Description
Technical field:
The present invention relates to converter auxiliary equipment technical field, particularly relate to a kind of wet method converter gas purification cleaner and process thereof.
Background technology:
Existing wet method converter gas purification cleaner comprises the two-stage Venturi tube mostly, dehydrator, the water smoke separator, flowmeter, air-introduced machine, triple valve, water processing establishment, gas chamber, equipment such as water seal are formed, the one-level Venturi tube adopts fixedly aditus laryngis formula of manual adjustable aditus laryngis formula or overflow mostly, major function is cooled flue gas and thick dedusting, it is low often to occur thick efficiency of dust collection in the actual production, resistance is big, problems such as water content is big, secondary Venturi tube major function is to remove thin dirt and condensation cooling, form smart cleaner with the front and back dehydrator, its version has experienced adjustable aditus laryngis formula (P-A), movable reprint formula (RD), circumferential weld is heavily cut or polish jade with an emery wheel formula updates such as (RSW), the venturi tube that circumferential weld is heavily cut or polish jade with an emery wheel the formula structure has solved adjustable aditus laryngis formula, the efficiency of dust collection that movable reprint formula Venturi tube exists is low, system is easily stopped up, aditus laryngis is difficult for shortcomings such as adjusting, be a kind of two more advanced civilian cleaners at present, its structure mainly comprises heavily stone roller, heavily cut or polish jade with an emery wheel elevating mechanism, water injector, seal and heavily cut or polish jade with an emery wheel the displacement meter measuring device, inlet tube, contraction section, aditus laryngis, expansion segment, outlet section etc.Heavily Tuo main effect is that control converter mouth elementary errors pressure and the resistance of secondary Venturi tube aditus laryngis are decreased, and then the resistance of Adjustment System distribution at any time under the condition that flue gas constantly changes, thereby reaches the purpose of work best results.Existing wet type converter gas purification dust collection method and technological process thereof are as described below, converter gas enters the thick dedusting of one-level Venturi tube by the gasification cooling stack, enter the elbow separator dehydration after the cooling and enter the secondary Venturi tube again from top, dirt aqueous mixtures after the cohesion enters dehydrator behind secondary Venturi tube lower part outlet, water after the separation enters water processing establishment through water seal and carries out recyclingly, and the gas after the separation is through the water smoke separator, pass through main induced draft fan behind the meter, triple valve enters and diffuses that chimney diffuses or through the rotation water seal, the water seal of U type enters gas chamber and carries out coal-gas recovering.The dust-cleaning principle of Venturi tube is to strengthen flow velocity at aditus laryngis partial fume and washings owing to the flue caliber dwindles suddenly, make the flue gas and the heat transfer water mass transfer that enter aditus laryngis, 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 dehydrator, reach the purpose of gas cleaning dedusting.In the work of secondary Venturi tube, guarantee that flue gas fully contacts with washings, washings are fully atomized also and dust condensing, to improving gas cleaning and dust removing effects is vital, in existing wet method converter gas purification cleaner and technology because the most downstriker process that adopts, being flue gas and washings enters aditus laryngis from the top of secondary Venturi tube, flow out from the below of aditus laryngis, a plurality of nozzles are arranged on the heavily top of stone roller, heavily stone roller is the up-small and down-big aditus laryngis section that is placed on of right circular cone, the problem that this equipment and process exist is to form unnecessary mechanical water when water smoke intersects in a plurality of nozzle water spray processes, under the gravity effect, this mechanical water influences washings during by circumferential weld and fully atomizes at circumferential weld, with dust condensing, and then influence gas cleaning and dust removing effects.
Summary of the invention:
The purpose of this invention is to provide a kind of above-mentioned prior art defective that overcomes, make that circumferential weld mist attitude flow field is more reasonable, gas cleaning and good dedusting effect, the flow of flue gas direction is the converter gas purification cleaner and the process thereof of upstriker.
