Abstract
The invention relates to a continuous preparation system for lime slurry having a fixed concentration, and solves the problem that the prepared lime slurry is insufficient by using a large smoke semidry deacidifying process. The prepared lime slurry is delivered to a rotary atomizer through the system. The system comprises a lime cabin of which the lower part is provided with an activating hopper; the lime cabin is connected with a curing tank through a feeder; the curing tank is also connected with a tap water inlet tube; an outlet of the curing tank is connected with a storage tank through a vibrating filter; and the storage tank is connected with a lime slurry pump. The system is characterized in that: the curing tank is divided into two curing chambers through a chamber-dividing clapboard; and the two curing chambers are provided with a stirrer respectively.
Description
(1) technical field
The present invention relates to waste incineration and generating electricity and steel mill's blast furnace sinter machine flue-gas desulfurizing engineering technical field, be specially a kind of continuous preparation system for lime slurry having fixed concentration.
(2) background technology
Garbage incinerating power plant and steel mill's blast furnace sinter machine flue gas desulfurization technique have various ways at present, wherein a kind of form is a rotating spraying formula semidrying deacidifying flue gas technology, and this process system is during deleterious sour gas takes place in the lime white that utilizes the high speed rotating atomizer to eject to decide concentration and the flue gas and chemical reaction.Original lime slurry having fixed concentration preparation process prepares in batches, the lime white for preparing is stored in the storage tank that has whipping appts, this technology can satisfy service requirements for the little situation of lime white demand, but when using for the big deacidifying flue gas of lime white demand, just need the big storage tank of floor space, it can not satisfy the needs of technology.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of continuous preparation system for lime slurry having fixed concentration, it has solved, and lime white prepares under-supply problem in the big exhaust gas volumn semidrying deacidifying process, can continuously the lime white for preparing be flowed to rotary sprayer by this system.
Its technical scheme is such, it comprises lime silo, described lime silo bottom is equipped with the activation bucket, described lime silo connects the slaking jar by material feeder, described slaking jar also is connected with the tap water water inlet pipe, and described slaking jar discharge outlet connects hold-up vessel by vibration filters, and described hold-up vessel connects lime slurry pump, it is characterized in that: be separated into two curing chambers by the locellus wallboard in the described slaking jar, be separately installed with agitator in described two curing chambers.
It is further characterized in that: described slaking jar is provided with the overflow discharge outlet; Described material feeder is the duplex tube helix material feeder of weighing; In the described hold-up vessel agitator is installed.
A kind of continuous preparation system for lime slurry having fixed concentration of the present invention, it can prepare lime slurry having fixed concentration in enormous quantities continuously, does not need the storage tank that uses floor space very big, satisfies in the big exhaust gas volumn semidrying deacidifying process processing requirement to the lime white preparation; It is separated into two curing chambers with the lime slaking jar, all is equipped with agitator in two curing chambers, can fully stir, and guarantees the continuous preparation of lime white; The slaking jar adopts goes up the overflow discharge outlet, also can regularly discharge with oarse-grained contamination precipitation to the slaking pot bottom, prevents that further impurity from entering strainer, guarantees the continuous preparation of lime white; In addition, adopt the steady material feeder of duplex tube helix, guaranteed that further lime white prepares continuously.
(4) description of drawings
Fig. 1 is a kind of continuous preparation system for lime slurry having fixed concentration structural representation of the present invention.
(5) embodiment
See Fig. 1, it comprises lime silo 1 a kind of continuous preparation system for lime slurry having fixed concentration of the present invention, lime silo 1 bottom is equipped with activation bucket 2, lime silo 1 connects slaking jar 8 by material feeder 5, slaking jar 8 also is connected with tap water water inlet pipe 7, and slaking jar 8 discharge outlets connect hold-up vessel 15 by vibration filters 13, and hold-up vessel 15 connects lime slurry pump 17, wherein be separated into two curing chambers by locellus wallboard 10 in the slaking jar 8, be separately installed with agitator 9 in two curing chambers.Slaking jar 8 is provided with overflow discharge outlet 12; Material feeder 5 is the duplex tube helix material feeder of weighing; Agitator 14 is installed in the hold-up vessel 15; Among the figure, 3 is automatic switch valve, and 4 is the star discharge valve, and 6 is material feeder gate out switch valve, and 11 are slaking jar impurity discharge outlet, 16 hold-up vessel impurity discharge outlets.
A kind of continuous preparation system for lime slurry having fixed concentration of the present invention, lime and water successively enter the slaking jar, after agitator fully stirs slaking, discharge from last overflow discharge outlet, enter hold-up vessel after vibration filters is filtered, and realize the continuous preparation of lime white; In order to ensure the lime white steady concentration, need the amount of strict control lime and water, the amount of lime is controlled by the duplex tube helix material feeder 5 of weighing, and water comes dominant discharge by under meter and control valve; In depickling or devitrification process, different flue gas flows are all different with the content of harmful sour gas constantly, thus to the requirement difference of lime white, by automatic control system control lime and water to measuring.
