Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and specifically discloses a gas heat exchanger. Background Technology

[0002] Gas heat exchangers are energy-saving devices that facilitate heat transfer between two or more gases at different temperatures. They transfer heat from a higher-temperature gas to a lower-temperature gas, bringing the gas temperature to the specified parameters to meet process requirements. Gas heat exchangers are also a key component in recovering and utilizing waste heat from high-temperature industrial flue gas and exhaust gases, thereby improving energy efficiency.

[0003] In existing gas heat exchangers, gas enters the heat exchange chamber directly through the inlet. Due to the high gas velocity, the gas stays in the heat exchange chamber for a short time, resulting in insufficient heat exchange between the gases. Therefore, a gas heat exchanger is needed to solve this problem. Utility Model Content

[0004] This invention proposes a gas heat exchanger that achieves heat exchange through multiple cold gas chambers and multiple hot gas chambers distributed alternately, resulting in high heat exchange efficiency. By setting baffles in the gas chambers, the residence time of the gas in the gas chambers is extended, achieving a full heat exchange effect.

[0005] This utility model is implemented as follows: a gas heat exchanger includes a housing, and a plurality of first partitions are fixedly connected inside the housing. The plurality of first partitions divide the interior of the housing into a plurality of cold air chambers and a plurality of hot air chambers. The plurality of cold air chambers and the plurality of hot air chambers are distributed alternately. A first connecting pipe is connected between two adjacent cold air chambers, and a second connecting pipe is connected between two adjacent hot air chambers.

[0006] The interiors of the multiple cold air chambers and the multiple hot air chambers are all fixedly connected with multiple staggered second partitions.

[0007] To facilitate the introduction of cold air into the cold air chamber, as a preferred embodiment of the gas heat exchanger of this utility model, the outer wall of the housing is provided with a cold air inlet pipe, which is connected to the cold air chamber, and the outer wall of the housing is provided with a cold air outlet pipe, which is connected to the cold air chamber.

[0008] To facilitate the introduction of hot air into the hot air chamber, in a preferred embodiment of the gas heat exchanger of this utility model, a hot air inlet pipe is provided on the outer wall of the housing, which is connected to the hot air chamber, and a hot air outlet pipe is provided on the outer wall of the housing, which is also connected to the hot air chamber.

[0009] To facilitate heat preservation of the casing, the casing of this gas heat exchanger is preferably made of heat-insulating material.

[0010] To improve heat exchange efficiency, the first partition plate is preferably made of copper, which is a preferred material for a gas heat exchanger according to this utility model.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This type of gas heat exchanger introduces cold air into the housing through a cold air inlet pipe. The cold air passes through multiple cold air chambers in sequence and exits the housing through a cold air outlet pipe. Conversely, hot air is introduced into the housing through a hot air inlet pipe. The hot air passes through multiple hot air chambers in sequence and exits the housing through a hot air outlet pipe. The multiple cold air chambers and multiple hot air chambers are staggered, increasing the heat exchange area and resulting in high heat exchange efficiency. Both the cold air chambers and hot air chambers are equipped with staggered second baffles, which increases the residence time of the gas in the chambers, achieving a more thorough heat exchange effect.
