Evacuation mouth including steam turbine condenser (2) loops through the air inlet intercommunication of first isolating valve (3) and first tee bend (4) and steam ejector (6), and the steam inlet of steam ejector (6) communicates with the steam port of taking out of steam turbine (1), and the export of steam ejector (6) is passed through steam cooler (7) and is organized (17) intercommunication together with water ring vacuum pump, is provided with on water ring vacuum pump organizes (17) evacuation gas port (16). The utility model discloses guarantee the vacuum suction degree of condenser, avoided the water ring cavitation, improved water ring vacuum pump's operating stability and efficiency.
Description
Technical field
The evacuation system for steam condenser that this utility model relates to a kind of steam jet ejector and water ring vacuum pump combines, is that the mixture of condenser incoagulability gas and exhaust steam is first passed through steam jet ejector and steam condenser, the most again by the system of Water-ring vacuum pumped.
Background technology
At present, domestic present stage 300MW above generating set pumped vacuum systems many employings water ring vacuum pump system, because water ring vacuum pump has device integration height, the advantages such as stable and layout is convenient, but it is high to there is pumping limit pressure in water ring vacuum pump, easy cavitation, the shortcomings such as impeller life is short.When the suction ultimate value that the suction that generating set requires can reach higher than water ring vacuum pump, Unit Economic performance can be caused drastically to decline.Additionally, under the conditions of summer high temperature, uncooled steam enters in vacuum pump, water ring cavitation can be caused to occur, the internal mechanical performance of Water-ring vacuum pumping unit can decline, and has influence on the safe operation of equipment.
Summary of the invention
This utility model provides a kind of evacuation system for steam condenser, solves the easy cavitation of water ring vacuum pump summer high temperature and evacuation inhales hypodynamic technical problem.
This utility model is to solve above technical problem by the following technical programs:
nullA kind of evacuation system for steam condenser，Including steam turbine、Turbine condenser、Water-ring vacuum pump group and standby water-ring vacuum pump group，The vacuum orifice of turbine condenser is connected together by the left side mouth of the first isolating valve and first threeway，The right mouth of first threeway is connected together by the air intake of the second isolating valve with steam jet ejector，The steam inlet of steam jet ejector is connected together with the steam pumping mouth of steam turbine，The outlet of steam jet ejector connects with the vapour side entrance of steam condenser，The vapour side outlet of steam condenser is connected together by the end opening of the 3rd isolating valve and second threeway，Recirculated cooling water pipeline it is provided with in steam condenser，The middle port of second threeway is connected together by the middle port of the 4th isolating valve and first threeway，The end opening suitable for reading and the 3rd threeway of second threeway is connected together，The middle mouth of the 3rd threeway is connected together with water-ring vacuum pump group by the 5th isolating valve，Water-ring vacuum pump group is provided with emptying QI KOU，The suitable for reading of 3rd threeway is connected together with standby water-ring vacuum pump group by the 6th isolating valve，The delivery outlet of standby water-ring vacuum pump group is connected together with emptying QI KOU.

This utility model simple in construction, reliability is high, it is easy to safeguard, improve the incoagulability gas pressure of Water-ring vacuum pump inlet, it is ensured that the vacuum draw degree of condenser, it is to avoid water ring cavitation, improves operation stability and the efficiency of water ring vacuum pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail:
nullA kind of evacuation system for steam condenser，Including steam turbine 1、Turbine condenser 2、Water-ring vacuum pump group 17 and standby water-ring vacuum pump group 15，The vacuum orifice of turbine condenser 2 is connected together by the left side mouth of the first isolating valve 3 with first threeway 4，The right mouth of first threeway 4 is connected together by the air intake of the second isolating valve 5 with steam jet ejector 6，The steam inlet of steam jet ejector 6 is connected together with the steam pumping mouth of steam turbine 1，The outlet of steam jet ejector 6 connects with the vapour side entrance of steam condenser 7，The vapour side outlet of steam condenser 7 is connected together by the end opening of the 3rd isolating valve 10 with second threeway 11，Recirculated cooling water pipeline 8 it is provided with in steam condenser 7，The middle port of second threeway 11 is connected together by the middle port of the 4th isolating valve 12 with first threeway 4，The end opening suitable for reading and the 3rd threeway 13 of second threeway 11 is connected together，The middle mouth of the 3rd threeway 13 is connected together with water-ring vacuum pump group 17 by the 5th isolating valve 18，Water-ring vacuum pump group 17 is provided with emptying QI KOU 16，The suitable for reading of 3rd threeway 13 is connected together with standby water-ring vacuum pump group 15 by the 6th isolating valve 14，The delivery outlet of standby water-ring vacuum pump group 15 is connected together with emptying QI KOU 16.
Steam condenser 7 connects and has condenser hotwell 9.Steam is passed through steam jet ejector 6, supersonic jet is ejected from power jet, viscosity due to gas, high velocity air siphons away incoagulability gas and the mixture of exhaust steam in condenser, thus in evacuating feed channel, form vacuum, the mixture of incoagulability gas and exhaust steam enters steam condenser 7 after mixing with high velocity air, steam and condenser exhaust steam condense after being condensed water cooling and then return to condenser hotwell 9, incoagulability gas is discharged from cooler, at a higher pressure by water ring vacuum pump 17, then enter air.
