Description
Technical Field
The invention relates to a monitoring circuit of a high-voltage discharge type ozone generator and an ultraviolet irradiation type ozone generator.
Background
The ozone generator is an electrical device for producing ozone gas (molecular formula: O3). Ozone, due to its chemical nature, is easily decomposed and cannot be stored, generally by means of on-site preparation (storage for a short time only in very specific cases), and therefore ozone generators are widely used for extracting ozone gas for drinking water, sewage, industrial oxidation, food processing and preservation, pharmaceutical synthesis, space sterilization and other fields, such as: the sterilization aspect can rapidly kill various bacteria and viruses, and has no secondary pollution; the detoxification aspect can effectively remove the residual pesticide in the food; in the aspect of deodorization, various odors such as musty odor, smoke odor, oil smoke odor, water stain, garbage and the like can be removed; the oxygen content of air and water can be improved in the aspect of oxygenation; in the aspect of health care, the air is purified, and the metabolism of a human body is promoted; the fresh-keeping aspect can be used for keeping fruits, vegetables and eggs fresh.
The ozone generator is mainly divided into three types according to the ozone generation mode: the first is a high-voltage discharge type, the second is an ultraviolet irradiation type, and the third is an electrolysis type. The working principle is that partial oxygen in the air is decomposed and polymerized into ozone by means of high-pressure ionization, photochemical or chemical reaction, and the conversion process is an allotropic conversion process of oxygen. The chemical formula is as follows:
3O2＝＝＝＝2O3
the high-voltage discharge type ozone generator is used for producing a high-voltage corona electric field by using high-voltage current with a certain frequency, so that oxygen molecules in or around the electric field generate electrochemical reaction, thereby producing ozone. The mode is generally driven by a medium-high frequency power supply, has the advantages of large ozone yield (a single machine can reach 1Kg/h), stable work, long service life and the like, and has the most mature technology and the most extensive use.
The ultraviolet ozone generator generates ozone by irradiating oxygen molecules with ultraviolet rays having a specific wavelength (185mm) to decompose the oxygen molecules. The generator has a narrow application range due to the large size of the ultraviolet lamp, the low ozone output and the short service life.
The electrolytic generator adopts a novel PEM membrane to electrolyze deionized water by using positive and negative poles of a low-voltage direct current conducted solid-state membrane electrode, water is separated into oxyhydrogen molecules in a proton exchange mode on a special anode solution interface, hydrogen is directly discharged from a cathode solution interface, and the oxygen molecules obtain energy on the anode interface due to the excitation of electrons generated by high-density current and are polymerized into ozone molecules. This approach is costly and is currently used less often.
Ozone excitation terminals of high-voltage discharge type ozone generators are easily damaged. The common types of the ceramic tube, the quartz tube, the ceramic plate, the ceramic tube, the glass tube, the enamel tube and the like have the defects of poor mechanical strength and easy damage caused by temperature stress or electric breakdown according to the division of dielectric materials. The drive transistor and transformer coil of the ozone generator are also operated at high temperature and high pressure and are easy to damage. After the ozone generator is damaged due to faults, if the ozone generator is not timely treated, the using function is slightly influenced, and serious consequences such as fire disasters and the like are generated due to continuous high-temperature discharge and the like. Therefore, the detection of the working state of the generator is of great significance.
In addition, the ozone generator works in an environment needing sterilization, the generated high-concentration ozone is harmful to a human body, and the high-voltage discharge type generator produces NOX gas which has carcinogenic effect on the human body, so that workers are difficult to stay on the site to monitor the working condition of the generator in real time, and a detection circuit is inevitably used for generating a high-reliability real-time monitoring signal.
Currently, the known ozone generator circuit is a self-excited oscillation booster circuit, as shown in fig. 1, which induces an ac voltage from a winding W5, and drives a light emitting diode VL to illuminate after being rectified by VD6 to indicate an operating state.
The disadvantage of this circuit is that the transformer of the circuit is particularly complex in construction and, in addition, the stability of the circuit is poor and VL is easily burnt out by interference from the high voltage circuit.
