In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an industry waste salt purification equipment, includes purification filter, three-way valve, heat exchanger, crystallizer, abandonment jar, circulating pump, heater, the filter include waste salt liquid entry, left card, filtration membrane, right card, refined salt water export, the crude salt water export, filtration membrane be the tubular membrane, install between left card and right card, waste salt liquid entry and refined salt water export are located the filter both ends respectively, the crude salt water export be located the filter side, and keep away from waste salt liquid entry, the heat exchanger be the riser heat exchanger, be equipped with hot refined salt water import, cold refined salt water export, cold waste salt entry, hot waste salt export, refined salt water export passes through the pipe connection with hot refined salt water import, install the circulating pump on the pipeline, cold refined salt water export is connected with the crystallizer, hot waste salt export pass through the pipe connection with waste salt liquid entry, the pipeline is provided with a heater.
Further, the crude brine outlet is connected with the inlet of a three-way valve.
Furthermore, an outlet at one end of the three-way valve is connected with the waste salt solution inlet, and an outlet at the other end of the three-way valve is connected with the waste tank.
Furthermore, a distribution cavity is formed between the left flower plate and the shell of the filter 1.
Furthermore, a liquid collecting cavity is formed between the right flower plate and the filter shell.
Furthermore, the joint of the filtering membrane and the left pattern plate is a blind end, and the joint of the filtering membrane and the right pattern plate is an open end.
The utility model discloses an industry waste salt purification equipment adopts cross-flow filtration membrane equipment to get rid of the smoke and dust impurity in the waste salt solution earlier, then will refine salt solution and waste salt solution behind the heat exchange, waste salt solution temperature risees, waste salt solubility increases, get into the heater and continue to go into the filter behind the rising temperature, impurity such as insoluble silicate in the waste salt solution is intercepted by filtration membrane, waste salt solution gets into inside being refined of filtration membrane, salt solution after the refining gets into the crystallizer after the heat exchanger heat transfer cooling, refined salt solution temperature reduces the back, salt solubility reduces and separates out, through having practiced thrift the energy to refined salt solution heat transfer, make waste salt solution temperature rise, the heat of heater has been practiced thrift. The filter is in a cross flow filtration mode, impurities intercepted on the surface of the filter membrane can be taken away by salt liquid, the filter membrane is prevented from being polluted, and a self-cleaning effect is achieved.
