On-line resuscitation device and method for iron poisoning of cation exchange resin

Abstract

The invention relates to the technical field of ion exchange resin on-line cleaning, and in particular to an on-line resuscitation device and method for iron poisoning of cation exchange resin. The on-line resuscitation device is provided with an ion exchanger, wherein a water inlet pipe is arranged on the upper side of the ion exchanger, a water outlet pipe is arranged below the ion exchanger, one end of the water outlet pipe is connected with the ion exchanger, the other end of the water outlet pipe is connected with a soft water tank, an outlet valve is arranged on the water outlet pipe, and the soft water tank is connected with an external water supply system; the on-line resuscitation device is characterized in that the ion exchanger is provided with an online cleaning mechanism and a backwashing mechanism. The on-line resuscitation device and method disclosed by the invention has the advantages of simple structure, short resuscitation time, thorough resuscitation effect, and low waste of resources.

Description

technical field [0001] The invention relates to the technical field of on-line cleaning of ion exchange resins, in particular to an on-line recovery device and recovery method for cation exchange resin iron poisoning with simple structure, short recovery time, thorough recovery effect and low waste of resources. Background technique [0002] As we all know, cation exchange resins are widely used in water treatment equipment for removing calcium and magnesium ions in water such as demineralized water in power plant boilers, softened water in industrial boilers, and pure water production. During the use of the device, it often comes into contact with iron-containing groundwater or iron ions in the incoming water due to pipeline corrosion, resulting in the contamination of the cation exchange resin by iron ions, commonly known as iron poisoning. Although the content of iron ions in the water is very small, as the operation continues year after year, more and more iron ions will...

Problems solved by technology

[0006] The traditional regeneration method has the following problems: 1. The regeneration steps are complicated; 2. The utilization rate of the regenerant is low, and the waste of the agent is serious; 3. The regeneration water consumption is large, not only requires a lot of water costs, but also requires a lot of money for the regeneration wastewater treatment. Cost; 4. It usually takes a long time to complete a regeneration, and the efficiency of regeneration time is low
