Problems solved by technology

China is the first country in the world to produce charcoal. It adopts indigenous methods to produce charcoal, but there are generally the following problems: first, the output of indigenous charcoal is low, the quality is not easy to guarantee, and it occupies a large area; secondly, it pollutes the environment, causing air pollution, and labor intensive
[0003] At present, the preparation of activated carbon is mainly made by chemical activation of coal. However, due to the non-renewability of coal and the pollution caused by the chemical activation process, chemical activation of carbon can no longer meet the needs of the development of the times.

Embodiment 1

[0066] see figure 1 , a carbonization process based on constant temperature carbonization, the carbonization process comprises the following steps:

[0067] S1. Powder: the wood is crushed into sawdust by the crushing device;

[0068] S2. Feeding: the sawdust is transported to the drying device by the conveying device for drying;

[0069] S3. Drying: the sawdust is heated and dried in a drying device, the heating temperature of the wood is 200-250 degrees Celsius, and the drying duration is about 16-25 minutes;

[0070] S4. Intermediate feed: the dried sawdust is conveyed into the carbonization device by the intermediate feed screw;

[0071] S5. Carbonization: the temperature in the carbonization device is W1, the temperature W1 is a fixed constant temperature value, and the carbonization duration is T1;

[0072] S6. Charcoal production: after the wood chips are charcoalized, enter the water-cooling structure for cooling to obtain the produced charcoal.

[0073] In the ste...

Embodiment 2

[0082] Such as Figure 2-8 As mentioned above, the present invention also discloses a charcoal production equipment based on constant temperature carbonization, including a pulverizer, a conveyor belt, a drying furnace, a carbonization device, a combustion device and a physical activation device. The pulverizer, conveyor belt, drying The furnace, the carbonization device and the physical activation device are connected in sequence, and the combustion device is connected with the drying furnace, the carbonization device and the physical activation device. The outlet end of the steam furnace of the combustion device is connected to the cavity and the activation drum, one outlet end of the carbonization furnace is connected to the inlet end of the combustion furnace, and the other outlet end of the carbonization furnace is connected to the feeding screw. The outlet end of the combustion furnace is connected with a drying furnace.

[0083] The carbon making device includes a tran...

Embodiment 3

[0103] The difference between this embodiment and the above embodiment is that the constant temperature carbonization device includes a heater, a controller, a detector, and a power supply; the heater and the detector are all connected to the controller; the power supply can provide multiple A current / voltage to power heaters, controllers, detectors. The heater is an electric heater, and the detector is a temperature sensor, especially a thermocouple temperature sensor. The electric heater is heated, and the thermocouple temperature sensor detects the real-time temperature of the carbonization device. When the real-time temperature does not reach the preset threshold value of the controller, the controller controls the electric heater to keep heating, and the temperature continues to rise; When the thermocouple temperature sensor detects that the real-time temperature of the carbonization device reaches the preset threshold value of the controller, the heater reduces the heati...

Abstract

The invention discloses a carbon preparation process based on constant-temperature carbonization. The process includes the following steps: S1, crushing a material; S2, performing feeding; S3, performing drying; S4, performing intermediate feeding; S5, performing carbonization; and S6, discharging carbon. The process uses the constant-temperature carbonization manner to prepare the carbon, and carbonization of wood in a carbonization device does not use open-flame carbonization; and combustible gas is generated when the wood in the carbonization device is carbonized, the combustible gas returns to a combustion system through a pipeline for combustion, the combustion system can supply heat to a drying device and the carbonization device through a pipeline, so that an energy recycling systemis formed.

Description

technical field [0001] The invention belongs to the technical field of charcoal preparation, and in particular relates to a charcoal production process of a constant temperature carbonization method. Background technique [0002] Activated carbon has the advantages of good chemical stability and large specific surface area, and has a wide range of applications in the fields of adsorption, separation, and catalysis. China is the first country in the world to produce charcoal. It adopts indigenous methods to produce charcoal, but there are generally the following problems: first, the output of indigenous charcoal is low, the quality is not easy to guarantee, and it occupies a large area; secondly, it pollutes the environment, causing air pollution, and Labor intensity is high. [0003] At this stage, the preparation of activated carbon is mainly made by chemical activation of coal, but due to the non-renewability of coal and the pollution caused by the chemical activation pro...
