Waste heat boiler internally provided with high-temperature ceramic membrane filter assembly

Abstract

The invention discloses a waste heat boiler internally provided with a high-temperature ceramic membrane filter assembly. The boiler comprises a box body, a first return stroke, a second return stroke and a third return stroke are sequentially arranged in the box body, an air inlet communicated with the first return stroke and an air outlet communicated with the third return stroke are formed in the box body, and a high-temperature ceramic membrane filter assembly is arranged in the third return stroke; and a first partition plate and a second partition plate are fixed in the box body, a first notch is formed between the first partition plate and the upper inner wall of the box body, a second notch is formed between the second partition plate and the lower inner wall of the box body, the first return stroke is located between the air inlet and the first notch, the second return stroke is located between the first notch and the second notch, and the third return stroke is located between the second notch and the air outlet. According to the high-temperature ceramic membrane filter assembly, dust is captured on the surface of a ceramic membrane tube, high-temperature flue gas penetrates through the membrane tube, dust in the flue gas is captured, and the content of dust at the air outlet is reduced.

Description

technical field [0001] The invention belongs to the technical field of waste heat boilers, and in particular relates to a waste heat boiler equipped with a high-temperature ceramic membrane filter assembly. Background technique [0002] Waste heat boiler, as the name implies, refers to a boiler that uses waste heat in waste gas, waste or waste liquid in various industrial processes and the heat generated by the combustion of combustible substances to heat water to a certain temperature. [0003] For example, Chinese patent application CN201911189299.9 discloses a waste heat boiler for heat energy recovery of electronic waste combustion flue gas. The partition wall is divided into the first partition wall with a top gap with the top of the furnace and the second partition wall with a bottom gap with the bottom of the furnace. The first partition and the second partition are arranged at intervals, and at least one first partition is arranged in the furnace. One partition wall...
