At present, the main heat exchange media of trichlorosilane include water heat exchange and oil heat exchange. Due to the structure of the synthesis furnace, the heat exchange tube in the furnace is continuously washed by the hydrogen chloride gas carrying with the silicon powder particles under the condition of high temperature in the use process, the heat exchange tube is damaged after long-term use, the cooling medium in the heat exchange tube leaks into the synthesis furnace, and the heat exchange medium is water or oil, so that the safety production, the product quality, the equipment and the production efficiency are greatly influenced. Because the inside of the synthesis furnace is in a totally-enclosed and high-temperature state during the operation of the synthesis furnace, the using condition of the heat exchange tube in the furnace can be effectively detected, and the leakage of the heat exchange tube of the synthesis furnace can be prevented.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a synthetic furnace heat exchange tube that can detect and prevent to leak is provided, and this kind of heat exchange tube can carry out real-time effective detection to can prevent when the heat exchange tube from taking place to damage that heat transfer cooling medium from leaking to the stove in, provide the reserve time for the maintenance heat exchange tube, thereby guarantee safety in production, improve product quality and production efficiency.
The technical scheme for solving the technical problems is as follows:
a synthetic furnace heat exchange tube capable of detecting and preventing leakage comprises an inner tube and an outer tube, wherein the inner tube is sleeved in an inner cavity of the outer tube, one end of the inner tube is provided with a cooling medium inlet, one end of the outer tube is provided with a cooling medium outlet, the synthetic furnace heat exchange tube further comprises a detection sleeve and a detection instrument, the detection sleeve is sleeved outside the outer tube, a gap is formed between the inner wall of the detection sleeve and the outer wall of the outer tube, a detection port is formed in the tube wall of the detection sleeve, and the detection instrument is installed on.
Above-mentioned synthetic furnace heat exchange tube that can detect and prevent to leak, there is the connecting pipe on the detection sleeve's the detection mouth, and the connecting pipe is perpendicular with the detection sleeve, and the lower extreme and the detection sleeve's of connecting pipe detection mouth welded connection have a flange to seal the upper end of connecting pipe, and instrumentation connects on flange.
The utility model has the advantages that:
the utility model discloses having increased the detection sleeve pipe in current heat exchange tube outside, having gapped between detection sleeve pipe inner wall and the outer tube outer wall, having the detection mouth on the detection sleeve pipe wall, instrumentation installs on the detection mouth. When the heat exchange tube leaks, the leaked gas enters a gap between the detection sleeve and the outer tube of the heat exchange tube, the detection instrument can detect the leaked gas through the detection port and send out an alarm in time, and meanwhile, the leaked gas is sealed in a cavity between the detection sleeve and the outer tube and cannot leak to the external environment, so that time is won for maintaining and replacing the damaged heat exchange tube. The utility model discloses can utilize current heat exchange tube to reequip, practice thrift the expense and reduce manufacturing cost.
The utility model discloses simple structure, convenient to use can carry out real-time detection effectively, have reduced the equipment facility damage that causes because of heat transfer medium leaks, avoid having guaranteed security, continuity and the stability of production because of the influence of synthetic furnace heat transfer pipeline leakage to product quality, have improved production efficiency, have apparent economic benefits.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The figures are labeled as follows: the device comprises an inner pipe 1, an outer pipe 2, a detection sleeve 3, a detection port 4, a connecting pipe 5, a connecting flange 6, a detection instrument 7, a cooling medium inlet 8 and a cooling medium outlet 9.
Detailed Description
