Abstract

The utility model relates to a dust remover. A flow guide plate is arranged on the inlet section of the dust remover. The inner space of a shell is divided into a high-speed fume flow zone in an upper part and a high negative pressure zone in a lower part. The shaft line of a first level horizontal type louver rotating wheel is perpendicular to the centerline of the shell. The upper part of the louver rotating wheel is provided with a magnetized ionic liquid jetting pipe; an ash bin is arranged at the lower part of the louver rotating wheel; a louver type water stop plate is arranged on the back part of the louver rotating wheel. The shaft line of a secondary wind blade rotating wheel and the centerline of the shell are coaxial. A bearing seat is provided with a cooling water pipe and a water jetting nozzle, and a ring-shaped ash bin is arranged on the periphery of the bearing seat. The ionic liquid is used as the separating agent. The centrifugal force is used for separating dispersed particles. The utility model has the advantages of small resistance, no clogging and strong adsorption force and resulting force, can remove the smoke, the dust, the greasy dirt, the fibrous dust and the mineral powder, can decarbolize, and is used for various dust removals.

Description

Duster

The utility model belong to adopt liquid as release agent, utilize centrifugal force, from gas, air, separate dispersed granules, particularly a kind of employing is magnetized ionic liquid as release agent, utilizes the rotating cylinder of rotation to produce centrifugal force, from the device of coal-burning boiler smoke evacuation or other dust places separation flue dust.

At present, the dust arrester of boiler exhaust gas is a lot.Have and adopt liquid as release agent, as venturi wet dust collector commonly used, adopt the spray water bath dust-removing, concrete structure is as establishing the Venturi tube spraying and dedusting in the deduster housing, again through eddy flow plate or sieve plate, trickle on sieve plate, form the fluidizing fluid-bed of water, flue gas passes through sieve plate, through with the coal gas and the pernicious gas of bonding dust of water and hydrate reaction, be expected to get rid of, flue gas is purified, venturi spray water-bath dust arrester structure is simpler, but efficiency of dust collection does not often reach national requirements for environmental protection; Have and utilize centrifugal force, rely on wheel blade, the rotating cylinder of rotation to produce centrifugal force, when flue dust passed through rotating cylinder, dust was separated, as the aerofoil profile Spiralism type, fin rotates in water, produce negative pressuren zone on its surface, and flue dust is pressed in the water, flue gas reaches purification, the deficiency that exists is that airfoil fan rotates in water and needs power to realize, the structure more complicated.

The purpose of this utility model is that the employing rotary blade produces centrifugal force and the magnetization ionic liquid is made release agent, and flue gas is carried out two stage treatment, makes the cleanliness factor that reaches the lingemann blackness one-level, satisfies national requirements for environmental protection.

Deduster of the present utility model is made up of housing, rotating cylinder, jet pipe, water fender, it is characterized in that, is provided with deflector at the entrance of deduster housing, and space in the housing is divided into top high speed cigarette flow area, bottom high negative pressure district; The one-level rotating cylinder is the blinds runner, the blinds runner is horizontal, axis is vertical with the housing center line, the vanes fixed of blinds runner is on runner outer rim wheel rim, blinds runner bearings at both ends is fixed on the outer angle bar bearing of housing, and bearing and housing connecting portion are provided with sealing device, and blinds runner top is provided with magnetization ionic liquid jet pipe, the bottom is provided with grey storehouse, and the discharge pipe lower end is provided with water seal under the grey storehouse; Vertical water fender is established at blinds runner rear portion, and water fender is a louvered; At vertical water fender rear, the secondary rotating cylinder is set, the secondary rotating cylinder is the fan blade runner, the blade of fan blade runner is the oblique uniform wheel hub outer fringe surface that is arranged on of 45 degree, and the fan blade runner is coaxial with the center line of deduster housing, and fan blade runner bearings at both ends is by the inner walls bracket supports of feeling relieved, bearing block is provided with cooling water pipe and water spout, the bearing cap center is provided with tank filler sleeve, the grey storehouse of fan blade runner outer periphery annular, and the discharge pipe lower end is provided with water seal under the grey storehouse.

Using method of the present utility model is, deduster is installed between smoke discharging pipe and the air-introduced machine, is horizontal and the flue equal diameter, at flow velocity 17-18 meter per second, works under temperature 140-170 ℃ the flue gas stream mode.When flue gas flows to into the deduster entrance, diversed plate is divided into the high speed cigarette flow area and the bottom high negative pressure district on top.Flue gas promotes the blinds of blinds runner through high speed cigarette flow area, make blinds runner high speed rotating, accept the spray of magnetization ionic liquid simultaneously, the liquid medium that is sprayed on the blade is broken up, the inner chamber that is covered with housing, become the vaporific district that the liquid pearl is differed in size, high speed flue gas stream in the flue is through behind the fog-zone, flue dust in the flue gas stream and sulfur dioxide are by liquid pearl absorption affinity, form dirt liquid mixed bead, because volume, weight reduces flow velocity greatly, and in the negative pressuren zone attached to the louvre blade back side, and the flue gas that purified continues to push ahead at a high speed, promote blinds runner high speed rotating, under centrifugal action, louvre blade gets rid of grey storehouse into the high negative pressure district with the mixed liquor pearl of vacuum side of blade, another part liquid pearl is carried forward by high velocity air and flows and mixed liquor pearl that the blinds runner throws away is run on the water fender at blinds runner rear portion, forms big pearl liquid sinking ash charge storehouse; Still the less liquid integument high velocity air of surplus a part of volume is brought on the fan blade runner at rear portion, the fan blade runner relies on high velocity air to promote to rotate, the liquid that the two sides of blade is sprayed behind the cooling bearing continuously covers, the back side of fan blade runner bucket is negative pressuren zone, under centrifugal action, low speed liquid pearl bumps at the negative pressuren zone of vacuum side of blade and adheres to, and is dumped into secondary ash storehouse, what enter air-introduced machine at last is air-flow after purifying, reaches high cleaning.

The utility model has the advantages that resistance is little, not blockage phenomenon; Adopt ionic liquid, be alkalescence, have strong actively and to the affinity of sulfur dioxide, under 140 ℃ operating mode, absorption affinity and affinity are very strong,, dedusting, desulfurized effect are good; What adopt is the means that efficient absorption and centrifugal force filter, be able to the fiber dust to the cotton mill, the mineral dust of down-hole, mine and the dust removal process of gas, efficiency of dust collection reaches 99%, lingemann blackness is an one-level, can be installed in the blast pipe of automobile, internal combustion engine and use, to remove greasy dirt, black smoke, noise reduction.Be applicable to the dedusting in flue and other dust places.
