Description

; f - The invention is mercury binding devices, and more specifically to pipe heating devices transporting heated fluid material. A device for heating a pipeline is known, comprising a steam jacket mounted on the pipeline and equipped with a steam trap KOMj operated by means of compressed air. The disadvantage of such a device is the need for a source of low air that ensures the operation of the steam trap. It is also known a device for heating a pipeline, comprising a sealed chamber, framing along the entire length of the pipeline, supply and outlet connections of the heat transfer body and end flanges mounted on the chamber. However, this device has significant heat loss and does not both ensure uniform heating of the pipeline, which leads to non-rapid transfer of heat to the flowable material transported through the pipeline. Object of the invention. Reduction of heat loss and improvement of heat transfer. The goal is achieved by the fact that in a device for heating a pipeline, including a sealed chamber, framed along the entire length of the pipe, supply pipes and exhaust pipes. heat carrier and end flanges mounted on the chamber, the latter is provided with a heat insulating sheath and is made with flat ribs fixed along a screw line relative to the axis of the pipeline on its inner side and formed with a pipe with ring holes. At the expense of the ribs, which are helically arranged inside the hermetic chamber, the directional movement of the heat transfer medium around the pipeline with its uniform heating throughout its length is provided, and the heat insulation sheath installed on the kilogram reduces heat losses to the environment. The drawing shows a device for heating the pipeline, the cut. The device 10 for heating the pipe line 1 consists of a sealed chamber 2 branch pipes | a 3 feeds and a branch pipe 4 discharging warmly mounted, mounted on the flanges 5 of the chamber 2. The latter is provided with a heat insulating sheath 6. and is made with flat ribs 7,

Fixed P6 Vent6 LNS from (relative to the axis of the pipeline 1 on its inner side and forming annular gaps 8 with the pipeline. The tightness of the chamber 2 is achieved due to the tight connection of the flanges 15 with the pipeline 1.

The device works as follows: - -::.

The 3 ndSaiH pipe connects the heat source to its source. The heat carrier entering the cavity of chamber 2 flows through a screw channel formed by flat pillars 7 and partially through annular gaps 8, the surface of the pipeline 1 is uniformly heated in it. The spent heat carrier is removed through the nozzle 4. Due to the directed screwing of the Dissipation of the coolant in the heating chamber and its warm cooling, the heat transfer from the heat exchanger to the transportable pipe is improved.
