The invention discloses an afterheat and excess moisture utilization energy-saving fresh air oxygen supply system. The system comprises an air compressor, an air storage tank, a sucking machine, a variable pressure absorber, an oxygen storage tank, a fan, an oxygen preparation section, an activated carbon filter, an air filter and a total heat exchanger; the total heat exchanger communicates withan air return port and a fresh air port; the total heat exchanger is connected with the air filter; the air filter is connected with the oxygen preparation section through the activated carbon filter;the oxygen preparation section is connected with the air compressor through an air compressor inlet, is connected with the sucking machine through a first branch pipe, and is connected with the oxygen storage tank through a second branch pipe; oxygen generated by the oxygen preparation section is fed indoors through the fan; the air compressor is connected with the air storage tank; the air storage tank is connected with the sucking machine; the sucking machine is connected with the variable pressure absorber; and the variable pressure absorber is connected with the oxygen storage tank and the total heat exchanger. The system can achieve the functions of synchronous oxygen supply, afterheat utilization and humidification, and achieves the purposes of energy conservation and excess moisture utilization.
Description
technical field [0001] The invention relates to an oxygen supply system, in particular to an energy-saving fresh air oxygen supply system utilizing waste heat and humidity. Background technique [0002] China is the country with the largest plateau area in the world. Among them, the Qinghai-Tibet Plateau, known as the "roof of the world", accounts for about 1 / 4 of the country's land area, with an average altitude of more than 4500m. The plateau has the characteristics of low pressure, low oxygen, cold, large temperature difference between day and night, dryness, strong radiation and strong ultraviolet rays. As the altitude increases, the partial pressure of atmospheric oxygen decreases, and the partial pressure of arterial oxygen in the human body also decreases. The basic needs of the body can only be met when the partial pressure of arterial oxygen is higher than 7.98kPa. People who rush into the plateau are prone to acute altitude sickness due to a series of acute hypoxi...
