Abstract
The invention provides a production method of an ore brine crystal salt. In the method, ore brine is used as raw brine, wind and sunlight are used as energy sources, and a shoal pool is used as a crystallization pool. The production method is characterized by comprising the following steps: after exploiting the ore brine, firstly passing the exploited ore brine through a pipeline and then weighing with a pump station, respectively storing the weighed ore brine crystallization salt in a brine hoarding table, pouring to a crystallization pool from the brine hoarding table, and evaporating and crystallizing through the wind and sunlight in the crystallization pool; and controlling the concentration and depth of the brine, properly adding or replacing novel brine, mastering the depth and market demand of the crystal salt, discharging the brine and recovering the salt timely, and recycling the old brine. According to the invention, energy consumption is low, 0.18 ton of coal and 50-60kw.h of electricity are consumed for producing every ton of ore salt, and the electricity consumption of every ton of salt is about 5kw.h in the invention; large land area is saved and accounts for 1/20 of that of sea salt; the method is environmentally-friendly, and zero emission is basically achieved; and the produced ore brine crystal salt has high quality, meets a GB/T5 462-2003 prior industrial salt standard, has extremely less impurity ions and large crystalline particles, and is especially suitable for a chlor-alkali industry.
Description
Technical field
The present invention relates to a kind of salt extraction process, the production method of particularly a kind of ore deposit halogen xln salt
Background technology
At present, salt is classified with raw material sources, can be divided into sea salt, lake salt, well mine salt; Divide by production method, can be divided into vacuum salt, evaporate brine day.Sea salt, lake salt are to evaporate brine day, are crystalline particle salt; Well mine salt is used ore deposit halogen vacuum salt exactly, be powdery salt, be that drilling well pours into fresh water to rock salt, make the salt generation soluble in water ore deposit halogen in the rock salt, again ore deposit halogen is extruded with the salt manufacturing of vacuum salt production method, sea salt is that seawater is received tide, by Exposure to Sunlight water evaporates is reached certain concentration, and salt is crystallized out.Rock salt energy consumption height, the sea salt floor space is big.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of new salt extraction process, not only cut down the consumption of energy but also saved the big area soil, improved the output and the quality of salt simultaneously.
The technical scheme that the present invention deals with problems is: the production method of a kind of ore deposit halogen xln salt, with ore deposit halogen is former halogen, to expose to the weather is the energy, with the pond, beach is crystallizing pond, it is characterized in that: ore deposit halogen crystalline particle salt, ore deposit halogen exploitation back is divided storage village halogen platform through pipeline by pumping plant metering back earlier, pours into crystallizing pond by collecing the halogen platform again, in crystallizing pond by the evaporative crystallization of exposing to the weather; Halogen is added or more renew in good time to the concentration of bittern, the degree of depth in the crystallization control pond, grasps the degree of depth and the market requirement of crystal salt and in time arrange halogen receipts salt, and old halogen recycles.
The control of each workshop section's saltwater brine concentration, the concentration of ore deposit halogen is about 24 ° of Be ', village halogen platform is 25 ° of saturated halogen of Be ' to the concentration of the saltwater brine that crystallizing pond pours into, the first crystallizing pond saltwater brine concentration is that 25.5 ° of Be ', second crystallizing pond are that 26 ° of Be ', the 3rd crystallizing pond are that 26.5 ° of Be ', the 4th crystallizing pond are 27.3 ° of Be ', and the crystallizing pond halogen concentration of more changing gear is 27.3 ° of Be '.
The height of crystallizing pond liquid level is controlled at about 25-30cm.
Crystallizing pond is made as one group of several series connection, and best quartet, its end height are and gradually fall formula, and with halogen, the import and export of halogen are the diagonal angle setting with the control of lock gate hole.
Crystallizing pond, village halogen platform all adopt mould cover with mat rainproof, non-woven geotextile protects low bank between fields, mould the side of deploying troops on garrison duty oozes, moulds the cloth bank protection, is provided with the light ditch of row pond week.
Old halogen is handled, and old halogen is left concentratedly in the winter time in the 4th crystallizing pond (or storage halogen pool), and after winter low temperature (below 5 ℃) was freezing, sodium chloride crystal was separated out, and bittern recycles as new halogen, and saltcake is sent outside the pond with pipeline.
Old halogen is handled, and old halogen is concentrated anhydrous nitre of the freezing extraction in pipe-line transportation chemical plant and liquid salt through returning the halogen ditch to storing up the halogen pool.
Old halogen is handled, and old halogen is concentrated to storing up the halogen pool through time halogen ditch, and old halogen blowback is collectd the halogen platform and add an amount of calcium chloride in the halogen platform of village and uses except that making new halogen behind the nitre.
Crystal salt is collected and is adopted the pipeline salt harvester, and stays the dark 5cm of dead quarrel salt at the bottom of the pond.
Useful effect of the present invention is, same output, and energy consumption is low, 0.18 ton in rock salt ton salt consumption coal, power consumption 50-60kwh, and about ton salt power consumption 5kwh of the present invention; The saving land area is big, is 1/20 of sea salt; Environmental, realize zero release substantially; Functionality, quality and appealing design, product meet GB/T5462-2003 top grade Industrial Salt standard, and foreign ion is few, and crystalline particle is big, is specially adapted to chlorine industry salt.
