Description
Technical field
The utility model relates to a kind of sulfur hexafluoride second-time recycling device, belongs to sulfur hexafluoride gas recovery technology field.
Background technology
On domestic and international market, sulfur hexafluoride retrieving arrangement reclaims while end at present, also remaining in interchanger have a large amount of liquid sulfur hexafluorides can not be pressed into steel cylinder, can only be kept in interchanger temporarily, can damage equipment so for a long time, and long-term no words sulfur hexafluoride can slowly be leaked in air, to environment.
Utility model content
The purpose of this utility model is to provide a kind of sulfur hexafluoride second-time recycling device that can overcome above-mentioned defect, the liquid sulfur hexafluoride in interchanger directly can be pressed into steel cylinder by secondary recovery.Its technical scheme is:
Comprise electric switch equipment, interchanger, unit cooler, compressor, sulfur hexafluoride gas cylinder and be provided with the pipeline of check valve, safety valve and reducing valve, it is characterized in that: set up the first motor switch ball valve, the second motor switch ball valve, the 3rd motor switch ball valve, the 4th motor switch ball valve, motor-driven control valve, electro connecting pressure gauge, PLC and 8 rly.s, wherein motor-driven control valve is flow control valve, electro connecting pressure gauge is the tensimeter of band signal output, and the thin copper pipe that refrigeration agent is housed in interchanger is communicated with unit cooler; Electric switch equipment connects the input terminus of compressor through being provided with successively the pipeline of the first motor switch ball valve, reducing valve, electro connecting pressure gauge and safety valve, the output terminal of compressor connects the input terminus of interchanger through being provided with successively the pipeline of check valve and the second motor switch ball valve, the output terminal of interchanger connects the input terminus of sulfur hexafluoride gas cylinder through being provided with the pipeline of the 4th motor switch ball valve; The input terminus of sulfur hexafluoride gas cylinder also connects the junction of check valve and the second motor switch ball valve through being provided with the pipeline of the 3rd motor switch ball valve, the junction of the second motor switch ball valve and interchanger connects on the pipeline of compressor and electric switch equipment in succession through being provided with the pipeline of motor-driven control valve, and tie point is between electro connecting pressure gauge and safety valve; The signal input part of the output termination PLC of electro connecting pressure gauge, the control end of the first motor switch ball valve, compressor, motor-driven control valve, the second motor switch ball valve, unit cooler, interchanger, the 4th motor switch ball valve and the 3rd motor switch ball valve connects respectively the signal output part of PLC through rly..
Its principle of work is: in the time that electric switch equipment starts recovery operation, output a control signal to rly. by PLC, control compressor, interchanger, unit cooler, the first motor switch ball valve, the second motor switch ball valve and the 4th motor switch ball valve and start or open, in electric switch equipment, sulfur hexafluoride gas enters sulfur hexafluoride gas cylinder through the first motor switch ball valve, reducing valve, compressor, check valve, the second motor switch ball valve, interchanger and the 4th motor switch ball valve successively.In the time that pressure recovery reaches requirement, electro connecting pressure gauge outputs signal to PLC, PLC detects after this pressure signal, output a control signal to rly., the first motor switch ball valve, the second motor switch ball valve and the 4th motor switch ball valve are closed in control, open the 3rd motor switch ball valve also increases the aperture of motor-driven control valve simultaneously gradually, now, retain in and change hot-charging device and ducted liquid sulfur hexafluoride and enter into sulfur hexafluoride gas cylinder through motor-driven control valve, compressor, check valve and the 3rd motor switch ball valve successively.Along with the increase of motorized adjustment valve opening, compressor forefront pressure raises gradually, this pressure constantly detected by electro connecting pressure gauge and output detection signal to PLC, in the time that PLC detection electro connecting pressure gauge output signal reaches specified pressure, keep motorized adjustment valve opening no longer to change, maintain compressor forefront pressure within safety range.In the time that PLC detects that electro connecting pressure gauge output signal reaches recovery specified pressure, output a control signal to rly., control close compressor, interchanger, unit cooler, the 4th motor switch ball valve and motor-driven control valve, complete recovery operation.
The utility model compared with prior art, have the following advantages: the liquid sulfur hexafluoride in interchanger directly can be pressed into sulfur hexafluoride gas cylinder by secondary recovery, reduce the long-term infringement that equipment is caused with pressure of equipment, reduced sulfur hexafluoride quantity discharged, alleviate the pollution to environment.
