Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water treatment equipment, and particularly relates to a circulating water treatment device. Background Art
[0002] Both cooling towers and heat exchangers need to treat circulating water through a circulating water treatment device. The circulating water treatment device of the prior art includes an electrolysis chamber, in which an anode and a cathode are arranged. The anode and the cathode are respectively connected to the positive and negative electrodes of a DC pulse power supply, and a mixed bactericide needs to be regularly added into the electrolysis chamber. The circulating water treatment device of the prior art sterilizes and algae-removes circulating water through the principle of electrochemical oxidation. Clostridium spores and Cryptosporidium-like in circulating water have strong tolerance to chlorine and other bactericides. By adding an electrolyte that can generate a mixed oxidant, a series of oxidizing substances are generated during the electrolysis process of this mixed oxidant, such as chlorine, chlorine dioxide, hydrogen peroxide, ozone and other active free radicals, showing better bactericidal performance than chlorine.
[0003] The circulating water treatment device of the prior art has the following disadvantages: 1. High cost and large volume. When the current density of the electrolytic cell is 5 mA / cm², the residence time needs to be more than 5 minutes for cells to completely lose their activity and stop growing and reproducing; 2. It is necessary to regularly add a mixed bactericide, and the use and maintenance costs are relatively high. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a circulating water treatment device with a simple structure, low maintenance cost and capable of efficiently treating circulating water.
[0005] To solve the above technical problem, a circulating water treatment device provided by the utility model includes a tank body. An outlet and a catalytic material input port are opened at the top of the tank body. A titanium dioxide catalytic filter bag is arranged in the tank body. A quartz container is arranged in the titanium dioxide catalytic filter bag, and a closed space is formed in the quartz container. A filter bag port is arranged at the bottom of the titanium dioxide catalytic filter bag, and the filter bag port is connected to a water injector arranged outside the tank body through a pipeline. The gas inlet of the water injector is connected to the top of the quartz container through a pipeline. A ultraviolet lamp and a gas pipe are arranged in the quartz container. One end of the gas pipe is located at the bottom of the inner cavity of the quartz container, and the other end of the gas pipe extends out of the quartz container and sequentially passes through the titanium dioxide catalytic filter bag and the tank body.
[0006] Further preferably, the water outlet is connected to the electrolysis chamber of the electrochemical oxidation device through a pipeline. An outlet for liquid is provided on the electrolysis chamber. An anode and a cathode are arranged in the electrolysis chamber, and the anode and the cathode are respectively connected to the positive and negative electrodes of a DC pulse power supply. The circulating water flowing out from the water outlet enters the electrolysis chamber, where the chloride ions in the circulating water are oxidized, releasing electrons, providing electrons to the cathode to generate oxygen, hydrogen ions and chlorine gas, forming a strong alkaline environment to achieve the scale removal effect. A strong acidic environment is formed on the surface of the anode. At the same time, strong oxidants such as ozone and hydroxyl radicals are used for sterilization and algae removal, completely solving the problems of bacterial drug resistance and the growth of slime.
[0007] Further preferably, a nickel titanium oxide coating is provided on the surfaces of the anode and the cathode to ensure that the electrodes are not corroded and the impurities in the water do not damage the electrodes.
[0008] The beneficial effects of the present utility model are as follows: During operation, air enters the quartz container through the air pipe, and the ultraviolet lamp irradiates the air in the quartz container to generate ozone. The ozone enters the water injector through the pipeline from the gas inlet. The circulating water enters from the pressure water inlet of the water injector and is mixed with the ozone to form a mixed liquid. The mixed liquid flows out from the mixed liquid outlet of the water injector and then enters the titanium dioxide catalytic filter bag. The ultraviolet lamp irradiates the mixed liquid in the titanium dioxide catalytic filter bag through the quartz container. The catalytic material is put into the tank body from the catalytic material input port to form an O3-UV photocatalytic oxidation synergistic effect and generate hydroxyl radicals, thereby achieving the effect of efficient and rapid sterilization. The mixed liquid then passes through the pores of the titanium dioxide catalytic filter bag and enters the tank body. Finally, the treated mixed liquid flows out from the water outlet of the tank body. Through the O3-UV photocatalytic oxidation process, the organic pollutants in the water can be completely mineralized without generating any secondary pollution, and the dissolved oxygen content in the water is increased, while the trace elements are retained. The circulating water treatment device of the present novel is simple and compact in structure, with low maintenance costs and no secondary pollution during use. BRIEF DESCRIPTION OF THE DRAWINGS
