Detailed Description
The following describes a flue gas recirculation combustion control device of a carbon roasting furnace in further detail with reference to the accompanying drawings.
With reference to the attached drawings 1-2, the flue gas recirculation combustion control device for the carbon roasting furnace comprises a variable frequency centrifugal fan 1 and a flue gas inlet pipeline 2 connected with an air inlet of the variable frequency centrifugal fan 1; the flue gas gets into and is equipped with electric butterfly valve 3, flow sensor 4 on the pipeline 2, flow sensor 4 locates between electric butterfly valve 3 and the frequency conversion centrifugal fan 1, flow sensor 4 is located inside the flue gas gets into pipeline 2, 4 electric connection of flow sensor has PLC controller 5, frequency conversion centrifugal fan 1 and 5 electric connection of PLC controller.
When the method is implemented, the flue gas inlet pipeline 2 is connected with a flue gas pipeline of a roasting furnace, the air outlet of the variable-frequency centrifugal fan 1 is connected with a flue hole of a roasting high-temperature chamber of the roasting furnace, the flue gas is pushed to the flue hole of the roasting high-temperature chamber of the roasting furnace under the action of the variable-frequency centrifugal fan 1 through the electric butterfly valve 3, and is combusted secondarily through the roasting high-temperature chamber, wherein the pushing amount of the flue gas is measured by the flow sensor 4 in real time, and the rotating speed of the variable-frequency centrifugal fan 1 is controlled through the PLC 5, so that the pushing amount of the flue gas is automatically.
The invention can effectively control and reduce harmful substances in the waste gas discharged by the industrial furnace, achieves the purposes of recycling and burning the smoke, reducing the content of the harmful substances in the smoke, such as nitrogen oxide, asphalt smoke, sulfur dioxide, oxygen, and the like, saving the consumption of natural gas, improving the burning efficiency, burning the asphalt smoke, improving the homogeneity of products and protecting air, is further beneficial to the health of human bodies, and has the advantages of simple operation, convenient use, stability and reliability.
The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
