Description

Technical Field

[0001] The present invention relates to the technical field of comprehensive resource utilization, and in particular to an analysis system and method for controlling residual ozone concentration. Background Art

[0002] Urban industrialization has caused the deterioration of the ecological environment. The total amount of atmospheric pollutant emissions has been decreasing year by year. The air quality of some cities with serious pollution has improved, but the problem of O3 pollution has become increasingly prominent. In the stratosphere of the atmosphere, there is a layer with a high concentration of ozone, which is called the ozone layer. The ozone concentration in the ozone layer is about 1 to 10 ppm. It can absorb ultraviolet radiation, warm the atmosphere, and protect the organisms on the earth. However, ozone in the near-ground troposphere can cause harm to the environment and human health. It can turn plant leaves yellow and reduce the efficiency of photosynthesis, resulting in reduced crop yields and decreased species diversity. In addition, people who are exposed to ozone pollution for a long time may suffer from respiratory diseases such as asthma, emphysema, and bronchitis, and may also cause health problems such as immune system disorders and damage to the nervous system. Therefore, it is very necessary to reduce ozone pollution in the near-ground troposphere.

[0144] When the second residual ozone concentration does not meet the emission standards, directly discharging the treated gas will cause environmental pollution, but the efficiency of treating the gas that does not meet the emission standards separately each time is low. Therefore, the present invention determines the spatial parameters of the terminal collection space of the collection channel based on the decomposition system design information, determines the third residual ozone concentration of the terminal collection space when the spatial pressure value of the terminal collection space reaches the spatial pressure threshold, and constructs the indication instruction determination factor based on the spatial parameters and the third residual ozone concentration. The control library of the re-reaction device is introduced, the factor is determined according to the indication instruction, and the indication instruction is issued, thereby improving the adequacy of the re-reaction.

[0148] Step 3: obtaining a second residual ozone concentration after the residual ozone gas is decomposed by catalytic oxidation;

[0149] Step 4: Determine whether the second residual ozone concentration meets the emission standard. If so, discharge the decomposed gas.

[0150] In one embodiment, step 1: determining a first residual ozone concentration of residual ozone gas after the cooking fume exhaust gas is treated, comprises:

[0151] Use high voltage static electricity to remove particulate matter and oil smoke from the exhaust gas to obtain treated gas;
