Abstract
The present invention relates to a kind of is glass gall purifying method in the raw material production anhydrous sodium sulphate process with the glauberite.It is characterized in that in producing the technology of coarse sulfide water, adding lime, in the process for refining process, add carbon ammonium (or heavy alkali).The present invention compares with traditional method, can reduce cost widely, obtains good economic benefit.
Description
The present invention relates to a kind of is glass gall purifying method in the raw material production anhydrous sodium sulphate process with the glauberite.
At present, domestic is that raw material production anhydrous sodium sulphate process is with the glauberite: at first by the glauberite coarse sulfide water that gets made of stones, make purified product through operations such as refining, evaporation, crystallization, separation, dryings then.In the technological process of refining coarse sulfide water, play cleaning action by adding soda ash and caustic soda, but because soda ash and caustic soda are China's well sold and in short supply, industrial chemicals that valency is high for a long time, so with soda ash and caustic soda as scavenging agent, make the cost up of product, this is uneconomic to enterprise.
" Hami area salinization head factory chemical industry two factories " adopt lime and soda ash as scavenging agent.But its shortcoming has two: (1) this method can only replace caustic soda and caustic soda consumption and few with lime, so economic worth is little; (2) this method adopts the batch purification technology that falls behind, and equipment is huge, is difficult for being accepted by colleague enterprise.
The objective of the invention is to overcome the deficiency of above-mentioned prior art and a kind of novel method that reduces the refining sodium sulphate of product cost is provided.
Purpose of the present invention can reach by following measure: join in the ball mill (or bath) with glauberite ore, water with as the lime of scavenging agent and react, through leaching, make the coarse sulfide water that contains caustic soda after the filtration, and then will contain the coarse sulfide water of caustic soda and react as the carbon ammonium of another scavenging agent (or heavy alkali), make smart glass gall after filtering.
Chemical principle of the present invention is: lime can play causticizing reaction and generate caustic soda in glass gall with sodium sulfate; Carbon ammonium (or heavy alkali) can react again with caustic soda and generate soda ash, can play the effect except that Ca, Mg equally.
The present invention is described in further detail below in conjunction with embodiment:
Add together with glauberite ore, water with as the lime of scavenging agent and to carry out water mill in the ball mill and make ore pulp, filter and make the coarse sulfide water that contains caustic soda to send into original fluid container standby through stirring poor leaching, filter again.To make behind the solution coarse sulfide water that contains caustic soda in original fluid container as the carbon ammonium of another kind of scavenging agent (or heavy alkali) and join in the mixing tank and react, after the filtration of settling vessel and sand-bed filter, make smart glass gall, and send into smart glass gall storage tank and get final product.Chemical equation wherein is as follows:
More than be in the mill soaking technology of coarse sulfide water, to add lime, the smart glass gall that adding carbon ammonium (or heavy alkali) makes in process for refining.Also can in the molten technology of the cave of coarse sulfide water, add lime (be about to lime add bath soak the glauberite ore together with water and make the coarse sulfide water that contains caustic soda), in process for refining, add carbon ammonium (or heavy alkali) and make smart glass gall.Its chemical equation is the same.
The present invention has following advantage with respect to prior art: greatly reduce workshop cost, thereby obtain better economic benefit.
