[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] Example 1
[0022] Reference Figure 1-4A fluidized bed furnace air inlet preheating structure for producing desulfurized gypsum powder, comprising a Roots blower 1, a conveying pipe 1 2 is provided in the middle position on the right side of the Roots blower 1, a conveying pipe 2 3 is provided on the right side of the conveying pipe 1 2, a cooler 4 is provided on the right side of the conveying pipe 2 3, a connecting pipe 5 is fixedly connected to the right side of the cooler 4, and the number of the connecting pipes 5 is two, a fluidized bed furnace body 6 is provided on the right side of the connecting pipe 5, a sealing ring 1 7 is fixedly connected to the right side of the conveying pipe 1 2, and a sealing ring 1 is fixedly connected to the left side of the conveying pipe 2 3. Sealing ring 2 8, a load-bearing frame 9 is fixedly connected to the right side of the lower surface of the Roots blower 1, and a support frame 10 is fixedly connected to the lower surface of the load-bearing frame 9. A protective sleeve 11 is sleeved on the outer surface of the cooler 4, and an L-shaped frame 12 is fixedly connected to the middle position of the front and rear sides of the protective sleeve 11. An extension plate 13 is fixedly connected to the lower surface of the L-shaped frame 12. There are two extension plates 13. An insulation layer 14 is provided in the middle position inside the protective sleeve 11, and square friction pads 15 are fixedly connected around the inner wall of the protective sleeve 11.
[0023] In the existing technology, when the operator heats the boiling furnace body 6 used for the production of desulfurized gypsum powder, it is difficult to achieve the purpose of preheating the fluidized gas in the furnace. During operation, the heat energy loss of the boiling furnace will be greatly increased, resulting in waste of heat energy. Since the air blown into the boiling furnace is at room temperature, about 25°C, and its calcination temperature is about 175°C, the room temperature air will consume part of the heat energy, resulting in waste of heat energy, which greatly limits the use of the boiling furnace, increases the production cost, and may reduce the quality of the calcined products of the boiling furnace, thereby reducing practicality.
[0024] When the operator uses the device to preheat the furnace for desulfurized gypsum powder production, the Roots blower 1 uses a screw pump to pressurize the room temperature air and blow it out. The air is then transported to the tube bundle of the cooler 4 through a pipeline. The air completes heat exchange in the cooler 4 and the temperature rises to 80-100℃. The air is then introduced into the bellows of the boiling furnace body 6.
[0025] The Roots blower 1 introduces room temperature air into the cooler 4 of the downstream equipment of the boiling furnace body 6 through a pipeline. The temperature in the cooler 4 is about 160°C. The air passes through the tube bundle of the cooler 4 for heat exchange. While lowering the temperature of the cooler 4, the room temperature air is heated to 80-100°C. The hot air is then guided out of the cooler 4 and blown into the bellows of the boiling furnace body 6 to achieve the purpose of preheating the fluidizing gas of the boiling furnace, reducing the heat energy loss of the boiling furnace body 6, reducing the production cost, achieving the purpose of preheating the air, and at the same time increasing the calcination effect of the boiling furnace body 6, greatly improving the stability of product quality.
[0026] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
