Technical field
The present invention relates to a kind of plain boiled water defoaming devices of paper machine system wet end abjection, more particularly, to a kind of efficient white
Eaves gutter slot defoaming device.
Background technique
In paper for daily use paper manufacturing streams, short cyclic design generally uses plain boiled water chute device, main function be by
The Free water of wet end removing is collected into plain boiled water chute, and the plain boiled water in chute is directly used as starching dilution plain boiled water, and so circulation can
Reduce water consume.But because paper for daily use paper machine speed is higher, using the type speed of crescent former up to 2200 ms/min,
Quickly, the impact of plain boiled water cyclic process will necessarily generate a large amount of bubbles to plain boiled water circulation rate under high speed in plain boiled water chute.Together
The use of Shi Yinwei chemicals especially wet strength agent and the fluctuation of pH, also will increase the yield of bubble.This in plain boiled water chute
The presence of a little bubbles, will affect the molding of page, can also have an impact to the fluctuation of Substance, bring to the stability of system
Fluctuation.
Most common existing plain boiled water chute debubbling method is exactly to add defoaming agent, and defoaming agent generally has degasification and defoaming
Effect, can largely eliminate inside plain boiled water in plain boiled water chute and the bubble on surface, if but plain boiled water blibbing it is excessive, largely
Ground addition defoaming agent can bring variation to the property of plain boiled water, because defoaming agent has oil components, in paper for daily use production process, greatly
Phenomena such as amount uses defoaming agent that can slurry be easily peeled off on Flying Dutchman, causes page unstable or monochromatic light, increases tune
The difficulty for saving drying cylinder coating, reduces the stability of coating.
203569379 U of Chinese patent CN discloses a kind of efficient white wate tray blowdown apparatus, including web part of paper machine, white
Sink, weight slag sewage pipe, weight stock pump, the web part of paper machine are connected to back flow water pump, and the heavy slag sewage pipe, weight stock pump are set respectively
It sets in plain boiled water trench bottom, further includes blowoff basin under adjustable baffle plate, light slag sewage pipe and machine, the adjustable baffle plate setting exists
In back flow water pump, back flow water pump is divided into blowdown area and overflow area, the heavy slag sewage pipe, weight stock pump are located at blowdown area bottom, institute
Blowoff basin is connected to overflow area by pipeline under the machine stated, and light slag sewage pipe is arranged on the pipeline.Above-mentioned apparatus is mainly used
It is but poor for the bubble treatment effect in back flow water pump in the contaminant removal effectiveness for improving back flow water pump.
Summary of the invention
Simple, reduction that it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of structures
Add spraying stability, efficient plain boiled water chute defoaming device outside defoaming agent dosage, raising drying cylinder.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of efficient plain boiled water chute defoaming device, including white water chest under web part of paper machine, plain boiled water chute and machine, the paper
Machine wet end is connected with plain boiled water chute water inlet end, and white water chest is connected by water-supply-pipe with plain boiled water chute water outlet under the machine
Logical, the plain boiled water chute upper end is provided with defoaming agent addition pipeline and defoaming spray pipeline.
The nozzle of the plain boiled water chute water surface is provided perpendicular on the defoaming spray pipeline.
The nozzle is fan nozzle, and the nozzle is laid along the length direction and/or width direction of plain boiled water chute.
The downstream of defoaming agent addition pipeline is arranged in the water (flow) direction along plain boiled water chute, the nozzle.
Controllable register is equipped in the plain boiled water chute, plain boiled water chute is divided into blowdown area and overflow by the controllable register
Area, the defoaming agent addition pipeline and defoaming spray pipeline are arranged above blowdown area, and the water-supply-pipe connection is being overflow
It flows in area.
The blowdown area bottom is connected with weight slag sewage pipe and fan pump.
Light slag sewage pipe is connected on the water-supply-pipe.
The light slag sewage pipe is equipped with regulating valve.
Defoaming spray pipeline is made of stainless steel pipeline and fan nozzle, mainly using the mode of spray, allows water dispersion
Ground is sprayed above the bubble on plain boiled water surface, eliminates bubble.Setting defoaming spray pipeline, makes itself and plain boiled water on plain boiled water chute
The direction of flowing is vertical, and water is continuously sprayed onto plain boiled water surface, bubble is eliminated.Its installation site is plain boiled water chute defoaming agent
After addition, before dilution sizing material, can also continuous series 2-3 device is installed, to remove more foams, nozzle is installed
For quantity depending on plain boiled water chute size, specific installation site can the practical prospecting in scene.The mode of spray can be sprayed continuously
Spray can be interrupted.
Compared with prior art, the present invention has the following advantages and beneficial effects:
(1) it is provided with defoaming agent addition pipeline and defoaming spray pipeline simultaneously, and is set at defoaming agent addition pipeline rear
Defoaming spray pipeline is set, the bubble on plain boiled water surface in plain boiled water chute can be eliminated on the basis of not increasing defoaming agent, is saved
The cost of chemicals；
(2) because using system plain boiled water, while saving chemicals cost, the stabilization for adding spraying outside drying cylinder is improved
Property；
(3) adaptability of the device and strong, can continuously spray, can also discontinuously spray, can 1- if plain boiled water bubble is excessive
3 root devices are online simultaneously to open, and reaches most strong defoaming effect；If foam is less, defoaming agent is completely removed, then can not be added
Or a small amount of addition.
