Abstract

The embodiment of the invention discloses a method and system for controlling the temperature of the process hot air of a warming and humidification device. The method includes injecting steam flow into a circulation wind pipe by adjusting a steam jet firstly, and adjusting, as an auxiliary means, the temperature of the process hot air by adjusting the steam flow amount of a circulation wind heater. The method no longer mainly depends on the circulation wind heater, thereby solving the problem that the adjustment of the temperature of process hot air is severely lagged behind due to the influence of the thermal inertia of radiating tubes of the circulation wind heater. No fresh air is needed for controlling the temperature of the process hot air, which prevents fluctuation of air flow pressure of the process hot air in a roller due to change of supplemented fresh air. The problems of unstable travelling speed and water absorption rate of materials in the roller also can be prevented.

Description

technical field [0001] The invention relates to the field of automation control, in particular to a method and system for controlling process hot air of warming and humidifying equipment. Background technique [0002] In the cigarette shred process, drum-type heating and humidifying equipment is widely used in the production line. The main task of the process is to increase the temperature and moisture content of the material, make the material stretch and loosen, improve the processing resistance, and improve the sensory quality and physical properties. . In the process of increasing temperature and humidifying, the stability of process hot air temperature is particularly important. It is the most important parameter to reduce material crushing, increase material loosening rate, and affect material moisture absorption speed and moisture absorption capacity. It directly affects the sensory quality and physical properties of products in process. performance etc. [0003] Th...
