Abstract
The raw gas regenerating process to prepare high quality gas includes the following steps: partially burning the coking oven raw gas containing great amount of water vapor and tar vapor with added oxygen directly without cooling; the water gas reaction of the burnt product in a filter to obtain regenerated gas with H2 and CO as main components; purification of the regenerated gas in a dedusting system to obtain purified regenerated gas; and conveying the purified regenerated gas with a Roots blower into gas storage for supplying to the consumer. The partial burning of raw gas can reach gas temperature as high as 1100 deg.c. The present invention has the advantages of short process, compact apparatus, less pollution, no liquid waste produced, high gas product purity, etc.
Description
(1) technical field:
The present invention relates to a kind of raw gas makes with H under high temperature action
2, CO is the method for main synthetic high-quality regeneration coal gas.
(2) technical background:
The ordinary method of handling coal oven dithio-gas is: 650 ℃-850 ℃ raw gas is cooled to 80 ℃-85 ℃ at bridge tube, effuser spray ammoniacal liquor, be cooled to 25 ℃-35 ℃ again in gas primary cool workshop section, a large amount of sensible heat and wherein a large amount of water vapour, the latent heat of tar steam of raw gas is wasted during this time, also need to consume a large amount of water coolants and ammonia simultaneously, coal gas after just cold also will pass through electrically trapped tar oil, removes ammonia, take off operations such as naphthalene, desulfurization, is purified coal gas and could generates synthetic gas as raw material.All there is coking chemical waste water to produce in each workshop section, also has coke tar refuse and regenerating wash oil residue to generate in addition, when big energy is wasted, cause very big environmental pollution.
(3) summary of the invention:
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of raw gas regenerating process to prepare high quality gas, this method not only can directly be utilized 650 ℃-850 ℃ the sensible heat of raw gas and the latent heat of its little steam, and be rich in a large amount of high-energy active particle and participate in chemical reaction, can generate purity higher, be rich in CO and H
2High-quality coal gas.
The technical scheme that adopts is:
Raw gas regenerating process to prepare high quality gas is characterized in that it being to comprise following technological process:
The raw gas that contains a large amount of water vapour and tarry vapours that pit kiln is generated is without cooling process, directly enter strainer after the oxygenation partial combustion, and water-gas reaction takes place in strainer, it is the regeneration coal gas of hydrogen and carbon monoxide that the reaction back obtains major ingredient, the regeneration coal gas that is obtained purifies through dust-removal system and obtains purified regeneration coal gas, at last purified regeneration coal gas is sent in the gas tank by roots blower again and stored, use for the user.
Above-mentioned adding oxygen partial combustion in raw gas, gas temperature reaches 1100 ℃.
It is short that the present invention has flow process, facility compact, pollute little, the absence of liquid refuse produces, coal gas purity advantages of higher.
(4) description of drawings
Fig. 1 is a process flow sheet of the present invention.
(5) embodiment
The coking raw gas mainly consist of water vapour 30-36%, CH
417%-31%, tar steam 9%-14%, CO7%-12%, H
24%-10%, CO
22%-7%, N
21%-10%, crude benzol 2.5%-4.3%, ammonia 0.7%-1.1%.From above-mentioned composition as can be seen, raw gas contains a large amount of water vapour, tar steam, CO and CO
2
Raw gas regenerating process to prepare high quality gas of the present invention be raw gas that pit kiln is generated without cooling process, directly be incubated, and be blown into oxygen and make it partial combustion and reach 1000 ℃, then this gas is sent in coke, the Wingdale strainer CO in the raw gas
2, H
2O generates CO and H through reacting with C
2, the regeneration coal gas major ingredient that obtains through reaction is hydrogen and carbon monoxide, and takes off S, obtains purified regeneration coal gas behind gravitational dust collection and bag-type dust through lime, the regenerated coal gas after the purification is sent in the gas tank by roots blower and is used for the user.
Claims (2)
1, raw gas regenerating process to prepare high quality gas, it is characterized in that it being to comprise following technological process: the raw gas that contains a large amount of water vapour and tarry vapours that pit kiln is generated is without cooling process, directly enter strainer after the oxygenation partial combustion, and water-gas reaction takes place in strainer, it is the regeneration coal gas of hydrogen and carbon monoxide that the reaction back obtains major ingredient, the regeneration coal gas that is obtained purifies through dust-removal system and obtains purified regeneration coal gas, at last purified regeneration coal gas is sent in the gas tank by roots blower again and stored, use for the user.
2, raw gas regenerating process to prepare high quality gas according to claim 1 is characterized in that the described oxygen partial combustion that adds in raw gas, gas temperature reaches 1100 ℃.
