Rice husk rapid charring method and carbonization furnace

Abstract

The present invention discloses a method for fast carbonizing rice husk and a carbonizing furnace. The method is that self-igniting type rice husk is directly heated to manufacture char, the bottom of the carbonizing furnace is provided with a layer of the rice husk or other raw materials as a fixing layer, and igniting material is used to ignite the fixing layer. The method of continuously feeding above the furnace and the method of inducing air under the furnace are adopted, after the rice husk is carbonized, the air inducing is stopped, and a spraying cooling method is used to activate and cool the rice husk. The present invention combines the fast carbonizing technology and the activating technology subtly to reduce the carbonization time, ensure the continuous production, improve the production efficiency and save the production cost. The present invention adopts the technology of spraying hydrosphere for cooling and activating, which effectively improves the char absorption capability and ensure that the char has better activity. The finished product of a rice husk char of the present invention has wide application range and can be used as fertilizer sustained-release agent, feed additive, smelting melting agent, food additive, medical additive etc. The present invention can make the raw material into granules, then is carbonized to be directly used in absorbent, antistaling agent and order absorber and also can be used as the fuel for high-grade barbecue and field operation personnel.

Description

technical field [0001] The invention relates to a carbonization method and a carbonization furnace for raw materials such as rice husks or other plant straws. Background technique [0002] As we all know, in the vast rice producing areas of my country, rice husks are used as leftovers of rice processing plants, and most of them are discarded. In recent years, the technology of using rice husk, sawdust, and crop stalks to make charcoal has developed to a certain extent, providing certain technical support for the development and utilization of renewable energy in my country, and has made great progress. However, so far, the technology in this area is not perfect and not supporting. At the same time, there are complicated processes that are difficult to master, and some links of the equipment are not matched and out of touch, so that the existing equipment and technology cannot play a full role. It is difficult to promote and integrate in the vast rural areas. universal. [...

AI Technical Summary

Problems solved by technology

Although this method saves fuel, the cost of carbon production is increased by making rice husk into rods, the loss rate of charcoal burning is high, and the carbonization time is longer

The finished charcoal is mainly used as fuel, with a single purpose and a small scope of use. Due to the comparison of coal, coke, and charcoal, the cost and profit of rice husk charcoal are not dominant, and the promotion and development are severely restricted.
