Hazel rod, hazel rind regeneration machine-made charcoal

Abstract

A process of producing charcoal from branches and barks of hazelnut. It comprises, screening and cracking disposed branches, barks of hazelnut, drying the mixed material of branches and barks of hazelnut in a dehydrator, and sending it into a coal-making machine to produce carbon pencils, sending carbon pencils into a charring oven to produce charcoal, the coal content is above 85%, the calorie value is above 8500 kcal, recycling combustible gases produced in making coal to be fuel for burning ceramic products. The invention saves cost and protects resources, and prevent new environment pollution.

Description

technical field [0001] The invention relates to a machine-made charcoal produced by using the waste of agricultural native products, in particular to a mechanism charcoal regenerated from hazel stalks and hazel bark, which belongs to the technical field of comprehensive utilization of waste. Background technique [0002] Charcoal is a porous solid fuel left after incomplete combustion of wood or wood raw materials or pyrolysis under air-isolated conditions. It is widely used because of its high combustion efficiency and no smoke. Traditional charcoal is made of wood with better texture. With the development of society and the gradual reduction of forest resources, the supply of charcoal is becoming increasingly tense. Hazel is a perennial deciduous shrub that is widely distributed in Northeast China, In the low and hilly mountains of North China and Northwest China, nuts are one of the famous native products. In recent years, the development and production of hazelnuts has c...

Problems solved by technology

However, the thinned hazel stalks can only be used as ordinary burning materials, and the hazel skin after deseeding is discarded at will, which is a waste of resources and pollutes the environment

In order to replace valuable wood resources, there was once a technology in the market that used furfural slag instead of wood to make machine-made charcoal, but it could not be popularized because of the low strength, high breakage rate and low yield of the extruded furfural slag sticks. At present, some people are also researching the technology of producing charcoal from wastes such as fruit shells. For example, the Chinese invention patent ZL98112685. The plant stems are made of raw materials, crushed and dried, put into a special machine-made carbon forming machine, and pressed into rods, put the shaped rods into the furnace for desmoke carbonization, and then cool; the crushed materials are 40-60 mesh, and the dried materials The moisture content is lower than 10-15%, the compression molding pressure is 15-25 MPa, the temperature is 150-200°C, the carbonization temperature is 250-400°C, the carbonization time is 8-12 hours, and the heat preservation is 2-6 hours , the cooling temperature is lower than 50~60℃

The above process requirements cannot realize the use of hazel stalks and hazel skins as raw materials to make machine-made charcoal, and this process does not recover the available gas produced in the process of charcoal production, let alone recover the available gas produced in the process of charcoal production. gas, used as fuel to produce other products
