Heat recovery heat supply oxygen making unit for high and cold anoxic environment

Abstract

The invention discloses a heat recovery heat supply oxygen making unit for a high and cold anoxic environment. The oxygen making unit comprises an oxygen making module and a heat supply module. The oxygen making module comprises an air compressor, a multi-stage high pressure filter, a three-phase heat exchanger, a surge tank, two adsorption towers, an oxygen storage tank and a humidification bottle. The multi-stage high pressure filter, the three-phase heat exchanger and the surge tank are sequentially connected behind the air compressor. A stop valve and an electromagnetic valve are sequentially arranged between the surge tank and the adsorption towers connected in parallel. A pressure equalizing valve and two throttling valves are sequentially connected in parallel between the two adsorption towers and the oxygen storage tank. A one-way valve is arranged between each throttle valve and the oxygen storage tank, and a pressure limiting valve and a flow meter are arranged between the oxygen storage tank and the humidification bottle. The heat supply module is connected with the oxygen making module. A oxygen making system and a heat pump system are fully combined, oxygen supply, humidification and heating can be achieved at the same time, adverse reactions caused by low-pressure oxygen deficit, cold drying and the like in high-altitude areas can be reduced, energy dissipation is reduced, heat recovery and utilization are achieved, and the actual requirements of high-altitude areas are met.

Description

technical field [0001] The invention relates to a heating and oxygen generating unit, in particular to a heat recovery heating and oxygen generating unit for an alpine and oxygen-deficient environment. Background technique [0002] Due to the increase in altitude and the decrease in atmospheric pressure in high-altitude areas, a plateau climate characterized by hypoxia, low temperature, strong wind, and dryness is formed. For the indoor environment in high-altitude areas, it is necessary to increase the relative humidity of the indoor environment while ensuring the thermal comfort of the personnel, and to meet the oxygen demand of the personnel. Traditional oxygen supply units can only supply oxygen to high-altitude indoor environments through methods such as pressure swing adsorption and membrane separation, but cannot provide indoor heating, humidification, and solve the problem of indoor drying, so they cannot satisfy the comfort of personnel for indoor environments. nee...
