Technical Field

[0001] The present application relates to the field of chemical environmental protection technology, and in particular to a highly anti-corrosion and deodorization treatment device for a petrochemical wastewater pool. Background Art

[0002] At present, the diversity of products in the chemical industry determines that its production workshops have multiple processes. Each workshop and process device needs to be equipped with a wastewater pool, a grease trap, and a rainwater pool mixed with production wastewater, etc. There are many of them in the workshops and factory areas, some of which are as many as dozens. They do not occupy a large area but have a serious stench. They are usually temporarily closed with a cover. The toxic gases in the pool endanger the lives of the staff and cannot be discharged directly. The working environment of the factory workers is poor, and the factory's waste gas emissions do not meet the standards. The wastewater pools are scattered and numerous, which seriously affects the air in the factory area and surrounding areas, and the environmental pollution is worrying.

[0003] In the related art, in order to reduce the impact of exhaust gas emissions on the surrounding environment, factories generally choose to pass the exhaust gas into an adsorption device, and adsorb the exhaust gas through the filler in the adsorption device.

[0004] However, the exhaust gas contains water vapor. If the adsorption device is used directly to adsorb the gas, the filler in the adsorption device will absorb the water vapor together, thereby reducing the adsorption efficiency of the adsorption device for pollutants in the exhaust gas. The filler needs to be replaced frequently, which increases the workload of production personnel.

[0005] Therefore, how to reduce the water vapor in the exhaust gas and improve the adsorption efficiency of the adsorption filler has become an urgent problem to be solved in the exhaust gas emission process. Utility Model Content

[0030] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] Example 1.

[0033] Reference Figure 1 A high corrosion resistance and deodorization treatment equipment for a petrochemical wastewater pool includes a housing 1, an air inlet 11 and an air outlet 12 are formed on the housing 1, and further, a water removal component 2 and a filter component 3 are provided on the housing 1. Gas enters from the air inlet 11 of the housing 1, and after being filtered by the water removal component 2 and the filter component 3 in turn, the gas is discharged from the air outlet 12 of the housing 1.

[0034] A dewatering chamber 13 is formed on one side of the box body 1 . An air inlet 11 of the box body 1 is located on a side of the box body 1 close to the water outlet chamber. Gas enters the dewatering chamber 13 through the air inlet 11 .

[0035] Reference Figure 2 The dewatering assembly 2 includes a dewatering net 21, which is made of a metal material, preferably, aluminum. After the gas with water vapor passes through the dewatering net 21, the water vapor in the gas will condense on the dewatering net 21.

[0036] In order to improve the efficiency of the dehydration net 21 in removing water vapor in the gas, several dehydration nets 21 are arranged at intervals in the dehydration chamber 13. When in use, the gas passes through several dehydration nets 21, so that most of the water vapor carried in the gas can condense on the dehydration nets 21.

[0037] Furthermore, in order to allow the condensed water on the dewatering net 21 to drip quickly, the dewatering net 21 is arranged at an angle in the dewatering chamber 13, and preferably, the angle of inclination of the dewatering net 21 is 45 degrees. When the water vapor in the gas condenses on the dewatering net 21, the condensed water will drip along the inclination direction of the dewatering net 21. By allowing the condensed water on the dewatering net 21 to drip quickly, the dewatering net 21 can continuously collect the water vapor in the gas.

[0038] A first row of condensation pipes 14 is provided on the housing 1, and one end of the first row of condensation pipes 14 is connected to the bottom of the housing 1 near the water removal chamber 13. During daily use, the first row of condensation pipes 14 is in a closed state. After a period of use, in order to prevent the condensed water accumulated in the water removal chamber 13 from affecting the use of the housing 1, the first row of condensation pipes 14 is opened. At this time, the condensed water in the water removal chamber 13 is discharged from the first row of condensation pipes 14.

[0039] A first partition 15 and a second partition 16 are arranged in the box body 1, and the first partition 15 and the second partition 16 are arranged in parallel and spaced apart. A first air cavity 151 and a second air cavity 152 are formed on the side of the first partition 15 close to the box body 1, and an air distribution plate 153 is arranged between the first air cavity 151 and the second air cavity 152, and the air distribution plate 153 separates the first air cavity 151 and the second air cavity 152. An air passage 161 is formed between the side of the second partition 16 away from the first partition 15 and the box body 1. The filter assembly 3 includes a first filter cartridge 31 and a second filter cartridge 32, and a plurality of first filter cartridges 31 and a plurality of second filter cartridges 32 are arranged at intervals, and one end of the plurality of first filter cartridges 31 is connected to the first air cavity 151, and the other end is connected to the air passage 161. One end of the second filter cartridge 32 is connected to the second air cavity 152, and the other end is connected to the air passage 161.

[0040] When in use, the gas enters the first air cavity 151 from the dewatering cavity 13, and then passes through the first filter cartridge 31, the air passage 161, the second filter cartridge 32 and the second air cavity 152 in sequence, and finally is discharged from the air outlet. By increasing the flow path of the gas in the box body 1, the adsorption efficiency of the first filter cartridge 31 and the second filter cartridge 32 on the pollutants in the gas is improved.

[0041] Furthermore, since the gas passing through the first filter cartridge 31 and the second filter cartridge 32 is the gas generated by the petrochemical wastewater pool, the gas will corrode the first filter cartridge 31 and the second filter cartridge 32 in the process of passing through the first filter cartridge 31 and the second filter cartridge 32. Therefore, the inner sides of the first filter cartridge 31 and the second filter cartridge 32 are wrapped with an anti-corrosion layer 33. When the corrosive gas passes through the first filter cartridge 31 and the second filter cartridge 32, the anti-corrosion layer 33 protects the first filter cartridge 31 and the second filter cartridge 32, thereby reducing the corrosion of the first filter cartridge 31 and the second filter cartridge 32 by the gas during use, thereby increasing the service life of the first filter cartridge 31 and the second filter cartridge 32.

[0042] During the production process, the gas has a certain amount of heat. When the gas passes through the first filter cartridge 31 and the second filter cartridge 32, condensed water will be generated on the surface of the first filter cartridge 31 and the second filter cartridge 32. If the condensed water accumulates between the first filter cartridge 31 and the second filter cartridge 32 for a long time, it will affect the use of the first filter cartridge 31 and the second filter cartridge 32. Therefore, a second row of condensation tubes 17 is provided on the first partition plate 15, and the second row of condensation tubes 17 extends toward the first air cavity 151. In addition, a third row of condensation tubes 18 is also provided on the box body 1, and the third row of condensation tubes 18 is connected to the first air cavity 151.

[0043] During the process of filtering the gas, the second row of condensation pipes 17 and the third row of condensation pipes 18 are in a closed state. When the box body 1 needs to be maintained, the second row of condensation pipes 17 and the third row of condensation pipes 18 are opened, so that the condensed water in the box body 1 can be discharged from the box body 1.

[0044] Example 2

[0045] Reference Figure 3 A highly corrosion-resistant and deodorizing treatment equipment for petrochemical wastewater pools includes dewatering cotton 22, which is installed on the top of the dewatering net 21. Furthermore, a vent pipe 19 is provided in the housing 1, one end of the vent pipe 19 is connected to the side of the dewatering chamber 13 close to the dewatering cotton 22, and the other end is connected to the first water storage chamber. After the gas passes through the dewatering net 21 and the dewatering cotton 22, it enters the first air cavity 151 through the vent pipe 19. After the gas is dewatered by the dewatering net 21, it passes through the dewatering cotton 22. When the housing 1 needs to be maintained, only the dewatering cotton 22 needs to be replaced. On the one hand, the dewatering effect of the gas is greatly improved, and on the other hand, the convenience of maintenance of the housing 1 can be improved.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
