A continuous carbonization furnace for bamboo

Abstract

The invention discloses a bamboo substance continuous carbonization furnace which comprises a heat supply system, a carbonizing system, and a gas and water recovery system. The heat supply system is connected with a furnace body of the carbonizing system through a hot air annular pipe. A water ring type pressurizing machine is connected with a coal gas storage cabinet of the gas and water recovery system. The furnace body of the carbonizing system is connected with the gas and water recovery system through a coal gas collecting annular pipe on a furnace top platform. A cooling cavity of the carbonizing system is connected with the coal gas storage cabinet of the gas and water recovery system through a pipeline. The gas and water recovery system is located at the right end of a bottom plate. The bamboo substance continuous carbonization furnace is high in dry distillation speed, high in char formation rate, high in heat utilization rate, high in resource comprehensive utilization rate, free of waste in the process and free of pollution to the environment.

Description

technical field [0001] The invention relates to a continuous carbonization furnace for bamboo materials, in particular to a carbonization furnace for continuous production of bamboo materials. Background technique [0002] my country is a big producer of charcoal, with an annual charcoal output of up to 10 million tons. With the rapid development of the national economy, the demand for charcoal is also increasing year by year. Since the main raw material of charcoal is natural wood, the demand for natural wood has also increased. my country is rich in bamboo resources, and a large amount of bamboo chips and other products are produced in the process of bamboo utilization. In order to effectively protect forestry resources, bamboo charcoal has now been used instead of charcoal, which can greatly reduce the demand for natural wood and is widely used in Every aspect of home life. Biomass carbonization is to use the principle of thermochemical reaction to prepare green renewabl...

AI Technical Summary

Problems solved by technology

[0003] 1. The reaction gas is burned and heated inside the furnace body, which causes uneven heating of the materials in the furnace body. Due to the natural cooling of the generated carbon products or direct water cooling, some carbon products spontaneously ignite or react with water, and the carbon generation rate decreases. If water cooling , The direct discharge of organic compounds such as tar in the cooling water will cause environmental pollution;

[0004] 2. The temperature of the removed carbon products is very high, and the heat in the reaction process cannot be effectively utilized, resulting in waste of heat;

[0005] Three, only charcoal products are obtained in the reaction process, and the products such as water gas, bamboo vinegar liquid and bamboo tar cannot be recycled, resulting in waste of resources, which will pollute the environment when discharged into the atmosphere
