Efficient mobile bed gasifier device with pre-dechlorinating function and dechlorinating method of efficient mobile bed gasifier device

Abstract

The invention relates to an efficient mobile bed gasifier device with a pre-dechlorinating function and a dechlorinating method of the efficient mobile bed gasifier device. In a rotary kiln, waste is subjected to drying and pyrolysis and most chlorine of the waste is removed under hot flue gas, after being dechlorinated by using a semi-dry method, separated volatiles and inflammable gas are used as raw material gases to be sent to a turbulent burner for use, the dechlorinated waste is gasified and partially burnt, and the unburnt part of the waste falls on a secondary-level rotary grate device at the rear end, is extruded and crushed and is burnt up after being fully mixed. The erosion to subsequent equipment and the generation of pollutants are greatly reduced, a first-level reciprocation grate adopts a multi-wind port subsection wind distribution mode and achieves the reasonable wind distribution effect, the radiation heat on the grate is increased by a long rear arch, the burning of the waste with low heat value is facilitated, the equipment erosion and environment pollution problems are greatly reduced, the deficiencies of poor mixing and low burn-off rate of the traditional grate incinerator are effectively improved, the area of a high-temperature-resistent grate sheet is reduced, and the investment is reduced.

Description

technical field [0001] The invention relates to a high-efficiency moving bed gasification furnace device with pre-dechlorination function and a dechlorination method thereof. Background of the invention: [0002] At present, incineration is a very effective method of waste disposal, which can maximize the reduction, harmlessness and resource utilization of urban domestic waste. Among the many waste incineration equipment, the grate furnace is a main type of furnace. At present, most of the grate furnaces in our country either learn from the existing incinerators abroad, introduce or imitate foreign furnace types or equipment systems; or use general coal-fired boilers or other industrial furnaces as a reference to transplant these combustion technologies and processes. Carry out waste incineration. However, due to the particularity of waste components in my country and the weak research foundation of grate incineration technology and equipment development, most of the inci...

Problems solved by technology

However, due to the particularity of waste components in my country and the weak research foundation of grate incineration technology and equipment development, most of the incineration grate furnaces in my country currently have many problems, such as: fuel mixing is not good enough, combustion is not sufficient Resulting in lower thermal efficiency, overhaul and maintenance costs of the grate system, etc.

[0003] In addition, due to the complex composition of garbage, pollution problems will inevitably occur during the incineration process
