[0002] Industrial waste refers to solid waste discharged during the production process of machinery, light industry and other industries. When it is incinerated or harmlessly treated, it will produce a lot of exhaust gas. The odor in the exhaust gas has a great impact on the environment. It is necessary to eliminate the odor before subsequent exhaust gas treatment or discharge.

[0003] The existing technology uses activated carbon or adsorption to purify and remove odor from tail gas. The particles in the tail gas are easy to clog the filter structure, resulting in poor odor removal effect, and filtration alone cannot completely remove the odor. Therefore, we propose an odor-eliminating emission device for industrial waste treatment. Utility Model Content

DETAILED DESCRIPTION

[0024] See also Figure 1-2 The utility model provides a technical solution: an odor-eliminating emission device for industrial waste treatment, comprising a deodorizing box 1 and an air port 2, wherein two air ports 2 are provided and connected to the middle positions on both sides of the deodorizing box 1, and the exhaust gas can enter the interior of the deodorizing box 1 from the air port 2 on the left side, and can be discharged to the outside from the air port 2 on the right side.

[0025] Two upper baffles 3 and two lower baffles 31 are fixed at the upper and lower left sides of the interior of the deodorizing box 1, respectively. The two upper baffles 3 are placed between the two lower baffles 31, and the upper baffles 3 and the lower baffles 31 are staggered. Three water spray pipes 14 are longitudinally fixed inside the deodorizing box 1 between the two upper baffles 3. A plurality of water spray heads 141 are evenly arranged at the bottom of each water spray pipe 14. A water inlet pipe 16 is connected to the front end of the deodorizing box 1 at the water spray pipe 14. The water inlet pipe 16 is communicated with the water spray pipe 14, so that the clean water pipeline is connected to the water inlet pipe 16. Then, clean water can be injected into the water spray pipe 14, and then sprayed downward in the form of water mist from the water spray head 141 between the two upper baffles 3, so as to remove impurities and odor particles from the exhaust gas entering the deodorizing box 1.

[0026] A water outlet pipe 15 communicating with the interior of the deodorizing box 1 is vertically connected to the bottom of the deodorizing box 1 between the two lower baffles 31. A valve 151 is installed on the water outlet pipe 15. The valve 151 is opened to an appropriate degree to allow water mist to accumulate between the two lower baffles 31, and the water can be discharged downward from the water outlet pipe 15, keeping the drainage speed consistent with the accumulation speed of the water mist, thereby preventing the water from overflowing due to an increase in the height of the accumulated water.

[0027] A frame 4 is vertically fixed to the right side of the interior of the deodorizing box 1, and cotton boards 41 are vertically fixed on both sides of the interior of the frame 4. A spray pipe 42 is longitudinally fixed to the interior of the frame 4 between the cotton boards 41, and a plurality of spray holes 421 connected to the interior of the spray pipe 42 are arranged below both sides of the spray pipe 42. A liquid outlet 13 connected to the interior of the deodorizing box 1 is arranged at the rear end of the deodorizing box 1 at the bottom of the side of the frame 4, and a filter screen 131 is embedded and installed inside the liquid outlet 13. The filter screen 131 is blocked inside the liquid outlet 13, and a fragrance solvent can be added to the interior of the right side of the deodorizing box 1. A water pump is installed at the rear end of the deodorizing box 1 and its inlet is connected to the liquid outlet 13, and the water pump outlet is connected to the spray pipe 42. After being filtered by the filter screen 131, the fragrance solvent is drawn by the water pump and enters the spray pipe 42, and then is sprayed from the spray hole 421 to wet the cotton board 41, so that the exhaust gas passing through can be further filtered of odor particles, and the exhaust gas containing fragrance is discharged from the air outlet 2 on the right.

[0028] The front end of the deodorizing box 1 on the side of the liquid spray pipe 42 is connected to a liquid inlet pipe 11, and the liquid inlet pipe 11 is communicated with the interior of the deodorizing box 1. A solenoid valve 111 is installed on the liquid inlet pipe 11, and the solenoid valve 111 is communicated with the interior of the liquid inlet pipe 11. When the fragrance solvent is lacking inside the right side of the deodorizing box 1, the solenoid valve 111 can be opened to replenish the deodorizing box 1. A liquid level sensor 12 is installed inside the deodorizing box 1 on the side of the frame 4. The height of the liquid level sensor 12 is less than the height of the air port 2. The liquid level height of the fragrance solvent can be detected by the liquid level sensor 12, and the solenoid valve 111 is opened to replenish the fragrance solvent when needed.

[0029] When in use, the exhaust pipe and the exhaust pipe of the tail gas are respectively connected to the air port 2 on the left and right through joints, the water inlet pipe 16 is connected to the clean water pipeline, and the liquid inlet pipe 11 is connected to the fragrance solvent, so that a water pump is provided at the rear end of the deodorizing box 1 at the liquid outlet 13, and its water inlet is connected to the liquid outlet 13, and the water outlet of the water pump is connected to the liquid spray pipe 42 through a pipeline, and the solenoid valve 111 and the liquid level sensor 12 are connected to the control computer, so that clean water enters the water spray pipe 14 and is sprayed downward from the water spray head 141 in the form of water mist. When the tail gas enters from the air port 2 on the left, after passing between the upper baffle plate 3 and the lower baffle plate 31, the sprayed water mist removes dust and odor particles between the two upper baffle plates 3, and then flows to the right side, keeping the valve 151 on the water outlet pipe 15 open to a certain extent can just accumulate the sprayed water mist together. The water is discharged from the water outlet pipe 15. When the liquid level sensor 12 detects that the fragrance solvent liquid level on the right side of the deodorizing box 1 is insufficient, the solenoid valve 111 is opened and the fragrance solvent is added to the right side of the deodorizing box 1 through the liquid inlet pipe 11 until it reaches the height of the liquid level sensor 12. The water pump installed at the rear end is started to extract the fragrance solvent from the liquid outlet 13. During the extraction, the filter screen 131 can be used to filter the impurities in the fragrance solvent. Then the fragrance solvent enters the spray pipe 42 and is sprayed from the spray holes 421 on both sides below and wets the surface of the cotton board 41. After that, the exhaust gas flows to the right and passes through the two cotton boards 41 in turn. The residual odor particles can be filtered out, and the cotton board 41 moistened with the fragrance solvent can be used to make the exhaust gas contain a certain fragrance, which has a better deodorizing effect. Finally, the exhaust gas is discharged from the air port 2 on the right.
