Detailed description of the invention
In order to understand the present invention better, explain embodiments of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of wet desulphurization pulping system, comprise limestone powder bin 1, slurrying pond 5, described limestone powder bin 1 is fixing with on ground 6 by steel construction supporting leg 10, the vertical lower of limestone powder bin is located in described slurrying pond 5, rotary feeder 3 of weighing is provided with between described limestone powder bin 1 and slurrying pond 5, limestone powder bin 1 bottom is connected with blanking magazine 13, blanking magazine 13 bottom is provided with push-pull valve or gate valve 2, the bottom of described push-pull valve or gate valve 2 is provided with lower flange 7, described top of weighing rotary feeder 3 is provided with upper flange 8, described push-pull valve or gate valve 2 with weigh rotary feeder 3 by lower flange 7, upper flange 8 connects, described rotary feeder 3 bottom of weighing is provided with tremie pipe 9, described tremie pipe 9 is connected with rotary feeder 3 of weighing by flange 11, described tremie pipe 9 extends downward slurrying pond 5, agitator 4 is provided with in the middle of top 12, described slurrying pond 5, ground less than 6 is located in described slurrying pond.Top, described slurrying pond 5 is provided with the bracing frame be flexibly connected with it, and described agitator 4 is connected with bracing frame.Described slurrying pond 5 adopts xoncrete structure to make.The present invention adopts rotary feeder of weighing to substitute weigh screw(-type) feeder or belt feeder feed of weighing, arrange for stock tank below rotary feeder of weighing, thus save investment and floor space to greatest extent, shorten transport path, decrease " putty " and " reentrainment of dust " phenomenon, reduce energy consumption.
Due to pulverized limestone water-soluble generation chemical reaction release heat, and produce CO
2gas.Therefore have a large amount of water vapours produce and carry dust.Be intermittent because pulverized limestone is reinforced, therefore interval after the addition was finished, above-mentioned fog dust will rise along tremie pipe 9, causes thus after the lime stone powder moisture absorption in place's deposition foulings such as tube wall and push-pull valves 2.Cause push-pull valve 2 cannot open and the blocking of tremie pipe 9 caking.Slurrying pond, as provision for sealing, in order to ensure internal and external pressure balance, is provided with drain 13 at its top, and above-mentioned fog dust also can be excessive along drain, causes secondary pollution.
In order to avoid the problems referred to above, the present invention arranges guard seal device in tremie pipe 9 outlet, described guard seal device comprises cylinder 14, spacing collision block 16, magnetic valve, control system, described cylinder is located at the top 12 in slurrying pond, the piston rod 15 of cylinder is connected with the sealing baffle 18 of bottom, sealing baffle 18 coordinates with blanking port, blanking nozzle flange is provided with sealing gasket 17, spacing collision block 16 is bolted with the flange of cylinder bottom, sealing baffle opens or closes and has been elevated by solenoid control cylinder, and interlock with electronic rotary feeder 3 of weighing, namely when rotary feeder feed while, sealing baffle is opened, while reinforced end rotary feeder is closed, drive sealing baffle to close by magnetic valve delays time to control cylinder, thus avoid the above-mentioned fog dust in gap fed in raw material to cause the problem of the caking such as tube wall and batcher push-pull valve blocking along tremie pipe rising.Because sealing baffle adopts and tremie pipe independently structure, both alleviated construction weight, reduced cylinder specification, decreased compressed air consumption; Be convenient to again cleaning and maintenance maintenance.Arrange spacing collision block 16 be position, stroke end in order to limit cylinder and prevent cylinder from driving baffle plate to stop time impact to the generation destruction of material blanking tube.
The top in described slurrying pond is provided with bending drain 13, in the straight length pipeline of drain, be provided with mesh mist eliminator 19, can above-mentioned fog and dust be removed, and be provided with wash tub pipe nozzle and regularly discharge water flushing, prevent the blocked rear inefficacy of mesh mist eliminator, thus improve site environment.Because slurrying itself needs constantly to supplement fresh water (FW), above-mentioned a small amount of flushing water one of can be originated as moisturizing, thus can not cause extra water consumption.
Described slurrying pond is provided with overfall 20, and the opening of described overfall is located at the position of slurrying pond below normal level 1-3m, and overfall is connected with discharge trench 21 by adapter.Present invention improves over the structure of overfall, at the following mouthpiece of slurrying pond normal level 1-3m, discharge trench is caused again by adapter, utilize the principle of fluid-tight, prevent the fog flour dust overflow produced in pulping process, thus overcome the following problem existed in prior art, namely in order to prevent, liquid level is too high must arrange overfall in slurrying pond, overfall conventional in prior art is arranged on high liquid level place, causes the excessive of fog dust in pulping process, thus forms the problem of reentrainment of dust.
Feed flow process of the present invention: outsourcing agstone is shipped by tank car, by Geldart-D particle discharging, powder enters and is stored in lime stone point storehouse, has two bifurcateds at the bottom material-falling hopper in powder storehouse, thus has the using and the reserved two material inlets.Feed-stock outlet connects push-pull valve, and push-pull valve connects rotary feeder, batcher feed by MEASUREMENT SYSTEM CONTROL feeding coal, batcher connects tremie pipe, in tremie pipe access slurrying pond, powder falls into slurrying pond and mix with water and abundant dissolving makes suspension, completes pulping process.In order to make agstone and the abundant mixed dissolution of water, in slurrying pond, being provided with agitator, can ensureing that slurries mix.
By reference to the accompanying drawings the detailed description of the invention of invention is described although above-mentioned; but not limiting the scope of the invention; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
