Waste heat recovery deslagging equipment and method for garbage fly ash plasma furnace zone

Abstract

The invention belongs to the technical field of deslagging equipment, and particularly relates to waste heat recovery deslagging equipment and method for a garbage fly ash plasma furnace zone. The equipment comprises a pre-cooling table, a slag cooling pool, a slag conveying device and a frame body, wherein the pre-cooling table is rotatably connected with the frame body; the pre-cooling table is connected with a driving mechanism, and the driving mechanism drives the pre-cooling table to rotate; a sealing cover is fixed above the pre-cooling table, and the sealing cover is rotationally connected with the pre-cooling table; a scraping plate is arranged in the sealing cover, and the slag cooling pool is located below the pre-cooling table and fixedly connected with the frame body; the slag conveying device is fixedly connected with the slag cooling pool, and materials in the slag cooling pool can be discharged or discharged to the pre-cooling table through the slag conveying device; slag on the pre-cooling table is scraped into the slag cooling pool through the scraping plate; and a slag inlet is formed in the sealing cover. A high-temperature melt is prevented from being solidified on the equipment while the melt is cooled, continuous deslagging cooling can be achieved, and the cooling temperature is controllable. The equipment is provided with a waste heat recovery device and has the advantages of being low in energy consumption and low in water consumption.

Description

technical field [0001] The invention belongs to the technical field of slagging equipment, and in particular relates to a slagging equipment and method for waste heat recovery of a waste fly ash plasma furnace belt. Background technique [0002] Domestic waste incineration technology has developed rapidly in the past two years due to its advantages of fast processing speed, easy pollution prevention and control, high technical reliability, and easy project implementation. As of 2018, waste incineration accounted for more than 30% "2018 China Urban Construction Statistical Yearbook", the rapid development of waste incineration has led to a large amount of waste fly ash in the past two years. Since garbage fly ash contains more heavy metals, dioxins and other toxic and corrosive substances, the harmless disposal of garbage fly ash has become one of the difficulties in domestic waste incineration technology. [0003] The high-temperature plasma furnace for waste incineration f...

Problems solved by technology

[0004] Some high-temperature slagging equipment of plasma furnaces are disclosed in existing patent documents, such as: the method for plasma enhanced cracking of organic waste disclosed by patent application number CN200310113485.7 and the plasma furnace; the patent application number is disclosed by CN201811325471.4 A plasma device for treating medical waste; the patent application number is CN201811325676. A plasma device for treating oil sludge is disclosed; in the above devices, the slag liquid is directly discharged into the water cooling pool, and this method of cooling slag 10 consumes a lot of water , while the cooling rate cannot be controlled

[0005] The patent application number is CN202011388864.7, which discloses a plasma furnace continuous slagging device and continuous slagging method that can discharge materials continuously. This scheme can meet the requirements of continuous slagging to a certain extent; this scheme has no pre-cooling section and The waste heat recovery device directly puts the melt into the cooling liquid, but there is still the problem of large water consumption
