Automatic circulating water electrolysis descaling device and method

Abstract

The invention relates to an automatic circulating water electrolysis descaling device and method. The device comprises a reaction box body, a water inlet and control valve, a water outlet and control valve, a slag discharging outlet and control valve, a first scraper, a filtering packing layer, a back washing structure, a box body top cover and a support. The device is further provided with a cathode and assembly, an anode and assembly and a washing structure. The cathode and assembly and the anode and assembly are concentrically installed inside the reaction box body. A washing structure pipeline is fixed to the inner wall of the reaction box body. The box body top cover on the upper portion of the reaction box body is of a sphere crown shape, and the bottom of a cone shape. A fixed plate with small uniform holes and sliding rails is arranged at the connecting position of the lower end of a cylindrical body of the reaction box body and the cone-shaped bottom edge. By the adoption of net tube-shaped electrodes, the scale removing method with automatic mechanical scale scrapping and washing being conducted at the same time is adopted to be combined with the filtering packing layer, so that scale removing is thorough, yielding water is made cleaner, and the automatic circulating water electrolysis descaling device and method are suitable for scale removing and corrosion prevention of circulating water.

Description

technical field [0001] The invention relates to a circulating water treatment technology in the field of environmental protection, in particular to a circulating water electrolysis automatic descaling device and method. Background technique [0002] At present, in the existing circulating water electrochemical descaling technology, the descaling methods include manual descaling and mechanical automatic descaling. [0003] Manual descaling requires regular opening of the reaction chamber of the device for manual descaling, which wastes human resources and time, and the processing efficiency is low. [0004] Mechanical automatic descaling usually uses a mechanical scraper to scrape the scale on the flat plate in a straight line. This structure is not conducive to water flow control, and cannot ensure that the water flow passes through the reaction zone evenly, so as to fully treat it; at the same time, it is easy to produce long-term The hard scale formed by extrusion is diff...

[0003] Manual descaling requires regular opening of the reaction chamber of the device, manual descaling, waste of human resources and time, and low processing efficiency

[0004] Mechanical automatic descaling usually uses a mechanical scraper to scrape the scale on the flat plate in a straight line. This structure is not conducive to water flow control, and cannot ensure that the water flow passes through the reaction zone evenly, so as to fully treat it; at the same time, it is easy to produce long-term The hard scale formed by extrusion is difficult to remove. If things go on like this, it will seriously affect the efficiency of the device and increase energy consumption; in addition, the effluent water of the device is likely to be accompanied by loose and fine scale, which enters the pipeline with the water flow, deposits in it, and is easy to block and enter the heat exchange. Deposits in it will affect the heat transfer efficiency
