Abstract

The invention relates to a drying cylinder condensate water draining device. The drying cylinder condensate water draining device comprises a draining pipe installed in a drying cylinder, one end of the draining pipe extends out of the drying cylinder, multiple separators are installed on the draining pipe, an inlet of each separator is connected with a winnowing pan, and an outlet of each separator is communicated with the draining pipe. By means of the winnowing pans, condensate water in the drying cylinder carries part of steam to rush into the separators, the condensate water and the steam are separated through the separators, the steam returns into the drying cylinder, only the condensate water enters the draining pipe under the action of gravity, in this way, the stable flowing state in the draining pipe is kept, and the condensate water can be conveniently drained in time. The condensate water draining device is particularly suitable for draining condensate water in medium-and-high-speed paper making machines.

Description

Drying cylinder condensate water extraction device

[technical field]

The present invention relates to condensed water and discharge field, be specifically related to a kind of drying cylinder condensate water extraction device.

[background technology]

Currently with water vapour phase transformation heat release in rotor, cylinder outer surface is very universal to the device of heating material. There is condensed water and discharge difficulty in this heater, in order to overcome this difficulty, people have carried out various effort, particularly in pulping and paper-making industry, in order to improve the drying efficiency of paper machine, being necessary for discharging the condensed water in drying cylinder in time, people take to arrange the structures such as helicla flute, tabulator bars, rotation siphon in drying cylinder, but effect still can not meet industrial requirement, its reason is that above-mentioned measure is all without improving the state of unstable stream-liquid two-phase flow in drying cylinder drain pipe.

[summary of the invention]

It is an object of the invention to overcome problems of the prior art, it is provided that a kind of drying cylinder condensate water extraction device, it is possible to make to maintain in drain pipe steady flow condition, it is simple to discharged by condensed water in time.

In order to achieve the above object, the present invention adopts the following technical scheme that

Including the drain pipe being arranged in drying cylinder and one end extends to outside drying cylinder, drain pipe is provided with several separators; The import of each separator is all connected with winnowing pan, and outlet is all connected with drain pipe.

Further, drying cylinder includes cylinder, and is arranged on left end cap and the right end cap at cylinder two ends; The centrally disposed blind hole of left end cap, the centrally disposed through hole of right end cap; The left end support of drain pipe blind hole place on left end cap, right-hand member is through the through hole on right end cap, and seals assembling between drain pipe and right end cap.

Further, the import of each separator connects winnowing pan each through collector pipe.

Further, the outlet of each separator connects drain valve, drain valve communicated drainage pipe each through aqueduct.

Further, the outlet of separator 0.3m higher than the import of drain valve.

Further, separator all adopts steam-water separator.

Further, the drain pipe extended to outside drying cylinder is fixed in frame.

Compared with prior art, the present invention has following useful technique effect:

In the present invention in drying cylinder condensed water because of the effect of winnowing pan, condensed water is taken and is wrapped up in some vapor and pour separator, by the effect condensed water of separator and vapor removal, steam returns in drying cylinder, it is only that condensed water enters drain pipe under gravity, thus maintain the steady flow condition in drain pipe, it is simple to discharged by condensed water in time. Present invention is particularly suitable for the discharge of condensed water in high speed paper machine.

Further, by the outlet of separator is arranged 0.3m higher than the import of drain valve in the present invention, it is ensured that condensed water discharges drop.

[detailed description of the invention]

Below in conjunction with accompanying drawing, the present invention is described in further details.

Referring to Fig. 1, drying cylinder of the present invention includes cylinder 2, and is arranged on left end cap 1 and the right end cap 10 at cylinder 2 two ends, the centrally disposed blind hole of left end cap 1, the centrally disposed through hole of right end cap 10; The left end of the drain pipe 8 of rigidity is radially fixed in the central blind hole of drying cylinder left end cap 1 by bearing, and the right-hand member of drain pipe 8, through the central through hole of drying cylinder right end cap 10 and after sealing assembling with this through hole, is fixed in frame 9; Rigidly fixing one group of separator 3 on drain pipe 8 between drying cylinder left end cap 1 and right end cap 10, separator 3 all adopts steam-water separator; The import of each separator 3 is rigidly connected respectively through collector pipe 5 and winnowing pan 4, and the outlet of each steam-water separator 3 is connected by the import of aqueduct 6 with a drain valve 7, and this drain valve 7 is fixed on drain pipe 8, and its outlet is connected with drain pipe 8.

It is not more than 10m according to condensation area in the drying cylinder cylinder 2 that each steam-water separator 3 is shared²Requirement determine the quantity of steam-water separator 3, and the outlet of steam-water separator 3 is higher than drain valve 7 import 0.3m, it is ensured that condensed water discharges drop.

The present invention utilizes the kinetic energy of condensation water ring in high speed paper machine dryer through the effect of separator 3 and drain valve 7, to make to maintain the state stablizing liquid phase stream in drying cylinder drain pipe 8, discharged in time by condensed water. The present invention is produced condensed water discharge after steam heating drying cylinder suitable in papermaking dry is processed, and especially rotor internal condensation water is discharged.

Main working process of the present invention and principle: in high speed paper machine dryer, condensation water ring is because of the effect of winnowing pan 4, condensed water is taken and is wrapped up in some vapor and pour separator 3, then condensed water and vapor removal, steam returns in drying cylinder, it is only that condensed water enters drain pipe 8 through drain valve 7 under gravity, thus maintain the steady flow condition in drain pipe 8, in time condensed water is discharged.
