First order Venturi tube gas cleaning wash mill in the above-mentioned converter gas purification system generally is made up of inducer, contraction section, aditus laryngis section, expansion segment, wherein inducer adopts the mode of insulated water jacket and the combination of overflow tank, is provided with one deck bowl-type nozzle in the aditus laryngis section.In the converter gas washing, first order Venturi tube gas cleaning wash mill plays a part cooling and dedusting, in aditus laryngis section part, first order Venturi tube causes bigger relative velocity with certain gas speed and water speed, make the high-temperature gas and the heat transfer water mass transfer that enter, simultaneously, clashed into cohesion by grit in the water droplet group of aditus laryngis high-speed gas atomization and the air-flow, become the dirt aqueous mixtures, make gas-water separation through the gravity dehydration device then.The characteristics of first order Venturi tube are: efficient is higher, and water is less, but resistance is bigger.Because after flue gas flows to the contraction section of first order Venturi tube, the flue gas static pressure progressively descends.In the difference of aditus laryngis section part with larynx speed, minimum is in various degree reduced in flue gas static pressure to aditus laryngis section outlet, flue gas enters in the expansion segment, the flue gas static pressure progressively is restored again, physical dimension and structure according to different Venturi tubes, expanding the expansion segment exit, the big activation of flue gas static pressure returns to about 60-85%.
From the course of work of above-mentioned first order Venturi tube is described as can be known, the resistance of first order Venturi tube (pressure loss) means that gas enters in the pipe and friction such as tube wall, and aqueous vapor kinetic energy transmits the gas pressure that (water droplet quicken absorbed energy and its energy of emitting) etc. lost in anemostat in trunnion.The resistance of first order Venturi tube comprises its dried resistance and wet resistance, if be provided with the overflow water seal at first order venturi inlet place, also has spillage drag.The size decision of dried resistance and larynx speed, geometry and the machining accuracy of aditus laryngis section; The size of wet resistance also determines and steam ratio, water discharge pattern etc., and these resistance sums are the drag overall by first order Venturi tube.
The calculating resistance of converter gas purification system first order Venturi tube gas cleaning wash mill is generally all at 300mmH
2About O.
The utility model content
The purpose of this utility model is to provide a kind of saturated spray column of gas cleaning that substitutes the effect of first order Venturi tube gas cleaning wash mill in the converter gas purification system that is applicable to, this saturated spray column circulation area is big, and resistance is little, purification efficiency is high.
For achieving the above object, the saturated spray column of converter gas purification of the present utility model comprises gas approach section, expansion segment and contraction section, and wherein inducer is made up of insulated water jacket and overflow tank, and its structural feature is: expansion segment is positioned at the inducer below; Be provided with the upper, middle and lower cylindrical shell in the expansion segment lower end; Contraction section is positioned at the lower shell lower end; Between inducer and the expansion segment, between expansion segment and the upper shell, adopt between each cylindrical shell and between lower shell and the contraction section and be fastened and connected; Be provided with osculum in the contraction section lower end, be provided with the exhanst gas outlet pipeline in the middle cylinder body side; 4 layers of spray nozzle also are set in saturated spray Tata at least.
The utility model structure compared with prior art its advantageous effect is as follows:
Because the saturated spray column of the utility model adopts the tube structure form, circulation area is big, and directly cooling down high-temperature gas captures the coarse grain dust; Owing in tower, be provided with at least 4 layers of spray nozzle, form the water smoke film by nozzle like this, the cooling of the gas that reaches a high temperature and dedusting again.The pressure loss of this dedusting is extremely low, and the plan pressure loss is at 50mmH
2Below the O.So advantage simple and reasonable, that resistance is little, the turbid circulating water consumption is little and purification efficiency is high that the saturated spray column of the utility model structure has.
