Abstract
The utility model discloses a full low frame steam jet vacuum system, which comprises a multistage steam ejector pump and at least two condensers composed of main condensers and accessorial condensers, wherein a water storage tank is arranged below each condenser. The utility model is characterized in that the water storage tank of each of the main condensers and the water storage tank of each of the accessorial condensers are connected through a siphon tube. Because the utility model adopts the system, the utility model has the advantages of ground installation, no platform capital cost, simple installation, convenient operation, reliable operation, less energy consumption, etc. In addition, the utility model adopts the siphon tube and a self-absorption water supplying method, so a water pump is saved, thus saving investment, reducing maintenance and saving operating cost.
Description
Technical field
The utility model relates to a kind of steam jet vacuum system, especially relates to a kind of all low frame steam jet vacuum system.
Background technique
At present, existing steam jet vacuum system mounting type has overhead and is partly overhead.For condensed water is successfully discharged under vacuum state, overhead vacuum system is used the platform more than 10 meters, overcomes barometric pressure and discharges with the water column more than 10 meters; Half overhead vacuum system has reduced some rice with 10 meters platforms, and under platform, be equipped with the centrifugal water pump that suitable height is inhaled journey, can draining not collaborate mutually again for the assurance condenser, import header tank with U-shaped pipe or similar structure between condenser, the dress centrifugal water pump is discharged condensed water under the header tank.Overhead system steam jet vacuum system platform capital cost height, operation inconvenience can't realize from sucting water simultaneously; Half overhead system steam jet vacuum system, capital cost is still high, can't realize floor mounted, seal request to centrifugal water pump is very tight simultaneously, in case when leaking air, condensed water can't be discharged, and can cause the fluctuations of vacuum in the condenser, cause the fluctuations of vacuum of whole steam jet vacuum system from face, reduced the reliability and the Security of vacuum system.
Summary of the invention
The purpose of this utility model just be to provide a kind of can complete surface-based all low frame steam jet vacuum system.
The purpose of this utility model can realize by following measure:
The utility model comprises the multistage steam jet pump and by at least two condensers that main condenser, auxiliary condenser are formed, is respectively arranged with water storage box below each condenser that the water storage box of described main condenser and auxiliary condenser is connected by syphon tube.
The utility model is equipped with submersible pump in described its main condenser water storage box, and in the waste pipe of submersible pump outside the main condenser water storage box one-way valve is housed.Described syphon tube is L shaped shape or other shapes.
The utility model has following advantage owing to adopt said system:
1, all low frame steam jet vacuum system floor mounted, no platform capital cost, more convenient operation.
2, by the vacuum difference (promptly having pressure reduction) in each condenser, the condensed water of auxiliary condenser is sucked in the main condenser by syphon tube, and the steam that main ejector enters main condenser is carried out cooling just, the utilization ratio height of Gu Shui.
3, the submersible pump that one-way valve will be housed is installed in the water storage box of main condenser, because of submersible pump has only lift, do not inhale journey, still can proper functioning after the floor mounted, and one-way valve can guarantee termination of pumping the time water can not flow backwards, submersible pump can only cause the efficient of water pump to reduce if any leaking simultaneously, and can not cause fluctuations of vacuum, so drainage system is safer, stable and reliable.
Owing to adopt syphon tube and self-priming to supply water, saved a charging pump in the utility model, both thrifty investment has reduced maintenance, has saved operating cost again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is explained in detail below in conjunction with drawings and Examples:
As shown in the figure, the utility model comprises multistage steam jet pump 3,5,7 and at least two condensers being made up of main condenser 4, auxiliary condenser 8, be respectively arranged with water storage box below each condenser, it is characterized in that: the water storage box of described main condenser and auxiliary condenser is connected by syphon tube.In described its main condenser water storage box 9, submersible pump 1 is installed, and in the waste pipe of submersible pump 1 outside main condenser water storage box 9, one-way valve 2 is housed.Described syphon tube 6 is L shaped shape, also can be other suitable shapes.
Specifically: adopting syphon tube is for the pressure difference between the water storage box that utilizes main condenser and auxiliary condenser is drawn onto the water in the water storage box of auxiliary condenser in the water storage box of main condenser, in view of the above, also can adopt other to have the Placement of same effect.When adopting three or more water storage boxs, the water in the one-level water tank of back can be drawn onto in the previous stage water tank step by step, finally arrive in the main water box; Also can be directly connected in the main water box.Working principle of the present utility model is as follows: all low frame steam jet vacuum system is made up of the water storage box of multistage steam jet pump and two or more condenser and condenser below, because the vacuum difference (promptly having pressure reduction) between condenser, rely on vacuum poor (being pressure reduction), link to each other by syphon tube between the water storage box of main condenser and auxiliary condenser; The condensed water of auxiliary condenser sucks in the main condenser by syphon tube, and the steam that main ejector enters main condenser carried out cooling just, condensed water converges to water storage box, by submersible pump water is delivered to cooling tower again, owing to be floor mounted, the water intake of condenser is not high, in the condenser vacuum is arranged again simultaneously, gets final product by self-priming so cooling is supplied water.
In conjunction with the accompanying drawings: the steam-expelling port of main steam jet pump 3 enters main condenser 4 condensations, and the surplus vapour that is not condensed is taken away by an auxilliary jet pump 5 and entered auxiliary condenser 8 condensations, and the surplus vapour that is not condensed is at last taken away emptying by auxilliary two jet pumps 7.A water storage box 9 and 10 are arranged respectively below main condenser 4 and auxiliary condenser 8, because the vacuum height in the main condenser 4, by syphon tube 6 condensed water in the water storage box 10 is sucked in the water storage box 9, and the steam that main ejector enters main condenser carried out cooling just, deliver to cooling tower 12 by submersible pump 1 and one-way valve 2 again, fall into water cooling pond 11, deliver to the water intake of major-minor condenser by self-straw 13 respectively.The main injection pump 3 here can be single-stage pump, also can be multistage supercharging pumps in series.
