Problems solved by technology

The disadvantage of this method is that the source of liquid nitrogen is difficult to guarantee, and the pump volume of the air pump is small, resulting in a small amount of water vapor collected. At the same time, the use of the air pump will also increase the temperature of the air, which is not conducive to the condensation of water vapor.
The above three methods obviously cannot meet such needs.

Abstract

An outdoor high-efficiency air tritiated water vapor condensation collection device includes an evaporator assembly, a capillary tube, a thermal expansion valve, a one-way valve, a condenser, an electromagnetic reversing valve, and a compressor. The evaporator assembly includes a fan, a spiral finned tube, and an external Cylinder body, air inlet, central cylinder, water collection bucket, collection bottle, spiral finned tube coiled on the outer surface of the central cylinder, spiral finned tube and central cylinder are sleeved inside the outer cylinder together, the fan is located on the top of the outer cylinder, and the air inlet Arranged on the outer surface of the outer cylinder, the bottom of the outer cylinder is equipped with a water collecting bucket, and the outlet of the water collecting bucket receives the collecting bottle. When the dew point temperature corresponding to the ambient temperature is higher or lower than 0°C, the vapor formed by the compressor working on the gaseous refrigerant passes through different circulation paths, so that the tritiated water vapor contained in the air condenses into water on the spiral finned tube And flow into the collection bottle along the water collecting bucket. The device of the invention has the advantages of simple structure, wide working temperature range, convenient maintenance and strong versatility, and is suitable for various field working environments.

Description

technical field [0001] The invention relates to a water vapor collection device, in particular to a device for condensing and collecting air tritiated water vapor suitable for field operations. Background technique [0002] The tritium element produced after the nuclear reaction is generally attached to the water molecules in the air, and the detection of the tritium element content in the air can help the development of environmental monitoring and national defense scientific research sampling. [0003] At present, there are generally three ways to sample tritiated water vapor in the air in China: the first is to place the serpentine tube in a container filled with liquid nitrogen, and use an air pump to make ambient air flow through the serpentine tube, and the water will The steam condenses into water on the pipe wall before being collected. The disadvantage of this method is that it is difficult to guarantee the source of liquid nitrogen, and the pump volume of the air ...
