Sludge blending combustion system for scraper slag fishing machine

Abstract

The invention relates to the field of thermal power generation, and particularly relates to a sludge blending combustion system for a scraper slag fishing machine. According to the system, a slag fishing chamber is located below a boiler furnace, the bottom of the boiler furnace communicates with the top of the slag fishing chamber, the scraper slag fishing machine is located in the slag fishing chamber, high-temperature slag generated by combustion of the boiler furnace falls into the slag fishing chamber under the action of gravity so as to be temporarily stored and soaked for cooling, a waste gas source sucks dirty exhaust gas in a sludge treatment workshop and sprays the exhaust gas out through a nozzle arranged in the slag fishing chamber so as to meet an air inlet requirement of thebottom of the boiler furnace, the gas spraying amount of the nozzle is controllable and convenient to measure, and meanwhile, the exhaust gas sprayed by the nozzle can also cool liquid in the scraperslag fishing machine and heat is sent back to the boiler furnace so as to reduce the liquid temperature in the scraper slag fishing machine.

Description

technical field [0001] The invention relates to the field of thermal power generation, in particular to a sludge blending combustion system used in a scraper slag extractor. Background technique [0002] Sludge is a kind of high water content floc composed of various microorganisms and organic and inorganic particles. It is enriched with impurities and salts in the raw water treatment process. Some pollutants can dissolve in water and cause water pollution. Contains a large amount of toxic and harmful substances, if not handled properly, it will cause great damage to the human body and the ecological environment. At present, the commonly used sludge treatment methods include landfill, composting and incineration, etc., and landfill is the main method. The pollution caused by non-standardized sludge treatment and the problem of "secondary pollution" are becoming more and more serious. [0003] Coal-fired thermal power generation is currently the most important form of power ...
