[0014] 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.

[0015] This utility model discloses a gas purification and neutralization device, comprising a housing 1 and a gas supply device 2 located outside the housing 1. The gas supply device 2 is connected to the lower end of the housing 1 via a gas supply pipe 21. The lower end of the housing 1 is a first chamber 3, and a second chamber 4 is connected above the first chamber 3. A first filter 41 is provided between the first chamber 3 and the second chamber 4. A third chamber 5 is connected above the second chamber 4, and a second filter 51 is provided between the second chamber 4 and the third chamber 5. A fourth chamber 6 is connected above the third chamber 5, and a neutralization solvent nozzle 62 is provided in the fourth chamber 6. Above the fourth chamber 6 is a demisting layer 7, and at the top of the demisting layer 7 is an exhaust pipe 71. Around the exhaust pipe 71 is a second sensor group 8. The filter material is a composite filter with a microporous membrane on the surface, with an accuracy of less than 2.5 micrometers, which can prevent clogging. The demisting layer 7 has a built-in cyclone demister with cyclone blades inside, which makes the gas rotate. The centrifugal force generated when the gas rotates can make the droplets throw towards the inner wall, while the gas will rise and be discharged. The second sensor group 8 includes, but is not limited to, a pressure sensor, a flow sensor, and a toxic gas sensor.

[0016] Two sets of first sensor groups 31 are installed on the side of the first chamber 3. The two sets of first sensor groups 31 are symmetrically installed on the side of the first chamber 3. A drain pipe 32 is provided at the bottom of the first chamber 3. The first sensor group includes, but is not limited to, a temperature sensor, a pressure sensor, and a pH sensor. The temperature sensor can detect the temperature of the gas initially entering the device. The pressure sensor can detect whether the gas pressure in the device is at a normal level and can be used to determine whether there is a blockage in the device. The pH sensor can be used to monitor whether there are corrosive substances in the gas. The drain pipe is used to discharge the neutralized solvent.

[0017] The second chamber 4 has a first maintenance manhole 42 on its lower side and a second maintenance manhole 43 on its upper side. The maintenance manholes facilitate the maintenance of the equipment and reduce the occurrence of failures.

[0018] The third chamber 5 is provided with a third maintenance manhole 52 on the lower side. The maintenance manhole can facilitate the maintenance of the equipment and reduce the occurrence of failures.

[0019] The fourth chamber 6 is provided with a fourth maintenance manhole 61 at its lower end. The maintenance manhole can facilitate the maintenance of the equipment and reduce the occurrence of failures.

[0020] In use, the gas supply device 2 is activated, and the gas to be purified is sent to the first chamber 3 of the housing 1 through the gas supply pipe 21. The gas undergoes cooling and initial particulate matter removal in the first chamber 3. The first sensor group includes, but is not limited to, a temperature sensor, a pressure sensor, and a pH sensor. The first sensor group 31 monitors gas parameters in real time to ensure the initial treatment effect. The gas rises and passes through the first filter 41 into the second chamber 4. The first filter 41 can intercept particulate matter and other impurities. If maintenance of the first filter 41 or the interior of the second chamber is required, it can be opened through the first maintenance manhole 42 and the second maintenance manhole 43. The packing material in the second chamber is activated carbon, calcium oxide, and other purification materials, which can adsorb larger pollutant particles and moisture in the gas. The gas continues to rise and passes through the second filter 51 into the third chamber 5, where the second filter 51 further removes pollutants. Maintenance of the third chamber 5 is achieved through the third maintenance manhole 52. The packing material in the third chamber 5 is porous silica and other materials. Porous silica can adsorb more harmful gases. The gas continues to rise to the fourth chamber 6. The neutralizing solvent nozzle 62 in the fourth chamber 6 starts spraying neutralizing agent when the device is turned on, which reacts with the pollutants remaining in the gas to achieve the effect of chemical purification. The sprayed neutralizing solution will fall to the bottom of the shell and finally be discharged from the equipment through the tail liquid pipe 32. The fourth chamber 6 is maintained through the fourth maintenance manhole 61. The gas continues to rise and passes through the demister layer 7 to remove the entrained droplets and prevent liquid from being carried in the tail gas. The purified gas is discharged from the exhaust pipe 71. The second sensor group 8 includes, but is not limited to, a pressure sensor, a flow sensor, and a toxic gas sensor. The second sensor group 8 detects in real time whether the emitted gas meets the environmental protection standards.

[0021] This application employs a three-stage purification process combining physical interception, physical adsorption, and chemical neutralization. The process involves preliminary treatment in the first chamber, filtration and further reaction in the second and third chambers, neutralization in the fourth chamber, and liquid removal via a demisting layer. This ensures more thorough purification. Furthermore, each chamber is equipped with an inspection port for convenient maintenance and a longer service life. Combined with various sensors, real-time monitoring and precise control are achieved throughout the purification process. In summary, this equipment, through its staged treatment, convenient maintenance, and real-time monitoring design, achieves high efficiency, stability, and environmental friendliness in gas purification.

[0022] This invention provides a gas purification and neutralization device that can handle complex waste gases, produces more environmentally friendly purified gases, increases the versatility of the device, enables each layer of packing to participate more effectively in purification, extends the service life of the packing, achieves full-process monitoring during use, reduces the occurrence of failures, and lowers maintenance costs.
