Qing Rui industries involved in environmental technology, air separation, air purification, electrical equipment, automation equipment, and other fields. Has its own R & D institutions, R & D personnel ratio of 70% share of all employees, the business products with independent intellectual property rights. From the company since its establishment: won two invention patents, utility model patents, 7, 11 appearance patents, including "prioritization based on molecular size filtration technology and PSA oxygen technology" and "negative ion generating means oxygen machine "was patented, fill the gaps, to solve the technical bottlenecks oxygen at home and abroad, the products include a variety of environments using the oxygen machine, purifiers and other cleaning equipment. Swiss engine works a commercial oxygen, oxygen principle: the air is a major complication of gas from oxygen, nitrogen, argon and other gases consisting of a mixture consisting essentially of table, in addition to a fixed group of exceptionally listed in the table, Air also contains a variable number of dust, water, acetylene, and sulfur dioxide, hydrogen sulfide, nitric oxide, nitrous oxide and other trace impurities. PSA adsorption technology is the use of a molecular sieve oxygen adsorption and desorption of physical technology in the oxygen loaded molecular sieves can be in the adsorption of nitrogen in air pressure, the remaining oxygen is not absorbed is collected and, after purification treatment and then becomes High purity oxygen. Nitrogen bleed air back into the environment of the molecular sieve adsorbent at the reduced pressure, the pressing time and the next time the preparation can adsorb nitrogen and oxygen, the process is a dynamic cyclic process periodically, the molecular sieve is not consumed. Specific principles shown below: oil-free air compressor air through the compressor, compressed air flow solenoid valve inlet P, when the solenoid valve is controlled by the control panel. a, the solenoid valve is energized, compressed air from P → A, and then flows to the solenoid valve A port zeolite (A beds), pressurized air is molecular sieve adsorption of nitrogen, oxygen enters the oxygen storage tank is collected and then dried required pressure regulating valve modulation (0.03 ~ 0.07mpa) regulated output, control output flow through the meter for oxygen use. Another pass desorption pore molecular sieve (B bed), carried out on the B-bed flushing desorption, gas desorbed by a solenoid valve B exhaust muffler exhaust port to the atmosphere. b, when the solenoid valve is energized, compressed air from P → B, then from B port solenoid valve flow sieve (B bed), with pressure air is molecular sieve adsorption of nitrogen, oxygen enters the oxygen storage tank, and then by the regulator valve modulation required pressure (0.03 ~ 0.07mpa) regulated output, controlling the flow through the meter for oxygen use. Another pass desorption pore molecular sieve (A beds), were rinsed desorption of bed A, the desorbed gas mixture through the exhaust port solenoid valve B muffler discharge to the atmosphere. This way you can take the oxygen system to protect the oxygen concentration in the preparation of high traffic, environmental protection and pollution-free. Swiss Business Advantage engine is split oxygen zeolite molecular sieve as adsorbent, oxygen and nitrogen in the air with the physical separation of pressure swing adsorption (PSA), and filter out the harmful substances in the air, thus obtaining high purity oxygen. Product Features: 1: Diffusion of oxygen, eliminating the oxygen tube and mask wearing discomfort and inconvenience. 2: oxygen automatic humidification, effective protection from harm respiratory oxygen staff make breathing feel more fresh and comfortable.! 3: aerobics, purification and disinfection, renewal wind, the three main functions, all to meet your health needs. 4: The device can run (-40 ℃ to 45 ℃) in a high temperature environment alpine 5: French CECA top international companies SXSDM super efficient molecular sieves, to protect the oxygen concentration of 5 years will not decay. 6: A unique design of gas-water separator, separation of air and water, to ensure that water can not enter the zeolite molecular sieve effective long-term protection. 7: The United States TOMAS compressor to ensure the efficient and long-lasting operation of the equipment. 8: electromagnetic gas distribution valve, microcomputer control system, produce oxygen more evenly. Second, air purification and disinfection of air purifier, also known as "air cleaners", air cleaners, refers to the ability adsorption, decomposition or transformation of various air pollutants (usually including decoration pollution dust, pollen, odors, like formaldehyde, bacteria , allergens, etc.), improve air cleanliness products, now to clear the indoor air pollution of residential and commercial air purifiers based. 1, HEPA adsorption: HEPA air filter for the efficient means to achieve the standard HEPA filter for 0.1 micron and 0.3 micron with 99.7% efficiency, the characteristics of HEPA air by the network, but the small particles can not pass. It has a diameter of 0.3 microns (1/200 the diameter of the hair) or more particle removal efficiency can reach more than 99.97%, smoke, dust, bacteria and other contaminants, and the most effective filtration media. 2, activated carbon adsorption: equipment rooms, air conditioning rooms, basements and subsea facilities in the air, due to outside contamination or affected by the activities of people in a closed environment, which often contain odor, smoke smell, the smell of cooking oil, organic and inorganic sulfur compounds, corrosive composition, the organic sulfur compounds, hydrocarbons, chlorine, oil, mercury and other environmentally harmful components, after adsorption with activated carbon may be in the discharge. Atomic gas release device, krypton, xenon, and other substances containing radioactive iodine must be used after they are adsorbed by the activated carbon again clean emissions. Coal, heavy oil combustion flue gas containing sulfur dioxide and nitrogen oxides, affect human health. Activated carbon can be used to purify out impurities ingredients. 3, negative ion purification: In the medical profession, (High Voltage) anion was identified as an effective means to kill bacteria and purify the air has. The mechanism mainly after negative bacteria combine to make the change or transfer of bacteria to produce energy structure, leading to bacterial death, eventually settling on the ground. Medical research shows that the negatively charged particles in the air so that the oxygen content of the blood increases, favor oxygen transmission, absorption and utilization, with the promotion of human metabolism, improve human immunity, increase body functions, the regulatory function of functional balance. Aeroanion formula is O2- (H2O) n, or OH- (H2O) n, or CO4- (H2O) n. Mentioned here are nitrogen oxides produced by cigarettes and other reactive oxygen species (oxygen free radicals), reduce excessive reactive oxygen species on the human body; positively charged particulates in the air without charge after the settlement, purify the air. 4, ozone (O3) Decomposition: Ozone chemical formula O3, ozone has strong oxidation resistance, by the oxidation reaction can effectively remove toxic gases such as CO, SO2, mustard gas and the like. O3 + CO = CO2 + O2 III: renewal wind Qing Shui commercial indoor unit features a split oxygen intake port connected to the host via pipeline compressor, compressor produced by suction to extract indoor gas. Equipped with two ways: 1: Single Compressor: indoor gas through the suction port to reach the host, after the adoption of a multi-layer filter into the compressor --- zeolite molecular sieve again after gas separation by implantation chamber, the biggest advantage is that it can effectively saving air conditioning resource. 2: Dual Compressor: indoor gas through the suction port to reach the host, by a natural air compressor is responsible for collecting and providing pressure. Another gas compressor responsible for taking indoor and outdoor direct emissions, inhale a large amount applicable to a larger space. Four: the need for supplemental oxygen crowd: 1, the elderly need oxygen to compensate for the decline may be directly caused by lack of oxygen physiological function, maintain the normal function of the body organs, prevent hypoxia caused by a variety of geriatric and maintain physical and mental health , slow the aging process, the effective removal of physically weak fatigue, lightheadedness, dizziness and other symptoms; especially when emotional oxygen immediately, you can quickly relieve angina, cerebral thrombosis, stroke and other conditions. 2, pregnant women need oxygen can increase the oxygen content of the parent, the oxygen content increased so that the fetus can be more adequate access to oxygen, to the benefit of protecting the health of the mother and the fetus better development. 3, students need to feel awake after oxygen oxygen, responsive memory enhancement, energetic. Ease the tension of learning exams, correcting brain fatigue, nerves Limianye, avoid causing brain damage. 4, white-collar nature of sub-health state is needed oxygen hypoxia, produced after a long period of mental fatigue and dizziness, headache and discomfort are hypoxic response, and directly led to decreased work efficiency; suitable for white-collar oxygenating class is very important, to improve efficiency and mental state, stress levels. 5. mental need supplemental oxygen sufficient oxygen can quickly restore brain activity, improve brain function, so the mental need oxygen. 6, severe air pollution beauty care modern cities, the real oxygen absorbed into the body greatly reduced, living in this environment of white-collar women's appearance and health will be seriously threatened, causing hypoxia will be one of the main cause of many diseases . Sufficient oxygen can promote female skin blood circulation, metabolism of skin tissue more active, while accelerating the discharge of toxins, add water, while supplemental oxygen, making skin more youthful and elastic. 7, the patient needs oxygen to oxygen can reduce the incidence of regular frequency, improving the function of internal organs, enhance immunity. Long-term oxygen therapy, for recovery of the disease has a very important role.
