Abstract
The utility model provides a refuse burning fume purifying lime mortar preparation device. During preparation, since temperature detection and control are performed and simultaneously the degree of feed control and system precision are enhanced, lime mortar slurry meeting the requirement on concentration is prepared. The preparation device comprises a preparation tank and a lime silo, wherein the preparation tank is internally provided with a stirrer; a water inlet and a lime inlet are formed in the upper part of the preparation tank; an outlet below the preparation tank is communicated to a storage tank and is provided with a preparation tank outlet valve. The preparation device is characterized in that an outlet below the lime silo is communicated to a lime metering screw, the lime metering screw is connected with the lime inlet, a feed screw of the lime metering screw is externally connected with a frequency converter, the frequency converter is externally connected with a controller, the controller is externally connected with a water inlet valve, the water inlet valve is connected with the water inlet through a pipeline, and an external water pipe of the water inlet valve is provided with a water volume meter.
Description
Technical field
The utility model relates to the technical field of lime slurrying, is specially a kind of garbage-incineration smoke purifying lime white preparation facilities.
Background technology
In waste incinerated smoke purification system semidry process, the lime slurry preparing evenly sprays into reaction tower through the spraying gun of high speed rotating.Lime white reacts with the sour gas such as HCl, SOx, HF in hot flue gas flow.The lime slurry evaporation of spraying is also cooled to approximately 150 ℃～160 ℃ by flue gas, and generate dry powdered reactant CaCl

4deng.This process of cooling also makes Dioxins, furans and heavy metal generation condense.Therefore lime white, in gas cleaning semidry process, has served as important role.But, unslaked lime is prepared lime white, it is a thermopositive reaction, existing lime white at preparation facilities by water once being filled up after calculating respectively lime weight, water weight, then sneak into lime and stir in preparation tank, now, in whipping process, it is large that too high temperature makes thermal meter detect error in dipping change, even can cause the weightlessness of weighing balance, may cause lime white change in concentration larger, affect the normal work of spraying gun.
Utility model content
For existing above-mentioned defect, the utility model provides a kind of garbage-incineration smoke purifying lime white preparation facilities, in its preparation process, increase detection and the control of temperature, meanwhile, improve the control of feed, the precision of raising system, prepares the satisfactory lime slurry of concentration.
A kind of garbage-incineration smoke purifying lime white preparation facilities, it comprises preparation tank, lime silo, in described preparation tank, agitator is housed, the top of described preparation tank has water-in, enter lime mouth, the below of described preparation tank has outlet and is communicated to preservation tank, described outlet is provided with preparation tank outlet valve, it is characterized in that: the below outlet of described lime silo is communicated to lime metering screw, described in being connected to, described lime metering screw enters lime mouth, the external frequency transformer of pressure feeding spiral of described lime metering screw, described frequency transformer external controller, the external water intaking valve of described controller, described water intaking valve connects described water-in by pipeline, the outer water tube of described water intaking valve is provided with water meter scale, the top of described preparation tank is provided with louvre, hot channel is equipped with in described louvre position, in described hot channel, be provided with exhaust fan, described exhaust fan connects described controller, temperature-detecting device is equipped with in the bottom of described preparation tank, described temperature-detecting device is circumscribed with described controller, described preparation tank entirety is placed in LOAD CELLS.
Adopt after the utility model, it is the singularity of suspension liquid according to lime white, takes into account the control of concentration, by water inlet, enter lime and change into into water, enter lime, intake, simultaneously, in its preparation process, increase detection and the control of temperature, make preparation system adapt to the preparation of unslaked lime and white lime, simultaneously, improve the control of feed, improve the precision of system, prepare the satisfactory lime slurry of concentration.
Accompanying drawing explanation
Fig. 1 is structural representation block diagram of the present utility model.
Embodiment
See Fig. 1, it comprises preparation tank, lime silo, agitator is housed in preparation tank, the top of preparation tank has water-in, enter lime mouth, the below of preparation tank has outlet and is communicated to preservation tank, it is characterized in that: the below outlet of lime silo is communicated to lime metering screw, lime metering screw is connected to into lime mouth, the external frequency transformer of pressure feeding spiral of lime metering screw, frequency transformer external controller, the external water intaking valve of controller, water intaking valve connects water-in by pipeline, the outer water tube of water intaking valve is provided with water meter scale, the top of preparation tank is provided with louvre, hot channel is equipped with in louvre position, in hot channel, be provided with exhaust fan, exhaust fan connects controller, temperature-detecting device is equipped with in the bottom of preparation tank, temperature-detecting device is circumscribed with controller, preparation tank entirety is placed in LOAD CELLS.
Its whole control process is as follows:
A, controller receive artificial default concentration value, calculate the water yield and the amount of lime that need, open water intaking valve;
B, add after a certain amount of water, start agitator;
C, open lime silo, start pressure feeding spiral that frequency transformer drives lime metering screw, start to supply with CaO by controller simultaneously, when pressure feeding spiral starts, high-speed cruising is supplied with most required amount of lime, and then low cruise is accurately supplied with remaining required amount of lime; In preparation process, detect the temperature of preparation tank inside by temperature-detecting device, in the time that temperature is high, in preparation tank, add water cooling; After temperature reduces, then close water intaking valve; When excess Temperature, stop pressure feeding spiral simultaneously, start exhaust fan, accelerate heat radiation, until temperature is got back to normal value, continue charging;
D, after required amount of lime all adds, open water intaking valve, water continues to add, and monitors, until reach required lime white concentration by water meter scale;
E, agitator continue to stir, and make solution stirring even;
F, open preparation tank outlet valve, weigh the quantitative lime white in preparation tank is put into and preserved tank by LOAD CELLS;
G, then start new batch circulation.
