Multi-stage waste heat recovery heat supply oxygen generation unit

Abstract

The invention discloses a multi-stage waste heat recovery heat supply oxygen generation unit. The multi-stage waste heat recovery heat supply oxygen generation unit comprises an oxygen generation module, a heating module and an auxiliary heat source module, wherein the oxygen generation module comprises an air compressor, a multi-stage high-pressure filter, a three-phase heat exchanger, a pressure stabilizing tank, two adsorption towers, an oxygen storage tank and a humidifying bottle; the multi-stage high-pressure filter, the three-phase heat exchanger and the pressure stabilizing tank are connected to the rear of the air compressor; a stop valve and an electromagnetic valve are arranged between the pressure stabilizing tank and the adsorption towers connected in parallel; a pressure equalizing valve and two throttling valves are arranged between the two adsorption towers and the oxygen storage tank; a one-way valve is arranged between the throttling valves and the oxygen storage tank, and a pressure limiting valve and a flow meter are arranged between the oxygen storage tank and the humidifying bottle; and the heating module is connected with the oxygen generation module. According to the multi-stage waste heat recovery heat supply oxygen generation unit, an oxygen generation system and a heat pump system are fully combined, oxygen supply, humidification and heating can be carried out at the same time, adverse reactions caused by low-pressure oxygen deficiency, cold drying and the like to people in high-altitude areas can be reduced, energy dissipation is reduced, heat recovery and utilization are realized, and the actual requirements of the high-altitude areas are met.

Description

technical field [0001] The invention relates to a heating and oxygen generating unit, in particular to a multi-stage waste heat recovery heating and oxygen generating unit. 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. need. [0003] In high-altitude...
