[0002] In modern industrial production, industries such as printing and painting, as important components of the national economy, the problem of waste gas generated during their production processes is becoming increasingly severe. The waste gas emitted by such industries has the remarkable characteristics of low concentration, large air volume, and complex composition. The pollutant concentration is usually lower than 100mg / m 3 , while the emission air volume exceeds 100,000 m 3 / h, which also contains volatile organic compounds such as benzene series, esters, and ketones. These waste gases not only pollute the atmospheric environment but also endanger human health, causing problems such as respiratory diseases and nervous system damage.

[0003] For the treatment of such waste gases, there are many drawbacks in traditional technical means. The current combined treatment process has problems of residual dirt purification and lack of energy utilization at the system level, resulting in unstable overall treatment efficiency. Therefore, developing a combined waste gas collection and filtration device that can achieve efficient cooperation of multiple units has become the key to breaking through the difficult problem of treating low-concentration and large-air-volume waste gases.

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] An environment-friendly combined waste gas collection and filtration device. In an embodiment of the present invention, as Figure 1 and Figure 2 shown, it includes: an intake air nozzle; a pre-filter assembly, the pre-filter assembly is connected and communicated with the intake air nozzle; a spray pretreatment device, the spray pretreatment device is connected and communicated with the pre-filter assembly for filtering water-soluble dirt; a self-cleaning component, the self-cleaning component is connected to the inside of the spray pretreatment device; a concentration absorption device, the concentration absorption device is connected and communicated with the side of the spray pretreatment device far from the intake air nozzle; wherein, the concentration absorption device includes: a rotary adsorption device, the rotary adsorption device is connected and communicated with the side of the spray pretreatment device far from the intake air nozzle for filtering non-water-soluble dirt; a membrane separation absorption device, the membrane separation absorption device is connected to the rotary adsorption device for separating residual non-water-soluble dirt.

[0024] In an embodiment of the present invention:

[0025] As Figures 1 to 3As shown in the figure, the pre-filtering component 2 includes: a first guiding bin 201, which is communicated with the intake air nozzle 1; an expansion bin 202, which is communicated with one end of the first guiding bin 201 away from the intake air nozzle 1; a dirt collection ring bin 203, which is communicated with one end of the expansion bin 202 away from the first guiding bin 201; a dirt collection groove 204, which is arranged inside the dirt collection ring bin 203; a sewage discharge control part 205, which is communicated with the bottom side of the dirt collection ring bin 203; the sewage discharge control part 205 is selected as an electromagnetic valve;

[0026] When the device is arranged at the exhaust gas sewage outlet and the exhaust gas is collected and filtered, the concentration absorption device 5 is turned on, and a negative pressure air flow can be formed in the direction from the intake air nozzle 1, the expansion bin 202, the dirt collection ring bin to the concentration absorption device 5. The exhaust gas enters the device through the above direction. First, the spray pretreatment device 3 filters out the dust, liquid pollutants and part of water-soluble substances in the exhaust gas, so as to avoid the blockage of the subsequent rotary adsorption device 6 and the membrane separation absorption device 7. At this time, there are still non-water-soluble VOCs (such as benzene, toluene) and other pollutants in the exhaust gas entering the concentration absorption device 5. Then, the concentration absorption device 5 first enriches and concentrates the non-water-soluble pollutants, converts the low-concentration exhaust gas into a high-concentration air flow and then processes it through the membrane separation absorption device 7. When processing through the membrane separation absorption device 7, by using the "gas selective permeation" characteristic of the hydrophobic membrane pores, the exhaust gas flows on the outer side of the membrane, and the ionic liquid flows on the inner side of the membrane. The membrane pores only allow gas molecules to pass through, and the liquid is blocked by the surface tension, so as to realize the separation of the residual non-water-soluble pollutants. When the device is temporarily out of use, the internal cleaning of the expansion bin 202 and the dirt collection ring bin 203 can be carried out through the built-in self-cleaning component 4. After the cleaning is completed, the sewage discharge control part 205 can be opened to discharge the dirt gathered by the cleaning in a directional manner.

[0027] In an embodiment of the present invention:

[0028] Such as Figure 1 And Figure 2 As shown in the figure, the spray pretreatment device 3 includes: a liquid storage tank 301, which is connected with the first guiding bin 201; a conduction bin 302, which is communicated with the liquid storage tank 301; a graded spray pipe bin 303, which is fixedly connected with the expansion bin 202 through penetration; a connection control part 304, one side of which is communicated with the conduction bin 302 and the other side of which is communicated with the graded spray pipe bin 303; the connection control part 304 is selected as a micro electric control pump;

[0029] Inside the liquid storage tank 301, there is stored water body, weakly alkaline additives, and functional additives. The weakly alkaline additives can filter acidic gases, and the functional additives can enhance the dissolution ability of weakly polar VOCs by reducing the surface tension of droplets. The graded spray pipe bin 303 is arranged in a three-level stepped manner. The waste gas entering the inside of the expansion bin 202 horizontally cross-flows through the spray area at the bottom of the graded spray pipe bin 303. The graded spray pipe bin 303 arranged in a three-level stepped manner is perpendicular to the air flow direction, forming a three-level treatment gradient of "pre-washing - fine-washing - diversion", maximizing the gas-liquid contact area and prolonging the contact time. The pre-washing layer removes large particle dust and absorbs high-concentration water-soluble pollutants, thereby reducing the subsequent fine-washing load; the fine-washing layer captures fine dust and deeply absorbs medium- and low-concentration water-soluble VOCs, strengthening gas-liquid mass transfer; the diversion layer guides the waste gas to evenly enter the subsequent concentration absorption device 5, reducing eddy currents and pressure drops, and capturing escaping fine dust.

[0030] In one embodiment of the present invention:

[0031] As Figure 1 shown, the self-cleaning component 4 includes: a first support shaft seat 401, the first support shaft seat 401 is connected to one side of the runner adsorption device 6 close to the dirt collection ring bin 203; a first driving member 402, the first driving member 402 is connected to the middle of the first support shaft seat 401; the first driving member 402 is selected as an electric shaft seat; a linkage shaft 403, the linkage shaft 403 is connected to the first driving member 402; a transmission rod 404, the transmission rod 404 is connected to the linkage shaft 403 and is arranged inside the dirt collection ring bin 203; a cleaning brush 405, the cleaning brush 405 is connected to one end of the transmission rod 404 away from the linkage shaft 403 and abuts against the bottom surface of the dirt collection tank 204;

[0032] When collecting and treating waste gas, the positions of the transmission rod 404 and the cleaning brush 405 are as Figure 1 shown. The water-soluble dirt and large particle impurities filtered by the spray pretreatment device 3 can be introduced into the dirt collection tank 204 inside the dirt collection ring bin 203 through the expansion bin 202. When performing internal self-cleaning, the first driving member 402 drives the linkage shaft 403 and the transmission rod 404 to rotate, synchronously driving the cleaning brush 405 to rotate axially. The axially rotating cleaning brush 405 can clean the dirt attached inside the dirt collection tank 204. The cleaned dirt accumulates on the bottom side of the dirt collection tank 204. After cleaning, the transmission rod 404 and the cleaning brush 405 are reset to Figure 1 the position shown, and the sewage discharge control member 205 can be opened to discharge the dirt;

[0033] In this application, the first driving member 402 is not limited to an electric shaft seat. It can also adopt a linear motor, an electric cylinder, or a cylinder drive, etc., as long as it can realize the rotational adjustment of the linkage shaft 403. Specific limitations are not made here.

[0034] In one embodiment of the present invention:

[0035] As Figure 1 shown, the self-cleaning component 4 further includes: a second bracket shaft seat 406, and the second bracket shaft seat 406 is connected to one side of the interior of the expansion bin 202 close to the first guide bin 201; a cleaning member 407, one end of the cleaning member 407 is connected to the second bracket shaft seat 406, and the other end is connected to the end of the linkage shaft 403 away from the first driving member 402; the cleaning member 407 is a multi-control high-pressure spray pipe.

[0036] When the linkage shaft 403 rotates, it can drive the cleaning member 407 to rotate synchronously. The cleaning member 407 is connected to the liquid storage tank 301 through a built-in hose (not shown in the figure) to supply cleaning liquid agent to the cleaning member 407. The waste gas introduced into the interior of the expansion bin 202 in the early stage contains more impurities and is easy to accumulate and adhere to the inner wall of the expansion bin 202. When the cleaning member 407 is turned on and rotates with the linkage shaft 403, it can spray and clean the inner wall of the expansion bin 202 under high pressure through a number of external holes, and the sewage generated by the cleaning can be diverted into the sewage collection ring bin 203.

[0037] In one embodiment of the present invention:

[0038] As Figures 1 to 4 shown, the rotary adsorption device 6 includes: a second guide bin 601, and the second guide bin 601 is connected to the side of the sewage collection ring bin 203 away from the expansion bin 202; an adsorption and concentration bin 602, and the adsorption and concentration bin 602 is connected to the side of the second guide bin 601 away from the sewage collection ring bin 203; a second driving member 603, and the second driving member 603 is connected to the adsorption and concentration bin 602; the second driving member 603 is an electric rotating shaft; a wheel frame 604, the wheel frame 604 is arranged inside the adsorption and concentration bin 602 and is connected to the second driving member 603; a number of concentration and screening members 609, a number of concentration and screening members 609 are arranged inside the wheel frame 604; the concentration and screening member 609 is a zeolite molecular sieve; a heating member 605, and the heating member 605 is connected to the adsorption and concentration bin 602; the heating member 605 is an electric heating blower; a heat supply pipe 606, one end of the heat supply pipe 606 is connected to the heating member 605, and the other end is connected to the adsorption and concentration bin 602; a cooling member 607, and the cooling member 607 is connected to the side of the adsorption and concentration bin 602 away from the heating member 605; the cooling member 607 is an axial flow fan; a cooling pipe 608, one end of the cooling pipe 608 is connected to the cooling member 607, and the other end is connected to the adsorption and concentration bin 602.

[0039] The heating component 605 and the cooling component 607 operate continuously. Heat flow gas and normal temperature gas can be provided to the concentration and screening component 609 through the heat supply pipe 606 and the cooling pipe 608 that penetrate the adsorption and concentration bin 602 directionally. The second driving component 603 can drive the wheel frame 604 to rotate periodically in the adsorption and concentration bin 602. When the waste gas filtered by the spray pretreatment device 3 enters the interior of the second guiding bin 601, the waste gas can contact the concentration and screening component 609 in the tangential direction of the wheel frame 604. The VOCs molecules in the waste gas are captured by the zeolite micropores. When the concentration and screening component 609 containing VOCs molecules rotates periodically to the area of the heat supply pipe 606 and contacts the heat flow gas, the VOCs desorb from the zeolite surface due to the increase in temperature, forming a high-concentration gas flow with a concentration 10 - 20 times higher. The membrane separation and absorption device 7 is arranged on the side of the adsorption and concentration bin 602 connected to the heat supply pipe 606. Under the action of negative pressure, the high-concentration gas flow is introduced into the interior of the membrane separation and absorption device 7. When the concentration and screening component 609 that desorbs the high-concentration gas flow rotates to the position of the bottom cooling pipe 608 and contacts the normal temperature gas, the concentration and screening component 609 returns to the optimal adsorption state through the cooling of the normal temperature gas. Several concentration and screening components 609 cycle through the above process to complete a full operation cycle.

[0040] In an embodiment of the present invention:

[0041] As Figure 1 and Figure 5 shown, the membrane separation and absorption device 7 includes: a negative pressure pipe 701, which is connected to the side of the adsorption and concentration bin 602 away from the heat supply pipe 606; a transfer bin 702, which is connected to the top side of the adsorption and concentration bin 602 and is connected to the end of the negative pressure pipe 701 away from the adsorption and concentration bin 602; a negative pressure component 703, which is connected to the transfer bin 702; the negative pressure component 703 is selected as a negative pressure fan pipe group; a separation membrane component 704, which is connected to the end of the negative pressure component 703 away from the transfer bin 702; the separation membrane component 704 is selected as a hollow limiting membrane group; an exhaust air nozzle 705, which is connected to the bottom side of the separation membrane component 704;

[0042] When the negative pressure component 703 operates, negative pressure can be formed inside the negative pressure pipe 701, the transfer bin 702 and the front components, and the waste gas processed by the rotating wheel adsorption device 6 is introduced into the separation membrane component 704. Membrane separation coupling ionic liquid absorption is carried out through the separation membrane component 704. The separation membrane component 704 includes a hydrophobic microporous membrane and a lipophilic ionic liquid. The waste gas flows on the outer side of the membrane, and the ionic liquid flows on the inner side of the membrane. Only gas molecules are allowed to pass through the membrane pores, and the liquid is blocked by surface tension. A VOCs partial pressure difference is formed on both sides of the membrane, which promotes the diffusion of VOCs from the gas phase through the membrane pores to the liquid phase, thereby realizing the separation of residual water-insoluble dirt.

[0043] The working principle of the present invention is as follows: The device is installed at the exhaust gas discharge port. When collecting and filtering exhaust gas, the concentration absorption device 5 is turned on, and a negative pressure air flow can be formed from the intake air nozzle 1 to the expansion chamber 202, the sewage collection ring chamber 203, and in the direction of the concentration absorption device 5. The exhaust gas enters the device through the above direction. First, the spray pretreatment device 3 filters out dust, liquid pollutants, and some water-soluble substances in the exhaust gas, thereby avoiding blockage of the subsequent rotary adsorption device 6 and the membrane separation absorption device 7. At this time, non-water-soluble VOCs (such as benzene and toluene) and other pollutants still remain in the exhaust gas entering the concentration absorption device 5. Then, the concentration absorption device 5 first enriches and concentrates the non-water-soluble pollutants, converts the low-concentration exhaust gas into a high-concentration air flow, and then processes it through the membrane separation absorption device 7. When processing through the membrane separation absorption device 7, using the "gas selective permeation" characteristic of the hydrophobic membrane pores, the exhaust gas flows on the outside of the membrane, and the ionic liquid flows on the inside of the membrane. Only gas molecules are allowed to pass through the membrane pores, and the liquid is blocked by surface tension, thereby realizing the separation of residual non-water-soluble pollutants. When the device is temporarily out of use, the internal cleaning of the expansion chamber 202 and the sewage collection ring chamber 203 can be carried out through the built-in self-cleaning component 4. After the cleaning is completed, the sewage discharge control part 205 can be opened to direct the discharged sewage. Water, weak alkaline additives, and functional additives are stored inside the liquid storage tank 301. The weak alkaline additives can filter acidic gases, and the functional additives can enhance the dissolution ability of weakly polar VOCs by reducing the surface tension of the liquid droplets. The hierarchical spray pipe chamber 303 is arranged in a three-stage stepped shape. The exhaust gas entering the expansion chamber 202 horizontally cross-flows through the bottom spray area of the hierarchical spray pipe chamber 303. The three-stage stepped hierarchical spray pipe chamber 303 is perpendicular to the air flow direction, forming a three-stage treatment gradient of "pre-washing - fine-washing - guiding", maximizing the gas-liquid contact area and prolonging the contact time. The pre-washing layer removes large particle dust and absorbs high-concentration water-soluble pollutants, thereby reducing the subsequent fine-washing load; the fine-washing layer captures fine dust and deeply absorbs medium and low-concentration water-soluble VOCs, strengthening gas-liquid mass transfer; the guiding layer guides the exhaust gas to evenly enter the subsequent concentration absorption device 5, reducing eddy currents and pressure drops, and capturing escaping fine dust.

[0044] When collecting and treating exhaust gas, the positions of the transmission rod 404 and the cleaning brush 405 are as Figure 1 shown. The water-soluble pollutants and large particle impurities filtered out by the spray pretreatment device 3 can be introduced into the sewage collection tank 204 inside the sewage collection ring chamber 203 through the expansion chamber 202. When performing internal self-cleaning, the first driving part 402 drives the linkage shaft 403 and the transmission rod 404 to rotate, synchronously driving the cleaning brush 405 to rotate axially. The axially rotating cleaning brush 405 can clean the dirt attached inside the sewage collection tank 204. The cleaned dirt accumulates at the bottom side of the sewage collection tank 204. After the cleaning is completed, the transmission rod 404 and the cleaning brush 405 are reset to Figure 1At the position shown, the sewage control member 205 can be opened for sewage discharge. The first driving member 402 is not limited to an electric shaft seat. A linear motor, an electric cylinder, a cylinder drive, etc. can also be used, as long as the rotation adjustment of the linkage shaft 403 can be achieved, and no specific limitation is made here. When the linkage shaft 403 rotates, the cleaning member 407 can be driven to rotate synchronously. The cleaning member 407 is connected to the liquid storage tank 301 through a built-in hose (not shown in the figure) to supply cleaning liquid agent to the cleaning member 407. The waste gas introduced into the expansion chamber 202 in the early stage contains more impurities and is easy to accumulate and adhere to the inner wall of the expansion chamber 202. When the cleaning member 407 is turned on and rotates with the linkage shaft 403, high-pressure spraying cleaning can be carried out on the inner wall of the expansion chamber 202 through a number of external holes. The sewage generated by the cleaning can be guided into the sewage collection ring chamber 203. The heating member 605 and the cooling member 607 operate continuously, and heat flow gas and normal temperature gas can be provided for the concentration and screening member 609 through the heating pipe 606 and the cooling pipe 608 penetrating the adsorption and concentration chamber 602 in a targeted manner. The second driving member 603 can drive the wheel frame 604 to rotate periodically in the adsorption and concentration chamber 602. When the waste gas filtered by the spray pretreatment device 3 enters the second guiding chamber 601, the waste gas can contact the concentration and screening member 609 in the tangential direction of the wheel frame 604, and the VOCs molecules in the waste gas are captured by the zeolite micropores. When the concentration and screening member 609 containing VOCs molecules rotates periodically to the area of the heating pipe 606 and contacts the heat flow gas, the VOCs are desorbed from the zeolite surface due to the temperature rise, forming a high-concentration gas stream concentrated by 10-20 times. The membrane separation and absorption device 7 is arranged on the side of the adsorption and concentration chamber 602 opposite to the connection of the heating pipe 606. Under the action of negative pressure, the high-concentration gas stream is introduced into the interior of the membrane separation and absorption device 7. When the concentration and screening member 609 desorbing the high-concentration gas stream rotates to the position of the bottom cooling pipe 608 and contacts the normal temperature gas, the concentration and screening member 609 returns to the optimal adsorption state through the cooling of the normal temperature gas. A number of concentration and screening members 609 cycle through the above process to complete a complete operation cycle. When the negative pressure member 703 operates, a negative pressure can be formed in the negative pressure pipe 701, the transfer chamber 702 and the front-end components, and the waste gas treated by the rotary wheel adsorption device 6 is introduced into the separation membrane member 704, and membrane separation coupling ionic liquid absorption is carried out through the separation membrane member 704. The separation membrane member 704 includes a hydrophobic microporous membrane and a lipophilic ionic liquid. The waste gas flows on the outer side of the membrane, and the ionic liquid flows on the inner side of the membrane. Only gas molecules are allowed to pass through the membrane pores, and the liquid is blocked by surface tension, forming a VOCs partial pressure difference on both sides of the membrane, which promotes the diffusion of VOCs from the gas phase through the membrane pores to the liquid phase, so as to achieve the separation of residual water-insoluble dirt.

[0045] In summary, through the three-stage stepped spray pretreatment, dust and water-soluble pollutants are efficiently filtered to avoid clogging of subsequent devices; the combination of concentration absorption and rotary wheel adsorption converts low-concentration waste gas into high-concentration gas flow to improve the treatment efficiency; the membrane separation is coupled with ionic liquid absorption to achieve the separation of residual water-insoluble contaminants, further improving the overall stability of waste gas treatment.

[0046] In addition, it should be understood that although this specification is described according to embodiments, not each embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
