Equipment and method for drying-carbonizing combined treatment of wood material heated by electric heating plate in negative pressure environment

Abstract

The invention relates to equipment and a method for drying-carbonizing combined treatment of a wood material heated by an electric heating plate in a negative pressure environment. The treatment equipment comprises a vacuum tank body, a vacuum acquisition device, an in-tank electric heating device, an electric control cabinet and a control device, wherein the vacuum tank body is also provided witha high-pressure fine water atomization humidifying device, the electric heating device in the vacuum tank body consists of a plurality of electric heating plates, and during use, the electric heatingplates and a to-be-processed wood material are alternately placed in parallel to form a stack, the uppermost electric heating plate and the lowermost electric heating plate of the stack are respectively provided with a heat insulation layer, and a hydraulic pressurizing device is arranged on the top of the stack. The wood material treatment method performs wood material processing treatment by using the wood material treatment equipment. According to the wood material treatment equipment and the wood material treatment method, one-time loading of a wood material can be achieved, wood materialdrying and wood material carbonization treatment or wood material drying-carbonization combined treatment can be carried out in the same equipment, and wood material drying and wood material carbonization treatment can be achieved efficiently, rapidly and efficiently in a high-quality mode.

Description

technical field [0001] The invention relates to a method and equipment capable of drying or carbonizing wood alone, as well as a combined treatment of drying and carbonization in a negative pressure environment, and belongs to the field of wood drying and wood heat treatment (carbonization) modification. Background technique [0002] Wood is a green and renewable biological material, which is environmentally friendly and sustainable. In addition, wood also has beautiful patterns and colors, high strength, and easy processing. It has been widely used in construction and indoor wood products since ancient times. on the production. [0003] Wood is a biological material, and the moisture in wood has obvious effects on the physical and chemical properties of wood. Wet wood is prone to problems such as cracking, deformation, decay and mildew. Therefore, the wood used in construction and wood products must be dried to reduce the moisture content of the wood to the equilibrium mo...

AI Technical Summary

Problems solved by technology

The current carbonization equipment is basically not suitable for preliminary wood drying. Before carbonization, it needs to be dried in other drying equipment, and then the materials are shipped to the carbonization kiln. The operation is cumbersome, complicated, laborious and laborious, and the production efficiency is low.
