The design of the core components and the appearance of the process piping was mainly carried out to change the simple and unattractive appearance of the previous small air separation unit.
Design of the structure and shape of the adsorption tower
This design mainly integrates the molecular sieve sinking phenomenon to improve the design of the adsorption tower's inlet and outlet structure and compression structure, so that the shape of the adsorption tower design is integrated, the specific design scheme is as follows
The design of the air splitting device is added at the inlet of the adsorption tower to effectively divert the inlet airflow that enters the adsorption tower instantaneously and quickly, thus reducing the concentrated impact of the inlet airflow and the uniform pressure airflow on the lower plate assembly and increasing the utilisation rate of the lower molecular sieve. Small air separation units inlet gas separation device for conical orifice plate structure, according to the size of the hole change and the conical change of the orifice plate. The airflow direction is changed to achieve the purpose of gas separation.
②In the small air separation unit adsorption tower at the outlet of the gas pipe to increase the design of the gas separation device, direct buffer equal pressure airflow, in the case of the gas cavity remains unchanged, effective diversion equal pressure process in the instantaneous rapid entry of airflow in the adsorption tower, thereby reducing the equal pressure in the two towers equal pressure from the pipeline into the adsorption tower equal pressure gas on the tower on the concentrated impact of the plate.
The Henan Province Air Separation Engineering Technology Research Centre, which is based on DEAR Air Separation, was officially established.
