Description
Technical field
The utility model relates to thermoelectricity field, particularly relates to a kind of device of eliminating the vibrations of boiler drain water piping.
Background technology
Current domestic station boiler is the cold end corrosion of avoiding heated surface at the end of boiler, generally adopts the mode of steam air heater preheating wind-warm syndrome to solve.Steam air heater is arranged in air preheater import air channel, utilizes drawing gas of steam turbine to carry out preheating to improve the tube wall temperature of heated surface at the end of boiler to Cryogenic air, prevents cold end corrosion and stifled grey phenomenon.In actual motion, the variation of unit load, environment temperature, steam parameter etc. can cause that steam air heater drain temperature changes, steam air heater drain temperature is sometimes higher, high temperature hydrophobic after drainage pump throttling pressure decreased, hydrophobic pressure is lower than hydrophobic saturation pressure, and hydrophobic vaporization, produces unsettled two phase flow, the hydrophobic water hammer that produces in pipeline, causes pipe vibration violent and unstable.Thereby cause pipe welding seam frequently to ftracture, system operational percentage is low, reliability extreme difference, hydrophobic can not get for a long time of steam air heater reclaimed, and condensate water waste is serious.
Utility model content
An object of the present utility model is that a kind of device of eliminating the vibrations of boiler drain water piping will be provided.
Especially, the utility model provides a kind of device of eliminating the vibrations of boiler drain water piping, comprise: steam air heater drain tank, drainage pump and deaerator storage tank, described steam air heater drain tank is connected by the first pipeline with drainage pump, described drainage pump is connected by second pipe with described deaerator storage tank, on described second pipe, control valve is installed; Wherein
The link of described second pipe and described deaerator storage tank is provided with to be stressed controls at least one spring nozzle of folding.
Further, the link of described second pipe and described deaerator storage tank stretches in described deaerator storage tank, and described spring nozzle is arranged on the termination that this second pipe stretches into described deaerator storage tank.
Further, described at least one spring nozzle is two and is spaced along the axial line of described second pipe.
Further, described spring nozzle is positioned at the top of inner hydrophobic of described deaerator storage tank and it sprays direction towards the described hydrophobic water surface.
Further, the opening pressure of described spring nozzle is lower than the hydrophobic pressure in second pipe between described control valve and described drainage pump.
On drain water piping of the present utility model, due to spring nozzle being installed, therefore make the inner pressure of drain water piping (second pipe) higher than hydrophobic pressure for vaporization, prevented hydrophobic vaporization, thereby eliminated the internal cause of drain water piping vibrations.Ensure hydrophobic normal discharge, avoided the loss of working medium and heat.
According to the detailed description to the utility model specific embodiment by reference to the accompanying drawings below, those skilled in the art will understand above-mentioned and other objects, advantage and feature of the present utility model more.
Brief description of the drawings
Hereinafter describe specific embodiments more of the present utility model in detail in exemplary and nonrestrictive mode with reference to the accompanying drawings.In accompanying drawing, identical Reference numeral has indicated same or similar parts or part.It should be appreciated by those skilled in the art that these accompanying drawings may not draw in proportion.In accompanying drawing:
Fig. 1 is according to the schematic diagram of the device of the elimination boiler drain water piping vibrations of an embodiment of the utility model.
Detailed description of the invention
Fig. 1 is according to the schematic diagram of the device of the elimination boiler drain water piping vibrations of an embodiment of the utility model.This device can comprise steam air heater drain tank 10, drainage pump 20 and deaerator storage tank 30 in general manner.This steam air heater drain tank 10 can be connected by the first pipeline 40 with drainage pump 20, and drainage pump 20 can be connected by second pipe 50 with deaerator storage tank 30, and control valve 51 is installed on second pipe 50.Wherein on the link of second pipe 50 and deaerator storage tank 30, can installing is stressed controls at least one spring nozzle 52 of folding.The utility model directly discharges hydrophobic mode by second pipe 50 to deaerator storage tank 30 and makes into discharge by spring nozzle 52, the hydrophobic pressure that makes to be positioned at the second pipe 50 after control valve 51 only, in the time reaching spring nozzle 52 and open required pressure, can be sprayed by spring nozzle 52 places.Improve the hydrophobic pressure in second pipe 50 by spring nozzle 52, can make the hydrophobic pressure of control valve 51 front and back tend to balance.Two phase flow phenomenon from differential water pressures to deaerator storage tank 30 internal drainages that avoided second pipe 50 directly to occur due to.Thereby can reach the object of eliminating drain water piping vibrations.
As shown in Figure 1, in an embodiment of the present utility model, second pipe 50 and the link of deaerator storage tank 30 can be stretched in deaerator storage tank 30, and spring nozzle 52 can be arranged on this second pipe 50 and stretches on the termination of deaerator storage tank 30.Avoid the hydrophobic equipment that affects other, be also beneficial to hydrophobic recovery simultaneously.
In an embodiment of the present utility model, spring nozzle 52 is preferably two and be spaced along the axial line of second pipe 50.Two spring nozzles 52 can be shared the pressure in second pipe 50, can also reduce single spring nozzle 52 and spray hydrophobic pressure.
In an embodiment of the present utility model, spring nozzle 52 can be arranged on to the top of inner hydrophobic of deaerator storage tank 30 and it sprays direction towards the hydrophobic water surface.With hydrophobic other parts in its deaerator storage tank 30 being caused damage of avoiding that spring nozzle 52 sprays.
In an embodiment of the present utility model, the opening pressure of this spring nozzle 52 can be lower than the hydrophobic pressure in second pipe 50 between control valve 51 and drainage pump 20.The opening pressure size of concrete spring nozzle 52 can deduct deaerator storage tank 30 minimum operating pressures as standard taking the saturation pressure under high temperature drain temperature correspondence.
In an embodiment of the present utility model, deaerator storage tank and drainage pump need to be considered drop and/or the opening pressure impact of distance on spring nozzle between the two.In the utility model, top and both drops that deaerator storage tank 30 can be arranged on to drainage pump 20 are greater than 24 meters.Therefore in the time selecting spring nozzle 52, except considering the hydrophobic pressure of control valve 51 front and back on second pipe 50, also need the unlifting pressure of considering that deaerator storage tank 30 and drainage pump 20 both drops form.
So far, those skilled in the art will recognize that, illustrate and described of the present utility model multiple exemplary embodiment although detailed herein, but, in the situation that not departing from the utility model spirit and scope, still can directly determine or derive many other modification or the amendment that meet the utility model principle according to the disclosed content of the utility model.Therefore, scope of the present utility model should be understood and regard as and cover all these other modification or amendments.
