The method comprises the following steps of: 1, before coating: placing a suction head of vacuum extraction equipment at an end socket of the hollow fiber hydrogen nitrogen membrane component, and vacuumizing; 2, when coating, placing the hollow fiber hydrogen nitrogen membrane component in a coating container, filling the coating container with coating liquid, and continuously vacuumizing; and 3, after coating, cleanly discharging the coating liquid in the coating container, and then vacuumizing. Through the vacuum coating technology of the hollow fiber hydrogen nitrogen membrane component, the coating process can be controlled according to technological parameters; and the adsorbing effect of the coating is improved. The coating effect of the hollow fiber hydrogen nitrogen membrane component is guaranteed, and the quality of products is guaranteed. Economic benefits are created for enterprises.
Description
Technical field
The present invention relates to the membrane separation technique field, be specifically related to a kind of doughnut nitrogen hydrogen membrane module vacuum coating technique.
Background technology
Doughnut nitrogen hydrogen membrane module coating in the existing market adopts direct immersion type coating mostly.Its shortcoming is only to pass through immersion treatment, and the coating adsorption effect is relatively poor.Do not have reliable data parameters support in the coating procedure, coating quality can't guarantee.Owing to be subjected to process technology limit to make the membrane module after the coating not reach the optimum efficiency of use, affect product quality and manufacturing schedule.In sum, need at present a kind of doughnut nitrogen hydrogen membrane module coating process that can overcome the above problems.
Summary of the invention
Patent of the present invention is intended to solve doughnut nitrogen hydrogen membrane module in problems such as coating process floating coat adsorption effect, coating procedure controllability, end product qualities.
Doughnut nitrogen hydrogen membrane module vacuum coating technique may further comprise the steps:
1. before the coating: the suction nozzle of vaccum-pumping equipment is placed doughnut nitrogen hydrogen membrane component sealing head place, vacuumize processing.
When 2. coating is carried out: doughnut nitrogen hydrogen membrane module is put into coating container, then will fill with coating material liquid in the coating container, continue to vacuumize.
3. after the coating: the discharging of coating container undercoating feed liquid is clean, again vacuumize.
Described vaccum-pumping equipment is rotary-vane vaccum pump.
After 1. described step vacuumizes processing, record vacuum, when described vacuum was-0.098 MPa, the feed liquid proportioning was 3:1.
The described step pumpdown time 2. is 0 ~ 1 hour.
The described step pumpdown time 3. is 0 ~ 1 hour.
Vacuum after 3. described step vacuumizes be-0.096 MPa ~-0.1MPa.
Vacuum after 3. described step vacuumizes be-0.098 MPa ~-0.1MPa.
Doughnut nitrogen hydrogen membrane module of the present invention can according to the process parameter control coating procedure, improve the coating adsorption effect at coating process.Guarantee doughnut nitrogen hydrogen membrane module coating result, thereby guarantee product quality, for enterprise has created economic worth.
