Abstract
The utility model relates to an improved structure of a vacuum gas and liquid separator. The top end and the bottom of a cylinder body are sealed by a cylinder cover and a bottom cover, the upper side wall of the cylinder body is provided with an air inlet pipe and an air suction pipe, a drainage pump is positioned at the lower part in the cylinder body, and a vacuum backstop is arranged between a drainage pipe and a drainage opening. The utility model causes that gas and liquid in a vacuum pumping system are effectively separated, and accumulated liquid can be drained under the condition that the vacuum of the system is not broken, the continuous running of the vacuum pumping system can be maintained, and the work efficiency is high.
Description
The utility model relates to the improvement of vacuum gas-liquid separator structure.
In using the vacuum technique system, in many instances, the gas that is evacuated all is mixed with liquid (water) and other impurity, and can not directly enter in the vavuum pump.For example: the dewatering of pulp of the vacuum cup that glass technology processing is used, vacuum distillation, vacuum drying, papermaking etc.
In above production link, what generally use is that water-ring vacuum pump vacuumizes.The vacuum of this class vavuum pump and efficient are all lower, and often influence operate as normal because of the pendular ring line clogging in the running; And the gas-liquid separation device that uses in case of necessity, generally can only intermitten service, promptly isolated liquid must be shut down when a certain amount of, destroys system vacuum and liquid could be discharged.
This novel purpose provides a kind of novel evacuated gas-liquid separation device, the gas that is evacuated in the system that enters before the vavuum pump is effectively separated with liquid (impurity), and when separator residual when a certain amount of, can discharge not destroying under the vacuum state condition, make vacuum system can keep the state of continuous operation.
The purpose of this utility model is achieved in that the top of its cylindrical shell and bottom are sealed by cover and bottom respectively, and the upper side wall of cylindrical shell leaves air inlet pipe and exhaust tube, and dredge pump is positioned at the bottom of cylindrical shell, and blow-off pipe is to the vacuum holdback is housed between the sewage draining exit.After the working medium of being taken out entered cylindrical shell by air inlet pipe, gas separated voluntarily with liquid, and gas is taken away by vavuum pump by exhaust tube, and hydrops is then discharged cylindrical shell by dredge pump through blow-off pipe and vacuum holdback when acquiring a certain degree.During this time, the vacuum of work system not only can not descend, and can rise, and system effect is better than original device.
Be further described below in conjunction with the structure of accompanying drawing to the vacuum gas-liquid separator: the top of cylindrical shell (5) and bottom are respectively by cover (2) and bottom (8) sealing, cover (2) and bottom (8) can be dismantled, be convenient to the cylindrical shell cleaning, vacuum meter (4) is equipped with in the upper side wall of cylindrical shell (5) outside, and leaves to vacuum user's air inlet pipe (A) with to the exhaust tube (B) of vavuum pump.Dredge pump (7) is positioned at the bottom of cylindrical shell (5), link to each other with the blow-off pipe (10) that reaches cylindrical shell (5) bottom by cover (2), liquid-level probe (6) is fixed on the blow-off pipe (10) by two stands (11), blow-off pipe (10) is equipped with vacuum holdback (9) between the sewage draining exit (D), the last dignity that blow-off pipe (10) is positioned at cylindrical shell (5) has vacuum balancing orifice (C), the lead-in wire of dredge pump (7) and liquid-level probe (6) is introduced by the wire insulation seal cover (1) that is positioned at cover (2), labyrinth type condensation cage (3) is housed in the cylindrical shell (5), it is positioned at vacuum meter (4), the below of exhaust tube (B) and vacuum balancing orifice (C), the top of air inlet pipe (A) and liquid-level probe (6).Its operation principle is: when by the working medium of being taken out after the air inlet pipe (A) to the vacuum user enters cylindrical shell (5), because of its volumetric expansion, gas-liquid is separated voluntarily, and liquid (impurity) is deposited on the bottom, and gas passes through labyrinth type condensation cage (3) after exhaust tube (B) is taken away by vavuum pump.When liquid level line (H) is gone up in deposit liquid arrival, the dredge pump (7) that is located in the vacuum cylindrical shell starts, liquid is discharged from sewage draining exit (D) through vacuum holdback (9), the interior vacuum of tube this moment is not only destroyed, raise on the contrary, when liquid level was extracted into down liquid level line (L), dredge pump (7) quit work.
After using this device, used the occasion of water-ring vacuum pump in the past, can use the higher vavuum pump of vacuum (as rotary-vane vaccum pump) instead, operating efficiency improves greatly.
Claims (3)
1. vacuum gas-liquid separator, top of its cylindrical shell (5) and bottom are respectively by cover (2) and bottom (8) sealing, leave above the upside of cylindrical shell (5) to vacuum user's air inlet pipe with to the exhaust tube of vavuum pump, it is characterized in that: dredge pump (7) is positioned at the bottom of cylindrical shell, and blow-off pipe (10) is to vacuum holdback (9) is housed between the sewage draining exit.
2. vacuum gas-liquid separator according to claim 1 is characterized in that: be positioned at inner blow-off pipe (10) top of cylindrical shell (5) and have the vacuum balancing orifice.
3. vacuum gas-liquid separator according to claim 1 and 2 is characterized in that: labyrinth type condensation cage (3) is housed in the cylindrical shell (5).
