Description
Technical field
This utility model relates to a kind of pumped vacuum systems, sets up high back pressure particularly to a kind of Direct Air-Cooled thermal power plant unit and coagulates
Vapour device pumped vacuum systems.
Background technology
The heat recovery technology of Direct Air-cooled Unit has become an important energy-conserving and emission-cutting technology, for Winter heat supply
Direct Air-cooled Unit is particularly important.Direct Air-cooled Unit have run back pressure of a relatively high and be easy to run control feature, mesh
Before, the mode of high back pressure coagulator is set up in the current more employing of waste heat recovery, not only increases the heat capacity of unit, Er Qieti
The high economy of thermal power plant unit heat supply running.After exhaust steam entrance high back pressure condenser condensation heat release, incoagulable gas is by unit
Vacuum pump is extracted out.Owing to during heat supply running, unit back pressuce adjusts higher, generally higher than 35kPa, evacuate temperature and be up to 70 DEG C
Left and right, and high back pressure condenser rate of air sucked in required is big, long-time suction high temperature vapour gas mixture can cause vacuum pump fluctuation of service and
High back pressure condenser vacuum-pumping pipeline is vibrated, and has had influence on exerting oneself of vacuum pump.
Summary of the invention
This utility model provides a kind of Direct Air-Cooled thermal power plant unit pumped vacuum systems that can make vacuum pump stable operation, solves
Determine and set up vacuum-pumping pipeline vibration and the technical problem of vacuum pump fluctuation of service after high back pressure condenser.
This utility model is to solve above technical problem by the following technical programs:
A kind of Direct Air-Cooled thermal power plant unit pumped vacuum systems that can make vacuum pump stable operation, including air cooling system and main frame
Vacuum pump, the vacuum-pumping pipeline between air cooling system and main frame vacuum pump is provided with air cooling system control valve, high back pressure
Condenser is linked together with main frame vacuum pump by high back pressure condenser vacuum-pumping pipeline, at high back pressure condenser vacuum-pumping tube
It is respectively arranged with direct-contact desuperheater and high back pressure condenser evacuation control valve on road, direct-contact desuperheater is provided with desuperheat
Water input conduit and shower nozzle.
Direct-contact desuperheater is provided with U-shaped curved hydrophobic pipeline, the other end with U-shaped curved hydrophobic pipeline and main frame
Steam exhaust device links together.
This utility model by high back pressure condenser extract out high temperature vapour gas mixture carry out desuperheat and decrement treatment,
Improve the working environment of vacuum pump so that it is working stability.
