A preparation system and operation method of solid recovered fuel

Abstract

The invention provides a solid recovery fuel preparation system and a running method thereof, wherein light combustible substances, heavy incombustible substances and recoverable metals can be separated while the moisture content of domestic garbage can be reduced and the calorific value of the garbage can be increased. According to the method, garbage enters a coarse breaking machine by a sortingline material receiving hopper, and the coarse breaking machine breaks the domestic garbage; the coarsely broken garbage is conveyed to a dish-type sieve by a coarse breaking machine material discharge belt conveyor, and before the garbage enters the dish-type sieve, part of the iron metal carried in the garbage is removed by a dish-type sieve feeding pre-iron removing device; the domestic garbage is sieved into an oversize material and an undersize material; the light combustible substances in a light substance buffer warehouse are fed to a drying line material receiving hopper by a substance buffer warehouse bridge type grab crane, and then the light combustible substances are conveyed to a drying machine by a double screw conveyor; and the light combustible substances being subjected to air drying treatment is conveyed to a solid recovery fuel warehouse by a finished product fuel warehousing conveyor.

Description

technical field [0001] The invention relates to a solid recovery fuel preparation system and an operation method thereof, which are mainly used in domestic waste resource treatment plants or waste incineration power plants. Background technique [0002] With the development of economy and society and the improvement of material consumption level, the output of domestic waste in our country has increased rapidly, resulting in more prominent environmental hazards. Through garbage classification, not only can the reduction and recycling of garbage be realized, but also domestic garbage can be turned into treasure, which is conducive to sustainable development; it can also improve the efficiency of subsequent garbage treatment and reduce the difficulty of treatment. [0003] At present, my country's garbage source classification is in the initial stage, and the response level varies greatly from place to place. From the perspective of popularization, domestic waste generated by ...

AI Technical Summary

Problems solved by technology

These domestic wastes generally have problems of high moisture content, low calorific value, and complex components, which lead to a high failure rate of equipment in domestic waste incineration plants. At the same time, boiler efficiency is low, power generation is small, economical is poor, and environmental protection standards are high. Discharge pressure , which is not conducive to the effective use of domestic waste as a renewable energy source
