Problems solved by technology

[0003] The production of polyaluminum chloride includes: metal aluminum method, aluminum hydroxide method, aluminum trioxide method, aluminum chloride method; no matter which method is used, solid or powder raw materials will be used, and solid and powder raw materials are used During the process, there are often incomplete reactions and deposits at the bottom of the reactor. Therefore, recycling the incompletely reacted raw materials can save production costs. At present, most recycling devices just dry the materials in the reactor through a filter press. Then put it directly into the reactor and use it again. The squeezed material in this method also has reaction residues, and recycling it will affect the purity of polyaluminum chloride.

Abstract

The invention discloses a recycling device for production waste residues of polymerized aluminum chloride. The recycling device mainly comprises a filter press, a filter cake stamping machine, a discharging machine, a washing kettle, a waste liquid tank and a slurry pump which are sequentially connected. The device is scientific and reasonable in structural design; the filter cake can be repeatedly cleaned, so that the production cost is reduced.

Description

technical field [0001] The invention relates to the field of polyaluminum chloride production, in particular to a recycling device for polyaluminum chloride production waste slag. Background technique [0002] Polyaluminum chloride is a water purification material, inorganic polymer coagulant, also referred to as polyaluminum, English abbreviation is PAC, the molecular weight produced due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions Larger, higher charge inorganic polymer water treatment agent. It can be divided into solid and liquid in form. The solid is divided into brown, beige, golden yellow and white according to the color, and the liquid can be colorless and transparent, slightly yellow, light yellow to yellowish brown, and polyaluminum chloride of different colors has different advantages in application and production technology. big difference. [0003] The production of polyaluminum chloride includes: metal aluminum method,...
