For guaranteeing device security, three tank bodies can also arrange respectively pressure release valve.
Adopt the using method of sulfur hexafluoride gas purification purification group tank of the present utility model, comprise the steps:
Step 1, with sulfur hexafluoride gas after sorbent material absorption, obtain pending sulfur hexafluoride gas; The sorbent material that uses is the domestic molecular sieve that adsorbs for the moisture in the sulfur hexafluoride, degradation production and toxic substance specially, can adsorb the materials such as S2F2, SF2, SF4, SOF2, SO2, SOF4, SO2F2, S2F10, S2F10O, HF, WF6, SIF4, CF4.Adsorption treatment work to sulfur hexafluoride gas extensively is used in the inner and a large amount of recycling and processing devices of switching gas chamber of each large high voltage switch gear factory, and this molecular sieve can carry out high-temperature activation processing recycling.
Step 2, close the second valve 26 and the 6th valve 20, pending sulfur hexafluoride gas is introduced the first liquefied pot 7 by inlet mouth 22, the first refrigerating coils 28 in the first liquefied pot 7 pass into refrigeration agent and reduce that temperature to sulfur hexafluoride gas liquefies in the tank, because action of gravity, liquid sulfur hexafluoride enters the second liquefied pot 10 that the first liquefied pot 7 bottoms are set through the 3rd valve 18, the second refrigerating coil 29 in the second liquefied pot 10 passes into the refrigeration agent cooling, the liquid state that keeps sulfur hexafluoride, and the gas in the second liquefied pot 10 is extruded by liquid sulfur hexafluoride, enters in the first liquefied pot 7 through the 4th valve 8;
Step 3, detect liquid level in the first liquefied pot 7 by the second liquid level sensor 25, because the second liquefied pot 10 is positioned at the bottom of the first liquefied pot 7, if in the first liquefied pot 7 liquid level is arranged, represent that namely the second liquefied pot 10 has been full of liquid sulfur hexafluoride; Close the 3rd valve 18 and the 4th valve 8 this moment, opens the 5th valve 12 liquid sulfur hexafluoride is reclaimed by the first liquid outlet 11, stops to close the 5th valve 12 to the second refrigerating coil 29 logical refrigeration agents after recovery is finished;
Step 4, open the second valve 26, close the first valve 2, make pending sulfur hexafluoride gas in the 7 interior liquefaction of the first liquefied pot, because action of gravity, the first liquefied pot 7 interior gases enter exhaust tank 4 through valve 26, observe the second liquid level sensor 25, extremely liquid sulfur hexafluoride is full of in the first liquefied pot 7;
Step 6, this moment can be carried out the selection that equipment uses according to the amount of pending sulfur hexafluoride gas, if pending amount is large, inlet mouth 22 is still waiting to process sulfur hexafluoride gas and passes into, and then repeating step 2 is introduced the second liquefied pot 10 and recovery to step 4 with liquid sulfur hexafluoride; If pending amount is little, inlet mouth 22 passes into without pending sulfur hexafluoride gas, enters step 7, only uses the first liquefied pot 7 to carry out the recovery of liquid sulfur hexafluoride;
Step 7, close the second valve 26, open the 6th valve 20, the liquid sulfur hexafluoride that reclaims in the first liquefied pot 7 through the second liquid outlet 19;
Step 8, open the first valve 2, residual gas in the exhaust tank 4 is drawn in the neutralization tank reclaims, the obnoxious flavour of remnants is dissolved and adsorb, finally can not damage environment.
