Water-cooled reciprocating-type multi-stage hydraulic mechanical grate furnace and control method thereof

Abstract

The invention relates to a water-cooled reciprocating-type multi-stage hydraulic mechanical grate furnace and a control method of the grate furnace, wherein the grate furnace comprises a feeding grate, a burning grate, a primary wind supply system and a secondary wind supply system; the burning grate is divided into five units in the vertical direction, and each unit consists of a plurality of water-cooled grate plates, the grate plates in each row are driven along the transverse direction by a shaft, and supported on at least three places in the transverse direction by a steel frame. With the adoption of the method, the temperature of the grate plates is more uniform, the practicability is wider after the water-cooling pipe is added, and the burning rate is further enhanced on the basis of the more accurate controls over the grate plate, the temperature and the wind supply system.

Description

technical field [0001] The invention relates to the field of incinerators, in particular to a water-cooled reciprocating multi-stage hydraulic-mechanical grate furnace and a control method thereof. Background technique [0002] Waste incineration is one of the main ways to realize waste reduction, harmless and resourceful treatment. At present, garbage incineration has gradually become the main way of garbage disposal. After modern incineration, the volume of garbage can generally be reduced by 80%-90%. At the same time, various pathogens can be eliminated, harmful substances can be converted into harmless substances, and resources can also be realized. use. Due to the different types of waste, it can be divided into domestic waste, high calorific value domestic waste, industrial waste, and medical waste. In the process of incinerating waste, the water content of each type of waste and the calorific value produced after incineration are different. Different incinerators ar...

AI Technical Summary

Problems solved by technology

[0013] Aiming at the deficiencies of the prior art, the present invention provides a water-cooled reciprocating multi-stage hydraulic-mechanical grate furnace and its control method. The grate furnace can be applied to biomass, high calorific value domestic waste, industrial waste and medical waste. In order to improve the problem that the existing incinerator does not have water cooling equipment, realize the cooling of the grate, reduce the loss of the grate, and solve other problems existing in the operation of the current grate furnace
