Description
Technical field
The utility model relates to a kind of sulfur hexafluoride recovery and uses deep cooling type gas separation system, belongs to sulfur hexafluoride gas recovery technology field.
Background technology
On domestic and international market, sulfur hexafluoride reclaiming and recharging device is all to lower the temperature to reclaiming tank body at present, make sulfur hexafluoride compressed liquid that becomes in tank body carry out again canned, cooling-down effect is undesirable, and it is bulky to install tank body additional, heat exchange efficiency is low, after reclaiming, remaining sulfur hexafluoride is more in tank body, and air plankton is not easy to separate and discharges, and accumulates in that in tank body, to cause reclaiming purity not high.
Utility model content
The purpose of this utility model be to provide a kind of can overcome above-mentioned defect, cooling rate fast, reclaim sulfur hexafluoride that purity is high and reclaim and use deep cooling type gas separation system.Its technical scheme is:
A kind of sulfur hexafluoride reclaims uses deep cooling type gas separation system, it is characterized in that: comprise sulfur hexafluoride compressor, motor-driven valve, fan heat exchanger, refrigeration unit, full-liquid type shell-and-tube heat exchanger, lower tank, needle valve, upper tank body, Pressure gauge, hand-operated valve and steel cylinder, wherein the outlet of sulfur hexafluoride compressor is communicated with steel cylinder through motor-driven valve, fan heat exchanger, full-liquid type shell-and-tube heat exchanger, lower tank and hand-operated valve successively, lower tank is communicated with upper tank body through needle valve, and air bleeding valve is equipped with on the top of upper tank body.
Described sulfur hexafluoride reclaims uses deep cooling type gas separation system, and fan heat exchanger adopts fin type fan heat exchanger, and hand-operated valve adopts manual ball valve, and motor-driven valve adopts motor switch ball valve, and Pressure gauge adopts mechanical shockproof Pressure gauge.
Described sulfur hexafluoride reclaims to be used deep cooling type gas separation system, full-liquid type shell-and-tube heat exchanger to comprise a vapor tight tank and is coiled in the thin copper pipe in hermetically sealed can, and the thin in-built cold-producing medium of copper pipe, is communicated with refrigeration unit.
Its operation principle is: first by fan heat exchanger, the high pressure-temperature gas after to sulfur hexafluoride compressor compresses is tentatively lowered the temperature, sulfur hexafluoride gas after preliminary cooling enters in the hermetically sealed can of full-liquid type shell-and-tube heat exchanger, carry out heat exchange with the thin copper pipe that is communicated with refrigeration unit, make sulfur hexafluoride carry out fast cooling, boil down to liquid state, when liquid sulfur hexafluoride process lower tank, the air plankton that is difficult for being liquefied will automatically separate through needle valve and enter upper tank body, and all the other liquid sulfur hexafluorides flow into steel cylinder through hand-operated valve control and collect.
The utility model compared with prior art, has advantages of following aspect:
1, sulfur hexafluoride gas is adopted to wind cooling temperature lowering and two kinds of modes of refrigeration unit cooling, wherein full-liquid type shell-and-tube heat exchanger is the mode that cold-producing medium directly contacts with sulfur hexafluoride, and heat exchange efficiency is high, and cooling rate is fast.
2, adopt upper tank body and lower tank to coordinate with needle valve, effectively filtering air plankton, has improved recovery purity, and has effectively avoided the pressure rising problem too much causing because of air.
3, save fluid reservoir, reduced system bulk, reduced cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1, sulfur hexafluoride compressor 2, motor-driven valve 3, fan heat exchanger 4, refrigeration unit 5, lower tank 6, needle valve 7, upper tank body 8, Pressure gauge 9, hand-operated valve 10, steel cylinder 11, air bleeding valve 12, vapor tight tank 13, thin copper pipe 14, pressure transmitter
The specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.In the embodiment shown in fig. 1: the outlet of sulfur hexafluoride compressor 1 is communicated with steel cylinder 10 through motor-driven valve 2, fan heat exchanger 3, full-liquid type shell-and-tube heat exchanger, lower tank 5 and hand-operated valve 9 successively, lower tank 5 is communicated with upper tank body 7 through needle valve 6, and air bleeding valve 11 is equipped with on the top of upper tank body 7.Wherein full-liquid type shell-and-tube heat exchanger comprises a vapor tight tank 12 and is coiled in the thin copper pipe 13 in hermetically sealed can, and the thin in-built cold-producing medium of copper pipe 13, is communicated with refrigeration unit 4; Fan heat exchanger 3 adopts fin type fan heat exchanger 3, and hand-operated valve 9 adopts manual ball valve, and motor-driven valve 2 adopts motor switch ball valve, and Pressure gauge 8 adopts mechanical shockproof Pressure gauge.
When work, before sulfur hexafluoride compressor 1 is opened, open motor-driven valve 2, hand-operated valve 9, needle valve 6 and fan radiator 3, refrigeration unit 4 is synchronously opened, sulfur hexafluoride gas enters fan radiator 3 through motor-driven valve 2 and is cooled to normal temperature, then enter full-liquid type shell-and-tube heat exchanger, temperature continues to drop to-10 ℃, now sulfur hexafluoride is under high pressure converted into liquid state, liquid sulfur hexafluoride, through lower tank 5, filters the air plankton that is difficult for being liquefied to be expelled to upper tank body 7, and all the other gases that are liquefied are controlled and entered steel cylinder 10 through hand-operated valve 9.Recovery finishes the rear air bleeding valve 11 that gently opens, and air plankton is discharged.
