technical field

This utility model discloses a system for analyzing the concentration of aerobic tail gas after the treatment of Huangoxygen water. It can accurately calculate the dosage and utilization rate of ozone in water based on the concentration of oxygen in the tail gas, and can also improve the process efficiency of ozone water treatment based on the parameters of tail gas concentration. Back ink technology

Oxygen has strong oxidizing ability, which can destroy the molecular structure of organic pollutants and change their properties. Under certain conditions, it can improve the ability of conventional processes to remove constant organic matter, and has strong sterilization and disinfection effects. It also has the functions of deodorization, fading, iron and manganese removal, and can effectively oxidize and decompose organic matter.

The Guangdong Oxygen Water Treatment Method does not require the addition of other chemical agents to the water. The color of the water is mainly caused by dissolved organic matter, floating colloids, iron and manganese, and particulate matter. The strong oxidizing ability of oxygen can make the water clearer. Oxygen has strong oxidizing properties and can oxidize various compounds. Moreover, it has the advantages of low consumption, fast reaction speed, and no leakage. Therefore, it has been successfully applied in drinking water, industrial wastewater, and circulating cooling water treatment processes. Especially in the past two decades, it has been found that ammonia disinfection can produce carcinogenic trioxane to the human body(THMS)The efficiency of ozone in killing chrysanthemums and viruses is much better than that of hydrogen disinfection. At the same time, it can effectively remove inorganic substances such as color, odor, iron, manganese, etc. from water, and can also reduceUVAbsorption valueTOCTheCODAnd with the addition of chlorine and nitrogen, the oxygen oxidation technology has been increasingly widely used in water treatment, leading to the development of various more effective composite treatment processes.

However, the oxygen generation capacity of a reoxygenation generator that can be used for adding oxygen is largely affected by factors such as the humidity of the gas source, the temperature of the cooling water, and the aging of the discharge surface. Therefore, it is necessary to regularly monitor the oxygen concentration. For large-scale oxygen equipment,**There are high concentration oxygen gas detectors installed in the process, as well as dissolved oxygen detectors for detecting mixed water, and detectors for detecting the concentration of ozone in the exhaust emissions. In order to control the entire system to be in***.

Specific implementation method

The following will provide a clear and complete description of the technical solution in the embodiments of the present utility model, based on the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, not all of them. Based on the embodiments described in this utility model, all other embodiments obtained by technical personnel in this field without creative labor are within the scope of protection of this utility model.

The sampling gas is taken out from the sampling outlet needle valve and connected***The stage gas-liquid separator first separates a portion of the ozone gas liquid with moisture, and then connects a dual channel electronic cooler to remove and dry the moisture in the oxygen gas through the electronic cooler. The condensed water is discharged into the container inside the electronic automatic drainage device, which will automatically drain under negative pressure conditions based on the liquid level. The sampled gas is cooled and removed by the dual channel electronic cooler before passing through the first stage gas-liquid separator. To prevent impurities from entering the UV absorption Raman oxygen analyzer, clean and dry sampling gas enters the UV oxygen concentration analyzer for analysis and detection of oxygen concentration. As this oxygen analysis system is in a negative pressure detection state“**The pressure is lower than the standard atmospheric pressure, so the ultraviolet summer oxygen concentration analyzer must have temperature and pressure compensation. After being detected by the outdoor ozone concentration analyzer, the ozone gas is decomposed and reduced by the ozone analyzer tail gas disruptor. After passing through the negative pressure suction pump, the sampled gas is transported to the same path smoke for sampling, and the detected gas returns to the ozone tail gasmain pipeline.
