The fan control system includes: a fan, and an air discharge adjustment pipe is connected to the exhaust pipe of the fan. The air discharge adjustment pipe is provided with: Mass flowmeter, temperature measuring unit, pressure gauge, mass flowmeter, temperature measuring unit and pressure gauge are used to convert non-standard condition flow into standard condition flow; vent regulating valve; motor, connected with fan, used to provide power for fan operation power; a controller, connected with the temperature regulating unit and the vent regulating valve, used to adjust the temperature of the vent regulating pipeline through the temperature regulating unit, and linearly adjust the vent ratio through the vent regulating valve. The invention has the following advantages: it can effectively solve the air volume required for smelting with electronic waste and complex copper-based solid waste as raw materials, and does not need to replace the fan, which not only saves the investment of the enterprise, but also shortens the transformation period and ensures the normal operation of production And save energy and reduce consumption.

Description

technical field [0001] The invention relates to the technical field of fan control, in particular to a fan control system and control method based on electronic waste and complex copper-based solid waste. Background technique [0002] With the development of the environmental protection situation and the depletion of mineral resources, the renewable resource industry for processing electronic waste and complex copper-based solid waste is emerging. However, electronic waste and complex copper-based solid waste have more complex components than conventional minerals, and the oxygen content that needs to be provided during the smelting process varies greatly. The process fan provides the oxygen required for smelting furnace smelting, but the raw material composition of the smelting furnace is complex, and the air volume required for different ratios of raw materials is quite different.

Problems solved by technology

Electronic waste and complex copper-based solid waste have more complex components than conventional minerals, and the oxygen content that needs to be provided during the smelting process varies greatly

The process fan provides the oxygen required for smelting furnace smelting, but the raw material composition of the smelting furnace is complex, and the air volume required for different ratios of raw materials is quite different

[0003] There are two major problems in the existing fan air volume adjustment mode: First, the air volume adjustment range is small, which is 70% to 100% of the rated air volume, which cannot meet the changing requirements of the melting furnace

The second is that it takes a long time to adjust the stability. You must first set the air pressure. After the system is stable, you can slowly adjust the air volume until the required air volume

Because this constant pressure adjustment control mode does not match the requirements of the smelting process program mode, and since the two parameters of air volume and air pressure are automatically adjusted stably, in actual operation, the two adjustments interfere with each other, resulting in large fluctuations in fan operation, and even frequent stop, start

Therefore, the original fan air volume adjustment mode not only cannot meet the production process requirements, but also brings great operational safety hazards to the operation of the melting furnace and the fan.
