Large-capacity garbage high-temperature gasification spraying combustion system

Abstract

The invention discloses a large-capacity garbage high-temperature gasification spraying combustion system comprising a furnace body base. A drying section furnace body and a spraying combustion section furnace body are arranged on the furnace body base. The spraying combustion section furnace body comprises a spraying combustion main furnace body. A spraying combustion rotational flow hearth is arranged in the spraying combustion main furnace body. Spraying combustion top spraying openings embedded in a fireproof material layer are formed in the top wall of the spraying combustion rotational flow hearth, and spraying combustion outer side spraying openings embedded in the fireproof material layer are formed in the side wall of the spraying combustion rotational flow hearth. The spraying combustion top spraying openings and the spraying combustion outer side spraying openings are formed in the spraying combustion rotational flow hearth, so that two combustion vortexes are formed in the spraying combustion rotational flow hearth, particles and components which are incomplete in gasification combustion are mixed and combusted fully, the temperature of the combustion vortexes can reach 1200-1300 DEG C, dioxin is also decomposed completely at the stage, and combustion is more fierce; and the large-capacity garbage high-temperature gasification spraying combustion system is a breakthrough technological progress of the garbage incineration technology and has great economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of energy utilization, in particular to a waste energy release utilization system that injects heat energy after gasification and combustion to a heat energy collection and utilization system. Background technique [0002] Municipal solid waste incineration power generation has the three advantages of harmlessness, resource utilization and reduction, which plays a major role in improving urban sanitation and environment. It is an optimal way to deal with municipal solid waste today and has become the best way to deal with urban solid waste in my country. One of the main methods. At present, the thermal efficiency of most waste incineration power generation boilers in China is low, which directly affects the economic benefits of waste incineration power plants. The stable combustion control and adjustment of waste incineration power generation boilers are the key points and difficulties in operation. Engineer...

Problems solved by technology

Since the combustion process of garbage on the grate starts from the bottom layer, it enters five stages of drying, volatile analysis, volatile matter combustion, coke combustion and slag burnout, and the separated volatile matter is directly discharged into the waste gas after the volatile matter is burned. To the boiler heat exchanger, it is discharged after heat exchange. During this process, the flue gas contains unburned volatiles, dioxins and other components. Unburned volatiles cause energy waste, and dioxins cause environmental pollution. Therefore, the defect of the working principle of waste incineration power generation in the prior art has caused major technical problems, the emission of harmful gases, especially dioxins, cannot be eliminated, the energy loss is serious, and the environment is polluted and poisoned
