Requirement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic block circuit diagram of the utility model.
Specific embodiment
As illustrated in fig. 1 and 2, the utility model includes air velocity transducer 6, air inlet pipe 10, intake valve 3, air outlet valve 9, outlet
Pipe 4, tee tube 7, purification air-source 11 and controller；The air velocity transducer 6 is fixed at 2 upper end of space division pure argon column
At gas outlet, the gas outlet of purification air-source 11 is connected by air inlet pipe 10 with the first air inlet pipe of tee tube 7, tee tube
Second air inlet pipe and an air outlet pipe is connected in existing nitrogen air inlet gas circuit, and intake valve 3 is arranged in air inlet pipe 4, and air outlet valve 9 is set
It sets on escape pipe 4, the input terminal of the output end connection controller of the air velocity transducer 6, the output end difference of controller
The control signal of intake valve 3 and air outlet valve 9 is connected, controller is connected with the power control terminal of space division pure argon column, for controlling
The start and stop of space division pure argon column processed.
It further include check-valves 8, the check-valves 8 is arranged at the gas outlet of tee tube 7.Room temperature can effectively be placed
Since pressure is backwashed, more preferable faster heat exchanging device is heated the air of purification.
It further include having delayed relay, controller is arranged in the delayed relay and the power supply of space division pure argon column controls
Between end on circuit.The start-stop time that can select space division pure argon column according to setting demand by setting delayed relay, also can
Giving more times makes its initialization.The intake valve and air outlet valve is to use flow throttling ball valves.Control is sensitiveer, fastly
It is prompt.
The heat exchanger 1 of the present apparatus is board-like heat exchanger, and top is provided with liquid nitrogen inlet 5, from the normal of space division system
Warm dirt nitrogen or dry air enter the scars in pure argon column, heat exchanger and heat exchanger (such as: solid argon, ice through air inlet pipe 4
Deng) come into full contact with；It to make scars melt, is taken out of by dirty nitrogen or dry air, is vented as exhaust gas.The invention reside in skies
Occur that humid air enters heat exchanger or because operation of heat exchanger temperature is too low, argon gas is cold before the debugging of point ar system or in debugging process
Cure blocks heat exchanger channel, when causing system debug product that design requirement is not achieved, is heated, is made to it by gas at normal temperature
System is restored normally quickly, wherein room temperature dirt nitrogen or dry air from space division system enter pure argon column through air inlet pipe, change
Scars (such as: solid argon, ice etc.) in hot device and heat exchanger come into full contact with；To make scars melt, by dirty nitrogen or do
Dry air is taken out of, is vented as exhaust gas.Warmed air is vented after pure argon column, heat exchanger as exhaust gas, and it is whole not influence space division
System system operation.It is heated by gas at normal temperature, system is made to restore normally, debug time to be not only greatly reduced quickly,
Avoid the heavy losses that the entire big heating of space division system parking even ice chest takes off sand.Existing pure argon column uses structured packing,
And heat exchanger uses plate-fin heat exchanger (temperature rise effect is more preferable).
Additional air duct is arranged on existing space division pure argon column in the utility model, is arranged in the air outlet of space division pure argon column
Air velocity transducer introduces purification air by air duct, and is entered on pipeline 4 by argon gas and be connected with air duct, while valve is arranged
Door and control system transmit a signal to control system when air velocity transducer 6 detects the heat exchanger tube blocking of space division pure argon column
System, controls the opening in air duct, is closed at argon gas and enters pipeline, so as to be carried out using the purification air of room temperature to heat exchanger
It rises again, reverting equipment runs well when the detection of constant speed sensor is normal.Substantially increase the safety and convenience of system；
The energy consumption of space division test run is also reduced, the requirement of the national present energy-saving and emission-reduction to high energy-consuming industry is met.Improve equipment thing
Therefore the convenience of processing, and largely reduce by one intake valve of test run energy consumption and air inlet pipe of air separation plant in debugging
Road increases limited investment compared with traditional space division is without heating technique, integral device ar system is but made to go wrong in debugging
When, it can handle rapidly.It avoids leading to heavy losses because of local problem.By taking 10000 type space divisions as an example, system total power is about
6300kw calculates by reducing purge time 24 hours, then saves 151200 degree of electricity of power consumption；And once take off about 500,000 yuan of sand expense.
To as it can be seen that the benefit generated is very considerable.
