Full-automatic backwashing device for deionization loop

Abstract

The invention is applicable to the technical field of water cooling systems and provides a full-automatic backwashing device for a deionization loop. The deionizing device comprises a deionizing loopwith an electric ball valve II and a deionizing tank, wherein the deionization loop is connected to the cooling loop in parallel; the device further comprises a water tank and an electric ball valve I, wherein the water tank and the deionization loop are arranged in parallel to form a backwash circuit, the backwashing module is used for carrying out backwashing on the deionization loop; an electric ball valve I is arranged on the backwashing loop. The beneficial effects of the invention are that: the method is suitable for large-scale production; the deionization loop can be backwashed; risksof high conductivity alarm and the like caused by too small flow of a deionization loop are avoided; in addition, small bubbles in the deionization loop can be brought back into the water tank to be precipitated and then supplemented back to the cooling loop during backwashing, the dual functions of backwashing and system exhausting are achieved, the replacement period of the precision filter is effectively prolonged, human intervention and judgment are reduced, and the failure rate is lower.

Description

technical field [0001] The invention relates to the technical field of water cooling systems, in particular to a fully automatic backwashing device for a deionization circuit. Background technique [0002] In order to adapt to the use requirements of power electronic equipment under high voltage conditions and prevent leakage currents under high voltage conditions, the cooling medium must have extremely low conductivity. Therefore, the deionized water treatment circuit is connected in parallel on the main circulation cooling circuit. Part of the cooling medium with a preset flow rate flows through the ion exchanger to continuously purify the ions that may be precipitated in the pipeline, and then merges with the cooling medium of the main circulation loop before the main circulation pump. Through the continuous removal of ions in the cooling medium, the purpose of maintaining extremely low conductivity for a long time is achieved. [0003] However, in practical application...

Problems solved by technology

[0003] However, in practical applications, when the deionized water treatment circuit is blocked and its flow rate is reduced, it needs to be shut down and manually cleaned up. Therefore, the automatic backwashing device for the deionized circuit of the closed pure water cooling system is particularly important.
