Abstract
The utility model discloses an ejector vacuum pump system with two-stage buffer, which comprises an ejector, a water tank and a circulating water pump. An outlet of the circulating water pump is communicated with an inlet of the ejector; an inlet of the water tank is connected with an outlet of the ejector; a water outlet of the water tank is communicated with an inlet of the circulating water pump; and a vacuum suction port of the ejector is sequentially connected with a buffer tank and a secondary buffer tank. The ejector of the ejector vacuum pump system is horizontally positioned above the water tank, so that space economization is benefited, and the ejector vacuum pump system is suitable for being mounted and used in a place with a limited space. In addition, use effect is improved by means of the two-stage buffer.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, relates in particular to a kind of vacuum ejector vacuum pump system that is used for.
Background technique
Water jet pump is the chemical industry equipment of using always, and the critical piece that is used to form vacuum is a sparger, auxiliary water tank and circulating water pump in addition.
In sparger, have the working medium water of certain pressure, spray at a high speed to suction chamber by nozzle, the pressure of water can be become kinetic energy, form high-speed jet; Gas in the suction chamber is forced to carry with it by high-speed jet and is mixed, and forms gas-liquid mixed stream, enters Diffuser, thereby suction chamber pressure is reduced, form vacuum, in the extending section of Diffuser, the kinetic energy of mixed jet changes the pressure energy into, speed reduces pressure and raises, and gas is further compressed, outside the water excavationg pump, air-water separation in water tank, gas release is gone into atmosphere, and water is by the water pump cycling and reutilization, and going round and beginning again reaches the purpose that vacuumizes.
Sparger of the prior art mostly is an injection water straight down, and the upright sparger of arranging occupies bigger space, and limited place is unfavorable for installing and using in the space, generally only adopts a knock out drum in addition, and the effect of buffering is bad.
The model utility content
The utility model provides a kind of space, water injection vacuum pump system easy to use of saving, and is suitable for the place limited in the space and installs and use, and has also improved cushioning effect.
A kind of ejector vacuum pump system that has the two poles of the earth buffering, comprise sparger, water tank and circulating water pump, the circulating water pump outlet is communicated with the sparger inlet, tank entry is accepted the sparger outlet, water outlet of water tank is communicated with the circulating water pump inlet, and the vacuum suction port of described sparger is connected with baffle-box and level 2 buffering jar in turn.
Described sparger is positioned at the water tank top.The water tank top that is positioned at of sparger level helps saving the space.
Be respectively equipped with vacuum gauge on baffle-box and the level 2 buffering jar, the level 2 buffering tank top has the vacuum house steward, is used to insert the vacuum line of entire reaction system.
Being positioned at above the water tank of the sparger level of the utility model ejector vacuum pump system helps saving the space, is suitable for place installation and the use limited in the space.Buffering by the two poles of the earth has improved using effect in addition.
Description of drawings
Fig. 1 has the structural representation of the ejector vacuum pump system of the two poles of the earth buffering for the utility model is a kind of.
Embodiment
Referring to accompanying drawing, a kind of ejector vacuum pump system that has the two poles of the earth buffering of the utility model, comprise sparger 1, water tank 2 and circulating water pump 3, circulating water pump 3 outlets are communicated with sparger 1 inlet, the inlet of water tank 2 is accepted sparger 1 outlet, the water outlet of water tank 2 is communicated with the inlet of circulating water pump 3, and the vacuum suction port of sparger 1 is communicated with baffle-box 7.
Sparger 1 level be positioned at water tank 2 tops, help saving the space.Water tank 2 bottom of an end longitudinally has outlet, and sparger 1 outlet is accepted at the other end top.Be connected with stiffening plate 10 between horizontal two sidewalls of water tank 2, to improve the bulk strength of water tank 2.
The position that water tank 2 is accepted sparger outlet is provided with the dividing plate 9 of vertical layout, and dividing plate 9 upper edges are concordant with the upper edge of water tank 2, leave circulating water channel between the bottom surface of dividing plate 9 lower edges and water tank 2.Adopting dividing plate 9 to help forming rational water cycle flows to.
Baffle-box 7 is connected with level 2 buffering jar 4 by pipeline, is respectively equipped with vacuum gauge 8 and vacuum gauge 5 on baffle-box 7 and the level 2 buffering jar 4, and level 2 buffering jar 4 tops are vacuum house steward 6.
Being positioned at above the water tank of the sparger level of the utility model ejector vacuum pump system helps saving the space, is suitable for place installation and the use limited in the space.Form the rational water cycle flow direction by dividing plate is set in addition, improved using effect.
Claims (2)
1. one kind has the ejector vacuum pump system that the two poles of the earth are cushioned, comprise sparger, water tank and circulating water pump, wherein said circulating water pump outlet is communicated with the sparger inlet, tank entry is accepted the sparger outlet, water outlet of water tank is communicated with the circulating water pump inlet, it is characterized in that the vacuum suction port of described sparger is connected with baffle-box and level 2 buffering jar in turn.
2. the ejector vacuum pump system that has the two poles of the earth buffering as claimed in claim 1 is characterized in that, is respectively equipped with vacuum gauge on baffle-box and the level 2 buffering jar.
