Problems solved by technology

[0006] The purpose of the present invention is to overcome the problems existing in the prior art, to provide a flue gas recycling internal heating biomass carbonization furnace, which can prepare biomass charcoal that can recycle combustible gas generated in the thermal cracking process, and solve the problem of biomass carbonization. The carbonization device cannot be moved to achieve on-site treatment, the carbonization efficiency is not high, the secondary pollution such as tar fume is serious, and the operation of increasing the amount is inconvenient, etc.
The operation is simple, the raw materials are cheap and easy to obtain, and can be moved, which is convenient for on-site carbonization and utilization of agricultural and forestry waste, and solves the problem of difficult material collection and transportation

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] like Figure 1~Figure 2 As shown, the primary air inlet channel 5 includes a primary air inlet, a damper and ash receiving chamber, the primary air inlet is connected with the ash receiving chamber, and the whole is made into the shape of a drawer, and the primary air inlet is controlled by controlling the opening of the ash receiving drawer. The size of the air volume, after the carbonization process, pull out the drawer and pour out the burned ashes.

[0032] The packing channel 4 is composed of a packing port and a packing port door, and the packing port is a square structure, such as figure 1 As shown, in the carbonization process, a small amount of biomass is added into the combustion chamber through the filling port to provide heat for the carbonization of biomass fuel in the carbonization chamber.

[0033] The heat conduction sheet can be composed of 4 first...

Abstract

The invention discloses a smoke-reuse internal heat type biomass carbonization furnace. The carbonization furnace comprises a carbonization furnace body, and also comprises a combustion chamber arranged in the carbonization furnace, a primary air inlet channel connected with the bottom of the combustion chamber and a filler channel connected with the bottom of the combustion chamber, and a carbonization chamber is formed between the carbonization furnace body and the combustion chamber; and the top of the combustion chamber is connected with the outside of the carbonization furnace body, a cross smoke reuse pipeline is arranged at the lower portion of the combustion chamber, a cross secondary air inlet pipeline is arranged at the upper portion of the combustion chamber, and the outer wall of the combustion chamber is connected with heat conduction sheets. The smoke-reuse internal heat type biomass carbonization furnace has the advantages of simple operation, strong adaptability to a raw material, cheapness and easy obtaining of the raw material, realization of in-situ carbonization treatment of the biomass raw material, transportation and treatment cost reduction, small pollution to the environment, and good application prospect.

Description

technical field [0001] The invention relates to the field of biomass carbonization, in particular to an internal heating type biomass carbonization furnace for flue gas reuse. It is suitable for on-site carbonization and on-site utilization of agricultural and forestry waste, which solves the problems of difficult material collection and transportation. Background technique [0002] my country's biomass resources are very rich, and a large amount of crop straw is produced every year. Due to the lack of feasible treatment and application technology, except for a small part used as feed, fuel and industrial fuel, most of them are directly burned in the field, causing serious environmental pollution. Pollution. In addition, some stalks are directly discarded, wasting precious natural resources. The natural decay of waste straw, rice husk and other biomass materials will produce serious CH 4 , seriously destroying the ozone layer and exacerbating global climate change. Theref...
