Meanwhile, the methanol, fusel and hydrocarbon substances in the waste gas cause great pollution to the environment and endanger public safety due to the unorganized emission and leakage of the waste gas caused in the methanol filling process. For this reason, it is necessary to collect the off-gas from the methanol filling station and achieve an efficient treatment effect.
However, in the current exhaust gas treatment systems, the water absorption system, the adsorption condensation recovery system and the catalytic combustion treatment system are mainly used for treating the methanol exhaust gas. The main pollutants in the waste gas of the methanol filling station contain trace fusel and hydrocarbon substances besides methanol, a water absorption system is singly adopted, the solubility of the trace fusel in the waste gas is unknown, and meanwhile, the hydrocarbon substances cannot be dissolved in water, so that an ideal treatment effect cannot be achieved. In the adsorption condensation recovery system, the methanol waste gas generated by the methanol filling station is relatively less, the recovery benefit is lower, the cost of the adsorption condensation recovery device is high, and the operation cost is higher, so that the adsorption condensation recovery system has the defects. The catalytic combustion treatment system is suitable for treating organic waste gas with large air quantity and low concentration, and because the waste gas quantity generated by the methanol filling station is relatively small, a large amount of combustion-supporting gas needs to be supplemented during operation, high energy consumption and secondary pollution are easily caused, and meanwhile, the investment and operation cost of catalytic combustion equipment have the defect of overhigh cost for treating waste gas with small air quantity. Above-mentioned methanol filling station's exhaust treatment system has the structure to set up unreasonable and handles the problem that purification process easily causes secondary pollution, and exhaust treatment efficiency is unsatisfactory moreover, can't satisfy the user demand of current chemical industry processing.
