Description
Technical field
The utility model is related to gas recovery techniques fields, and gas recovering device is sealed more particularly to a kind of expanding machine.
Background technology
In Deep Cooling Method air separation equipment, in order to reduce air themperature, reach liquefied purpose, be configured with expanding machine conduct
The core equipment of cold is obtained, expanding machine must be passed through clean compressed air as blanket gas gas circuit is isolated when running well
And oil circuit, the blanket gas after this part use are vented after flowing out expanding machine, cause energy dissipation, while generate in production scene
Sharp high frequency noise damages the hearing of site operation personnel, and the operating personnel to work in such circumstances for a long time are easy
Obtain the occupational disease of Hearing.
Utility model content
In order to solve the above technical problems, the technical solution that the utility model uses is：A kind of expanding machine sealing is provided
Gas recovering device, which is characterized in that including molecular sieve adsorber and the recovery channel of connection molecular sieve adsorber and expanding machine；Institute
Recovery channel is stated equipped with exhausting pipeline, and exhausting pipeline is connected with recovery channel；The exhausting pipeline is equipped with blow valve；Institute
It states recovery channel and recovery valve, direct-operated regulator and check valve is equipped between exhausting pipeline and molecular sieve adsorber.
Wherein, the recovery channel is equipped between exhausting pipeline and expanding machine and is passed through valve.
Wherein, the recovery valve, direct-operated regulator and check valve are set gradually along air flow recovery direction.
Wherein, the recovery channel is equipped with pressure gauge.
Wherein, the recovery channel is equipped with shut-off valve, and shut-off valve is located at direct-operated regulator and between check valve.
The beneficial effects of the utility model are：
Originally the compressed air being vented can be recycled by the utility model, save electric energy.Work at the same time environment
High frequency noise is effectively controlled, and reduces the risk that operating personnel obtain the occupational disease of hearing reduction.The utility model is easy to operate
Securely and reliably.
Description of the drawings
Fig. 1 is the structure diagram of expanding machine sealing gas recovering device provided by the utility model.
Specific embodiment
The utility model is further described in detail below through specific implementation examples and in conjunction with the accompanying drawings.
The shown expanding machine sealing gas recovering devices provided by the utility model of Fig. 1, including molecular sieve adsorber 8, put
Vacant duct 10, blow valve 2, recovery valve 3, direct-operated regulator 4, check valve 5, shut-off valve 6, is passed through valve 1 and pressure at recovery channel 9
Power table 7；The recovery channel 9 connects molecular sieve adsorber 8 and expanding machine；The recovery channel 9 is equipped with exhausting pipeline 10, and
Exhausting pipeline 10 is connected with recovery channel 9；The exhausting pipeline 10 is equipped with blow valve 2；The recovery channel 9 is in exhausting pipeline
Recovery valve 3, direct-operated regulator 4 and check valve 5 are equipped between 10 and molecular sieve adsorber 8.
Recovery channel 9 is equipped between exhausting pipeline 10 and expanding machine and is passed through valve 1；The recovery valve 3, direct-operated regulator
4 and check valve 5 set gradually along the air flow recovery direction of recovery channel 9；The recovery channel 9 is equipped with pressure gauge 7；Described time
Closed tube road 9 is equipped with shut-off valve 6, and shut-off valve 6 is located at direct-operated regulator 4 and between check valve 5.
Expanding machine runs early gate state：Blanket gas is passed through valve 1, blow valve 2, shut-off valve 6 and is in opening, recovery valve
3rd, direct-operated regulator 4, check valve 5 are in closed state, and pressure gauge is in use state.
Expanding machine startup stage, due to expanding machine fluctuation of service, blow valve 2 is opened at this time, and blanket gas passes through blow-down pipe
Road 10 is vented.
Expanding machine start-up course terminates after entering stable operation, carries out expanding machine blanket gas reclaimer operation at this time, slowly beats
Recovery valve 3 is opened, simultaneously closes off blow valve 2；After 9 pressure rise of recovery channel, direct-operated regulator 4 is according to the pressure detected
It automatically turns on, when pressure is higher than 8 pressure of molecular sieve adsorber after check valve 5 in recovery channel 9, check valve 5 automatically opens out
Begin to recycle.
In expanding machine normal course of operation, sealing atmospheric pressure and flow are automatically controlled by direct-operated regulator 4.
If expanding machine is because accidental cause is out of service suddenly, when 8 pressure of molecular sieve adsorber is higher than sealing atmospheric pressure,
Check valve 5 is automatically closed, and prevents the air of 8 moisture content of molecular sieve adsorber from entering expanding machine and causes equipment fault.
Before expanding machine is shut down, recovery valve 3 is progressively closed off, while open blow valve 2.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is directly or indirectly used in
Other related technical areas are equally included in the patent within the scope of the utility model.
