Description
Technical field
The invention belongs to pulping and paper-making fields, and in particular to a kind of copy paper system and copy paper method.
Background technology
With the continuous improvement of pulping and paper-making equipment, corresponding technological requirement is also higher and higher, especially in high speed paper
It is embodied clearly on machine, for example broken is gradually increased with the ratio of copying；White water system utilization rate is gradually increased；Slurry temperature liter
It is high.On high-speed paper machine, traditional non oxidizing bactericide such as Kathon CG, glutaraldehyde, organic bromine, s-triazine, dodecyl
Benzyl ammonium chloride etc. is very undesirable to the rotten slurry control of copy paper system under low dosage adding conditional, can frequently result in disconnected paper,
Some non oxidizing bactericides such as dodecylbenzyl ammonium chloride can also bring a large amount of foams to copy paper system, to serious shadow
Ring yield rate；If increasing the dosage of non oxidizing bactericide, it is difficult to receive again in use cost if client；It is more numb
Tired is prolonged use non oxidizing bactericide, and copy paper system will produce drug resistance, and then makes the reduction of its using effect.
At present on high-speed paper machine, external some auxiliary agents supplier mostly uses online response type fungicide, such as Suo Li
Think of mixes bleaching liquor and ammonium bromide according to a certain percentage, and the intermediate after hybrid reaction is added in copy paper system；Bark is graceful
Then bleaching liquor and ammonium sulfate are mixed according to a certain percentage, the intermediate after hybrid reaction is added in copy paper system.It is this
Line response type fungicide at the scene in use, need to be equipped with corresponding consersion unit and one to have higher operation horizontal and theoretical
The on-site service personnel of knowledge can have the danger of explosion because once reaction controlling is bad；Further, since bleaching liquor it is light-exposed by
The labile feature of heat, needs to be finished in a short time, thus scene needs constantly to lay in fresh bleaching liquor in case using；More
Importantly, online response type fungicide is also very high to the quality requirements of the molten medicine clear water in scene, the molten liquid medicine meeting of inferior quality
Lead to consersion unit scaling, a degree of fouling can cause consersion unit alarm to be stopped, so as to cause effective
Fungicide can not be added in copy paper system.

It can be mixed with the raw material of mud pit 13.
In the present embodiment, dosing unit has multiple, broken pond 12, clear water reserviors 14, plain boiled water collecting pit 22,21 and of pure pond
Dosing unit there are one being respectively provided on turbid white water chest 24.Dosing unit is in broken pond 12, clear water reserviors 14, plain boiled water collecting pit 22, clear
Set-up mode all same in white water chest 21 and turbid white water chest 24, below only by dosing unit be arranged in broken pond 12 for into
Row explanation.
Dosing unit includes non oxidizing bactericide storage tank 31, oxidizing bactericide storage tank 32, water inlet pipe 33.It is non-oxidizable
Fungicide storage tank 31 is connected with broken pond 12 and stores non oxidizing bactericide, and the setting of oxidizing bactericide storage tank 32 is being damaged
In paper pond 12 and oxidizing bactericide is stored, water inlet pipe 33 is connected with oxidizing bactericide storage tank 32 for being killed to oxidisability
It is passed through water in microbial inoculum storage tank 32.
As shown in Fig. 2, the through-hole 321 being discharged for oxidizing bactericide is offered on oxidizing bactericide storage tank 32.This
In embodiment, the capacity of oxidizing bactericide storage tank 32 is 80-150L, and oxidizing bactericide is to oxidizing bactericide in order to prevent
The corrosion of storage tank 32 is coated with resistant material on the inner wall of oxidizing bactericide storage tank 32.Oxidizing bactericide storage tank 32 is
The closed sieves with inside lining anti-corrosive material.Water inlet pipe 33 and through-hole 321 are located at oxidizing bactericide storage tank 32
Opposite sides so that under flow action of the oxidizing bactericide in water inlet pipe 33 in oxidizing bactericide storage tank 32 from
Through-hole 321 is expelled to broken pond 12, and oxidizing bactericide is added to copy paper system in the case where the bourn acting force of some strength drives
In system, in order to keep the stability of copy paper system, the water at water inlet pipe 33 will remain constant pressure.
The total chlorine number needs detected in copy paper system>0.1mg/L, it is therefore desirable to continuously add oxidizing bactericide.This reality
The addition manner for applying the oxidizing bactericide of example is：By the flow of the constant pressure of water inlet pipe 33, continuously by oxydixing sterilization
Agent is added in broken pond 12, clear water reserviors 14, plain boiled water collecting pit 22, pure pond 21 and turbid white water chest 24.
In the present embodiment, non oxidizing bactericide is added using batch impact type mode, and the addition time is according to micro- life
The breeding cycle of object is determined, and the breeding cycle of general microorganism is 2-4 hours.
