Technical field

The invention belongs to chemical production technical fields, and in particular to a kind of strontium barium salt subsequent leaching, production system of slagging tap and Production technology.

Background technique

It is most of at present that strontium carbonate, barium carbonate are produced using carbon reduction method in strontium carbonate, barium carbonate, using also Former method must just use kiln roasting reduction.Raw material completes the clinker (strontium sulfide/barium sulphide formed after roasting reduction in rotary kiln Solid mixture of the content 40%~70%), residual temperature is probably at 800 DEG C or so, it is generally the case that is interrupted clinker with driving Property addition leaching slot in, finally to leaching slot in repeatedly plus water extraction obtain strontium sulfide/barium sulfide solution (vulcanization content of strontium be The solution of 55~75g/L, barium sulphide content are 78~106g/L).Strontium slag, barium slag after leaching generally use gravity dehydration (certainly So drain) cinder field directly is transported to the slag car or other means of transports afterwards.This production technology has the disadvantage in that

1, hopper is needed to shuttle during rotary kiln discharging between rotary kiln and leaching slot, during this, no Can only amount of heat be gone out to environmental radiation, influence of poor quality is caused on operating environment, it is also necessary to frequent mobile clinker bucket, operative employee People's heavy workload buries biggish security risk.

2, the clinker quantity being added in leaching slot when leaching every time is more, and the heat of attached collection is big, is concentrating the mistake for adding water extraction Cheng Zhonghui generates a large amount of water vapour, incidentally plays a large amount of dust therewith, and in clinker sulfur dioxide gas scattered row, if plus It there is also material spray phenomenon when water is too fast.A large amount of vapor, dust and the sulfur dioxide generated in the process is to building ring Border can generate bad influence, cause heavy corrosion to leaching room frame, more have very big damage to workers ' health, there are biggish Safety and environmental protection hidden danger.

3, it due to being intermittent leaching, so the strontium sulfide/barium sulfide solution concentration leached is unstable, directly contributes subsequent The unstable and product quality of reaction it is unstable.

4, it cannot directly enter downstream processing since water content is also higher in strontium slag/barium slag, need to establish cinder field and stored up It deposits.The higher strontium slag/barium slag of water content can generate a large amount of infiltration worry water after entering cinder field, and a large amount of seep considers water recovery processing cost Height, difficulty are big, and will increase very big hidden danger to the ecological environment around cinder field.

5, also become waste water containing a large amount of strontium sulfide/barium sulfide solution in strontium slag and cannot efficiently use, thus cause strontium, The waste of barium element.

Summary of the invention

In view of the above-mentioned problems, the invention proposes it is a kind of strontium barium salt subsequent leaching, the production technology slagged tap, realize clinker Continuous discharge, subsequent leaching and strontium slag/barium slag continuously slag tap, are dehydrated, and finally obtain water content very low strontium slag/barium slag and strontium The recycling of barium salt solution.
