Description

Technical Field

[0001] The utility model relates to the technical field of gas purification, in particular to an integrated valve block for an adsorption drying device. Background Art

[0002] The assembly diagram of the upper and lower valve groups in the traditional production process of the adsorption drying device is as follows: Figure 1 and Figure 2 As shown, the lower valve group is mainly composed of a left air intake valve 101, a right air intake valve 102, a left vent valve 103, a right vent valve 104, a vent silencer 107 and pipelines; the upper valve group is mainly composed of a left gas production valve 105, a right gas production valve 106, a purge pipe 108 and pipelines. The components numbered 101 to 106 are opened and closed according to a certain timing logic, thereby realizing the continuous operation of the adsorption drying device and outputting dry air.

[0003] The logic of controlling the fluid flow direction of components No. 101 to 106 is as follows:

[0004] When the left adsorber is working, No. 101, 104, 105 are opened, No. 102, 103, 106 are closed, and the wet air enters the left adsorber through the left pipeline of the lower valve group, and the dry air is output through the left pipeline of the upper valve group after the adsorption of the filler in the adsorber; at the same time, the dry air is purged into the right adsorber through No. 108, and the moisture adsorbed by the filler in the right adsorber flows to No. 107 through No. 104 for venting. When the left adsorber is finished adsorbing, the right adsorber is emptied. At this time, No. 101, 104, 105 are closed, and No. 102, 103, 106 are opened. Open, wet air enters the right adsorber through the right pipeline of the lower valve group, and is output through the right pipeline of the upper valve group through the adsorption effect of the filler in the adsorber; at the same time, dry air is purged into the left adsorber through number 108, and the moisture adsorbed by the filler in the left adsorber flows to number 107 through number 103 for discharge. When the adsorption of the right adsorber is completed, the discharge of the left adsorber is completed. At this time, numbers 102, 103, and 106 are closed, and numbers 101, 104, and 105 are opened, and the left adsorber performs adsorption work. This cycle realizes the continuous operation of the adsorption drying device and outputs dry air.

[0005] However, the valve group assembled by the traditional production process has large external dimensions, many threaded connection interfaces (the above-mentioned valves and pipelines are all threaded connections), a large welding workload, and a complicated assembly process, which reduces production efficiency. In addition, due to the large number of threaded connection interfaces, it also increases the risk of pipeline leakage and the difficulty of maintenance. Utility Model Content
