Treatment device for light hydrocarbon-containing petrochemical gas

Abstract

The invention relates to the technical field of treatment devices, in particular to a light hydrocarbon-containing petrochemical gas treatment device which comprises a supporting seat and a device shell, the device shell is fixedly mounted in the supporting seat, an annular groove is formed in the side wall surface of the device shell, a gas inlet pipe and an exhaust pipe are mounted on the two side surfaces of the device shell respectively, and a gas outlet pipe is mounted on the gas inlet pipe. The air inlet pipe and the air outlet pipe are symmetrically distributed with the circle center of the device shell as the center. Petrochemical gas enters the device shell from the gas inlet pipe, the gas moves downwards along a spiral channel formed by the inner wall of the device shell and the spiral blades, and liquid in the petrochemical gas moves downwards along the inner wall of the spiral channel and is gradually gathered and increased under the combined action of gravity and rotating centrifugal force; liquid can be discharged from the inside, and gas enters from the conveying channel and is discharged from the exhaust pipe, so that the separation of petrochemical gas is realized, the separation effect is good, and the use is relatively convenient.

Description

technical field [0001] The present application relates to the technical field of processing devices, and in particular, to a processing device for petrochemical gas containing light hydrocarbons. Background technique [0002] Liquefied petroleum gas—generally refers to a mixture of C1 to C4 hydrocarbons from petroleum systems. It may contain hydrogen and hydrocarbons with carbon five or more, as well as impurities such as sulfides. According to the source, it can be roughly divided into: (1) natural petroleum gas, such as natural gas and associated gas from oil mines; (2) by-product gas of petroleum processing, such as cracking gas and coking gas; (3) liquid petroleum product cracking gas (mainly generated gas) ). [0003] For example, a Chinese patent discloses: a processing device for petrochemical gas containing light hydrocarbons, publication number: CN209173639U, "By being provided with a gas alarm on the separation tank, the petroleum gas can be detected, and when th...
