Production method and production system of high-purity polyaluminum sulfate chloride

Abstract

The invention discloses a production method and production system of high-purity polyaluminum sulfate chloride. The system comprises a preparation device, a reaction device, a post-treatment device, acollection container and a heat exchange device, wherein the heat exchange device is communicated with the outlet of the preparation device, the first inlet of the reaction device, the outlet of thereaction device and the inlet of the post-treatment device; a first raw material mixed liquid input through the outlet of the preparation device flow through the heat exchange device, and is used forexchanging heat with a reaction product input through the outlet of the reaction device; the heated first raw material mixed liquid is input into the reaction device through the first inlet of the reaction device; and the cooled reaction product is input into the post-treatment device through the inlet of the post-treatment device. The production system is simple and convenient in structure, and can be used for continuously and automatically preparing polyaluminum sulfate chloride; and the preparation method has high efficiency and low energy consumption, is energy-saving and environment-friendly since reaction heat, dilution heat and product heat are sufficiently utilized; and the prepared product has high purity and good quality, and accords with the national standard of GB15892-2009.

Description

technical field [0001] The invention relates to a production method of an inorganic high-efficiency water purifier, in particular to a production method of high-purity polyaluminum sulfide chloride, which can be used as a high-efficiency water purifier for domestic water, industrial water, industrial waste water, etc. Purification treatment and oil-water separation. Background technique [0002] Polyaluminum sulfate chloride PACS (polyalumnium sulfate chloride) is a composite modified polyaluminum chloride, and its general structure is [Al 4 (OH) 2n Cl 10-2n (SO 4 )] m , wherein, n=1~4, m=1~5. Polyaluminum sulfide can be used as a flocculant, mainly used for special water quality treatment of drinking water and water supply, such as removing iron, fluorine, cadmium, radioactive pollution, removing floating oil, etc. [0003] At present, when preparing composite polysulfide aluminum chloride, most of the cooked ore powder and ordinary calcium aluminate are used, and som...
