Description

Technical Field

[0001] This utility model relates to the field of dust removal fan technology, and in particular to a dust removal fan device for electric furnaces. Background Technology

[0002] In modern industrial production, electric furnaces, as important thermal energy equipment, are widely used in industries such as steel, non-ferrous metals, and chemicals. However, electric furnaces generate large amounts of dust and harmful gases during operation. If these pollutants are not effectively treated, they will be directly emitted into the environment, seriously affecting air quality and endangering human health. Therefore, the importance of dust removal for electric furnaces is self-evident.

[0003] Existing electric furnace dust removal fans use a fixed power to rotate the fan, thereby purifying the dust generated inside the electric furnace before discharging it. Since the fan speed and power cannot be adjusted automatically according to the electric furnace, it may not be able to guarantee maximum dust removal, and it also increases energy waste. Utility Model Content

[0005] This utility model is achieved using the following technical solution: an electric furnace dust removal fan device, comprising an electric furnace, with a pipe connected inside the electric furnace, a temperature sensor fixedly connected to the outer wall of the pipe, a spray tower connected to the end of the pipe away from the electric furnace, a first pipe connected inside the spray tower, a shell connected to the end of the first pipe away from the spray tower, a second pipe connected inside the shell, a smoke outlet pipe connected to the end of the second pipe away from the shell, a fixed rod rotatably connected inside the shell, fan blades fixedly connected to the outer wall of the fixed rod, a motor fixedly connected to the outer end of the fixed rod, a support plate fixedly connected to the outer wall of the motor, a PLC control cabinet fixedly connected to the outer wall of the support plate, and a frequency converter fixedly connected to the outer wall of the PLC control cabinet.

[0006] Through the above technical solution, the dust and flue gas generated during the operation of the electric furnace enter the interior of the spray tower through pipes. Temperature sensors are fixed to the outer wall of the pipes to monitor the temperature inside the furnace. As the flue gas passes through the spray tower, the dust inside comes into contact with water and is adsorbed. The cooled gas enters the outer casing through pipe one. A motor drives the fan blades to rotate via a fixed rod. When the fan blades rotate, the gas is transported through pipe two to the exhaust pipe, where the purified gas is discharged into the air. The PLC control cabinet can flexibly adjust the motor speed and power based on the temperature sensor readings, thereby maximizing the dust removal effect, reducing energy waste, improving dust removal efficiency, and lowering energy consumption and labor costs. Furthermore, the frequency converter can handle flue gas of different flow rates, saving energy in the process.

[0007] As a further improvement to the above solution, a support block is fixedly connected to the end of the smoke outlet pipe away from the second pipe, and a smoke exhaust hood is fixedly connected to the end of the support block away from the smoke outlet pipe.

[0008] The above technical solution involves fixing a support block at the top of the smoke outlet pipe. The support block is fixed to the smoke exhaust hood, which prevents rainwater and other substances from entering the smoke outlet pipe, thereby ensuring the normal operation of the equipment as a whole.

[0009] As a further improvement to the above solution, a water inlet pipe is connected inside the spray tower, and a water pump is connected to the end of the water inlet pipe away from the spray tower, and a water pipe is connected to the end of the water pump away from the water inlet pipe.

[0010] As a further improvement to the above solution, a filter box is connected to the end of the water pipe away from the water pump, and a support plate is fixedly connected to the outer wall of the end of the filter box near the water pipe.

[0011] As a further improvement to the above solution, the support plate is fixedly connected to the outer wall of the water pump, and the end of the filter box away from the support plate is connected to an outlet pipe.

[0012] As a further improvement to the above solution, the end of the water outlet pipe away from the filter box is connected to the inside of the spray tower. The inner wall of the filter box is provided with a sliding groove, and a slider is slidably connected to the outer wall of the sliding groove. A filter plate is fixedly connected to the outer wall of the slider.

[0013] As a further improvement to the above solution, a handle is fixedly connected to the top of the filter plate, a screw is threadedly connected inside the filter box, and a top cover is threadedly connected to the screw.

[0014] Through the above technical solution, the wastewater inside the spray tower enters the filter box through the outlet pipe, and the water is filtered by the filter plate. At this time, the water pump pumps the filtered water through the inlet pipe back into the spray tower, thereby completing the reuse of resources, avoiding the waste of water resources, reducing production costs, and realizing the concept of green environmental protection.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a system where dust and flue gas generated during the operation of an electric furnace enter a spray tower through a pipe. A temperature sensor is fixed to the outer wall of the pipe to monitor the temperature inside the furnace. As the flue gas passes through the spray tower, dust inside the gas comes into contact with water and is adsorbed. The cooled gas then enters the outer casing through pipe one. A motor drives a fan blade via a fixed rod. When the fan blade rotates, the gas is transported through pipe two to the exhaust pipe, where it is discharged into the air. A PLC control cabinet allows for flexible adjustment of the motor's speed and power based on the temperature sensor readings, maximizing dust removal efficiency, reducing energy waste, improving dust removal efficiency, and lowering energy and labor costs. Furthermore, the frequency converter can handle flue gas flow rates, further saving energy.

[0017] This invention utilizes a system where wastewater from inside a spray tower enters a filter box through an outlet pipe. The water is then filtered by a filter plate. A water pump then pumps the filtered water back into the spray tower through an inlet pipe, thus achieving resource reuse, avoiding water waste, reducing production costs, and realizing the concept of green environmental protection.
