Embodiment Construction

[0025] Such as Figure 1-10 As shown, the device is divided into a water heat exchange circuit and a combustion heating circuit.

[0026] The water heat exchange circuit during implementation: under the action of pressure, cold water enters the lower water tank 16 from the water inlet 18, and is disturbed by the spoiler 17. The water with uniform temperature enters the lower water tank 16 from multiple connection ports of the lower water tank 16 respectively. Layer spiral casing 13, water flows in the spiral direction in each layer of spiral pipe, and enters the middle water tank 10 through the connection port and is disturbed by the spoiler 11, and the water with uniform temperature enters the upper spiral through the multiple connection ports of the middle water tank 10. Casing 6. Water flows in the spiral direction in each spiral tube, enters the upper water tank 3 respectively through the connection port, and is disturbed by the spoiler 4, and the water with uniform tempe...

Abstract

The invention relates to a high-efficiency condensing type heat exchanger which comprises a tubular shell, an upper-layer water tank, an upper spiral sleeve pipe, a middle-layer water tank, a lower spiral sleeve pipe, a lower-layer water tank and a U-shaped condensed water collection smoke exhauster. The heat energy generated in the combustion process of water exchange is used for lowering the temperature of the smoke generated in the combustion process, and the water vapor in the smoke is condensed into the liquid state from the gaseous state to generate condensed water, thereby absorbing the latent heat emitted in the condensation process and improving the heat exchange efficiency of the heat exchanger. In the invention, the shell has a dismountable internal structure, can be cleared and maintained easily, improves the heat exchange efficiency of the heat exchanger, is suitable for various products of gas-fired hot water, and is suitable for domestic gas-fired hot water heating equipment and the like.

Description

technical field [0001] The invention belongs to a high-efficiency condensation heat exchanger. Background technique [0002] At present, the manufacturing process of the existing condensing heat exchanger is complicated, the manufacturing cost is high, the cleaning and maintenance are difficult, and the heat exchange efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency condensing heat exchanger, which can exchange the heat energy generated in the combustion process with water, reduce the temperature of the flue gas generated during the combustion process, and condense the water vapor in the flue gas from gaseous state to liquid state. Generate condensed water, thereby absorbing the latent heat released during the condensation process, and improving the heat exchange efficiency of the heat exchanger. [0004] The invention is composed of a tubular casing, an upper water tank, an upper spiral casing, a mid...
