Abstract
The utility model provides a flash and condensing device preventing air from entering. The flash and condensing device comprises a flash tank with a flash steam outlet and a high-pressure saturated water inlet, a condensate water tank below the flash tank and a sealing pipe, wherein the upper end of the condensate water tank is connected with the flash tank, and the lower end of the sealing pipe is arranged in the condensate water tank. The flash and condensing device is characterized in that a liquid level meter is arranged on the condensate water tank, the upper portion of the condensate water tank is connected with a water supply pipe through a valve, and the liquid level meter and the valve are connected with a controller through guide wires respectively. When a water level is too low, a water supply valve is opened through the controller to supply water, the problems that due to the fact that the water level of the condensate water tank is too low and external air is made to enter the flash tank through the sealing pipe, and then enters a turbine along with flash steam, the vacuum degree of the condenser of the turbine is lowered, the working efficiency of the turbine is influenced, and even the turbine is shut down are solved, energy consumption is effectively lowered, and the flash and condensing device has the advantages of being simple in structure, high in reliability, convenient to mount and maintain and the like.
Description
Technical field
The utility model relates to a kind of flash distillation, condensing unit, and particularly a kind of flash distillation, condensing unit, belong to steam turbine flash distillation filling device design and manufacturing technology field.
Background technology
Flash evaporation technology is that the high temperature saturation water in boiler enters pressure decreased after flash tank, thereby converts low-pressure saturated steam to, the process that then enters steam turbine and steam turbine is done manual work.And can generate the low pressure saturation water in this transfer process, these low pressure saturation waters enter condensation water tank, and by water pump, again pump into the use of boiler warming circulating.Because present condensation water tank often can be too low because of water level; and make extraneous air enter flash tank through sealed tube, and follow flash steam and enter steam turbine, cause steam turbine condenser vacuum degree to reduce; thereby cause turbine efficiency and power output significantly to reduce, finally make steam turbine out of service.This will bring huge loss to enterprise, also increase consumption and the waste of the energy simultaneously.Therefore be necessary prior art is improved.
Summary of the invention
Too low for solving existing flash tank internal cause condensation water tank water level, easily enter air steam turbine condenser vacuum degree is reduced, force the problem of its shutdown, the utility model provides a kind of flash distillation, condensing unit that prevents that air from entering.
the utility model is completed by following technical proposal: a kind of flash distillation that prevents that air from entering, condensing unit, comprise the outlet of band flash steam, the flash tank of high pressure saturation water entrance, be positioned at the condensation water tank of flash tank below, its upper end is connected with flash tank, lower end is placed in the sealed tube of condensation water tank, it is characterized in that condensation water tank is provided with liquid level gauge, condensation water tank top connects filling pipe by valve, liquid level is taken into account valve and is connected with controller by wire respectively, with the liquid level of convenient condensation water tank during lower than alarm liquid level, by the controller Open valve, with to the condensation water tank moisturizing, when liquid level during higher than alarm liquid level, by the controller valve-off, stop to the condensation water tank moisturizing, guarantee normal condensation water tank liquid level.
It is commercial product that described controller, liquid level are taken into account valve.
the utlity model has following advantages and effect: adopt such scheme, liquid level gauge namely is set in condensation water tank, be used for the water level in the monitoring water tank, open the moisturizing valve by controller when water level is too low, carry out moisturizing, solved because of the condensation water tank water level too low, and make extraneous air enter flash tank through sealed tube, and then with flash steam, enter steam turbine, cause steam turbine condenser vacuum degree to reduce, affect the steam turbine operating efficiency, even cause the problems such as halt turbines, and effectively reduce energy consumption, the utlity model has simple in structure, reliability is high, the advantages such as installation and maintenance are convenient.Be desirable flash distillation, a condensing unit in fact.
Description of drawings
Fig. 1 is the structure chart of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, the utility model provides prevents flash distillation, the condensing unit that air enters, comprise the flash tank 4 with flash steam outlet 5, high pressure saturation water entrance 3, flash steam outlet 5 is connected with steam turbine by pipeline 6, be positioned at the condensation water tank 3 of flash tank 4 belows, its upper end is connected with flash tank 4, lower end is placed in the sealed tube 7 of condensation water tank 3, condensation water tank 3 is provided with liquid level gauge 1, condensation water tank 3 tops connect filling pipe 9 by valve 8, liquid level gauge 1 and valve 8 are connected with controller by wire respectively, and controller, liquid level gauge 1 and valve 8 are commercial product.
