Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment biological filter with a sliding nozzle. Background Art

[0002] The waste gas treatment biofilter is a purification device that uses the metabolism of microorganisms to decompose harmful components in waste gas into harmless substances such as carbon dioxide and water before discharging them. During the decomposition process, microorganisms need to attach to organic fillers and be provided with nutrients by organic fillers.

[0003] Biofilter is a biological treatment technology that uses the natural decomposition ability of microorganisms (mainly bacteria and fungi) to purify organic pollutants in sewage or waste gas. This process simulates the self-purification of soil and water in nature. By constructing an artificial ecosystem, microorganisms are attached to the surface of filter materials (such as crushed stone, gravel, volcanic rock or special plastic media) to form a biofilm. When the fluid (water or air) containing pollutants passes through this biofilm, the organic matter in it is absorbed by the microorganisms and converted into harmless carbon dioxide, water and the microorganisms' own biomass, thereby achieving the purpose of purification.

[0004] The existing filter tank equipment has one section as a pretreatment section and the other section as a reaction section. During the pretreatment, the purification material needs to be pre-filled inside so that dust and other debris in the exhaust gas can be removed when the exhaust gas enters the pretreatment section. However, after a long period of treatment, the purification material cannot effectively treat the exhaust gas. When the untreated exhaust gas enters the reaction section, it will affect the growth and reproduction of microorganisms in the reaction section. The spraying equipment in the reaction section needs to be started and stopped for a long time. Long-term use will not only consume a lot of electricity, but also easily cause damage to electrical components. Since the spraying surface of the nozzle is a circular surface, the fixed nozzle cannot cover and spray the microorganisms in the pool. This uneven spraying phenomenon is not conducive to maintaining appropriate humidity for the biological filler, affecting the growth and reproduction of microorganisms, and further causing a decrease in the efficiency of microorganisms in decomposing harmful components in the exhaust gas. Utility Model Content

[0005] In view of this, the utility model provides a waste gas treatment biological filter with a sliding nozzle, which replaces the pretreatment material in the cleaning tank through the replacement component in the cleaning tank, and replaces the filter material in a quick way to ensure the filtering effect of the waste gas, effectively prevent the influence of untreated waste gas on subsequent microorganisms, and slide the nozzle in the reaction tank through the sliding component, so that the nozzle can slide in the reaction tank to control the sliding platform through the slide rail and the servo motor, so that the position of the nozzle can be adjusted, and the microorganisms in the reaction tank are fully sprayed, the growth of microorganisms is promoted, and the effective degradation of the waste gas is ensured.
