Spray tower with gas flow equalizing device

Abstract

The invention provides a spray tower with a gas flow equalizing device. The spray tower with the gas flow equalizing device comprises a spray tower, a gas inlet is formed in the lower part of the spray tower; a gas outlet is formed in the top of the spray tower; the spray tower further comprises a circular flow guide cylinder and a conical flow guide cylinder located above the circular flow guidecylinder. An annular flow equalizing area is formed between the circular flow guide cylinder and the tower wall of the spray tower, the gas inlet is formed in the tower wall of the spray tower corresponding to the annular flow equalizing area, the conical guide cylinder is located above the circular guide cylinder, the diameter of the upper end of the conical guide cylinder is larger than that ofthe lower end of the conical guide cylinder, and a gap is formed between the lower end of the conical guide cylinder and the circular guide cylinder. According to the spray tower, gas enters the towerbody of the spray tower, and can only enter the spray area from the gap under the flow equalization effect of the circular guide cylinder. The circular guide cylinder and the conical guide cylinder have buffering and flow equalizing effects so that the gas is more uniform in the spray area of the tower body, the influence of incoming flow change on flow equalization is small, and the flow equalization problem of the gas in the horizontal direction is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of coal gas dedusting, and in particular relates to a spray tower with a gas equalizing device. Background technique [0002] Due to the advantages of full-dry bag dust removal in terms of energy saving, environmental protection, and good dust removal efficiency, more and more blast furnace gas purification processes have begun to adopt this dust removal method. However, the problems brought about by this process are also quite obvious and common: when the temperature drops, the acidic components in the clean gas after dust removal will be separated out, which will seriously corrode or even penetrate the gas pipe network and equipment in a short period of time, resulting in gas leakage And other safety accidents seriously affect the normal operation of blast furnace production. [0003] Spray tower deacidification process is the most widely used deacidification method in engineering at present, but due to t...

However, this arrangement of flow equalizers is closely related to the incoming flow, and can only guarantee a better flow equalization effect at a specific flow rate.
