Improved multi-pipe drum-type slag cooler

Abstract

The invention discloses an improved multi-pipe drum-type slag cooler, and belongs to the technical field of slag coolers. The slag cooler comprises a slag inlet pipe assembly and a drum. A slag inlet bent pipe and a slag outlet bent pipe are respectively arranged at the slag inlet end and the slag outlet end of the slag inlet pipe assembly; the slag outlet end of the slag inlet pipe assembly obliquely extends into the drum; a slag conveying device and a slag cooling device matched with the slag conveying device to work are arranged in the drum; an included angle of 90 degrees is formed between a pipe opening of the slag outlet bent pipe and a slag inlet of the slag cooling device; and the included angle between the center line of the slag inlet pipe assembly and the horizontal line is 50 degrees, the drum is obliquely arranged on the horizontal plane, and the included angle between the drum and the horizontal plane is 5 degrees. According to the scheme, the angle of the pipeline of the slag inlet pipe assembly is adjusted to be 45 degrees, the slag cooler is integrally installed to be inclined by 5 degrees, the angle of a slag falling pipe can be 50 degrees, and the slag blocking problem is solved.

Description

technical field [0001] The invention relates to the technical field of slag cooling machines, in particular to an improved multi-tube drum type slag cooling machine. Background technique [0002] The slag cooler is a circulating fluidized bed boiler high temperature slag cooling and conveying equipment. The high-temperature slag enters the slag cooler through the slag inlet of the slag cooler and then disperses into the cooling pipe inside the slag cooler. The purpose of cooling is achieved through heat exchange between the pipe wall and the cooling water, and the purpose of transportation is realized through the rotation of the drum. (The high-temperature slag is about 800-1000 degrees, and it is below 100 degrees after cooling). [0003] At present, there are at least the following problems in the slag cooling process of the slag cooler: first, when the slag pipe is spraying slag, there is a problem that hot slag directly enters the cooling pipe; second, the connection be...

Problems solved by technology

[0003] At present, there are at least the following problems in the slag cooling process of the slag cooler: first, when the slag pipe is spraying slag, there is a problem that hot slag directly enters the cooling pipe; second, the connection between the drum and the slag pipe must be There is a gap (dynamic and static joint), in order to make the slag fully enter each cooling pipe, the slag must reach a certain height, and the slag will leak when the high-temperature slag accumulation height reaches this height; Unreasonable, resulting in easy formation of slag blockage at the mouth of the slag inlet. Once the slag blockage is unblocked, a large amount of high-temperature slag will pour in (or the furnace will be blown down by the wind) resulting in slag spraying
