High-freezing-point medium gas-liquid separator with labyrinth-type gas inlet pipe heat-preserving device

Abstract

The invention relates to the technical field of gas-liquid separation devices in chemical engineering equipment, specifically to a high-freezing-point medium gas-liquid separator with a labyrinth-typegas inlet pipe heat-preserving device. The high-freezing-point medium gas-liquid separator successively comprises an elliptical seal head, a cyclone drum body and a cyclone cone body from top to bottom, wherein the elliptical seal head, the cyclone drum body, the cyclone cone body, a liquid discharging pipe and an exhaust pipe located at the exterior of the elliptical seal head are respectively sleeved by a heat-preserving sleeve to form heat-preserving cavities; a connecting circular pipe is arranged between adjacent heat-preserving cavities; a tangential gas inlet pipeline is arranged at one side of the drum body of the cyclone drum body and comprises a gas inlet circular pipe, a cone pipe and a rectangular pipe; four side surfaces of the cone pipe are respectively provided with a conepipe heat-preserving chamber; and four side surfaces of the rectangular pipe are respectively provided with a rectangular pipe heat-preserving chamber. According to the invention, heat-conductive oilenters from the heat-conductive oil inlet of a gas inlet pipe, respectively passes through the heat-preserving chambers located on four side surfaces of the cone pipe, the circular pipe heat-preserving chamber and the heat-preserving chambers located on four side surfaces of the rectangular pipe, and finally flows out from the heat-conductive oil outlet of the gas inlet pipe.

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...
