Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon production, in particular to a coal-based activated carbon production device. Background Art

[0002] Coal-based activated carbon is developed through a series of processes including carbonization, cooling, activation, and washing. Its appearance is generally black cylindrical activated carbon. Amorphous coal-based granular activated carbon is also called crushed carbon, and cylindrical activated carbon is also called columnar carbon. It is generally made of powdered raw materials and binders through mixing, extrusion molding, and then carbonization and activation. In its production and preparation process, activation is one of the important processes. Under high temperature, steam contacts carbon to produce an oxidation-reduction reaction for activation, generating carbon monoxide, carbon dioxide, hydrogen and other hydrocarbon gases. The purpose of creating pores in the carbon particles is achieved through the gasification reaction of carbon. The steam activation furnace is an important equipment in the activation process.

[0003] The existing steam activation furnace has the following disadvantages during use: the existing steam activation furnace is generally an ordinary rotating drum structure, and the activated carbon raw materials continuously react with high-temperature steam during transportation inside the activation furnace. This reaction process is generally time-consuming, so the length of the activation furnace generally needs to be very long to meet the activation requirements of coal-based activated carbon, which occupies a large space and has low processing efficiency. For this reason, we propose a coal-based activated carbon production device. Utility Model Content

[0007] Furthermore, it also includes an opening and closing mechanism, an opening and closing mechanism is provided at the connection between the activation furnace and the pressurized pipe, the opening and closing mechanism includes a slot, a spring and a baffle, a slot is horizontally opened in the activation furnace near the end of the pressurized pipe, a spring is installed in the slot and is movably connected to a baffle located inside the pressurized pipe, the baffle is aligned with the middle position of the activation furnace; a slot and a baffle structure are provided at the connection between the end of the activation furnace and the end of the pressurized pipe, a spring structure connected to the baffle is installed in the slot, and under normal use, the spring force pushes the pressurized pipe toward the pressurized pipe. The baffle is pushed up from inside the tube, so that there is a certain distance between the baffle and the middle section of the activation furnace. The material can be normally input into the pressurized tube and discharged. When high-temperature and high-pressure steam is input into the pressurized tube, the high-pressure steam that enters instantly pushes the baffle to both sides. The compression spring makes the baffle fit to the end position of the activation furnace, which plays a certain sealing role, thereby forming a temporary nearly closed environment inside the pressurized tube during the injection of high-pressure steam, thereby improving the pressurization effect. After the pressurization is completed, the spring resets the baffle, so that the steam is discharged from both sides into the activation furnace, thereby improving the quality of activated carbon treatment.

During the activation process, the opening and closing of the steam solenoid valve is regularly controlled according to the material transportation rate. When the steam solenoid valve is opened, high-pressure steam quickly enters the pressure chamber inside the pressure tube from the high-pressure steam pipe, forming an instantaneous high-pressure environment, accelerating the activation reaction of steam and activated carbon, and the activated carbon is continuously discharged after the pressurized treatment, and new activated carbon is continuously input and undergoes a high-pressure reaction, and this cycle is repeated through the high-pressure reaction structure.

In this state, the elastic force of the spring 302 pushes the baffle 304 toward the inside of the pressurized tube 206, so that there is a certain distance between the baffle 304 and the middle section of the activation furnace 1. The material can be normally input into the pressurized tube 206 and discharged. When high-temperature and high-pressure steam is input into the pressurized tube 206, the high-pressure steam that enters instantly pushes the baffle 304 to the two sides, and the compression spring 302 makes the baffle 304 fit to the end position of the activation furnace 1, which plays a certain sealing role, thereby forming a temporary nearly closed environment inside the pressurized tube 206 during the injection of high-pressure steam, thereby improving the pressurization effect. After the pressurization is completed, the spring 302 resets the baffle 304, so that the steam is discharged from both sides to the inside of the activation furnace 1, thereby improving the quality of activated carbon treatment.

[0021] It should be noted that the present invention is a coal-based activated carbon production device. During operation, the coal-based activated carbon to be processed continuously enters the activation furnace 1 under the action of the feeding equipment, and steam is injected into the end of the activation furnace 1 at the same time, so that the activated carbon is fully in contact with the steam during the transportation process inside the activation furnace 1 and undergoes an activation reaction.

When high-temperature and high-pressure steam is input into the pressure pipe 206, the high-pressure steam that enters instantly pushes the baffle 304 to the two sides, compressing the spring 302 so that the baffle 304 fits into the end position of the activation furnace 1, playing a certain sealing role, thereby forming a temporary nearly closed environment inside the pressure pipe 206 during the high-pressure steam injection process, thereby improving the pressurization effect.
