An electrolysis preparation device for ozone

Abstract

The invention relates to an electrolysis preparation device for ozone. An anode catalyst membrane plate, a cathode catalyst membrane plate and a PEM membrane in an electrolysis electrode assembly alladopt elastic deformable materials. An electrolysis generator adjusting device is provided and includes a vertical shaft, an adjusting slide block, a supporting slide block, a fixing block and adjusting frames. Adjusting bars and a plurality of pull bars are disposed in each adjusting frame, and are movably hinged to the adjusting slide block and the supporting slide block on the vertical shaft. Aplurality of the adjusting frames are disposed at the periphery direction of the vertical shaft and encircle to form a cylindric shape. The left and right adjusting bars are pushed to move up and down, thus pushing each pull bar hinged with the adjusting bars in the corresponding adjusting frame so that the electrolysis electrode assembly tightly covering the cylindric shape formed by the plurality of adjusting frames is thereupon deformed elastically to a certain degree, and the ozone preparation speed is increased.

Description

technical field [0001] The invention relates to the technical field of ozone preparation by low-pressure electrolysis, in particular to an ozone electrolysis preparation device with a regulating device. Background technique [0002] Ozone is a light blue gas, which is a very strong oxidant. It inhibits the reproduction and growth of bacteria through oxidation, and leads to the death of bacteria. It is also a strong bactericide. Ozone can dissolve in water, and ozone water with a certain concentration of ozone also has a strong bactericidal effect. Ozone and ozone water can sterilize and disinfect food and drinking water. When disinfecting drinking water, in addition to killing bacteria in the water and further purifying impurities in the water, it can also increase the oxygen content in the water. Ozone and ozone water have a certain curative effect on various skin diseases caused by bacteria, bacterial inflammation, burns and other diseases. Ozone and ozone water also hav...

Problems solved by technology

[0004] In the prior art, the equipment for preparing ozone by electrolysis mainly has the following technical problems: (1), the amount of ozone prepared by the production equipment and the preparation rate are generally not adjustable, and the adaptability of the equipment to different disinfection environments and disinfection requirements is poor; (2) When preparing ozone by electrolysis, the anode electrolysis products are ozone and oxygen, and the cathode electrolysis products are hydrogen and water. What is needed for ozone disinfection is the ozone generated by the anode, but the anode is accompanied by oxygen. In the prior art, it is generally The oxygen is not treated, but directly mixed with ozone, which will affect the concentration of ozone and the solubility in water, reduce the amount of ozone dissolved in ozone water, and then affect the disinfection effect; the hydrogen produced by cathodic electrolysis Generally, it is directly discharged into the air, which not only wastes energy but also causes potential danger, because the accumulation of hydrogen will lead to an increase in local hydrogen concentration, and dangerous accidents such as deflagration may occur under suitable conditions; If there is water, the water will slowly increase the water level in the cathode water tank, and will also have an adverse effect on the normal operation of the electrolysis; (3), in the prior art, the treated pure water is added for electrolysis before the electrolysis work, However, with the current technology, the prepared pure water will inevitably contain a certain amount of impurities, and the use of real ultrapure water will cost a lot, resulting in a sharp increase in costs; On the other hand, due to the existence of various metal ions, scale will be generated on the cathode and anode plates, which intensifies the negative impact on the electrolysis efficiency; (4), in the prior art, the cathode and anode water tanks are generally used directly The electrolyzed water in the equipment is used to dissipate heat and cool down the equipment, but the cooling effect is not good, and ozone is a substance that is extremely sensitive to temperature. Too high a temperature will cause the ozone to decompose and disappear; (5), in the prior art, it is generally The concentration of ozone water is determined by follow-up measurement. This measurement has a certain hysteresis, which is not conducive to accurately determining the actual amount of ozone generated. Moreover, ozone is a substance that is relatively easy to decompose, which also increases the inaccuracy of the measurement. , which is not conducive to accurately considering the performance of an electrolytic ozone production equipment; (6). In the prior art, the cooling of the cathode and anode generally adopts a passive cooling method, mainly by means of the flow of electrolyzed water to the electrolysis of the cathode and anode water tanks. Passive cooling of water, this cooling method is not adjustable, and the cooling effect is not good; (7), after the electrolysis work stops, there will still be some ozone in the electrolysis components, if the remaining ozone is not removed in time , it will cause serious corrosion and oxidation to the electrode membrane plate in the electrolytic assembly and the water tank of the cathode and anode, which may shorten the service life and working efficiency of the electrolytic assembly and electrolytic equipment
