Description
Technical field
The present invention relates to production of carbon black water treatment technologies, and in particular to the processing of the bright water of tar in a kind of carbon black generating process
Device and method.
Background technique
The primary raw material of China's production of carbon black is coal tar, and coal tar is the primary raw material of coal chemical industry, and ingredient reaches
Up to ten thousand kinds, mainly contain the aromatic hydrocarbons such as benzene,toluene,xylene, naphthalene, anthracene and aromatic series oxygenatedchemicals (such as phenol phenol generalization
Close object)；Coal tar is divided into different boilings by the gas chromatographies such as nitrogenous, sulfur heterocyclic ring compound, the method that fractionation can be used
The fraction of point range.Coal tar moisture average out to 2.5~3.5%, water are inorganic matters, and coal tar is organic matter, and the two specific gravity
It is different.Thus can occur to stand dehydration during tar storage, the specific gravity of water is low, water layer in the top of tar tank, top
Water layer is the bright water of tar；The specific gravity of coal tar is high, and oil reservoir is in the lower section of tar tank.The bright water main component of tar is ammonia
Water, there are also a small amount of light oils, the metal ions such as chloride ion, potassium sodium Ca, Mg and Fe, and wherein chloride ion content is 1000mg/l, chloride ion
Caused by penetrating the oxide layer and protective layer and interior metal generation electrochemical reaction of metal surface；Meanwhile chloride ion contains one
Fixed hydration energy is easily attracted to the hole of metal surface, crack is squeezed and replaces oxygen in chlorination layer, insoluble oxidation
Object becomes soluble chloride, so that passivation state surface is become nonreactive surfaces, causes the adverse reaction extremely bad to product；Carbon black is received
Collection, purification, granulation, dry, conveying are all environment of the chlorine ion concentration >=200mg/l at 250 DEG C in closed metal space
It is doubled and redoubled in the corrosiveness to stainless steel, therefore rationally controls the use of the bright water of tar.
The method that the prior art handles the bright water of tar is that bright water is arranged to the bright water of tar from 10 top discharge outlet of tar tank
It is put into bright water receiving tank 11, the ball valve of a DN15 is installed on bright 11 outlet line of water receiving tank, is guaranteed by regulation ball valve bright
Water continuous uniform is discharged into water process ponding well 12, will be mixed after mixing with other water for flowing into ponding well by immersible pump
Water squeezes into water process primary sedimentation tank 13, and water bright so just have passed through the dilution of continuous uniform；Using other hydrolysis acidifications, connect
The water treatment procedures such as touching oxidation enter water process secondary settling tank 14；Subsequently into 600 water pots 15 of production of carbon black, then pass through water pump 16
By treated, water is used for production of carbon black, is mainly used for a chilling, secondary chilling, granulation water.
The prior art mainly using increase receiving tank by the bright water of tar be diluted it is up to standard after use, in the bright water of tar
Gas escape, and chloride ion poor processing effect are had at water process containing ammonium hydroxide, light oil, it is unfriendly to environment；Environmental requirement
Promotion, this processing method certainly will be denied.
