Description
The invention relates to the invention of a kind of cyclone dust collectors (or cyclonic water film deduster or tornado evaporator) that separating solids from gas (or liquid) particle uses.
Deduster is one of visual plant of using in modern industry production and the environmental protection, and wherein outstanding cyclone dust collectors is applied as at most.Cyclone dust collectors utilize the dedusting of centrifugal inertial force principle, are called centrifugal deduster again.
Deduster commonly used both at home and abroad can be divided into four classes substantially, that is: mechanical dust collector class, wet scrubber class, filtration dust catcher class and electric cleaner class.Wherein the mechanical dust collector class mainly contains three kinds of gravity settling chamber, inertial dust separator and cyclone dust collectors.
In all kinds of deduster of four big classes, mechanical deduster manufacturing installation fee and operational management expense are lower than other three classes deduster, but dust collector efficiency is also corresponding low; With regard to three kinds of mechanical dedusters, the efficiency of dust collection of cyclone dust collectors is for the highest.In a word, cyclone duster structure is simple, movement-less part, easy to maintenance, cheap, and its efficiency of dust collection can reach 90%, thereby is used widely in practice.Yet the technical performance index of cyclone dust collectors can't satisfy actual needs in some occasion.Such as, be used for the smoke abatement and dust control of Industrial Boiler and civil boiler separately, usually can not satisfy the requirement of the discharge standard of regulation.
Domestic and international existing cyclone dust collectors (or wet scrubber or dehydrator) kind is a lot, the inside movement-less part that its major technology characteristics are housings.
Existing cyclone dust collectors generally are made up of air inlet, outer cylinder body, cone, blast pipe (or inner core), ash bucket, ash-discharging device etc., and the part that its blast pipe (or inner core) inserts enclosure interior is fixed.Dusty gas enters in the deduster from the deduster inlet by the power that blower fan provides, and is rotated down earlier and forms outer vortex, and counter-rotating then rotates up the formation inside vortex.Inside vortex itself is little to the centrifugation of dust, so belong to the expendable energy loss, inside and outside in addition vortex contacts, and causes to ooze mixed, collision mutually and disturb, thereby is producing and account for the pure expendable energy loss of loss of total pressure more than 50%.The centrifugal inertial force that solids just obtain in the process that enters the air-flow rotation by it gets separation to a certain degree.These cyclone dust collectors exist that efficiency of dust collection is lower, the pressure loss is big, monotubular deduster barrel diameter is limited and can not satisfy the problems such as requirement of handling big air quantity.
Equal movement-less part in the housing of existing wet scrubber is that obpyriform inner core (fixture), spiral flow deflector, mortar bucket, ash discharge slurry valve are formed by shell body, cross section mainly as horizontal water-film syclonet.This deduster efficiency of dust collection is on the low side, and water phenomenon often appears in the deduster outlet.
The inside of existing tornado evaporator is movement-less part also, and its structure mainly is made up of air inlet, outer cylinder body, eddy flow plate, spill box etc.Dewatering efficiency is 90%, and removable minimum liquid-drop diameter is that resistance is also bigger about 5 μ m.
The objective of the invention is new type cyclone dust collector for a kind of efficiency of dust collection height (satisfying the requirement of national specified discharge standard) being provided, the pressure loss is little, the single cylinder diameter is unrestricted and has low abrasiveness;
Another object of the present invention is for a kind of novel wet scrubber-cylinder-rotating water dust scrubber is provided;
The 3rd purpose of the present invention is for a kind of novel gas-liquid separator-cylinder-rotating centrifugal dehydrator is provided.
