Fixed grate capable of suspending and moving garbage

Abstract

The invention relates to a fire grate, in particular to a fixed grate capable of suspending and moving garbage. The fixed grate comprises a grate body, wherein the grate body is sequentially divided into a drying region, a combustion region and an after-combustion region from left to right; the front end of the grate body is equipped with a combustion-supporting hot air tube; the combustion-supporting hot air tube separately communicates with the drying region, the combustion region and the after-combustion region through an air supplementing pipeline with an air supplementing valve; a compressed air pipeline is arranged at the rear end of the grate body; and the compressed air pipeline separately communicates with the drying region, the combustion region and the after-combustion region through a buffer tank and a pulse tube. The grate is of a fixed type, is easily manufactured, is low in manufacturing cost, is reliable in operation, is high in combustion thermal efficiency, is low inoperation and maintenance cost, is high in reliability and is strong in practicability.

Description

technical field [0001] The invention relates to a fire grate, in particular to a fixed fire grate capable of suspending and moving garbage. Background technique [0002] When incinerating waste, it is usually treated with an incinerator. At present, the relatively mature furnace types on the market include mechanical grate incinerators, fluidized bed incinerators, and rotary kiln incinerators. However, these common incinerators all have certain deficiencies, such as high requirements for the material and machining accuracy of the grate of the mechanical furnace, complex mechanical structure, high damage rate, and large maintenance. The high cost and maintenance cost of the grate furnace make it difficult to popularize and apply. The fluidized bed incinerator has sufficient combustion and good combustion control in the furnace, but the amount of dust in the flue gas is large, the operation is complicated, the operating cost is high, and the requirements for the uniformity of...

However, these common incinerators all have certain deficiencies, such as high requirements for the material and machining accuracy of the grate of the mechanical furnace, complex mechanical structure, high damage rate, and large maintenance

The high cost and maintenance cost of the grate furnace make it difficult to popularize and apply

The fluidized bed incinerator has sufficient combustion and good combustion control in the furnace, but the amount of dust in the flue gas is large, the operation is complicated, the operating cost is high, and the requirements for the uniformity of the fuel particle size are high, and a high-power crushing device is required. The equipment is seriously worn out and requires a lot of maintenance

Rotary kiln incinerators are expensive, difficult to control combustion, and difficult to burn when the calorific value of waste is low
