Embodiment Construction

[0028] Such as figure 1 The multi-component organic waste gas safety treatment device shown has a multi-component organic waste gas collection device, an adsorption regeneration device, a water-cooled heat exchanger, and a gas-oil-water separation device in sequence according to the waste gas flow; three pipelines are connected after the gas-oil-water separation device. They are the non-condensable organic waste gas pipeline, the waterway and the oilway, and the waterway and the oilway are respectively connected to the collection device. The adsorption regeneration device is connected with a vacuum suction device to assist the desorption regeneration process.

[0029] An oxygen concentration detector and a double-branch control valve are installed at the outlet of the non-condensable organic waste gas pipeline. One catalytic oxidation branch is connected to the catalytic oxidation reactor; the other suction branch is connected to the inlet of the adsorption regeneration device...

Abstract

The invention provides a safe treatment device for a multi-component organic waste gas. The safe treatment device comprises a multi-component organic waste gas collection device, an adsorption and regeneration device, a water cooled heat exchanger and a gas-oil-water separation device in sequence, and is connected, behind the gas-oil-water separation device, with three pipelines, wherein the threepipelines are a non-condensable organic waste gas pipeline, a water way and an oil way respectively; an outlet of the non-condensable organic waste gas pipeline is provided with an oxygen concentration detector and control valves for double branches; one of the double branches is a catalytic oxidation branch; the other of the double branches is a resorption branch. The safe treatment device is used for guaranteeing that an explosive dangerous accident cannot occur in a catalytic oxidation reaction kettle and condensed oil with utilization value is recovered.

Description

technical field [0001] The invention relates to the treatment technology of organic waste gas. Background technique [0002] Volatile organic compounds (VOCs) generally refer to the general term for organic compounds with a saturated vapor pressure > 70Pa and a boiling point < 260°C at normal temperature and pressure, including aliphatic hydrocarbons, aromatic hydrocarbons, halogen-containing hydrocarbons, oxygen-containing hydrocarbons, and Nitrogenous hydrocarbons and sulfur-containing hydrocarbons, etc. VOCs are serious hazards to the ecological environment and human health. VOCs can cause human carcinogenicity, teratogenicity, and animal and plant poisoning. They can react photochemically with NOx under sunlight, which is one of the reasons for photochemical smog. [0003] There are many kinds of VOCs and they are widely distributed. They mainly come from many industries and departments such as petroleum, chemical industry, light industry, etc. Some industries suc...
