Firing technology of high-quality machine-made bamboo biomass charcoal rods

Abstract

The invention discloses a firing technology of high-quality machine-made bamboo biomass charcoal rods. The method comprises steps as follows: a, machine-made bamboo biomass rods extruded by an extruder at the high temperature are stacked in a kiln; b, manual kiln sealing and ignition are performed; c, intermittent oxygen supply is performed on the machine-made bamboo biomass rods at 50-750 DEG C with an earth kiln sectioned carbonized method, low-temperature carbonization is performed, and the carbonization process sequentially comprises four stages including drying, pre-carbonization, carbonization and refinement; d, the refined machine-made bamboo biomass charcoal rods are cooled twice through water spraying, the temperature is adjusted to 60 DG C or below, the kiln is opened and cooled, and the charcoal rods are taken out; e, the cooled machine-made bamboo biomass charcoal rods are subjected to humidifying treatment. Compared with the prior art, the firing technology has the advantages that the machine-made pure bamboo biomass charcoal rods are taken as raw materials, the low-temperature sectioned carbonization and high-temperature quick refinement methods are adopted, volatile components are thoroughly volatized, the charcoal rods are hard in character, have high combustion value and have no smoke, odors or toxins during combustion.

Description

technical field [0001] The invention relates to a method for firing charcoal rods, in particular to a firing process for high-quality bamboo biomass-made carbon rods. Background technique [0002] In the face of increasingly prominent problems such as the crisis of fossil energy fuels and the destruction of the global ecological environment, the development of renewable biomass clean energy has become the main direction of the development of the world's energy economy. my country is a big producer of biomass resources, rich in various biomass resources, such as crop straw and forestry residues. The traditional utilization methods of these biomass resources are direct combustion or open burning, which not only causes the disadvantages of low energy conversion efficiency and large resource consumption, but also has a subtle impact on the environment. [0003] Barbecue, the most primitive cooking method of human beings, and it has continued to this day, is to heat the fuel to ...

Problems solved by technology

At present, domestic and foreign production mechanism carbon, in order to pursue high carbon rod forming rate, easy to ignite, high carbon yield, and short production cycle, the carbon rod does not reach the refining stage during firing, and the carbonization temperature is generally 300-500°C. This will result in incomplete volatilization of the volatile components of the machine-made carbon, harmful substances may be produced when the binder is burned, and spontaneous combustion may occur when the storage density is high, burning too fast, and the calorific value is not high, etc.

[0007] Low-temperature carbonization is used in the production process of existing biomass-made carbon rods. In order to improve the carbon yield, the carbon rods have not been refined at high temperature, resulting in incomplete volatilization of volatiles in the carbon rods. Secondly, many processes involve binders, ignition agents, combustion-supporting Chemicals such as chemical agents are not completely volatilized during low-temperature carbonization, which will lead to excessive discharge of toxic substances during use, which is harmful to food or directly to the human body, and increases the cost in the production process
