Description

Compound Gas-Rotation-Plate Dust Separator

The utility model belongs to the combustion product treatment facility, particularly a kind of compound Gas-Rotation-Plate Dust Separator.

For the protection environment for human survival, prevent atmosphere pollution, the flue gas that burning in the industrial processes is produced must purify.The cyclone type dry method dust of commonly using since efficiency of dust collection low, to the gas cleaning weak effect, eliminated by time limit.Extensively adopt various hydrofilters that industrial smoke is purified at present.These dedusters adopt single purification means usually, though it is simple in structure, but not only dust removing effects is poor, and purified gas is taken water electrode for serious, cause heavy corrosion with blower fan and chimney, although adopt multiple dehydration means, but still have repeatly because of stopping up and resistance increases the situation that the equipment that influences runs well and takes place.

The purpose of this utility model provides a kind of simple in structure, efficiency of dust collection is high, serviceability is good compound Gas-Rotation-Plate Dust Separator.

The utility model is made up of shell, inner core, dedusting eddy flow plate, moisture film structure, sharp mist cover, dehydrated structure and demist eddy flow plate, and shell is for constituting the hollow housing of closed chamber, and its top is provided with the blast pipe that connects with closed chamber; Inner core is the shell-like cylindrical shell that the top is provided with air inlet pipe, and inner core places in the closed chamber of shell, constitutes the dehydration ring cavity between the inwall of its cylindrical shell periphery and shell, and makes its top air inlet pipe pass shell communicating with the external world; The external diameter of dedusting eddy flow plate is corresponding with the inner core cylinder internal diameter, and it places in the cylindrical shell, and is positioned at the joining place of cylindrical shell and air inlet pipe; The moisture film structure has the annular enclosed cover that external diameter is slightly less than the inner core cylinder internal diameter, and its outer wall is all established a plurality of spillway holes and water inlet pipe, and the moisture film structure places in the inner core cylindrical shell and is positioned at the below of dedusting eddy flow plate, and water inlet pipe passes inner core cylindrical shell and shell on it; Swash the mist cover and be bell mouth shape, sharp mist is placed in the closed chamber of shell and is positioned at the inner core below, and makes inner wall surface thereof and inner core cylindrical shell bottom outer rim constitute the sharp mist gap of ring-type; Dehydrated structure is made up of ring baffle plate more than two groups, and annular flap is disposed on inner core cylinder body outer wall and the outer casing inner wall; The external diameter of demist eddy flow plate is corresponding with the blast pipe internal diameter of shell, and places in the blast pipe.

Since the utility model by the shell that is provided with blast pipe, the inner core that is provided with air inlet pipe, dedusting eddy flow plate, moisture film structure, be bell mouth shape and swash the mist cover, be disposed on dehydrated structure and the demist eddy flow plate that the ring baffle plate on cylinder body outer wall and the outer casing inner wall forms more than two groups and form, inner core and sharp mist overlap and place in the shell successively, and outer rim formation ring-type swashs the mist gap bottom the inwall of the sharp mist cover of order and the inner core cylindrical shell; Dedusting eddy flow plate and demist eddy flow plate place respectively in cylindrical shell and the blast pipe.Simple in structure.During use, inject water for dust removal in the enclosure, liquid level is a little less than inner core cylindrical shell bottom surface, and the ring-type that is positioned at inner core and sharp mist cover formation swashs the mist gap location, water inlet pipe through the moisture film structure supplies water to the moisture film structure again, the spillway hole of water on the annular enclosed cover outer wall of moisture film structure flowed out, and form moisture film along the inner core cylinder inboard wall.The air inlet pipe of flue gas through the inner/outer tube top that burning produces enters inner core, through dedusting eddy flow plate it formed to inner rotary flue gas stream, utilizes centrifugal force to isolate major diameter grit in the flue gas and falls into the dedusting water of outer casing underpart, carries out dry dust removal; Rotation flue gas stream contacts with moisture film along the cylinder inboard wall rotation downwards, makes that part grit and sulfur dioxide dissolve in the water in the flue gas, carries out wet dust removal; The rotation flue gas flows to dedusting water liquid level by cylindrical shell and swashs the mist gap location from the ring-type that inner core and sharp mist cover constitutes and go out and evoke water smoke, and the small dust and the sulfur dioxide that rotate in the flue gas dissolve in the water smoke, carry out wet dust removal once more; Purified gas enters and constitutes the dehydration ring cavity between the inwall of cylindrical shell periphery and shell, through dehydrated structure be disposed on more than two groups on cylinder body outer wall and the outer casing inner wall the ring baffle plate baffling upwards, water droplet is separated from Purge gas, dewater; Purge gas after the dehydration rises and enters blast pipe, make it form outside swirling eddy through demist eddy flow plate, utilize centrifugal force to isolate residual droplet and grit in the gas once more, the gas of purification and dehumidification is discharged through air exhauster from the outlet of blast pipe fully, not only efficiency of dust collection height but also serviceability are good, thereby reach the purpose of this utility model.
