Abstract
The invention discloses with carbide slag and handle the method that chlorine water prepares chlorinated lime and Calcium Chloride Powder Anhydrous, its main technical schemes is to utilize the chlorine water of white lime and chlorine industry to carry out chemical reaction slowly, and suction filtration obtains filter cake and fooling dry grinding to obtain the chlorinated lime finished product; And filtrate obtains the Calcium Chloride Powder Anhydrous finished product through underpressure distillation.When the present invention has thoroughly eliminated the useless chlorine water of chlorine industry and pollutes, can also create certain economic benefits for enterprise.
Description
Technical field:
The invention belongs to the technical field that three industrial wastes are handled, particularly handle the method that chlorine water prepares chlorinated lime and Calcium Chloride Powder Anhydrous with carbide slag.
Technical background:
At present, the chlorine water disposal of three wastes of chlor-alkali plant mainly neutralizes by alkaline matter, generally is to adopt carbide slag or white lime to neutralize to become Losantin and calcium chloride is directly drained.Administer completely, alleviated pollution though removed chlorine and chlorine root and hypochlorous acid and hypochlorite,, pollution substance still exists.The present invention can solve all objectionable impuritiess in chlorine water the inside completely, and makes it to turn waste into wealth and become Chemicals, has not only thoroughly eliminated source of pollution but also created economic worth.
Summary of the invention:
The purpose of this invention is to provide and a kind ofly handled the method that chlorine water prepares chlorinated lime and Calcium Chloride Powder Anhydrous, thoroughly effectively administered the pollution of the chlorine water of chlor-alkali plant, can also create economic worth for enterprise with carbide slag.
In order to realize above-mentioned purpose, two portions were about technical scheme of the present invention was divided:
The top technical scheme is:
With content is that carbide slag (8) and the unglazed chlorine water (9) of 65-85% is mixed in the treater (1) according to mass ratio 1: 5-15, carries out long-time 2-3 hour slow stirring reaction, till reaction liquid no chlorine root of check and hypochlorite.Add white lime until complete reaction if will continue in addition.
The lower section technical scheme is:
Carry out suction filtration to above-mentioned reaction solution this moment, the filter cake that suction filtration (2) obtains is a Losantin, drying (4) is pulverized (6) becomes the Losantin finished product, filtrate is that calcium chloride dihydrate obtains the Calcium Chloride Powder Anhydrous finished product through the dark distillation of decompression (3) through condensation (5), and it is for sale to enter finishing room (7) more respectively.
The chemical principle of its technical scheme is:

Description of drawings:
Accompanying drawing is a process flow diagram of the present invention, wherein
1---treater, 2---suction filter pump, 3---the underpressure distillation device, 4---moisture eliminator, 5---condenser, 6---pulverizer, 7---finishing room, 8---white lime drops into line, and 9---chlorine water drops into line.
Concrete embodiment:
Embodiment one: (unglazed chlorine water contains hypochlorous acid 1.2%; Contain chlorine 0.3%)
With 500 kilograms of content is that 75% carbide slag (8) and unglazed chlorine water (9) are mixed in the treater (1) according to mass ratio at 1: 10, carries out long-time 2-3 hour slow stirring reaction, till reaction liquid no chlorine root of check and hypochlorite.Add white lime until complete reaction if will continue in addition.
Carry out suction filtration to above-mentioned reaction solution this moment, the filter cake that suction filtration (2) obtains is a Losantin, drying (4) is pulverized (6) and is obtained 91.95 kilograms Losantin finished product, filtrate is that calcium chloride dihydrate obtains 26.39 kilograms Calcium Chloride Powder Anhydrous finished product through the dark distillation of decompression (3) through condensation (5), and it is for sale to enter finishing room (7) more respectively.
