Description

Technical Field

[0001] This utility model belongs to the field of fan technology, and in particular relates to an environmentally friendly fan heat recovery and utilization device. Background Technology

[0002] A fan is a mechanical device that uses mechanical energy to drive an impeller to rotate, giving gas (such as air or flue gas) kinetic and pressure energy, thereby achieving gas transport, ventilation, cooling, or process pressurization. With increasing global focus on sustainable development and environmental protection, and increasingly stringent emission standards for pollutants such as industrial waste gas and dust, environmentally friendly fans have become core equipment in industrial production and urban environmental management.

[0003] Existing literature discloses an environmentally friendly fan that can be used to discharge waste in steelmaking in the industrial field. Since the operation of the dust removal fan generates a large amount of high-temperature waste gas, direct discharge will not only pollute the air but also reduce energy efficiency. However, the existing heat recovery devices for fans have low recovery efficiency and some heat is still lost. In order to fully recover and utilize the heat in the gas, designing an environmentally friendly fan heat recovery and utilization device has become an urgent problem to be solved.

The heat inside the exhaust gas is fully recovered and utilized. There are ten sets of water inlet pipes 21 and flow equalizers 26. The ten sets of water inlet pipes 21 and flow equalizers 26 are distributed in a circle on the surface of the heat preservation box 20. The positions of the water inlet pipes 21 and flow equalizers 26 correspond one-to-one. The flow equalizers 26 can control the water in each pipe to flow at a uniform speed. The water in the pipes receives heat more evenly, which is conducive to improving the efficiency of heat recovery. The body, heat recovery components and filter box are connected by exhaust pipe 18. The heat transfer block 22 is made of aluminum. The exhaust pipe 18 can avoid excessive contact between the gas discharged by the fan and the heat recovery components, reduce the blockage of impurities in the gas, and make the heat recovery of the equipment more stable.

[0027] Example 2:

[0028] Please see Figure 5-6 A bracket 11 and a motor 8 are fixed to the surface of the filter box 6. A rotating gear 13 is fixed to the surface of the bracket 11. A bevel gear 3 is fixed to the output end of the motor 8. A bevel gear 12 meshes with the surface of the bevel gear 3. A filter screen 15 is slidably connected inside the filter box 6. The bevel gear 12 and the rotating gear 13 are connected by a synchronous belt 14. The filter box 6 can filter the gas discharged from the fan 2 through the filter screen 15 to reduce air pollution. A toothed block 16 is fixed to the surface of the filter screen 15. A slot 10 is opened on the side of the filter screen 15. A sealing plug 7 is provided on the surface of the filter box 6. The design of the toothed block 16 and the slot 10 can make the filter screen 15 move more smoothly and stably. The sealing plug 7 can reduce the loss of gas in the filter box 6.

[0029] Working principle: When using this device, the user first needs to start the fan 2 to introduce gas from the exhaust pipe 18 into the heat recovery component 4, which will dissipate the high temperature gas in the exhaust pipe 18, thus raising the internal temperature of the entire heat recovery component 4. Next, the flow equalizer 26 is started to transport water from the water tank 5 into the water inlet pipe 21, and then into the water inlet pipe 21. At the same time, the heat accumulated inside the heat recovery component 4 is transferred to the water outside the water inlet pipe 21. The heated water enters the temporary water storage layer 24, and then flows into the insulation box 20. Finally, it is discharged through the drain pipe 9. Since there are many impurities in the gas, it is easy to clog with long-term use, which will also reduce air quality. The sealing plug 7 can be removed, and the motor 8 can be started. The rotation of the bevel gear 3 will drive the rotation of the bevel gear 12 and the rotating gear 13 in sequence, which will eventually drive the filter screen 15 to move left and right, thus cleaning the surface of the filter screen 15. The operation is simple and convenient.
