Embodiment Construction

[0020] A production method of bittern crystalline salt, using bittern as raw bittern, wind and sun as energy source, beach pond as crystallization pool, bittern crystalline salt, after the bittern is mined, the laid pipeline passes through the pumping station After metering, divide and store brine platform 3, pour into crystallization tank 6,9 (9-1,9-2,9-3,9-4), 11,14 by storage brine platform 3 again, pass wind in crystallization tank Blow the sun to evaporate and crystallize; control the concentration and depth of brine in the crystallization pool, add or replace new brine in a timely manner, grasp the depth of crystallized salt and market demand, discharge brine and collect salt in time, and recycle old brine.

[0021] The plane setting of the field area is divided into several units, and each unit is equipped with 8 combined plots, which are divided into four rows and two columns. There are four brine storage ponds 2 between the two columns. There are drainage ditches 7 an...

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 [0001] The present invention relates to a method for producing salt, in particular to a method for producing bittern crystalline salt Background technique [0002] At present, salt can be classified into sea salt, lake salt, and mine salt according to the source of raw materials; according to the production method, it can be divided into vacuum evaporation salt and solar salt. Sea salt and lake salt are sun-dried salt, which is crystalline granular salt; well mine salt is produced by vacuum evaporation of mineral brine. Mineral bittern, and then press out the bittern and use the vacuum salt method to make salt. Sea salt is to absorb the tide of sea water, and evaporate the water to a certain concentration through the sun, so that the salt crystallizes out. Mineral salt consumes a lot of energy, and sea salt occupies a large area. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a new salt pr...
