Embodiment Construction
[0010] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.
[0011] Such as figure 1 As shown in the self-cleaning low-temperature flue gas heat exchanger device, the low-temperature flue gas of ≤350°C enters through the inlet 1 and travels outside the coiled pipe, while the refrigerant water enters through the water inlet 2, and the flue gas exchanges heat with the refrigerant water. The water is sent out through the outlet 2, and the cooled flue gas is released through the outlet. The coils are held in place by brackets.
[0012] Such as figure 1 As shown, the coil 3 can be a light pipe or can surround fins to increase the contact area, and the surface of the light pipe or the fins is coated with polytetrafluoroethylene material.
[0013] According to the characteristics of PTFE material, such as strong acid and alkali corrosion resistance, high and low temperature resistance, smooth and non-adhesive surface,...
