Description

Continuous dehumidification device and sample analyzer

Technical Field

The invention belongs to the technical field of air dehumidification, and particularly relates to a continuous dehumidification device and a sample analyzer.

Background

Currently, there are four main dehumidification methods in the market:

firstly, cooling and dehumidifying, namely cooling the air under normal pressure to be below the dew point temperature, and discharging the water vapor after the water vapor is condensed into water; therefore, cooling dehumidification requires an independent liquid path to discharge condensed water out of the device, so that the device is more complex and bulkier in design; and meanwhile, the risk of dripping and damaging electronic components can be increased by the generated condensed water.

Secondly, compression dehumidification, namely compressing air and then naturally cooling the air to condense water vapor in the air into water for discharge; however, the compression dehumidification requires additional air compression equipment, which increases the manufacturing cost of the apparatus, increases the operation cost, and generates a loud noise.

Thirdly, solid adsorption type dehumidification, namely dehumidifying air by using a large-area dehumidifying agent or dehumidifying strip containing adsorbing materials; in the solid adsorption type dehumidification technology, when the dehumidification medium is saturated by adsorbing enough moisture, the dehumidification function is lost, so that the dehumidification medium needs to be replaced at regular time.

And fourthly, liquid absorption type dehumidification, namely, the moisture absorbent aqueous solution is sprayed to dehumidify the air. At present, the equipment required by liquid absorption type dehumidification is huge, and absorption liquid is required, so that the use scene is limited.

The molecular sieve is a kind of synthetic hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules. It has many pore canals with uniform pore diameter and regularly arranged holes, and molecular sieves with different pore diameters separate molecules with different sizes and shapes. It has the features of high adsorption capacity, high selectivity and high temperature resistance, and is one excellent adsorbent.
