Problems solved by technology
[0002] At present, regardless of coal-fired furnaces, gas-fired furnaces or oil-fired furnaces, there is a problem of low thermal efficiency. One of the important reasons is the heat loss of exhaust fumes, and the high-temperature flue gas carries harmful gases such as dust and sulfur dioxide, which are discharged to Environmental pollution and increase in atmospheric temperature in the atmosphere
The currently used waste heat recovery device is usually installed between the boiler exhaust port and the chimney outlet. The disadvantage of this method is that the boiler flue gas waste heat device has a large resistance to the flue gas discharged from the boiler, which will have a certain impact on the combustion conditions inside the boiler. It is not easy to maintain and clean the boiler flue gas waste heat recovery device, and it is still necessary to shut down the gas boiler for maintenance and cleaning of the waste heat recovery device. ; In addition, more dust will be mixed in the flue gas, and these dusts will be absorbed in the waste heat recovery device for a long time, which will easily damage the waste heat recovery device

Embodiment Construction
[0011] refer to figure 1 , a flue gas waste heat recovery system, including a boiler 1, a chimney, a vertical flue 2 is arranged between the boiler 1 and the chimney, and a branch pipe 3, the branch pipe 3 is U-shaped, and the U-shaped branch pipe 3 The two ends of the pipe are connected to the flue 2, and the control valve 4 is installed on the flue 2 and the branch pipe 3.
[0012] The branch pipe 3 is connected with a dust settling chamber 5 and a waste heat recovery device 6 in sequence. The dust settling chamber includes a rectangular box, and the waste heat recovery device 6 is spirally connected with each other in the box. Vertically, a dust output pipe 8 is installed at the lower end of the dust settling chamber 5 . The waste heat recovery device 6 includes a cylindrical shell, and a spiral heat exchange tube 9 runs through the cylindrical shell in the radial direction, and the spiral heat exchange tube 9 is sealed and connected with the shell wall of the cylindrical ...

The invention discloses a smoke waste heat recovery system which comprises a boiler, a chimney and a flow distributing branch pipe. A vertical flue is arranged between the boiler and the chimney. The flow distributing branch pipe is U-shaped, and two ends of the U-shaped flow distributing branch pipe are connected on the flue. A dust settling chamber and a waste heat recovery device are sequentially connected on the flow distributing branch pipe, baffling plates staggered mutually are arranged in a smoke settling chamber, a dust output pipe is arranged at the lower end in the dust settling chamber, a heat exchanging pipe penetrates the waste heat recovery device and is connected with the waste heat recovery device in a sealing mode, a condensate outlet is formed in the lower end of the waste heat recovery device, and the heat exchanging pipe is connected with a water pump. By means of the system, recovery of the smoke waste heat can be achieved, smoke can be purified, and dust is prevented from being emitted to the atmosphere.
Description
technical field [0001] The invention belongs to the technical field of heat exchange equipment manufacture and application. Background technique [0002] At present, regardless of coal-fired furnaces, gas-fired furnaces or oil-fired furnaces, there is a problem of low thermal efficiency. One of the important reasons is the heat loss of exhaust fumes, and the high-temperature flue gas carries harmful gases such as dust and sulfur dioxide, which are discharged to In the atmosphere, it causes environmental pollution and increases in atmospheric temperature. The currently used waste heat recovery device is usually installed between the boiler exhaust port and the chimney outlet. The disadvantage of this method is that the boiler flue gas waste heat device has a large resistance to the flue gas discharged from the boiler, which will have a certain impact on the combustion conditions inside the boiler. It is not easy to maintain and clean the boiler flue gas waste heat recover...
