Abstract
The utility model relates to a vacuum machine set for a rectification tower with a tail gas recovery device. The existing vacuum machine set can not recover tail gas from the rectification tower, the environment is severely polluted and the service life of a pump is short. The utility model comprises a plurality of Roots pumps and a vacuum pump which is connected with the Roots pumps in a series connection mode. The utility model is characterized in that saline water condensers are connected to the position between the adjacent Roots pumps in a series connection mode; a liquid outlet condensed by each saline water condenser is connected with a residual liquid recovery jar by pipes. The utility model carries out recovery and treatment of the tail gas by a plurality of salt water condensers, the environmental pollution is reduced and the service life of the pump is increased.
Description
Technical field
The utility model relates to the vacuum unit in the rectifying column.
Background technology
Owing to contain 1%～2% low-boiling-point substance in the existing rectifying column still tail gas discharged, it can't be cooled off by overhead condenser, enter into the vacuum unit of rectifying column, pulled away by a plurality of lobe pumps in the unit and no oily vertical type vacuum pump, a large amount of organic matters is discharged in air and the ditch, serious environment pollution; When simultaneously this part low-boiling-point substance is through each lobe pump and no oily vertical type vacuum pump, the liquid that part low-boiling-point substance cooling obtains is attracted to the rotor surface of each lobe pump and carbonization, because two rotor clearances of lobe pump are originally with regard to little (having only 0.2mm), carbide makes the gap littler, along with the pump operation time lengthening, the carbide thickening of rotor surface increases motor load, temperature improves, frictional resistance increases, and is as easy as rolling off a log stuck, the bigger service life that shortens pump.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and provides a kind of and can reclaim organic rectifying column vacuum unit in the tail gas, to reduce environmental pollution, prolongs the service life of pump.
For this reason, the utility model adopts following technical scheme: the rectifying column vacuum unit of magnetic tape trailer gas recovering device, the vavuum pump that comprises a plurality of lobe pumps and series connection with it, it is characterized in that being in series with brine condenser between adjacent lobe pump, the liquid outlet that described each brine condenser condensation is got off reclaims altar by pipe and raffinate and is connected.The utility model can not only reduce the discharging of organic toxicant by finish up back and forth organic matter in the gas of brine condenser, has reduced environmental pollution, and can make prolong several times the service life of each lobe pump and vavuum pump.
The rectifying column vacuum unit of described magnetic tape trailer gas recovering device is positioned at lobe pump upper end foremost and is connected with described raffinate recovery altar by the vacuum balance pipe immediately following thereafter lobe pump lower end.Reclaim altar for the raffinate that recovery is obtained enters raffinate smoothly, make the vacuum of raffinate recovery altar be close to or higher than the vacuum of brine condenser by the vacuum balance pipe.
The rectifying column vacuum unit of described magnetic tape trailer gas recovering device also is in series with brine condenser before being positioned at lobe pump foremost; Also be in series with brine condenser between lobe pump and vavuum pump.After a plurality of brine condensers recovery, enter the content of organics in the ditch at last, reached discharging standards (COD is less than 100mg/L) after testing.
The utility model recycles tail gas by a plurality of brine condensers, has following beneficial effect: reduced the discharging of organic toxicant, reduced environmental pollution; Prolonged the service life of each lobe pump and vavuum pump, reduced the lobe pump temperature rise, the machine maintenance expense is few, and motor load is little, and electric energy is economized; Enter the content of organics in the ditch at last, reached discharging standards after testing, saved the required big expense of waste water of handling.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Rectifying column vacuum unit as shown in Figure 1 comprises a no oily vertical type vacuum pump 2 of three lobe pump 1-1,1-2,1-3 series connection with it, is connected in series hypothermic saline condenser 3-1 between overhead condenser 11 and lobe pump 1-1; Between lobe pump 1-1 and lobe pump 1-2, be connected in series brine condenser 3-2, between lobe pump 1-2 and lobe pump 1-3, be connected in series brine condenser 3-3; Be connected in series brine condenser 3-4 at lobe pump 1-3 with 2 of no oily vertical type vacuum pumps.Tail gas is through 4 brine condenser 3-1,3-2,3-3,3-4 cooling, with the raffinate that cools down, introduce raffinate through pipe 8,12 and reclaim altar 9, introduce raffinate through pipe 6 and reclaim altar 4, reclaim in the altar 9 and 4 in order to make the recovery raffinate enter raffinate smoothly, by reclaiming altar 9 indirect vacuum balance pipes 7 with raffinate in lobe pump 1-1 upper end, reclaim altar 4, indirect vacuum balance pipe 5 by lobe pump 1-2 lower end and raffinate, the vacuum that makes raffinate reclaim altar 9 and 4 is higher than the vacuum of each brine condenser.Raffinate reclaims altar 9 and links to each other by pipe 10 with 4, makes in the raffinate recovery altar 9 raffinate put into raffinate recovery altar 4, puts bucket then.
Contain 1%～2% low-boiling-point substance in the rectifying column tail gas discharged, the recovery through four brine condensers in this device enters the content of organics in the ditch at last, reaches discharging standards after testing, and COD is less than 100mg/L.
Claims (4)
1, the rectifying column vacuum unit of magnetic tape trailer gas recovering device, the vavuum pump that comprises a plurality of lobe pumps and series connection with it, it is characterized in that being in series with brine condenser between adjacent lobe pump, the liquid outlet that each brine condenser condensation is got off reclaims altar by pipe and raffinate and is connected.
2, the rectifying column vacuum unit of magnetic tape trailer gas recovering device according to claim 1 is characterized in that being positioned at lobe pump upper end foremost and is connected with described raffinate recovery altar by the vacuum balance pipe immediately following thereafter lobe pump lower end.
