Abstract

The invention discloses an integrated program-controlled valve group formed by 3D printing. By utilizing the advantages of fast and accurate molding of 3D printing technology, an integrated program-controlled valve group with its own internal integrated flow channel is obtained. Pipelines and valve components are integrated in the integrated program-controlled valve group in the form of unit blocks, so that the on-site valve area of ​​the adsorption treatment system has a compact structure and reduced volume, which is convenient for modularization, skid-mounting, equipment and vehicle-mounting; at the same time, For this integrated program-controlled valve group, a new 3D printing molding process combining "printing molding + infiltration process + sintering process" is provided, which combines the characteristics of 3D printing rapid prototyping, and makes the inner wall surface of the complex flow channel after the part is formed. It is smooth and has excellent anti-wear and anti-cavitation capabilities, which completely solves the difficulties in processing and forming when the flow channel integration is too high during the skid-mounted design process of the valve area of ​​the adsorption treatment system and the flow channel wall after forming. The problem of poor surface properties.

Description

technical field [0001] The invention relates to the field of integrated control valve groups, in particular to an integrated program-controlled valve group formed by 3D printing. Background technique [0002] With the continuous development and progress of industries such as semiconductors and hydrogen fuel cells, the market demand for high-purity gases including hydrogen and ammonia is increasing, and the quality requirements are also getting higher and higher. In addition, due to the high cost and low utilization rate of the high-purity gas used, the separation, purification, recovery and reuse of the corresponding gas has also become one of the focuses of enterprises. [0003] As the most effective gas deep separation and purification technology at present, temperature swing adsorption and pressure swing adsorption, both of which use molecular sieves carrying gas adsorbates to have different adsorption properties for different gas molecules under different temperature or ...
