JPH11201550A - Exhaust tube heat exchanger - Google Patents

Abstract

PROBLEM TO BE SOLVED: To contribute to an environmental protection of an atmospheric pollution, global warming or the like due to an energy conservation by variously reusing an exhaust heat generated by a combustion for heating or the like by recovering. SOLUTION: The exhaust tube heat exchanger recovers an exhaust heat of a combustor for burning, and comprises a cylindrical can 1 having a water storage amount and a plurality of exhaust heat recovery tubes provided in the can l, thereby recovering a supplied water as a hot water. And, the exchanger further comprises an exhaust heat recovering regulating mechanism by a damper 5, a tray 7 for a condensate, a drain 9 to maintain its efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to:
The present invention relates to a heat exchanger that can recover most of exhaust heat generated by an exhaust stack.

[0002]

2. Description of the Related Art A conventional exhaust heat exchanger is of a low efficiency only by passing a water supply coil through a cylinder.

[0003]

The conventional exhaust heat exchanger has a single coil shape and has a small amount of hot water and a low heat exchange rate. An object of the present invention is to provide an efficient stack heat exchanger having a high heat recovery rate of the heat exchanger.

[0004]

A cylindrical can body is provided with a plurality of exhaust pipes for collecting heat larger than the exhaust pipe, and a water storage amount is secured, and the exhaust heat is cut off and adjusted by a damper to recover without missing. . In addition, a dew condensation water intake device based on the effect of collecting exhaust heat will be provided.

[0005]

The exhaust heat exchanger configured as described above can recover most of the exhaust heat. In addition, since heat exchange efficiency is high, dew condensation occurs, which can be taken out of the dew tray and used as humidifying water.

[0006]

A practical example of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the exhaust tube heat exchanger in which a three-piece body is integrally assembled has a damper (5) set in a damper socket (6) and connected to a can body (1). 7) and a drain (9) are connected to a condensation receiving socket (8) in which water is supplied from a water supply port (3) and water is discharged from a water discharge port (4). .

[0007]

Since the present invention is configured as described above, the following effects can be obtained. Efficient heat recovery can be used for various purposes such as heating. Energy savings can contribute to environmental protection such as global warming of air pollution. With the above effects, the present invention has made it possible to provide a highly efficient stack heat exchanger.

Claims (2)

[Claims] 1. A plurality of exhaust pipes (2) are provided in a can body (1) for collecting heat, water is supplied from a water inlet (3), and exhaust heat is absorbed and collected at a water outlet (4). The heat exchange device that makes up. 2. A can body (1) is integrally provided between a damper socket (6) in which a damper (5) is set, a dew-condensing tray (7), and a dew-condensing socket (8) in which a drainage drain (9) is set. The temperature control by the damper, the condensation tray, and the drainage device.
