Description
Technical field
A kind of pumped vacuum systems is the utility model is related to, it is high for Direct Air-Cooled using water ring vacuum pump more particularly to one kind
Back pressure thermal power plant unit carries out pumped vacuum systems.
Background technology
At present, Direct Air-cooled Unit is in the winter time during high back pressure heat supply running, since turbine discharge back pressure improves, row
Stripping temperature also and then raises, and causes the humid air temperature into water ring vacuum pump excessive, causes vacuum pump fluid temperature to improve,
The accidental conditions of vacuum pump are deviate from, decline water ring vacuum pump suction capactity, and produce substantial amounts of condensation water, influence vapour
The security and economy of turbine operation.In view of the above problems, the technological means that the prior art is mainly taken has two kinds：The first
The mode that high back pressure heating system independently adds pumped vacuum systems is adopted as, by increasing the quantity of vaccum-pumping equipment, to reach
Vacuum capability required by steam turbine normal operation, its main feature is that pumped vacuum systems operation is simple, easy to control, system operation
Effect is good, but due to add vacuum pump, it is necessary to it is supporting it is new construct the factory buildings and related facility, have cost of investment high, run power consumption
Measure the defects of big；Second is the mode for transforming original Water-ring vacuum pump fluid cooling system, by increasing original vacuum pump
Cooler heat exchange area, reduces working solution temperature, the original suction capactity of vacuum pump is kept, its main feature is that vacuum pump investment for trnasforming urban land
Small, operational effect is good after the system reform, but due to that can not be lowered into the water capacity of vacuum pump moist steam, there is vacuum pump to condense
The defects of water displacement is still big.
The content of the invention
The utility model provides a kind of Direct Air-Cooled pumped vacuum systems for reducing damp steam water capacity, solves existing
The uneconomical and high operating cost technical problem of transformation of the technology to former pumped vacuum systems.
The utility model is to solve above technical problem by the following technical programs：

Cooler, the Direct Air-Cooled on Direct Air-cooled Unit high back pressure condenser, which vacuumizes, to be connected with host and vacuumizes into vapour in main pipe
Pipeline, host is vacuumized to be connected together into the other end of vapor pipeline and the steam ports that enters of water ring vacuum pump cooler, is taken out in host
Vacuum, which enters, is provided with the first Motorized vacuum shut-off valve on vapor pipeline, host is connected with the venthole of water ring vacuum pump cooler
Steam outlet pipe road is vacuumized, the other end that host vacuumizes steam outlet pipe road is connected one with the steam ports that enters of host Water-ring vacuum pump group
Rise, vacuumized in host and the second Motorized vacuum shut-off valve is provided with steam outlet pipe road, the condensation water on water ring vacuum pump cooler
The other end of pipeline links together with the steam exhaust device of steam turbine on Direct Air-cooled Unit high back pressure condenser, in condensate pipe
Vacuum shut-off valve is provided with road.
The water supply line of water ring vacuum pump cooler is connected on Controlling Auxiliaries in Power Plants recirculated water water supply line, Water-ring vacuum
The outlet conduit of pump cooler is connected on Controlling Auxiliaries in Power Plants recirculated water water return pipeline.
The utility model is cooled down by being set between Direct Air-cooled Unit high back pressure condenser and host water ring vacuum pump
Device, that is, be lowered into water ring vacuum pump humid air temperature, ensures the normal work of water ring vacuum pump, but can recycle vacuumize it is solidifying
Bear water, power consumption is small during having reached pumped vacuum systems operation, the small purpose of condensation water drainage amount.
