Automatic decapping centrifuge to understand well and rock salt production mainly divided into brine and salt two links. The ore type is not the same use not the same brine method. Get natural brine solution with Bailing method, gas lift method, brine, pumping of deep well submersible pump, flowing brine and other methods. Automatic decapping centrifuge found in rock salt mining area mostly used drilling solution mining method, some selection of single well convection, some selection Shuangjing hydraulic fracturing method.
1 convection method
This is the current domestic and international mining of rock salt deposit contrast throughout the selection method, the mechanization degree is high, the cost is low. Automatic decapping centrifuge understanding it to use salt mine is dissolved in water features of mining, the specific measures are: playing a well casing to salt, two layer, outer casing oil l cement is good well, from which a layer of tube into the water, the dissolved salt, by another pipe to brine pumped.
2 fracturing method
This method is called two wells, on the ground of human casing, the well pipe is fixedly sealed and well wall, pressure of high-pressure water from a well in salt bed, constitute the channel, dissolved salt, brine composition plump, by another well on, to produce. Salt is in the storage tank, brine input brine pool after purification, using steam heating, so that water continuously transpiration. Automatic decapping centrifuge to understand salt slurry brine through transpiration after half salt water into half, then by a centrifuge dewatering, input boiling bed boring namely for product salt; if the brine containing Glauber's salt is more, can choose frozen mother liquor or thermal method proposed mirabilite; CO production of salt and nitre technology in Jiangxi salt mine into the Swiss Sulzer Ltd, representative leading the. If the brine containing gypsum is more, put forward to ensure the quality of salt gypsum.
