Abstract
The invention relates to a papermaking dryer. A steam pipe and a supporting pipe are arranged in the dryer, and the dryer is provided with an inner barrel, which is provided with evenly distributed steam-spraying holes and fixed on the steam pipe and the supporting pipe. Since the inner barrel which is provided with the steam-spraying holes and fixed on the steam pipe and the supporting pipe is arranged in the dryer, steam enters the inner barrel via the steam pipe and flows out of the steam-spraying holes of the inner barrel at high speed to impact a circular condensed water layer on the inner wall of the dryer, so that the circular condensed water layer produces perturbation and turbulence, consequently, the heat transfer resistance of the circular condensed water layer is greatly decreased, the heat exchange efficiency is increased, however, the dynamic balance of the high-speed dryer cannot be affected; meanwhile, the structure is simple, and the parts are easy to machine.
Description
Technical field
The present invention relates to a kind of drying cylinder, relate in particular to a kind of high speed paper-making drying cylinder.
Background technology
It is lower that the paper machine ubiquity of the logical vapour system of the multistage of China's employing at present the drying section thermal efficiency, and steam consumption is higher.To high-speed paper machine, the condensed water that steam produces can form the stable water ring of being close to the drying cylinder internal face, and the condensed water turbulence is reduced, and it is very big that heat transmission resistance becomes, and heat transfer coefficient reduces.Promptly under the situation that does not adopt special interference, the thermal resistance of the condensation water ring that 1mm is thick in the drying cylinder approximates the thermal resistance of 15mm drying cylinder cast housing, and when condensed water circular layer thickness surpassed 2mm, thermal resistance significantly increased.
Someone proposes to add the flow-disturbing rod and itself and drying cylinder are together rotated at the drying cylinder inwall, because this structure can influence the dynamic balancing of high speed drying cylinder, therefore is inappropriate for the high speed drying cylinder.
Summary of the invention
The object of the present invention is to provide a kind of paper-making drying cylinder,, improve heat transfer efficiency, cut down the consumption of energy to reduce thermal resistance to generation disturbance of condensed water circular layer and turbulence.
The objective of the invention is to realize like this, a kind of paper-making drying cylinder, in establish steam pipe and stay pipe, said drying cylinder is provided with inner core, said inner core is provided with equally distributed steam fumarole and is fixed on said steam pipe and the stay pipe.
One end of said stay pipe is a blind end, and said stay pipe penetrates said steam pipe through its blind end front end and axially connects with it.
The two ends of said inner core are respectively equipped with flange and are fixed on said steam pipe and the stay pipe through said flange.
Be equipped with the shaft shoulder on said steam pipe and the stay pipe and cooperate the location respectively with said two flanges.
Also comprise siphon pipe, said siphon pipe is connected with said stay pipe through the slot of offering on the stay pipe tube wall.
The present invention has following beneficial effect:
1, the present invention is provided with the inner core of steam fumarole and is fixed on the steam pipe in drying cylinder; Steam gets into inner core from steam pipe; Steam fumarole from inner core sprays at a high speed again, directly impacts the condensed water circular layer on the drying cylinder inwall, makes it produce disturbance and turbulence; Reduce the heat transmission resistance of condensed water circular layer significantly, improved heat exchange efficiency.
2, because the steam fumarole that is provided with on the inner core is equally distributed, the steam that flows out at a high speed from steam fumarole impacts evenly the condensed water circular layer on the whole inwall of drying cylinder, and the temperature that helps on the whole outside wall surface of drying cylinder is even.
3, inner core of the present invention is fixedly mounted on steam pipe and the stay pipe, and drying cylinder is when rotating at a high speed, and inner core is non-rotary all the time, therefore can not influence the dynamic balancing of high speed drying cylinder.
4, siphon pipe of the present invention is arranged in the stay pipe, and stay pipe does not have and steam pipe UNICOM, and therefore, steam obviously reduces the heating of condensed water exclusion process, has further reduced the loss of heat, has improved the thermal efficiency.
5, the present invention is simple in structure, and handling ease is easy to realize.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation.
Among the figure, 1. steam pipe, 2. left flange, 3. inner core, 4. stay pipe, 5. right flange, 6. drying cylinder, 7. siphon pipe.
The specific embodiment
Embodiment, a kind of paper-making drying cylinder, in establish steam pipe 1, stay pipe 4 and siphon pipe 7, stay pipe 4 one ends are blind end and penetrate steam pipe 1 and axially connect with it that the steam in the steam pipe 1 capable of blocking gets in the stay pipe 4; Drying cylinder 6 is provided with inner core 3, and inner core 3 is fixed on steam pipe 1 and the stay pipe 4, and inner core 3 is provided with equally distributed steam fumarole.The two ends of inner core 3 are respectively equipped with left flange 2, right flange 5 and are separately fixed on steam pipe 1 and the stay pipe 4 through left flange 2 and right flange 5, and steam pipe 1 is provided with the shaft shoulder and cooperates the location with left flange 2, and stay pipe 4 is provided with the shaft shoulder and cooperates the location with right flange 5.Siphon pipe 7 is connected with stay pipe 4 through the slot of offering on stay pipe 4 tube walls.
During installation; Be sleeved on the right-hand end of inner core 3 on the steam pipe 1 earlier from drying cylinder 6; And make left flange 2 be positioned at the shaft shoulder place on the steam pipe 1; Advance the right side of steam pipe 1 to the blind end front end plug-in mounting of stay pipe 4, make steam pipe 1 and stay pipe 4 connect into an integral body, the steam in the blocking-up steam pipe 1 gets in the stay pipe 4; Make right flange 5 be positioned at the shaft shoulder place on the stay pipe 4 then, siphon pipe 7 is installed again.
During work; High pressure, high temperature vapor at first gets into the inner core 3 of drying cylinder 6 through a plurality of steam holes of offering on the steam pipe 1; Spray at a high speed from the steam fumarole that is distributed on the inner core 3, impact, make the highly stable condensed water circular layer of drying cylinder 6 inwalls produce disturbance and turbulence coagulating on the cold water circular layer on drying cylinder 6 inwalls; Heat transfer resistance significantly reduces, thereby has improved heat exchange efficiency.
