Detailed Description
The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.
As shown in fig. 1-2, the utility model provides a heat transfer positive displacement heat exchanger flow equalizes, including jar body 1, set up in the upper cover plate 2 at jar body 1 top, set up in the lower apron 3 of jar body 1 bottom, one side of jar body 1 is provided with hot water return mouth 4, and jar body 1 is located hot water wet return department and is equipped with into water baffle 17. 2 tops of upper cover plate are provided with hot coal import 5, 3 bottoms of lower cover plate are provided with hot coal export 6, one side that upper cover plate 2 is located hot coal import 5 is provided with hot water export 7, one side that lower cover plate 3 is located hot coal export 6 is equipped with drain 8, upper cover plate 2 internal fixation installs upper tube plate 9, fixed mounting has lower tube plate 10 down in the lower cover plate 3, form water storage space between upper tube plate 9 and the lower tube plate 10, a plurality of heat exchange tube 11 has evenly been arranged between upper tube plate 9 and the lower tube plate 10, heat exchange tube 11 can run through whole water storage space, a plurality of heat exchange tube 11 forms draft tube or honeycomb duct between upper tube plate 9 and lower tube plate 10.
An upper header 12 is formed between the upper tube plate 9 and the hot coal inlet 5, and a lower header 13 is formed between the lower tube plate 10 and the hot coal outlet 6.
The tank body 1 is provided with a temperature sensor interface 14, a thermometer interface 15 and a pressure gauge interface 16.
Heated water (hot water return water and tap water) enters from a hot water return port 4 on a tank body 1, is divided by a water inlet baffle plate 17 and then enters a water storage space in the tank body 1, hot coal enters an upper header 12 through a hot coal inlet 5 at the top, flows to a lower header 13 through an upper tube plate 9 and a heat exchange tube 11, flows in the heat exchange tube 11 to form a tube pass, the heat exchange tube 11 heats the heated water, the heated water flows out from a hot water outlet 7 at the top of the tank body 1, no dead water area exists in the tank body 1, and meanwhile, the heat exchange tube 11 can ensure uniform heating.
