Treatment method for biological decayed off-gas

Abstract

The invention provides a treatment method for biological decayed off-gas, comprising the steps of: enabling the off-gas to pass through a cooler to cool part of off-gas to form a liquid, discharging the liquid into a sewage plant, flowing the residual off-gas to a spraying device under the action of a draft fan, partially absorbing and filtering the residual off-gas in the spraying device, discharging a sprayed mixed liquid into the natural world from the bottom of a spraying room by a pipeline, enabling the off-gas unabsorbed after spraying to flow to a furnace from the upper part of the spraying room by the pipeline under the action of the draft fan, combusting the off-gas entering the furnace in the furnace completely, enabling the off-gas to combust and convert into non-toxic gas, and finally discharging the gas checked to reach the standard in the non-toxic gas in carbon dioxide and steam generated in the furnace into the atmosphere to finish the whole process of treating the biological decayed off-gas instantly. The treatment method is simple in operation and capable of effectively decomposing and absorbing the biological decayed off-gas and achieving the goal of deodorizing.

Description

technical field [0001] The invention relates to a method for treating the polluted gas produced by deterioration of marine biological products in the production process. Background technique [0002] The waste gas generated during the production of marine biological products accumulates and rots. The waste gas not only has a foul smell, but also contains toxic gases, such as hydrogen sulfide, sulfur dioxide, ammonia, etc. The waste gas not only pollutes the air, but also affects the lives of surrounding residents. . [0003] An existing Chinese invention patent application with the application number CN201010232979.7 titled "Combined Bio-fermentation Waste Gas Treatment Device and Method" discloses a combined biological fermentation waste gas treatment device and method, which includes pre-treatment of biological waste gas and There are two steps for biological waste gas treatment. The pre-treatment of biological waste gas uses a pre-gas-liquid separator to dehumidify the b...

[0003] An existing Chinese invention patent application with the application number CN201010232979.7 titled "Combined Bio-fermentation Waste Gas Treatment Device and Method" discloses a combined biological fermentation waste gas treatment device and method, which includes pre-treatment of biological waste gas and There are two steps for biological waste gas treatment. The pre-treatment of biological waste gas uses a pre-gas-liquid separator to dehumidify the biological fermentation waste gas, then uses a gas filter to remove impurities from the biological fermentation waste gas, and finally uses a spray tower to carry out this process. The cooling treatment of biological fermentation waste gas is enough, and the biological waste gas treatment uses biological waste gas processor and / or plasma waste gas processor to treat the biological fermentation waste gas that has undergone the aforementioned biological waste gas pretreatment operation, but this method treats the waste gas The steps are cumbersome, the process is more complicated, and the effect is not very satisfactory, so this treatment method needs to be further improved
