Unit modular large household refuse incineration furnace

Abstract

The invention discloses a unit modular large household refuse incineration furnace and relates to household refuse incineration treatment equipment. The unit modular large household refuse incineration furnace comprises an incineration grate mechanism, air chambers and air supply systems, wherein the incineration grate mechanism comprises a drying section grate, a burning section grate, a burnout section grate and a rack; the drying section grate, the burning section grate and the burnout section grate respectively comprise two groups of grate units; each group of grate units comprises a spindle, a partition plate, a front wall plate, a rear wall plate and a grate with stepped drop; each grate comprises two groups of edge modules and at least one group of middle modules; each edge module and each middle module respectively consist of a plurality of grate sheets; each group of edge modules is fixed on the corresponding rack through a sidewall protection plate device; each air chamber is formed below each middle module and each edge module; an air inlet is formed at the lower end of each air chamber and connected with the corresponding air supply system; and each air supply system comprises a drying section air supply system, a burning section air supply system and a burnout section air supply system. The unit modular large household refuse incineration furnace is stable in operation, low in energy consumption and long in service life.

Description

technical field [0001] The invention relates to domestic waste incineration treatment equipment. Background technique [0002] Garbage incineration is currently the most common garbage treatment method in foreign countries. The biggest advantage of this method is the high degree of garbage recycling and reduction. It has become the main way to deal with domestic garbage in developed countries and an important part of the power industry. In western developed countries, the application of waste incineration technology has a history of nearly 130 years, and it is still considered to be one of the most effective and economical waste disposal technologies. [0003] In recent years, China has independently developed, introduced, digested and absorbed common equipment for waste incineration treatment, and has developed a variety of waste incinerator equipment. Some products have been used in projects, but the performance of the equipment is uneven. [0004] Existing typical me...

AI Technical Summary

Problems solved by technology

[0005] 1) At present, there are many domestic incinerators that can process 100 to 500 tons of waste per day, but there are very few incinerators that can process more than 600 tons of waste per day, which cannot meet the needs of large cities and centralized treatment of domestic waste

[0006] 2) China's waste has high moisture content, high ash content, and complex and intertwined components. The existing waste incinerator feeding equipment has a large load when feeding, and the pushing trolley will generate a large impact when it starts a pushing cycle. The feeding equipment Unstable operation, high energy consumption, short life

[0007] 3) When the garbage is pushed into the incinerator, due to the complex composition of the garbage and it is easy to cluster, the layer of garbage pushed into the incinerator is uneven, the contact between the primary air and the garbage is insufficient, the drying effect of the garbage is poor, and the combustion is incomplete

[0008] 4) The ash leakage of the grate is serious, and the heat reduction rate of the incineration slag is high

[0009] 5) The grate air holes are easily blocked, resulting in uneven air supply
