[0033] Example 1: A novel volute cyclone heat exchange assembly, see Figures 1 to 4 , including a cylinder 1, a volute air duct 2, a feed channel 3, an air inlet nozzle 4, a heat exchange component 5 and a flange 6;

[0034] The volute air duct 2 is fixedly arranged at the top of the cylinder 1; wherein, the air outlet end of the volute air duct 2 is communicated with the inner cavity of the cylinder 1; the feed channel 3 is fixedly arranged at the top of the volute air duct 2; wherein, the feed channel 3 is communicated with the inner cavity of the cylinder 1; the air outlet end of the air inlet nozzle 4 is fixedly arranged at the air inlet end of the volute air duct 2; the heat exchange component 5 is arranged at the air inlet end of the air inlet nozzle 4; the flange 6 is arranged at the air inlet end of the heat exchange component 5; the flange 6 is connected to the high-temperature exhaust gas input channel.

[0035] The utility model has the advantages of first recovering part of the heat of the introduced high-temperature exhaust gas by arranging the heat exchange component 5 and the flange 6, reducing the heat contained in the exhaust gas entering the cylinder 1, and preheating the cement raw materials without wasting too much heat. It solves the problem that the cement raw materials passing through the cyclone absorb limited heat of the high-temperature exhaust gas, resulting in most of the heat of the high-temperature exhaust gas being wasted.

[0036] Specifically, the heat exchange assembly 5 includes a wind tube 501, a spiral channel 502, an outlet pipe 503 and an inlet pipe 504;

[0037] The air outlet port of the air duct 501 is connected to the air inlet end of the air inlet nozzle 4, and the air inlet port is connected to the flange 6; the spiral channel 502 is fixed in the inner cavity of the air duct 501; the outlet pipe 503 is fixed at one end of the spiral channel 502; the inlet pipe 504 is fixed at the other end of the spiral channel 502; wherein the outlet pipe 503 and the inlet pipe 504 are respectively connected to the inner cavity of the spiral channel 502; wherein the outlet pipe 503 and the inlet pipe 504 are respectively passed through the air duct 501, the outlet pipe 503 is connected to the discharge pipeline of the hot water exchange, and the inlet pipe 504 is connected to the inlet pipeline of the hot water exchange.

[0038] The utility model has the advantage of providing the wind tube 501, the spiral channel 502, the outlet pipe 503 and the inlet pipe 504, so that the contact area between the spiral channel 502 and the exhaust gas passing through the wind tube 501 is larger, thereby enhancing the heat exchange effect with the exhaust gas.

[0039] Furthermore, the spiral channel 502 adopts a triangular structure design, and the inner and outer sides of the spiral channel 502 are inclined inward; the triangular structure of the spiral channel 502 has little obstruction to the exhaust gas entering, does not affect the circulation of the exhaust gas, and allows the exhaust gas to enter in a spiral shape.

[0040] Furthermore, the spiral channel 502 is made of thermally conductive ceramic material. The spiral channel 502 made of thermally conductive ceramic material is lighter and has better thermal conductivity.
