Description

A biological deodorization tower

technical field

The utility model belongs to the technical field of deodorization towers, in particular to a biological deodorization tower.

Background technique

The domestic waste disposal method is not perfect, and the sanitary landfill method is generally used for stacking. The composition of domestic waste is relatively complex, and it is easy to rot and deteriorate during the stacking process, which in turn produces stench containing sulfur, nitrogen, hydrocarbons and their compounds. During the treatment process, the diffusion of malodorous gas will cause serious pollution to the atmosphere and the surrounding environment.

The stale garbage has complex components, and the composition of the odorous gas is complex. In the process of workshop treatment, the diffusion of the odorous gas can easily cause secondary pollution of the air and the surrounding environment. At present, there are mainly physical methods, chemical methods, and biological methods in the treatment of odorous gases. Both the physical method and the chemical method have problems such as serious secondary pollution, high operating costs, high energy consumption, complicated process, and a large number of equipment; biological deodorization method is currently widely used in China, which uses microorganisms to decompose organic substances such as odor in the exhaust gas, It has the advantages of good treatment effect, simple equipment required, and low energy consumption. However, due to the contact between gas and microorganisms, the excessive growth of microorganisms in the biological method will block the filter material, and it cannot be found and cleaned in time, resulting in low odor treatment effect.

Utility model content

The purpose of the utility model is to provide a biological deodorization tower to solve the problem of poor odor treatment effect and incomplete purification of stale garbage in the prior art.

The technical solution adopted in the utility model is: a biological deodorization tower, including a tower body, the lower end of the tower body is provided with an air inlet, the top of the tower body is provided with an exhaust port, and the tower body is sequentially An activated carbon layer, a water collection system, an atomized spray system, a biological filter layer, and a liquid storage tank are provided. The pool is connected with a high-pressure pump, and the high-pressure pump communicates with the atomizing spray system through a pipeline.

Further, the biological filter layer includes a first-stage biological filter layer and a second-stage biological filter layer.

Further, the film-hanging filler layer is microbial filler.

Further, a high-pressure blower is provided at the air inlet end.

The beneficial effects of the utility model are as follows: the odor is contacted and absorbed by the spray liquid, treated by multi-stage biological adsorption, and the adsorption and metabolism of microorganisms are fully utilized to achieve a good odor treatment effect, and has the advantages of high purification rate and small floor space. .

detailed description

In order to make the purpose, technical solutions and advantages of the present utility model clearer, various implementation modes of the present utility model will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that in each implementation manner of the present utility model, many technical details are proposed in order to enable readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.

As shown in Figure 1, a kind of biological deodorization tower comprises tower body 1, and the lower end of described tower body 1 is provided with air inlet 8, and air inlet 8 ends are provided with high-pressure fan 10, and the top of tower body 1 is provided with Exhaust port 9, activated carbon layer 2, water collection system 3, atomization spray system 4, biological filter layer, liquid storage tank 7 are arranged in the tower body 1 in sequence, and the biological filter layer is a multi-stage biological filter layer and in the filter layer A film-hanging packing layer 13 is provided inside, and the film-hanging packing layer 13 is microbial packing. The liquid storage tank 7 is connected with a high-pressure pump 11, and the high-pressure pump 11 communicates with the atomizing spray system 4 through a pipeline 12. The biological filter layer includes the first stage The biological filter layer 5 and the second-stage biological filter layer 6, the odor is treated by the first-stage biological filter layer 5 and the second-stage biological filter layer, which can thoroughly and effectively remove dust and malodorous substances in the gas.

When in use, the odor generated during the processing of stale garbage in the treatment workshop, the waste gas with a high dust content is firstly dedusted by the bag filter, and then enters the biological deodorization tower to remove the odorous substances; for the waste gas with a small dust content, it is directly Enter the biological deodorization tower to remove odorous substances. The deodorization tower is a cylindrical tower with swirl trays inside the tower. When working, the exhaust gas first enters the bottom of the tower, and forms a water curtain in contact with the bottom liquid, so that the dust in the exhaust gas dissolves in the water, and at the same time uses the medicament in the solution to neutralize and absorb the exhaust gas. The treated exhaust gas continues to rotate and rise under the guidance of the tray blades, and the liquid that flows down one by one is sprayed into droplets on the tray, so that there is a large contact area between the gas and the liquid; the droplets are driven by the airflow to rotate, The generated centrifugal force strengthens the contact between gas and liquid, and finally throws it to the tower wall and flows down the wall, passes through the overflow device to the next tray plate, and is atomized by the upward air flow again for gas-liquid contact.

The updraft enters the first-stage biological filter layer after continuous contact with the liquid flowing downward, and contacts with the film-hanging packing in the filter layer, and uses the microbial bacteria on the packing to eliminate the odor in the exhaust gas. The microorganisms that degrade the odor are mainly Ferrothiobacillus and Ferrobacteria ferrooxidans; the gas after contact and absorption continues to flow upward to the second-stage biological filter layer, the first-stage biological filter layer is the same as the second-stage biological filter layer, and the odorous substances are also removed by biosorption filtration; because The tower provides good gas-liquid contact conditions, the removal effect of H ₂ S and NH ₃ in the gas is very good, and the deodorization efficiency of the biological deodorization tower can reach more than 95%.

The utility model is not limited to the above-mentioned best implementation mode, anyone can draw other various forms of products under the enlightenment of the utility model, but no matter make any changes in its shape or structure, all have the same features as the application Or similar technical schemes all fall within the protection scope of the present utility model.
