Description
Technical field
The present invention relates to the equipment of paper industry, in particular to arriving a kind of papermaking drying machine drying section.
Background technique
Drying section of paper machine generally refers to part between paper machine squeezing unit and coater unit and coater unit and press polish
Part between unit.It is different according to its relative position in whole production line of paper machine, it is divided into preceding drying, middle drying and does afterwards
It is dry.For large cylinder paper paper machine, major diameter drying cylinder also belongs to Dryer Section of Paper Machine.The major function of Dryer Section of Paper Machine is de- to wet web
Water guarantees that page reaches the mass dryness fraction of finished paper, while adjusting page vertical and horizontal moisture content and quantifying consistent, guarantee page characteristic.
From squeezing unit come out wet web, due to paper product and squeezing form difference, mass dryness fraction 30% -47% it
Between.After wet web enters drying section, by a series of drying cylinders being heated, big portion's moisture is evaporated, reaches finished paper 96% or so
Mass dryness fraction requirement.Evaporation process needs a large amount of thermal energy, these thermal energy usually supply in vapour form.Drying section is usually in paper machine
It consumes energy maximum.Thermal energy is transmitted to paper web from steam, needs sizable heat transfer area, therefore drying section is most huge in paper machine
Unit.
In addition, drying page using steam heated cylinders, overall efficiency is low, and energy consumption is high, and there are also great amount of carbon dioxide etc.
Pollutant emission, not environmentally.The hot conveying flow of conventional paper machines drying section, boiler convert water to high-pressure water vapor, and efficiency is about
85%；High-pressure water vapor is transported to drying cylinder by steam pipe network, and efficiency is about 88%；Drying cylinder transfers heat to paper, efficiency again
About 63%, the overall efficiency of whole system only has 47%.
Summary of the invention
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of using hot wind directly to wet on steel mesh belt
The papermaking drying machine drying section that paper is dried, overall efficiency is high, and low energy consumption, environmental protection.
To achieve the above object, the present invention is achieved by the following technical solutions: a kind of papermaking drying machine drying section, packet
Heat exchanger, air outlet, driven roller, setting are included in driven roller and with driven roller) the steel mesh belt of cycle rotation, the steel
Mesh belt includes the upper steel mesh belt being arranged in above driven roller) and the lower steel mesh belt that is arranged in below driven roller, the upper steel
Multiple upper hot bellows dried from top to bottom are equipped with above mesh belt processed, lower section is equipped with multiple lower hot bellows dried from the bottom up,
The lower steel mesh belt is attached in multiple first rollers, and the outlet air end of the heat exchanger passes through the first exhaust fan and upper hot wind
Case, lower hot bellows are separately connected, and the air outlet is arranged near upper steel mesh belt, are connect with heat exchanger air intake.
It further illustrates, the heat exchanger is made of more conduction oil oil pipes, in adjacent two conduction oil oil pipes
Conduction oil flow direction on the contrary, and adjacent two conduction oil oil pipes be equipped with gap.
It further illustrates, the second roller for supporting upper steel mesh belt is additionally provided between the lower hot bellows of adjacent two.
It further illustrates, the second exhaust fan is provided between the air outlet and the air intake of heat exchanger.
It further illustrates, the upper hot bellows are corresponding with lower hot bellows upright position.
It further illustrates, is respectively arranged with tuyere on the upper hot bellows and lower hot bellows.
Compared with prior art, the invention has the following beneficial effects: pass through temperature after heat exchanger using present apparatus cold wind
Degree is increased into hot wind, and hot wind vertically blows to steel mesh belt from upper hot bellows and lower hot bellows by the effect of the first exhaust fan, will
Heat transfer takes away the high temperature being evaporated in paper, high humidity steam to page, compared with conventional paper machine drying section, reduces
Energy conversion times, shorten transport path, and the overall efficiency of heat can reach 90% or more.From whole flow process it can be seen that,
Material utilizes and energy conversion is that one closed, circular flow in holonomic system, and last product is water, does not generate any dirt
Dye.
