Microwave-assisted pyrolysis gasifier and waste pyrolysis gasification incineration method

Abstract

The invention discloses a microwave-assisted pyrolysis gasifier. The microwave-assisted pyrolysis gasifier mainly comprises a first combustion chamber and a second combustion chamber. The first combustion chamber is divided into a drying region, a pyrolysis gasification region, a combustion region and a burnout region. A microwave transmitter is arranged in the drying region, and multiple regional hearths are arranged in the second combustion chamber. Through the unique structure arrangement, the efficient and reasonable drying, pyrolysis gasification and combustion of waste are achieved, the efficient treatment of the waste is achieved, and the generation and discharge of the waste are reduced. The invention further provides a waste pyrolysis gasification incineration method, mutual independence, complement and promotion of waste drying, pyrolysis gasification, combustion, burnout, flue gas combustion and the like are achieved, the efficient operation of the waste pyrolysis gasification incineration is achieved, and the problems of waste gas pollution and the like are solved effectively.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a microwave-assisted pyrolysis gasification furnace and a method for pyrolysis gasification incineration of garbage. Background technique [0002] At present, most of the domestic waste pyrolysis furnaces on the market do not have an external energy intervention process, and only rely on the calorific value of the waste itself to maintain the operation of the pyrolysis gasification process. However, the composition of domestic waste is very complex and ever-changing. The value also changes accordingly, especially in continuous rainy weather, the increase of garbage moisture will lead to a significant decrease in the calorific value of the garbage, which often leads to a decrease in the furnace temperature, and the process technical parameters of the system are unstable, which seriously affects the treatment effect and efficiency of the garbage. [0003] A small number o...

Problems solved by technology

However, limited by the process and structure, this method of heating with an open flame can only be set in the combustion chamber. This kind of intervention point is not ideal in the position and period of the entire treatment process route (or treatment procedure), and the treatment effect is correspondingly unsatisfactory. ; In addition, while the diesel burner burns and releases heat, it also produces a certain amount of harmful exhaust gas, which increases the processing difficulty and load of the exhaust gas purification system at the back end
