Device and method for ion exchange resin monitoring and sampling in operation

Abstract

The invention provides a device and method for ion exchange resin monitoring and sampling in operation. The method includes steps: sampling pipeline assembly, to be more specific, equally dividing a sampling pipe into n parts, and externally making the pipe; sampling pipeline seal test; resin sampling; sample subpackage; sample testing, wherein a teflon tape is adopted for hermetic winding of a seal port in the step of resin sampling. The device and the method have advantages of high sampling speed, freeness of influences on equipment operation, freeness of limitation on height of an ion exchanger under the normal pressure, accuracy in resin characteristic layer determination, simplicity in sampling process and freeness of high consumption of manpower and material resources.

Description

technical field [0001] The invention relates to the field of technical supervision of water treatment systems, in particular to a method for sampling resin in a vertical fixed-bed ion exchanger under operating conditions and a device used therefor. Background technique [0002] Ion exchange resin is usually filled in the vertical fixed bed ion exchanger, which is an important water-making filler in the water treatment system and plays an important role in providing stable purified water for the entire plant (unit). Ion exchange resins mainly exist in three states of operation, failure and scrap during use. Usually, it is determined whether the resin is invalid by monitoring the leakage degree of the ion to be removed, and it is determined whether the resin is scrapped by regularly analyzing the resin for scrap. When the resin fails, it can be restored to its exchange capacity through the regeneration process and put into use again; but if the resin is scrapped, it can only ...

AI Technical Summary

Problems solved by technology

Since the replacement time of the resin in operation has been precisely determined by the specification, but the failure and scrapping time of the resin cannot be pre-determined, this will inevitably make the old resin still have residual exchange capacity when the resin is regularly replaced. In this case Renewing all of the new ones will result in waste

Generally, the design replacement period of ion exchange resin in small closed water treatment systems is 2-3 years, and in actual production, all replacements are usually performed within one year. This waste is obviously huge.
