Description

A device for purifying odor after industrial wastewater treatment

Technical Field

The utility model relates to the technical field of wastewater odor purification, in particular to a device for purifying odor after industrial wastewater treatment.

Background Art

Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with the water. During the operation of industrial wastewater treatment plants, a large amount of unpleasant odors will be emitted, such as ammonia, hydrogen sulfide, etc. If the odor is directly discharged to the outside, it will have a serious impact on the atmosphere and the surrounding environment, so an odor purification device is needed to deodorize and purify the odor.

According to a highly efficient odor purification device after industrial wastewater treatment disclosed in Chinese patent announcement number CN217437982U, the patent sprays the odor by setting multiple groups of spray pipes, and at the same time, the odor after the spraying treatment can be adsorbed and deodorized under the cooperation between the first purification layer and the second purification layer, and an efficient and stable deodorization effect can be achieved. However, the patent still has certain shortcomings in the actual use process. Since the first purification layer and the second purification layer are both arranged on the inner side of the shell, and the shape of the second purification layer is very complicated, when the internal filler needs to be replaced after a period of use, a large amount of labor and time of the staff will be consumed, and the operation process is very cumbersome. The patent is provided with a flushing spray component for flushing the first purification layer and the second purification layer on the biological purification component. The first purification layer and the second purification layer for adsorption generally have a porous structure, which is difficult to be easily washed away by the sprayed water after adsorption. Usually, only a small part of the deodorization effect can be restored, which is relatively useless in actual application. In this regard, the present application provides an odor purification device after industrial wastewater treatment to solve the above problems.

It should be noted that the interior of the pretreatment box 1 is connected with the interior of the deodorization box 2, so that the odor can flow upward normally. The length and width of the inner side of the support frame 301 are respectively smaller than the length and width of the support mesh 303, so that the odor can only flow upward through the inner side of the support frame 301 and the support mesh 303. The first adsorption layer 304 is a honeycomb activated carbon filler layer, which can have excellent adsorption capacity. The second adsorption layer 305 is a composite filler layer, which can be a mixed filler mainly composed of inert materials that are difficult to biodegrade, such as polypropylene rings, polyurethane, ceramic particles and volcanic rocks, which can deodorize without providing nutrients to microorganisms.

In this embodiment, the spray assembly 500 is a structure for pre-treating odor by spraying.

As shown in Figures 1, 2 and 3, the spray assembly 500 includes an air inlet pipe 501 fixedly connected to the left side of the pretreatment box 1, a liquid inlet pipe 502 fixedly connected to the right side of the pretreatment box 1, a support block 503 fixedly connected to the right side of the pretreatment box 1, a boosting valve 504 fixedly connected to the bottom of the liquid inlet pipe 502 and fixedly connected to the top of the support block 503, the left end of the liquid inlet pipe 502 passes through the right side of the pretreatment box 1 and is fixedly connected to four extension pipes 505, the bottom of the extension pipe 505 is fixedly connected to evenly distributed spray heads 506, a fixing frame 507 is fixedly connected between the tops of the four extension pipes 505, a water inlet pipe 508 is fixedly connected to the right side of the pretreatment box 1, three air baffles 509 are fixedly connected to the inner side of the pretreatment box 1, a discharge pipe 510 is fixedly connected to the bottom of the pretreatment box 1, and an electric control valve 511 is fixedly installed on the outer side of the discharge pipe 510.

The top of the air baffle 509 is inclined, and the three air baffles 509 are staggered left and right, so that the odor can move smoothly upward along the channel formed by the three air baffles 509. The fixed frame 507 is located on the outside of the liquid inlet pipe 502, and the front and back of the fixed frame 507 are fixedly connected to the front and rear inner walls of the pretreatment box 1 respectively, so that the fixed frame 507 can play an auxiliary supporting role for the extension tube 505.

In addition, the discharge pipe 510 can be opened at a fixed time under the action of the electric control valve 511, and the water flow rate needs to be controlled during the opening process to keep the water flow rate at a slow state, so as to facilitate the control of the water level inside the pretreatment box 1 and prevent the odor from being directly carried away by the turbulent water flow. Among them, a water level sensor and other sensing equipment can be set on the inner side of the pretreatment box 1 to facilitate the judgment of the water level.

It can be understood that the odor treated inside the pretreatment box 1 can be effectively pretreated and purified, thereby reducing the adsorption burden of the first adsorption layer 304 and the second adsorption layer 305, and also increasing the usable time of the first adsorption layer 304 and the second adsorption layer 305, so that they can be used for a long time and efficiently.

The working principle of the above embodiment is:

When purifying the odor after industrial wastewater treatment, the treated water is injected into the interior of the pretreatment box 1 through the water inlet pipe 508, and the odor is input into the interior of the pretreatment box 1 through the air inlet pipe 501, and the booster valve 504 is started to allow the treated water to be transported to the interior of each extension pipe 505 through the liquid inlet pipe 502, and then sprayed out through the spray head 506. The odor inside the pretreatment box 1 slowly moves upward in the water under the action of the three air baffles 509. After the odor after water treatment floats to the surface of the water, it will be purified for the second time by the water mist sprayed by the spray head 506. The purified gas will continue to move upward to the interior of the deodorizing box 2, and the exhaust fan 402 is started to allow the gas inside the deodorizing box 2 to pass through the first and second air baffles 509 in sequence. After adsorption and filtration of the first adsorption layer 304 and the second adsorption layer 305, they are discharged through the exhaust box 401, which can effectively realize the purification of odor. After long-term use, the stuffing needs to be replaced. Loosen the bolts 310 and turn the cover 307 downward to take out the stuffing box 302 from the inside of the deodorizing box 2, and replace the stuffing of the first adsorption layer 304 and the second adsorption layer 305 inside. After the replacement is completed, they are placed on the top of the two support frames 301 respectively, and the cover 307 is turned upward to make it abut against the front of the two abutting blocks 306. Tighten the bolts 310, and the sealing performance of the connection can be improved under the action of the sealing ring 308, so that the odor purification work can continue.

Compared with the prior art, the odor purification device for industrial wastewater treatment, through the coordinated use of the spray assembly 500 inside the pretreatment box 1 and the deodorizing box 2 and the adsorption assembly 300 on the top, can efficiently treat the wastewater odor while facilitating the replacement of the adsorption filler. During the operation, the odor can be purified step by step, so that the odor can be efficiently purified and discharged to the outside. At the same time, it is also convenient to replace the adsorption filler to ensure the stability of the adsorption capacity, thereby greatly improving the practicality of the odor purification device for industrial wastewater treatment, and solving the problem that it is inconvenient to replace the adsorption filler in the existing odor purification device for industrial wastewater treatment.
