Description
Technical field
The utility model is related to paper mill technical field of water treatment equipment more particularly to a kind of paper-making drying cylinder to be followed with boiler water
Ring processing system.
Background technology
Currently, the existing import drying cylinder of my one paper machine room of company, oneself uses 4 years, and boiler institute enters drying cylinder for steam
(i.e. paper-making drying cylinder), it is desirable that pressure 1.35MPa, evaporation capacity 10t/h, drying cylinder do not have external water source, and discharge condensed water is through carbonated drink
Separator-water pump-oxygen-eliminating device-feed pump-economizer-boiler drum.Steam-water separator recovered overhead steam is returned through heat pump
It participates in doing work again to drying cylinder.Condensate return accounts for the 60-70% of boiler whole water consumption.It is caused because of brown iron oxide plugging every
Pigging need to be shut down within two months.
Wherein it should be added that：Cylinder iron drying cylinder is used as the critical component that paper is dried to paper machine.It is manufacturing
In quality requirement mustn't have penetrate with excessive sand holes, in order to increase paper smoothness, it is desirable that drying cylinder outer surface polishing and handle
Inner surface Xuan light makes entire cylinder wall keep thickness consistent, and the safety, balance and heat transfer everywhere to ensure drying cylinder are uniform.Drying cylinder
Effect be for drying the moisture in page, ornamenting paper.
It will be apparent that the harm of above-mentioned Ferric oxide scale is very big, it is easy to cause boiler water quality deterioration：Due to boiler inner tubal wall
Corroded, a large amount of iron ion and corrosion product enter boiler, and boiler water quality is caused to deteriorate or take improperly furnace stopping maintenance
Method, when boiler startup, the iron-holder of stove water is up to hundreds of micro- gram per liters, even more than every liter of kilogamma, and the iron-holder of stove water is inclined
Greatly, cyclone separator collapses or misoperation causes steam-water separation not in time, and the iron-holder of steam also can be bigger than normal.
Cause to reduce boiler heat-transfer coefficient or water screen tube overheat：Tube wall uneven heating, amount of scale buildup is different, the higher knot of temperature
Dirt is thicker.Cause fouling corrosion：Heating surface metal is thinning, perforate, Ferric oxide scale is easy to be formed at the high position of thermic load.Pass through
Workshop condensate return flow feedback adjustment effect, on inspection and the discovery oxygen-eliminating device deoxygenation pipeline that consults reference materials is too thin, the row of cannot be satisfied
Oxygen condition opens oxygen-eliminating device safety valve to increase deoxygenation amount, and as a result workshop circling water flow rate is slightly unimpeded, but fails to reach expected effect
Fruit.It will be apparent that the primary structure of existing processing system is only by steam-water separator-water pump-oxygen-eliminating device-feed pump-province
The brief structure such as coal device is constituted, and the water treatment capacity of synthesis is poor, and especially detergent power is poor be easy to cause subsequent pipeline
It blocks.
