[0002] In industrial production, the flue gas produced by various kilns contains a lot of heat energy, but most of this part of waste heat is not fully utilized at present, but is directly discharged into the air along with the flue gas through the flue, resulting in extreme energy consumption. On the other hand, due to the large amount of...

Example Embodiment

[0009] The present invention will be further described below in conjunction with the drawings and specific embodiments.
[0010] Referring to the drawings, the serpentine coil 8 is installed at the flue entrance in the kiln body 7, and several furnace hot air pipes 6 perpendicular to the coil 8 are arranged between the pipes of the coil 8; Both ends of 8 pass through the furnace body 7, one end is connected to the lower circulation pipe 5 installed under the heat preservation water tank 1 through a flange, and the other end is connected to the upper circulation pipe 1 installed above the heat preservation water tank 1 through another flange. 0 is connected. The heat preservation water tank 1 is installed at a position higher than the furnace body 7 through a bracket. A water outlet pipe 3 is installed above the other side of the heat preservation water tank 1 and a water supplement pipe 4 is installed below. In order to ensure that the water in the system can fully circulate and avoid the coil 8 from bursting or being burned through, a water pump 9 is also provided on the upper circulation pipe 10.
[0011] In order to reduce the pressure in the heat preservation water tank 1, an exhaust pipe 2 can be arranged on the top of the heat preservation water tank 1; for ease of use, a water temperature meter 11 is arranged on the heat preservation water tank 1 near the upper circulation pipe 10; for cleaning and Sewage discharge is convenient, and a sewage pipe 12 is also provided at the bottom of the heat preservation water tank 1.
[0012] In order to make full use of the waste heat in the high-temperature flue gas, on the basis of embodiment 1, a heating water tank 13 can be installed on the top of the furnace body 7; another one is installed below the heating water tank 13 to communicate with the bottom of the insulation water tank 1. There is another upper circulating pipe 10 connected to the upper part of the heat preservation water tank 1, and another water pump 9 is provided on the upper circulating pipe 10. In the same way, the bottom of the heating water tank 13 is also provided with a sewage pipe 12; a heating water tank 13 is provided on the top of the furnace body 7. The steam drum is communicated with the input end of the radiator through the pipe, and the output end of the radiator is connected to the condensate water pipe. The water supply pipe and the heat preservation box are connected, the water in the steam drum is vaporized into steam, and the condensed water pipe 17 is connected to the heat preservation box 1 through the water supply pipe 4.
