Description
Technical field
Model utility is the improvement to the high-temperature systems vacuum pumping device, particularly a kind of smelting vacuum pumping device.
Background technique
In vacuum smelting, often adopt the steam jet vaccum of tandem compound, thick-smart two-step filter, intercondenser three parts composition vacuum pumping device, above-mentioned vacuum pumping device exists deficiency to have:
Steam ejection vacuum pump (Fig. 2), steam inlet tube 5 laterally enters, and is that flange is connected with the Laval nozzle of axial setting, leaks in the joint easily produces like this, and serious meeting influences the vacuum pump performance; In addition, steam directly enters, when steam enters pressure surge big, can cause the degree of vacuum instability.Secondly, gas mixer chamber 6 is a cylindrical structure, and resistance is big when causing pumped gas to suck; Besides, the pump housing diffuser pipe angle of throat of existing jet pump is bigger, usually at 10-15 °, easily produces the degree of vacuum bounce-back in course of injection, and influence vacuumizes efficient.
Slightly-and smart two-step filter (Fig. 4), adopt cooling and dedusting device 9 and dust removal filter 12 tandem compounds.Pumped gas cooling of cooling tube 10 heat exchanges in cooling and dedusting device 9 earlier and collision dedusting are again by Stainless Steel Cloth 11 dust removals by filtration in the dust removal filter 12.This is thick-and smart two-step filter is a two-stage tandem, and particularly level dust removal by filtration in back causes fluid resistance big, has not only prolonged the forvacuum time, and has increased energy consumption relatively, and the resistance of bleeding is big, also can cause ultimate vacuum low.
Intercondenser, cooling water are by collecting chamber upper nozzle spray, and with the steam heat exchange, the gas-liquid area of contact is little, and cooling effect is poor; And nozzle stops up easily.
Therefore still having is worth improved place.
The model utility content
The model utility purpose is to overcome the deficiency of above-mentioned prior art, provides a kind of forvacuum time short, ultimate vacuum height, vacustat, the smelting vacuum pumping device that energy consumption is low.
The model utility purpose realizes, mainly is that steam jet vaccum, thick-smart two-step filter and intercondenser are improved, thereby overcomes the deficiencies in the prior art, realizes the model utility purpose.Specifically, model utility is smelted and is used vacuum pumping device, comprise the steam jet vaccum of tandem compound successively, the cooling and dedusting device, intercondenser is characterized in that said steam jet vaccum, and the steam tube of connection nozzle and nozzle are in the same way, its entrance point has the steam plenum, and gas mixer chamber is bend pipe structure; Said cooling and dedusting device is the vortex type cooling and dedusting device that top water composite cooling pipe, below cyclone blade are formed; Said intercondenser is made up of top spray equipment, below airflow dispersion device.
Model utility is said
Steam jet vaccum pump housing diffuser pipe, identical with prior art steam jet vaccum structure, there are tapered conical pipeline section, aditus laryngis, flaring taper pipeline section to constitute.
Gas mixer chamber, same as the prior art, effect is that the gas of pressure difference is mixed, and produces pumping action, and its bend angle is preferably the 45-90 degree, and test shows that this angle has the littler resistance of bleeding.
For effectively reducing degree of vacuum bounce-back, a kind ofly more preferably pump housing diffusion pipeline section two ends angle of throat is reduced, by original 10-15 °, be reduced to 5-10 °, little angle of throat has effectively reduced the degree of vacuum bounce-back, thereby makes the degree of vacuum of pumped gas more stable.
Vortex type cooling and dedusting device, by top water composite cooling pipe, the combined integrated structure of below cyclone blade, and adopt cyclone blade to produce the centrifugation dedusting, not only particle separation diameter is littler, can separate dust more than 50 microns, separating effect improves, therefore can be former slightly-smart two-stage dedusting becomes primary dust removing.Thereby reduced draw resistance greatly, shortened the forvacuum time, improved ultimate vacuum, reduced energy consumption.
Intercondenser top spray equipment mainly plays the water spray effect, to increase the gas-liquid area of contact, improves cooling effect.Can be one or multistage aproll arc plate, can also be one or multi-stage spray spraying device such as shower nozzle; The below airflow dispersion device, be for increasing heat exchange air-flow area of contact equally, can adopt one or multistage awl and/or arc spoiler, allow gas-liquid fully contact, to mix, also can adopt one or multistage eddy flow crack plate, to increase the gas-liquid area of contact, other gases that can also adopt the technician to know loose and flow device.
Model utility is smelted and used vacuum pumping device, owing to adopt said structure, has than prior art: leak in being difficult for producing, the nozzle admission is stable, be not subject to enter the vapor pressure influence of fluctuations, and draw resistance is little, and it is more stable that degree of vacuum is difficult for bounce-back; The forvacuum time is short, the ultimate vacuum height, and energy consumption is low.
Below in conjunction with a specific embodiment; model utility is further understood in exemplary illustration and help; but embodiment's detail only is for model utility is described; do not represent model utility design whole technological schemes down; therefore should not be construed as the technological scheme qualification total to model utility, some do not depart from the unsubstantiality of model utility design and change In the view of the technician; for example change or replace, all truely use novel protected scope so that technical characteristics with same or similar technique effect is simple.
