Description

A kind of dust-extraction unit
Technical field
Being applied to industry, civilian deduster the present invention relates to a kind of, belongs to field of environment protection.
Background technology
All the time, bag filter and electric precipitator are widely used in industry and are led with civilian waste gas dedusting purification Domain, proportion are up to 95% or more.Again because the average dust removal efficiency of bag filter is higher than electric precipitator, occur in item In the case that part is permitted, bag filter gradually replaces the trend of electric precipitator.But every cube in prior art dust collector box body The filter bag area that rice can be used for filtering is 9-10m2/m3, the corresponding dust pelletizing system investment of every square metre of filter bag is caused to be up to 450- It 600 yuan, is limited, invests in order to control, it is higher that the prior art generally sets filtration velocity, is 0.8-1m/min, that brings asks Topic is system operation high energy consumption, and concentration of emission is difficult to decrease.
The purpose that the present invention invents just is to provide a kind of scheme that can greatly improve bag filter babinet utilization ratio, Compared with traditional technology, in the case where box volume is constant, filter cloth bag area is significantly increased.Air quantity is handled in the unit interval Under the premise of constant, so that filtration velocity is dropped to 0.25-0.35m/min, and then reduce operating cost, improve efficiency of dust collection.
Technical solution
The technology of the present invention is by the prior art first, and the minimum distance d on card between filtering bag holes and filtering bag holes is carried out It is greatly optimized.Because the parameter is to ensure same efficiency of dust collection, the parameter for investing most critical is influenced.In the prior art The spacing is typically designed as d=70-80mm, by reducing spacing, it can be made to be optimized between 10-50mm, generally common model It encloses for 20-40mm.
Arrangement spacing d between filter bag and filter bag is taken small, is that technical field designer pursues always, but always Since it is difficult there is the obstacle of breakthrough to be, one end of filter bag and bag cage is suspended from card, and (card refers to will be empty inside dust collector box body Between be divided into filter before smoke chamber and filter after air-purifying chamber interval steel plate) on, be almost hinge connection;And the other end, to adapt to Air-purifying chamber replaces the filter bag damaged during production run, is generally configured to free end, and general filter bag length online In 6-8m.In free end side, there is also Lateral Winds, in addition location tolerance is manufactured, when filter bag spacing d is less than 70mm, filter bag Between be easy mutually collision in the process of running, this collision must avoid, and otherwise, filter bag can be due to mutually colliding quickly It grinds away failure.
Technical proposal that the invention solves the above-mentioned problems is between filter bag and filter bag, by the outer surface of filter bag Spacing block is set【30】With wear-resistant pad【31】, as shown in Figure 1.Make filter bag in mutual collision, only spacing block【30】With it is wear-resistant Pad【31】It is in contact, it is ensured that the possibility being not in contact between the filtering material of filter bag.The thickness of wear-resistant pad generally 1-2mm it Between, the thickness of spacing block according to filter bag sets the spacing at spacing block and subtracts the thickness of twice of wear-resistant pad subtracts spacing block on filter bag again Depending on theoretical gap between the wear-resistant pad of adjacent filter bag, the gap generally takes 3-10mm.The filter bag of bag filter is most It is vertically disposed, single layer spacing block or multilayer spacing block, bottom spacing block and wear-resistant pad can be designed according to the length of filter bag Position be arranged at the change in bag cage from cylindricality to taper, as shown in Figure 1a.The fit system of spacing block and wear-resistant pad is unlimited, On vertical view, can also there be spacing block by existing wear-resistant pad on a filter bag, as shown in Figure 1 b;It can also a part of filter bag setting Spacing block, wear-resistant pad is arranged in a part, but the principle being arranged is that spacing block and wear-resistant pad correspond, adjacent to each other, such as Fig. 1 c It is shown.If bag cage is that polygon can be in filter bag plug inner face to enable spacing block to be accurately distributed on each face of bag cage On to be provided with section be ellipse or polygon starting taper and the interior locating rod that is linked together accordingly, in this way, bag cage is when mounted, The torsion that filter bag will be automatically corrected, makes spacing block accurately be distributed in design position.
Spacing block is arranged with wear-resistant pad solution while ensureing that filter bag does not collide mutually conscientiously, well in the present invention Solves the functional requirement for replacing filter bag online in equipment operation, because spacing block and wear-resistant pad are all integrally fixed on filter bag , it can replace and dismount with filter bag, being not required to very important person enters operation in smoke chamber babinet, complete with the operating type that changes filter bag at present It is exactly the same.
Spacing block can select to be made of one or be provided separately with wear-resistant pad according to the shape difference of bag cage, and material can be Rubber, steel, plastics, textile of chemical fibre material, nylon material, can also be magnetic material etc., selected materials Make every effort to wear-resisting, anti-corrosion, adapt to work condition environment condition.Being fixed on filter bag outer surface mode can be gluing, sewer, can also lead to The slash pocket of filter bag exterior surface sewing is assemblied on the outer surface of filter bag.Preferably, spacing block selects stainless steel substrates brake forming Manufacture or rubber, plastic shaping manufacture, the slash pocket sewed by outer surface are assemblied on the outer surface of filter bag.
The present invention has ready conditions under the premise of small spacing not gouging abrasion between solving filter bag filter bag and bag cage making Very little, to increase filter bag area amount in unit space babinet.What previous engineer dare not do filter bag and bag cage too small (refers to In rugosity), the reason is that the thin rigidity of filter bag becomes smaller, be more easy to collide, filter bag perimeter used at present be generally 370-600mm it Between, and the technical program has ready conditions and the filter bag perimeter is designed in 100-360mm.If in the preferable situation of back-blowing condition Under, filter bag length can also be lengthened to 6-12m, generally common 9m.
Being greatly optimized for Technology of Fabric Filter economic indicator can be realized by foregoing invention technology, can make babinet unit space Increase 2-4 times of setting filter bag area, 35-45%, the near 0.25-0.35m/min of filtration velocity are saved in investment, therefore are substantially saved more Electricity, and can easily realize minimum discharge, make outlet dust concentration be expected to reach 2mg/Nm3Below.
To further increase filter bag area, the line at filter bag stud point of contact can be equilateral triangle, square, diamond shape, Regular pentagon, flat rectangle, class ellipse etc., filter bag be packed into bag cage after cross sectional shape it is as shown in Figure 2 a.
