Abstract

The invention provides a liquid nitrogen cooling dehumidification device. The liquid nitrogen cooling dehumidification device comprises a heat exchanger, a liquid-collecting chamber and a liquid nitrogen liquid inlet pipe, wherein the heat exchanger includes a plurality of liquid nitrogen heat exchanging pipes, and a gap is formed between every two adjacent liquid nitrogen heat exchanging pipes; the liquid-collecting chamber communicates with the multiple liquid nitrogen heat exchanging pipes and is arranged at the bottoms of the multiple liquid nitrogen heat exchanging pipes; and the liquid nitrogen liquid inlet pipe communicates with the liquid-collecting chamber. The liquid nitrogen cooling dehumidification device is compact in layout and simple in structure and has no complex parts; the heat exchanging temperature of the liquid nitrogen cooling dehumidification device is low, air can be made to reach a very low dew point, and the dehumidification effect is good; nitrogen produced after liquid nitrogen is evaporated further dilutes water vapor in the dry air, and the mixing ratio of the water vapor is further reduced; and the temperature of the dry air sent back to a room can becontrolled, and requirements of different conditions are met accordingly.

Description

technical field [0001] The invention relates to a liquid nitrogen cooling and dehumidification device. Background technique [0002] Water vapor exists in the air, and the warmer the air, the higher its capacity to hold water vapor. For some special equipment that needs to work in a dry environment, it is necessary to control the humidity of its working environment. At present, common dehumidification technologies mainly include: cooling dehumidification, adsorption dehumidification, absorption dehumidification, compression dehumidification, membrane dehumidification, etc. Cooling and dehumidification is to contact the gas with the wall of the liquid or solid medium whose temperature is lower than its dew point, so that the water vapor will condense and stay in the liquid or the solid contact surface, thereby removing the water vapor. Adsorption dehumidification refers to the use of solid adsorbents to absorb water vapor in the gas to achieve the dehumidification effect. R...
