Description
Technical field
The utility model is related to mother liquor recovering device field more particularly to a kind of alkaline mother liquor recovery devices.
Background technology
In fine chemistry industry especially in the production of dyestuff intermediate, many reduction reactions（Such as disperse B-56, B-73 reduction
Reaction）It is carried out as reducing agent with vulcanized sodium or NaHS all in highly basic medium.The alkalinity of its mother liquor is very strong,
The method of generally use is at present：" three wastes " are directly entered to be handled.Its major defect of this method is：Not only to consume
A large amount of acid, increases production cost, and may also generate that irritation is very strong and poisonous gas hydrogen sulfide, gives surrounding
Environment cause sizable harm.
The shortcomings that in order to overcome in the prior art, needs to design a kind of alkaline mother liquor recovery device.
Utility model content
In order to overcome the defects of the prior art, a kind of alkaline mother liquor recovery device is provided.
The utility model is realized by following proposal：
A kind of alkaline mother liquor recovery device, including reaction kettle, upper end and liquid caustic soda measuring tank and the sulphur of the reaction kettle
Change sodium dissolving pan and correspond to connection, the lower end of the reaction kettle is correspondingly connected with by pipeline and filter press, in the reaction kettle and pressure
Filter pressing pump is correspondingly provided on pipeline between filter, the mother liquor outlet of the filter press connects with disposing mother liquor slot by the way that pipeline is corresponding
Logical, the disposing mother liquor slot passes through pipeline connection corresponding with reaction kettle.
Be correspondingly provided with recovery pump on pipeline between the disposing mother liquor slot and reaction kettle, the disposing mother liquor slot with
It is correspondingly provided with accurate filter on pipeline between recovery pump.
The connection corresponding with waste water collection tank of the wastewater outlet of the filter press.
The connection corresponding with solid material collecting tank of the solid matter outlet of the filter press.
The beneficial effects of the utility model are：
A kind of alkaline mother liquor recovery device of the utility model uses mother liquid recycle technology, a large amount of mothers using recycling
Liquid is turned waste into wealth, and production cost is not only greatly reduced, while also mitigating the pressure of " three wastes ", and will not be destroyed and be influenced
The environment of surrounding.
Description of the drawings
Fig. 1 is a kind of system structure diagram of alkaline mother liquor recovery device of the utility model；
In figure：1 is liquid caustic soda measuring tank, and 2 be vulcanized sodium dissolving pan, and 3 be reaction kettle, and 4 be filter pressing pump, and 5 be filter press, and 6 are
Disposing mother liquor slot, 7 be recovery pump, and 8 be waste water collection tank, and 9 be accurate filter, and 10 be solid material collecting tank.
Specific implementation mode
The utility model is further illustrated with reference to Fig. 1 and specific embodiment：
A kind of alkaline mother liquor recovery device, including reaction kettle 3, the upper end of the reaction kettle 3 and liquid caustic soda measuring tank 1 and
Vulcanized sodium dissolving pan 2 corresponds to connection, and the lower end of the reaction kettle 3 is correspondingly connected with by pipeline and filter press 5, in the reaction kettle
Filter pressing pump 4 is correspondingly provided on pipeline between 3 and filter press 5, mother liquor outlet and the disposing mother liquor slot 6 of the filter press 5 pass through
Pipeline corresponds to connection, and the disposing mother liquor slot 6 passes through pipeline connection corresponding with reaction kettle 3.
It is correspondingly provided with recovery pump 7 on pipeline between the disposing mother liquor slot 6 and reaction kettle 3, in the disposing mother liquor
Accurate filter 9 is correspondingly provided on pipeline between slot 6 and recovery pump 7.The wastewater outlet and waste water collection tank of the filter press 5
8 correspond to connection.The connection corresponding with solid material collecting tank 10 of the solid matter outlet of the filter press 5.
Accurate filter can be specific to tie with waste water purification devices such as resin filtering, reverse osmosis units in actual use
Structure and principle are known technology, and details are not described herein.
The specifically used process of the utility model is：
It by material completely reacted in reaction kettle, squeezes into filter press with filter pressing pump and is filtered, dried up as possible with compressed air
（Generally want blow pressure half an hour）Mother liquor in filter press in solid material, the alkaline mother liquor of filter press flow into mother liquor by pipeline and return
Slot is received, detects that the content of liquid caustic soda, vulcanized sodium in disposing mother liquor alkali in groove aqueous mother liquor, the alkaline mother liquor in disposing mother liquor slot pass through again
It is delivered to reduction reaction kettle with recovery pump after accurate filter filtering, the raw material as next batch reaction；Add corresponding liquid caustic soda
And vulcanized sodium, the liquid caustic soda and sodium sulfide amount that make reach the technological requirement of reaction, then carry out the restoring operation of next batch.By press filtration
Solid material in machine is washed with hot water, and washing lotion is collected etc. pending into waste water collection tank；Solid material enters solids
Expect that collecting tank etc. is pending.
Alkaline mother liquor recovery device of the present apparatus as reduction reaction in chemical process, to complete alkaline mother liquor
Recovery is particularly suitable for the very strong reaction of alkalinity.First completely reacted material is filtered, alkaline mother liquor is through piping stream
Enter disposing mother liquor slot, is applied mechanically as next group.The alkaline mother liquor of collection, then slightly add（Or it does not add）Fresh liquid caustic soda and vulcanization
Sodium, the liquid caustic soda and sodium sulfide amount that make reach the technological requirement of reaction.Next group reaction raw materials are can be used as, production cost is reduced, carries
High enterprise competitiveness, remarkable in economical benefits.
Solid material in filter press is then just washed with hot water, and the concentration of alkali is relatively low in waste water at this time, then
Into waste water treatment system, mitigate the pressure of " three wastes " processing.And it avoids generating a large amount of irritations very strong and toxic
Hydrogen sulfide gas, will not destroy and influence the environment of surrounding.
Although having done more detailed elaboration to the technical solution of the utility model and having enumerated, it should be understood that for
For those skilled in the art, modification is made to above-described embodiment or uses equivalent alternative solution, this skill to this field
Be for art personnel it is clear that on the basis of without departing from the spirit of the present invention these modifications or improvements, belong to
In the range of the requires of the utility model protection.
