Background

The paper is a sheet-shaped fiber product used for writing, printing, drawing or packaging and the like, China is the country invented with paper at the earliest time in the world, and according to archaeological findings, China already has hemp fiber paper in the period of Western Han dynasty (206 years before the Gongyuan to 8 years before the Gongyuan). At present, the formation of paper is mainly divided into two basic processes of a pulp process and a paper making process, wherein the pulp process is to dissociate plant fiber raw materials into natural color pulp or bleached pulp by a mechanical method, a chemical method or a combination method of the mechanical method and the chemical method; the papermaking process combines pulp fibers suspended in water through various processes into paper sheets meeting various requirements.

In the paper making process, a pulp machine is generally adopted for making paper in the paper sheet forming process, specifically, after the paper pulp is made, the paper pulp is conveyed and laid on a pulp board in the pulp machine, and then the paper pulp on the pulp board is heated and dried by hot air, so that the paper sheet is obtained. In the prior art, because the temperature of hot air required by a pulp machine in the pulping and papermaking technology is not high, the existing pulp machine generally preheats fresh air outside the pulp machine by adopting a steam heater, then directly sends the fresh air into a dryer, then carries out secondary heating in the dryer by the steam heater, and finally blows the fresh air onto the pulp board by a fan to dry paper pulp on the pulp board by hot air impact. In the process, hot air required by drying the paper pulp on the pulp board needs to be heated twice by the steam heater, and the heating cost is very high.

However, in the prior art, the steam heater usually uses dry hot air generated by large power to dry the paper pulp on the pulp machine, and then directly discharges the hot air, so that the resource loss is increased, the energy utilization rate is low, more energy is wasted, more electric energy is consumed, the production cost is increased, and the production benefit is reduced.
