Technical Field

[0001] The utility model relates to the technical field of biological deodorization, in particular to an RTO biological deodorization treatment device. Background Art

[0002] In the process of some production and processing, it is inevitable that some gases with foul odors will be produced. These odors will not only affect the ecological environment, but also cause great harm to human health, damage people's olfactory nerves, and cause people's physical and mental discomfort. Therefore, it is necessary to deal with the odor gas pollution. Biological deodorization mainly uses microorganisms for deodorization. The odorous substances are converted through the metabolism of microorganisms. When the existing microbial equipment is deodorizing, most of them introduce the odorous gas into the treatment box through a fan or air pump. However, these discharged gases will be mixed with certain impurities. After a long period of use, the impurities will accumulate in the biological filler, thereby affecting the deodorization effect. Utility Model Content

[0005] Preferably, the sliding engagement mechanism includes: a dust and impurity filter box, which is slidably mounted on the side surface of the absorption and diffusion barrel, and the outer surface of the absorption and diffusion barrel is fitted with the outer surface of the dust and impurity filter box, and the side surface of the absorption and diffusion barrel is fixedly mounted with a slide groove, and the slide groove is L-shaped, and the outer surface of the slide groove is slidably mounted with a snap plate, and the outer surface of the snap plate is fitted with the outer surface of the dust and impurity filter box, and the side mark surface of the dust and impurity filter box is fitted with the outer surface of the snap plate.

[0006] By adopting the above technical solution, the gas drawn in by the exhaust fan can be filtered through the dust and impurities filter box, and the dust and impurities in the gas can be retained, so that the dust and impurities in the gas are not easily entered into the biological filler through the water flow to cause accumulation and affect the metabolism of microorganisms. At the same time, the dust and impurities filter box can be fixed in the absorption and diffusion barrel through the snap plate and the slide groove, so that the dust and impurities filter box can be taken out for cleaning.

[0008] By adopting the above technical solution, the gas drawn into the absorption and diffusion barrel enters the interior of the connecting air pipe through the filtration of the dust and impurities filter box, and is dispersed through the gas distribution holes evenly arranged on the outer surface of the connecting air pipe, so that the gas can be dispersed and discharged, and contact with the solution in the absorption and diffusion barrel over a large area, thereby increasing the speed at which the solution absorbs odorous substances in the gas.

[0009] Preferably, an air inlet valve is fixedly installed on the outer surface of the pipette, and the air inlet valve is connected to the air pump, the bottom of the treatment and purification barrel is inclined, and a drain pipe is fixedly opened on the outer surface of the treatment and purification barrel, and the drain pipe is located at the lowest point of the treatment and purification barrel, and the interior of the treatment and purification barrel is provided with partitions, and the partitions of the treatment and purification barrel are filled with different types of biological metabolic fillers.

[0010] By adopting the above technical scheme, the solution that absorbs odorous substances can be discharged from the absorption and diffusion barrel into the treatment and purification barrel through a water pump, so that the liquid passes through the biological metabolic filler, and the odorous substances in the liquid are metabolized by the microorganisms in the biological metabolic filler. By adjusting the opening and closing of the air intake valve, the amount of air entering the biological metabolic filler is controlled, and the metabolic rate of the biological metabolic filler is increased by the air.

Through the operation of the water pump, the liquid is discharged outward through the drain pipe, and the solution in the drain pipe is atomized through the atomizing nozzle, and the discharged gas is sprayed again to merge and take away the residual odor substances in the discharged gas, thereby improving the absorption treatment rate.

[0013] Preferably, a shielding structure is provided inside the absorption diffusion barrel, and the shielding structure prolongs the residence time of the remaining gas after absorption in the absorption diffusion barrel, so that the residual gas in the gas can be absorbed again by the atomized liquid sprayed from the atomizing nozzle.

[0014] By adopting the above technical solution, the time for gas to pass through the absorption diffusion barrel can be extended by tilting the baffle, so that the time for gas to be discharged from the exhaust port is delayed, so that the liquid atomized and sprayed from the atomizing nozzle can contact the gas more fully, thereby enhancing the removal of odorous substances in the gas.

[0015] Preferably, the shielding structure includes: an inclined baffle, which is fixedly installed inside the absorption and diffusion barrel, and the end of the inclined baffle close to the water pump is hollow, the hollow inclined baffle is connected to the drain pipe, and the outer surface of the inclined baffle is evenly provided with atomizing nozzles, and the absorption and diffusion barrel is provided with an exhaust port at one end away from the gas distribution hole.

It will be metabolized by microorganisms again, so that the liquid can be recycled and reused.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the RTO biological deodorization treatment device:

[0018] 1. When the exhaust fan is working, the odor will be discharged into the absorption and diffusion barrel through the air inlet pipe, so that the gas must be filtered by the dust and impurities filter box before entering the liquid in the absorption and diffusion barrel. The snap plate slides on the side surface of the slide groove, and the snap plate and the dust and impurities filter box are engaged, so that the dust and impurities filter box can be fixed and removed in the absorption and diffusion barrel, which is convenient for cleaning and replacing the dust and impurities filter box. At the same time, it can reduce the accumulation of dust and impurities in the biological metabolic filler through the circulation of the liquid, causing the influence of slow metabolism;

[0019] 2. The filtered gas will be discharged from the connecting air pipe and dispersed into the liquid in the absorption and diffusion barrel through the gas distribution holes, so that the liquid and the discharged gas will contact with a large area, increasing the amount of odor substances in the gas absorbed by the liquid. At the same time, a small amount of air will be discharged through the water pump and the air inlet valve, so that the liquid will enter the treatment and purification barrel, and through the biological metabolism filler, the microorganisms in the biological metabolism filler will metabolize the odor substances in the water. At the same time, the discharged air will accelerate the metabolism of odor substances by microorganisms, thereby improving the efficiency of reaction metabolism;

[0020] 3. After the gas is discharged through the gas distribution holes, it will continue to float upward and be blocked by the inclined baffle to extend the time for the gas to pass through the absorption and diffusion barrel, so that the water metabolized by the biological metabolic filler will be atomized and sprayed out from the atomizing nozzle again, and the passing gas will be fused again, and the residual odor substances in the gas will be fused and taken away. The time is extended by the obstruction of the inclined baffle so that the gas can fully contact with the atomized solution. The water after absorbing the odor substances will flow back to the bottom of the absorption and diffusion barrel along the inclined baffle and re-enter the treatment and purification barrel for circulation treatment, so that the gas stays in the absorption and diffusion barrel for a longer time so that it can be completely fused with the solution in the absorption and diffusion barrel, thereby improving the gas treatment quality.
