Abstract

The invention discloses a coking VOCS tail gas treatment device. The invention relates to the field of coking VOCS tail gas treatment. The device comprises a gas conveying pump, a gas inlet pipe, a buffer tank, a washing mechanism, a water seal tank, a gas-liquid separator, a preheating mechanism, a flame arrester and a catalytic oxidation furnace, a washing air inlet pipe is arranged between thebuffer tank and the washing mechanism, the washing mechanism comprises a washing tower, a washing assembly and a filtering assembly, a washing gas outlet pipe is arranged on the upper portion of the washing tower, a separation pipe is arranged between the water seal tank and the gas-liquid separator, a preheating gas inlet pipe is arranged between a gas-liquid separation tank and the preheating mechanism, and a preheating gas outlet pipe is arranged between the preheating gas inlet pipe and the catalytic oxidation furnace. Washing waste gas washing oil is filtered in time through the filteringassembly, impurities in the washing oil are reduced, the washing oil recycling frequency is increased, then washing oil consumption is reduced, the cost is reduced, secondary pollution caused by thewashing oil to the environment is avoided, energy of substances in waste gas is fully utilized, and the purposes of energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the field of coking VOCS tail gas treatment, in particular to a coking VOCS tail gas treatment device. Background technique [0002] The tail gas in the refining process of crude benzene in the coking plant mainly includes: waste gas from process equipment in the process of deep processing of crude benzene, waste gas from tank farms in product storage, and waste gas from loading and unloading. The components of the exhaust gas are complex, containing not only toxic carcinogens such as benzene, toluene, xylene, asphalt fume, benzopyrene, but also malodorous substances such as hydrogen sulfide and ammonia. [0003] The existing tail gas treatment devices in my country include fans, absorption towers and discharge cylinders. The tail gas in the crude benzene refining process of the coking plant is first sucked by the fan to the lower part of the absorption tower, and most of the benzene substances contained in the waste gas are ab...
