Embodiment Construction

[0031] 1. Component composition and connection relationship

[0032] Such as Figure 1-5 As shown, a biomass carbonization equipment includes a carbonization furnace, a retort barrel 8, a guide rail 5, a guide rail car 6, and a trolley required for the retort barrel to enter and exit the carbonization furnace. A slope 16 of 5-10 degrees is formed between the extension direction 15 of the carbonization furnace body and the ground plane 17 . The retort barrel 8 moves in the carbonization furnace through two guide rails 5 fixed on the inner wall of the carbonization furnace and the guide rail car 6 moving on the guide rails under the action of gravity; the stay of the retort barrel 8 on the guide rail 5 is controlled by a The movable gear rod 25 is controlled, and the rotation of the retort barrel is realized by a transmission rod 19 passing through the furnace wall.

[0033] The carbonization furnace is composed of an outer furnace wall 1, an inner furnace wall 3, a combustion...

Abstract

The invention discloses biomass carbonization technology and equipment. The equipment comprises a carbonization furnace, destructive distillation barrels (8) and movement and rotation auxiliary components thereof, and pyrolysis oil gas burning components. The carbonization furnace comprises a combustion chamber (11), internal and external cavities (4, 2), an air-return channel (21), guide rails (5) and sealing doors (10, 13), and the body of the carbonization furnace has a slope of 5-10 degrees. Each destructive distillation barrel comprises a barrel body, oil gas outlet and a rotation shaft. The guide rails (5) are fixed on bases (23) of an inner furnace wall (1) of the carbonization furnace. A guide rail car (6) runs on the guide rails. The destructive distillation barrels are hung below the guide rail car. The movement of the guide rail car is controlled by a metal rod which is in parallel with the guide rail. The rotation of the destructive distillation barrels is completed by a transfer bar (19) which passes through furnace walls. Pyrolysis oil gas is guided to below the destructive distillation barrels through a U-shaped pipe (9) which is connected with the gas outlet of the destructive distillation barrels. When the pyrolysis oil gas meets hot air of a combustor, the pyrolysis oil gas burns to heat the destructive distillation barrels, and carbonation energy is provided and air pollution can be avoided. The biomass carbonization technology and the equipment are suitable for carbonation of straws and other biomass in units of rural villages or families.

Description

technical field [0001] The invention relates to a biomass carbonization process and equipment, in particular to a biomass carbonization method and equipment suitable for rural natural villages or households. Background technique [0002] China is a large agricultural country, with an annual output of about 500 million tons of straw. The effective utilization rate is low, and straw burning is serious, which not only causes waste of resources, but also pollutes the environment. If biomass such as straw can be carbonized in an operational way, and then applied to farmland in an appropriate way (this is biochar technology), 460 million tons of CO can be recovered and fixed from the atmosphere every year. 2 , Increase grain production by 180 million tons. The current international carbon market price is per ton of CO 2 About 130 yuan. Based on this estimate, only the two benefits of carbon sequestration and grain production increase can increase the national agricultural econo...
