Low speed large capacity centrifuge in 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. Low speed large capacity centrifuge 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 approach, the mechanization degree is high, the cost is low. Characteristics of low speed large capacity centrifuge used salt mine is dissolved in the water of mining, the specific measures are: 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 borehole wall, pressure of high-pressure water from a well in salt bed, form a channel, dissolved salt, saturated brine by constitution, another well on, to produce. Low speed large capacity centrifuge learned that salt is in the storage tank, brine input brine pool after the purified, using steam heating, so that water continuously transpiration. Brine through transpiration is formed after the salt slurry semi salt half water, and then by the 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.
