Multi-stage purification treatment system for exhaust gas from carbonization of pottery making from river and lake bottom mud

Abstract

The invention provides a multi-stage purification treatment system for exhaust gas from river and lake bottom mud carbonization for pottery making. The multi-stage purification treatment system includes a multi-tube pulse bag plus cyclone dust removal system connected to the exhaust gas output pipeline, which is connected to the multi-tube pulse bag plus cyclone dust removal system, and a rapid cooling and condensation system for rapidly cooling the tail gas. The photocatalyst catalytic system connected to the rapid cooling condensing system, the biological spray system connected to the photocatalyst catalytic system, the activated carbon adsorption filter system connected to the biological spray system, and the activated carbon adsorption filter system connected to the discharge Negative pressure fan and distributed exhaust device for clean exhaust gas.

Description

technical field [0001] The invention belongs to the technical field of tail gas treatment, and in particular relates to a multi-stage purification treatment system for the tail gas of river and lake bottom mud carbonization for pottery making. Background technique [0002] River and lake polluted sediment is a kind of solid waste produced in the process of urban sewage treatment. It is rich in pathogens, microorganisms, etc., and is very harmful to the environment. Improper treatment can easily cause secondary pollution. There is a large amount of polluted sediment from rivers and lakes in my country, and the main treatment and disposal methods are landfill, land use and a small amount of incineration. These treatment methods, on the one hand, cannot fundamentally reduce the content of harmful substances, and are likely to cause secondary ecological environmental pollution. On the other hand, the polluted sediment from rivers and lakes has not been effectively utilized. [...
