Problems solved by technology

[0006] This cyclone dust collector with a water jacket has the following disadvantages: the water jacket is arranged outside the tower, the heat-absorbing area of ​​the phenol water is only the part in contact with the tower body, and the phenol water located on the periphery of the water jacket cannot directly obtain the dust. heat, resulting in a low conversion rate of waste heat in the tower

Abstract

The invention discloses a waste heat recycle cyclone dust collector which comprises an inner cylinder and an outer cylinder, wherein the outer cylinder is externally provided with a water jacket; a spiral flow guide body is arranged on an inner wall of the outer cylinder; the flow guide body is hollow; a flow guide groove is formed in the middle of the flow guide body; the upper end of the flow guide groove extends to the outside of the outer cylinder; a water inlet is formed at the upper end of the flow guide groove; the lower end of the flow guide groove is communicated with the bottom of the water jacket; and an air outlet is formed at the upper part of the water jacket. The waste heat recycle cyclone dust collector can increase heat absorption area of phenol water and a waste heat conversion rate of smoke.

Description

technical field [0001] The invention relates to a cyclone dust collector, in particular to a cyclone dust collector for waste heat recovery and utilization. Background technique [0002] The phenolic sewage of the gas station is composed of harmful substances such as phenols, cyanides, tars, suspended solids, sulfides, ammonia nitrogen, and chlorides. Among them, the main phenols are monohydric phenols, with the highest content of phenol, followed by m-p-cresol, which comes from the indirect cooler washing water and phenolic condensate in the process of cooling and purifying gas, and the formation of phenolic condensate The amount depends on the gasification coal quality and the gasification process used. Taking the gasification of Datong bituminous coal in the two-stage furnace gas station as an example, the gas in the upper stage is finally cooled by the indirect cooler, and the amount of condensed water produced is about 100kg / t coal, and the phenol content of the cond...
