Abstract

The invention discloses a novel ion exchanging system based on multi-way valves. The novel ion exchanging system comprises 2-4 multi-way valves and 2-3 ion exchanging columns, wherein the adsorption, regeneration and elution of the ion exchanging columns are switched through rotary operation of the multi-way valves. By virtue of the system, the defects of a traditional interval type fixed bed that the pipeline is complicated, more valves are arranged, the resin utilization rate is low and the like are overcome; and meanwhile, the function of continuously adsorbing of the novel ion exchanging system online is realized. On the basis of continuous work of the system and the maximum utilization of resin, the low-cost, low-fault, low-energy-consumption and automatic operation is realized.

Description

technical field [0001] The invention belongs to the field of ion exchange, in particular to a novel ion exchange system based on a multi-way valve. Background technique [0002] As a very common chemical separation technology and chemical operation unit, ion exchange has the characteristics of strong separation selectivity and high concentration multiple, and is widely used in many fields of chemical industry, especially the separation, enrichment and purification of chemical substances in the production process. And various industrial water purification and recovery. [0003] The ion exchange equipment that has appeared so far is divided into gap type, periodic type, and continuous type according to the operation mode; according to the two-phase contact mode, it is divided into fixed bed, moving bed, fluidized bed, etc. Fixed bed is currently the most widely used ion exchange equipment. Although it has the advantages of simple structure and convenient operation and managem...
