PROBLEM TO BE SOLVED: To provide a VOC (volatile organic compound) removal solution regeneration and recovery apparatus in which no heater is used and no gas-permeable membrane is required and therefore volatile substances and the like are not adversely affected when passing through the gas-permeable membrane, and also to provide a VOC removal solution regeneration and recovery method therefor.SOLUTION: The VOC removal solution regeneration and recovery apparatus includes: a liquid feeding pump and a nozzle that spray the VOC removal solution; a vacuum vessel that has the nozzle disposed inside thereof; a vacuum pump that reduces pressure of an interior of the vacuum vessel and performs vacuum-evaporation of the VOC included in the VOC removal solution; a gas introducing mechanism that introduces evaporation enhancing gas into the vacuum vessel; and a liquid discharge mechanism that discharges the processed VOC removal solution from the vacuum vessel. The apparatus further comprises a compressor that compresses air from the outside and generates compressed air having thermal energy and pressure energy. A heat exchanger is provided at a passage from the liquid feeding pump to the nozzle, heat exchange between the VOC removal solution and the compressed air is performed by the heat exchanger, and the thermal energy is supplied to the VOC removal solution. The liquid feeding pump is an air-driven pump that is driven by air pressure as a power source, and the pressure energy of the compressed air is used as the power source of the pump. |
