Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a catalytic combustion industrial waste gas treatment device. Background Technology

[0002] Catalytic combustion takes place in a catalytic combustion device. Organic waste gas is first preheated by a heat exchanger and then enters the combustion chamber. When passing through the catalyst bed, hydrocarbon molecules and oxygen molecules in the mixed gas are adsorbed on the surface of the catalyst and activated. Because surface adsorption lowers the activation energy of the reaction, hydrocarbons and oxygen molecules are rapidly oxidized at a lower temperature to produce carbon dioxide and water, which are then discharged, thus achieving the purpose of treating waste gas. In addition, industrial waste gas is usually filtered before catalytic combustion to remove impurities and improve the efficiency of the catalytic combustion reaction.

[0003] A search revealed that the document with publication number "CN216799110U" mentions that "this application belongs to the field of waste gas treatment technology and discloses a catalytic combustion waste gas treatment device, including a shell, a filter plate fixedly installed on the inner wall of the shell, a vibrator provided on one side of the filter plate, the vibrator being located inside the shell, and a lever arm provided at the end of the vibrator facing the filter plate, a contact block provided at one end of the lever arm, a fixing plate provided at the bottom of the vibrator, the bottom of the fixing plate being fixedly connected to the inner wall of the bottom of the shell, a through groove opened at the bottom of the shell, the through groove being located on the side of the filter plate away from the bottom of the vibrator, and an inclined plate provided on one side of the top of the through groove, the side wall of the inclined plate being fixedly connected to the inner wall of the shell." This device filters the waste gas entering the shell through the filter plate, and, in conjunction with the activated carbon plate, effectively adsorbs and purifies the filtered waste gas. However, this device, using only a single filter plate, can only remove solid particles from the waste gas; a large amount of dust and impurities remain in the flowing waste gas, leading to uneven catalytic combustion in the subsequent process.

[0004] Therefore, we provide a catalytic combustion industrial waste gas treatment device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a catalytic combustion industrial waste gas treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a catalytic combustion industrial waste gas treatment device, comprising a treatment tank, an air inlet pipe installed at the top of the treatment tank, an adsorption filter assembly installed inside the treatment tank, a water collection tank provided at the bottom of the treatment tank, and a drain pipe provided on the right side of the water collection tank.

[0007] The adsorption filtration assembly includes a filter plate installed inside the treatment tank, an installation frame below the filter plate, an adsorption plate inside the installation frame, and an atomizing nozzle installed on the upper inner wall of the installation frame.

[0008] Preferably, the filter plate is provided in three sets, and the filter mesh diameter of the filter plate decreases sequentially.

[0009] Preferably, the mounting frame is provided in two sets, the adsorption plate has a mesh structure, and the adsorption plate is made of high-temperature resistant sponge material.

[0010] Preferably, a water inlet pipe is provided on the right side of the treatment tank, a diversion pipe is installed on the right side of the mounting frame, the diversion pipe is connected to the water inlet pipe, and the atomizing nozzle is connected to the diversion pipe.

[0011] Preferably, a connecting plate is provided at the inner right end of the water collection tank, and the opening height of the drain pipe is higher than the lower edge height of the connecting plate.

[0012] Preferably, an exhaust pipe is provided on the left side of the water collection tank, and the height of the exhaust pipe is higher than the height of the drain pipe.

[0013] Preferably, the left end of the exhaust pipe is fixedly connected to a drying tank, and a drying plate is installed on the inner side of the drying tank. The drying plate is made of activated carbon.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Industrial waste gas is filtered in multiple stages through three sets of filter plates to improve the removal of particulate impurities. Dust impurities in the waste gas are adsorbed by the adsorption plates. At the same time, water is sent into the water inlet pipe by an external water pump and then sprayed on the adsorption plates through atomizing nozzles, thereby reducing the dust content in the waste gas and wetting the adsorption plates to improve the adsorption effect of dust. When not in use, water mist can be continuously sprayed inside to clean the adsorption plates and filter plates, improving the long-term performance of both.

[0016] 2. Water sprayed into the treatment tank is collected through a water collection tank and discharged through a drain pipe. At the same time, a connecting plate is used on both sides to form a connecting structure to block the exhaust gas and prevent it from being discharged from the drain pipe. The filtered exhaust gas is discharged through an exhaust pipe, which is set higher than the drain pipe to prevent water from being discharged from the exhaust pipe. Then, the discharged industrial exhaust gas is dried through a drying plate to ensure the full reaction of the subsequent catalytic combustion of the exhaust gas. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 As shown, a catalytic combustion industrial waste gas treatment device includes a treatment tank 1, an air inlet pipe 2 installed at the top of the treatment tank 1, an adsorption filter assembly 3 installed inside the treatment tank 1, a water collection tank 4 provided at the bottom of the treatment tank 1, and a drain pipe 6 provided on the right side of the water collection tank 4.

[0024] The adsorption filtration assembly 3 includes a filter plate 301 installed inside the treatment tank 1, an installation frame 302 is provided below the filter plate 301, an adsorption plate 303 is provided inside the installation frame 302, and an atomizing nozzle 306 is installed on the upper side of the inner wall of the installation frame 302.

[0025] Furthermore, the filter plate 301 is provided in three sets, with the filter screen pore size of the filter plate 301 decreasing sequentially. The industrial waste gas is filtered in multiple stages through the three sets of filter plates 301, thereby improving the effect of removing particulate impurities.

[0026] Furthermore, the mounting frame 302 is provided with two sets of adsorption plates 303, which have a mesh structure and are made of high-temperature resistant sponge material. The adsorption plates 303 adsorb dust and impurities in the exhaust gas to ensure the effect of subsequent catalytic combustion.

[0027] Furthermore, a water inlet pipe 304 is installed on the right side of the treatment tank 1, and a diversion pipe 305 is installed on the right side of the mounting frame 302. The diversion pipe 305 is connected to the water inlet pipe 304, and the atomizing nozzle 306 is connected to the diversion pipe 305. Water is sent into the water inlet pipe 304 through an external water pump, and then sprayed onto the adsorption plate 303 through the atomizing nozzle 306, thereby reducing the dust content in the exhaust gas and wetting the adsorption plate 303 to improve the dust adsorption effect. Moreover, when not in use, water mist can be continuously sprayed into the adsorption plate 303 and the filter plate 301 to clean them, improving the long-term use effect of both.

[0028] Furthermore, a connecting plate 5 is provided on the inner right end of the water collection tank 4, and the opening height of the drain pipe 6 is higher than the lower edge of the connecting plate 5. The water sprayed into the treatment tank 1 is collected through the water collection tank 4 and discharged through the drain pipe 6. At the same time, the connecting plate 5 forms a communicating vessel structure on both sides, thereby blocking the exhaust gas and preventing the exhaust gas from being discharged from the drain pipe 6.

[0029] Furthermore, an exhaust pipe 7 is provided on the left side of the water collection tank 4. The height of the exhaust pipe 7 is higher than that of the drain pipe 6. The filtered exhaust gas is discharged through the exhaust pipe 7, and the higher position of the exhaust pipe 7 prevents water from being discharged from the exhaust pipe 7.

[0030] Furthermore, the left end of the exhaust pipe 7 is fixedly connected to the drying tank 8, and a drying plate 9 is installed on the inner side of the drying tank 8. The drying plate 9 is made of activated carbon. The industrial waste gas is dried by the drying plate 9 to ensure the effect of subsequent catalytic combustion of the waste gas.

[0031] Working Principle: In use, firstly, the device is installed at the desired location. Then, the waste gas requiring catalytic combustion treatment is introduced into the treatment tank 1. Subsequently, the industrial waste gas undergoes multi-stage filtration through three sets of filter plates 301, improving the removal of particulate impurities. Secondly, dust impurities in the waste gas are adsorbed by the adsorption plates 303. Simultaneously, water is pumped into the inlet pipe 304 via an external water pump, and then sprayed onto the adsorption plates 303 through atomizing nozzles 306, thereby reducing the dust content in the waste gas and wetting the adsorption plates 303 to improve dust adsorption. Even when not in use, water mist can be continuously sprayed into the adsorption tank to further enhance the adsorption effect. The first step involves cleaning plate 303 and filter plate 301 to improve their long-term performance. The second step involves collecting water sprayed into the treatment tank 1 through the water collection tank 4 and discharging it through the drain pipe 6. At the same time, the connecting plate 5 forms a connecting structure on both sides to block the exhaust gas and prevent it from being discharged from the drain pipe 6. The third step involves discharging the filtered exhaust gas through the exhaust pipe 7. The exhaust pipe 7 is positioned higher than the drain pipe 6 to prevent water from being discharged from it. The discharged industrial exhaust gas is then dried through the drying plate 9 to ensure a full reaction in the subsequent catalytic combustion of the exhaust gas. This completes the use of a catalytic combustion industrial exhaust gas treatment device.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
