Description
Technical field
The utility model relates to a kind of closed-loop control system, and particularly a kind of closed-loop control system of ozone generator belongs to the technical field of ozone generator.
Background technology
More and more with the ozone sterilization sterilization in fields such as tap water processing, chemical industry oxidation, wastewater treatment, pharmacy, food elder generations, the ozone demand is also increasing, how to control and regulate the ozone output of ozone generator, and the good ozone of rational Application is particularly important.Ozone output is the product of airshed and ozone concentration, can accurately control airshed and ozone concentration in the operational process of ozone generator well, and keeps the constant of two parameters, namely reaches the constant of ozone output.Ozone generator is to regulate by artificial and automanual method mostly at present, particularly in external condition (air pressure, cooling, temperature, source of the gas dew point etc.) when changing, more than two parameters can change thereupon, need manually carry out process tracking, and timely adjustment, operate cumbersome and can not accurately control, brought difficulty for the good ozone of user's rig-site utilization.
Summary of the invention
The purpose of this utility model provides a kind of closed-loop control system of ozone generator, ozone generator ozone output and operation air pressure is accurately regulated, and kept the constant relatively of its process values, guarantees the stable operation of ozone generator.
For achieving the above object, the utility model adopts following technical proposals to be achieved:
A kind of closed-loop control system of ozone generator, wherein, comprise flow sensor, air inlet electric control valve and controller, the analog quantity input end of described flow sensor access controller, the controlled terminal of described air inlet electric control valve are connected on the analog quantity output terminal of described controller.
The closed-loop control system of above-mentioned ozone generator, wherein, the analog quantity input end of described controller is connected to the ozone concentration detector, and the analog quantity output terminal is connected to power supply of ozonizer.
The closed-loop control system of above-mentioned ozone generator, wherein, the analog quantity input end of described controller is connected to pressure transducer, and the analog quantity output terminal is connected to the electric control valve of giving vent to anger.
The closed-loop control system of above-mentioned ozone generator, wherein, described controller is Programmable Logic Controller PLC.
The beneficial effects of the utility model:
Because adopt flow sensor, air intake opening electric control valve and controller to regulate airshed, the actual value of airshed is no more than ± 0.5m with respect to the deviation of setting value in the equipment running process
3/ h has realized the constant relatively of airshed; Owing to adopt the ozone concentration detector, power supply of ozonizer and controller are adjusted ozone concentration, and the actual value of ozone concentration in the equipment running process is no more than ± 1mg/l with respect to the setting value deviation, have realized the constant relatively of ozone concentration; Because adopts pressure sensor, gas outlet electric control valve and controller, operation air pressure is no more than ± 0.01bar with respect to the deviation of setting value in the equipment running process, realizes the constant relatively of operation air pressure.
