The vacuum buffer tank comprises a tank body, wherein a vacuum distilling apparatus is connected to one side of the lower part of the tank body through a first pipeline, a first valve is arranged on the first pipeline, the upper part of the tank body is connected to a vacuum pump through a second pipeline, a second valve is arranged on the second pipeline, a third pipeline is arranged on the lower part of the tank body, a third valve is arranged on the third pipeline, a receiver is arranged below the third pipeline, a condensate water layer is arranged on the periphery of the tank body, a clapboard is arranged in the inner hollow cavity of the tank body, the clapboard is located above the first pipeline, and micropores are formed in the clapboard. The vacuum buffer tank provided by the utility model has an airflow buffer effect to effectively stabilize the system pressure, reduces the possibility of stream entering the vacuum pump to prolong the service life of the vacuum pump and can absolutely prevent air leakage or prevent water from being backflushed to the vacuum distilling apparatus.
Description
Technical field
The utility model belongs to chemical field, is specifically related to a kind of vacuum buffer tank.
Background technology
Vacuum distillation plant is one of most popular equipment of numerous industries such as chemical industry, medicine, and in case of having a power failure or during the fortuitous event such as operate miss, the water of vavuum pump can pour in down a chimney and enters distillation system and contaminated material or water and material reaction and cause security incident.Existing is generally between surge tank and vavuum pump, to add the measure of check-valves, but this measure can only delay definitely to stop gas leakage or water to spring back over surge tank.
Summary of the invention
The purpose of this utility model is to provide a kind of vacuum buffer tank, has the effect of buffer gas flow, has reduced the chance that steam enters vavuum pump, and the life-span of having improved vavuum pump, once during accidental power failure can definitely stop gas leakage or water to spring back over vacuum distillation plant.
Vacuum buffer tank of the present invention, comprise tank body, bottom one side of tank body connects vacuum distillation plant by the first pipeline, the first valve is set on the first pipeline, tank body top connects vavuum pump by second pipe, the second valve is set on second pipe, tank body lower part arranges the 3rd pipeline, the 3rd valve is set on the 3rd pipeline, there is receiver the 3rd pipeline below, and tank body is arranged with condensed water layer outward, in tank interior cavity, is provided with dividing plate, dividing plate is positioned at the first pipeline top, and aperture is set on dividing plate.
Tank body top arranges measuring cell.
During use, the first valve and the second valve open, the 3rd valve closing, under the effect of vavuum pump, vacuum distillation plant distills, although vacuum distillation arranges inside, there is condenser pipe, under the effect of vavuum pump, still have steam to be drawn out of vacuum distillation plant, cause waste, once and steam enters after vavuum pump, can cause damage to vavuum pump, reduce the life-span of vavuum pump.At tank body, be arranged with condensed water layer outward, the steam that is drawn out of vacuum distillation plant enters into surge tank, and condensation under the effect of condensation water layer has reduced the chance that steam enters vavuum pump.In tank interior cavity, be provided with dividing plate, dividing plate is positioned at the first pipeline top, and aperture is set on dividing plate, plays the effect of buffer gas flow, effectively systems stabilisation pressure.Once have a power failure suddenly, the first valve is closed at once, guarantee that vacuum distillation plant is also in vacuum state, and after the second valve and the 3rd valve opening, can guarantee that the part being connected with vavuum pump is in emptying state, and can get rid of in time the liquid that in surge tank, vacuum distillation plant brings, liquid enters receiver, can recycle, avoid waste, and prevent the material environment that decontaminates.On tank body top, measuring cell is set, understands in time the pressure of surge tank tank interior.
Compared with prior art, the utlity model has following advantage:
(1) once during accidental power failure can definitely stop gas leakage or water to spring back over vacuum distillation plant.
(2) chance that steam enters vavuum pump, the life-span of having improved vavuum pump have been reduced.
(3) the utility model has the effect of buffer gas flow, effectively systems stabilisation pressure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-tank body, 2-the first pipeline, 3-measuring cell, 4-the second valve, 5-second pipe, 6-vavuum pump, 7-tank body, 8-condensation water layer, 9-dividing plate, 10-aperture, 11-the 3rd valve, 12-receiver, 13-the 3rd pipeline, 14-the first valve.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further.
As shown in Figure 1, comprise tank body 7, bottom one side of tank body 7 connects vacuum distillation plant 1 by the first pipeline 2, the first valve 14 is set on the first pipeline 2, tank body 7 tops connect vavuum pump 6 by second pipe 5, the second valve 4 is set on second pipe 5, tank body 7 bottoms arrange the 3rd pipeline 13, the 3rd valve 11 is set on the 3rd pipeline 13, there is receiver 12 the 3rd pipeline below, and tank body 7 is outer is arranged with condensed water layer 8, in tank body 7 internal cavities, is provided with dividing plate 9, dividing plate 9 is positioned at the first pipeline 2 tops, and aperture 10 is set on dividing plate 9.Tank body 7 tops arrange measuring cell 3.
During use, the first valve 14 and the second valve 4 are opened, and the 3rd valve 11 is closed, under the effect of vavuum pump 6, vacuum distillation plant 1 distills, although vacuum distillation arranges 1 inside, there is condenser pipe, under the effect of vavuum pump 6, still have steam to be drawn out of vacuum distillation plant 1, cause waste, once and steam enters after vavuum pump 6, can cause damage to vavuum pump 6, reduce the life-span of vavuum pump 6.Outside tank body 7, be arranged with condensed water layer 8, the steam that is drawn out of vacuum distillation plant 1 enters into surge tank, and condensation under the effect of condensation water layer 8 has reduced the chance that steam enters vavuum pump 6.In tank body 7 internal cavities, be provided with dividing plate 9, dividing plate 9 is positioned at the first pipeline 2 tops, and aperture 10 is set on dividing plate 9, plays the effect of buffer gas flow, effectively systems stabilisation pressure.Once have a power failure suddenly, the first valve 14 is closed at once, guarantee that vacuum distillation plant 1 is also in vacuum state, and after the second valve 4 and the 3rd valve 11 unlatchings, can guarantee that the part being connected with vavuum pump 6 is in emptying state, and can get rid of in time the liquid that in surge tank, vacuum distillation plant 1 brings, liquid enters receiver 12, can recycle, avoid waste, and prevent the material environment that decontaminates.On tank body 7 tops, measuring cell 3 is set, understands in time the pressure of surge tank tank interior.
