DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0032] Combination Figure 1 and Figure 3The utility model is a composite deodorizing device for a drainage pump station, comprising a box body 1, an air inlet pipe 2 is passed through and fixedly connected to the left side of the box body 1, an air inlet pretreatment section 3 is arranged on the left side of the inner wall of the box body 1, and a slide rail 22 is fixedly connected to the top and bottom of the air inlet pretreatment section 3, a first filter 8 is passed through and slidably connected between the top and bottom of the left slide rail 22, and a second filter 9 is passed through and slidably connected between the top and bottom of the right slide rail 22;

[0033] The malodorous gas collected by the drainage pump station enters the composite deodorization device through the air inlet pipe 2. The rear end of the air inlet pipe 2 is the air inlet pretreatment section 3, which is provided with a first filter 8 and a second filter 9. The first filter 8 is mainly used to remove large impurities in the air inlet of the device, reduce the load of the second filter 9, and extend the service life of the second filter 9. The second filter 9 is mainly used to remove fine particles carried in the air inlet and reduce the humidity of the gas, thereby increasing the service life of the ion generating device. The first filter 8 and the second filter 9 are installed in a plug-in manner, which is convenient for regular replacement;

[0034] A cleaning mechanism is fixedly connected to the rear side of the inner wall of the air inlet pretreatment section 3, and the cleaning mechanism includes a fixed frame 18, a screw rod 19 passes through the top of the fixed frame 18 and is rotatably connected, a cleaning brush 21 passes through the top of the outer ring of the screw rod 19 and is threadedly connected, a motor 20 is fixedly connected to the left side of the top of the box body 1, and the output end of the motor 20 is fixedly connected to the screw rod 19, and a collection box is slidably connected to the bottom of the fixed frame. The motor 20 drives the screw rod 19 to rotate, so that the cleaning brush 21 moves up and down to clean the dust on the surface of the filter. The cleaned dust falls into the collection box 24, and then the device is opened, the collection box 24 can be pulled out, and the dust inside is regularly cleaned.

[0035] Combination Figure 2 An ion generating section 4 is arranged on the right side of the air inlet pretreatment section 3, and a plurality of high-energy ion tubes 10 are arranged through the inner wall of the ion generating section 4, a first air inlet baffle 11 is arranged on the right side of the ion generating section 4, a first air inlet channel 12 is opened in the middle of the first air inlet baffle 11, an ion wind reaction section 5 is arranged on the right side of the first air inlet baffle 11, and a gas guide folding plate 13 is fixedly connected to the top and bottom of the inner wall of the ion wind reaction section 5;

[0036] The malodorous gas that has been pre-treated and filtered then enters the ion generating section 4, and several high-energy ion tubes 10 are arranged horizontally in this area. Under the action of the high-voltage electric field, the high-energy ion tubes 10 generate a large number of high-energy particles, which collide with oxygen molecules in the air to form positive and negative oxygen ions. The malodorous gas and the high-energy positive and negative oxygen ions generated by the ion generating section 4 enter the ion wind reaction section 5 through the first air inlet channel 12 on the first air inlet baffle 11. In this area, the two are densely mixed and collided. By setting the gas guide folding plate 13, the flow path length of the ion gas and the malodorous gas in the reaction section is extended, and the contact time of the mixing and collision of the two is enhanced, so as to maximize the use of the space of the ion wind reaction section 5 and enhance the reaction effect. The gas guide folding plate 13 is installed at an angle, and the horizontal inclination angle is preferably 70-75° to ensure a better gas flow state.

[0037] Combination Figure 2 An activated carbon adsorption section 6 is arranged on the right side of the inner wall of the box body 1, a carbon storage assembly 23 is fixedly connected in the middle of the activated carbon adsorption section 6, a plurality of carbon storage mounting tracks 17 are penetrated and fixedly connected on the front side of the carbon storage assembly 23, honeycomb block activated carbon 16 is arranged between the left and right sides of the carbon storage mounting track 17, a second air inlet baffle 14 is fixedly connected on the right side of the activated carbon adsorption section 6, a second air inlet channel 15 is opened on the right side of the second air inlet baffle 14, and an air outlet pipe 7 is penetrated and fixedly connected on the right side of the top of the box body 1;

[0038] The malodorous gas is oxidized, decomposed and removed in large quantities in the ion wind reaction section 5, and then enters the activated carbon adsorption section 6 through the second air inlet channel 15 on the second air inlet baffle 14. The adsorption filter material adopts honeycomb block activated carbon 16, which is loaded in the carbon storage component 23. Several carbon storage components 23 are loaded into the activated carbon adsorption section 6 of the composite deodorization device box 1 through the carbon storage installation track 17. The huge specific surface area and fine porous surface structure of the honeycomb block activated carbon 16 are used to adsorb and remove the odor molecules remaining after the ion wind reaction section 5 is deodorized, and the overall deodorization effect of the deodorization device is enhanced. After ensuring that the gas is stable and meets the standard, it is discharged from the outlet pipe 7 to the composite deodorization device for drainage pumping station. When the composite deodorization device for drainage pumping station is in operation, the honeycomb block activated carbon 16 in the carbon storage components 23 at different positions in the upper and lower parts will gradually tend to adsorption saturation. During this period, the upper and lower installation positions of different carbon storage components 23 can be replaced sequentially to give full play to the adsorption capacity of all honeycomb block activated carbon 16. According to the deodorization operation effect of the composite deodorization device, the honeycomb block activated carbon 16 is updated and replaced after it is fully adsorbed and saturated. The connection between the carbon storage installation track 17 and the carbon storage assembly 23 allows the replacement and installation of the honeycomb block activated carbon 16 to be realized quickly, with low labor intensity and saving manpower and material resources.

[0039] Working principle: When the utility model is in use, the malodorous gas collected by the drainage pump station enters the composite deodorization device through the air inlet pipe 2, and the large impurities in the air inlet of the device are removed through the first filter 8, reducing the load of the second filter 9, and then the motor 20 drives the screw 19 to rotate, so that the cleaning brush 21 moves up and down to clean the dust on the surface of the filter. By opening the device, the collection box 24 can be pulled out, and the dust inside can be cleaned regularly to extend the service life of the filter. The second filter 9 mainly removes fine particles carried in the air inlet and reduces the humidity of the gas, thereby increasing the service life of the ion generating device. The first filter 8 and the second filter 9 are installed in a plug-in manner, which is convenient for regular replacement. The malodorous gas after pretreatment and filtration then enters the ion generating section 4, and a large number of high-energy particles are generated under the action of the high-voltage electric field through the high-energy ion tube 10. The high-energy particles collide with oxygen molecules in the air to form positive and negative oxygen ions. The malodorous gas and the high-energy positive and negative oxygen ions generated by the ion generating section 4 enter the ion wind reaction section 5 through the first air inlet channel 12 on the first air inlet baffle 11. In this area, the two are densely mixed and collided. By setting the gas guide folding plate 13, the flow path length of the reaction section ion gas and the malodorous gas is extended, the contact time of the mixing and collision of the two is enhanced, and the space of the ion wind reaction section 5 is utilized to the maximum extent to enhance the reaction effect. Then, it enters the activated carbon adsorption section 6 through the second air inlet channel 15 on the second air inlet baffle 14. The huge specific surface area and fine porous surface structure of the honeycomb block activated carbon 16 are utilized to adsorb and remove the odor molecules remaining after deodorization in the ion wind reaction section 5, thereby enhancing the overall deodorization effect of the deodorization device and ensuring that the gas is discharged from the outlet pipe 7 to the drainage pump station after being stably up to standard.
