Embodiment

[0041] Example: attached figure 1It is a structural representation of the present invention. Including the adsorption and regeneration process carried out separately in different adsorption towers, the regeneration process includes heating and cold blowing process, characterized in that the method is carried out in three adsorption towers with the same adsorption capacity and the same specific heat of the adsorbent , the three adsorption towers are Tower A, Tower B, and Tower C, and the following steps a, b, and c are performed alternately:

[0042] a. When tower A is regenerated, tower B is the main adsorption, and tower C is the secondary adsorption

[0043] Tower A is heated, and tower B is adsorbing at this time, and the flow direction of its compressed air is as follows:

[0044] High temperature compressed air inlet-tower A-cooling-tower B-product gas outlet,

[0045] Tower A is cold blowing, at this time tower B and tower C are adsorbing, and the flow sequence of the...

Abstract

The invention relates to an absorption drying method utilizing compression heat to regenerate the air. The method comprises absorption and regeneration processes which are performed in different absorption towers respectively, and the regeneration process comprises heating and cold blowing processes. The method is characterized in that the method is performed in three absorption towers with adsorbents having the same absorption capacity and same specific heat, the three absorption towers are the tower A, the tower B and the tower C respectively, and the regeneration and absorption processes are alternately performed by the following a, b and c steps. The method has the characteristics of low energy consumption, no loss of gas consumption, simple operation, convenient use and the like.

Description

technical field [0001] The invention relates to a drying method, in particular to an adsorption drying method which utilizes compression heat to regenerate air. Background technique [0002] In the domestic market, the most commonly used compression heat with gas consumption is generally composed of two adsorption towers and a water cooler, and the two adsorption towers work alternately. 100% high-temperature compressed air enters the regeneration tower, and the heat of the high-temperature compressed air is used to heat the adsorbent in the adsorption tower. Because the gas is in a high-temperature state, the relative humidity saturation is low, and the water absorption capacity is strong, and the adsorbent can be taken away while heating Most of the water in. Then all the compressed air enters the water cooler on the dryer to lower its temperature to 40°C, and then passes through the gas-water separation and automatic drainage device to discharge the liquid water to obtai...
