CN2754707Y - Composite wetting dust collector - Google Patents

Abstract

The utility model relates to a composite wetting dust collector capable of utilizing a wetting method to collect dust. The utility model organically combines water washing dust removal and foam dust removal together and adopts a primary water-adding and secondary dust-removing purifying technique and a pneumatic control technique to play a comprehensive effect of smoke abatement, dust removal, water saving and coal economization. The composite wetting dust collector is especially suitable for medium and small coal burning boilers for living and industries. The composite wetting dust collector is characterized in that a pumping machine, a smoke and gas inlet, a smoke flow guiding cover, a water sprinkling disc, a water inlet, a purified gas outlet and a dust discharging port are orderly connected, wherein the pumping machine is formed by the connection of a speed regulating motor and a machine body.

Description

Combined type wet dedusting equipment

One, technical field:

The utility model relates to a kind of combined type wet dedusting equipment, belongs to the environmental protection field.

Two, background technology:

The harm that the dirty seven pair of health of atmosphere causes, to the influence of agricultural, to the harm of livestock, the corrosion of various article is more and more caused people's great attention, and cigarette is cause atmosphere dirt seven the most obvious, maximum enemy.Fuel combustion is the important source that cigarette generates.The control of cigarette is mainly adopted method synthesis such as smoke elimination and dedusting administer, dedusting has become the important measures of environmental protection.Dedusting technology mainly adopts dry method dust, wet dedusting and electrostatic precipitation etc.When dust granule is very little, utilize dry method dust to be difficult to obtain high efficient sometimes; The electrostatic dust collection equipment expense is big, and wet dedusting is adopted comparatively general.At present, wet dedusting mainly is foam dust-removing and cleaning dust (mechanical scrubber and Venturi scrubber), more than two kinds of dedusting technologies and equipment all have certain merits and demerits, merits and demerits separately at efficiency of dust collection, equipment structure, environment for use, running expense and operating effect etc., unsatisfactory in particular for the effect of middle and small burn coal boiler (as life use stove etc.) smoke abatement and dust control.

Three, summary of the invention:

1, the technical problem that mainly solves of the utility model: in order to improve the smoke medicining dust-removing effect of fuel boiler, particularly live with the needs of various small scall coal-fired boiler smoke abatements and dust controls, the utility model is intended to design a kind of simple and convenient, economical and practical combined type wet dedusting equipment.The technical problems to be solved in the utility model mainly contains three aspects: the one, utilize the principle of wet dedusting, and water washing dedust and foam dust-removing are organically combined, adopted the purification techniques that once adds water, final dusting.The 2nd, dust discharge behind the purifying and dedusting and treatment technology.The 3rd, the operating pressure control technology in deduster and the coal-burning boiler.

The technical scheme that adopts when 2, the utility model solves its technical problem: device is pumped equipment between boiler and deduster, and for protecting certain blast, Forced draught blower has adopted the control of adjustable speed variable-frequency motor.Deduster mainly by dust inlet pipe, flue dust kuppe, sieve plate, spread water pond, visor, water level meter, dust emission mouth, clean gas outlet etc.Two on sieve plate divides up and down and installs, and the flue dust kuppe evenly is welded on the upper end of dust import by four rods.Spread the tapered shape of water pond, water inlet place (being the top of bullet) is equipped with a porous plate, and moisture is sprinkling upon on the sieve plate.

3, practical function of the present utility model: since the utility model project organization and assembling mode, the resultant effect of reached smoke elimination, dedusting, economizing on water, economizing on coal, and the utility model combined type wet dedusting equipment has been compared following advantage with other same category of device:

1., simple in structure, easy to make, flexible operation, volume be little, in light weight, applicable to industry and life fuel medium small boiler.

2., because water plays the secondary action of foam dust-removing and cleaning dust, can economize on water 50%.After discharge water focuses on, also can be recycled, water use efficiency can reach more than 95%.

3., the efficiency of dust collection height, can reach more than 98%, reach waste gas emission standard.

4., the coal dust ash mixes new coal and can do second-time burning, plays the effect of economizing on coal equally, and is energy-conservation more than 25%.

5., can control the fire position naturally.

Four, description of drawings:

Fig. 1 is a package assembly schematic diagram of the present utility model.

Fig. 2 is the perpendicular figure that cuts open of the present utility model.

Fig. 3 is the cross-sectional figure at the utility model Fig. 2-AA place.

Below in conjunction with accompanying drawing the utility model is further described:

Among Fig. 3, the 1st, clean gas outlet, the 2nd, spread water pond (having a porous plate), the 3rd, water inlet pipe, the 4th, sieve plate (can duroplasts, pottery or through two layers up and down of the materials such as steel plate of preservative treatment), the 5th, deduster staving.The 6th, the flue dust kuppe, the 7th, a rod, the 8th, the water level meter, the 9th, the dust import, the 10th, pump machine, the 11st, variable-speed motor, the 12nd, coal-burning boiler, the 13rd, visor, the 14th, dust emission mouth, the 15th, valve.

Five, the specific embodiment:

Among Fig. 1, coal-burning boiler (12), axle send machine (10), flue dust air inlet (9) to link to each other with deduster staving (5) below center position.In Fig. 2, dust import (9), prop up rod (7), flue dust kuppe (6) links to each other, spreading the top that water pond (2) is arranged in deduster staving (5) links to each other with deduster staving (5) by water inlet pipe (3), clarifier outlet (1), sieve plate (4), visor (13), dedusting floss hole (14) links to each other with deduster staving (5), clarifier outlet (1) is positioned at the top, center of deduster staving (5), sieve plate (4) is positioned at the body meat of deduster staving (5), be positioned at the centre of spreading water pond (2) and flue dust kuppe (6), visor (13) is positioned on the side staving of deduster staving (5), and dust emission mouth (14) is positioned at below one side of deduster staving (5).

Claims (2)

1, a kind of combined type wet dedusting equipment, be positioned at the top of coal-burning boiler, it is characterized in that: pump machine, the dust import is connected with the deduster staving, flue dust kuppe, a rod are connected with the dust import, spread water pond, water inlet pipe is connected with the staving of cleaner, sieve plate is connected with the staving of cleaner, be positioned at the centre of removing water pond and flue dust kuppe, clarifier outlet be positioned at staving directly over, the soot emissions mouth is positioned at below one side of deduster staving, and visor, water level score are not connected the both sides of deduster staving.
