Abstract
Provided is an air extractor for a turbo generator set condenser. The air extractor includes a water jet air ejector (1), which is communicated with the turbo generator set condenser, of an air tube, and a water jet pump (5) communicated with the water jet air ejector (1) and supplying water sources to the water jet air ejector (1). The air extractor provided uses water rather than water steam as a working medium, thereby improving the stability of the medium work pressure of the water jet air ejector (1), guaranteeing the stability of the vacuum degree of the turbo generator set condenser, as well as guaranteeing the reliability of the work performance of a turbo generator set.
Description
Technical field
The utility model relates to a kind of air extractor, especially a kind of air extractor for Turbo-generator Set condenser.
Background technology
When Turbo-generator Set is worked, keeping the vacuum of Turbo-generator Set condenser is a necessary condition, otherwise just affected the service behaviour of Turbo-generator Set, therefore the air extractor for Turbo-generator Set condenser is a kind of important generating parts, in existing fertilizer, along with agriculture modern production, in agricultural fertilizer, generally used the air extractor for Turbo-generator Set condenser, but at the existing air extractor for Turbo-generator Set condenser, stream-jet ejector operation is complicated, first to drive the main air ejector of secondary, adjust and maintain vapour pressure at 1.37MPa, drive again the main air ejector of one-level, adjust and maintain vapour pressure at 0.39MPa, also to drive auxiliary air ejector, adjust vapour pressure simultaneously and maintain 1.17Mpa, when condenser vacuum reaches 0.067MPa, just stop using and assist air ejector.The working medium of stream-jet ejector consumption in service is steam, although reclaimed heat with bleeder heater, this part heat has squeezed low-temperature heater and drawn gas, and increased amount of work, and the efficiency of drawing gas of low-temperature heater is low, and the loss causing is very large.State in bleeder heater is influential to the characteristic of air ejector.The dirty impact of heat exchanger tube of bleeder heater is conducted heat, and during steam side pressure rise, reduce the ability to work of air ejector; The corrosion of bleeder heater pipe is revealed, and also will affect the service behaviour of air ejector.Stream-jet ejector is due to larger wasted work and unsettled operating condition, steam pressure and air ejector cooling water flow, temperature fluctuation, the working conditions that air ejector is hydrophobic etc. all can impact and the shortcoming such as stream-jet ejector has that complex structure, the cost of overhaul are large, operation inconvenience, wasted work are large unit operation, can not meet power unit in economic operation.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of air extractor for Turbo-generator Set condenser, has therefore guaranteed the reliability of Turbo-generator Set service behaviour.
For achieving the above object, the technical scheme that the utility model is taked is: include and have the water jet air ejector of the air hose being communicated with Turbo-generator Set condenser, be communicated with water jet air ejector and be used to water jet air ejector that the water-jet pump at water source is provided.
Start water-jet pump, water in pond is injected in water jet air ejector, at water jet air ejector, produce vacuum, air hose by water jet air ejector is realized vacuum in Turbo-generator Set condenser, owing to having designed water jet air ejector and water-jet pump, make water as working media, do not re-use water vapour as working media, improved the stability of the medium operating pressure of water jet air ejector, guarantee the stability of the vacuum of Turbo-generator Set condenser, therefore guaranteed the reliability of Turbo-generator Set service behaviour.
The utility model has designed, also include efferent duct, drainpipe, leaving velocity exhaust tube and pond, the water inlet port of water jet air ejector is set to be communicated with water-jet pump water outlet port by water inlet pipe, water-jet pump water inlet port is arranged in pond, the water outlet port of water jet air ejector is set to be communicated with efferent duct, efferent duct is set to be communicated with drainpipe, drainpipe is arranged in pond, the air hose of water jet air ejector is set to be communicated with Turbo-generator Set condenser, on the connecting portion of drainpipe and efferent duct, is provided with the leaving velocity exhaust tube being communicated with drainpipe.
The utility model has designed, and the diameter of drainpipe is set to be greater than the diameter of efferent duct.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Fig. 1 is an embodiment of the present utility model, illustrate by reference to the accompanying drawings the present embodiment, include water jet air ejector 1, efferent duct 2, drainpipe 3, leaving velocity exhaust tube 6, pond 4 and water-jet pump 5, the water inlet port of water jet air ejector 1 is set to be communicated with water-jet pump 5 water outlet ports by water inlet pipe, water-jet pump 5 water inlet ports are arranged in pond 4, the water outlet port of water jet air ejector 1 is set to be communicated with efferent duct 2, efferent duct 2 is set to be communicated with drainpipe 3, drainpipe 3 is arranged in pond 4, the air hose of water jet air ejector 1 is set to be communicated with Turbo-generator Set condenser, on the connecting portion of drainpipe 3 and efferent duct 2, be provided with the leaving velocity exhaust tube 6 being communicated with drainpipe 3.
In the present embodiment, the diameter of drainpipe 3 is set to be greater than the diameter of efferent duct 2.
Start water-jet pump 5, the water in pond 4 is injected in water jet air ejector 1, at water jet air ejector 1, produce vacuum, by the air hose of water jet air ejector 1, in Turbo-generator Set condenser, realize vacuum.
The utlity model has lower feature:
1, owing to having designed water jet air ejector 1 and water-jet pump 5, make water as working media, do not re-use water vapour as working media, improved the stability of the medium operating pressure of water jet air ejector 1, guarantee the stability of the vacuum of Turbo-generator Set condenser, therefore guaranteed the reliability of Turbo-generator Set service behaviour.
2,, owing to having designed efferent duct 2, drainpipe 3 and leaving velocity exhaust tube 6, the draining of more convenient water jet air ejector 1 and work start.
3, owing to having designed efferent duct 2 and drainpipe 3, guarantee the jetting performance of water jet air ejector 1, improved the service behaviour of water jet air ejector 1.
In the air extractor technical field for Turbo-generator Set condenser; Have the water jet air ejector 1 of the air hose being communicated with Turbo-generator Set condenser, be communicated with water jet air ejector 1 and be used to water jet air ejector 1 to provide the technology contents of water-jet pump 5 at water source all in protection domain of the present utility model every including.
