Gas-liquid separator for high freezing point medium with labyrinth inlet pipe insulation device

Abstract

The invention relates to the technical field of gas-liquid separation equipment in chemical plants, in particular to a high-freezing-point medium gas-liquid separator with a labyrinth-type intake pipe heat preservation device. It includes an elliptical head, a cyclone cylinder and a cyclone cone from top to bottom; the ellipse head, cyclone cylinder, cyclone cone, liquid discharge pipe and exhaust pipe located outside the ellipse head are all equipped with insulation cover, forming a thermal insulation cavity, and connecting round pipes are provided between adjacent thermal insulation cavities; a tangential air intake pipe is provided on one side of the cyclone cylinder, and the tangential air intake pipe includes an air intake pipe, Tapered pipe and rectangular pipe, the four sides of the tapered pipe are respectively provided with a tapered pipe insulation chamber, and the four sides of the rectangular pipe are respectively provided with a rectangular pipe insulation chamber; the heat transfer oil enters from the heat transfer oil inlet of the intake pipe, passes The insulation cavities on the four sides of the tapered tube, the circular tube insulation cavity and the four sides of the rectangular tube flow out from the heat transfer oil outlet of the intake pipe at last.

Description

technical field [0001] The invention relates to the technical field of gas-liquid separation equipment in chemical plants, in particular to a high-freezing-point medium gas-liquid separator with a labyrinth-type intake pipe heat preservation device. Background technique [0002] At present, there are generally gas-liquid separation equipment in chemical plants. The gas-liquid mixture enters the equipment through the tangential inlet pipe, and the separation of gas and liquid is achieved through the cyclone centrifugal force formed inside the equipment. However, at present, the gas-liquid separation equipment mainly has the problem that the medium with high freezing point is easy to freeze during the intake process, and sticks and blocks inside the equipment and the intake pipe, resulting in the failure of the equipment function. Therefore, the medium with high freezing point needs to be fed in the gas-liquid separation Before preheating, preheating generally uses special hea...
