Environment-friendly treatment and resource utilization system for fine chemical industry kettle residues

Abstract

The invention provides an environment-friendly treatment and resource utilization system for fine chemical industry kettle residues, and belongs to the field of environment protection and waste resource utilization. In the system, a discharging opening of a lifting machine is opposite to a feeding opening of a stock bin, wherein a feeding machine is arranged below the discharging opening of the stock bin; the feeding machine communicates with a heat insulation incinerator through a feeding pipe; the top end of the heat insulation incinerator communicates with a membrane type wall waste heat boiler through a flue; the lower part of the membrane type wall waste heat boiler communicates with a quench tower through a pipeline; the lower part of the quench tower communicates with a bag-type dust remover through a pipeline; the upper part of the bag-type dust remover communicates with the lower part of a deacidification spraying tower through a pipeline; and the top of the deacidification spraying tower communicates with a chimney through a pipeline. According to the system, solid kettle residues are subjected to harmless and reduction environment-friendly treatment, solid kettle residueresource treatment is achieved, heat energy generated by incineration and salt in the kettle residues are recycled, the solid kettle residue environment-friendly treatment standard-reaching discharging requirement is met, the waste resource utilization requirement is met, and enterprise development and environment protection are harmonious and unified.

Description

technical field [0001] The invention belongs to the fields of environmental protection, energy saving and resource utilization of waste, and in particular relates to a system for the environmental protection treatment and resource utilization of fine chemical kettle residues. Background technique [0002] With the rapid development of the national economy, chemical industry, pharmaceuticals, pesticides, building materials, papermaking, printing and dyeing and other industries are developing very rapidly. The types and quantities of chemicals are increasing day by day, and the scale of production equipment is also expanding. The chemical industry is related to all aspects of life. All kinds of items are produced through the chemical industry. With the increasing scarcity of water resources, the increasingly severe environmental problems and the increasing environmental protection requirements, the calls for the development of waste water reuse and zero discharge technologies a...
