Powder resin desorption regeneration reactor

Abstract

A regenerating reactor for desorbing a powdery resin, comprising a reactor (1), a resin separator (5), a desorption liquid tank (15), and a regenerated resin delivery system; the resin separator (5) has one end thereof connected to a discharging pipe for the desorption liquid (11), and the other end of the discharging pipe for the desorption liquid (11) is connected to a suction port of a water ejector (13) of a circulating pipe of the desorption liquid tank which is mounted on the circulating pipe (12) of the desorption liquid tank; an upper outlet of the circulating pipe (12) of the desorption liquid tank is in communication with the desorption liquid tank (15), and a lower outlet thereof is in communication with the desorption liquid tank (15) via a circulating pump (14) for the desorption liquid tank; the regenerated resin delivery system comprises a fully mixed resin reactor (10), a circulating pipe (7) of the fully mixed resin reactor, a water ejector (8) of the circulating pipe of the fully mixed resin reactor and a circulating pump (9) for the fully mixed resin reactor. The reactor can complement any reactor directed to such resins, make full use of the advantages of such resins, and achieve the operations of continuous separation and regeneration of resin in the resin reaction device.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, and more specifically relates to a powder resin desorption regeneration reactor. Background technique [0002] In the advanced treatment of feed water, various types of wastewater and biochemical tail water, new powder resin treatment processes and equipment have been gradually used. Powder resin is a solid acrylic polymer material with an average particle size of 75-200μm, which contains rich pore structure and ionic groups, and has dual functions of electrochemical adsorption and ion exchange; the new powder resin has small particle size, It has the characteristics of large specific surface area and high reaction kinetic efficiency; however, due to the small particle size and relative density of powder resin or magnetic powder resin, when using traditional fixed bed or suspension bed, the resistance of the resin bed is large, and the resin It is easy to be compacted and broken, and the...

AI Technical Summary

Problems solved by technology

However, due to the small particles and density of powder resin, it is difficult to completely separate the liquid from the resin in a short period of time by means of sedimentation. At the same time, due to the low strength of the resin, it cannot withstand obvious mechanical forces (such as various types of pumping) , the resin must be transported to each working unit by means of hydraulic transport; in order to effectively transport the resin, separate the resin from various liquids efficiently, and complete the regeneration and transport process of the resin, it is necessary to develop a new type of reactor to improve the above problems
