Description
Technical field
The utility model relates to a kind of cleaner, especially relates to the cleaner of cement building material.
Background technology
In prior art, the cleaner 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, in dusty gas, the dust granules thickness has certain distribution, 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.From the pulse dust cleaning principle, more permeability and ash-removal effect are better to be adsorbed on the dust layer large or fine granule on filter bag surface, obviously above the distribution is a kind of defect, and the longer this defect 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.
The utility model content
The utility model, according to above deficiency, provides a kind of cement building material grinding machine bag filter, and this dust-precipitator adopts the side air inlet structure.
The technical solution of the utility model is:
A kind of cement building material grinding machine bag filter, comprise: casing, several bracing frames of casing, casing is by middle housing, symmetrical left box body and right case form, the bottom of left box body and right case is bullet and is provided with outlet, exit is provided with valve, the top of casing is provided with division board, this division board is divided into clean area and dust district by casing, be fixed with several filter bags on the division board of left box body and right case, the top in the dust district of middle housing is provided with the dust import, clean area is provided with the pure air outlet, be provided with the first vertical isolation plate between middle housing and left box body and right case, the second vertical isolation plate, this the first vertical isolation plate top is connected with division board, the wind passage mouth between middle housing and left box body and right case is left in bottom, adjacent the first vertical isolation plate of this second vertical isolation plate is fixed, the bottom of the top of the second vertical isolation plate and the first vertical isolation plate forms the upper air inlet passage, the bullet of the bottom of the second vertical isolation plate and left box body and right case forms lower air inlet.
In order further to improve dust removing effects, the bottom of described middle housing is bullet and is provided with outlet, and exit is provided with valve.
It is even longer that side air intake mode can make filter bag length be increased to 8m, filter bag can be arranged get Geng Mi, 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 reduce one-time investment under the prerequisite that does not increase operation and maintenance cost;
Because dusty gas enters from the side of filter bag, thereby make the dusty gas flow direction vertical with the sedimentation direction of 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, extend the filter bag life-span.
Side air intake mode is more evenly distributed the rate of filtration on filter bag surface and dust granules.Side air intake mode has 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 there is no 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, because the flow direction of dusty gas is vertical consistent with the sedimentation direction of dust, has reduced the second adsorption in the online ash removal process, and this is that lower air intake mode is incomparable.
The utlity model has beneficial effect simple in structure, that the filter bag life-span is long, efficiency of dust collection is high.
The accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
The specific embodiment
Now by reference to the accompanying drawings the utility model is further described:
As shown in the figure, a kind of cement building material grinding machine bag filter, comprise: casing, several bracing frames 8 of casing, casing is by middle housing 4, symmetrical left box body and right case form, the bottom of left box body and right case is bullet 71 and is provided with outlet, exit is provided with valve 72, the top of casing is provided with division board 3, this division board 3 is divided into clean area 1 and dust district by casing, be fixed with several filter bags 5 on the division board 3 of left box body and right case, the top in the dust district of middle housing 4 is provided with dust import 46, clean area 1 is provided with the pure air outlet, be provided with the first vertical isolation plate 41 between middle housing 4 and left box body and right case, the second vertical isolation plate 42, these the first vertical isolation plate 41 tops are connected with division board 3, bottom is left middle housing 4 and is entered the wind passage mouth 44 between left box body and right case, adjacent the first vertical isolation plate 41 of this second vertical isolation plate 42 is fixing, the bottom of the top of the second vertical isolation plate 42 and the first vertical isolation plate 41 forms upper air inlet passage 43, the bullet 71 of the bottom of the second vertical isolation plate 42 and left box body and right case forms lower air inlet 45.
