in the case of a smartphone) may directly receive the measured values ​​(data) from communication devices 161-1 and 161-2.

[0064] [Alerts due to abnormal values] If the measured values ​​(data) transmitted from sensors 171, 172, 173, 174, 175, 176, 177, 178, and 179 show abnormal values ​​or other situations requiring urgent action (alert), the control device 160 may be configured to push the data to the server 301 at its own initiative. In this case, emergency information (alert information) may also be sent directly to user terminals 303 and 304 using SMS or email protocols. The system administrator operating user terminals 303 and 304 can immediately rush to the site and take action. Situations requiring urgent action include, for example, when sensor 176 detects a rapid increase in the temperature of the deodorizing tank 110; when sensor 175 detects that the ammonia concentration of the exhaust gas is above a predetermined level; when sensor 178 detects that the water level of the water storage tank 140 has fallen below a predetermined level and the water level does not recover even after opening the water supply valve 144 and supplying water; when sensor 174 detects that the temperature of the odor gas supplied to the deodorizing tank 110 is above a predetermined temperature; or when sensor 174 detects that the weight of the spilled microbial carrier cage or the amount of microbial carrier inside the cage is above a predetermined value.

[0065] [Maintenance Alert] A dust amount sensor included in any of sensors 171, 172, 173, or 174 may be configured to periodically measure the amount of dust in the odor gas, and if the accumulated amount exceeds a predetermined value, the server 301 may be configured to generate a maintenance alert on user terminals 303 and 304.

[0066] [Control of deodorizing equipment from a remote location] By using the above system, the operating status of the deodorizing treatment devices 100-1 and 100-2 can be managed on user terminals 303 and 304. User terminals 303 and 304 may be configured to send instructions to communication devices 161-1 and 161-2 via server 301 or directly, in response to user instructions, to control one or more of the following: the airflow rate of the blower 152, the water flow rate or frequency of the water sprayer 120, the cooling capacity of the cooling device 154, the opening degree of the gas flow resistance regulators 153 and 155, the amount of air bubbles generated in the liquid by the aeration device 142, the water supply and drainage to the water storage tank 140, and the temperature of the deodorizing tank 110.

[0067] <Second Embodiment> Figure 3 shows the configuration of a deodorizing apparatus according to one embodiment of the present invention. The configuration of the deodorizing apparatus according to the second embodiment is the same as the configuration of the deodorizing apparatus according to the first embodiment, except that it has a second blower instead of a cooling device, and further includes a third blower and a demister. The explanation of the sameness as the first embodiment will be omitted, and the differences from the configuration of the deodorizing apparatus according to the first embodiment will be explained here.

[0068] [Overall structure] The deodorizing treatment device 100a is connected to the facility 200 that generates odorous gas. The odorous gas discharged from facility 200 is supplied to the deodorizing treatment device 100 via a gas pipe 151. As will be described later, a demister 156 and a first blower 152 for increasing the airflow are installed in the middle of the gas pipe 151. The demister 156 filters the odorous gas discharged from facility 200 to dehumidify and remove dust. The condensation (drainage) discharged by the demister 156 flows into the water storage tank 140 via a drainage recovery pipe 157. Between the demister 156 and the first blower 152, there is a pipe 181 connected to which a second blower 182 is installed, which takes in outside air and dilutes the odorous gas discharged from facility 200.

[0069] [Configuration of the processing equipment] The deodorization treatment device 100 is equipped with a treatment facility consisting of a deodorization tank 110, a watering device 120, a drainage tank 130, and a water storage tank 140. Of these, the odor of the odorous gas is removed by microorganisms fixed to a microbial carrier filled in the deodorization tank 110. The configuration of the deodorization tank 110, watering device 120, and drainage tank 130 in this embodiment is the same as the configuration of the deodorization tank 110, watering device 120, and drainage tank 130 in the first embodiment, so a description is omitted.

[0070] Odor gas is drawn in from the bottom of the deodorizing tank 110, and as the odor gas slowly rises, the odor is removed by microorganisms living on the microbial carrier. The odor-free gas is then discharged outdoors from the top of the deodorizing tank 110. An intake port for outside air, connected to piping 185, is provided at the top of the deodorizing tank 110, creating a space to further dilute the odor-free gas with outside air. A third blower 186 for supplying outside air is connected to piping 185.

[0071] The watering device 120 is installed above the deodorization tank 110. It consists of a water supply pipe with numerous watering nozzles 121. This water supply pipe draws treated water from the storage tank 140 using a pump 122. The treated water that descends from the deodorization tank flows into the storage tank 140 via the drainage tank 130 and the drainage recovery pipe 141, where it is stored again. In this way, the treated water is circulated and used within the deodorization treatment device 100.

[0072] The drainage tank 130 is a tank for recovering treated water that has flowed down from the deodorization tank 110. The treated water discharged from the drainage drain flows into the storage tank 140 via the drainage recovery pipe 141.

[0073] The water storage tank 140 stores the recovered treated water. The water storage tank 140 is equipped with an aeration device 142 to ensure that the treated water contains a high concentration of air, particularly oxygen. The treated water stored in the water storage tank 140 is supplied to the sprinkler system via a water supply valve 146 by a pump 122. The water storage tank 140 may also be equipped with a water distribution pipe via a pump 147 and a drain valve 143, a water supply pipe via a water supply valve 144, and a spraying device 145. These drain valve 143, water supply valve 144, and water supply valve 146 are all solenoid valves and their operation is controlled by a control device 160, which will be described later, along with pumps 122 and 147. The spraying device 145's operation is controlled by a control device 160, which will be described later. In Figure 3, the deodorizing treatment device 100a is shown as a treatment facility consisting of one deodorizing tank 110, one watering device 120, one drainage tank 130, and one water storage tank 140. However, the treatment facility is not limited to this configuration, and may also consist of two deodorizing tanks 110 connected together, in which case two water storage tanks 140 may be provided. The two water storage tanks 140 may exchange water with each other.

[0074] [Configuration of the supply route for odorous gases] Odor gas discharged from facility 200 is supplied to deodorization treatment device 100a via gas pipe 151. A demister 156 for dehumidification and dust removal and a first blower 152 for supplying odor gas from facility 200 to gas pipe 151 are installed in the middle of gas pipe 151. Between the demister 156 and the first blower 152, a pipe 181 is connected that contains a second blower 182 for supplying outside air and an intake valve 183.

[0075] The first blower 152 increases the flow velocity of the odorous gas discharged from the facility 200. The first blower 152 is inverter-controlled, allowing for continuous control of its rotational speed. By controlling the rotational speed, the airflow volume and air pressure can be controlled. The operation and rotational speed of the first blower 152 are controlled by the control device 160.

[0076] The odorous gas discharged from facility 200 is relatively hot. The odorous gas discharged from facility 200 is diluted and cooled by adding outside air supplied by the second blower 182. The second blower 182 is inverter controlled, allowing for continuous control of its rotational speed. By controlling the rotational speed, the airflow rate and air pressure can be controlled. The operation and rotational speed of the second blower 182 are controlled by the control device 160. An intake valve 183 may also be provided between the second blower 182 and the gas pipe 151. The intake valve 183 is an electromagnetic valve, and its operation is controlled by the control device 160. Preferably, the amount of outside air supplied by the second blower 182 is the same as or less than the amount of odorous gas discharged from facility 200. As a result, the odorous gas at the input side of the first blower 152 is 40°C or lower.

[0077] The third blower 186 further dilutes the odor-free gas by adding outside air. The third blower 186 is inverter-controlled, allowing for continuous control of its rotational speed. By controlling the rotational speed, the airflow and air pressure can be controlled. The operation and rotational speed of the third blower 186 are controlled by the control device 160. An intake valve 187 may be provided between the third blower 186 and the top of the deodorizing tank 110. The intake valve 187 is a solenoid valve, and its operation is controlled by the control device 160.

[0078] [Sensor group] The deodorizing treatment device 100 is equipped with sensors 170, 171, 175, 176, 177, 178, and 179. These sensors measure various values, but sensors 170 and 171 measure one or more of the following: the flow rate of odorous gas, ammonia concentration, temperature, humidity, or dust content, or the pressure inside the pipes. Sensor 175 measures one or more of the flow rate, ammonia concentration, or temperature of the gas discharged outdoors. Sensor 176 measures one or more of the following: the pressure, ammonia concentration, temperature, or pressure inside the deodorizing tank 110. Sensor 177 measures the flow rate of treated water in the wastewater recovery pipe 141, and sensor 178 measures one or more of the following: pH, temperature, ammonia concentration, NO concentration, NO2 concentration, dissolved oxygen concentration, electrical conductivity, and water level of the treated water stored in the water storage tank 140. Sensor 179 measures the flow rate of treated water in the water supply pipe between the pump 122 and the watering nozzle 121. The measured values ​​from these sensors are then transmitted to the control device 160.

[0079] [Control device] The deodorizing treatment device 100a is equipped with a control device 160. The control device 160 is a microcontroller and includes a CPU and memory device (not shown).

[0080] The measured values ​​transmitted from sensors 170, 171, 175, 176, 177, 178, and 179 are temporarily stored in the memory device of the control device 160. The control device 160 controls one or more of the following: the airflow rate of the first blower 152, the airflow rate of the second blower 182, the airflow rate of the third blower 186, the amount of water sprayed or the frequency of water spraying of the water spraying device 120 (controlling the pumping timing and amount of water pumped by the pump 122 and the water supply valve 146, and controlling the amount of water spraying nozzles 121 used by a solenoid valve (not shown)), the amount of air bubbles generated in the liquid by the aeration device 142, the supply and drainage of water to the water storage tank 140 (controlling the drainage timing and amount of water drained by the pump 147, and supplying and draining water by opening and closing the drain valve 143 and the water supply valve 144), the spraying of mist to the water storage tank 140, and the temperature of the deodorizing tank 110 (raising the temperature by operating a heater (not shown)). The dotted arrows in the figure indicate the transmission paths for measured values ​​(data) from sensors 170, 171, 175, 176, 177, 178, and 179 to the control device 160, and the transmission paths for control signals from the control device 160 to the first blower 152, the second blower 182, the third blower 186, the watering device 120, the aeration device 142, the pump 147, the drain valve 143 and the water supply valve 144, and the spraying device 145, respectively (only a portion is shown).

[0081] The control device 160 includes a communication device 161. Measurement values ​​transmitted from sensors 170, 171, 175, 176, 177, 178, and 179 are first stored in the memory of the control device 160, and then the communication device 161 transfers these stored measurement values ​​(data) to a remote server. The communication device 161 communicates wirelessly with a base station, for example, using a 4G network or a 5G network.

[0082] [Various control modes] Based on the measured values ​​transmitted from sensors 170, 171, 175, 176, 177, 178, and 179, the control device 160 operates in the corresponding control mode by running a program that implements the following algorithm, thereby controlling one or more of the following: the airflow rate of the first blower 152, the airflow rate of the second blower 182, the airflow rate of the third blower 186, the water spraying rate or frequency of the water spraying device 120, the amount of air bubbles generated in the liquid by the aeration device 142, the water supply and drainage to the water storage tank 140, the mist spraying to the water storage tank 140, and the temperature of the deodorizing tank 110. The following description will omit explanations that are the same as in the first embodiment, and will detail the differences from the control modes according to the first embodiment.

[0083] [Control Mode 1 (Temperature-based control)] The activity of nitrifying bacteria in the deodorizing tank 110 decreases when the temperature of the supplied odor gas exceeds 40°C. Therefore, appropriate temperature control is necessary. First, the temperature of the odor gas at the point where it is supplied to the deodorizing tank 110 is measured by the temperature sensor in sensor 171. If this temperature exceeds a certain margin from the control temperature of 40°C, for example, 35°C, the inverter of the first blower 152 is controlled to reduce the airflow rate (for example, by lowering the rotation speed). If the temperature at the odor gas supply port of the deodorizing tank 110 does not decrease sufficiently even after reducing the airflow rate, the inverter of the second blower 182 is controlled to increase the airflow rate of outside air (for example, by increasing the rotation speed). The airflow rate of outside air can be controlled more precisely by the intake valve 183. In this way, even if the temperature of the odor gas supplied from the facility 200 changes according to the conditions of the outside air and the facility 200, the deodorizing treatment device can always be operated with high efficiency.

[0084] [Control Mode 2 (Control based on ammonia concentration of odor gas)] The nitrifying bacteria in the deodorizing tank 110 reduce their decomposition efficiency when the ammonia concentration of the supplied odor gas exceeds a certain level. Therefore, the ammonia concentration in the odor gas discharged from the facility 200 is measured by the ammonia concentration sensor in sensor 170. The ammonia concentration in the odor gas at the point where the odor gas is supplied to the deodorizing tank 110 is measured by the ammonia concentration sensor in sensor 171. If the ammonia concentration in the odor gas discharged from the facility 200 exceeds the appropriate concentration that can be processed by the deodorizing tank 110, the inverter of the first blower 152 is controlled to reduce the airflow rate. If the ammonia concentration does not decrease sufficiently even after reducing the airflow rate, the inverter of the second blower 182 is then controlled to increase the airflow rate of outside air. The airflow rate of outside air can be controlled more precisely by the intake valve 183. In this way, even if the ammonia concentration of the odor gas supplied from the facility 200 increases, the deodorizing treatment device can always be operated with high efficiency.

[0085] [Control Mode 3 (Control based on exhaust ammonia concentration 1)] If the ammonia concentration of the gas discharged from the deodorizing tank 110 is above a certain level, it means that the deodorizing tank 110 is operating under a high load that exceeds its capacity. Therefore, the ammonia concentration of the gas discharged from the deodorizing tank 110 is measured by the ammonia concentration sensor in the sensor 175. If the ammonia concentration in the exhaust gas exceeds environmental standards or other set values, the inverter of the first blower 152 is controlled to reduce the airflow rate. If the ammonia concentration in the exhaust gas does not decrease sufficiently even after reducing the airflow rate, the inverter of the second blower 182 is controlled to increase the airflow rate of outside air. In this way, even if the ammonia concentration of the odor gas supplied from the facility 200 increases, it is always possible to operate the deodorizing treatment device with high efficiency.

[0086] [Control Mode 4 (Control based on exhaust ammonia concentration 2)] As described above, if the ammonia concentration of the gas discharged from the deodorizing tank 110 is above a certain level, it means that the deodorizing tank 110 is operating under a high load that exceeds its capacity. Therefore, the ammonia concentration of the gas discharged from the deodorizing tank 110 is measured by the ammonia concentration sensor in the sensor 175. If the ammonia concentration in the exhaust gas exceeds the environmental standard or other set value, the inverter of the third blower 186 is controlled to increase the amount of outside air being blown in. By diluting the gas discharged from the deodorizing tank 110 with outside air, the ammonia concentration in the exhaust gas can be controlled to meet the environmental standard or other set value. The ammonia concentration in the gas discharged from the deodorizing tank 110 may be, for example, 50 ppm. If the environmental standard is 5 ppm, the environmental standard can be met by diluting the gas discharged from the deodorizing tank 110 tenfold.

[0087] [Control Mode 5 (Control based on exhaust ammonia concentration 3)] As described above, if the ammonia concentration of the gas discharged from the deodorizing tank 110 is above a certain level, it means that the deodorizing tank 110 is operating under a high load that exceeds its capacity. One possible reason for this is that there is insufficient treated water sprayed onto the microbial carrier in the deodorizing tank 110, resulting in a decrease in the activity of the fixed microorganisms. Therefore, if the ammonia concentration sensor reading of sensor 175 is above a predetermined value, the pump 122 can be controlled to increase the amount of water sprayed or increase the spraying frequency, and the number of nozzles used can be increased by operating a solenoid valve (not shown) to further increase the amount of water sprayed. The amount of treated water sprayed can be controlled more precisely by the water supply valve 146. In this way, it is possible to prevent the deodorizing treatment device from becoming overloaded.

[0088] [Control Mode 6 (Control based on measurement results of treated water)] Within the deodorizing treatment device 100, treated water is circulated and reused. When the thermometer on the sensor 178 indicates a temperature above a predetermined level, the water supply valve 144 is opened to supply water to the water tank, or mist is sprayed into the water tank by the spraying device 145. The spraying of mist by the spraying device 145 also contributes to the removal of dust in the water tank. The temperature of the treated water is preferably, for example, between 10°C and 35°C, and more preferably between 10°C and 30°C. When the water level gauge on the sensor 178 indicates a decrease in the water level of the water tank 140, the water supply valve 144 is opened to replenish the water. When the water level gauge on the sensor 178 indicates a rise in the water level of the water tank 140, the drain valve 143 is opened to drain the water. The amount of treated water drained can be further increased or the draining frequency increased by controlling the pump 147. If the pH sensor of sensor 178 shows a value outside the predetermined range, or if the dissolved ammonia sensor, NO sensor, NO2 sensor, electrical conductivity sensor, or dissolved oxygen concentration sensor shows a value outside the predetermined range, the drain valve 143 is opened to drain the water and the water supply valve 144 is opened to supply fresh water. The amount of treated water drained can be further increased by controlling the pump 147 to increase the drainage rate or increase the drainage frequency. The pH of the treated water is preferably between 6.5 and 8.5, and more preferably between 6.5 and 8.3. In this way, it is possible to prevent the treated water from becoming unsuitable for microbial activity and to prevent limescale buildup in the piping that causes malfunctions.

[0089] [Remote information gathering system] Figure 4 shows a deodorizing treatment device according to one embodiment of the present invention connected via a communication network. Multiple combinations of a facility 200 that emits odorous gas and a deodorizing treatment device 100 are provided in multiple areas (facility 200-1 and deodorizing treatment device 100-1 are provided in one area, and facility 200-2 and deodorizing treatment device 100-2 are provided in another area. The number of areas may be even greater). A sensor 190 provided outside the deodorizing treatment device 100 (sensor 190-1 is provided in deodorizing treatment device 100-1 in one area, and sensor 190-2 is provided in deodorizing treatment device 100-2 in another area) measures, for example, one or more of the odor of the external environment (not limited to ammonia), wind direction, atmospheric pressure, humidity, and temperature. Preferably, the sensor 190 is provided in four different directions around the deodorizing treatment device 100. The communication device 161 provided in the deodorizing treatment device 100 (communication device 161-1 is provided in the deodorizing treatment device 100-1 in one region, and communication device 161-2 is provided in the deodorizing treatment device 100-2 in another region) communicates wirelessly with base stations 311 and 312, for example, using a 4G network or a 5G network.

[0090] Neighborhood facilities 400 are provided around the facility 200 that emits odorous gas and the deodorizing treatment device 100 (facility 400-1 is provided in one area, facility 400-2 is provided in another area, and there may be many more areas). The neighborhood facilities 400 are provided in locations different from the facility 200 that emits odorous gas and the deodorizing treatment device 100. The location of the neighborhood facilities 400 is not particularly limited, and it is preferable that they be provided comprehensively. The form of the neighborhood facilities 400 is not particularly limited. The neighborhood facilities 400 may be private houses or movable facilities. Sensors 402 provided outside the facility 400 (sensor 402-1 is provided at facility 400-1 in one area, and sensor 402-2 is provided at facility 400-2 in another area) measure, for example, one or more of the odor of the outside environment (not limited to ammonia), wind direction, atmospheric pressure, humidity, and temperature. It is preferable that the sensors 402 are provided in four different directions around the facility 400. The communication devices 401 installed in facility 400 (communication device 401-1 is installed in facility 400-1 in one region, and communication device 401-2 is installed in facility 400-2 in another region) communicate wirelessly with base stations 311 and 312, for example, using a 4G network or a 5G network.

[0091] Base stations 311 and 312 are connected to server 301 and user terminal 303 via the internet 302, and further to wireless user terminals 304 and 305 via another base station 313. User terminals 303 and wireless user terminals 304 and 305 may be located in a different location from the facility 200 that emits odorous gases, the deodorization treatment device 100, and facility 400, and may be located at a distance.

[0092] Server 301 receives measurement values ​​(data) transmitted from sensors 190-1 and 190-2 via communication devices 161-1 and 161-2 and stores them in its internal storage. Server 301 also receives measurement values ​​(data) transmitted from sensors 402-1 and 402-2 via communication devices 401-1 and 401-2 and stores them in its internal storage. The measurement values ​​(data) transmitted from multiple sensors 190-1, 190-2, 402-1, and 402-2 include ID information to distinguish the sensors and location information of the sensors. The frequency of acquiring measurement values ​​(data) into Server 301 may be, for example, once every 10 minutes, once every hour, once a day, once a week, or according to the instructions of user terminals 303 and 304. The acquired data may be from a single measurement or from multiple measurements (for example, 24 data points measured once every hour are transmitted once a day). By accumulating measurement values ​​(data) transmitted from multiple sensors 190-1, 190-2, 402-1, and 402-2, and analyzing their correlation over time using AI, it becomes possible to issue alerts for abnormal values ​​(described later), identify the source of odors, and make adjustments based on environmental factors.

[0093] A web server runs on server 301, and the measured values ​​acquired by this web server are displayed on the browser screens of user terminals 303, 304, and 305. It is desirable to display graphs so that the trends over time or on a daily basis can be understood. In addition, various measured values ​​for each region and each sensor may be displayed on a single web page, or various measured values ​​for multiple regions may be overlaid on a single graph. In this way, it becomes possible to centrally manage odors in deodorization treatment devices and neighboring facilities in multiple regions.

[0094] [Communication that does not go through a server] In the above example, the measured values ​​collected via server 301 were viewed on user terminals 303, 304, and 305. However, the software installed on user terminals 303, 304, and 305 (which is an applet (app) in the case of a smartphone) may directly receive the measured values ​​(data) from communication devices 161-1, 161-2, 401-1, and 401-2.

[0095] [Alerts due to abnormal values] If the odor measurement values ​​(data) transmitted from sensors 190-1, 190-2, 402-1, and 402-2 show abnormal values, or if an urgent response is required (alert), the control device 160 may be configured to push the data to the server 301 at its initiative. In this case, emergency information (alert information) may also be sent directly to user terminals 303, 304, and 305 using SMS or email protocols. The emergency information may include the sensor measurement values, ID information to distinguish the sensors, and location information of the sensors. The system administrator operating user terminals 303, 304, and 305 can take immediate action. For example, if sensor 190-1 detects an abnormal value exceeding a predetermined value, it is possible to adjust the operating status of the deodorizing treatment device 100-1, and if sensor 402-1 also detects an abnormal value, it is possible to apologize to facility 400-1. The adjustment of the operating status of the deodorizing treatment device 100-1 may be done by rushing to the site directly or by remote operation. Apologies to facility 400-1 can be made in person, or they can be compensated with pre-determined points or money.

[0096] [Identifying the source of the odor] Furthermore, the server 301 can identify the source of the odor from multiple deodorizing devices 100-1 and 100-2 by correlating the type, intensity, location, and direction of the odor transmitted from multiple sensors 190-1, 190-2, 402-1, and 402-2 with environmental factors such as wind direction, atmospheric pressure, humidity, and temperature. For example, even if sensors 190-1 and 190-2 do not detect an odor, if sensor 402-2 detects an odor after sensor 402-1, the server 301 can identify the source of the odor as the deodorizing device 100-1 by correlating the movement and delay time of the odor detection location with environmental factors such as wind direction, atmospheric pressure, humidity, and temperature before and after that time. In this case, the emergency information transmitted to user terminals 303, 304, and 305 may include information about the source of the odor.

[0097] [Adjustment based on environmental factors] Furthermore, the server 301 can adjust the operating conditions of the deodorizing treatment device 100 based on the type, intensity, location, and direction of odors transmitted from multiple sensors 190-1, 190-2, 402-1, and 402-2, as well as environmental factors such as wind direction, atmospheric pressure, humidity, and temperature. For example, since odors are more easily detected when the atmospheric pressure or humidity and temperature are high in a certain area, it is possible to adjust the operating conditions of the deodorizing treatment device 100 in that area.

[0098] [Control of deodorizing equipment from a remote location] By using the above system, the operating status of the deodorizing devices 100-1 and 100-2 can be managed on user terminals 303, 304, and 305. User terminals 303, 304, and 305 may be configured to send instructions to communication devices 161-1 and 161-2 via server 301 or directly, in response to user instructions, to control one or more of the following: the airflow rate of the first blower 152, the airflow rate of the second blower 182, the airflow rate of the third blower 186, the water spraying rate or water spraying frequency of the water spraying device 120, the amount of air bubbles generated in the liquid by the aeration device 142, the water supply and drainage to the water storage tank 140, and the temperature of the deodorizing tank 110.
