Embodiment 1

[0047] Such as Figure 1 to Figure 8 Shown is the labyrinth type two-way catalytic combustion heater of Embodiment 1, which includes an outer casing 1, an air intake pipe 2, a heat exchange device 3 and a heating inner core 4, wherein the heating inner core 4 includes an inner casing 4.1 for The first combustion-supporting catalytic body 4.3 and the second catalytic body 4.4 that the gas plays a combustion-supporting or catalytic role.

[0048] The outer casing 1 is cylindrical, with a gas buffer cavity 1.4 inside, and an exhaust port 1.3 communicating with the gas buffer cavity 1.4 at the upper end. The outer casing 1 includes an upper casing 1.1 and a lower casing 1.2, and the upper casing 1.1 and the lower casing 1.2 are connected by a threaded seal, and the internal parts of the labyrinth bidirectional catalytic combustion heater can be maintained by disassembling the upper casing 1.1 .

[0049] The air intake pipe 2 penetrates into the gas buffer chamber 1.4 from the lo...

Embodiment 2

[0061] The difference between the labyrinth bidirectional catalytic combustion heater of the second embodiment and the labyrinth bidirectional catalytic combustion heater of the first embodiment lies in the heat exchange device 3 .

[0062] Such as Figure 9 As shown, the heat exchange device 3 of Embodiment 2 includes several vertical pipes 3.4 extending along the axial direction of the intake pipe, the vertical pipes 3.4 are arranged in the circumferential direction, and the vertical pipes 3.4 are interlaced to form a gas-liquid flow channel, and the gas-liquid flow The two ends of the channel communicate with the inlet liquid pipe 3.1 and the air outlet liquid pipe 3.2 respectively. The gas or liquid flow entering the heat exchange device 2 will move back and forth along the axial direction of the intake pipe.

Embodiment 3

[0064] The difference between the labyrinth bidirectional catalytic combustion heater in the third embodiment and the labyrinth bidirectional catalytic combustion heater in the first embodiment also lies in the heat exchange device 3 .

[0065] Such as Figure 10 and Figure 11 As shown, the heat exchange device of Embodiment 3 includes an outer tube wall 3.5 and an inner tube wall 3.7 located inside the outer tube wall, and a gas-liquid flow space is provided between the outer tube wall 3.5 and the inner tube wall 3.7, The two ends of the gas-liquid flow space are closed by the end ring plate 3.6, and several partitions are arranged in the gas-liquid flow space, and a gas-liquid flow channel is formed by separating the gas-liquid flow channel. The liquid pipe 3.1 communicates with the gas outlet liquid pipe 3.2.

[0066] The specific partition structure of the partition is as follows: the partitions are arranged along the axial direction, and the two sides of the partition ...

Abstract

The invention discloses a labyrinth bidirectional catalytic combustion heater. A gas caching cavity is formed in an outer shell of the heater, and an exhaust port is formed in an end part. A gas inletpipe penetrates into the gas caching cavity, a connecting seat is arranged at the inner end, and a gas branch channel is arranged in the connecting seat; a heat exchange device is fixedly arranged onthe connecting seat and is provided with a gas inlet liquid pipe and a gas outlet liquid pipe stretching out of the outer shell; a heating inner core comprises an inner shell, a first combustion-supporting catalytic body and a second catalytic body; a hot gas outlet is formed in one end of the inner shell; the first combustion-supporting catalytic body and the second combustion-supporting catalytic body are arranged in the inner shell, the first combustion-supporting catalytic body is arranged out of the second combustion-supporting catalytic body in a sleeving manner, and a gas buffer spaceis formed between the first combustion-supporting catalytic body and the inner shell; and the heating inner core is detachably mounted on the connecting seat through a snap joint structure, and the heat exchange device is located in the heat exchange space. The labyrinth bidirectional catalytic combustion heater heats more quickly.

Description

technical field [0001] The invention relates to catalytic combustion technology heating equipment, in particular to a labyrinth bidirectional catalytic combustion heater. Background technique [0002] The fuel heater heats water through the combustion of fuel gas (such as natural gas, liquefied petroleum gas, city gas, biogas, etc.), so that the water temperature meets the requirements of living and heating, and realizes heating and provides hot water for living and bathing. However, in the process of combustion and heating, a series of problems will arise, such as insufficient combustion. Insufficient combustion not only causes a waste of resources and increases the cost of use, but also produces toxic gases such as CO when the gas is not fully burned. Not only pollute the air, but also endanger people's health. [0003] In order to solve a series of problems existing in combustion heating, people have invented catalytic combustion technology (such as biomass particles, me...
