Fan control system and method based on electronic waste and complicated copper-based solid waste

Abstract

The invention discloses a fan control system and method based on electronic waste and complicated copper-based solid waste. The fan control system comprises a fan, a motor and a controller, wherein anemptying adjustment pipeline is connected to an air discharge pipe of the fan, the emptying adjustment pipeline is provided with a mass flow meter, a temperature measuring unit, a pressure meter andan emptying adjustment valve, the mass flow meter, the temperature measuring unit and the pressure meter are used for converting non-standard-condition flow into standard-condition flow, the motor isconnected with the fan and used for providing power for operation of the fan, the controller is connected with the temperature adjusting unit and the emptying adjustment valve and used for adjusting the temperature of the emptying adjustment pipeline through the temperature adjusting unit and linearly adjusting the emptying ratio through the emptying adjustment valve. The fan control system and method have the following advantages that the air volume needed by smelting with the electronic waste, the complicated copper-based solid waste and the like as raw materials can be effectively achieved,replacing the fan is not needed, so that investment of an enterprise is saved, the transformation period is shortened, normal production operation is guaranteed, and energy conservation and consumption reduction are achieved.

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. [0003] There are two major problems in the existing fan air volume adjustment mode: first,...

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 adjus...
