Embodiment Construction

[0018] figure 1 It is a flowchart of an automatic control method for activated carbon processing and preparation in a specific embodiment of the present invention. The methods include:

[0019] In step 101, a temperature signal and a flow signal are received. The temperature signal includes the temperature of the carbonization furnace and the temperature of the activation furnace. The temperature is detected by various temperature sensors, which may be thermocouples or other temperature sensing elements.

[0020] Since there are many temperature points of the carbonization furnace and the temperature of the activation furnace to be collected, preferably, in step 102, it is necessary to determine whether the temperatures and flow rates of all detection points have been detected. Detect whether all the temperature signals and flow signals have been received, if the temperature signals of all the temperature detection points have been received, continue to the subsequent proce...

Abstract

The invention discloses an automatic control method and a system for processing and preparing active carbons. The system comprises a temperature detection unit, a flow detection unit, a temperature determination unit, a flow determination unit, an electric valve control unit, a steam valve control unit, an exchange control unit and a discharge control unit. The method and the system have the advantages that randomness of manual control is avoided, a manual control method based on experiences is replaced by a scientific and programmed control method, carbonization and activation conditions during the production process of active carbons are effectively controlled, ignition loss rate is reduced, acquisition rate and quality of the products are improved, and the fluctuation range of product indexes is greatly narrowed.

Description

technical field [0001] The invention relates to the field of activated carbon processing and preparation, in particular to an automatic control method and system for activated carbon processing and preparation. Background technique [0002] At present, in activated carbon enterprises, all operations in the carbonization and activation section, such as activation time, half-furnace switching, temperature adjustment, steam flow, air distribution volume, flue damper and other process control are all done manually with the help of experience. Basically stay at the initial level of the activated carbon industry. [0003] The use of manual control or simple instrument control is random, labor-intensive, low-efficiency, increases labor costs, and the product quality is unstable, fluctuates greatly, and the product loss rate is high, which seriously affects the economic benefits of the enterprise. In addition, manual control also has many potential safety hazards. [0004] Therefo...
