Description
Technical field
The present invention relates to a kind of production method of yellow sodium prussiate, and in particular to a kind of producer of coking industry yellow sodium prussiate
Method, belong to coking Product recycling technical field.
Background technology
The production of current domestic yellow sodium prussiate has two kinds of ferrous sulfate method and Powder by Iron Powder substantially, and ferrous sulfate method refers to utilize
20% or so Cymag is directly added into ferrous sulfate and reacted at 85-90 DEG C, then filters, and is concentrated by evaporation, crystallization, the work of centrifugation
Process.This method technique is simple, and raw material is easy to get, and is once widely adopted before 2000.But this method has two fatal defects：
When filtration difficulty, second, the caused sodium sulphate waste residue containing potassium ferrocyanide is too many, bad processing.So after 2000, progressively
Substituted by Powder by Iron Powder.Powder by Iron Powder refers to use less than the iron powder of 100 mesh with content 200-300g/L Cymag in 85-95 DEG C of reaction
The technique for directly generating yellow sodium prussiate.Concrete technology is：Cymag is made into content 200-300g/L liquid, existed with iron powder
To be reacted at 85-95 DEG C, reaction terminates, and reaction solution is sent to and makees double absorption, and double absorption liquid and iron powder made into secondary response, and two
After secondary response terminates, filtering is concentrated by evaporation, and is then crystallized centrifugation and is dried out finished product.
But in the technical process, it is a highly difficult thing that primary first-order equation liquid, which removes double absorption, because containing in liquid
A large amount of yellow sodium prussiate so that the conveying of the liquid, storage, absorb it is highly difficult, it is careless slightly will Crystallization Plugging.Technology controlling and process
Difficulty is very big.
The content of the invention
Overcome the deficiencies in the prior art of the present invention, technical problem to be solved are the technique of Powder by Iron Powder production yellow sodium prussiate
During, during primary first-order equation liquid removes double absorption, because containing a large amount of yellow sodium prussiate in liquid so that the liquid it is defeated
Send, store, absorb it is highly difficult, it is careless slightly will Crystallization Plugging, the problem of technique controlling difficulty is very big.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of production method of yellow sodium prussiate, it is raw
The mother liquor progress complete alternation during yellow sodium prussiate is produced, specific technical process is as follows：
A. the mother liquor feeding Cymag workshop section progress double absorption to get off will be centrifuged in production process；
B. two alkali contents are less than or equal to 5g/L after absorbing；
C. by double absorption mother liquor and 30%-32% Cymags by volume 3:1 is well mixed；
D. the feed liquid mixed is reacted with iron powder, 90-95 DEG C of reaction temperature, is reacted to cyanogen content and is less than or waits
Terminate when 1g/L, reaction solution sodium hydrate content is less than or equal to 50g/L at the end of reaction；
E. completely reacted feed liquid addition mixed liquor quality 1%-2% lime is directly filtered, and filtrate is crystallized, crystallization
Temperature is 35 DEG C；
F. centrifuge, by isolated finished product drying, mother liquor carries out double absorption.
This have the advantage that with prior art：The yellow sodium prussiate production method of the present invention changes the primary first-order equation liquid easily crystallized
Into centrifuge mother liquor, centrifuge mother liquor will not crystallize at normal temperatures, successfully solve during primary first-order equation liquid removes double absorption,
Because contain a large amount of yellow sodium prussiate in liquid so that the conveying of the liquid, storage, absorption is highly difficult, careless slightly to tie
The problem of crystalline substance blocks, and technique controlling difficulty is very big so that whole process becomes easily to operate.
The yellow sodium prussiate production method of the present invention eliminates double absorption, shortens technological process, eliminates evaporation and concentration,
Reduce process equipment, reduce production cost.
