Lai te in a paper machine to separate water from the air stream Anordning i en pappersmaskin for att separera vatten från en luftstrøm

The invention relates to a water separator in a paper machine, the function of which is to separate water from 10 aqueous air when aqueous air is introduced from a vacuum object, e.g. a suction cylinder or suction box. for directing air from the water separator to the vacuum pump and for discharging at least one pipe connection outlet from the water separator connection 15 at the bottom of the water separator, and that the water separator comprises an air conduit to the vacuum pump

The foot treatment of the air stream from the suction rollers or suction box of the paper machine to separate the water 20 from the air stream has taken place in a water separator. However, the known water separators have not allowed the best possible use of the space and the best possible water resolution. In particular, the piping above the separators has taken up a lot of space and has resulted in the separator not being able to be placed high enough, which in turn would allow the lockwater well to be lowered. The curved pipe sections 25 above have also led to an expensive separator structure.

This application discloses a new device for separating water from an air stream.

The main aspect of the invention is fasted by the realization that the air for the vacuum pump is adapted to be led out of the separator body through the side or bottom surface of the separator. In the solution, the end of the pipe going to the vacuum pump is arranged to open at the top of the separator space, preferably so that the inlet opening A of the pipe is located horizontally 2 with respect to the central axis X of the separator. Surface A is also located above the inlet of the pipe coming from the hollow object with the water separator in its operating position. In the solution according to the invention, the separator covers the sloping bottom surface, whereby the separated water is transferred by gravity to the lowest point of the bottom and to the drainage pipe located there. 5

The water separator according to the invention is mainly characterized in that the water separator stores an air pipe connection to the vacuum pump, the end of which is adapted to open upwards in the upper part of the separator separation space and

The invention will now be described with reference to some preferred embodiments of the invention shown in the figures of the accompanying drawings, to which, however, the invention is not intended to be exclusively limited.

Figure 1 shows a water separator solution according to the prior art. Based on the figure, the problems occurring in the separator structure and caused by the separator structure are illustrated.

Figure 2A shows a first preferred embodiment of a water separator solution according to the invention.

Figure 2B is a section I-I of Figure 2A.

Figure 3A shows another preferred embodiment of a water separator according to the invention.

Fig. 3B shows a section Π-Π of Fig. 3A.

Figure 1 shows a water separator according to the prior art. As shown in the figure, an air flow is supplied to the separator via the pipe connection Tj and the air is sucked to the vacuum pump further via the pipe connection T2 connected to the top of the separator. The separated water is discharged 91175 3 through drainage connection T3 at the bottom of the separator. As shown in FIG. In addition, the water separator must be located below the support beam structures E to allow pipe outlets to the vacuum pump P. In this case, the water separator has to be placed down, in which case the lock water well also has to be lowered.

Figure 2A shows a separator solution according to the invention. In the structure according to the invention, the separator 10 can be arranged as close as possible to the roof structure K in the vicinity of the beam E. This is made possible in that the supply of air to the vacuum pump P is adapted to take place either from the side surface 11a of the separator body 11 or through its bottom surface 11b.

As shown in Fig. 2A, a separator 10 is provided with an air inlet pipe 12, through which aqueous air is led from a vacuum object, e.g. from a suction roll, as shown in the figure. The inlet 12a opens into the internal space 13 of the body 11 and the air inlet 12a is located below the inlet 14a of the pipe 14 leading to the vacuum pump in the drive-20 of the device. The end 14a of the pipe 14 to the vacuum pump is arranged to open upwards in the upper part of the separator separator strip 13. As shown in the figure, the inlet opening 14a of the air transfer to the vacuum pump is arranged horizontally with respect to the central axis X of the separator and the pipe connection 14 to the vacuum pump is arranged to be passed through the side surface 1a of the body II. The drain water connection 15 is adapted to open from the horizontal plane 25 of the body 11 inclined from the bottom surface 1 lb at the lowest point of the bottom surface 1 lb, whereby all water can be transferred by gravity from the inclined bottom lib of the water separator 10 shown by arrows 1 ^. The figure also shows the application / suction roller of the water separator. The application can be any other paper machine device to which aqueous air is removed.

Figure 2B is a section I-I of Figure 2A. As shown in the figure, it can be seen that the cross-sectional shape of the body 11 of the water separator 10 is a circle. The pipe connection 14 is supported on the body 11 by a support 16.

Fig. 3A shows an embodiment of the invention in which air is sucked from a hollow object so that the supply air connection 13 is passed through the upper surface 11c of the body 11 of the separator 10. The inlet 13a is located in the space 13 inside the body 11 of the water separator 10 below the outlet 14a of the pipe connection 14 leading to the vacuum pump. The water is removed from the water separator through a drainage connection 15 on the basis of 1 lb. In the embodiment-10a of the figure, the connection 14 leading to the vacuum pump is introduced through the bottom surface 11b of the body 11 of the water separator 10 to the vacuum pump P. The end 14a of the pipe 14 to the vacuum pump is arranged to open upwards at the top of the separator space 13.

Fig. 3B shows a section Π-Π of Fig. 3A. The pipe connections 13 and 14 are supported inside the water separator 15 by a connecting part 17.
