[0032] Example 1

[0033] This embodiment is a first embodiment of a biological deodorization device, such as... Figure 1 As shown, the device includes a biological deodorization box 100 and a drain plate. The drain plate is located inside the biological deodorization box 100. The biological deodorization box 100 is a box-shaped structure with an open top. The drain plate divides the inside of the biological deodorization box 100 into a deodorization layer 110 and a water accumulation layer 120. Biological packing material 200 is piled up inside the deodorization layer 110. The biological deodorization box 100 has an air inlet 121, an air outlet 111, and a liquid outlet 122. The air inlet 121 and the liquid outlet 122 are both connected to the water accumulation layer 120, and the air outlet 111 is connected to the deodorization layer 110.

[0034] It also includes a fan 800, which is connected to the air outlet 111. By installing the fan 800 at the air outlet 111, the speed at which the gas flows to the air outlet 111 is accelerated, thereby increasing the deodorization efficiency.

[0035] After the spray nozzle 600 sprays onto the biological packing material 200, excess liquid flows into the bottom of the biological deodorization box 100. The liquid outlet 130 is located below the biological packing material 200 and is connected to the spray nozzle 600. By setting the liquid outlet 130, the water can be recycled back to the spray nozzle 600, thus saving water resources.

[0036] The residual chlorine removal device 700 is in communication with the spray head 600. The water sprayed by the spray head 600 is usually the treated reclaimed water in the plant area, and the reclaimed water usually contains a certain amount of residual chlorine. Since chlorine has a killing effect on the microorganisms in the biological filler 200, which is not conducive to the growth of microorganisms, the residual chlorine removal device 700 is arranged to remove the chlorine in the water sprayed into the biological deodorization tank 100 by the spray head 600, reduce the impurities sprayed into the biological filler, and be conducive to the growth and reproduction of microorganisms in the biological filler 200.

[0037] The top plate 300, the cover plate 400, the sliding assembly 500, and the spray head 600 are further included. The top plate 300 is sealingly connected to the biological deodorization tank 100, is located at the upper end opening of the biological deodorization tank 100, and seals the opening of the biological deodorization tank 100. The top plate 300 is preferably integrally formed with the biological deodorization tank 100, and an inspection opening 310 is formed in the top plate 300. The cover plate 400 is sealingly connected to the top plate 300 through the sliding assembly 500, is located at the inspection opening 310, and the spray head 600 is arranged on the cover plate 400. The inspection opening 310 and the cover plate 400 can be correspondingly arranged in multiple numbers, and the spray head 600 is arranged on each of the multiple cover plates 400.

[0038] The stirring mechanism 900 is further included. The stirring mechanism 900 is arranged on the top plate 300 and is preferably located between adjacent two cover plates 400. The stirring mechanism 900 uses an existing stirring device on the market. The stirring mechanism 900 includes a rotating motor, a stirring shaft, and stirring blades. The rotating motor is arranged on the top plate 300 and drives the stirring shaft to rotate. The stirring blades are arranged on the stirring shaft and are located in the biological filler 200. The stirring mechanism 900 is arranged to stir the biological filler 200, so that the microorganisms in the biological filler 200 can fully contact with the waste gas, thereby improving the gas treatment effect.

[0039] At the same time, since the spray head 600 is installed above the biological filler 200, it is difficult to uniformly wet all the microorganisms in the biological filler 200. Simultaneously, fixing the spray head 600 in one position can easily cause the biological filler 200 to be cemented together, which greatly reduces the biological treatment efficiency. Therefore, the stirring mechanism 900 can also mix the water sprayed by the spray head 600 in the biological filler 200 uniformly, thereby improving the gas treatment effect.

[0040] The working principle of the biological deodorization device of the embodiment is as follows:

[0041] When biological deodorization is performed, the biological filler 200 is stacked on the leakage plate, and the biological filler 200 is located in the deodorization layer 110. The odor is discharged into the biological deodorization tank 100 through the air inlet 121, and the biological filler 200 in the biological deodorization tank 100 performs biological deodorization on the odor. At the same time of deodorization, the liquid is sprayed on the biological filler 200 through the nozzle 600 after the residual chlorine is removed by the residual chlorine removal device 700, and the biological filler 200 is stirred by starting the stirring mechanism 900. The purified gas is discharged from the biological deodorization tank 100 through the air outlet 111. The excess water from the nozzle 600 flows to the bottom of the biological deodorization tank 100, and then flows to the nozzle 600 again after the residual chlorine is removed by the residual chlorine removal device 700 through the liquid outlet 130 for recycling. After long-term use, the nozzle 600 is moved out of the biological deodorization tank 100 by sliding the cover plate 400 through the sliding assembly 500, so that the nozzle can be repaired or replaced, thereby reducing impurities sprayed into the biological filler 200.

When the access opening 310 is located around the top plate 300, the cover plate 400 is slid on the side of the top plate 300 through the roller 520, so that the cover plate 400 connected to the nozzle 600 to be repaired can be slid to the outside of the biological deodorization tank 100, thereby facilitating the repair or replacement of the nozzle 600.
