Description
Summary:In the construction industry, a special place is occupied by the lumber preparation and support. Their qualified production at enterprises of the corresponding profile involves wood desiccation to standard moisture content. Since wood desiccation is a complex technological process and mistakes made during its implementation, as a rule, appear closer to the end of the process, their correction takes a long time and is not complete. As a result, the desiccation cost increases, as well as the volume of woodworking waste, and the quality of finished products decreases, which, of course, is not acceptable for the enterprise. Prospects for improving product quality are in the use of an automatic climate control system in the drying chamber. Lumber drying enterprises are very interested in the introduction of equipment for drying chambers automating at any technological stage. In this article, we consider a drying chamber of periodic action with a transverse-vertical circulation of the drying agent, which is forced by centrifugal fans, where steam is used for heating and heat treatment of wood. The introduction of an automatic climate control system in the drying chamber involves the selection of appropriate equipment, the introduction of devices for monitoring the state of the drying agent in the chamber, regulatory bodies, and regulators. Consideration of the available controller and other equipment is supposed to be carried out based on the principles of constructing rational modes to ensure an acceptable technological process of wood desiccation and the use of a virtual model implemented in the VisSim software environment.
