High-efficiency and pollution-free waste incineration power generation environmental protection supporting device and its application process

Abstract

The invention relates to the technical field of refuse incineration power generation and particularly discloses an environment-friendly device matched with efficient and pollution-free refuse incineration power generation and a using technology of the environment-friendly device matched with efficient and pollution-free refuse incineration power generation. On the basis of an existing refuse incineration power generation system, a pre-treatment system, a flue gas treatment system and a leachate treatment system are additionally arranged. The pre-treatment system comprises a scratching machine, a sorting system, a magnetic separator, a crusher and a dehydrator. The flue gas treatment system comprises a bag type dust collector and a wet type dust collector, and a slag outlet of the bag type dust collector is provided with a flue dust collecting system. A leachate adjusting pool is sequentially connected with a convectional biochemical-physicochemical treatment system, an electrocatalytic oxidation pool and a membrane biological reaction pool. Through the environment-friendly device matched with efficient and pollution-free refuse incineration power generation and the using technology of the environment-friendly device matched with efficient and pollution-free refuse incineration power generation, generation of dioxin precursors is greatly reduced or even eliminated, and therefore first, pollution is reduced, and second, waste treatment cost is reduced and the national emission standard can be reached. The environment-friendly device matched with efficient and pollution-free refuse incineration power generation has prominent innovation, the generating capacity is improved by more than 1.5 times, and the tough problem of environmental pollution is solved comprehensively and thoroughly.

Description

technical field [0001] The invention relates to the technical field of waste incineration power generation, in particular to a high-efficiency and pollution-free waste incineration power generation environmental protection supporting device and its use process, wherein the environmental protection specifically belongs to the waste water, waste gas and solid waste treatment technology in environmental engineering. Background technique [0002] The commonly used method abroad is to incinerate most of the waste for power generation and a small part to landfill. As early as the 1990s in China, it was established as a national 863 project. After 2000, major provincial capitals and cities above the middle-level in the economically developed eastern regions generally promoted incineration power generation. It is a well-known fact that the supporting environmental protection technology issues have not been fully and perfectly resolved. appears in: [0003] First, the sensitive iss...
