Abstract
The utility model discloses an improved steam condenser vacuum system. The system comprises a steam condenser main pipe, wherein a steam ejector and a condenser are connected onto the steam condenser main pipe, the steam ejector pumps a steam and gas mixture in the steam condenser, power steam and water vapor in gases pumped from the steam condenser are condensed into water by the condenser and recovered into a hot well, and non-condensing gases in the system enter vacuum pump systems through the steam condenser main pipe for vacuum treatment; the vacuum pump systems are divided into two to three groups and connected onto the steam condenser main pipe in parallel, and each vacuum pump system consists of a water ring vacuum pump, a steam-water separator and a working solution heat exchanger. The system is wide in application range, is applicable to a vacuum pumping system which is adopted by a power plant and takes multiple groups of vacuum pumps as a main body at present, has the advantages of simple structure and low transformation cost and enables the vacuum degree of the steam condenser to still be kept in a high-level state all the time under a large-scale working condition.

Technical field
The utility model relates to a kind of to condenser vacuum system, is specifically related to a kind of modified condenser vacuum system.
Background technology
In thermal power plant, conventionally adopt water ring vacuum pump to extract incoagulable gas in condenser, to guarantee the vacuum of condenser.The working solution of water ring vacuum pump is water, and its design temperature is generally 15 ℃, if the temperature of working solution is higher than its design load, can make working solution vaporize, thereby make vavuum pump generation cavitation, cause the decrease in efficiency of vavuum pump, thereby cause the vacuum of condenser to decline, and then generating efficiency is declined.
In actual motion, because acting and water vapour release gasification latent heat can cause working solution temperature constantly to raise.Therefore, for guaranteeing the operating efficiency of water ring vacuum pump, working solution need to be undertaken by recirculated cooling water cooling conventionally, but circulating cooling coolant-temperature gage is subject to the impact in season, along with the rising of circulating cooling coolant-temperature gage, often can not be cooled to design load by the temperature of working solution summer.
Application number " 201310288118.4 " name is called the patent of invention of " condenser steam jet vacuum system ", announce a kind of condenser vacuum that makes and maintained all the time high-caliber modified condenser vacuum system, to adopt steam jet ejector to control separately single condenser, or controlling the condenser that several are in parallel, the port of export of condenser is connected on water ring vacuum pump, on the export pipeline of water ring vacuum pump, connects steam-water separator, working solution heat exchanger with its formation vacuum system.Although result of use is better, in the time need to completing fairly large operating mode, need the corresponding many group systems that formed by above-mentioned all parts that add, production and use cost are higher.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, improvement cost is low, can make condenser vacuum still can maintain all the time high-caliber modified condenser vacuum system when extensive operating mode.
A kind of modified condenser vacuum system, comprise the female pipe of the condenser joining with condenser, on the female pipe of described condenser, be connected with steam jet ejector and condenser, described steam jet ejector be take steam as dynamic medium, by power jet, produce supersonic jet, in head chamber, cause vacuum, extract the vapour gas mixture in condenser, water vapour in power steam and the condenser pumped gas device that is condensed is condensed into water, be recovered in hot well, the incondensable gas in system enters vacuum pump system by the female pipe of condenser again and carries out application of vacuum; Described vacuum system is at least three groups, being parallel way is connected on the female pipe of condenser, described vacuum pump system consists of water ring vacuum pump, steam-water separator and working solution heat exchanger, the female pipe of described condenser is connected to the suction end place of water ring vacuum pump, the outlet side of described water ring vacuum pump is connected on steam-water separator, and the internal work system of described water ring vacuum pump and working solution heat exchanger form loop.
Further improvement as technique scheme:
The entrance point of the power steam pipeline at the female pipe of described condenser and steam jet ejector place is separately installed with manual isolating valve and pneumatic control valve.
The utility model applied range, what applicable to current power plant, adopt take the pumped vacuum systems that multi-group vacuum pump is main body, also there is in addition advantage simple in structure, improvement cost is low, can make condenser vacuum still can maintain all the time high-level state when extensive operating mode.
