Embodiment Construction
[0028] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] Such as figure 1 , figure 2 , image 3 As shown, a coke oven gas purification system includes a feeder, a first fine-removal tower, a second fine-removal tower, a third fine-removal tower, a fine removal tower and a collector connected in sequence. The feeder is used for the feeding of coke oven gas, and pressurizes the coke oven gas after rough desulfurization; Activated carbon microspheres are arranged in the stripping tower; the second fine stripping tower is used for secondary fine stripping of the coke oven gas passing through the first fine stripping tower, and activated carbon fibers are arranged in the second fine stripping tower; the third fine stripping tower The tower is used for three-stage fine stripping of coke oven gas passing through the second...

The invention discloses a purification system for coke oven gas, which relates to the technical field of coke oven gas. Collector; the outlet ports of the second fine-stripping tower and the third fine-stripping tower are all connected with a reflux purifier, and the outlets of the two backflow purifiers are respectively connected with the first fine-stripping tower and the described first fine-stripping tower. The inlet end of the second fine stripping tower is connected; and the reflux purifier is provided with an intermittent opening and closing mechanism, and the intermittent opening and closing mechanism is used for intermittently controlling coke oven gas to flow back into the fine stripping tower through the corresponding reflux purifier. The present invention realizes the circulation treatment and purification effect of coke oven gas through the backflow purifier; and realizes the effect of opening and closing the backflow purifier through the intermittent opening and closing mechanism along with the rotation of the rotating base; at the same time, after driving the coke oven gas to rotate Enter the corresponding fine stripping tower to significantly improve the mixing efficiency and uniformity of coke oven gas.
Description
technical field [0001] The invention relates to the technical field of coke oven gas, more specifically it relates to a purification system of coke oven gas. Background technique [0002] Coke oven gas is a by-product of the coking process and is H 2 、CH 4 , CO 2 , CO and other gases, coke oven gas is a kind of high calorific value gas, which can be used as fuel, and can also be used as an important raw material for chemical products, such as synthetic ammonia, methanol, etc. Sulfur in the high-temperature coking raw materials enters the coke oven gas in the form of gaseous sulfides during the coking process. Among them, H 2 S, CS 2 , COS and other forms exist. The content of organic sulfide is less, and almost all of them are converted into H at high temperature 2 S, so hydrogen sulfide in gas is the main sulfide in coke oven gas. [0003] The patent with the notification number CN211814296U discloses a coke oven gas fine desulfurization system, which includes an oi...
