Waste gas treating system

Abstract

The invention discloses a waste gas treating system for treating waste gas produced in tobacco leave threshing and redrying processes. The waste gas treating system comprises a spray chamber, a settling water-storage tank and a dewatering tower, wherein a smog passage is formed in the spray chamber; a smog inlet and a smog outlet are respectively formed in the front end and the rear end of the smog passage; more than one row of spray nozzles are arranged along the smog passage; a water outlet is formed in the bottom of the smog passage; the smog inlet is communicated with the damp outlets of a tobacco leave redryer and a tobacco stem redryer through pipelines; the smog outlet is communicated with a gas inlet of the dewatering tower through a pipeline; the settling water-storage tank is provided with a water pump; a water inlet of the water pump is communicated with a spray liquid in the settling water-storage tank; a water outlet of the water pump is communicated with the spray nozzles through pipelines; a reflux hole is formed in the bottom of the settling water-storage tank; the reflux hole is communicated with the water outlet of the smog passage through a pipeline; multiple adsorption layers are arranged between the gas inlet and a gas outlet in the dewatering tower; the gas outlet of the dewatering tower is communicated with an external boiler chimney through a fan.

Description

technical field [0001] The invention relates to tobacco leaf threshing and redrying processing equipment, in particular to a waste gas treatment system used in the tobacco leaf threshing and redrying process. Background technique [0002] With the continuous development of industrial production, social wealth and people's economic income are increasing. At the same time, various industrial productions also bring about many social problems, and environmental pollution is one of the most important ones. The tobacco odor produced by threshing and redrying is a kind of exhaust gas pollution. Tobacco belongs to leaf economic crops, and tobacco leaf itself has a special taste. In the process of production and processing, due to the needs of the processing technology, a certain amount of exhaust gas pollution will be generated. The exhaust gas from tobacco leaf processing has a distinct odor. The impact of smoke emission on the environment is significant. At present, the compos...

AI Technical Summary

Problems solved by technology

The impact of smoke emission on the environment is significant. At present, the composition and nature of tobacco odor are not completely clear

At the same time, there are no relevant reports on the treatment of odor pollution from tobacco redrying factories. Only some cigarette factories have equipment and facilities for this treatment. The treatment methods mainly include spray absorption, bubble decomposition, and biochemical adsorption degradation. , thermal decomposition, catalytic oxidation and plasma technology, etc., and a considerable part of them adopts imported equipment, facilities and processing technology
