Abstract
A horizontal self-exciting water-bath water-membrane deduster for mine is composed of water charging part, water discharging part, dewatering part and corresponding axial-flow or centrifugal blower, and features small size, light weight, simple structure, easy movement, low water consumption, low resistance and high dedusting efficiency.
Description
Because the particularity of mine underground work, the mining work space of planes is little, equipment moves frequently, therefore, requires employed deduster to have that volume is little, in light weight, movable maintenance makes things convenient for, and efficiency of dust collection height (especially to respirable dust).So just limit the employed high-efficiency dust remover of ground industrial and mining enterprises and can not directly apply to the down-hole, need develop according to actual operating conditions.At present, the employed deduster type of China's mining excavation working face is varied, deduster from external introduction is arranged, the deduster that improves and develop is voluntarily arranged, but, these dedusters are in all not fine use of China, and its basic reason is external deduster technical parameter incompatibility that introduce or improved China mine production specifications; Though Yan Zhi deduster has advantages such as volume is little, in light weight voluntarily, easily stop up and damage, and not high to the efficiency of dust collection of respirable dust.Therefore analyzed the design feature of domestic and international various dedusters in person, through a large amount of laboratory model research, developed that a kind of volume is little, in light weight, simple in structure, conveniently moving, horizontal self-excitation bathing water film deduster for mine efficiently.
The deduster structure as shown in drawings, it mainly contains entry section I, water exit end II and dewatering period III three parts and forms; Its structure mainly contains compositions such as air inlet 1, last guide vane 2, deduster shell 3, V-type dehydrator 4, W type dehydrator 5, air outlet 6, circular flange 7, water tank 8, pulp-expelling valve 9, following flow deflector 10, dipperstick 12, water injection hole 13 and rectangular flange 14.
Its dust removal process is that dusty gas enters the guide vane impact water surface that deduster is turned downward by air inlet, bigger grit is because effect of inertia falls into water tank, and less grit, fully collides and the sedimentation that is hunted down with a large amount of water droplets that evoke during at a relatively high speed by the bending channel between guide vane up and down with air-flow.The moisture air-flow of dust-laden at the deduster inwall with form certain thickness moisture film on the guide vane up and down, captures grit and descends again under action of centrifugal force.After removing water droplet water smoke in the air-flow by dehydrator again, be discharged in the tunnel through supporting blower fan; Its dust removal mechanism mainly be in the air-flow grit and liquid level and this generation inertial collision of atomized drop, hold back, effect such as diffusion.In a word, this deduster has three kinds of dedusting functions such as moisture film of water-bath, water droplet, centrifugal force generation, thereby can obtain higher efficiency of dust collection, and efficiency of dust collection is more than 98% after measured.In addition, captured the dust fall in the water tank, deposit to water tank bottom or constantly stir, after concentration reaches certain value in the water tank, regularly discharge by pulp-expelling valve with gas shock by water droplet, and flush box, new water replenished by feed pipe.
Claims (2)
- This deduster is in investigation and analyzes existing deduster and (easily stop up damage, unstable properties as filtration dust catcher, and other wet scrubber water consumption is big, efficient is low etc.) on the in use in-problem basis, through a large amount of experimental studies, and efficient, practical, the novel deduster developed.Characteristics such as it is simple and light, appearance and size is little, be easy to carrying, resistance is low, noise is low, water consumption is few, equipment cost is low.In addition, can be according to the requirement of actual dedusting air quantity, the deduster of design different size is to reach the purpose of high-effective dust-removing.This deduster can be used for the dedusting at place, down-hole and ground various concentrated dirt source, the dust that the spraying machine each several part produces when also can be used for controlling tunnel (tunnel) bolt-spary supports.1. small-sized deduster major technique is characterized as: the processing air quantity is 60m 3/ min, working resistance 1100Pa, total efficiency of dust collection is more than 98%, the respirable dust efficiency of dust collection recycles water more than 90%, regularly puts, water filling, join corresponding explosion-proof axial flow or centrifugal fan, appearance and size length * wide * high (mm)=1500 * 360 * 800.
- 2. the scope of asking for protection is: the supporting mode of the version of deduster (comprising entry, water outlet and dewatering type) and each parts of deduster.
