Problems solved by technology

[0010] 1. Photochemical method: making O 3 The electric energy efficiency is very low, about 660kwh / kgO 3
[0011] 2. Electrochemical method: the power efficiency is not high, about 150kwh / kgO 3
[0031] The energy efficiency of manufacturing "HO" by this method is: energy consumption of 1kwh is only "gram" level, so it will not be used

Embodiment Construction

[0070] refer to figure 1The first embodiment of the present invention is composed of a cathode 2, an anode 3, and a bipolar membrane 4 located between the cathode and anode. The catholyte chamber 5 is formed between the bipolar membrane 4 and the cathode 2, and the anode is formed between the anode 3. The liquid chamber 6, the outer ends of the anode 2 and the cathode 3 are respectively connected with the positive and negative poles of the DC power supply. The cathode 2 and the anode 3 all adopt single-sided electrodes with a flat plate structure, and the cathode 2, the anode 3 and the bipolar membrane 4 are parallel to each other, and the catholyte 7 and the anolyte 8 are all water, and the liquid The flow mode is in parallel, which can reduce the pressure required for liquid flow, thereby achieving the goals of cost reduction, simple structure, and energy saving.

Abstract

The invention relates to a bipolar membrane dual-liquid flow type hydroxyl radical generator, belonging to the technical field of electrochemistry electrolytic oxidation. The bipolar membrane dual-liquid flow type hydroxyl radical generator is composed of a cathode, an anode and a bipolar membrane located between the cathode and the anode. A cathode liquid chamber is formed between the bipolar membrane and the cathode; an anode liquid chamber is formed between the bipolar membrane and the anode; both the cathode and the anode adopt a single face electrode with a panel structure; and the cathode, the anode and the bipolar membrane are parallel to each other. The invention ensures that high-concentration hydroxyl radical strong oxidant solution can be generated by very low voltage and very high electricity efficiency, the effects of water sterilization, disinfection, decoloration, deodorization, and the like are superior to that of ozone, chlorine and other oxidants, has no toxicity, residue and secondary pollution. The invention has a plurality of innovations that bipolar membrane energy-saving dissociation molecules are inserted between electrolytic cells to supply OH to produce .HO, lead-free tin oxide semiconductor electrode is supplied for a cavity (h+) without lead to pollute water body, and a dual-liquid stream structure is used so that the concentration of .HO is never saturated.

Description

(1) Technical field: [0001] The invention relates to a hydroxyl radical generator, in particular to a bipolar membrane double-flow type hydroxyl radical generator, which belongs to the technical field of electrochemical electrolytic oxidation. (two) background technology: [0002] People cannot do without water in production and life, and water is the most important factor affecting people's survival and development. However, with the progress of society and the development of economy, water resources are increasingly polluted and gradually destroyed, and fresh water resources are very scarce in our country. Therefore, it is urgent to increase the utilization efficiency of water resources by increasing revenue, reducing expenditure and controlling pollution. In this way, not only should the fresh water resources be protected, multiple water cycles and zero discharge should be implemented, but also disinfection and purification should be carried out before the water is used t...
