Multiple row sectional drive combined type domestic garbage incinerator

Abstract

The invention relates to multi-column sectional drive combined type domestic incinerator. It is set three fire-grates that drying section, burning section, and firing section. The middle fire grate is connected between them. There is altitude fall between them that the drying section is the highest point; the firing one is the lowest point. The primary air chamber is respectively set under them. The incinerator fire grate system of the invention has independent drive mechanism, air supply system, and air chamber for each section which is convenient for controlling technical parameter that traveling speed, air quantity, air temperature, air pressure etc to realize full drying and burning for whole garbage layer.

Description

technical field [0001] The invention relates to a device for incineration treatment of solid waste, in particular to a multi-column, section-driven compound domestic waste incinerator. Background technique [0002] The current waste treatment technologies are basically divided into incineration, sanitary landfill, composting, waste recycling and so on. Among the conventional waste treatment technologies, incineration has the advantages of obvious reduction effect, complete harmlessness, small land occupation, utilization of waste heat energy, and less secondary pollution, which meets the strategic requirements of sustainable development in my country's more economically developed areas. [0003] Among the existing incineration processes and equipment, the grate type incinerator has various forms, and its application accounts for more than 80% of the total waste incineration market in the world. Among them, the most widely used is the Martin type reciprocating grate incinera...

AI Technical Summary

Problems solved by technology

[0005] 1. When pushing the garbage into the incinerator, due to the operation failure of the feeder or the composition of the garbage, the garbage entering the incinerator grate is sometimes small in size, sometimes very large in size, and the gap between the garbage The degree of looseness and density varies greatly, which is not conducive to the full drying and burning of garbage

[0006] 2. Due to the low calorific value and high moisture content of Chinese garbage, the garbage is not dried before entering the grate, and the leachate in the garbage will enter the grate together with the garbage, and the leachate will easily block the blower in the grate Road and corrosion of the grate will not only affect the stability of garbage combustion and heat generation, but also cause the grate to malfunction, thereby affecting the service life of the grate

The grate only stirs and loosens the garbage in the longitudinal direction, and has no obvious effect on the garbage material layer in the horizontal direction, and has no obvious effect on the stirring and loosening of the entire garbage material layer

Therefore, it is not possible to fully turn over, stir and loosen the entire garbage material layer to shorten the drying time and improve the combustion efficiency

[0009] 5. Due to the high water content and complex composition of domestic waste in China, it is easy to form lumps and lumps when the waste is dried and burned
