Embodiment Construction

[0016] A vehicle-used coke oven gas desulfurization device, the coke oven gas gas inlet pipe 1 and the air inlet pipe 2 communicate with the lower part of the desulfurization tower 11 through the three-way interface A3, the stop valve A4 and the pressure gauge 5, and the top of the desulfurization tower 11 is provided with a gas outlet , the gas outlet at the top of the desulfurization tower 11 is connected to the tee pipe B13 through the stop valve B12, and one end of the three-way pipe B13 is connected to the recovery tank 15 through the stop valve C14. Fine desulfurizer 10. A heating device 6 is provided at the bottom of the desulfurization tower 11 .

[0017] After the coke oven gas containing impurities such as hydrogen sulfide enters the coke oven gas vehicle filling station, it needs to enter the desulfurization tower for desulfurization treatment. The coke oven gas enters through the intake pipe 1, mixes with the air entering from the intake pipe 2 at the three-wa...

Abstract

The invention discloses a desulfurization process for a coke-oven gas automobile gas station. The desulfurization process is characterized by comprising the primary rough desulfurization process and the secondary fine desulfurization process. According to the desulfurization process for the coke-oven gas automobile gas station, coke or activated carbon is used as a rough desulfurization agent for removing a small amount of organic sulfur out of the coke-oven gas and absorbing hydrogen sulfide in a primary desulfurization tower, and a fine desulfurization agent composed of iron oxide hydrates is used for removing the hydrogen sulfide through chemical reactions in the secondary desulfurization tower. The desulfurization process is simple, high in accuracy, capable of achieving continuous regeneration and suitable for desulfurization purification for the large-scale automobile coke-oven gas, the activated carbon resources and the iron oxide resources are abundant and low in price, therefore, the production cost can be greatly saved, and popularization is facilitated.

Description

technical field [0001] The invention relates to a desulfurization process of coke oven gas, in particular to a desulfurization process of coke oven gas vehicle filling station and a device thereof. Background technique [0002] Nowadays, the number of automobiles in our country is increasing day by day, and the problem of lack of oil resources is gradually revealed. Coke oven gas is a combustible mixed gas obtained from coke and tar products after the raw coal is isolated from the air and high-temperature dry distillation in the coke oven. It is the main by-product of the coking industry and can be used as an alternative fuel for vehicles. The hydrogen sulfide gas contained in the coke oven gas will cause corrosion in the combustion chamber of the automobile engine, excessive wear of the valve and damage to the seal, and it will also cause coking problems. Gaseous SO from sulfur combustion 2 It is discharged into the air and converted into secondary sulfate particles, whos...
