Problems solved by technology

However, the use of a water-cooled slag remover also brings the following problems: the slag after water cooling contains moisture, and when the ash is recycled (for example, the slag is used as a raw material into the cement kiln system), it needs to be dried first, which will consume More heat; the water-cooled slag machine needs to consume a large amount of cooling water, and also requires a separate circulating water treatment system with strict sealing requirements, which has high maintenance costs; the water vapor generated when cooling the slag enters the garbage incinerator, affecting the waste. The stability of the incineration system reduces the service life of the refractory materials of the waste incineration device; the wear and deformation of the water-cooled slag machine are large, which often leads to problems such as failure and shutdown, which affects the stable operation of the incinerator system

Abstract

The invention provides an air cooling deslagging device. The air cooling deslagging device comprises a cooling chamber body, and further comprises an air chamber with an air inlet, wherein a cooling grid plate is arranged at the bottom of the cooling chamber body; the air chamber is arranged under the cooling grid plate; a feed inlet and an air waste heat outlet are formed in the top of the cooling chamber body; a discharge opening is formed in one side of the cooling chamber body; the cooling grid plate is a movable grid plate which can drive ash to move frontwards; or, the cooling grid plate is fixed; and a material pushing device is arranged above the cooling grid plate. In the technical scheme, air is utilized as a cooling medium, various defects caused by adoption of water cooling can be avoided, cost is reduced, and reutilization of ash is facilitated; hot air generated after cooling can be recycled and reutilized in multiple application; and on structure, the material pushing device can adopt hydraulic or mechanical transmission and can still stably and reliably operate in various complex working conditions.

Description

technical field [0001] The invention relates to the technical field of waste incineration, in particular to an air-cooled slag discharging device which cools the ash generated after waste incineration with air. Background technique [0002] In the field of waste incineration, water cooling is currently used to cool the slag after waste incineration. The water used for water cooling can not only cool the slag, but also keep the entire incineration system airtight. However, the use of a water-cooled slag remover also brings the following problems: the slag after water cooling contains moisture, and when the ash is recycled (for example, the slag is used as a raw material into the cement kiln system), it needs to be dried first, which will consume More heat; the water-cooled slag machine needs to consume a large amount of cooling water, and also requires a separate circulating water treatment system with strict sealing requirements, which has high maintenance costs; the water v...
