Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.
Referring to fig. 1, the flue gas waste heat preheating system comprises a preheating pipeline 1, wherein a water inlet of the preheating pipeline 1 is connected with an external water source, a water outlet of the preheating pipeline 1 is connected with a liner of a steam engine, and the preheating pipeline is arranged in a smoke exhaust area of a condenser 2. The utility model discloses during the use, open the steam engine, outside water source enters into through the water inlet that preheats pipeline 1 and preheats in the pipeline 1, preheat pipeline 1 and heated the water that preheats pipeline 1 inside after having absorbed a large amount of flue gas waste heat, the temperature can reach 85 ℃ before getting into the steam engine inner bag, the preheating time that cold water got into the steam engine inner bag that has significantly reduced to guaranteed that the steam source exports constantly, also reduced exhaust gas temperature simultaneously, the heat loss is few, the thermal efficiency has just improved, the thermal efficiency can reach more than 93%.
Further, the exhaust area of the condenser 2 is also provided with a radiating fin 3, the radiating fin 3 is connected with the preheating pipeline 1, the radiating fin 3 can further absorb the temperature of the smoke and transfer the temperature to the preheating pipeline 1, the exhaust temperature is reduced while the heat efficiency is improved, and the exhaust temperature is reduced to 70 ℃, so that the service life of the fan is greatly prolonged.
The preheating pipe 1 is spirally arranged in the condenser 2 in order to increase the surface area of the preheating pipe 1 contacting with the flue gas and improve the preheating effect.
Preferably, the preheating conduit 1 is provided as a copper tube.
The above description is only the preferred embodiment of the present invention; the scope of the present invention is not limited thereto. Any person skilled in the art should also be able to cover the technical scope of the present invention by replacing or changing the technical solution and the improvement concept of the present invention with equivalents and modifications within the technical scope of the present invention.
