Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and particularly relates to a multi-stage waste gas treatment biological deodorization pool. Background Technique

[0002] In chemical production, such as organic synthesis and the synthesis of active pharmaceutical ingredients in pharmaceutical production, a large amount of organic substances are used. The process emits unpleasant odors, and the generated wastewater also emits unpleasant odors, causing environmental odor pollution in sewage treatment plants and other places. At present, people often use biological deodorization pools to treat waste gas, which can achieve the purpose of purifying waste gas.

[0003] Biological deodorization mainly uses microorganisms to deodorize. Through the physiological metabolism of microorganisms, odoriferous substances are transformed, and target pollutants are effectively decomposed and removed to achieve the purpose of treating malodor. However, most of the existing biological deodorization filters have a simple structure, cannot achieve multi-stage treatment, the treatment effect is still not ideal, and it is difficult to ensure the activity of microorganisms during use, resulting in poor purification effect, so that the discharged waste gas still has a large impact on the environment and brings unnecessary trouble to users.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a multi-stage waste gas treatment biological deodorization pool.

[0005] The information disclosed in this background technical section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art.

[0008] An exhaust gas input pipe is fixedly connected to the deodorization pool main body, and an activated carbon adsorption plate is installed on the deodorization pool main body;

[0009] The biological deodorization mechanism is installed in the deodorization pool main body.

[0010] The spray purification mechanism is installed below one of the support inclined plates. The spray purification mechanism includes a support block, in which a spray chamber and a sprinkling chamber are drilled. A plurality of sprinkler heads and spray nozzles are installed on the support block, and a plurality of the spray nozzles are arranged on one side close to the bottom of the support block.

[0011] In one or more embodiments of the present invention, a fixed frame is fixed in the deodorization tank body.

[0012] In one or more embodiments of the present invention, one-way valves are installed at one ends of the plurality of discharge pipes far away from the branch thin pipes, so that the clear water liquid is not prone to backflow, and thus the discharge of the waste gas is not easily affected.

[0016] A plurality of uniformly distributed rotating push blocks are installed on the transmission support shaft for pushing the sliding liquid guide plate to move, so that one surface of the sliding liquid guide plate can be flush with the liquid guide rod, so that the liquefied water droplets can slide down along, and are not likely to directly drip onto the nutrients, and thus are not likely to increase the humidity of the nutrients, ensuring the activity of the microorganisms.

[0017] In one or more embodiments of the present utility model, a plurality of shrinkage grooves are formed in the heat-conducting support plate.

[0018] A fixing spring is fixedly connected between the limiting plate and the heat-conducting support plate to push the limiting plate, so that the limiting plate pulls the limiting strip rod and the sliding liquid guide plate, and thus one surface of the sliding liquid guide plate is no longer flush with the liquid guide rod. At this time, the liquefied water droplets will gather at the end of the liquid guide rod away from the heat-conducting support plate and finally drip downward into the nutrient substance to increase the humidity in the nutrient substance.

[0019] In one or more embodiments of the present utility model, a drainage plate is arranged on one side of the heat-conducting support plate to guide and discharge the liquefied and gathered water droplets, so that the water droplets are not easily directly dripped into the nutrient substance and the humidity of the nutrient substance is not easily increased.

Detailed implementation manners

[0034] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0035] As Figures 1-7 shown, a multi-stage waste gas treatment biological deodorization pool in an embodiment of the present utility model includes: a deodorization pool main body 1, a biological deodorization mechanism 2, and a spray purification mechanism 3.

[0036] As Figures 1-4 shown, an exhaust gas input pipe 101 is fixedly connected to the deodorization pool main body 1 for introducing exhaust gas into the deodorization pool main body 1. An activated carbon adsorption plate 102 is installed on the deodorization pool main body 1 for performing the last-stage purification treatment on the exhaust gas, so as to improve the purification effect on the exhaust gas and achieve multi-stage exhaust gas treatment.

[0037] As Figures 1-6 shown, a fixed frame 103 is fixed inside the deodorization pool main body 1. The fixed frame 103 is communicated with the exhaust gas input pipe 101, which is convenient for introducing the exhaust gas into a plurality of branch thin pipes 104, and then enabling the exhaust gas to diffuse separately, thereby improving the purification effect of the exhaust gas. A plurality of branch thin pipes 104 are installed on the fixed frame 103 for transporting the exhaust gas. A plurality of uniformly distributed discharge pipes 105 are fixedly connected to the branch thin pipes 104 for introducing the exhaust gas into the clear water liquid.

[0038] Specifically, a one-way valve 106 is installed at one end of the plurality of discharge pipes 105 away from the branch thin pipes 104, so that the clear water liquid is not prone to backflow, and thus the discharge of the exhaust gas is not easily affected. A drain pipe 107 is also installed at the bottom of the deodorization pool main body 1 for discharging the liquid inside the deodorization pool main body 1. A plug is provided at the other end of the drain pipe 107.

[0039] As Figures 1-3As shown in the figure, the biological deodorization mechanism 2 is installed inside the deodorization tank main body 1. The biological deodorization mechanism 2 includes a plurality of support inclined plates 201 for supporting the nutrient substance 202 to prevent the nutrient substance 202 from falling off easily. The nutrient substance 202 is fixedly arranged on each of the plurality of support inclined plates 201. The nutrient substance 202 is composed of a carbon source, a nitrogen source, a phosphorus source, and trace elements such as iron, zinc, and manganese, and is used for the growth of microorganisms. Below the plurality of support inclined plates 201, there is a heat-conducting support plate 203 for supporting the liquid guide rod 205 and a plurality of sliding liquid guide plates 204, and it has the function of heat conduction. Preferably, a humidity sensor is arranged inside the nutrient substance 202 to control the start and stop of the driving motor 209, and thus facilitate the control of the humidity inside the nutrient substance 202.

[0040] Specifically, a plurality of sliding liquid guide plates 204 are slidably arranged on the heat-conducting support plate 203. A liquid guide rod 205 is fixed to one side of the sliding liquid guide plate 204. When the plurality of sliding liquid guide plates 204 are flush with the liquid guide rod 205, the liquefied water droplets will flow downward along the flush plane of the sliding liquid guide plate 204 and the liquid guide rod 205, and thus are not likely to directly drip into the nutrient substance 202, and are not likely to increase the humidity inside the nutrient substance 202. When the plurality of sliding liquid guide plates 204 are no longer flush with the liquid guide rod 205, the liquefied water droplets will gather at the lower end of the liquid guide rod 205 and then drip into the nutrient substance 202, thereby increasing the humidity of the nutrient substance 202 and maintaining the activity of microorganisms.

[0041] As Figures 1-7 shown in the figure, one end of the plurality of heat-conducting support plates 203 is fixedly connected with a heat exchange plate 206 for accelerating the heat dissipation of the heat-conducting support plate 203 to make the temperature of the heat-conducting support plate 203 lower. The heat exchange plate 206 is fixed on the deodorization tank main body 1. A plurality of evenly distributed heat dissipation fins 207 are installed on the heat exchange plate 206 to improve the heat dissipation effect and enhance the heat dissipation effect of the heat exchange plate 206 and the heat-conducting support plate 203.

[0042] As Figures 1-3 shown in the figure, a driving motor 209 is installed inside the heat-conducting support plate 203 for driving the transmission support shaft 208 to rotate, so that the transmission support shaft 208 can drive a plurality of rotating push blocks 210 to rotate, and thus provide power for pushing the sliding of the sliding liquid guide plate 204. The driving motor 209 is fixedly connected with the transmission support shaft 208 for supporting a plurality of rotating push blocks 210 and driving a plurality of rotating push blocks 210 to rotate. A plurality of evenly distributed rotating push blocks 210 are installed on the transmission support shaft 208 for pushing the sliding liquid guide plate 204 to move, so that one side of the sliding liquid guide plate 204 can be flush with the liquid guide rod 205, so that the liquefied water droplets can slide downward along it and are not likely to directly drip onto the nutrient substance 202, and thus are not likely to increase the humidity of the nutrient substance 202 and ensure the activity of microorganisms.

[0043] Among them, a plurality of shrinkage grooves are bored in the heat-conducting support plate 203, and a limiting plate 212 is arranged in the shrinkage groove to limit the limiting bar 211, so that the sliding liquid guide plate 204 is not easy to fall off directly. The limiting bar 211 is fixedly connected between the limiting plate 212 and the sliding liquid guide plate 204, which is used to support the sliding liquid guide plate 204 so that the sliding liquid guide plate 204 can slide, thereby facilitating the adjustment of the position of the sliding liquid guide plate 204.

[0044] In addition, a fixed spring 213 is fixedly connected between the limit plate 212 and the heat-conducting support plate 203, which is used to push the limit plate 212, so that the limit plate 212 pulls the limit bar 211 and the sliding liquid guiding plate 204, and then one side of the sliding liquid guiding plate 204 is no longer flush with the liquid guiding rod 205. At this time, the liquefied water droplets will gather at the end of the liquid guiding rod 205 away from the heat-conducting support plate 203, and finally drip downward into the nutrient substance 202, so as to increase the humidity in the nutrient substance 202.

[0045] like Figures 1-5 As shown, a drainage plate 214 is provided on one side of the heat-conducting support plate 203 to guide and discharge the liquefied and gathered water droplets, thereby preventing the water droplets from directly dripping into the nutrient 202 and increasing the humidity of the nutrient 202. The drainage plate 214 is provided with a plurality of air holes 215 and drainage grooves 216 to facilitate the discharge of liquefied water. A groove is provided on the inner wall of one side of the deodorizing tank body 1 close to the drainage plate 214 to receive the water flowing downward from the drainage groove 216.

[0046] like Figures 1-7 As shown, the spray purification mechanism 3 is installed under one of the support inclined plates 201. The spray purification mechanism 3 includes a support block 301. The support block 301 is provided with a spray chamber 302 and a spray chamber 303, both of which are used to transport the purification liquid. A plurality of spray heads 304 and spray nozzles 305 are installed on the support block 301. The spray head 304 is used to spray the purification liquid out, so that the waste gas and the essence liquid can be better contacted, thereby improving the purification effect of the waste gas. The plurality of spray nozzles 305 are all arranged on one side of the bottom of the support block 301, so that the spray nozzle 305 can only spray to one dispersing plate 312, thereby facilitating the simultaneous rotation of the plurality of dispersing plates 312.

[0047] like Figures 1-4As shown in the figure, a liquid pump 306 is installed on the main body 1 of the deodorization tank to provide power for the spraying of the purification liquid. A liquid delivery pipe 307 and a liquid suction pipe 308 are fixedly connected to the liquid pump 306, both of which are used to transport the purification liquid. Storage tanks 309 are arranged on both sides of the liquid delivery pipe 307, which are respectively used to store alkaline neutralizing liquid and acidic neutralizing liquid, so as to conveniently and quickly neutralize the pH value of the waste gas and provide a good environment for the purification of microorganisms. A communicating pipe 310 is fixedly connected between a pair of storage tanks 309 and the liquid delivery pipe 307 for transporting the neutralizing liquid.

[0048] Preferably, a pH value detector is arranged in the waste gas input pipe 101 to know the pH value of the waste gas, so as to conveniently open the storage tank 309 or the communicating pipe 310 to neutralize the waste gas and provide good conditions for the microbial purification treatment.

[0049] As Figures 1-7 shown in the figure, a column 311 is installed in the main body 1 of the deodorization tank to support a plurality of dispersion plates 312. A plurality of evenly distributed dispersion plates 312 are installed on the column 311 for discharging the waste gas, improving the contact effect between the waste gas and the purification liquid, and further improving the purification effect of the waste gas. A support bearing is fixedly connected between the plurality of dispersion plates 312 and the column 311.

[0050] During specific use, the waste gas is introduced into the fixed frame 103 through the waste gas input pipe 101, and then sprayed out from the one-way valve 106 through the transportation of the branch thin pipe 104 and the discharge pipe 105. Then, it passes through the clear water liquid, which not only purifies the waste gas for the first time, but also has a neutralizing effect, and increases the humidity of the waste gas. Then, the waste gas continues to float upward;

[0051] By starting the liquid pump 306, the external purification liquid is sucked into by the liquid suction pipe 308, and is first transported to the injection cavity 302 through the liquid delivery pipe 307, and then enters the spraying cavity 303, so that the purification liquid is first ejected from the injection nozzle 305, driving the dispersion plate 312 to rotate, and then sprayed out from a plurality of spray heads 304, so that the dispersion plate 312 discharges the waste gas, thereby improving the contact effect between the purification liquid and the waste gas;

[0052] Then the exhaust gas will pass above the nutrient 202. Through the reaction with microorganisms, the microorganisms will absorb the harmful substances in the exhaust gas. Finally, after being adsorbed and purified by the activated carbon adsorption plate 102, it can be discharged. Moreover, when the exhaust gas passes above the nutrient 202, it will contact the liquid guide rod 205 and the sliding liquid guide plate 204 with lower temperature, which will cause the water vapor in the exhaust gas to be liquefied. Then, it will drip downward through the liquid guide rod 205 into the microorganisms in the nutrient 202, improving the living environment of the microorganisms, and thus facilitating the maintenance of the activity of the microorganisms. And when the humidity of the nutrient 202 is within the appropriate range, the driving motor 209 will drive the transmission support shaft 208 to rotate, which will cause the rotating push block 210 to push the sliding liquid guide plate 204 to slide, making one side of the sliding liquid guide plate 204 flush with the liquid guide rod 205. At this time, the water droplets generated by liquefaction will slide downward into the drainage groove 216 and then be discharged, preventing the water droplets from easily dripping onto the nutrient 202, thus maintaining the humidity within the appropriate range and facilitating the maintenance of the activity of the microorganisms.
