Description

Technical Field

[0001] This utility model relates to the technical field of deodorization devices, and more specifically, to an improved biochemical tank deodorization linkage control system. Background Technology

[0002] A biological treatment tank is a type of wastewater treatment equipment primarily used to remove suspended organic matter from domestic sewage. It utilizes sedimentation and anaerobic fermentation principles for primary, transitional wastewater treatment. A biological treatment tank comprises multiple chambers, such as anaerobic, aerobic, and anoxic chambers, which work together to achieve efficient wastewater treatment. Furthermore, a biological treatment tank can also be viewed as a type of stationary biological oxidation method, where packing material is placed in an aeration tank, utilizing a biofilm to adsorb and degrade organic matter in the wastewater.

[0003] During the wastewater treatment process in biological treatment ponds, a large amount of foul odor is generated. Long-term inhalation of this odor can negatively impact human health, so deodorization devices are typically used to treat it. If the blower is operating at a high degree of openness, normal ambient air will be drawn into the deodorization system, increasing energy consumption and reducing deodorization efficiency. Furthermore, prolonged high-load operation increases blower wear and tear. Conversely, if the blower is operating at a low degree of openness, deodorization efficiency will also decrease, and there is a risk of odor overflow. Currently, adjustments can only be made manually based on air quality sensors and gas detectors, which is time-consuming, labor-intensive, and difficult to precisely control. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies in that it is difficult to accurately adjust the air volume of deodorizing fans, and to provide an improved biochemical tank deodorization linkage control system that can reasonably adjust the air volume of the fans.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An improved biochemical tank deodorization linkage control system is provided, including a biochemical tank, a deodorization system, and a deodorization fan, wherein the biochemical tank, the deodorization system, and the deodorization fan are connected in sequence; it also includes a negative pressure gauge and a control module, wherein the negative pressure gauge is installed in the biochemical tank, and both the deodorization fan and the negative pressure gauge are communicatively connected to the control module.

[0007] This invention relates to an improved biochemical tank deodorization linkage control system. After the biochemical tank reacts with wastewater, the resulting odorous gas is drawn into the deodorization system by a deodorizing fan for deodorization, and then discharged by the same fan. During the deodorization process, a negative pressure gauge located inside the biochemical tank monitors the pressure. When the gauge detects that the pressure inside the tank may exceed atmospheric pressure, indicating a risk of odor overflow, the control module increases the opening of the deodorizing fan, increasing its airflow. Conversely, when the gauge detects that the pressure is too low, allowing ambient air to be drawn into the system, the control module reduces the fan's opening, decreasing its airflow. By using a negative pressure gauge to monitor the negative pressure inside the biochemical tank in real time, and communicating with both the gauge and the deodorizing fan via a control module, the control module can adjust the fan's opening based on the negative pressure readings, thus enabling reasonable adjustment of the fan's airflow.

[0008] Furthermore, it also includes a biological treatment tank blower, which is connected to the biological treatment tank and blows air towards the tank. By installing the blower, air can be blown into the biological treatment tank, achieving active air circulation and improving the efficiency of treating odors generated in the tank.

[0009] Furthermore, the biological treatment tank has an air inlet and an air outlet. The air inlet is located at the bottom of the biological treatment tank, and the biological treatment tank blower is connected to the biological treatment tank through the air inlet. The air outlet is located at the top of the biological treatment tank, and the deodorizing blower is connected to the biological treatment tank through the air outlet. By placing the air inlet at the bottom of the biological treatment tank, direct ventilation can be provided, which can disturb the biological treatment tank and accelerate the discharge of odors, thereby improving the efficiency of odor treatment. At the same time, the odors are drawn out from the top, which can prevent the sewage in the biological treatment tank from being drawn out during exhaust.

[0010] Furthermore, the negative pressure gauge is located in the middle of the biochemical tank. By placing the negative pressure gauge in the middle of the biochemical tank, interference from the biochemical tank fan and deodorizing fan can be avoided, allowing the negative pressure gauge to more accurately detect the negative pressure inside the biochemical tank, thereby enabling better control of the fan airflow.

[0011] Furthermore, a biochemical tank airflow meter is installed between the biochemical tank fan and the biochemical tank, and a deodorizing airflow meter is installed between the deodorizing fan and the biochemical tank. Both the biochemical tank airflow meter and the deodorizing airflow meter are communicatively connected to the control module. The airflow of the biochemical tank fan and the deodorizing fan is detected by the biochemical tank airflow meter and the deodorizing airflow meter. After detecting the airflow, the detection is fed back to the control module, which then adjusts the biochemical tank fan and the deodorizing fan according to the feedback value, allowing the control module to more accurately control the biochemical tank fan and the deodorizing fan.

[0012] Furthermore, the biological treatment tank blower includes a biological treatment tank blower and an inlet air volume regulating valve, the inlet air volume regulating valve being connected between the biological treatment tank blower and the biological treatment tank. The deodorizing blower includes a deodorizing blower and an outlet air volume regulating valve, the outlet air volume regulating valve being connected between the deodorizing blower and the biological treatment tank. Both the inlet air volume regulating valve and the outlet air volume regulating valve are communicatively connected to the control module. The control module adjusts the opening degree of the biological treatment tank blower and the deodorizing blower by regulating the inlet air volume regulating valve and the outlet air volume regulating valve, thereby regulating the air volume of the biological treatment tank blower and the deodorizing blower.

[0013] Furthermore, the system also includes instruments for the biological treatment tank, which are installed inside the biological treatment tank and are communicatively connected to the control module. The instruments monitor the data of the biological treatment tank in real time and feed the values ​​back to the control module. The control module adjusts the airflow of the deodorizing blower based on the feedback values, enabling reasonable adjustment of the blower's airflow.

[0014] Furthermore, the biological treatment tank instruments include a sludge concentration meter and a dissolved oxygen meter, both of which are located within the biological treatment tank and are communicatively connected to the control module. By detecting the sludge concentration and dissolved oxygen content in the biological treatment tank using the sludge concentration meter and dissolved oxygen meter, the airflow of the blower can be adjusted appropriately.

[0015] Furthermore, it also includes a water inlet pipe. The biochemical tank has a water inlet, and the water inlet pipe is located at the water inlet. A water inlet instrument is installed on the water inlet pipe, and the water inlet instrument is communicatively connected to the control module. The water inlet instrument detects the incoming water, and the airflow of the deodorizing blower is adjusted according to the incoming water, allowing for reasonable adjustment of the blower's airflow.

[0016] Furthermore, it also includes an alarm, which is communicatively connected to the control module. By setting the alarm, an alert can be triggered when the values ​​are abnormal, thus promptly notifying the operators of any discrepancies.

[0019] 2. The present invention provides an improved biochemical tank deodorization linkage control system, which detects the air volume of the biochemical tank fan and the deodorization fan through a biochemical tank air volume meter and a deodorization air volume meter. After detecting the air volume, the system feeds it back to the control module, which then adjusts the biochemical tank fan and the deodorization fan according to the feedback value, so that the control module can more accurately control the biochemical tank fan and the deodorization fan.

[0027] Example 1

[0028] This embodiment is the first embodiment of an improved biological tank deodorization linkage control system, such as... Figure 1 As shown, the system includes a biological treatment tank 100, a deodorization system 200, and a deodorization fan 300, which are connected in sequence. It also includes a negative pressure gauge 400 and a control module 500. The negative pressure gauge 400 is located inside the biological treatment tank 100. Figure 3 As shown, both the deodorizing fan 300 and the negative pressure gauge 400 are communicatively connected to the control module 500.

[0029] It also includes a biological treatment tank blower 600, which is connected to the biological treatment tank 100, with the blower 600 directing airflow towards the tank. By installing the blower 600, the biological treatment tank 100 can be aerated, achieving active air circulation and improving the efficiency of odor treatment. The biological treatment tank 100 includes an anaerobic section, an anoxic section, and an oxygen-consuming section. The blower 600 is installed in the oxygen-consuming section, which also produces the most odor.

[0030] A biochemical tank airflow meter 610 is installed between the biochemical tank fan 600 and the biochemical tank 100, and a deodorizing airflow meter 310 is installed between the deodorizing fan 300 and the biochemical tank 100. Both the biochemical tank airflow meter 610 and the deodorizing airflow meter 310 are communicatively connected to the control module 500. The airflow of the biochemical tank fan 600 and the deodorizing fan 300 is detected by the biochemical tank airflow meter 610 and the deodorizing fan 300, and the detected airflow is fed back to the control module 500. The control module 500 then adjusts the biochemical tank fan 600 and the deodorizing fan 300 according to the feedback value, so that the control module 500 can more accurately control the biochemical tank fan 600 and the deodorizing fan 300.

[0031] The biological treatment tank blower 600 includes a biological treatment tank blower 620 and an inlet air volume regulating valve 630, which connects the biological treatment tank blower 620 and the biological treatment tank 100. The deodorizing blower 300 includes a deodorizing blower 320 and an outlet air volume regulating valve 330, which connects the deodorizing blower 320 and the biological treatment tank 100. Both the inlet air volume regulating valve 630 and the outlet air volume regulating valve 330 are communicatively connected to the control module 500. The control module 500 adjusts the opening degree of the biological treatment tank blower 620 and the deodorizing blower 320 by regulating the inlet air volume regulating valve 630 and the outlet air volume regulating valve 330, thereby regulating the air volume of the biological treatment tank blower 600 and the deodorizing blower 320. In this embodiment, the biochemical tank blower 600 and the deodorization blower 300 are Howton centrifugal blowers, model SG30A-CVC. The opening degree of the blowers can be directly adjusted through the control module 500.

[0032] It also includes an alarm 900, which is communicatively connected to the control module 500. By configuring the alarm 900, it can trigger an alarm when values ​​are abnormal, promptly alerting operators to these anomalies. The alarm 900 is preferably an audible and visual alarm, alerting operators with flashing lights and sound when an alarm is triggered.

[0033] The working principle of the improved biological tank deodorization linkage control system in this embodiment is as follows:

[0034] After the wastewater reacts in the biological treatment tank 100, the resulting odorous gas is drawn into the deodorization system 200 by the deodorization fan 300 for deodorization, and then discharged by the deodorization fan 300. During the deodorization process, a negative pressure gauge 400 is located inside the biological treatment tank 100 to monitor the pressure inside the biological treatment tank 100. A limit is set for the negative pressure gauge 400. When the negative pressure gauge 400 detects that the air pressure inside the biological tank 100 has risen to a level that may be greater than atmospheric pressure, there is a risk of odor overflow. The control module 500 increases the opening degree of the deodorizing fan 300 and / or decreases the opening degree of the biological tank fan 600, increasing the suction volume of the deodorizing fan 300 and / or decreasing the blowing volume of the biological tank fan 600 until the biological tank 100 re-establishes negative pressure. When the negative pressure gauge 400 detects that the air pressure inside the biological tank 100 is too low, normal air in the environment is also drawn into the deodorizing system 200. The control module 500 decreases the opening degree of the deodorizing fan 300 and / or increases the opening degree of the biological tank fan 600, decreasing the suction volume of the deodorizing fan 300 and / or increasing the blowing volume of the biological tank fan 600. By setting up a negative pressure gauge 400 to detect the negative pressure in the biochemical tank 100 in real time, and using a control module 500 to communicate with both the negative pressure gauge 400 and the deodorizing fan 300, the control module 500 controls the opening of the deodorizing fan 300 in real time according to the negative pressure of the negative pressure gauge 400. Under the premise of ensuring that the ambient air quality meets the standards and personnel safety, the air volume of the fan is reasonably adjusted, the energy consumption of the deodorizing fan is reduced, and the safety and system intelligence are improved.

[0035] Example 2

[0036] This embodiment is the second embodiment of the improved biological tank deodorization linkage control system. This embodiment is similar to the first embodiment, except that, as Figure 2 As shown, the biological treatment tank 100 has an air inlet 110 and an air outlet 120. The air inlet 110 is located at the bottom of the biological treatment tank 100, and the biological treatment tank blower 600 is connected to the biological treatment tank 100 through the air inlet 110. The air outlet 120 is located at the top of the biological treatment tank 100, and the deodorizing blower 300 is connected to the biological treatment tank 100 through the air outlet 120. By placing the air inlet 110 at the bottom of the biological treatment tank 100, the biological treatment tank 100 is directly ventilated, which can disturb the biological treatment tank 100, accelerate the discharge of odors, and thus improve the odor treatment efficiency. At the same time, the odors are sucked out from the top, which can prevent the sewage in the biological treatment tank 100 from being sucked out during exhaust.

[0037] The negative pressure gauge 400 is located in the middle of the biological treatment tank 100. By placing the negative pressure gauge 400 in the middle of the biological treatment tank 100, interference from the biological treatment tank fan 600 and the deodorizing fan 300 on the detection of the negative pressure gauge 400 can be avoided, allowing the negative pressure gauge 400 to more accurately detect the negative pressure inside the biological treatment tank 100, thereby enabling better control of the fan airflow.

[0038] Example 3

[0039] This embodiment is the third embodiment of the improved biological tank deodorization linkage control system. This embodiment is similar to Embodiment 1, except that, as... Figure 1 As shown, it also includes a biological treatment tank instrument 700, which is installed inside the biological treatment tank 100 and is communicatively connected to the control module 500. The biological treatment tank instrument 700 monitors the data of the biological treatment tank 100 in real time and feeds back the values ​​to the control module 500. The control module 500 adjusts the airflow of the deodorizing blower 320 according to the feedback values, thus enabling reasonable adjustment of the blower's airflow.

[0040] like Figure 3 As shown, the biological treatment tank instrument 700 includes a sludge concentration meter 710 and a dissolved oxygen meter 720, both of which are located within the biological treatment tank 100 and are communicatively connected to the control module 500. By detecting the sludge concentration and dissolved oxygen content in the biological treatment tank using the sludge concentration meter 710 and dissolved oxygen meter 720, the airflow of the blower can be adjusted accordingly. When the sludge concentration is high, the opening of the deodorization blower 300 and the biological treatment tank blower 600 needs to be increased. When the dissolved oxygen is low, the opening of the biological treatment tank blower 600 needs to be increased.

[0041] like Figure 2 and Figure 3 As shown, it also includes an inlet pipe 800. The biological treatment tank 100 has an inlet 130, and the inlet pipe 800 is located at the inlet 130. An inlet instrument 810 is installed on the inlet pipe 800, and the inlet instrument 810 is communicatively connected to the control module 500. The inlet instrument 810 detects the incoming water and adjusts the airflow of the deodorizing blower 320 according to the incoming water, thus reasonably adjusting the blower's airflow. The inlet instrument 810 mainly detects the incoming water quality and quantity. When the incoming water quality is poor or the incoming water quantity is large, the opening of the biological treatment tank blower 600 and the deodorizing blower 300 needs to be increased accordingly.
