Abstract: The present disclosure provides a gas liquefaction separator, a gas liquefaction recovery system, and a method for separating and recovering ethylene oxide. The gas liquefaction separator includes a housing, a blocking plate, a gas baffle, and a liquid collector, the latter three being located inside the housing. The liquid collector—an outer edge of which is connected to an inner wall of the housing—is located below the gas baffle, which is located below the blocking plate. The liquid collector includes a first flow guide surface, on a bottom portion of which is disposed a first hole. The gas baffle—an upper surface of which forms a second flow guide surface and an outer edge of which has a protrusion(s)—is connected to the first flow guide surface through the protrusion(s), thereby forming a second hole between the outer edge of the gas baffle and the first flow guide surface.

Abstract: The present disclosure discloses a mobile pretreatment method and apparatus, which may include: a vehicle-mounted system; and a detachable pretreatment chamber fluidly connected to the vehicle-mounted system. The detachable pretreatment chamber may be configured to accommodate an item for sterilization, and may include a temperature and humidity detector, a humidification device, and a water heating device. The vehicle-mounted system may be mountable on a vehicle, and may include an automatic control system, a heating system, a humidification system, and a water inlet system, the latter three being electrically connected to the automatic control system. The heating system may be fluidly connected to the water inlet system, and may be fluidly connected to the water heating device. The humidification system may be fluidly connected to the water inlet system, and may be fluidly connected to the humidification device.
