Description
Technical field
The utility model relates to a kind of vaccum-pumping equipment, especially a kind of vacuum pump set vacuumized for fatty acid rectifying column.
Background technique
Croude fatty acids can isolate the raw materials of industry such as pitch, stearic acid and oleic acid through rectifying, need to vacuumize process to rectifying column in distillation process, the degree of vacuum in rectifying column is made to reach more than-97kpa, because degree of vacuum is higher, usual employing is connected into vacuum pump set by Roots pump and Nash hytor and vacuumizes rectifying column.During work, the gas in rectifying column is successively through Roots pump at different levels, and the relief opening finally by Nash hytor is directly discharged into air.A small amount of low carbon chain fatty acid and water can be carried due in the gas extracted out in rectifying column, after low carbon chain fatty acid and water enter the cold and hot exchange of Nash hytor, low carbon chain fatty acid will be attached on water ring vacuum pump vane, not only corrode the life-span that impeller affects water ring vaccum pump, also can increase the load of water ring vaccum pump, the degree of vacuum of final influential system, causes affecting quality of product.
Model utility content
The technical problem that model utility will solve is: provide a kind of fatty acid rectifying column to vacuumize Special vacuum unit, the low carbon chain fatty acid that carries and water the gas extracted out from fatty acid rectifying column can be avoided during the work of this Special vacuum unit to enter Nash hytor, cause Nash hytor impeller to corrode, increase the load of water ring vaccum pump.
The technological scheme that technical solution problem is taked: a kind of fatty acid rectifying column vacuumizes Special vacuum unit, comprise the first order Roots pump be connected in series in turn, second level Roots pump and third level Roots pump, the suction port of first order Roots pump connects fatty acid rectifying column vacuum-pumping tube, the lower outlet pipe of an exhaust is downwards connected at the relief opening of third level Roots pump housing bottom, lower outlet pipe connects closed collecting tank, drainage conduit and discharge valve is connected to bottom closed collecting tank, lateral row tracheae is connected at the tube wall of lower outlet pipe, the suction port of lateral row tracheae water receiving ring vacuum pumps, Nash hytor relief opening runs in blank pipe.
As improvement of the present utility model: lateral row tracheae becomes angle to be obliquely installed with horizontal plane, the gas of discharging from third level Roots pump advances to upward slope direction at lateral row tracheal strips, arrives Nash hytor suction port.
As further improvement of the utility model: the speed of exhaust of described first order Roots pump is 1200L/s, the speed of exhaust of second level Roots pump is 600L/s, and the speed of exhaust of third level Roots pump is 300L/s.
Beneficial effect: fatty acid rectifying column of the present utility model vacuumizes Special vacuum unit, vacuumize Special vacuum unit and comprise owing to have employed described fatty acid rectifying column the first order Roots pump be connected in series in turn, second level Roots pump and third level Roots pump, the suction port of first order Roots pump connects fatty acid rectifying column vacuum-pumping tube, the lower outlet pipe of an exhaust is downwards connected at the relief opening of third level Roots pump housing bottom, lower outlet pipe connects closed collecting tank, drainage conduit and discharge valve is connected to bottom closed collecting tank, lateral row tracheae is connected at the tube wall of lower outlet pipe, the suction port of lateral row tracheae water receiving ring vacuum pumps, Nash hytor relief opening runs in the technological scheme of blank pipe, lateral row tracheae is connect by other on the tube wall of lower outlet pipe, in the enclosed collecting tank low carbon chain fatty acid that carries in the gas extracted out from fatty acid rectifying column and water being entered under gravity be connected below lower outlet pipe, to collect in enclosed collecting tank and to concentrate emission treatment by drainage conduit and discharge valve, remaining gas enters Nash hytor by lateral row tracheae, directly be discharged in air through Nash hytor, therefore, the low carbon chain fatty acid that carries in the gas extracted out from fatty acid rectifying column and water can be avoided to enter Nash hytor corrosive water circular vacuum pump impeller when fatty acid rectifying column of the present utility model vacuumizes the work of Special vacuum unit, extend the working life of Nash hytor, reduce the maintenance cost of equipment, it also avoid low carbon chain fatty acid simultaneously and be attached to load impeller increasing water ring vaccum pump, and the degree of vacuum of influential system, finally affect quality of product, angle is become to be obliquely installed owing to have employed lateral row tracheae with horizontal plane, the technical characteristics that gas is advanced to upward slope direction at lateral row tracheal strips, a small amount of low carbon chain fatty acid residual in the gas in outlet pipe and water is made to be deposited on tube wall in the process of advancing, and conflux downwards along tube wall and enter collecting tank, further avoid low carbon chain fatty acid and water to enter Nash hytor and impact Nash hytor, fatty acid rectifying column of the present utility model is made to vacuumize the work of Special vacuum unit more stable, reliable, the longer service life of Nash hytor, owing to reasonably defining the speed of exhaust of Roots pump at different levels, each the vacuum pump making fatty acid rectifying column of the present utility model vacuumize Special vacuum unit all can be in suitable operating mode, vacuumizing effect is better, make to remain stable degree of vacuum in fatty acid rectifying column, the isolated quality of product of institute is better.
