Problems solved by technology

[0003] At present, the incinerators used in domestic solid incineration treatment use fuel oil or gas as auxiliary fuel. This treatment method has high operating costs, incomplete incineration effect, and uneven furnace temperature, which is prone to local overheating. In addition , the heat generated by incineration has not been recycled, resulting in a waste of energy resources

Abstract

The invention relates to the field of coal chemical industry solid treatment, in particular to a coal chemical industry solid slag recycling system. The coal chemical industry solid slag recycling system comprises a smashing furnace, a middle furnace and an incineration furnace; the smashing furnace is arranged above the middle furnace, the incineration furnace is arranged below the middle furnace, the smashing furnace comprises a spiral conveyor, a grinding roller, a rotating mechanism, a bearing, a damping spring II and a smashing furnace shell, the middle furnace comprises a shaking plate,a spring I, an air bag, a spring II, a gas conveying pipe, an elastic ring support and a storage wheel, and the incineration furnace comprises a water tank, a steam conveying pipe, a hydrargyrum sealbox I, an automatic water outlet device, a hydrargyrum seal box II and a safety valve. The coal chemical industry solid can be sufficiently combusted, heat generated by combustion can be used, large-scale waste heat recycling is achieved, and the system is an effective manner for repeatedly using coal chemical industry solid resources and improving the energy use rate.

Description

technical field [0001] The invention belongs to the field of coal chemical solid treatment, in particular to a coal chemical solid slag recovery and reuse system. Background technique [0002] For the treatment of coal chemical solids, the traditional mainstream storage and landfill disposal methods can no longer meet the national requirements for environmental protection and sustainable development, and there are certain environmental hazards and risks of occupying a large amount of land resources and polluting groundwater. The resource utilization and reduction treatment of chemical solid waste has become one of the environmental protection problems that need to be solved urgently. Coal chemical solid incineration technology is a kind of thermochemical treatment technology, which can realize the recovery and reuse of thermal energy resources. This technology has many advantages, such as good volume reduction effect, basically completely harmless, large-scale waste heat re...
