Description
Technical field
The present invention relates to pulp and paper technology field, more particularly to a kind of steam box for preventing condensed water from dripping and method.
Background technology
In Dryer Section of Paper Machine and calender, steam is sprayed along paper banner, steam is condensed in paper, discharges latent heat,
So as to improve the drying capacity in drying cylinder portion, the uniformity of paper web moisture profile content can be adjusted, paper after press polish can be improved
The coating performance of printing performance and coating paper, and the banner uniformity of printing performance, therefore, steam box is widely used in various
On the paper machine of high-grade paper, particularly on speciality paper machine, such as decorating base paper.
The steam gushed out in steam box is very important away from water droplet, and the water droplet for otherwise ejecting can be produced on paper
Raw paper defects.On the other hand, for the steam box on drying section and calender, the steam purpose of injection is to adjust paper moisture content to contain
Amount, therefore the moisture in steam is that comparison is high, generally using saturated vapor, saturated vapor runs into the slightly lower object of temperature
When will condense to form water droplet.
In the production process of factory, due to the impact of the factors such as maintenance or contingency, paper machine is not continuous operation
, when starting shooting again after shutdown, the temperature of steam box is already clearly below the temperature of saturated vapor, so runs at the beginning, and steam is cold
The condensed water formed after solidifying will spray in first wave steam from nozzle.Additionally due to be not in steam it is absolutely dry,
Even if during continuous operation, it is also possible to have water droplet to enter in steam box, this be accomplished by steam box have it is good
Prevent water droplet from falling the method on paper and the device supporting with method.
Traditional solution is that the position lower than nozzle is provided with a series of condensate water extraction device.
The solution adopted in the patent application of Application No. US3795578 and US3726757 is using corrugated
Base plate, nozzle is located at corrugated peak, and trough is used for draining, but this method is produced cold when not solving just to start shooting
The problem of solidifying water, even if the condensed water that other positions produce is discharged by trough, but can still produce condensed water in nozzle, this
Outer hogbacked floor manufacture is cumbersome.Wherein, US3574338 installs injection standpipe on the base plate of steam box, so that steaming
Vapour entrance is higher than base plate, but the top of standpipe is plane, and the condensed water that top surface is produced can be flowed in nozzle, while this side
Method does not also solve the problems, such as condensed water produced when just starting shooting, and the standpipe for cooling down provides machine for the formation of condensed water
Meeting.
The patent application of Application No. US5211813 provides another kind of solution, and steam box includes multiple vaporiums,
In addition to Preheated steam room, from the next steam of house steward through multiple vaporiums, filter out be sprayed onto again on paper after condensed water layer by layer, from
And making the steam of ejected towards paper not contain condensed water, this method is very effective, but equipment is extremely complex, the cost of manufacture and maintenance
It is high.

Steam, steam is entered after pre- thermofin, and steam casing and steam playpipe are preheated；After the completion of preheating, preheating is adjusted
Management and control valve, reduces the steam flow in pre- hot leg pipe, meanwhile, main steam range is steamed by each steam branch pipe to the conveying of steam casing
Vapour, steam is entered after steam casing, and by steam playpipe paper is ejected into.Specially：
Main steam range control valve is first shut off, is opened on pre- hot leg pipe control valve and the opposing steam flow pipe on pre- hot leg pipe
Recycle control valve, for whole steam casing is preheated, prevents steam from producing condensed water when entering in steam casing；Work as steam
When temperature in casing reaches the temperature of steam, preheating is completed, and steam box starts normal work, now suitably turns down pre- hot leg pipe
Steam flow, while turning down recycle control valve.
Main steam range control valve is opened, steam is entered in corresponding vaporium by every group of steam branch pipe, steam branch pipe
It is to enter in vaporium from side, that is to say, that the direction for entering vapour is vertical with the direction of steam ejected towards paper, so on the one hand
The adverse effect of steam impringement paper generation is avoided, the condensed water that on the other hand preventing may carry in steam is sprayed onto paper
On；Steam is sprayed onto on paper again after entering in vaporium by steam playpipe, because Preheated steam enters to steam playpipe
Go preheating, therefore steam will not produce condensed water when by playpipe, the steam inlet of simultaneous steam injection pipe outer wall is in
Taper, spraying the condensed water that formed in pipe outer wall in steam will not flow in steam playpipe, and can be directly entered the along outer wall
On one base plate, then drained by condensate pipe；In addition the steam inlet of steam playpipe 10mm higher than the first base plate or so, from
And the condensed water that can avoid being formed in steam box is entered in steam playpipe.
Steam branch pipe is laterally uniform along paper machine, corresponding with the vaporium of steam casing, each vaporium and two
Root steam branch pipe is communicated, and steam branch pipe control valve is provided with the steam branch pipe of vaporium side, another positioned at vaporium
Valve is controlled without steam branch pipe on the steam branch pipe of side, because steam branch pipe one (controls the steam of valve with steam branch pipe
Pipe) caliber more than steam branch pipe two (i.e. without steam branch pipe control valve steam branch pipe) caliber, such that it is able to pass through
Individually control steam branch pipe one to control the steam flow of correspondence vaporium, valve consumption is reduced, while having reached regulation paper
Open the purpose of banner water content.
As described above, just can preferably realize the present invention, above-described embodiment is only presently preferred embodiments of the present invention, is not used
To limit the practical range of the present invention；I.e. all impartial changes made according to present invention and modification, all will for right of the present invention
Scope required for protection is asked to be covered.
