The utility model palladium-pipe hydrogen exhausting apparatus, described palladium tube adopt Metal Palladium or palldium alloy to make.
This device is the tubular metal container made from palladium or palldium alloy by the electric heater heating, contain and have only hydrogen outside palladium or palldium alloy pipe, to see through tube wall in pipe in the mist of hydrogen, by cross-ventilation, be discharged in the atmosphere again, thus the performance of assurance lithium-bromide absorption-type refrigerating machine group.
Description of drawings
Fig. 1 is the general structure schematic diagram of the utility model palladium-pipe hydrogen exhausting apparatus.
Fig. 2 is the A-A cut-away view of Fig. 1.
Among the figure: palladium tube 1, mist import 2, cylindrical shell 3, matrix 4, electric heater 5, supply line 6, AC power 7, temperature element 8, cylinder type sheath 9, protection tube 10, groove 3.1.
The specific embodiment
Referring to Fig. 1～2, the utility model palladium-pipe hydrogen exhausting apparatus mainly is made up of cylindrical shell 3, matrix 4, palladium tube 1 and electric heater 5.The sealing of cylindrical shell 3 one ends also is provided with mist import 2; the other end inserts matrix 4 and sealing; matrix 4 near in the middle of mist import 2 ends to away from mist import 2 ends axially grooved 3.1; palladium tube 1 radially is set in the groove 3.1; palladium tube 1 both ends open, palladium tube 1 two ends carry out vacuum brazing with the barrel of cylindrical shell 3 or gas protecting soldering is connected.Insert electric heater 5 in the matrix 4 of palladium tube 1 both sides, electric heater 5 adopts the single-ended electric heater 5 of column type, and electric heater 5 links to each other with AC power 7 by supply line 6.The heat of the generation of electric heater 5 can be fast by matrix 4 and is passed to palladium tube 1 uniformly.Temperature element 8 is set in matrix 4, and temperature element 8 links to each other with the control system (not shown), by control system palladium tube 1 is carried out temperature control.Be overmolding to cylinder type sheath 9 at cylindrical shell 3 external application insulation materials, to avoid thermal loss.At palladium tube 1 two ends protection tube 10 is set, protection tube 10 stretches out outside the cylinder type sheath 9, and protection tube 10 can be protected palladium tube 1, and the double as passage, is used for the hydrogen discharge that sees through to atmosphere.The hydrogen of also being more convenient for is diffused in the atmosphere and goes.
Contain in the mist import 2 importing cylindrical shells 3 of mist by cylindrical shell 3 one ends of hydrogen, mist contacts with palladium tube 1 outer wall, AC power 7 is passed to electric heater 5 by supply line 6, palladium tube 1 is heated, when palladium tube 1 temperature rises to 300～400 ℃, the hydrogen that contains in the hydrogen mixed gas in the closed cavity that palladium tube 1 outer wall and cylindrical shell 3 inwalls form is discharged in the pipe through tube wall outside palladium tube by the electric heater heating, by cross-ventilation, is diffused in the atmosphere again.
The material of cylindrical shell 3, its thermal coefficient of expansion is close with palladium tube 1.
The setting of palladium tube 1 is not limited to one, can be provided with two or many according to the needs of hydrogen discharge capacity.
The installation of palladium-pipe hydrogen exhausting apparatus, for the hydrogen that makes discharge is diffused in the atmosphere faster by cross-ventilation, also poor in order effectively to increase palladium tube 1 inside and outside hydrogen partial pressure, palladium tube 1 installation direction should be vertical with cylindrical shell 3 axis directions.
