Description
The present invention relates to a kind of employing and fill the hydrogen aerator of hydrogen material.
Metallic material in manufacture process (as smelting, pickling, heat treatment, electrolysis or plating etc.) in absorb the hydrogen of more amount or at ambient containing hydrogen (as hydrogen, hydrogen sulfide, hydrogen cloride or various hydrocarbons etc.) in when using, changes of properties often appears, mainly showing as plasticity reduces, be called " hydrogen embrittlement ", research hydrogen is important topic in the materials science to various metallic material Effect on Performance and mechanism thereof, metallic material is placed on different temperatures, certain hour in the hydrogen of different pressures, make hydrogen enter material internal, take out then that to carry out various tests are one of methods of research material hydrogen performance, high-pressure, high purity and hot hydrogen aerator fills the employed special device of hydrogen to material exactly, major requirement to this device is: the purity of (1) hydrogen wants high, fitness for purpose 99.999% to 99.9999%; (2) reach certain pressure, as required, do not wait by several barometric pressure to a hundreds of barometric pressure.
The at present external device that adopts mostly is with bottled hydrogen through catalysis, molecular sieve adsorption or cryogenic absorption to reach the purpose of purifying, is pressurized to required pressure with moulding press again, and the shortcoming of this method is:
(1) purity of hydrogen is the highest can only reach 99.999%;
(2) purification system complexity is kept low temperature and will be consumed a lot of energy;
(3) the molding machine noise is big, the huge costliness of whole system, easy leakage, maintenance difficult, running expense height, though utilize palladium tube stove purifying can reach 99.9999% purity, but efficient is very low, and produces secondary pollution inevitably in pressure process subsequently, needs purifying once more after the pressurization.
For solving above deficiency, purpose of the present invention provides a kind of high-pressure, high purity and hot hydrogen aerator, and it utilizes the principle of chemical reaction, reaches the purpose to hydrogen purifying and pressurization simultaneously, has removed purifying and pressurization device from, has effectively solved to store hydrogen and with the problem of hydrogen.
Technological scheme of the present invention is design like this: structure of the present invention is by high-purity hydrogen source still, High Temperature High Pressure hydrogen charging kettle, connecting pipeline between two or more normal temperature high voltage hydrogen charging kettles and each still is formed, and sets up and is furnished with vacuum unit and electric control system (shown in Fig. 1～4).Concrete structure is that the former still of High Purity Hydrogen is the core component in the hydrogen aerator, and it will utilize hydrogen storage material LaNl
5The H-H reaction (LaNl of reversible suction hydrogen
5+ 3H
2=LaNl
5H
6) temperature effect (LnPH of balance pressure
2=A+-) (only a large amount of hydrogen of inhaling, impurity then is enriched in LaNl in the hydrogen with selecting absorption characteristic
5In particle surface and the gap, at first discharged when putting hydrogen), the purifying of hydrogen and one step of pressurization are finished.There is oven high-purity hydrogen source still outside by kettle, kettle cover, inside, and pressure gauge is arranged at the top, and thermocouple, fairlead and filter are formed, and LaNl is housed in the still
517.5 kilogram (its structure is by shown in Figure 1).LaNl is housed in the middle of the high pressure hydrogen source still
5, the outside is an oven, is heated by electrical control, and thermocouple is housed in the still, Gai outlet thereon is added with filter, and pressure gauge is housed simultaneously; High Temperature High Pressure hydrogen charging kettle and high-purity close connection of hydrogen source still are not put LaNl in the hydrogen charging kettle
5Material has heating apparatus, has pressure interface to communicate with the outside; Normal temperature high voltage hydrogen charging kettle on two, have only pipeline to communicate with the hydrogen source still, wherein the High Temperature High Pressure hydrogen charging kettle all links to each other with high-purity hydrogen source still with pipeline with two tool normal temperature high voltage hydrogen charging kettles, respectively carries control valve, and the normal temperature high voltage hydrogen charging kettle can connect two or more according to the difference of pressure or purposes.
Its working procedure: high-purity hydrogen source still LaNl that packs into
5After, throw vacuum earlier, feeding pressure again is 10～100kgf/cm
2Bottled hydrogen, make LaNl
5Inhale saturated (the about 180ml H of hydrogen
2/ gLaNl
5).Emit 10% hydrogen then, foreign gas is discharged, the high pressure hydrogen charging kettle is packed into and is vacuumized behind the sample of preparing to fill hydrogen, the hydrogen source still is warmed up to required temperature, after hydrogen pressure being reached give the fixed number value, hydrogen is imported the high pressure hydrogen charging kettle, begin sample is filled hydrogen, after finishing, each experiment the hydrogen source still is cooled off LaNl wherein
5Can use repeatedly.
The top cover of hydrogen source still has the hole of two φ 8, is furnished with filter, LaNl when preventing to put hydrogen
5Powder is taken out of with air-flow.Hydrogen Vapor Pressure is by control LaNl
5Temperature regulate, the hydrogen source still being discharged 10% hydrogen before heating is that the purity that guarantees hydrogen reaches 99.9999% necessary condition.
The present invention has compared following advantage with foreign technology: by material LaNl
5The air-breathing characteristic of selection, so do not need purification plant, by control LaNl
5Temperature regulation pressure, so do not need compressor, the purity of hydrogen can reach 99.9999%, noiseless, simple in structure, advantage such as power consumption is few.
