[0002] Organic waste gas treatment refers to the use of a series of methods and technologies to harmlessly treat waste gas containing organic compounds generated in industrial production, daily life and other activities to reduce the impact on the environment and human health.

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0024] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example

[0025] like Figure 1-Figure 6As shown, a catalytic oxidation device for organic waste gas comprises: a plant main body 1, a treatment box 2 installed on one side of the outer end of the plant main body 1, a waste gas pipe 3 installed between the treatment box 2 and the plant main body 1, and a clean air component arranged inside the treatment box 2, for catalytically oxidizing the organic waste gas generated in the plant main body 1, the clean air component comprises: a waste gas collection chamber 201, an adsorption chamber 202, a concentration chamber 203, a catalytic decomposition chamber 204 and a connecting pipe a205. After the organic waste gas is adsorbed, condensed and concentrated by the clean air component, and catalytically oxidized, the catalytic reaction generates carbon dioxide and water, which can thoroughly treat the organic waste gas without generating secondary pollutants, thereby protecting the environment and reducing the cost of waste gas treatment.

[0026] Among them, a waste discharge pipe 101 is installed at the top of the interior of the plant body 1, a draft fan a102 is installed at the outer end of the waste discharge pipe 101, and one end of the waste gas pipe 3 passes through the interior of the plant body 1 and is connected to the draft fan a102, a waste gas collecting chamber 201 connected to the waste gas pipe 3 is installed on one side of the interior of the treatment box 2, an adsorption chamber 202 is installed on one side of the waste gas collecting chamber 201, and an activated carbon adsorption plate is arranged inside the adsorption chamber 202, a concentration chamber 203 is installed on one side of the adsorption chamber 202, a catalytic decomposition chamber 204 is installed on one side of the concentration chamber 203, and connecting pipes a205 are installed between the catalytic decomposition chamber 204, the concentration chamber 203, the adsorption chamber 202 and the waste gas collecting chamber 201.

[0027] When the coating process is carried out inside the main body of the factory building 1, the production line is generally equipped with a waste discharge pipe 101, and the organic waste gas generated by the coating process is collected in the waste discharge pipe 101, and the organic waste gas inside the waste discharge pipe 101 is extracted to the waste gas pipe 3 through the induced draft fan a102, and discharged into the waste gas collection chamber 201 inside the treatment box 2 through the waste gas pipe 3. Since connecting pipes a205 are installed between the catalytic decomposition chamber 204, the concentration chamber 203, the adsorption chamber 202 and the waste gas collection chamber 201, the organic waste gas can flow between the waste gas collection chamber 201, the adsorption chamber 202, the concentration chamber 203 and the catalytic decomposition chamber 204 through the connecting pipe a205. When the organic waste gas in 01 is discharged into the adsorption chamber 202, the organic waste gas is adsorbed and treated by the activated carbon adsorption plate in the adsorption chamber 202, and the activated carbon is used to capture and remove organic compounds in the waste gas. When it is discharged into the concentration chamber 203, the temperature of the organic waste gas is reduced to condense the organic matter into liquid, thereby achieving organic concentration, which is convenient for enriching the organic matter concentrated into liquid. After being discharged into the catalytic decomposition chamber 204, since the catalytic decomposition chamber 204 is provided with a catalyst, the organic waste gas is subjected to a catalytic oxidation reaction, and the catalytic reaction generates carbon dioxide and water, which can thoroughly treat the organic waste gas without generating secondary pollutants. While protecting the environment, it can also reduce the cost of waste gas treatment.

[0028] Among them, a refrigeration unit 206 is installed at the bottom end of the processing box 2, a compressor 207 is installed on one side of the refrigeration unit 206, a cold air pipe 208 is installed between the refrigeration unit 206 and the concentration chamber 203, a waste pipe a4 is installed on one side of the bottom of the processing box 2, a connecting pipe b401 connected to the concentration chamber 203 is installed on the top of the waste pipe a4, the bottom of the waste pipe a4 is connected to the collecting box 402 through a branch pipe, a liquid inlet pipe 403 is installed on one side of the top of the collecting box 402, a liquid outlet pipe a404 is installed on one side of the bottom of the collecting box 402, and the outer ends of the liquid inlet pipe 403 and the liquid outlet pipe a404 are both threadedly connected with sealing covers.

[0029] When the organic waste gas is in the adsorption chamber 202, it is adsorbed by the activated carbon adsorption plate and discharged into the concentration chamber 203. At this time, the refrigeration unit 206 and the compressor 207 start to work. The refrigeration unit 206 and the compressor 207 are connected by a conduit. After the refrigeration unit 206 generates cold air, it is discharged from the cold air pipe 208 into the concentration chamber 203, so that the cold air contacts the organic waste gas, and then cools the organic waste gas, condenses the organic matter into liquid, and achieves the concentration of the organic matter. The liquid is discharged from the connecting pipe b401 to the waste pipe a4, and then discharged to the collecting box 402 through the branch pipe. The sealing cover at the top of the liquid inlet pipe 403 is turned open, and a catalytic solvent is added from the liquid inlet pipe 403 to allow the catalytic solvent to contact and react with the condensed liquid. The catalytic reaction generates carbon dioxide and water. The catalytic solvent is a catalytic solvent for treating organic waste gas. After the reaction is completed, the sealing cover at the outer end of the liquid outlet pipe a404 is turned open, and the reactants in the collecting box 402 are discharged from the liquid outlet pipe a404.

[0030] Among them, an induced draft fan b6 is installed on one side of the outer end of the processing box 2, and an air inlet pipe 601 connected to the catalytic decomposition chamber 204 is installed at the bottom of the induced draft fan b6, and a solenoid valve 602 is installed on the air inlet pipe 601, an exhaust pipe b704 is installed between the hot air pipe 701 and the catalytic decomposition chamber 204, and a high-temperature solenoid valve b705 is installed on the exhaust pipe b704, a waste pipe b5 is installed at one end of the waste pipe a4, a connecting pipe c501 is installed on one side of the top of the waste pipe b5, an exhaust fan 502 is installed at one end of the waste pipe b5, an exhaust pipe 503 is installed on the top of the exhaust fan 502, and a liquid outlet pipe b504 is installed at the bottom of the waste pipe b5.

[0031] When the organic waste gas is in the concentration chamber 203, it is condensed and enriched and then discharged into the catalytic decomposition chamber 204. At this time, the induced draft fan b6 and the solenoid valve 602 are started. Since the air inlet pipe 601 passes through the treatment box 2 and is connected to the catalytic decomposition chamber 204, the induced draft fan b6 inhales air from the air inlet pipe 601 into the catalytic decomposition chamber 204, and the hot air blower 7 is started. After the air is inhaled, the air is heated and transported to the exhaust pipe b704 through the hot air pipe 701. The high-temperature solenoid valve b705 is opened to send the hot air into the catalytic decomposition chamber 204 to heat the catalyst inside it, and there is enough The reaction oxygen can then be used to catalyze the oxidation reaction of the organic waste gas. Since the connecting pipe c501 is connected to the bottom end of the catalytic decomposition chamber 204, the carbon dioxide and water generated by the catalytic reaction are discharged from the connecting pipe c501 into the waste pipe b5. After the exhaust fan 502 at the outer end of the waste pipe b5 works, it evacuates the waste pipe b5, extracts the carbon dioxide gas, and discharges it into the exhaust pipe 503 for discharge. The water in the waste pipe b5 can be discharged to the sewer from the liquid outlet pipe b504, or the discharged water can be collected and reused in a container.

[0032] Among them, a hot air blower 7 is installed on the side of the outer end of the processing box 2 close to the factory body 1, a hot air pipe 701 is installed on one side of the hot air blower 7, an exhaust pipe a702 is installed between the hot air pipe 701 and the adsorption chamber 202, and a high-temperature solenoid valve a703 is installed on the exhaust pipe a702.

[0033] After the activated carbon adsorption plate in the adsorption chamber 202 has been adsorbed, its hot air blower 7 starts to work, and after sucking in air, it heats the air and transports it to the exhaust pipe a702 through the hot air pipe 701. The high-temperature solenoid valve a703 is opened to send hot air into the adsorption chamber 202, and the temperature of the activated carbon adsorption plate is increased, so that the organic molecules adsorbed on the surface of the adsorbent are separated from the adsorbent, so as to restore the adsorption capacity of the adsorbent.

[0034] A support rod 8 is installed on the outside of the exhaust pipe 503 , and a connecting ring 801 which is sleeved with the exhaust pipe 503 is installed on one side of the top of the support rod 8 .

[0035] When the exhaust pipe 503 and the exhaust fan 502 are installed and used, the exhaust pipe 503 is first inserted into the connecting ring 801 and fixed with bolts. When the exhaust pipe 503 is installed on the top of the exhaust fan 502, the exhaust pipe 503 is auxiliary supported by the support rod 8 to increase the stability of the placement of the exhaust pipe 503.

[0036] Among them, a control box and a rain shield are installed at the outer end of the main body of the plant 1.

[0037] Working principle:

[0038] When the coating process is carried out inside the main body of the factory building 1, the production line is generally equipped with a waste discharge pipe 101, and the organic waste gas generated by the coating process is collected in the waste discharge pipe 101, and the organic waste gas inside the waste discharge pipe 101 is extracted to the waste gas pipe 3 through the induced draft fan a102, and discharged into the waste gas collection chamber 201 inside the treatment box 2 through the waste gas pipe 3. Since connecting pipes a205 are installed between the catalytic decomposition chamber 204, the concentration chamber 203, the adsorption chamber 202 and the waste gas collection chamber 201, the organic waste gas can flow between the waste gas collection chamber 201, the adsorption chamber 202, the concentration chamber 203 and the catalytic decomposition chamber 204 through the connecting pipe a205. When the organic waste gas in 01 is discharged into the adsorption chamber 202, the organic waste gas is adsorbed and treated by the activated carbon adsorption plate in the adsorption chamber 202, and the activated carbon is used to capture and remove organic compounds in the waste gas. When it is discharged into the concentration chamber 203, the temperature of the organic waste gas is reduced to condense the organic matter into liquid, thereby achieving organic concentration, which is convenient for enriching the organic matter concentrated into liquid. After being discharged into the catalytic decomposition chamber 204, since the catalytic decomposition chamber 204 is provided with a catalyst, the organic waste gas is subjected to a catalytic oxidation reaction, and the catalytic reaction generates carbon dioxide and water, which can thoroughly treat the organic waste gas without generating secondary pollutants. While protecting the environment, it can also reduce the cost of waste gas treatment.

[0039] The condensed liquid is discharged from the connecting pipe b401 to the waste pipe a4, and then discharged to the collecting box 402 through the branch pipe. The sealing cover at the top of the liquid inlet pipe 403 is rotated open, and a catalytic solvent is added from the liquid inlet pipe 403 to make the catalytic solvent contact and react with the condensed liquid. The catalytic reaction generates carbon dioxide and water. The catalytic solvent is a catalytic solvent for treating organic waste gas. After the reaction is completed, the sealing cover at the outer end of the liquid outlet pipe a404 is rotated open, and the reactants in the collecting box 402 are discharged from the liquid outlet pipe a404. Since the connecting pipe c501 is connected to the bottom end of the catalytic decomposition chamber 204, the carbon dioxide and water generated by the catalytic reaction are discharged from the connecting pipe c501 into the waste pipe b5. After the exhaust fan 502 at the outer end of the waste pipe b5 works, it evacuates the waste pipe b5, extracts the carbon dioxide gas, and discharges it into the exhaust pipe 503 for discharge. The water in the waste pipe b5 can be discharged from the liquid outlet pipe b504 to the sewer, or the discharged water can be collected and reused in a container.
