Deodorization device for tail gas of garbage aerobic fermentation equipment

Abstract

The invention discloses a deodorization device for tail gas of garbage aerobic fermentation equipment. The deodorization device mainly comprises an inertial dust remover, an exhaust fan, a tubular heat exchanger and a U-shaped spraying deodorization device, wherein a plurality of dust-removal baffles are arranged in the inertial dust remover, tail gas produced during the fermentation of garbage enters the inertial dust remover through a pumping action of the exhaust fan, and fiber dust in the tail gas is separated from gas through inertial impaction of the dust-removal baffles; gas enters the tubular heat exchanger to be subjected to heat exchange; and finally, gas enters the U-shaped spraying deodorization device, and the foul smell is eliminated. Aiming at the properties that tail gas produced by virtue of rapid garbage composting and fermenting equipment contains a certain amount of fibrous dust, foul smell molecules, waste heat and the like, the tail gas is subjected to efficient stage treatment through combination of a smart structural design and physical-chemical treatment processes, so that the treatment efficiency of the equipment can be furthest improved, the loss of a chemical deodorization medicament is reduced, and the energy consumption is reduced.

Description

technical field [0001] The present invention relates to a deodorizing device, in particular to a deodorizing device for the tail gas of garbage aerobic fermentation equipment. -The rapid treatment equipment based on chemical principles belongs to the technical field of waste gas harmless treatment. Background technique [0002] Kitchen waste and agricultural organic waste, including straw and livestock and poultry manure, usually contain a high content of organic matter, but if they are directly used as fertilizer without effective treatment, it will cause an imbalance in the carbon and nitrogen ratio in the soil, hinder the growth of crops, and even lead to a large number of bacteria and metal ions. Such harmful substances enter the soil and endanger soil and food safety. Garbage aerobic composting refers to the process of mineralizing organic matter and other nutrients in garbage with the help of aerobic microorganisms and generating humus under the condition of sufficien...

AI Technical Summary

Problems solved by technology

At present, the deodorization devices equipped with the rapid garbage fermentation equipment on the market are mostly based on a single biological or chemical reaction principle, such as simple water washing, pickling or alkali washing, and the deodorizing effect is very limited; because the garbage fermentation products are water-containing The powdery humus with a very low rate (<20%), the tail gas generated during the process is often mixed with a large amount of fibrous powder, which is easy to deposit at the elbow when flowing through the pipeline to reduce the wind pressure; in addition, the waste fermentation The process will be accompanied by intense heat release. The temperature of the fermentation tail gas is generally higher than 50°C, much higher than the room temperature, and this part of the heat is generally wasted. This also increases the energy consumption of the garbage rapid fermentation equipment virtually.
