Description
Technical field
The present invention relates to a kind of cleaner, especially relate to the cleaner of cement building material.
Background technology
In the prior art, its dedusting of the cleaner of dust such as cement mainly is to utilize the filter bag Chalk-dust filtering, and the deadweight sinking dedusting that utilizes dust in the dust natural flow process, wherein the filter bag Chalk-dust filtering can increase the replacement cost of filter bag, and the deadweight sinking dedusting of dust does not have consumables cost, but the deadweight subsidence velocity of dust is slow, and inefficiency does not satisfy instructions for use.
In addition, the filter bag Chalk-dust filtering of cement building material all adopts lower intake method, dusty gas moves upward from filter bag bottom, and obviously the bottom of filter bag, middle part and the top rate of filtration can be different, and this situation can make the local area wind speed too high and affect life-span and the resistance of filter bag.More seriously, the dust granules thickness has certain distribution in the dusty gas, and lower intake method can make most crude particle be deposited on the filter bag bottom and fine grained is deposited on filter bag top.By the pulse dust cleaning principle as can be known, the more even then permeability of dust layer large or fine granule and the ash-removal effect that are adsorbed on the filter bag surface are better, obviously above the distribution is a kind of defective, and the longer this defective of filter bag is more obvious, lower air intake mode also can produce second adsorption in deashing process, shorten the filter bag life-span, increased maintenance cost.
Summary of the invention
The present invention is according to above deficiency, a kind of cleaner with flow rotation is provided, this cleaner has increased the flow rotation parts, by flow rotation dust is focused on the metastable air-flow of air-flow center as much as possible, the dust concentration at air-flow center increases, accelerate, the peripheral dust concentration of swirling eddy reduces, and carries out final dusting by the air-flow tangential direction in side air intake mode.
Technical scheme of the present invention is:
A kind of cleaner with flow rotation, comprise: casing, the bracing frame of casing, the top of casing is provided with division board, this division board is divided into clean area and dust district with casing, the dust district is by middle housing, symmetrical left box body and right case form and isolate by the first vertical isolation plate, be fixed with several filter bags on the division board of left box body and right case, the bottom is for bullet and be provided with outlet, the exit is provided with valve, the top of middle housing is provided with the dust import, the below is provided with the wind passage mouth that dust enters left box body and right case, the bottom is provided with the outlet with valve, clean area is provided with the pure air outlet, be fixed with reducing motor on the division board of middle housing, the turning cylinder of reducing motor is fixed with the rotating shaft that stretches into middle housing, and rotating shaft is fixed with some blades by cross bar.
The top edge of described blade is lower than the dust import, and lower limb is higher than the bullet of left box body and right case, and width of blade and the radius of gyration satisfy and to be positioned at operation beyond half that maximum can the radius of gyration.
By regulating the speed of reducing motor, be convenient to dust so that the air-flow at air-flow center is relatively stable as far as possible, the flow rotation of air-flow periphery is convenient to dust to the air-flow central motion.
Also comprise the second vertical isolation plate, adjacent described the first vertical isolation plate of this second vertical isolation plate is fixed, and the bullet that the bottom of the top of the second vertical isolation plate and the first vertical isolation plate consists of upper air inlet passage, bottom and described left box body and right case consists of lower air inlet.
In order further to improve dust removing effects, the bottom of described middle housing is bullet, and described outlet with valve is arranged on the below of bullet.
The mounting structure of the first vertical isolation plate and the second vertical isolation plate has consisted of side air intake mode, this side air intake mode can make filter bag length be increased to 8m even longer, filter bag can be arranged De Gengmi, this is for the equipment of processing the large ash-laden gas scale of construction, can greatly reduce floor space, reduce the quantity of unit steel consumption and auxiliary equipment, thereby under the prerequisite that does not increase operation and maintenance cost, reduce one-time investment;
Because dusty gas enters from the side of filter bag, thereby make the sedimentation perpendicular direction of dusty gas flow direction and dust, compare dusty gas flow direction and the obvious ash-removal effect that improved of dust settling opposite direction of lower air inlet.Thereby greatly reduced the second adsorption in the deashing process, accelerated dust settling, these characteristics obviously reduce the deashing number of times, prolong life-span of the filter bag.
Side air intake mode is more evenly distributed the rate of filtration on filter bag surface and dust granules.Side air intake mode has then fundamentally solved this problem, makes the rate of filtration of filter bag even, can not make the local area wind speed too high, and the thickness of dust granules is evenly distributed, and the resistance of dust layer is little, and ash-removal effect is also better.
The side air intake is more suitable for the online ash removal mode.Because online ash removal can the full filter area of more effective utilization, reduce one-time investment and maintenance cost.The air valve door that does not have off-line ash-clearing in the online ash removal structure, equipment fault point is few, and mechanical resistance is low, can reduce operation energy consumption.Side air intake mode has reduced the second adsorption in the online ash removal process because the flow direction of dusty gas is consistent with the sedimentation perpendicular direction of dust, and this is that lower air intake mode is incomparable.
The beneficial effect that the present invention has is simple in structure, cost is low, maintenance cost is low, efficiency of dust collection is high.
