Problems solved by technology

[0003] Each device works independently according to the preset parameters. Even if PLC is used for automatic control, it only monitors the opening and closing time and the operating status of a single unit. When the actual use requirements and working conditions of the entire project change for a short time (such as Water volume), relying on manual adjustment of parameters, cannot track and adjust the operating parameters of the entire project in time, firstly, the water quality after treatment cannot be guaranteed, and secondly, it causes energy waste

Abstract

The invention discloses an automatic control system for ozone generation and water treatment. The system adopts the information technology and the automatic control technology to automatically detect the operation conditions and automatically adjust the operation parameters of each equipment in the whole system through automatic equipment, such as a programmable logic controller PLC, a sensor, a frequency converter, a water treatment technology index (such as ozone concentration or sewage COD (Chemical Oxygen Demand) and the like) online detection instrument and the like, so that the optimal adjustment for various working conditions is achieved, the product quality is guaranteed, the energy is saved, and the manual operation is reduced.

Description

technical field [0001] The invention relates to an automatic control system for ozone generation and water treatment, and belongs to the technical field of ozone preparation and use. Background technique [0002] At present, the gas source required for large-scale production (greater than 1kg / h) of ozone in the world uses liquid oxygen for gasification. Domestically, liquid oxygen gasification or compressed air drying and purification are usually used as gas sources to produce ozone and use it. Because the on-site air treatment is used as a gas source to produce ozone, it is flexible and convenient, and the cost is low. It is generally used in ozone water treatment projects. The process flow is as follows: figure 1 shown. [0003] Each device works independently according to the preset parameters. Even if PLC is used for automatic control, it only monitors the opening and closing time and the operating status of a single unit. When the actual use requirements and working co...
