Abstract
A kind of boiler primary and secondary air steam air heater rotating device.When traditional steam air heater with spinfunction puts into operation, stops transport, steam inlet pipe repeatedly and hydrophobic pipe flange dismounting operation and temporary plugging measure need to be carried out, consumes human and material resources and working hour.A kind of boiler primary and secondary air steam air heater rotating device, composition include：Spun outer tube and rotating inner tube, the spun outer tube（7）One end connected with former steam air heater heater steam inlet pipe weldering, the other end installation rotating device ontology of the spun outer tube（6）, there is on the rotating device ontology filler chamber, filler is installed in the filler chamber, the rotating device ontology on gland with being bolted, the rotating inner tube（1）One end weldering be connected to the rear portion of former steam air heater intake system pipeline, other end installation gland（4）.The present utility model application is applied to boiler primary and secondary air steam air heater rotating device.
Description
Technical field：
The utility model is related to a kind of boiler primary and secondary air steam air heater rotating devices.
Background technology：
China's winter temperature is relatively low, and summer temperature is higher, temperature year difference it is larger.Temperature Change causes station boiler
It is certain to influence, such as low-temperature corrosion；To solve the above problems, station boiler generally installs steam air heater system additional, stop transport in steam air heater
When, in order to eliminate its resistance to system, station boiler generally use has a steam air heater of spinfunction, in normal position during use
It puts, stands and turn after stoppage in transit so that pressure difference minimizes before and after flue gas direction, reduces system resistance；And the warm wind with spinfunction
When device puts into operation, stops transport, due to the rotation of steam air heater, steam inlet pipe and hydrophobic pipe flange dismounting operation repeatedly need to be carried out and sealed temporarily
Stifled measure, consumes human and material resources and working hour.
Invention content：
The purpose of this utility model is to provide a kind of boiler primary and secondary air steam air heater rotating device.
Above-mentioned purpose is realized by following technical scheme：
A kind of boiler primary and secondary air steam air heater rotating device, composition include：Boiler primary and secondary air steam air heater rotating dress
It puts, composition includes：Spun outer tube and rotating inner tube, it is characterized in that：It is heated with former steam air heater one end of the spun outer tube
The weldering connection of device steam inlet pipe, the other end of the spun outer tube are installed rotating device ontology, are had on the rotating device ontology
There is filler chamber, filler is installed in the filler chamber, the rotating device ontology is described with being bolted on gland
One end weldering of rotating inner tube be connected to the rear portion of former steam air heater intake system pipeline, other end installation gland.
The boiler primary and secondary air steam air heater rotating device, the rotating device ontology are located in front of spun outer tube,
For the rotating inner tube and the spun outer tube to be enable to carry out relative rotation, with the spun outer tube using welding.
The boiler primary and secondary air steam air heater rotating device, the filler chamber, gland, filler, bolt and nut
Size is designed and is transformed into vapour and hydrophobic pipeline according to former steam air heater.
The boiler primary and secondary air steam air heater rotating device, the filler use graphite packing.
The beneficial effects of the utility model：
1. the steam air heater rotating device of the utility model, to be equipped with the primary and secondary air steam air heater with spinfunction
Station boiler in, replace former steam air heater steam inlet pipe and hydrophobic pipe flange, when putting into operation, stopping transport, avoid the steam air heater being repeated
Steam inlet pipe and hydrophobic pipe flange repeated disassembled and assembled operation and temporary plugging measure.
The steam air heater rotating device of the utility model saves human and material resources, when being the beginning of spring, the winter of entering and other climate changes
The safe and stable operation of station boiler provides reliable guarantee.
Description of the drawings：
Attached drawing 1 is the structure diagram of the utility model.
In figure：1-rotating inner tube；2-bolt；3-nut；4-gland；5-filler；6-rotating dress
Put ontology；7-spun outer tube.
Specific embodiment：
Embodiment 1：

Embodiment 2：
According to boiler primary and secondary air steam air heater rotating device described in embodiment 1, the rotating device ontology is located at rotation
Turn in front of outer tube, for the rotating inner tube and the spun outer tube to be enable to carry out relative rotation, adopted with the spun outer tube
With welding.
Embodiment 3：
According to boiler primary and secondary air steam air heater rotating device described in embodiment 1, the filler chamber, fills out gland
Material, bolt and nut size are designed and are transformed into vapour and hydrophobic pipeline according to former steam air heater.
Embodiment 4：
According to boiler primary and secondary air steam air heater rotating device described in embodiment 1, the filler uses graphite packing.
Embodiment 5：
Boiler primary and secondary air steam air heater rotating device according to one of embodiment 1 to 4, the rotating inner tube position
In former steam air heater intake system pipeline (or former steam air heater heater condensate pipe) rear, to connect the steam air heater rotating device
With former steam air heater intake system pipeline (or former steam air heater heater condensate pipe), using welding；Outer wall is smooth, to reduce opposite rotation
Produced frictional resistance when transhipment is dynamic, the spun outer tube is located at former steam air heater heater steam inlet pipe, and (or former steam air heater is hydrophobic
System pipeline) front, to connect the steam air heater rotating device and former steam air heater intake system pipeline, (or former steam air heater heats
