The key to realize the resource utilization and disposal of the high-salt organic waste liquid is to completely separate the organic matters and the salt in the high-salt organic waste liquid, and firstly, conditions are created to crystallize the salt in order to completely separate the organic matters and the salt in the high-salt organic waste liquid.

In the evaporation process of the thin-layer drying equipment, if the mother liquor is not uniformly distributed, the surface of the main equipment cannot be uniformly formed into a film, so that heat exchange is deteriorated, and energy consumption is wasted; if the liquid film is not uniform in thickness seriously, the equipment is difficult to evaporate. Therefore, in order to enable the solution to form a film on the surface of the main equipment uniformly and keep the solution consistent in the thickness direction, the working performance of the thin-layer dryer and the final recycling effect of the high-salt organic waste liquid are directly influenced.

The conventional spraying type liquid distributor can spray mother liquid into liquid drops or the liquid drops cover the outer surface under the ideal state, and the liquid drops are connected and accumulated to form a continuous and uniform liquid film to exchange heat with the thin-layer drying main body equipment; but in practice, the pressure and flow rate are difficult to control in the spraying process, whether the mother liquor is uniformly distributed on the outer surface of the main equipment cannot be determined, and the mother liquor is easy to carry liquid drops with small volume after evaporation and gasification, so that the serious problem of air suction and liquid carrying is caused; in addition, for a conventional spraying liquid distributor, when the organic matter content of the mother liquor added into the liquid distributor is high, sticky colloid is easily formed, so that the mother liquor is accumulated in a groove between main body devices, liquid distribution is uneven in use, the mother liquor accumulated in the groove is more and more sticky along with continuous extension of the operation time, and the drying dryer cannot continue to operate; for the lower submerged distributor, the mother liquor with high organic content is continuously evaporated under the action of high heat, the concentration of the organic matter is continuously increased, and the fluidity of the mother liquor is increasingly poor, so that the equipment cannot run.
