High-temperature physical carbonization method of carbide furnace and wood

Abstract

The invention provides a high-temperature physical carbonization method of a carbonization furnace and wood. The carbide furnace comprises a horizontal carbonization tank, wherein one end of the horizontal carbonization tank is provided with an end socket, the other end of the horizontal carbonization tank is provided with a tank cover, the periphery in the carbonization tank is provided with a heat-conducting pipe through which heat-conducting media flow, the heat-conducting pipe is communicated with a heat-conducting oil feeding device arranged outside, and the heat-conducting oil feeding device is composed of a heat-conducting oil pump and a heat-conducting oil heater; the middle of the carbonization tank is provided with a lace bar frame used for containing the wood; a vacuum pumping machine connected with the carbonization tank through a vacuum pumping pipe is arranged outside the carbonization tank; the carbonization tank is connected with an external steam generating and feeding device through a steam connection pipe; the carbonization tank is further provided with a safe valve, a pressure gage and a wood still gas releasing pipe with a switch valve. The high-temperature physical carbonization method comprises the steps that (a) the wood is placed in the furnace; (b) a steam valve is opened for humidification; (c) vacuum pumping and drying are conducted; (d) temperature is increased and carbonization is conducted; (e) carbonized wood is manufactured after the temperature is decreased and preserving is conducted. The high-temperature physical carbonization method has the advantages that the used carbonization furnace is simple in structure, safe to operate and use, and convenient and reliable to use, the carbonization process is simple, the carbonization effect is good, and a use range of the carbonized wood is enlarged.

Description

technical field [0001] The invention relates to a high-temperature physical carbonization method of wood and a carbonization furnace, belonging to the technical field of wood physical treatment and corresponding treatment devices. Background technique [0002] At present, the wood used in outdoor engineering construction, such as the wood used in courtyards, flower racks, corridors and floors, etc., is mostly not dried, so these woods that have not been dried are processed into corresponding products for installation and use. After that, in less than 2 or 3 years, you will find problems such as shrinkage, swelling, cracking, decay, insects, deformation, etc.; even if they have undergone some chemical anti-corrosion treatment, the chemical composition will slowly be exposed to the rain and the sun in the future. Therefore, conventional chemical anti-corrosion treatment cannot solve the problems of dry shrinkage, wet expansion, cracking, deformation and so on. Contents of th...
