Description
Technical field
The utility model relates to desulfurizer technical field.
Background technology
At present, wet method lime stone-gypsum doctor treatment is most widely used at steel industry, the primary raw material adopting is lime, in use, because the removal of impurity in lime is generally all not bery high, part larger particles impurity enters desulfuration absorbing tower, so cause slurries anticorrosive coat and the circulating pump in wear-out failure absorption tower in cyclic process that contains larger particles impurity, these wearing and tearing have improved equipment failure rate and repair and replacement cost greatly, are unfavorable for the normal operation of producing.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of desulfurization slurry filter, this apparatus structure is simple, making is easy, can effectively remove the impurity in desulfurization slurry, reduces the wearing and tearing of slurries to absorption tower and circulating pump, reduce equipment failure rate, reduce maintenance maintenance cost.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of desulfurization slurry filter, comprise housing, be provided with the tubular filter screen of upper and lower opening in described housing, the two ends up and down of this tubular filter screen are flexibly connected with housing top board and base plate respectively; The port of export of slurry feed pipe from extend in tubular filter screen, slurries discharge nozzle is communicated in the lower sides of housing, sludge outlet is located at the lower end of tubular filter screen and is fixedly connected with housing.
The first control valve entering for controlling slurries is installed on slurry feed pipe; The second control valve flowing out for controlling slurries is installed on slurries discharge nozzle; The electrically-controlled valve of discharging for filter residue is installed at sludge outlet.
Described tubular filter screen is 20-300 order.
Described sludge outlet is pyramidal structure, and its large port footpath is greater than tubular filter screen diameter.
The beneficial effect that adopts technique scheme to produce is: this device adopts stainless steel tubular filter screen to realize the impurity in slurries is effectively filtered, simple in structure, make easily, and can clear up in time the impurity filtering, reduce the wearing and tearing of slurries to absorption tower and circulating pump, reduce equipment failure rate, the maintenance maintenance cost of minimizing to equipment, has positive effect to the normal operation of producing and the reduction of production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Mark in figure: 1, the first control valve; 2, slurry feed pipe; 3, housing; 4, tubular filter screen; 5, slurries discharge nozzle; 6, the second control valve; 7, electrically-controlled valve; 8, sludge outlet; 9, baffle plate; 10, cover plate.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
In the raw material lime adopting due to wet method lime stone-gypsum doctor treatment, contain a large amount of impurity, do not remove or remove unclean, all can cause the wearing and tearing of desulfurizing tower and the circulatory system, strengthen repair and replacement cost, be unfavorable for the normal operation of producing, also can affect the effect of desulfurization.
This device case 3 is the cube structure of sealing, as Fig. 1, shown in Fig. 2, in the middle of casing, have the opening corresponding with tubular filter screen 4, opening part is provided with cover plate 10, cover plate 10 is bolted on the top board of housing 3, tubular filter screen 4 is 30-200 object stainless steel tubular filter screen, the upper end edge of tubular filter screen 4 is evenly distributed in grab, this grab is hooked in the groove that top board 10 open circumferential arrange or on flange, housing is welded with the baffle plate 9 that a circle is evenly distributed in the middle of 3 bottoms, the diameter of the baffle plate 9 of this circle distribution and tubular filter screen internal diameter match, tubular filter screen 4 lower ends can be stuck in outside baffle plate 9, this design guarantees easily installation and removal taking-up of tubular filter screen 4, easy cleaning and replacing, also can the upper end of tubular filter screen be fixed on the top board of housing 3 by the fixing mode of bolt, tubular filter screen 4 is not fixed with also adopting tubular filter screen 4 lower ends being connected of housing 3, the fixing mode in upper end only, take and facilitate installing/dismounting as object, slurry feed pipe 2 stretches in tubular filter screen 4 from the fluting of cover plate 9, slurries enter in tubular filter screen 4 through slurry feed pipe 2, interior through precipitation clarification at tubular filter screen 4, impurity sinks to sludge outlet 8, slurries after clarification enter in the cavity of square casing through tubular filter screen 4, from slurries discharge nozzle 5, are discharged in lime slurries holding vessel.Sink to the impurity of sludge outlet 8 through the timing automatic discharge of electrically-controlled valve 7.
This device middle shell 3 also can be the circular tank shape that is provided with end socket, and end socket is connected with housing 3 bolts, and end socket is provided with the ring flange being connected with slurry feed pipe 2, replacing tubular filter screen 4 for convenience detach; Sludge outlet is pyramidal structure, and its large port footpath is greater than tubular filter screen diameter, and can weld or adopt the fixing mode of bolt be fixed on housing 3 below, at osculum end, electrically-controlled valve 7 is installed, regularly the impurity at sludge outlet place is sunk in cleaning.
This device adopts stainless steel tubular filter screen to realize the impurity in slurries is effectively filtered, simple in structure, make easy and practical, can clear up in time the impurity filtering, reduce the wearing and tearing of slurries to absorption tower and circulating pump, reduce equipment failure rate, the maintenance maintenance cost of minimizing to equipment, all has positive effect to the normal operation of producing and the reduction of production cost.
