Embodiment 1

[0033] The pulverizer breaks up the coal and solid waste, and the mixer dilutes the viscous waste liquid and mixes it evenly. The coal-solid waste-waste liquid is in a specific mass ratio of (1-12):(2-7):(1-4) It is made into a regular shape in the granulator and is hydraulically pushed to the kiln head of the rotary furnace.

Embodiment 2

[0035] The crusher breaks up the coal and solid waste, and the mixer dilutes the viscous waste liquid and mixes it evenly. The coal-solid waste-waste liquid has a specific mass ratio of (1-12):(7-13):(4-7) It is made into a regular shape in the granulator and is hydraulically pushed to the kiln head of the rotary furnace.

Embodiment 3

[0037] The pulverizer breaks up the coal and solid waste, and the mixer dilutes the viscous waste liquid and mixes it evenly. The coal-solid waste-waste liquid has a specific mass ratio of (1-12):(13-19):(7-10) It is made into a regular shape in the granulator and is hydraulically pushed to the kiln head of the rotary furnace.

Abstract

The invention relates to a gas, solid and liquid integrated combustion system, and belongs to the technical field of the environment. The system is composed of a waste gas collection system, a granulation system, a feeding system, a rotating furnace, a combustion furnace, a waste heat boiler, a heat exchanger, a rapid quenching tower, a smoke dry type washing system, a cloth bag dust removal device, a spray tower, a reheater and a chimney. Coal, solid waste and liquid waste are evenly mixed according to the mass ratio (1-12):(2-30):(1-16) in the granulation system for granulation; after collected waste gas is preheated, part of the waste gas enters the rotating furnace, and the other part of the waste gas enters the combustion furnace to be processed through high temperature combustion; high temperature tail gas of the combustion furnace enters the rapid quenching tower, the dry type washing system, the cloth bag dust removal device and the spray tower after heat energy recovery, and is sent to the chimney by a draught fan after the tail gas is cooled and fly ash, dioxin and acid gas are removed, so that emission reaching the standard is completed. Liquid waste produced in the running process of the system is recycled in the granulation system, solid waste such as activated carbon is fed into the rotating furnace to be combusted, and therefore harmless treatment is achieved while running cost of the system is reduced.

Description

technical field [0001] The invention relates to a gas-solid-liquid integrated incineration system, in particular to an integrated incineration system for the treatment of three wastes in the pharmaceutical industry, and belongs to the field of environmental technology. Background technique [0002] With the continuous development of the domestic economy, the emission of organic volatile gases VOCs in chemical, pharmaceutical, spraying and other industries is increasing day by day, which has a significant impact on air quality and has become one of the main sources of air pollution. VOCs gases include hydrocarbons, aldehydes, benzenes, esters, halogenated hydrocarbons and aromatic hydrocarbons, etc., which have the characteristics of many types of emissions, large differences in properties, complex processes and working conditions, and a wide range of sources. VOCs gas will reduce human immunity, affect the central nervous system, cause human discomfort, coma, and even cause ...
