Moisture drying control device and control method for silk drying machine

Abstract

The invention discloses a moisture drying control device for a silk drying machine, which comprises a drum silk drying machine, a hot air blower, steam spraying equipment and dust removal equipment; the hot air blower communicates with the drum silk drying machine through a hot air pipeline; the The spray steaming equipment communicates with the hot air pipeline through a steam spraying pipeline; the air inlet end of the dust removal equipment communicates with the drum silk drying machine through a moisture discharge pipeline, and its air outlet connects with the hot air pipeline through a circulation pipeline. Connected, the hot and humid tail gas after dust removal is heated and diluted by fresh hot and humid air in the hot air pipeline, and then blown into the drum silk drying machine again; There are hot air valves, spray steam valves, tide valves and circulation valves with adjustable openings respectively; Air pollution can also reduce energy consumption and improve the production efficiency of enterprises.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a moisture drying control device for a silk dryer and a control method thereof. Background technique [0002] Tobacco is an important economic crop in China. The tobacco industry occupies a very important position in the economies of all countries in the world. So far, the tobacco industry is still a very large industry in all countries. my country is a big tobacco production and sales country in the world. In the past ten years, my country's cigarette production and sales have occupied a large share in the world. In the production of cigarettes, tobacco as the main raw material occupies a very important position, and the quality of tobacco is directly related to the quality of smoke. In the process of tobacco processing, the drying of shredded tobacco is a very important process. The quality of shredded drying is not only related to the filling rate of shredded tobac...

AI Technical Summary

Problems solved by technology

[0003] During the drying process of shredded tobacco, the moisture content of shredded tobacco to be dried on the feed belt of the drum dryer is 22.0% to 40.0%, and the moisture content of shredded tobacco after drying on the discharge belt is 11.0% to 15.0%. After drying the shredded tobacco, the temperature of the drying air decreases and the moisture content increases. The existing moisture drying control device of the shred dryer usually discharges the drying tail gas with low temperature and high humidity into the atmosphere.

The hot and humid drying tail gas is discharged into the atmosphere, which not only causes the local air temperature to be too high and has a high moisture content, which affects the normal air environment, but also needs hot and humid hot air to dry the shredded tobacco during the shredded tobacco drying process, which requires a lot of consumption. More energy and water sources are used to generate dry hot air and water vapor, and the hot and humid drying exhaust gas has not been properly utilized, which increases the drying cost of shredded tobacco and reduces the production income of the enterprise
