Embodiment Construction

[0008] The present invention is specifically described below in conjunction with accompanying drawing, as figure 1 It is a structural schematic diagram of the purification process of the intake and exhaust outlets at the bottom of the methanol cracking hydrogen production adsorption tower of the present invention. As shown in the figure, the process includes the following contents:

[0009] Add a DN200*320 filter to the flange where the inlet and exhaust ports of the adsorption tower bottom of the methanol cracking hydrogen production unit are located, and punch holes in the DN200*320 filter, and finally wrap stainless steel wire mesh outside the DN200*320 filter 9. In order to prevent the adsorbent from leaking and causing damage to the sealing sheet.

[0010] The feature of this technical solution is that the leakage of the adsorbent in the adsorption tower causes damage to the sealing plate of the program-controlled valve, which causes safety and product purity problems and...

Abstract

The invention discloses a purifying process for air inlet and outlet on the bottom of an adsorption column of methanol cracking to produce hydrogen. The process includes adding a DN200*320 filter on flanges of the air inlet and outlet on the bottom of the adsorption column of a methanol cracking to produce hydrogen device, punching the DN200*320 filter to form holes, and coating the DN200*320 filter (9) with a stainless steel wire mesh to prevent leakage of an adsorbent and damage of a sealing sheet. The purifying process can prolong the service life of the equipment and increase economic benefit.

Description

technical field [0001] The invention relates to the field of methanol cracking hydrogen production technology, in particular to a purification process for inlet and exhaust outlets at the bottom of an adsorption tower for methanol cracking hydrogen production. Background technique [0002] The adsorption tower has the phenomenon of adsorbent leakage, and the adsorbent enters the pipeline of the program-controlled valve through the intake and exhaust ports, causing damage to the sealing sheet of the program-controlled valve. It is not only a safety hazard, but also affects the purity of hydrogen, and leads to high maintenance rates and economic losses. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems and design a purification process for the intake and exhaust outlets at the bottom of the adsorption tower for hydrogen production by methanol cracking. [0004] Achieving the above-mentioned purpose The technical ...
