Description

Technical Field

[0001] The utility model relates to coke-related fields, in particular to a coke gas hydrogen stripping device. Background Art

[0002] Coke is a kind of solid fuel, obtained by dry distillation of coal at a high temperature of about 1000℃. Its main components are fixed carbon, followed by ash, and it contains very little volatile matter and sulfur. It is silver-gray, metallic, hard and porous, and its calorific value is mostly 26380~31400kJ / kg (6300~7500kcal / kg). According to different uses, there are three categories: metallurgical coke, foundry coke and chemical coke.

[0003] The Chinese patent with patent announcement number CN215161007U discloses "A coke gas hydrogen extraction device".

It does not need to be repaired and disassembled as a whole, thus reducing the use cost. The one-way valve is arranged to prevent the backflow of coke gas. When the compressor pressurizes the inside of the equipment through the compressor interface, the coke gas will pass through the adsorption device arranged inside the first adsorption box and the second adsorption box in turn, which can adsorb and remove impurities in the coke oven gas. The arrangement of the filtering separation membrane can utilize the characteristics that the relative permeation rates of different gases in the membrane are different to achieve the purpose of separating the mixed gas, and can filter out high-purity hydrogen.
