Abstract
The utility model discloses a device capable of monitoring air content in a condenser. The device capable of monitoring the air content in the condenser comprises the condenser, a pressure measuring element and a temperature measuring element. The pressure measuring element and the temperature measuring element are arranged on a pipeline of an air sucking opening of the condenser. The monitoring device can accurately monitor the air content in the condenser and then judges whether air has influence on performance of the condenser, and if the air content is higher than a certain value, the performance of the condenser is affected by the air, and conversely, the performance of the condenser is not affected by the air.
Description
Technical field
The utility model belongs to condensing steam turbine generator group performance parameter monitoring field, is specifically related to a kind of device of monitoring condenser Air content.
Background technology
Condensing steam turbine generator group condenser Air aggregate amount produces considerable influence to the condenser heat exchange, and then has influence on the unit operation vacuum.
At present, the rate of vacuum drop that the technical staff all adopts the vacuum tightness test to record is judged the size of leaking-in air amount, and whether heat exchange exerts an influence to condenser to judge air with this.Find by research, rely on the vacuum tightness result can't judge that at all air is to the influence degree of Performance of Condensers; Defective such as the part of generating units vacuum tightness, but leaked-in air does not affect the condenser heat exchange, and on the contrary, some unit vacuum tightness level is outstanding, but leaked-in air produces larger impact to the condenser heat exchange.
Summary of the invention
The purpose of this utility model is to provide a kind of can accurately monitor air content, thereby judge that air is to the influence degree of Performance of Condensers, and then provide foundation for the operations staff of power plant takes corresponding technical measures, reach and eliminate and reduce air to the device of the monitoring condenser Air content of the impact of Performance of Condensers.
For achieving the above object, the technical solution adopted in the utility model is: comprise condenser and be installed in pressure measuring element and temperature-measuring element on the Condenser Extraction mouth pipeline.
Two outlets of described Condenser Extraction mouth pipeline all are equipped with pressure measuring element and temperature-measuring element.
Described pressure measuring element and temperature-measuring element are installed on the condenser next-door neighbour exhaust pipeline.
Thereby monitoring device of the present utility model can be monitored out condenser Air content and be judged whether air is influential to Performance of Condensers, if air content exceeds certain numerical value, then Performance of Condensers is subjected to air impact, otherwise without impact accurately.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to Fig. 1, the utility model comprises condenser 1 and is installed in pressure measuring element 2 and temperature-measuring element 3 on 1 two in the condenser outlet next-door neighbour exhaust pipeline 4.
The utility model is by ad-hoc location setting pressure measuring cell and temperature-measuring element on finding time the gas port pipeline at the condensing-type thermal power unit condenser, and the pressure and temperature value actual measurement obtains air content by analytical calculation.
Condenser and exhaust systematic comparison are huge, and the air content of diverse location is different, and how choosing representational position, to carry out parameter measurement be one of key technology of this device.By a large amount of research, determine namely be close to setting pressure measuring cell 2 and temperature-measuring element 3 on the exhaust pipeline on the Condenser Extraction pipe.
After the parameter measurement, adopt the physical characteristic of Dalton's law (of partial pressures) and saturated vapor to determine air content.Computing formula is as follows:
Wherein: P is the gross pressure of the interior saturated vapor of exhaust pipeline and air mixture;
T is the temperature of the interior saturated vapor of exhaust pipeline and air mixture;
F (t) asks the function of saturation pressure for known saturated vapor temperature.
The utility model can be real-time the monitoring air content, for judging air, the technical staff of power plant provides benchmark and method to impact and the degree of Performance of Condensers, thereby can take corresponding technical measures to eliminate the impact of air on Performance of Condensers, reach energy-saving and cost-reducing purpose.
