[0023] Reference Figure 1-2 The utility model provides a novel deodorizing biological filter structure, comprising:

[0024] The pre-wash tank 101, the biofilter 102, the circulating water tank 111 and the humidifying water tank 112, the pre-wash tank 101 and the biofilter 102 are fixedly connected with a connecting air duct 103, the bottom of the biofilter 102 is provided with an air distribution component, the pre-wash tank 101 and the biofilter 102 are respectively filled with a pre-wash tank filler 106 and a biological filler 107, the pre-wash tank filler 106 is made of PP balls, which have the advantages of light weight and large specific surface area; the bottom of the biological filler 107 is made of large-grained volcanic rock, which can provide a space for microorganisms to attach and prevent the filler from entering the air distribution pipe, and the upper part is made of ceramsite + Bamboo charcoal mixed filler, an air inlet pipe 108 is fixedly connected to the pre-wash tank 101, an air outlet pipe 109 is fixedly connected to the biofilter 102, a demister 110 is provided on the air outlet pipe 109, a pre-wash spray equipment body 113 and a return pipe are respectively provided between the pre-wash tank 101 and the circulating water tank 111, a circulating water pump 114 is provided on the pre-wash spray equipment body 113, a humidifying spray equipment body 115 is provided between the humidifying water tank 112 and the biofilter 102, a humidifying water pump 116 is provided on the humidifying spray equipment body 115, and a fan 117 is provided on one side of the air inlet pipe 108.

[0025] Among them, the air distribution component includes an air distribution main pipe 104 and multiple air distribution branch pipes 105, and multiple support frames 121 are fixedly connected to the bottom of the biological filter 102. The air distribution main pipe 104 is fixedly connected in the biological filter 102, and the air distribution main pipe 104 is fixedly connected to the connecting air duct 103. The air distribution branch pipe 105 is fixedly connected to the air distribution main pipe 104, and the air distribution branch pipe 105 is fixedly connected to the support frame 121. A plurality of air outlets are evenly opened on the air distribution branch pipe 105. The odor is evenly transported to the biological filter 102 through the air distribution main pipe 104 and the air distribution branch pipe 105, and when necessary, it can also serve as an aeration system to provide oxygen for the growth of microorganisms on the filler, which can avoid the hardening of the filler in the filter tank and maintain a suitable and stable living environment for the microorganisms inside the filler.

[0026] Furthermore, the air outlet is located at a position forty-five degrees downwardly obliquely on the cross section of the air distribution branch pipe 105, and multiple air outlets are symmetrically distributed on the air distribution branch pipe 105. The diameter of the air outlet is smaller than the diameter of the filler, so that the gas can be evenly transported to the biofilter 102, and the filler can be prevented from falling into the pipe.

[0027] Furthermore, a spray head 118 is fixedly connected to the humidifying spray equipment body 115. The spray head 118 is fixedly inserted into the connecting air duct 103 and extends into the connecting air duct 103. A circular hole is provided at the bottom of the air distribution main pipe 104. The odor in the connecting air duct 103 can be humidified in advance through the setting of the spray head 118. The water vapor enters the biological filter tank 102 with the gas and humidifies the biological filler 107 from the bottom of the biological filler 107. At the same time, the setting of the circular hole avoids the accumulation of nutrient solution in the pipeline.

[0028] Furthermore, an inspection port 119 is provided on the pre-wash tank 101 and the biological filter tank 102. A cover plate is hinged on the top wall of the pre-wash tank 101 and the biological filter tank 102 at the inspection port 119. A sealing silicone pad 120 is provided on the cover plate. The silicone sealing ring has excellent sealing performance, is resistant to high and low temperatures, is corrosion-resistant, has stable chemical properties, is not easy to age, is non-toxic and harmless, and the inspection port 119 is also used for loading and unloading fillers.

[0029] Furthermore, the bottom of the pre-wash tank 101 and the biological filter tank 102 are fixedly connected with a drain pipe 122 , and a valve is provided on the drain pipe 122 , and the user can discharge the liquid in the pre-wash tank 101 and the biological filter tank 102 through the drain pipe 122 .

[0030] During use, the odor enters the pre-wash tank 101 through the air inlet pipe 108, and the pre-wash spray equipment body 113 in the pre-wash tank 101 continuously sprays water. After the water flows through the pre-wash tank filler 106, it flows into the circulating water tank 111 at the bottom of the pre-wash tank 101 through the return pipe, and then sprays the pre-wash tank 101 through the pre-wash spray equipment body 113. After passing through the pre-wash tank 101, the odor passes through the pre-wash tank filler 106, and after the impurities and water-soluble gases in the gas are washed away by spraying, it enters the biological filter 102 through the connecting air duct 103. The odor passes through the pre-wash tank 101 and the pre-wash tank filler 106. The odor passes through the main air distribution pipe 104 and the branch air distribution pipe 105, and flows evenly from the main air distribution pipe 104 to each branch air distribution pipe 105, and then flows out through the air outlet holes on both sides of the branch air distribution pipe 105. A large number of microorganisms are enriched on the biological filler 107. The humidification spray equipment body 115 and the spray head 118 operate intermittently to provide suitable temperature and humidity for the growth of microorganisms. When the odor passes through the biological filler 107, the pollutants such as hydrogen sulfide, ammonia, and non-methane total hydrocarbons in the odor are removed through the degradation action of microorganisms, and then discharged through the demister 110 on the top of the filter tank through the outlet pipe 109.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
