Description

Technical Field

[0001] The invention relates to the field of activation furnace temperature control, in particular to an activation furnace temperature precision control system. Background Art

[0002] Activated carbon is a specially treated type of carbon. To produce or regenerate activated carbon, the raw materials are heated in an airless atmosphere to reduce non-carbon components. Gas reactions then erode the surface of the activated carbon, creating a well-developed microporous structure. The micropores on the surface of activated carbon, mostly ranging from 2 to 50 nanometers, give even a small amount of activated carbon a significant surface area.

[0003] During the activated carbon carbonization process, extremely high precision is required for temperature control. If the temperature inside the activated carbon regeneration furnace is too low, the product will be unqualified; if the temperature inside the activated carbon regeneration furnace is too high, a large amount of activated carbon and cloth bags will be burned, which will directly cause the system to be shut down for a long time for maintenance, resulting in economic losses.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] The purpose of the present invention is to provide an activation furnace temperature control system that can achieve precise temperature control of an activated carbon production device.

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Figure 1 This is a schematic diagram of the activation furnace temperature control system of the present invention. Figure 1As shown, an activation furnace temperature control system is applied to an activation furnace system, the activation furnace system including: an activation furnace, a flap valve, a spiral and a burner, the activation furnace temperature control system including: an activation furnace main motor 3, a spiral main motor 6, a flap valve main motor 7 and a wireless temperature measuring element, the activation furnace main motor 3 is connected to the activation furnace, the spiral main motor 6 is connected to the spiral, the flap valve main motor 7 is connected to the flap valve, and the wireless temperature measuring element is arranged inside the activation furnace. The present invention can control the material feed rate by adjusting the speed of the spiral main motor 6 and the flap valve main motor 7. The present invention can control the processing capacity of the activation furnace equipment through the activation furnace main motor 3.

[0020] The activation furnace temperature control system also includes an exhaust gas temperature measuring element 2, which is disposed outside the activation furnace at the exhaust gas discharge location. The wireless temperature measuring elements include a first wireless temperature measuring element and a second wireless temperature measuring element, both disposed within the activation furnace. The activation furnace temperature control system of the present invention utilizes the first and second wireless temperature measuring elements as primary control parameters, with the exhaust gas temperature measuring element 2 as a secondary control parameter.

[0021] The activation furnace temperature control system also includes a natural gas automatic control valve 4 and a combustion air automatic control valve 5, both of which are connected to the burner. The activation furnace temperature control system can control the process temperature in the activation furnace through the natural gas automatic control valve 4 and the combustion air automatic control valve 5.

[0022] The activation furnace temperature control system also includes a controller 1, which is connected to the activation furnace main motor 3, the natural gas automatic control valve 4, the combustion air automatic control valve 5, the screw main motor 6, and the flap valve main motor 7. In a preferred embodiment, during operation, material enters the activation furnace through the flap valve and feed screw. A burner is installed in the activation furnace feed box, generating high temperatures, allowing the material to complete the carbonization process under these conditions. A first wireless temperature measuring element and a second wireless temperature measuring element are installed within the activation section of the activation furnace. These wireless temperature measuring elements rotate with the activation furnace, ensuring direct contact with the material at all times. A temperature measuring element is installed at the tail end of the activation furnace to measure the exhaust gas temperature. The speeds of the activation furnace main motor 3, the screw main motor 6, and the flap valve main motor 7 can all be adjusted via the controller 1. The openings of the natural gas automatic control valve 4 and the combustion air automatic control valve 5 can also be adjusted via the controller 1. When the first and second wireless temperature measuring elements detect low temperatures, controller 1 controls the main motor 6 and flap valve motor 7 to reduce the speed and feed rate. When the first and second wireless temperature measuring elements detect excessively high temperatures, they increase the feed rate and burner power. This entire process is automatically controlled by controller 1. Furthermore, because the first and second wireless temperature measuring elements are in direct contact with the material, the system's temperature control accuracy is highly precise. Fine-tuning the speed of the activation furnace's main motor 3, using the exhaust gas temperature measuring element 2, maintains the entire system at optimal operating conditions.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
