Embodiment Construction

[0051] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0052] The present invention mainly involves two main points:

[0053] 1. Establishment of program standardization components

[0054] The standardized components are mainly to improve the reusability of the program, and at the same time improve the standardized components in the continuous application process. So as to improve the operation reliability of the whole ozone system.

[0055] There are two types of standardized components in the automatic control system: actual controlled objects and functional objects. The actual controlled objects are the equipment and valves in the system; the functional objects are data calculation, process control, adjustment parameter preset, etc.

[0056] Standardized components encapsulate data and logic based on certain objects and functional categories, and do not need unified interfaces and interface data type...

Abstract

The invention discloses a process structured ozone system based on object control. The system includes four process sections, i.e., gas source gas station, generating chamber, pre-ozonation and main ozonation. A program unit is arranged in each process section, and each program unit includes an address mapping unit which is called immediately when the ozone system is powered on for operation, an alarm unit which is called immediately when the ozone system is powered on for operation, a function object unit which is called immediately when the ozone system is powered on for operation, a flow control unit which is called when the ozone system is powered on for operation, and a function regulation unit which is a loop of each process section which performs PID closed-loop control. The program of each process section of the system adopts standardized objects and functions, thereby lowering the requirements of the degree of familiarity with complicated control processes of the ozone system during programming of electronic control personnel and design personnel and on-site automatic control debugging of debugging personnel.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a process structured ozone system based on object control. Background technique [0002] The ozone oxidation system (referred to as the ozone system) is an important part of the water quality advanced treatment process. Generally, the process configuration of a large-scale ozone system is as follows: figure 1 As shown, it can be divided into four process sections: gas source gas station process section, generation room process section, pre-ozone process section and main ozone process section, wherein the gas source gas station process section is an on-site oxygen production process section, of course , the gas source gas station can also directly provide liquid oxygen; the process section of the generation room includes an auxiliary gas source (compressed air system), a nitrogen addition unit, and an ozone production unit. Oxygen is mixed in a certain proportion (proport...
