Sludge mixed combustion system used for dry type slag extractor

Abstract

The invention relates to the field of thermal power generation, in particular to a sludge mixed combustion system used for a dry type slag extractor. A boiler furnace, a transition slag bucket and thedry type slag extractor are arranged from top to bottom in sequence. The bottom of the boiler furnace communicates with the top of the transition slag bucket. High-temperature furnace slag produced by combustion of the boiler furnace falls into the transition slag bucket for temporary storage under the effect of gravity, a waste gas source sucks contaminated waste gas in a sludge treatment plant,and the waste gas is sprayed out through spray nozzles arranged in the transition slag bucket, so that gas inlet requirements of the bottom of the boiler furnace are met; in addition, the gas spray amount of the spray nozzles is controllable and is convenient to calculate, meanwhile, the waste gas sprayed out of the spray nozzles can further cool the high-temperature furnace slag, and heat is sent back to the boiler furnace; and partition doors are arranged between the transition slag bucket and the dry type slag extractor, open at a preset frequency and release the furnace slag in the transition slag bucket into the dry type slag extractor, and therefore, slag of the boiler furnace is discharged.

Description

technical field [0001] The invention relates to the field of thermal power generation, in particular to a sludge blending combustion system for a dry slag discharger. 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 generat...
