The purpose of this utility model is achieved through the following technical solutions:
A kind of normal-pressure hot-water boiler heat-exchange system, including the Heat Room and the smoke chamber that are arranged at furnace interior, water inlet and outlet it is provided with on the upside of described Heat Room, described smoke chamber is arranged at below Heat Room, it is provided with multiple protrusion in described Heat Room lower end and stretches to the heat exchange fin of described smoke chamber, described heat exchange fin is internal is water flow region, and described heat exchange fin is outside is flow of flue gas region.
Being provided with multi-stage heat exchanger pipeline in described Heat Room, heat exchanging pipes at different levels head and the tail communicate.
Described heat exchange fin is one-level heat exchange, is provided with secondary heat exchange pipeline and three grades of heat exchanging pipes in described Heat Room, and flue gas is turned back after being exported by smoke chamber in entrance secondary heat exchange pipeline, then three grades of heat exchanging pipes of entrance of turning back.
It is provided with the first dividing plate on the upside of the flue gas outfan of described smoke chamber, the flue gas input of described secondary heat exchange pipeline and the flue gas outfan of three grades of heat exchanging pipes are separated by described first dividing plate, being provided with second partition on the upside of the flue gas input of described smoke chamber, the flue gas outfan of described secondary heat exchange pipeline is separated by described second partition with the flue gas input of described smoke chamber.
Described first dividing plate and second partition inner filling water.
Advantage of the present utility model with good effect is:
1, one-level heat exchange of the present utility model uses the welded heat exchange fin of U-shaped docking, it is internal is water flow region, outside is flow of flue gas region, this considerably increases heat exchange area, cold water quickly can be heated, with conventional hot water boiler ratio, one-level heat exchanging part heat exchange area is its 5.12 times, and one-level heat exchange efficiency arrives 78.5%.
2, two grades and three grades of heat exchange employing lengthening heat exchanger tubes of the present utility model, as much as possible reclaim heat, make whole efficiency reach 96.4%. and achieve heat energy utilization maximization, economize on resources, simultaneously pollution abatement.
