Antiscale descaling sterilizing algae-removing device for high-temperature cooling water in metallurgy system

The utility model relates to a scale preventing and removing sterilizing algae removing device for high-temperature cooling water in the metallurgy system, which comprises a straight-way type water pipe (1) and an electricity controlled device in an electricity controlled cabinet (11) is connected with electrodes (7) through a high-frequency output wire (3). The straight-way type water pipe (1) is connected with an n-shaped communicating pipe (5); both ends of the n-shaped communicating pipe (5) are provided with connecting pipes (2) which are communicated with the straight-way type water pipe (1); the electrodes (7) are arranged on the right angle turning point of the n-shaped communicating pipe (5). The utility model overcomes the disadvantage that the existing scale preventing and removing algae removing device can cause environment pollution and can not adapt to changeable working environment and external condition, and the device can not keep good working condition. The device has the functions of memory and automatic effect restoration; the utility model has the advantages that the efficiency of preventing and removing scale can be chronically and stably kept; meanwhile, the acting chance and time of water and working electrodes can be increased.
