Abstract

The invention discloses a kind of method of calcium chloride in recycling permanent violet refined wastewater, the method for calcium chloride is permanent violet refined wastewater to be cooled to 3 ~ 5 DEG C material a is obtained by filtration in the recycling permanent violet refined wastewater;Material a is regulated and controled to calcium chloride mass percentage concentration and obtains material b for 10 ~ 30%;Material b is carried out to spray-fluidized-bed drying at a temperature of 300 ~ 350 DEG C and obtains object calcium chloride.The present invention effectively realizes wastewater zero discharge, calcium chloride is recycled completely, not only save raw material, reduce cost for wastewater treatment, and calcium chloride circulating repetition is used by carrying out scientific processing to permanent violet refined wastewater.After the present invention can be handled calcium chloride wastewater, anhydrous calcium chloride is obtained, purity can reach 98% or more, and water-insoluble is lower than 0.1%, can meet permanent violet purification and use.

Description

A method of calcium chloride in recycling permanent violet refined wastewater
Technical field
The invention belongs to chemical technology fields, and in particular to a method of calcium chloride in recycling permanent violet refined wastewater.
Background technique
Permanent violet crude product is blackish green powdery product, and pigment Violet 23 # product, the production can be obtained after refining pigmentation There are many ways to product are the organic high-grade pigment of dioxazine, refine pigmentation, one of which be using permanent violet crude product with Calcium chloride turns crystalline substance by ball mill grinding, and the powder material after grinding cooks iron through peracid, is obtaining face after washing is dry Expect purple 23# product.A large amount of chloride containing calcium waste water is generated in washing process.Calcium chloride wastewater is evaporated place by factory at present Reason, remaining calcium chloride waste residue cannot recycle use, therefore urgently develop a kind of method that can solve above-mentioned technical problem.
Summary of the invention
The purpose of the present invention is to provide a kind of methods of calcium chloride in recycling permanent violet refined wastewater.
The object of the present invention is achieved like this, the method for calcium chloride in the recycling permanent violet refined wastewater, including Following steps:
A, permanent violet refined wastewater is cooled to 3 ~ 5 DEG C and material a is obtained by filtration;
B, material a is regulated and controled to calcium chloride mass percentage concentration and obtains material b for 10 ~ 30%;
C, material b is subjected at a temperature of 300 ~ 350 DEG C spray-fluidized-bed drying and obtains object calcium chloride.
The present invention effectively realizes wastewater zero discharge, by chlorination by carrying out scientific processing to permanent violet refined wastewater Calcium recycles completely, not only saves raw material, reduces cost for wastewater treatment, and calcium chloride circulating repetition is used.The present invention can be with After calcium chloride wastewater is handled, anhydrous calcium chloride is obtained, purity can reach 98% or more, and water-insoluble is lower than 0.1%, can meet forever Gu purpurine system uses.
Specific embodiment
Below with reference to embodiment, the present invention is further illustrated, but the present invention is limited in any way, Based on present invention teach that it is made it is any transform or replace, all belong to the scope of protection of the present invention.
The method of calcium chloride in the recycling permanent violet refined wastewater, comprising the following steps:
A, permanent violet refined wastewater is cooled to 3 ~ 5 DEG C and material a is obtained by filtration;
B, material a is regulated and controled to calcium chloride mass percentage concentration and obtains material b for 10 ~ 30%;
C, material b is subjected at a temperature of 300 ~ 350 DEG C spray-fluidized-bed drying and obtains object calcium chloride.
The pressure filtered in step A is 0.1 ~ 0.5MPa.
Described is filtered into film filtering.
The filter sizes of the film filtering are 0.1 ~ 10.0 μm.
Regulation described in step B is evaporation or plus water.
The evaporation is evaporated when calcium chloride mass percentage concentration is lower than 10 ~ 30% in material a.
The evaporation is evaporated at 80 ~ 95 DEG C of temperature.
Described plus water is to carry out adding water when calcium chloride mass percentage concentration is higher than 10 ~ 30% in material a.
Described plus water is to add deionized water or plus secondary distilled water.
The hot blast temperature of the spray drying is 320 DEG C.
