Self-cleaning immersion type electrochemical water treatment device and operation method thereof

Abstract

The invention discloses a self-cleaning immersion type electrochemical water treatment device. The device comprises a reaction chamber, ultrasonic vibrating rods, an automatic blow-down module, a control module and electrodes, wherein the electrodes comprise anode plates and cathode plates; a controller, a voltage meter, an ultrasonic generator and a constant-current output power supply are arranged in the control module, and the voltage meter, the ultrasonic generator and the constant-current output power supply are connected with the controller; the ultrasonic vibrating rods are connected with the ultrasonic generator and arranged between the anode plates and the cathode plates, and the voltage meter is used for monitoring voltage between the anode plates and the cathode plates; the automatic blow-down module is arranged at the bottom of the reaction chamber and connected with the controller; the constant-current output power supply is connected with the controller, the voltage meter, the ultrasonic generator and the electrode. The immersion type device is high in treatment efficiency, does not occupy additional space and has an automatic dirt clearing and discharging function, devices are not required to be taken out for dirt clearing, and the input cost and the later operation cost of the device are reduced.

Description

technical field [0001] The invention belongs to the technical field of electrochemical industrial circulating water treatment and sewage treatment, and in particular relates to a self-cleaning immersion electrochemical water treatment device and a self-cleaning method. Background technique [0002] Circulating water system is one of the essential energy media in metallurgical industry, petroleum industry and chemical industry. However, with the prolongation of the use time of the circulating cooling system, there will inevitably be problems of system sedimentation, equipment corrosion and microbial growth, which will cause damage to the heat exchange equipment and even affect the heat exchange efficiency. Electrochemical water treatment technology can remove calcium and magnesium scaling ions in the circulating water system from the system by electrochemical means, and at the same time produce a large amount of hypochlorite, oxygen free radicals, sulfurous acid free radicals...

AI Technical Summary

Problems solved by technology

However, the dirt accumulated on the cathode usually falls into the pool, causing blockage to the water pipes, and the scale removal method on the plate generally adopts the method of manual descaling, that is, the equipment is pulled out by manpower or machine for beating or pickling Descaling is time-consuming and labor-intensive
