Abstract

The invention discloses a flare gas washing device mainly consisting of a water feeding system, a washing system and an overflowing system, wherein the water feeding system communicates with the top of the washing system via a pipeline, and the overflowing system communicates with the bottom of the washing system via the pipeline; the washing system is mainly composed of a spraying distributor, a vertical flare gas pipe, a vertical washing tank and a sealing water body; the spraying distributor, the vertical flare gas pipe and the sealing water body are all arranged in the vertical washing tank; the spraying distributor is arranged at the top of the vertical washing tank; the sealing water body is arranged at the bottom of the vertical washing tank; the vertical flare gas pipe is arranged below the spraying distributor and above the sealing water body; the upper end of the vertical flare gas pipe is fixed on the tank wall of the vertical washing tank; and the lower end of the vertical flare gas pipe is inserted into a water seal liquid level of the sealing water body. The device can achieve automatic recycling of the flare gas, prevent flashback, and achieve the purpose of thoroughly removing dust and impurities in the flare gas, so tat safety and reliability of a gas holder are improved.

Description

technical field [0001] The invention belongs to the field of discharge and recovery of combustible gas in petrochemical enterprises, and in particular relates to a torch gas water washing device. Background technique [0002] The combustible gas discharge and recovery system of petrochemical enterprises is an important measure to ensure the safe production of process equipment and environmental protection and energy-saving measures. When the process equipment is in normal production, the flare gas enters the gas cabinet facility for recovery as much as possible, and then sends it to the desulfurization device through the compressor After desulfurization, it is used as fuel gas in the factory to achieve the purpose of energy saving and emission reduction; when the flare gas discharged does not meet the gas cabinet intake requirements (temperature, pressure, flow exceeds the limit) under the accident conditions of the process equipment, it will be discharged to the flare gas of...
