Description
Technical field
The utility model is related to the packing seals of mechanical equipment, and in particular to a kind of to prevent by the solid in compressed gas
Grain blocks the device of packing ring.
Background technology
Fujian Fu Yuan Kai Meite gases Co., Ltd is purified using pressure swing adsorption technique from the torch gas that oil plant discharges
Go out hydrogen and fuel gas.Pressure swing adsorption technique has the step of carrying out desulfurization to the torch gas discharged from oil plant.It is walked in desulfurization
In rapid, pressurized treatments are carried out to the torch gas discharged from oil plant using more LGW710/0685 types screw compressors.Such as figure
Shown in 2, LGW710/0685 types screw compressor 100 has a torch gas import 110 and torch gas outlet 120.Neighbouring
The torch gas outlet 120 i.e. high-pressure side of LGW710/0685 type screw compressors, which has, is arranged on screw shaft outer wall and screw shaft
Stuffing seal 130 between through-hole wall.Stuffing seal 130 has multiple carbon sealing rings.In order to improve sealing effect
Fruit is opened between screw shaft through-hole wall and body outer wall there are three through-hole 131,132 and 133, three through-holes 131,132 and
133 are located at the surface of screw shaft.On screw shaft through-hole wall, it is provided with what is communicated respectively with three through-holes 131,132 and 133
Three annular grooves.Through-hole 131 for being filled with nitrogen into stuffing seal 130, press by a little higher than torch gas outlet of pressure
Power, high-pressure side torch gas to be prevented to be revealed to 133 side of through-hole, into high-pressure side bearing housing.Through-hole 132 is used to discharge to through-hole
The nitrogen and a small amount of torch gas of 132 sides leakage.Through-hole 133 is used to discharge the nitrogen revealed to 133 side of through-hole and micro torch gas.
But containing dust particles and softened water in torch gas, relying only on through-hole 133 cannot be in time in sealing device
Dust particles are discharged, and dust particles are slowly accumulated, and block carbon sealing ring, and seal failure causes torch gas to high-pressure side bearing housing
A large amount of leakages, softened water are channeled in the lubricating oil of high-pressure side bearing housing, and compressor is not normally functioning, and cause very big economic damage
It loses.
Utility model content

Technical problem provides a kind of device for preventing from being blocked packing ring by the solid particle in compressed gas.
The device for preventing from being blocked packing ring by the solid particle in compressed gas of the utility model, which is characterized in that tool
There are a liquid collecting tank and an infusion pump；
Through-hole there are one being opened between shaft through-hole inner wall and body outer wall at compressor installation stuffing seal, is located at
The underface of axis；
One end of one first pipeline is connected with through-hole, and the other end is connect with the import of the inlet tube on liquid collecting tank top；
One end of one second pipeline is connect with the outlet of the outlet of liquid collecting tank lower part, and the import of the other end and infusion pump connects
It is logical；
The inlet communication of one end of one third pipeline and the outlet of infusion pump, the other end and compressor；
The outlet connection of outlet at the top of one end of one the 4th pipeline and liquid collecting tank, the import of the other end and compressor connect
It is logical.
The device for preventing from being blocked packing ring by the solid particle in compressed gas of the utility model, thoroughly solves entrance
The technical issues of dust particles in the sealing device of existing compressor cannot discharge in time.
Description of the drawings
Fig. 1 is that the main view of the device for preventing from blocking packing ring by the solid particle in compressed gas of the utility model is illustrated
Figure, has made longitudinal section view to the driving screw rod mechanism of screw compressor therein；
Fig. 2 is the elevational schematic of the driving screw rod mechanism of existing screw compressor.
Specific embodiment
With reference to the accompanying drawings and detailed description the utility model is prevented from being blocked up by the solid particle in compressed gas
The device of plug packing ring is further described.
Referring to Fig. 1, the device by the solid particle blocking packing ring in compressed gas that prevents of the utility model has one
200 and one infusion pump 300 of liquid collecting tank.
It is opened between the screw shaft through-hole wall of screw compressor 100 and body outer wall there are one through-hole 140, positioned at spiral shell
The underface of bar axis is communicated with the annular groove communicated with through-hole 133.
One end of one first pipeline 210 is connected with through-hole 140, the inlet tube 230 on the other end and 200 top of liquid collecting tank into
Mouth connection.
One end of one second pipeline 220 is connect with the outlet of the outlet 240 of 200 lower part of liquid collecting tank, the other end and infusion
The import 310 of pump 300 connects.
One end of one third pipeline 330 is connected with the outlet 320 of infusion pump 300, the other end and screw compressor 100
Torch gas import 110 connects.
One end of one the 4th pipeline 270 is connect with the outlet of the outlet 260 at 200 top of liquid collecting tank, the other end and screw rod
The torch gas import 110 of formula compressor 100 connects.
There is a blow-off pipe 250 in 200 bottom of liquid collecting tank.
Liquid collecting tank 200 has a liquid level meter 280.
Valve is installed on the first pipeline 210, the second pipeline 220,330 and the 4th pipeline 270 of third pipeline.
Valve is installed on blow-off pipe 250.
The device for preventing from being blocked packing ring by the solid particle in compressed gas of the utility model is specifically used as follows：
The valve on the first pipeline 210, the second pipeline 220,330 and the 4th pipeline 270 of third pipeline is opened, from
Gas, dust particles and the downward via through holes 140 of softened water and pipeline 210 in the torch gas that stuffing seal 130 is revealed are logical
It crosses inlet tube 230 to enter in liquid collecting tank 200, the gas in torch gas returns to spiral shell through 260 and the 4th pipeline 270 of outlet upwards
The torch gas import 110 of rod-type compressor 100, dust particles and softened water in torch gas drop downward into 200 bottom of liquid collecting tank,
Tank bottom is sunk to after dust is static, is periodically discharged by blow-off pipe 250, softened water enters defeated through 240 and second pipeline 220 of outlet
The import 310 of liquid pump 300, outlet 320 and third pipeline 330 through infusion pump 300 return to the torch of screw compressor 100
Gas import 110.
Using the device for preventing from being blocked packing ring by the solid particle in compressed gas of the utility model, from packing seal
Gas, dust particles and softened water in the torch gas that device 130 is revealed can be discharged from stuffing seal 130 in time, fire
Dust particles in torch gas no longer block carbon sealing ring, and the gas and softened water in torch gas return to screw compressor 100
Torch gas import 110, reused.It prevents from being filled out by the solid particle blocking in compressed gas using the utility model
Before the device for expecting ring, helical-lobe compressor, which is run one month or so, must just replace carbon sealing ring；Using preventing for the utility model
After the device that packing ring is blocked by the solid particle in compressed gas, helical-lobe compressor is run six months, not yet finds that carbon is close
Seal ring blocks.
