Problems solved by technology

[0003] Moreover, the composition of coking wastewater is complex, especially the presence of impurities and organic matter. In order not to affect the purity and evaporation effect of the salt separation products sodium chloride and sodium sulfate, it is necessary to discharge the mother liquor all the time. If the discharged mother liquor carries more products after entering Stage treatment will reduce the overall recovery rate of the product, resulting in excessive salt content in the latter stage, and subsequent treatment costs will be higher

Abstract

The invention belongs to the technical field of coal coking wastewater application, and particularly discloses an efficient solid-liquid separation device. The device comprises a circular barrel, a conical discharging shell, a solid outlet, a feeding opening, a guide cylinder, a plurality of vertical partition plates, overflow teeth, a hopper, a solid settling pipe, an overflow opening, a liquid delivery opening and the like. The efficient solid-liquid separation device has the beneficial effects that the design structure is reasonable, high-efficiency separation of a solid-liquid mixture is realized, the solid-liquid ratio of the solid-liquid mixture at an outlet is greatly improved, when impurities influencing the product purity in a system are enriched, mother liquor can be effectively discharged, the mother liquor is prevented from carrying more products to enter a later stage for treatment, the recovery rate of the product is improved, and the treatment cost of the carnallite is reduced.

Description

technical field [0001] The invention belongs to the technical field of coal coking wastewater application, and in particular relates to a high-efficiency solid-liquid separation device, which is suitable for supporting the coking wastewater evaporation crystallization and salt separation system. Background technique [0002] Evaporation crystallization is a common unit in the chemical industry. It is used for the separation and purification of liquids, and crystallizes the dissolved solids in the liquid. The liquid ratio requirement is high, which requires a high-efficiency solid-liquid separation device to increase the solid-liquid ratio of the solid-liquid mixture discharged from the evaporation crystallization system. [0003] Moreover, the composition of coking wastewater is complex, especially the presence of impurities and organic matter. In order not to affect the purity and evaporation effect of the salt separation products sodium chloride and sodium sulfate, it is n...
