Problems solved by technology

[0002] In the carbonization furnace for producing charcoal, there are: first, the carbonization rate is low, because the biomass fuel material is in contact with the air during the carbonization process, causing the carbon to be oxidized into carbon monoxide and carbon dioxide by the oxygen in the air; the second is the biomass fuel material After carbonization, it cannot be coole

Embodiment Construction

[0012] Reference attached figure 1 ——attached image 3

[0013] The high-efficiency carbonization furnace consists of a large fire pipe 1, a fire pipe switch 2, a cold air pipe 3, an air pipe switch 4, a furnace cover plate 5, a small fire pipe 6, a fire inlet 7, a U-shaped groove 8, a furnace body 9, and an outlet. Flue 10, smoke outlet pipe 11, wood gas flue 12, water jacket 13 (or snake hollow pipe 25), flue cover plate 24, wood gas chimney 14, water inlet pipe 15, water outlet pipe 16, valve 17, valve 18 , Water pump 19, water tank 20, water tank 21, valve 22, and valve 23 etc. are formed.

[0014] The walls around the body of heater 9 have multiple horizontal U-shaped grooves 8, and between the two U-shaped grooves 8 is a boss, which wears a plurality of fire tubes 6 in the boss, and the small fire tube 6 is made of a metal material. One end of the fire pipe 6 communicates with the fire inlet 7, and the other end communicates with the flue 10, and a U-shaped groove 8 i...

Abstract

The invention discloses a high-efficiency carbonization furnace, which comprises a furnace body, a main fire pipe, a cold air pipe, a fire accessible duct, fire tubes, a flame inlet passage, an fume outlet duct, a fume outlet pipe, U-shaped grooves, a wood gas flue, a water jacket (or snaking hollow section), wood gas chimney and the like. The periphery of the carbonization furnace is provided with a plurality of the U-shaped grooves, and the inside of the carbonization furnace is provided with a plurality of the fire tubes of which two ends are connected with the fire accessible duct and the fume outlet duct respectively. Biomass fuels are placed in the carbonization furnace, the cover board of the furnace body is covered, flue gas passes through the small fire tube to heat the biomass fuels, and the carbonization is started and speeds up with the continuous rise of the temperature. When the carbonization of wood charcoals is finished, an air blower is started; and cool air enters the cold air pipe and the small fire tube 6 to absorb heat of the wood charcoals and flows out from the fume outlet duct to enter a heat drying chamber for drying the raw materials of the biomass fuels. Wood tar and the wood gas generated during the carbonization flow into the wood gas fuel along the U-shaped grooves, and the wood tar is cooled by the water jacket (or snaking hollow section) and changed into solid.

Description

Technical field: [0001] The invention relates to a high-efficiency carbonization furnace technical background: [0002] In the carbonization furnace for producing charcoal, there are: first, the carbonization rate is low, because the biomass fuel material is in contact with the air during the carbonization process, causing the carbon to be oxidized into carbon monoxide and carbon dioxide by the oxygen in the air; the second is the biomass fuel material After carbonization, it cannot be cooled quickly in a closed environment, but is cooled by adding water or natural cooling, and the heat is not used; third, in the early stage of carbonization, the use of ignited biomass fuel materials slowly spontaneously ignites, the carbonization speed is slow, and the oxidation is serious , causing losses; Fourth, the by-product wood tar is not effectively cooled and volatilized. Invention content: [0003] The object of the present invention is to provide a high-efficiency carbonizatio...
