Abstract
The utility model relates to a cooling device for a vacuum system. The cooling device comprises a condenser, a circulating water pool, a water-jet pump, a water-jet vapor extractor, a water-jet tank and a heat exchanger, wherein water inlet and outlet pipes of the vapor extractor are communicated with the circulating water pool; water inlet and outlet of the water jet pump are communicated with the water-jet tank; the water outlet of the water-jet pump and a pump-out pipeline of the condenser are communicated with the inlet of the water-jet vapor extractor; and the heat exchanger is distributed in a pipeline from the condenser to the inlet of the water-jet vapor extractor. According to the cooling device for the vacuum system, vapor extracted in a vacuum pipeline is condensed into water after being cooled, the vapor quantity is reduced, thermal load of the vapor extractor is reduced, and heat carried by working water of the water-jet vapor extractor is reduced, so that the water temperature is reduced, vaporization at the nozzle is prevented, and the efficiency of the vapor extractor is improved.
Description
Technical field
The utility model belongs to the turbine vacuum system technical field, especially a kind of vacuum system cooling unit of steam turbine.
Background technique
The jetting vapor extractor is that incoagulable gas in the turbine condenser is extracted out; But the steam flow in the normal operation period suction will become hundred times of ground to surpass air quantity, and these vapor (steam) temperatures probably have 50-60 degree, after being sucked by vapor extractor; Cause that jetting case water temperature raises; The vaporization at vapor extractor nozzle place reduces vapor extractor efficient, causes that vacuum slowly descends.
The model utility content
The purpose of the utility model is to overcome the shortcoming of above-mentioned existing technology, and a kind of vacuum system cooling unit is provided, and can the condense steam of vacuum line of this device reduces jetting case water temperature with this, prevents the vaporization of vapor extractor nozzle place, improves vapor extractor efficient.
The purpose of the utility model solves through following technological scheme:
This vacuum system cooling unit; Comprise vapour condenser, circulating water pool, water-jet pump, jetting formula vapor extractor, jetting case and heat exchanger; The turnover water pipe of said vapour condenser is communicated with circulating water pool; The intake-outlet of water-jet pump is communicated with the jetting case, and the water outlet of said water-jet pump and the pump-line of vapour condenser are communicated with the import of jetting formula vapor extractor; Said heat exchanger is arranged in vapour condenser to the jetting vapor extractor inlet ductwork.
The water outlet of above-mentioned water-jet pump is connected with heat exchanger, and heat exchanger is connected with the condenser vacuum pipeline, and the import and export of heat exchanger are communicated with extraneous cooling medium pipeline, and the hydrophobic and hot well of heat exchanger is communicated with.
After the vacuum system cooling unit of the utility model cools off the steam that in vacuum line, is aspirated; Condense into water, steam flow has reduced, and the heat load of vapor extractor has reduced; The heat that jetting case vapor extractor working water is taken away is few; Reduced water temperature, prevented vaporization, improved vapor extractor efficient at the nozzle place.
Description of drawings
Fig. 1 is that the equipment of the utility model connects schematic representation.
Wherein: 1 is circulating water pool; 2 is vapour condenser; 3 is heat exchanger; 4 is jetting formula vapor extractor; 5 is the jetting case; 6 is water-jet pump.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, the vacuum system cooling unit of the utility model comprises vapour condenser 2, circulating water pool 1, water-jet pump 6, jetting formula vapor extractor 4, jetting case 5 and heat exchanger 3.Wherein the turnover water pipe of vapour condenser 2 is communicated with circulating water pool 1, and the intake-outlet of water-jet pump 6 is communicated with jetting case 5, and the pump-line of the water outlet of water-jet pump 6 and vapour condenser 2 is communicated with the import of jetting formula vapor extractor 4; Heat exchanger 3 is arranged in vapour condenser 2 to the jetting vapor extractor inlet ductwork.The steam of jetting vapor extractor suction is through condensing like this, and temperature reduces greatly, reduces jetting case 5 water temperatures with this and prevents the vaporization of vapor extractor nozzle place, improves vapor extractor efficient.
The concrete annexation of the heat exchanger 3 of the utility model is: the water outlet of water-jet pump 6 is connected with heat exchanger 3; Heat exchanger 3 is connected with vapour condenser 2 vacuum lines; The import and export of heat exchanger 3 are communicated with extraneous cooling medium pipeline, and the hydrophobic and hot well of heat exchanger 3 is communicated with.
