Silicon carbide ceramic tubular membrane alkali liquor purification and recovery integrated equipment

Abstract

The invention relates to the technical field of purification equipment, and discloses silicon carbide ceramic tubular membrane alkali liquor purification and recovery integrated equipment which comprises a box body, a first feeding box and a second feeding box are fixedly connected to one side of the top of the box body, discharging frames are fixedly connected to the bottoms of the first feeding box and the second feeding box, and openings in the bottoms of the discharging frames communicate with the interior of the box body; by means of the discharging frame and the inclined guide plate, waste liquid needing to be purified can be evenly mixed with coagulant aids or chemicals, the neutralization reaction can be continuously carried out, and the efficiency of the neutralization reaction is improved; and large sundries, solids generated by neutralization and purified liquid can be separately discharged through the first discharging channel, the second discharging channel and the fishing assembly, and the operation is performed through the same equipment, so that the subsequent classified utilization is facilitated while the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of purification equipment, in particular to an integrated equipment for purification and recovery of caustic soda with a silicon carbide ceramic tubular membrane. Background technique [0002] Alkali is a mixture of sodium carbonate and baking soda. Baking soda is a product obtained by absorbing carbon dioxide from a solution or crystal of soda ash. In cleaning equipment, it is often necessary to use cleaning fluid to clean the workpiece. There are various cleaning fluids, lye It is one of them, which can clean some workpieces such as filters. [0003] The Chinese utility model patent with the patent publication number CN215886610U discloses an integrated device for purifying and recycling silicon carbide ceramic tubular membrane lye, including a tank body, a feeding port is opened on one side of the surface of the tank body, and the feeding port passes through a hinge along one side of the edge A tank cove...
