A waste heat power generation system for industrial hazardous waste disposal industry

Abstract

The invention provides a waste-heat power generation system used in the industrial hazardous waste disposal industry. The waste-heat power generation system comprises a combustion system and an organic working medium power generation system, wherein the combustion system comprises a combustion mechanism, a waste heat boiler and a fuel gas treatment system; the high-temperature fuel gas output opening of the combustion mechanism is connected with the high-temperature fuel gas input opening of the waste heat boiler; the organic working medium power generation system comprises an organic working medium evaporator, an organic working medium power generator, an organic working medium cooling system, an organic working medium pump and a condensation water pump which are sequentially connected; and the fuel gas treatment system comprises a quench tower, a dust remover, an induced draft fan and a chimney which are sequentially connected. By adopting the waste-heat power generation system, heat energy of boiler steam can be directly recycled for heating an organic working medium; the organic working medium power generator is driven to work for power generation, so that comprehensive utilization of resources is realized; power consumption of enterprises is reduced; and economic benefit of the enterprises is increased.

Description

technical field [0001] The invention relates to the field of hazardous waste disposal, in particular to a waste heat power generation system used in the industrial hazardous waste disposal industry. Background technique [0002] With the development of industry, the hazardous waste discharged from industrial production process is increasing day by day. It is estimated that 330 million tons of hazardous waste are generated worldwide each year. Hazardous waste will bring serious pollution and potential impact on the environment. After long-term research and practice, researchers have developed different disposal methods for hazardous waste, including physical treatment, chemical treatment, biological treatment, and high-temperature heat treatment. and solidification treatment. Among them, the high-temperature heat treatment method generally refers to the incineration method, that is, the oxidative combustion reaction is carried out with the organic waste to be treated in the...

Problems solved by technology

However, the boiler steam pressure and steam volume produced by the industrial hazardous waste incineration mechanism are low, so it is not suitable to be equipped with a steam turbine generator. The current disposal method is generally air cooling, that is, the boiler steam is cooled by an air cooler to form water, recycled back to the boiler

This cooling process dissipates a large amount of heat energy directly into the air, not only the heat energy is not effectively utilized, but also a large amount of electric energy needs to be provided for the air cooler, resulting in serious energy waste
