On top of the gas-storage chamber are disposed a self-closing valve and a spring non-return exhaust valve or a magnetic valve, or an electrically-operated valve.
Description
Technical field:
The present invention relates to a kind of automatic exhaust device and method, be specifically related to a kind of vacuum pump less automatic exhaust device and method of lithium bromide unit.
Background technology:
Though the lithium bromide unit can have automatic gas extraction device, but when internal gas is disposed to atmosphere, palladium tube or the oil-sealed rotary pumps of adopting are realized more, and palladium tube is a noble metal, cost an arm and a leg, can only take out hydrogen, can not take out other gas, unit can not be avoided refrigerating capacity to descend and be corroded when leaking.Vavuum pump then can be extracted the moisture of solution in the unit out with vapor form, these water vapours liquefy in vavuum pump, makes pumping fluid emulsification, if oilless vacuum pump then liquid hammer, cause pumping speed to descend, limiting pressure rises, even makes vavuum pump corrosion, stuck and burn-down of electric motor.
Summary of the invention:
Technical problem to be solved by this invention is: at above-mentioned the deficiencies in the prior art, and provide a kind of and need not palladium tube or vavuum pump, can realize that internal gas is disposed to atmosphere automatically, effectively simplifies set structure and increase the vacuum pump less automatic exhaust device and the method for the lithium bromide unit of operational reliability equally.
The technical solution used in the present invention is: the vacuum pump less automatic exhaust device of this lithium bromide unit includes automatic gas extraction device, aspirating chamber, gas-liquid separation chamber, gas dome, automatic gas extraction device is introduced aspirating chamber by air inlet pipe with incoagulable gas in the unit, aspirating chamber arrives gas-liquid separation chamber by exhaust tube with its injection again, the indoor gas of gas-liquid separation is by air guide, return the dual-purpose pipe connection of liquid and enter gas dome, the indoor solution of gas-liquid separation then returns unit inside by pipeline, the present invention is provided with valve F1 at the solution pump outlet conduit of lithium bromide unit, between solution pump and valve F1, draw the exhaust feed tube to gas dome, establish valve F2 between the exhaust feed tube, air guide between gas dome and gas-liquid separation chamber, return the dual-purpose pipe of liquid valve F3 is set, the gas dome top is provided with valve sets.
The valve sets that the gas dome top is provided with comprises glueballs blocking solution exhaust self-closing valve and spring non-return exhaust valve, and can increase magnetic valve or motor-driven valve, the valve body of glueballs blocking solution exhaust self-closing valve has the last conical surface and the following conical surface, and there is free suspension glueballs the centre, and glueballs density is less than solution.
In gas dome gas more for a long time, valve-off F1, F3 open valve F2, start solution pump, and solution is pressed into gas dome, the air storage indoor gas is compressed, it is a certain amount of to surpass atmospheric pressure, spring non-return exhaust valve is backed down, gas is discharged automatically; When gas drained, the glueballs of glueballs blocking solution exhaust self-closing valve come-up formed sealing with the last conical surface, prevents the solution ejection.If there is gas to enter glueballs blocking solution exhaust self-closing valve, solution is pushed back gas dome, and glueballs descends and the following conical surface forms sealing, prevents that gas from entering gas dome, finishes exhaust process; Valve-off F2 opens valve F1, F3, and solution forms vacuum chamber because of gravity falls after rise in the gas dome, and air storage again is convenient to automatic gas extraction device and is restarted to bleed.
The present invention utilizes existing solution and solution pump in the unit, by valve event, changes the flow of solution direction, and bromizates lithium unit automatic vent, does not need vavuum pump or palladium tube, simplifies set structure and increases operational reliability.The defective of avoided adopting palladium tube to cost an arm and a leg, can only take out hydrogen, can not take out other gases, unit leaking refrigerating capacity decline and corrosion, also avoided emulsification of employing pumping fluid or liquid hammer, pumping speed decline, limiting pressure rising, pump corrosion, stuck, burn problems such as motor, the present invention has effectively simplified set structure and has increased the unit operation reliability, has improved the machine set technology performance.
Description of drawings:
Fig. 1 is a structural representation of the present invention
Fig. 2 is a glueballs blocking solution exhaust self-closing valve structural representation of the present invention
The specific embodiment:
1. referring to Fig. 1, the vacuum pump less automatic exhaust device of this lithium bromide unit includes automatic gas extraction device, aspirating chamber, gas-liquid separation chamber, gas dome, automatic gas extraction device is introduced aspirating chamber by air inlet pipe 1 with incoagulable gas in the unit, aspirating chamber arrives gas-liquid separation chamber by exhaust tube 2 usefulness liquid stream injection, the indoor gas of gas-liquid separation enters gas dome by air guide, dual-purpose pipe 3 connections of time liquid, the indoor solution of gas-liquid separation then returns unit inside by pipeline 4, and accumulation gas needs to enter atmosphere more for a long time in the gas dome.
2. referring to Fig. 1, the present invention is provided with valve F1 at solution pump 5 outlet conduits of lithium bromide unit, between solution pump 5 and valve F1, draw exhaust feed tube 6 to gas dome, 6 of exhaust feed tubes are established valve F2, air guide between gas dome and gas-liquid separation chamber, time dual-purpose pipe 3 of liquid are provided with valve F3, and the gas dome top is provided with valve sets.Valve sets comprises glueballs blocking solution exhaust self-closing valve 7 and spring non-return exhaust valve 8, and can increase magnetic valve or motor-driven valve.
3. referring to Fig. 2, the valve body 12 of glueballs blocking solution exhaust self-closing valve 7 has the last conical surface 9 and the following conical surface 10, and there is free suspension glueballs 11 centre, and glueballs 11 density are less than solution.Spring non-return exhaust valve 8 relies on spring pressure that valve cuts out, and when the valve internal pressure surpassed spring pressure, valve was opened automatically, otherwise closes.
4. vacuum pump less automatic vent method: gas more for a long time in gas dome, valve-off F1, F3 open valve F2 and solution pump 5, and solution is pressed into gas dome, the air storage indoor gas is compressed, when Compressed Gas air pressure was a certain amount of above atmospheric pressure, spring non-return exhaust valve 8 was backed down, and gas is discharged automatically, when gas drains, solution forms sealing with the glueballs come-up of glueballs blocking solution exhaust self-closing valve with the last conical surface 9, prevents the solution ejection.If when the outside had gas to enter glueballs blocking solution exhaust self-closing valve, solution was pushed back gas dome, glueballs descends and the following conical surface 10 forms sealing, prevents that gas from entering gas dome, promptly finishes exhaust process; Valve-off F2 opens valve F1, F3, and solution forms vacuum chamber because of gravity falls after rise in the gas dome, and air storage again is convenient to automatic gas extraction device and is restarted to bleed.
