　　Oxygen source, ozone generator manufacturer, ozone generator, ozone disinfection equipment

　　Ozone generator is a device used to produce ozone gas (O3). Ozone is prone to decomposition and cannot be stored, so it needs to be produced and used on-site (in special cases, short-term storage can be carried out). Therefore, any place where ozone can be used must use an ozone generator. Ozone generators are widely used in fields such as drinking water, wastewater, industrial oxidation, food processing and preservation, pharmaceutical synthesis, and space sterilization. The ozone gas generated by the ozone generator can be directly utilized or mixed with liquid through a mixing device to participate in the reaction. Obtaining methods

　　The use of high-pressure ionization (or chemical, photochemical reactions) to decompose and polymerize some oxygen in the air into ozone is a process of oxygen allotrope transformation; It can also be obtained using electrolysis method. The instability of ozone makes it difficult to store it in bottles, so it can only be produced on-site using an ozone generator and used as needed. The classification of ozone disinfection equipment for oxygen source ozone generator manufacturers is based on the way ozone is generated. There are three main types of ozone generators: high-voltage discharge, ultraviolet irradiation, and electrolysis.

　　circuit

　　The ozone generator circuit consists of transistors VT1 and VT2, inductor coils L1-13, pulse transformer T, current limiting resistor R1, charging capacitor C3, bidirectional trigger diode 5, etc., forming a push-pull oscillation circuit; The filtering inductor L0, rectifier diode VD1, and filtering capacitors C1 and C2 form a half wave rectification filtering circuit. Connect the power supply, AC 220V voltage is filtered by LO, rectified by VD1, and a voltage of about 280V is generated at both ends of C1 to supply the push-pull oscillation circuit. At the moment of startup, VT1 conducts. Due to the charging effect of C3, the bidirectional trigger diode VD5 is turned off. When the charging voltage at both ends of C3 rises to 32V, VD5 is triggered to conduct, causing VT2 to conduct. During the conduction period of VT2, C3 gradually discharges, causing VT2 to turn off. After VTl is turned on, the ozone disinfection equipment of the oxygen source ozone generator manufacturer generates positive feedback voltage on L1 and L2 under the action of the pulse transformer T. This voltage is applied to the bases of VTl and VT2 respectively, causing VTl and VT2 to alternate between conduction and cutoff (i.e. VT2 is cutoff when VTl is conductive; When VT2 is turned on, VTl is turned off, and the push-pull oscillation circuit oscillates. After the push-pull oscillation circuit works, a pulse high voltage is generated on the secondary winding L6 of the pulse transformer T, causing the ozone generator VG to operate and produce ozone.
