A silencer is arranged on the exhaust pipe and comprises a shell, the shell is provided with an exhaust outlet, an exhaust barrel is disposed in the shell and provided with exhaust holes, the exhaust barrel is communicated with the exhaust pipe and a connecting pipe, and the connecting pipe is hermetically connected with the shell and communicated with the exhaust pipe.
Description
Technical field
The utility model relates to a kind of Turbo-generator Set master's air ejector, belongs to field of mechanical technique.
Background technique
In condensing steam turbine generator group or sucking condensing type Turbo-generator Set, be typically equipped with startup air ejector and main air ejector.The effect one of the two is by starting air ejector and main air ejector the air in the vapour condenser to be extracted out to set up vacuum when unit starting or shutdown; The 2nd, normally in service, the effect of main air ejector is that the small leak of a small amount of incondensable gas that will contain in the turbine discharge and vapour condenser itself and connected system thereof is extracted out, to keep condenser vacuum.
As shown in Figure 1 and Figure 2, main air ejector generally is made up of two stream-jet ejectors and two coolers, is called the secondary air ejector, promptly is made up of stream-jet ejector 2, stream-jet ejector 3 and cooler 11, cooler 12; By initial steam pipe or the suitable extraction steam pipe of pressure, steam is caused stream-jet ejector 2, after entering, steam begins expand to quicken and enter in the mixing chamber 15, in mixing chamber 15, formed the vacuum of height, thereby vapour, gas mixture in the vapour condenser 5 have been taken out, in mixing chamber 15 Yu after the blending of high speed steam flow, entered in the diffuser pipe.Vapour, gas mixture flow velocity in diffuser pipe reduces, and pressure raises gradually, when pressure rises to a certain numerical value of condenser pressure and atmospheric pressure centre, just enters in the cooler 11 of first order air ejector.Steam overwhelming majority in the cooler 11 of first order air ejector be cooled condense into hydrophobic, do not condense into hydrophobic vapour, gas mixture enters second-stage ejector through connecting tube, be compressed to the pressure higher slightly by the diffuser pipe of second-stage ejector than atmospheric pressure, enter partial cooler 12 again, most steam are cooled and condense into hydrophobicly in cooler 12, and remaining a small amount of vapour, gas mixture enter in the atmosphere by outlet pipe 13.
In actual use, the exhaust meeting of main air ejector produces very big noise.Both influenced execute-in-place workman's physical and mental health, also disturbed the inspection of operations staff on-the-spot other unit exception sound.
The model utility content
Problem to be solved in the utility model is at above problem, a kind of Turbo-generator Set master's air ejector is provided, the huge noise that produces in the time of can reducing main air ejector exhaust, make the execute-in-place workman that a good working environment can be arranged, also help the inspection of operations staff on-the-spot other unit exception sound.
For overcoming the above problems, the technological scheme that the utility model adopted is: Turbo-generator Set master's air ejector, comprise stream-jet ejector, cooler and outlet pipe, and outlet pipe is provided with baffler.
As further improvement in the technical proposal:
Described baffler comprises shell, and shell is provided with relief opening, is provided with exhaust pipe in the shell, and exhaust pipe is provided with exhaust port, and exhaust pipe is communicated with outlet pipe.
Described exhaust pipe is communicated with connecting tube, and connecting tube is connected with body seal and is communicated with outlet pipe.
The utility model adopts technique scheme, have the following advantages: after vapour, gas mixture enter baffler by outlet pipe and connecting tube, vapour, gas mixture at first enter in the exhaust pipe, enter cavity between shell and the exhaust pipe by exhaust port then, slowed down the velocity of discharge of gas, the noise that greatly reduce vapour, produces when gas mixture is discharged; Simultaneously, owing to vapour, gas mixture flow velocity in baffler reduces and waiting time prolongation, most of vapour, gas mixture are condensed into water, can recycle and reuse.Like this, not only optimize working environment, and reclaimed water of condensation, saved water resources.
The utility model is described in further detail below in conjunction with drawings and Examples.
