Description

A kind of eddy flow dehydrator of novelty

Technical field

This practical eddy flow dehydrator that relates to a kind of novelty belongs to the metallurgical environmental protection equipment technical field.

Technical background

The oxygen coverter gas cleaning, exhausted most wet type flue gas desulphurization system flow that adopts, the smart dehydration equipment that purifies of afterbody flue gas is divided into four kinds substantially, 90 bend pipe dehydrators, folded sheet dehydrator, the wet dehydrator, wire mesh dehydrator of revolving.Preceding two kinds of sides imitate Baosteel, introduce Japan's 300 tons of converters digestion environmental protection equipment, and back two kinds be shanghai institute of metallurgy designing research respectively at 1966 and the non-standard equipment that designed in 1972.Wire mesh dehydrator is to go up steel one factory 30 tons of converter gas purification afterbody dehydrators in 1966, because of containing a certain amount of Ca (CH) 2 in the flue dust, with contain CO2 gas by the time, form the CaCo3 lump, after invalid, be forced to cancellation with high pressure water washing.The wet dehydrator that revolves is to go up 25 tons of converter gas purifications of steel three factories in 1972 to spray dehydration equipment in the full wet method low pressure process of multiple shelves, the multiple shelves of original name dehydrator again.Above-mentioned four kinds of dehydration equipments, ubiquitous problem, dewatering efficiency is not high, impossible single use, easily stifled, drag losses is big, even the water flushing also is difficult to wash out the CaCo3 lump of forming in the flue dust, scene regularly workman enters flushing of dehydrator inner high voltage water and artificial deashing.

For improving dehydrating effect, several dehydrators are connected in series use, 300 tons of converter days of Baosteel the design " R-O " reprint Venturi tube, afterbody dehydration equipment are that 90 degree bend pipe dehydrators and two kinds of series connection back of water fender water smoke separator (promptly folding dehydrator) are provided with flowmeter in the literary composition (reality also plays dedusting and dehydration).The last dehydration of the gas cleaning in domestic most converter shed is general adopts three dehydrators to be connected in series use; promptly 90 spend bend pipe dehydrator folded sheet dehydrators; wet dehydrator or the silk screen hydrophone of revolving; venturi meter is not established in the back; it is big not only to take plant area; drag losses is bigger; also have a cover water flushing to connect trivial control system, water consumption increases, and investment cost is many; and Maintenance and Repair want workload to increase; must regularly enter and use high pressure water washing and artificial deashing in the dehydrator, work ring mirror is abominable, and labour intensity is big; simultaneously because dehydrating effect; not ideal, the dust of the water droplet folder that flue gas is medium and small is easy to adhere to tube wall and draught fan impeller; cause the uneven vibrations of blade; often blower fan is by forced-stopping machine, and maintenance deashing and dynamic balance check influence the steel-making ordinary production; some converter shed of China adopts standby fan to take turns deashing for this reason, but must establish liaison tube and valve between blower fan.Because the discontinuity of converter, unavoidably amass sometimes between liaison tube coal gas and air are arranged, although do not blast accident as yet, but the potential safety hazard that it stays can not be underestimated, gratuitously provided Ma Gang company three steel mills 50 tons of converters in 1999 with Japan, a complete set of flue gases purification equipment is example, after the smart purification of downstriker circumferential weld Venturi tube flue gas, be provided with 90 bend pipe dehydrators, the folded sheet dehydrator and 90 bend pipes that fall.Dehydrating effect is bad, and the sticking ash of impeller of blower is serious, general draught fan impeller deashing 10-15 days, and indivedual 20 days are once, and 300 tons of converters of Baosteel have one day shutdown maintenance system weekly, and blower fan is introduced, and impeller has four nozzle rinse devices.

Summary of the invention

This practical purpose is to provide a kind of eddy flow dehydrator, and this eddy flow dehydrator is that a kind of to take plant area few, must the water flushing, and reduced investment, equipment making is simple, the dehydration equipment that Maintenance and Repair are few.

For reaching above-mentioned purpose, the technical solution of the utility model is: comprise that simple and reasonable Aspect Ratio has the blast pipe of gas-liquid Gravity Separation, guiding rotational flow separation plate, smart separate blade of mold pressing and water fender four major parts are placed in the vertical cylindrical shell, and it is few to take the factory building area, non-flushing washing, certainly also just do not have the water flushing to connect trivial control system, must the workman not enter Maintenance and Repair or seldom Maintenance and Repair in the dehydrator, dehydrating effect is good.

Effect of the present utility model: it can divide in the separable flue gas≤water droplet under 100 particulates, according to the actual use of shutout rear fan impeller deashing being arranged about 60 days blanking times, surpass more than 80 days at most, make simple reduced investment, be a kind of desirable environmental protection dehydration equipment.

Below in conjunction with accompanying drawing with implement to the utility model detailed explanation of making comparisons.
