The heat transfer coefficient of the aluminum foil paper is high so that heat on one side can be well transmitted to the other side, it can be guaranteed that the whole pressure pipe is heated, and the pressure pipe is prevented from being frozen. According to the uniformly-heated instrument pressure pipe structure for the hydrogen or carbonic oxide delivery pipeline, a method for laying heat tracing belts on both sides of the pressure pipe is not needed, and inconvenience and large labor and heat tracing belt consumption which are caused by the method for laying the heat tracing belts on both sides of the thin and small pressure pipe can be effectively avoided.
Description
Technical field
The present invention relates to a kind of connecting pipe heating device, defeated more particularly, to a kind of hydrogen being heated evenly or carbon monoxide
Send pipeline meter pilot tubular construction.
Background technology
HyCO is hydrogen+carbon monoxide (Hydrogen+CO).The HyCO of narrow sense is while producing hydrogen and carbon monoxide
Chemical process.As carbon monoxide is all with hydrogen under normal circumstances while producing, therefore people use in gas industry
HyCO come represent major product be hydrogen and/or carbon monoxide and/or hydrogen, carbon mono oxide mixture (synthesis gas, or
Syngas chemical production device) or production technology.
By pipeline, downstream client supplies CO products and hydrogen product to HYCO devices, conveys in CO products and hydrogen product
During need to detect the quality of CO products and hydrogen product, accordingly, it would be desirable to convey in CO products and hydrogen product
Used in journey, connecting pipe is sampled analysis, and connecting pipe one end is directly connected on the pipeline of conveying CO products or hydrogen product,
Other end connecting detection instrument, needs to be incubated connecting pipe in detection, and existing operation is laid outside connecting pipe
Electric-heating belt.
Chinese patent CN105987830A discloses a kind of side for improving HYCO factories CO On-line Product precisions of analysis
Method, the method adopt probe tube on-line period, and described probe tube is electric tracing umbilical, and the electric tracing umbilical includes at least one
The heat-insulation layer of sample conveying tube, the electric-heating belt being arranged on by sample conveying tube, parcel sample conveying tube and electric-heating belt, and
The restrictive coating being coated on outside heat-insulation layer.The quantity of described sample conveying tube is one or two, the sample conveying tube outer cladding
There is a heat-reflecting layer.The material adopted by described heat-reflecting layer is copper aluminium polyester belt.Described electric-heating belt is Self-controlled electricity
Heating tape.The material adopted by described heat-insulation layer is non-hygroscopic glass fibre.
But as electric-heating belt relatively thin, connecting pipe is also relatively thin, when laying, electric-heating belt effectively can not be touched very well
Connecting pipe, so result in connecting pipe can only one side by temperature, it is impossible to allow well the whole connecting pipe face of cylinder by temperature, affect which to protect
The electrically heat tracing performance of temperature, it is final to affect instrument to use.And the heat-insulation layer in above-mentioned patent functions only as the work of insulation with restrictive coating
With, can not solve the problems, such as sample conveying tube one side by temperature with by warm uneven.
Chinese patent CN205716204U discloses a kind of jet chimney instrument connecting pipe heat tracing structure, including welds short
Pipe, stop valve, crossover sub, connecting pipe, transmitter, jet chimney, weld nipple one end be connected with jet chimney, the other end and
Stop valve connects, and stop valve is connected by crossover sub with connecting pipe, and connecting pipe other end connection transmitter, connecting pipe are U-shaped
Structure, U-shaped bottom pipe section press close to be arranged in parallel with jet chimney.Above-mentioned jet chimney instrument connecting pipe heat tracing structure is more
Complexity, and setup cost is high, takes up room big.
