Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] The invention relates to a process method for preparing extremely dry gas, which can be used to prepare dry gas with a dew point of -70--120°C (water content less than 1ppmv).

[0019] The principle of the present invention is to use the principle that molecular sieves (the types of molecular sieves are: 3A, 4A, 5A, 10x, 13x and other general types) can absorb water to absorb and eliminate the saturated or unsaturated water contained in the gas. Utilizing the characteristics of molecular sieves that can release moisture at high temperatures, heat and dehydrate it (the term is called: regener...

Abstract

The invention discloses a novel gas drying device comprising drying towers, gas-water separators, drain valves, coolers and a dividing valve. The coolers are connected with the gas-water separators; the gas-water separators are connected with the drying towers; the drying towers are connected with the dividing valve; and the novel gas drying device adopts fully-conductive four-way valves. The novel gas drying device has the advantages that the airflow control valves are greatly saved, the control complex degree and the equipment cost are reduced, and pressure keeping down or airflow confusion can not be generated to cause hazard or harm even when some valves are out of control.

Description

technical field [0001] The invention belongs to the field of chemical equipment, in particular to a novel dry gas device. Background technique [0002] At present, the methods of using molecular sieves to dry gas include: pressure swing adsorption method, temperature swing adsorption method, etc. like figure 1 As shown, the pressure swing adsorption method needs to discharge a large amount of regeneration gas when drying gas, which is not suitable for precious rare gases and flammable, explosive, toxic and harmful gases. The usual process of drying gas by temperature swing adsorption method has two drying towers. The product gas is used as the regeneration gas, and the regeneration gas is emptied. Although the amount of the evacuated regeneration gas is less than that of the pressure swing adsorption method, it is still not suitable for precious rare gases and flammable, explosive, toxic and harmful gases. [0003] The invention patent of the No. 718 Research Institute of ...
