[0002] Deep underground spaces refer to confined spaces located 80 to 200 meters underground, relatively isolated from the outside world, with restricted access and poor natural ventilation. Common odors in deep underground spaces primarily originate from volatile organic compounds (VOCs) such as ammonia, hydrogen sulfide, methyl mercaptan, and methyl sulfide, as well as aldehydes and mold metabolites.

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0036] See also Figure 1 and Figure 2 , which shows an example of the deep space odor purification system provided by the present invention.

[0037] As can be seen from the figure, the deep space odor purification system of this example mainly includes a detection module 100, a removal module 200 and a control module 300.

[0038] The detection module 100 is distributed in the deep earth space 400 and is configured to sample the gas in the deep earth space 400 and detect the concentration of odor pollutants and environmental parameters in the deep earth space 400 in real time; the removal module 200 is distributed in the deep earth space 400, including an odor removal agent and an atomization device, the atomization device is configured to atomize the odor removal agent and spray it in the deep earth space 400, and can also adjust the droplet size of the odor removal agent according to the concentration of odor pollutants and environmental parameters. The odor removal agent is configured to actively target and capture odor and moldy components in the deep earth space 400; the management and control module 300 is configured to control the working states of the detection module 100 and the removal module 300, so as to accurately and efficiently purify the odor of the deep earth space 400, thereby improving the purification effect and reliability.

[0039] Among them, combined Figure 2 The detection modules 100 are distributed in different areas of the deep earth space 400. According to the size and shape of the deep earth space 400, multiple detection points are evenly distributed in the deep earth space 400, and a set of detection modules 100 is provided at each detection point to ensure that the detection modules 100 can cover the entire deep earth space 400 and detect the odor pollutant concentration and environmental parameters of each area in the deep earth space 400 in real time.

[0040] As an example, in a 1000m 3In the deep earth space 400, 5-8 detection modules 100 can be deployed and installed in the corners, center and areas with frequent human activities of the deep earth space 400 to ensure that the detection modules 100 can cover the deep earth space 400 and improve the reliability and accuracy of the detection results.

[0041] Further, combined with Figure 1 The detection module 100 includes a gas sampling unit 110, a multi-parameter sensor unit 120, a data acquisition and preprocessing unit 130 and a wireless communication unit 140, so that the gas sampling unit 110, the multi-parameter sensor unit 120, the data acquisition and preprocessing unit 130 and the wireless communication unit 140 cooperate with each other to realize real-time detection of odor and environment in the deep earth space 400.

[0042] Combine Figure 3 Specifically, the gas sampling unit 110 is composed of a micro air pump 111 and a sampling probe 112. The micro air pump 111 can provide suction for the sampling probe 112, so that the sampling probe 112 actively extracts gas samples from different areas of the deep space 400, ensuring the representativeness and accuracy of the gas samples.

[0043] Preferably, the sampling probe 112 is made of a corrosion-resistant and anti-interference probe, such as a perfluoroalkoxy resin probe or a ceramic probe, so that the sampling probe 112 can adapt to the harsh environmental conditions of high humidity and high dust in the deep earth space 400.

[0044] Here, the micro air pump 111 and the sampling probe 112 are conventional technical means in this field and are not described in detail here.

[0045] In coordination therewith, the multi-parameter sensor unit 120 is connected to the gas sampling unit 110 and is configured to detect the concentration of odor pollutants and environmental parameters in the gas samples collected by the gas sampling unit 110 in real time.

[0046] In order to improve the detection effect of the multi-parameter sensor unit 120, the multi-parameter sensor unit 120 includes an odor detection component 121 for detecting the concentration of odor pollutants in real time and an environment detection component 122 for detecting environmental parameters in real time.

[0047] Combine Figure 4 Furthermore, the multi-parameter sensor unit 120 is configured into a grid, and the odor detection component 121 and the environmental detection component 122 are arrayed on the grid and connected to the gas sampling unit 110 so that the gas sample collected by the gas sampling unit 110 can flow into the grid evenly, so that the odor detection component 121 and the environmental detection component 122 work simultaneously to detect the gas sample in real time.

[0048] Among them, the odor detection component 121 is composed of an array of electrochemical sensors, metal oxide semiconductor sensors and ion mobility spectrometry sensors. The electrochemical sensors specialize in specific toxic gases, such as CO, H2S, NO2, etc., and have high selectivity, while the metal oxide semiconductor sensors are sensitive to volatile organic compounds, methane, ethanol, etc. and have a wide coverage range. At the same time, the ion mobility spectrometry sensor is often used to detect complex mixtures and trace gases, with high sensitivity and fast response.

[0049] Therefore, the odor detection component 121 composed of an array of electrochemical sensors, metal oxide semiconductor sensors and ion mobility spectrometry sensors can simultaneously detect the gas concentrations of multiple gases, such as ammonia, hydrogen sulfide, methyl mercaptan, methyl sulfide, formaldehyde, and acetaldehyde, to obtain the concentration of odor pollutants in the deep earth space 400.

[0050] Furthermore, the environment detection component 122 is composed of a humidity sensor, a temperature sensor, and a wind speed sensor to detect humidity, temperature, and air velocity in real time to obtain environmental parameters in the bathymetric space 400 .

[0051] In this way, the multi-parameter sensor unit 120 can synchronously and real-timely detect the odor pollutant concentration and environmental parameters of the deep earth space 400 , provide working parameters for the cleaning module 200 , and ensure efficient purification of the deep earth space 400 .

[0052] Combine Figure 1 Furthermore, the multi-parameter sensor unit 120 transmits the odor pollutant concentration and environmental parameters to the data acquisition and preprocessing unit 130. The data acquisition and preprocessing unit 130 can collect and preprocess the odor pollutant concentration and environmental parameter signals output by the multi-parameter sensor unit 120 in real time to improve the accuracy of the odor pollutant concentration and environmental parameters.

[0053] Here, the data acquisition and preprocessing unit 130 is composed of a data acquisition chip and has built-in filtering, amplification, analog-to-digital conversion and other circuits, so that the data acquisition and preprocessing unit 130 can filter, amplify and analog-to-digital conversion the collected odor pollutant concentration and environmental parameter signals, improve the quality of the signal, and ensure the long-term stability and accuracy of the detection data of the multi-parameter sensor unit 120.

[0054] Here, the data acquisition and preprocessing unit 130 is a conventional technical means in this field and will not be described in detail here.

[0055] Combine Figure 1In coordination therewith, the wireless communication unit 140 is configured to transmit the processed odor pollutant concentration and environmental parameters to the control module 300, so that the control module 300 can control the working state of the removal module 200 according to the odor pollutant concentration and environmental parameters, ensuring that the removal module 200 can accurately and efficiently purify the deep earth space 400.

[0056] Here, the wireless communication unit 140 can be composed of a low-power wireless communication chip and support protocols such as ZigBee, LoRa, and NB-IoT, so that the wireless communication unit 140 can encrypt and transmit the concentration of odor pollutants and environmental parameters to ensure data security and reliability and realize real-time remote monitoring.

[0057] The detection module 100 thus constructed obtains the odor pollutant concentration and environmental parameters of the deep earth space 400 in real time through the cooperation of the gas sampling unit 110, the multi-parameter sensor unit 120, the data acquisition and preprocessing unit 130 and the wireless communication unit 140.

[0058] Combine Figure 2 In order to purify the odor of the deep space 400, the cleaning module 200 is distributed in the deep space 400. Preferably, the cleaning module 200 is distributed corresponding to the detection module 100, so that the cleaning module 200 can purify the odor of each area of the deep space 400 and improve the purification effect.

[0059] As an example, the removal module 200 can be set on the top and side walls of the deep underground space 400. At the same time, considering the ventilation conditions of the deep underground space 400, the removal module 200 can be installed in a position with relatively good air flow to enhance the diffusion effect of the odor removal agent.

[0060] Furthermore, the cleaning module 200 includes an odor removal agent 210 , which is configured to actively target and capture odor and moldy components in the deep space 200 , thereby accurately purifying and improving the odor purification effect and efficiency of the deep space 400 .

[0061] Combine Figure 1 Specifically, the odor removal agent 210 includes a composite active component 211, a nano-catalytic component 212 and a plant ester solvent base 213, so that the composite active component 211, the nano-catalytic component 212 and the plant ester solvent base 213 cooperate with each other to enhance the targeted capture efficiency and purification efficiency of the odor removal agent 210 for odors.

[0062] Among them, the composite active component 211 includes cationic active agents, plant extracts containing antioxidants and alkaloids, and fungicides, so that the cationic active agents, plant extracts containing antioxidants and alkaloids, and fungicides act synergistically to target and remove odor and musty components through chemical decomposition, oxidation-reduction, and adsorption.

[0063] As an example, cationic surfactants, such as quaternary ammonium salt surfactants, carry a positive charge and can undergo electrostatic adsorption with anions in odor molecules, such as hydrogen sulfide, sulfur-containing, nitrogen-containing and other anionic groups in ammonia, to form stable complexes to neutralize the odor. They can also wrap the odor molecules through intermolecular forces, reduce the volatility of the odor molecules, and prevent the spread of the odor.

[0064] Furthermore, plant extracts containing antioxidants and alkaloids, such as tea tree oil, citrus extract, pine needle extract, etc., convert odor molecules into odorless substances through redox reactions between antioxidants and alkaloids and odor molecules, for example, converting odor molecules such as thiols and amines into sulfate and nitrate odorless compounds, thereby blocking the generation of odor.

[0065] At the same time, fungicides, such as organosilicon quaternary ammonium salts and silver ion antibacterial agents, can destroy microbial cell membranes (such as benzalkonium chloride) or interfere with metabolic enzyme activity (such as isothiazolinone), inhibit the reproduction of mold and bacteria, and reduce metabolic odors (such as musty and corrupt odors), so as to block the process of microbial degradation of organic matter to produce odors such as hydrogen sulfide and indole, thereby effectively inhibiting the growth and reproduction of mold and reducing the generation of musty odors from the source.

[0066] In this way, the composite active component 211 targets and removes odor and moldy components through the cationic active agent, the plant extract containing antioxidants and alkaloids, and the fungicide, respectively, to improve the purification effect.

[0067] Correspondingly, the nano-catalytic component 212, such as nano-titanium dioxide and nano-zinc oxide, has a huge specific surface area and strong redox ability, can be evenly dispersed in the odor removal agent 210, fully contact with the odor molecules, and accelerate the decomposition reaction of the odor molecules. At the same time, under the irradiation of ultraviolet light or visible light, the nano-catalytic component 212 can also produce a photocatalytic effect, further enhancing the ability to degrade odor molecules.

[0068] Furthermore, the odor removing agent 210 includes a plant ester solvent base 213, and uses plant esters (such as coconut oil esters, olive oil esters, etc.) as the solvent base. Plant esters have good solubility and biodegradability, and can stably release the components of the odor removing agent 210 in a high humidity environment to avoid the influence of moisture on the effect of the agent. At the same time, plant esters also have certain antibacterial and antifungal properties, which can enhance the overall effect of the agent.

[0069] The odor removal agent 210 thus formed can achieve efficient odor removal, mold source inhibition and olfactory environment optimization, thereby efficiently and reliably purifying the odor of the deep underground space 400.

[0070] In order to evenly spray the odor removal agent 210 in the deep earth space 400 and improve the purification effect, the removal module 200 also includes an atomizing device 220. The atomizing device 220 is configured to atomize the odor removal agent 210 and spray it in various areas of the deep earth space 400. It can also adjust the droplet particle size of the odor removal agent 210 according to the odor pollutant concentration and environmental parameters detected by the detection module 100 to improve the purification efficiency of the deep earth space 400 and the utilization rate of the odor removal agent 210.

[0071] Combine Figure 5 Specifically, the atomizing device 220 includes an atomizing mechanism 221, a drug delivery mechanism 222 and a pneumatic delivery mechanism 223. The drug delivery mechanism 222 can accommodate the odor removal agent 210 and deliver the odor removal agent 210 to the atomizing mechanism 221. The pneumatic delivery mechanism 223 can provide a pressure gas source to the atomizing mechanism 221.

[0072] Furthermore, the first end of the atomizing mechanism 221 is provided with a high-frequency vibration plate 2211 for cooperating with the drug delivery mechanism 222, and the second end is cooperated with the pneumatic delivery mechanism 223, and an annular air outlet 2232 is provided at the end of the pneumatic delivery mechanism 223, so that the pneumatic delivery mechanism 223 delivers a pressure gas source, and the pressure gas source is ejected from the annular air outlet 2232, and moves along the outer wall of the annular air outlet 2232 under the action of pressure, thereby forming an annular air curtain 2212 at the second end of the atomizing mechanism 221. At the same time, a spiral guide groove 2213 is also provided on the middle inner wall of the atomizing mechanism 221.

[0073] In this way, the drug delivery mechanism 222 delivers the odor removal agent 210 to the first end of the atomization mechanism 221, and the vibration of the high-frequency vibration plate 2211 can break up the water molecules on the surface of the drug liquid, atomizing the odor removal agent 210 into droplets.

[0074] Here, the high-frequency vibration plate 211 is a conventional technical means in this field. As an example, the high-frequency vibration plate 211 can be composed of a piezoelectric ceramic ring and a metal diaphragm. When the control module 300 applies alternating current to the high-frequency vibration plate 211, the piezoelectric ceramic will produce a slight deformation, thereby driving the metal plate to vibrate. This vibration will cause the liquid water molecules on the surface of the odor removal agent 210 to be broken up, forming micron-sized droplet particles. Preferably, odor removal agent 210 droplets of 3-15μm are formed to ensure that the odor removal agent 210 is evenly sprayed and improve the purification effect.

[0075] At the same time, the control module 300 controls the vibration frequency of the high-frequency vibration plate 211 according to the environmental parameters, so as to adjust the droplet particle size. For example, if the humidity in the environmental parameters is greater than 90%, the control module 300 controls the vibration frequency of the high-frequency vibration plate 211 so that the high-frequency vibration plate 211 vibrates to break up the water molecules on the surface of the agent liquid, and atomizes the odor removal agent 210 to form ultrafine droplets, for example, droplets with a particle size of ≤5μm, so as to effectively avoid the condensation problem of droplets in a high humidity environment and ensure the uniform distribution of the agent in the deep earth space 400.

[0076] Furthermore, the droplets move along the spiral guide groove 2213 toward the annular air curtain 2212 , and the spiral guide groove 2213 can impart tangential velocity to the droplets, causing the droplets to form a primary vortex, gathering the droplet group toward the center, thereby reducing the loss caused by the droplets depositing on the inner wall of the atomization mechanism 221 .

[0077] At the same time, the annular air curtain 2212 formed by the pressure air source delivered by the pneumatic delivery mechanism 223 at the second end of the atomizing mechanism 221 will mix gas and liquid with the droplets, and perform secondary crushing of the droplets to form finer droplet particles. At the same time, the diffusion range of the droplets is restricted, ensuring that the droplets are concentratedly transported from the second end of the atomizing mechanism 221, preventing droplet loss and improving the utilization rate of the medicine.

[0078] Furthermore, a droplet outlet 2214 is formed at the second end of the atomizing mechanism 221 on the periphery of the annular air curtain 2212, and the droplet outlet 2214 extends obliquely toward the outside of the annular air curtain 2212 to form a droplet outlet 2214 with a gradually expanding caliber, so that the droplets of the odor removing agent 210 diffuse outward through the droplet outlet 2214, thereby improving the utilization rate of the agent and the spray coverage range of the droplets.

[0079] In conjunction with this, the atomizing device 220 also includes a rotating nozzle 224, which is arranged at the second end of the atomizing mechanism 221, and is hinged to the droplet outlet 2214, and a plurality of spraying ports 2241 are provided on the circumference and / or top surface of the rotating nozzle 224, so that the rotating nozzle 224 can rotate around the droplet outlet 2214, thereby adjusting the spraying direction of the droplets of the odor removal agent 210 to ensure precise purification.

[0080] Preferably, the rotating nozzle 224 can be hinged to the second end of the atomizing mechanism 221 through an existing slip ring, so that the rotating nozzle 224 can rotate, ensuring that the odor removal agent 210 droplets can be diffused in all directions to various areas of the deep space 400.

[0081] In order to improve the diffusion effect of the droplets, a drug flow regulating valve 2221 is provided in the drug delivery mechanism 222, and an air pressure regulating valve 2231 is provided in the air pressure delivery mechanism 223. The drug flow regulating valve 2221 and the air pressure regulating valve 2231 are respectively connected to the control module 300, so that the control module 300 can adjust the drug flow and air pressure according to the concentration of odor pollutants to adjust the gas-liquid mixing ratio, control the particle size and density of the droplets, and make the droplets accurately sprayed in the deep space 400 for odor purification.

[0082] As an example, if the concentration of odor pollutants is high, the control module 300 increases the opening of the agent flow regulating valve 2221 and the air pressure regulating valve 2231 to increase the agent flow and air pressure, thereby increasing the gas-liquid mixing and increasing the density of the droplets. Correspondingly, if the humidity is low, the control module 300 reduces the opening of the air pressure regulating valve 2231 to generate droplets with larger particle sizes, prolong the residence time of the agent in the air, and enhance the purification effect.

[0083] The atomizing device 220 thus constructed cooperates with the atomizing mechanism 221, the agent delivery mechanism 222 and the air pressure delivery mechanism 223 to spray droplets of odor removing agent 210 to various areas of the deep earth space 400, and adjusts the vibration frequency of the high-frequency vibration plate 211 and the opening of the agent flow regulating valve 2221 and the air pressure regulating valve 2231 according to the concentration of odor pollutants and environmental parameters, and adjusts the droplet particle size for the second time to achieve on-demand matching of droplets, which can solve the problem of high-humidity condensation of droplets, and achieve precise purification to improve the purification effect.

[0084] Combine Figure 1 In order to ensure the reliability of the purification system, the purification system also includes a control module 300. The control module 300 is configured to distribute and control the working states of the detection module 100 and the removal module 200 to ensure the high efficiency and effectiveness of the odor purification of the deep space 400.

[0085] Specifically, the management and control module 300 is connected to the gas sampling unit 110 of the detection module 100 to control the open state of the gas sampling unit 110, so that the gas sampling unit 110 continuously samples the gas in the deep earth space 400, thereby enabling the multi-parameter sensor unit 120 and the data acquisition and preprocessing unit 130 to cooperate with each other to detect and process the odor pollutant concentration and environmental parameters in the deep earth space 400 in real time.

[0086] At the same time, the control module 300 is connected to the wireless communication unit 140 of the detection module 100 to receive the odor pollutant concentration and environmental parameters transmitted by the wireless communication unit 140 in real time, and controls the working status of the removal module 200 accordingly.

[0087] Furthermore, the control module 300 is also connected to the high-frequency vibration plate 211 of the removal module 200, providing alternating current to the high-frequency vibration plate 211, so that the high-frequency vibration plate 211 atomizes the odor removal agent 210 to form droplets, and controls the vibration frequency of the high-frequency vibration plate 211 according to environmental parameters, and adjusts it to the droplet particle size to avoid condensation problems of droplets in high humidity environments, thereby ensuring uniform distribution of the agent in the deep earth space 400.

[0088] Correspondingly, the control module 300 is connected to the agent flow regulating valve 2221 and the air pressure regulating valve 2231 of the cleaning module 200, and adjusts the opening of the agent flow regulating valve 2221 and the air pressure regulating valve 2231 respectively to control the agent flow and air pressure, adjust the gas-liquid mixing ratio, and control the particle size and density of the droplets, so that the droplets are accurately sprayed in the deep space 400 for odor purification.

[0089] Here, the management and control module 300 can be composed of an existing control cabinet or a remote controller to ensure effective control of the detection module 100 and the removal module 200.

[0090] This constitutes the deep-earth space odor purification system provided by the present invention.

[0091] The present invention also provides a method for purifying deep-earth odors. Based on the deep-earth odor purification system constructed by the above-mentioned scheme, the purification method includes:

[0092] First, the gas in the deep earth space 400 is sampled through the detection module 100, and the odor pollutant concentration and environmental parameters in the deep earth space 400 are detected in real time, and the odor pollutant concentration and environmental parameters are transmitted to the management and control module 300.

[0093] Combine Figure 1 and Figure 2 The detection modules 100 are distributed in different areas of the deep earth space 400. The micro air pump 111 in the gas sampling unit 110 provides suction to the sampling probe 112, so that the sampling probe 112 actively extracts gas samples from different areas of the deep earth space 400, ensuring the representativeness and accuracy of the gas samples.

[0094] The gas samples collected by the gas sampling unit 110 flow evenly into the multi-parameter sensor unit 120 with a grid structure, so that the odor detection component 121 and the environmental detection component 122 work simultaneously, and detect the gas samples in real time to obtain the odor pollutant concentration (such as the gas concentration of ammonia, hydrogen sulfide, methyl mercaptan, methyl sulfide, formaldehyde, and acetaldehyde) and environmental parameters (humidity, temperature, and airflow velocity) in the deep earth space 400.

[0095] Furthermore, the data acquisition and preprocessing unit 130 can filter, amplify and perform analog-to-digital conversion on the odor pollutant concentration and environmental parameter signals to improve the accuracy of the odor pollutant concentration and environmental parameters, and transmit them to the management and control module 300 through the wireless communication unit 140.

[0096] At that time, the management and control module 300 controls the working state of the atomization device 220 in the removal module 200 according to the concentration of odor pollutants and environmental parameters, atomizes the odor removal agent 210, and adjusts the droplet particle size of the odor removal agent 210, and sprays the droplets in the deep space, so that the droplets of the odor removal agent 210 actively target and capture the odor and musty components in the deep space 400.

[0097] Specifically, the drug delivery mechanism 222 delivers the odor removal agent 210 to the first end of the atomization mechanism 221, and the management and control module 300 controls the high-frequency vibration plate 2211 to vibrate and break up the water molecules on the surface of the drug liquid, atomizing the odor removal agent 210 to form droplets, and controls the vibration frequency of the high-frequency vibration plate 211 according to environmental parameters, adjusts the droplet particle size, and prevents the droplets from condensing in a high-humidity environment.

[0098] At the same time, the air pressure delivery mechanism 223 delivers pressure air source to the second end of the atomizing mechanism 221 to form an annular air curtain 2212, so that the mist droplets move along the spiral guide groove 2213 toward the annular air curtain 2212, and mix gas and liquid with the annular air curtain 2212 at the second end of the atomizing mechanism 221.

[0099] The control module 300 adjusts the opening of the agent flow control valve 2221 and the air pressure control valve 2231 according to the concentration of odor pollutants, adjusts the agent flow and air pressure to adjust the gas-liquid mixing ratio, control the particle size and density of the droplets, and improve the diffusion effect of the droplets.

[0100] Furthermore, the angle of the rotating nozzle 224 is adjusted so that the mist droplets are precisely sprayed into the deep space 400 through the rotating nozzle 224 to purify the odor.

[0101] The following examples illustrate the working process of the present invention in a specific application. It should be noted that the content described here is only a specific application example of this solution and does not constitute a limitation to this solution.

[0102] Combine Figure 6 , taking the deep underground laboratory and the storage space of the deep underground laboratory as the deep underground space 400 as examples, the specific application of this purification system is explained.

[0103] Example 1

[0104] Deep Space 400 is a deep underground laboratory. There is a distinct smell of ammonia and hydrogen sulfide in the deep underground laboratory, and the humidity in the space is maintained at around 90% all year round.

[0105] The purification system is used for treatment. First, the detection ring module 100 detects that the ammonia concentration is 1.5 mg / m 3 , hydrogen sulfide concentration is 0.05mg / m 3 , humidity is 90% RH, and temperature is 26℃.

[0106] Based on the detection data, the control module 300 starts the atomization device 220 in the removal module 200, and controls the opening of the agent flow control valve 2221 and the air pressure control valve 2231, adjusting the air pressure to 0.5MPa and the agent flow to 1L / min to generate droplets with a particle size of about 8μm. (Because the humidity is greater than 90%, the vibration frequency of the high-frequency vibration plate is adjusted, and some agents generate ultrafine droplets of ≤5μm). The rotating nozzle 224 evenly sprays the droplets of the odor removal agent 210 in the deep laboratory space.

[0107] The copper ion modified covalent organic framework (COF-Cu) in the odor removal agent 210 reacts rapidly with hydrogen sulfide, selectively adsorbs mercaptans through the Cu-S bond, and catalytically decomposes them into odorless dimethyl disulfide (CH3SSCH3), reducing the hydrogen sulfide concentration to 0.005 mg / m 3 , lower than the first level standard of GB 14554-93 (≤0.03mg / m 3 ); At the same time, citric acid modified mesoporous silica (MSN-CA) reacts with ammonia to produce stable ammonium salt crystals, reducing the ammonia concentration to 0.6 mg / m 3 , better than the first level standard of GB 14554-93 (≤1.0mg / m 3 ).

[0108] At the same time, the utilization rate of the reagents reached about 85%, effectively solving the odor problem of the deep underground laboratory and ensuring the stable operation of the system.

[0109] Example 2

[0110] Deep Space 400 is the storage space of the Deep Laboratory, which has a serious musty odor problem, mainly caused by mold spores and aldehydes.

[0111] First, the detection ring module 100 detects that the mold spore concentration is 0.5 mg / m 3 , formaldehyde concentration is 0.6mg / m 3 , acetaldehyde concentration is 30mg / m 3 , humidity is 85% RH, and temperature is 24℃.

[0112] Based on the detection data, the control module 300 starts the atomization device 220 in the removal module 200, and controls the opening of the agent flow regulating valve 2221 and the air pressure regulating valve 2231, adjusting the air pressure to 0.3 MPa and the agent flow to 0.5 L / min to generate droplets with a particle size of 10 μm. The rotating nozzle 224 evenly sprays the droplets of the odor removal agent 210 in the deep laboratory space.

[0113] The benzalkonium chloride-chitosan composite slow-release particles in the odor removal agent 21 use quaternary ammonium salts to destroy the mold cell wall, and on the other hand, they inhibit the spread of spores through chitosan film formation, reducing the mold spore concentration to 0.15 mg / m 3 , in line with GBZ 2.1-2019 PC-TWA (0.3-1.0mg / m 3 ) standard; soybean ethyl sulfate morpholine catalyzes the oxidation of aldehydes to CO2 and H2O, reducing the formaldehyde concentration to 0.2 mg / m 3 , acetaldehyde concentration dropped to 18mg / m 3 , all meet the corresponding national standards, with a drug utilization rate of 88%, which is significantly better than traditional atomization equipment and effectively improves the olfactory environment of the deep underground storage space.

[0114] It can be seen that this purification system can effectively improve the purification effect and reliability.

[0115] Combine Figure 7 Furthermore, compared with traditional purification systems, the removal module 200 of the purification system of the present invention can adjust the droplet particle size to ensure that the droplets are not condensed at a humidity of 90%. At the same time, the agent utilization rate of the traditional purification system is 35%, while the agent utilization rate of the purification system is 88%, which is more than twice that of the traditional purification system, and can efficiently and reliably purify odors in deep underground spaces.
