Environmentally friendly discharge treatment system for industrial waste liquid

Abstract

The invention provides an industrial waste liquid environment-friendly discharge treatment system. The waste liquid sprayed in a vapor state sufficiently contacts high-temperature rotatable-ascending flue gas in a combustion furnace, the moisture in the waste liquid is heated and evaporated, and most toxic and harmful substances in the waste liquid are completely combusted and burnt out at high temperature to generate abundant smoke dust, CO2, waste smoke composed of various corresponding acidic gases, and exhaust gas, which are subsequently subjected to neutralization deacidification, dehydration, adsorption and dust removal treatment by a tail gas treatment system composed of a quenching neutralization absorption tower, a deacidification adsorption unit, a bag-type dust collector and a water-circulation deacidification dust-removal washing tower, thereby finally satisfying Chinese Standard GB18484-2001 (Hazardous Waste Incineration Pollution Control Standard). The overall system has the advantages of thorough combustion, completely harmless tail gas treatment and stable operation, and can effectively control and lower the operating cost.

Description

technical field [0001] The invention belongs to the technical field of industrial waste treatment, and in particular relates to an environment-friendly discharge treatment system for industrial waste liquid. Background technique [0002] With the continuous development of the industrial economy, a large amount of industrial waste cannot be disposed of in time. Most of the industrial waste is in the form of solid waste and liquid waste. The industrial waste liquid contains a large amount of toxic and harmful substances, arsenic, copper, and chromium. , mercury and other heavy metals, improper handling will cause irreversible damage to the surrounding soil environment and atmospheric environment. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides an environmentally friendly discharge treatment system for industrial waste liquid, which burns the waste liquid and performs a series of combustion waste gas ...
