Slag cooler for utilizing and recycling waste heat of slag

Abstract

The invention discloses a slag cooler for slag waste heat utilization and recovery. The slag cooler comprises an outer shell mechanism and an inner shell mechanism installed in the outer shell mechanism. A placing frame is fixed on the outer side of the lower end of the shell mechanism; a water inlet is fixed to the left side of the upper end of the shell mechanism, and a water outlet is formed in the right side of the lower end of the shell mechanism. Connecting plates are installed on the inner wall of the outer shell mechanism at equal intervals, and the other ends of the connecting plates are connected with the outer side face of the inner shell mechanism. Wherein a discharging opening is fixed to the bottom end of the shell mechanism, and a feeding frame is installed at the upper end of the shell mechanism. The slag cooler for slag waste heat utilization and recovery is provided with the hollow outer shell mechanism, the hollow inner shell mechanism and the hollow connecting plate, so that the heat exchange area is increased conveniently, the slag waste heat recovery efficiency of slag cooling can be improved, waste heat recovered in the later period can be used for preheating furnace water, steam for preheating the furnace water can be saved, and the energy consumption is reduced. And the waste heat can be well recycled.

Description

technical field [0001] The invention relates to the technical field of waste heat utilization, in particular to a slag cooler for utilization and recovery of slag waste heat. Background technique [0002] In thermal power plants, it is necessary to use boilers and other equipment for coal-fired power generation, and a large amount of slag will be produced after the boiler is burned. At present, the waste heat of high-temperature slag is recovered by a slag cooler on the market, and then the recovered waste heat can be used to preheat the furnace. This can save the steam of preheating the boiler water, improve the thermal efficiency of the boiler, and can also recycle the waste heat to avoid waste heat. However, there are still certain problems when using the slag coolers on the market, such as: [0003] Announcement No. "CN104673400B" disclosed the patent title of "A spiral slag cooler for high temperature and high pressure gasifier", which solves the current slag cooler, su...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a slag cooling machine for utilization and recovery of slag waste heat, to solve the above-mentioned background technology. The ash and slag can only be in contact with a part of the surface of the drum, which makes the heat exchange area not fully utilized and the waste heat recovery is not complete.
