1, Summarize
The existence of the dissolved oxygen in water is boiler, the heat exchanger and network of pipelines, the main reason for the corrosion corrosion caused the energy and funds serious waste, and at the same time to the safe operation of the equipment is buried hidden trouble. For this, the country "in low-pressure boiler water quality standard of GB (1576 2001) for boiler water supply oxygen device equipped with the proposed clear requirements. In addition, chemical, fertilizer industries in the network equipment and piping in the oxygen corrosion is because the water dissolved oxygen content of excessively high, this kind of corrosion already troubled industries DuoNian technical personnel, the serious influence its energy saving technology improvement of industrial water, people pay more attention to the oxygen up. But at the same time because the traditional oxygen equipment in operation there on their own defects and in many cases can not adapt to the needs, or energy consumption is too large, or to have great influence on the water quality, so oxygen technology development increasing attention.
Analytical oxygen is the use of physical and chemical combination principle will be dissolved oxygen in water removal way.
2, Working principle
Analytical oxygen is based on Henry's law, without the gas and oxygen oxygen mixture, make strong water soluble in water and gas separation of oxygen in the water, and to achieve water quality requirements. Oxygen gas in heating reactor in response to the anaerobic inert gas recycling. According to Henry's law, gas mixture in one of the components in the solubility of liquid [C] and the gas in the boundary of the gas and liquid surface pressure balance points [P] become direct ratio, namely: C = K? P.
3, work process
The water of the processed by oxygen pump to ejector water to certain velocity, through ejector, formed certain negative pressure, and without oxygen gas will be inhaled. Water and no oxygen gas in mixing tube, and then into the mix adequately, the water of the parser dissolved oxygen in the analytical system spread to no oxygen gas. With oxygen gas from the top parser gas water separator, qi water separator after dehydration temperature into heat exchanger to 60 ~ 80 ¡æ, and the heater, and then around into the reactor, the reactor and into the reducing agent after anaerobic reaction again become a gas and move to the next cycle, so as to achieve the purpose of continuous work except oxygen.
