A pipeline preheating device

Abstract

The invention relates to a pipeline preheating device, which includes a heat exchange area for heat exchange of high-temperature heat sources, a heat preservation area for the flow of hot and warm heat sources, a connecting mechanism connecting the heat exchange area and the heat preservation area, and an inner pipe clamping mechanism; The mechanism includes a hollow flow tube, wherein the front end of the flow tube is a heat exchange area, an annular water injection shell is arranged on the outer wall of the front end of the flow tube, and a number of water inlet grooves are arranged in an annular array on the wall surface of the flow tube, and the inner wall of the flow tube The position corresponding to the water inlet tank is provided with a diversion heat exchanger; the inner pipe clamping mechanism includes an inner pipe sleeve A, and the front end of the inner pipe sleeve A is provided with a flange A, which is fixed between the flange A and the end of the flow pipe. Connection, the outer wall of the inner sleeve A is in contact with the heat conduction support column; the heat preservation area includes a water storage tank located on the inner wall of the other end of the flow tube, and an annular guide ring made of porous material is arranged at the opening of the water storage tank; the inner pipe clamp The holding mechanism also includes an inner sleeve B, and a flange B is arranged at the rear end of the inner sleeve B.

Description

technical field [0001] The invention relates to pipeline preheating equipment, which belongs to the field of pipeline heat preservation equipment. Background technique [0002] For long-distance factory pipelines, it is easy to freeze in the north, and if only the liquid input in the pipeline is heated, then as the temperature gradient decreases, it is still easy to freeze in the second half of the pipeline, so almost There is a need for a mechanism that has a simple structure and can perform heat exchange and heating on the pipeline to achieve heat preservation and heating of each node. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pipeline preheating device by overcoming the technical problem of difficulty in heating and keeping long pipelines in the prior art. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A pipeline preheating equipment, inc...
