Abstract
The utility model relates to a novel swirl-type water film dust separator, in particular to a novel swirl-type water film dust separator. The dust separator consists of a Venturi (1), a sprayer (2), amain cylinder body (3), a water injection trough (4), a water overflowing hole (5), a cleaning hole (6), a dust separator outlet (7) and two swirl plates (8); the Venturi (1) is arranged at the leftside of the main cylinder body (3) and is connected with the main cylinder body (3); the sprayer (2) is arranged at the upper end of the Venturi (1); the main cylinder body (3) is a round cylinder; the water injection trough (4) is arranged at the middle and upper part of the main cylinder body (3); the water overflowing hole (5) and the cleaning hole (6) are arranged at the right side of the bottom of the main cylinder body (3); furthermore, the water overflowing hole (5) is arranged above the cleaning hole (6); the dust separator outlet (7) is arranged at the top end of the main cylinder body (3); two swirl plates (8) are arranged below the water injection trough (4) respectively; the dust separator has the advantages of corrosion resistance, abrasion resistance and high temperature resistance, low manufacturing cost, convenient installation and light weight, reduces the price of the equipment, and is an ideal matched product for dedusting of a boiler; and the dust separator can playan effect of a desulphurization duster if alkaline water is added in the circulating pool of the dedusting equipment.
Description
Technical field:
The utility model relates to a kind of deduster, especially relates to a kind of spiral-flow type water dust scrubber.
Background technology:
Existing boiler dust remover major part is in the water film dedusting mode, the dust removing effects of this dedusting method is more satisfactory, but also have following some deficiency: the dust removing tube radius of water dust scrubber is excessive, soot dust granule relies on centrifugal force less with the opportunity that moisture film on this wall combines, have the part flue dust to discharge in pipeline, efficiency of dust collection is not high; Water consumption is big, and the flue gas water content of discharge is more, and pipeline and air-introduced machine are had corrosiveness, so can reduce the service life of pipeline and air-introduced machine; Bulky, selection is restricted, and cost is very high, brings financial burden to the user, and promoting the use of of environmental protection equipment caused certain difficulty.
The utility model content:
The purpose of this utility model provides a kind of novel spiral-flow type water dust scrubber, and it adopts natural granite, and through the circular bent plate of machining, overall structure is smooth smooth; Have corrosion-resistant, wear-resistant, resistant to elevated temperatures characteristic; Outside material cast with the high-strength high temperature-resistant acid and alkali-resistance; Cylindrical shell equipment protects steel plate outward, has strengthened the intensity and the service life of equipment greatly; Cost is low, and is easy for installation, in light weight, reduced equipment price, is the desirable boiler dusting auxiliary products of user.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of venturi 1, spray 2, main cylinder 3, water filling mortise 4, spillway hole 5, cleaning eye 6,7, two eddy flow plates 8 of deduster outlet; Venturi 1 is arranged on main cylinder 3 left sides, and be connected with main cylinder 3, spray 2 is arranged on the upper end of venturi 1, main cylinder 3 is a circular cylinder body, water filling mortise 4 is arranged on the middle and upper part of main cylinder 3, and spillway hole 5 and cleaning eye 6 are arranged on the right side, bottom of main cylinder 3, and spillway hole 5 is arranged on the top of cleaning eye 6, deduster outlet 7 is arranged on the top of main cylinder 3, and two eddy flow plates 8 are separately positioned on the below of water filling mortise 4.
Operation principle: dust-contained airflow enters venturi by inlet flue duct, inlet in throat is sprayed into uniformly by water, because flue gas high-speed motion, therefore the water that sprays into is dissolved into tiny water smoke by it, moistening ash material in the flue gas, so the ash material in the flue gas is by moistening, its weight is strengthened and help by centrifugation, in being the wadding stream mode at a high speed, because water droplet and grit difference are bigger, their speed difference is also bigger; The collision cohesion has just taken place in soot particle and water droplet, especially the dust material that particle diameter is tiny can be water-soluble by water smoke, sufficient preparation is carried out in these separation that all are ash is expected, after this enter cylindrical shell, water enters in the tube from deduster top water sink, making whole cylinder inner wall form water membrane flows from top to down, flue gas is entered by the cylindrical shell lower tangential, rotation is risen in cylindrical shell, dusty gas rubs with the moisture film of cylinder inboard wall face under centrifugal action all the time, dusty gas is moistening by moisture film like this, grit flows to the deduster bottom with water, drain from spillway hole, do not have water sealed tank at cylindrical shell bottom back cover and spill from the bottom, have cleaning eye to be convenient to carry out the cleaning of cylindrical shell bottom to prevent flue gas.Waste water is discharged by the bottom spout hole and is entered sedimentation basin after the dedusting, and the precipitation neutralization recycles, and purified gas is drawn by cylindrical shell top conical section, thereby reaches the dedusting purpose.
The utlity model has following beneficial effect: adopt natural granite, through the circular bent plate of machining, overall structure is smooth smooth; Have corrosion-resistant, wear-resistant, resistant to elevated temperatures characteristic; Outside material cast with the high-strength high temperature-resistant acid and alkali-resistance; Cylindrical shell equipment protects steel plate outward, has strengthened the intensity and the service life of equipment greatly; Cost is low, and is easy for installation, in light weight, reduced equipment price, is the desirable boiler dusting auxiliary products of user, as add alkaline water in the circulatory pool of cleaner, can play the effect of desulfurizing dust-collector.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment by the following technical solutions: it is made up of venturi 1, spray 2, main cylinder 3, water filling mortise 4, spillway hole 5, cleaning eye 6,7, two eddy flow plates 8 of deduster outlet; Venturi 1 is arranged on main cylinder 3 left sides, and be connected with main cylinder 3, spray 2 is arranged on the upper end of venturi 1, main cylinder 3 is a circular cylinder body, water filling mortise 4 is arranged on the middle and upper part of main cylinder 3, and spillway hole 5 and cleaning eye 6 are arranged on the right side, bottom of main cylinder 3, and spillway hole 5 is arranged on the top of cleaning eye 6, deduster outlet 7 is arranged on the top of main cylinder 3, and two eddy flow plates 8 are separately positioned on the below of water filling mortise 4.
