Problems solved by technology

After the furfural slag is removed from the debris, the rod making machine is pressed into furfural slag rods, dried and carbonized, and then cooled to obtain mechanism charcoal. This process uses bagasse as raw material, with few resources and narrow application range.

Embodiment 1

[0020] 100kg of vinblastine waste slag extracted from vinblastine by homogenate (homogenized extraction, periwinkle stems and leaves have been crushed to a particle size of less than 2mm) was extruded at 120°C. After molding, the carbon rod size was: 50cm long, and the shape was A square with a side length of 5cm and a hollow inner diameter of 2cm is placed in a carbonization furnace for carbonization. The first stage temperature is from room temperature to 120°C for 15 minutes; the second stage temperature is 300°C for 240 minutes; the third stage temperature is 400°C , time 180 minutes. The products are charcoal and flammable volatile gas, which is burned through the combustion chamber to provide heat source for the carbonization furnace to heat up. Among the gases produced by decomposition, water, tar and wood vinegar. When the temperature reaches 450°C, carbonization is completed, and the furnace is closed and cooled to room temperature to obtain mechanism charcoal. The ...

Embodiment 2

[0022] Pulverize 1000kg of tea waste dregs for extracting tea polyphenols, the particle size of which is less than 2mm, and extrude them at room temperature. The temperature ranges from room temperature to 120°C, and the time is 20 minutes; the second stage temperature is 350°C, and the time is 220 minutes; the third stage temperature is 450°C, and the time is 220 minutes, and the carbonization is completed. The products include charcoal and combustible volatile gas, and the furnace is sealed and cooled to room temperature to obtain mechanism charcoal. The yield is 43%. According to the national standard, the calorific value of the air-dry base cartridge is 34MJ / kg, and the fixed carbon content is 75%.

Embodiment 3

[0024] 500kg of camptothecin-extracted camptothecin seed waste residue is pulverized, and its particle size is less than 1.5mm, and is added to a molding machine at 140°C for molding. After molding, the rod size is: length 55cm, outer diameter 6cm, inner diameter 2cm, and put it into a carbonization furnace. Carry out carbonization, the temperature of the first stage is from room temperature to 120°C, and the time is 20 minutes; the temperature of the second stage is 350°C, and the time is 240 minutes; the temperature of the third stage is 450°C, and the time is 220 minutes. Produce charcoal and combustible volatile tail gas. The combustible volatile gas is burned through the combustion chamber to provide a heat source for the carbonization furnace to heat up. After the carbonization is completed, stop the heating, close the furnace, cool to room temperature, and release from the furnace to obtain the finished charcoal. The yield rate is 46%. According to the national standard...

Abstract

The disclosed preparation method for charcoal comprising: crushing the solid waste from extracted traditional drug or plant to extrude into bar-form; loading the product into retort for charring reaction with three stages for 10-30min at 120Deg, 200-400min at 120-350Deg and 100-300min at 350-450Deg, respectively. Wherein, firing the exhaust gas in combustion chamber to provide heat source. This invention has yield rate as 40-55% with low energy consumption and little pollution.

Description

Technical field: [0001] The invention relates to the field of treatment of waste residues extracted from traditional Chinese medicines or herbal medicines, in particular to a method for manufacturing machine-made charcoal from solid wastes extracted from traditional Chinese medicines or herbal medicines. Background technique: [0002] Solid waste from extraction of traditional Chinese medicine or herbal medicine mainly refers to the solid residues generated during the whole process of extraction and production of traditional Chinese medicine and herbal medicine. The total amount of solid waste extracted from traditional Chinese medicine or herbal medicine produced in my country every year is tens of millions of cubic meters. For a long time, most of these plant residues produced by the Chinese medicine or herbal medicine processing industry are thrown away as waste. Utilization has always been a problem that people want to solve, and processing the above substances into charc...
