Problems solved by technology

[0003] The two-step reaction system for polyaluminum chloride production is equipped with separation tanks, separation slag storage tanks, and flocculant preparation tanks. In these devices, the insolubles produced in the polymerization reaction are separated by coagulation, sedimentation, and sedimentation. Control and reduce the content of insolubles in the reaction solution to a certain extent, but through use, it is found that the content of insolubles is still high, and it has a negative impact on the yield and quality of polyaluminum chloride products

Abstract

The invention discloses a solid-liquid separation type two-step reaction system for production of polyaluminum chloride. The two-step reaction system comprises a conditioning tank, a conditioning tank transfer tank, a cooling tower, a separating tank, a separated slag storing tank, a flocculating agent preparing pot and a semi-finished product tank, wherein the conditioning tank is provided with a calcium aluminate feeding inlet and a first-step liquid feeding inlet; the conditioning tank is communicated with the conditioning tank transfer tank; the outlet of the cooling tower is communicated with the separating tank; the flocculating agent preparing pot is communicated with the separating tank; the upper part of the separating tank is communicated with the semi-finished product tank; and the lower part of the semi-finished product tank is communicated with the separated slag storing tank. The two-step reaction system is characterized by further comprising a cyclone separator arranged between the conditioning tank transfer tank and the cooling tower; the conditioning tank transfer tank is connected with the liquid inlet of the cyclone separator via a conditioning liquid delivery pump; and the overflow liquid outlet of the cyclone separator is connected with the liquid inlet of the cooling tower. The system reduces the content of insoluble substances in the manner of solid-liquid separation so as to improve the output and quality of a polyaluminum chloride product.
