Summary of the invention
The purpose of this utility model is in that to overcome above-mentioned deficiency, it is provided that the dry vacuum unit of a kind of efficient, energy-conservation and environmental protection。
The purpose of this utility model is achieved in that
A kind of dry vacuum unit, described dry vacuum unit includes one-level Roots vaccum pump, two grades of Roots vaccum pumps and screw vacuum pump, the air inlet of dry vacuum unit is by the air inlet of pipeline connection to one-level Roots vaccum pump, the gas outlet of described one-level Roots vaccum pump is by the air inlet of pipeline connection to two grades of Roots vaccum pumps, the gas outlet of described two grades of Roots vaccum pumps is communicated to the air inlet of screw vacuum pump by the road, the external aerofluxus in gas outlet of described screw vacuum pump。
This utility model one dry vacuum unit, the air inlet of described one-level Roots vaccum pump is in series with automatic switch valve and pressure transmitter。
This utility model one dry vacuum unit, described two grades of pipelines between Roots vaccum pump and screw vacuum pump are in series with cooler, temperature transmitter and automatic check valve。
This utility model one dry vacuum unit, the gas outlet of described screw vacuum pump is in series with tail gas recycle capturing device and acoustic filter。
This utility model one dry vacuum unit, above-mentioned one-level Roots vaccum pump and two grades of Roots vaccum pumps are gas circulating cooling type Roots vaccum pump。
This utility model one dry vacuum unit, the movable sealing of above-mentioned one-level Roots vaccum pump and two grades of Roots vaccum pumps is mechanical seal structure。
This utility model one dry vacuum unit, described tail gas recycle capturing device is to be made up of housing, condensing tube, whirlwind deflector, drainage screen。
Compared with prior art, the beneficial effects of the utility model are:
After adopting this utility model energy-saving environment protection vacuum unit, maximum energy consumption is only about the 1/4 of original multistage steam ejector pump unit, and can realize the zero-emission of waste gas, waste water。It is crucial that the investment of new equipment, the energy-conservation expense of a year just can reclaim all investments of reforming equipment, and therefore, from economic benefit angle, worth enterprise uses, and is more worthy to be popularized from the viewpoint of social benefit environmental protection；And this utility model dry vacuum unit, pumping performance is stable, reliable, and energy consumption is low, noise is little, without waste gas, without discharging of waste liquid, it is possible to be truly realized energy-conserving and environment-protective。
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of dry vacuum unit of this utility model。
Wherein:
Automatic switch valve 1, pressure transmitter 2, one-level Roots vaccum pump 3, two grades of Roots vaccum pumps 4, cooler 5, temperature transmitter 6, automatic check valve 7, screw vacuum pump 8, tail gas recycle capturing device 9, acoustic filters 10。
Detailed description of the invention
Referring to Fig. 1, a kind of dry vacuum unit that this utility model relates to, described dry vacuum unit includes 3, two grades of Roots vaccum pumps 4 of one-level Roots vaccum pump and screw vacuum pump 8, air inlet is by the air inlet of pipeline connection to one-level Roots vaccum pump 3, the gas outlet of described one-level Roots vaccum pump 3 is by the air inlet of pipeline connection to two grades of Roots vaccum pumps 4, the gas outlet of described two grades of Roots vaccum pumps 4 is communicated to the air inlet of screw vacuum pump 8 by the road, the external aerofluxus in gas outlet of described screw vacuum pump 8；
Operation principle of the present utility model is:
Being connected by the air inlet of the gas outlet with this dry vacuum unit that are evacuated equipment, when being evacuated the heating material in equipment, the equipment of being evacuated is started evacuation by this dry vacuum unit；Reach uniform temperature and certain vacuum degree when the material being evacuated in equipment after, the material being evacuated in equipment reaches gas-liquid saturation, and it is steam that liquid material starts a large amount of vaporization。Difference according to material to be processed composition, the retracting device that can coagulate steam can be installed on the connecting line being evacuated between system and dry vacuum unit, partial material steam can be condensed into liquid before entering dry vacuum unit and reclaim by retracting device, the gas not being condensed sucks one-level Roots vaccum pump 3, sucked by two grades of Roots vaccum pumps 4 after one-level Roots vaccum pump 3 compresses, compression then through two grades of Roots vaccum pumps 4 enters screw vacuum pump 8, owing to complete equipment can accomplish full-closed structure, this ensures that there the waste gas of unit, the zero-emission of waste water。
Above-mentioned for most simplified system of the present utility model；Further elaborate below in conjunction with Fig. 1；
Further, the air inlet of described one-level Roots vaccum pump 3 is in series with automatic switch valve 1 and pressure transmitter 2；
Further, the pipeline between described two grades of Roots vaccum pumps 4 and screw vacuum pump 8 is in series with cooler 5, temperature transmitter 6 and automatic check valve 7；
Further, the gas outlet of described screw vacuum pump 8 is in series with tail gas recycle capturing device 9 and acoustic filter 10；Gas is entered tail gas recycle capturing device 9 by screw vacuum pump 8 again, is again condensed and reclaims in tail gas recycle catcher 9, and remaining air is discharged in air after acoustic filter noise reduction again。
Preferably, above-mentioned one-level Roots vaccum pump 3 and two grades of Roots vaccum pumps 4 are gas circulating cooling type Roots vaccum pump；And the movable sealing of one-level Roots vaccum pump 3 and two grades of Roots vaccum pumps 4 is mechanical seal structure；
Preferably, tail gas recycle capturing device 9 is to be made up of housing, condensing tube, whirlwind deflector, drainage screen etc., and it is overanxious that the particulate matter in pumped gas can carry out secondary, condensable gas is condensed into liquid and reclaims, and so can stop the direct discharge of toxic and harmful。
Additionally: it should be noted that above-mentioned detailed description of the invention is only a prioritization scheme of this patent, any change that those skilled in the art does according to above-mentioned design or improvement, all within the protection domain of this patent。
