Description

The wet vibration dust remover with fibre-gates

The utility model relates to labour protection, environmental protecting device, particularly a kind of wet vibration dust remover with fibre-gates.

Employed cleaner can be divided in two kinds of formula, wet types in the dustproof process in down-hole, there are a lot of problems in dry-type dedusting equipment on safety, management and material are handled, therefore underground work multiselect wet dust removal more, low as a kind of cost, the method of high-effective dust-removing, wet dust removal is widely used in all trades and professions.Existing wet scrubber has (seeing Table 1～8 in 1) such as board plug type deduster, cyclon dust collector, metal gate formula dedusters, and these deduster ubiquity water consumption are big, the processing air quantity is less than normal, resistance big and efficiency of dust collection problem still on the low side.

The purpose of this utility model promptly is at above-mentioned existing in prior technology deficiency, comprise the problem of aspects such as water consumption is big, the processing air quantity is less than normal, a kind of water consumption is little, the processing wet vibration dust remover with fibre-gates that air quantity is big, resistance is low, efficiency of dust collection is high and provide.

The purpose of this utility model is achieved through the following technical solutions:

A kind of wet vibration dust remover with fibre-gates, mainly form by blower fan (1), casing (2) and fiber grid (7), casing (2) is circular with the end that blower fan (1) joins, its center is provided with awl cylindricality air deflector (8), the other end of casing (2) is square, and be connected with square diffuser (6), fiber grid (7) are contained in the port of export of square diffuser (6); Casing (2) is equipped with water pipe (3), compressed air hose (4), and ultrasonic atomizatio nozzle (5) is housed.Fiber grid (7) mainly are made up of fixed mount (701) and filament (703), wherein, fixed mount (701) is the framework of a square hollow, and its cross section is rectangular, go up fixed number layer filament (703) at fixed mount (701), between every layer of filament (703), all be lined with pad (702); Also has anti-stick fiber parallel (704) in the centre of fiber grid (7).The pack completeness of fiber grid (7) is 2～12%, and its optimum value is 4～6%, and the silk footpath of filament (703) is 0.04～0.2mm, its optimum value is 0.08～0.15mm, the silk spacing is 0.1～0.3mm, and its optimum value is 0.1～0.22mm, and the filament number of plies is 6～14 layers.

The utlity model has following advantage and effect:

1. on structure, first the ultrasonic atomizatio nozzle is applied to deduster, has improved the cohesion of dust, and reduced water consumption.Water spray, the drop size that spraying system sprayed have very significant effects to dust collection effect, when water droplet is excessive (as spraying nozzle, spraynozzle, the water droplet＞60 μ m of sprayer ejection) athletic meeting of big water droplet forms the air blast that can sweep away grit, stop grit and droplets impact its, be unfavorable for gathering dust, and the utility model selects for use the ultrasonic atomizatio nozzle to produce the cohesion that tiny droplet (average diameter is 7.3 μ m) can improve dust, helps gathering dust.

2. filter course adopts dacron thread fiber grid, have corrosion-resistant, acid and alkali-resistance, do not absorb water and characteristics that cost of manufacture is low, and bar structure compares with network structure, has the low advantage of resistance, can produce vibration under distinguished and admirable effect, helps improving capturing fine dust.Can be when in wet scrubber, using from deashing, maintenance is little.

With the deduster of other type (as in the table 1 listed preceding 8) compare, wet vibration dust remover with fibre-gates of the present utility model (table 1 listed last) has and handles obvious advantage and the effect that air quantity is big, efficiency of dust collection is high, resistance is low, water consumption is little.

4. scope of application broadness can not only be used for the mine dust removing down-hole, and can be widely used in industries such as building materials, metallurgy, cement, casting.
