Description
Technical field
The present invention relates to be used for contracurrent system through the drier equipment of breadth (web), especially paper.
Background technology
For example there is a kind of equipment according to the FR-A-2771161 under the applicant's name, this equipment has at least one breadth, the gas that are arranged in substantially on its whole width according to the delegation at least that launches along the horizontal direction of breadth and adds hot radiant element, with at least one the transverse convection system in the downstream of the delegation at least of radiating element, this contracurrent system is equipped with suction and blowing device to blow this partial combustion product with suction by the product of partial combustion at least of radiating element generation and towards breadth.This equipment also has a device usually to extract the heating installation body that produces by through the convective exchange between breadth and the combustion product.
Suction and blowing device have mixing arrangement, ventilator for example, owing to several known reasons, described mixing arrangement in the outside of breadth with respect to central longitudinal axis with usually with respect to the big distance of the width of breadth even greatly the mode of distance is laterally mobile.Like that, ventilator must laterally be collected in the combustion product of initial division on the whole width of breadth, mixed combustion product then, and on the whole width of breadth, divide them once more.Such mixing needs a large amount of consumption of energy.
In addition, such equipment has at least along the horizontal direction of breadth and has the suction of remarkable size and blow pipeline.These pipelines are by radiation and convection current dissipation heat energy.Suck the cold air of cooling combustion product in addition in addition.Therefore, the temperature that is blown into the combustion product on the breadth significantly is lower than the temperature of the combustion product that is generated by radiating element.
Although work satisfactorily, such equipment means the remarkable consumption of mechanical energy, also means the remarkable loss of heat energy, therefore causes sizable investment and operating cost, and also takies big surface.Describe a kind of improved system among the WO2005/085729 under the applicant's name, caused the minimizing of mechanical energy consumption and reducing of heat-energy losses, reduced investment and operating cost, and needed littler space.
This drier equipment is characterised in that such fact, promptly, the suction of contracurrent system and blowing device have at least one suction and blowing device, its with respect to the corresponding suction that launches along the horizontal direction of breadth at least and blow pipeline with the breadth of process relatively install, and be positioned in such a way that to such an extent that described combustion product is aspirated and/or blowed to the average optimised mode of vector.Vector representation is sucked and/or is blowed the track separately of the different jet of combustion product.
This optimization significantly reduce combustion product jet track and suction and blow the required mechanical mixture energy of different jet of combustion product.
The shorter track of these of combustion product needs short suction and blows pipeline and corresponding to the reduced size on less surface, it causes by the heat energy of radiation and convection losses obviously littler.
Similarly, be sucked combustion product and the temperature difference that blowed between the combustion product obviously is reduced, increased efficient thus.
Like that, combustion product and can be maximized through the heat transmission between the plane, and also might obtain very-close-coupled drier equipment, wherein combustion product is blowed under the highest possible temperature.
