Description

Technical Field

[0001] The utility model relates to the technical field of plate-type economizers, in particular to a heat exchange plate spacing fixing and anti-vibration structure for a wide-channel plate-type low-temperature economizer. Background Art

[0002] The economizer used on the flue of a large thermal power plant has a relatively high overall height (generally greater than 3m), which makes the middle length of each heat exchange plate longer (the thickness of the heat exchange plate is generally 6mm), resulting in uneven spacing between adjacent heat exchange plates. At the same time, when the flue gas flows between two adjacent heat exchange plates, it is easy to cause the heat exchange plates to vibrate, causing damage to the economizer as a whole. Therefore, there is an urgent need for a wide-channel plate-type low-temperature economizer with a fixed heat exchange plate spacing and an anti-vibration structure, which can not only effectively balance the spacing between several heat exchange plates on the economizer, but also effectively reduce the vibration of the heat exchange plates caused by flue gas, avoid damage to the economizer by vibration, and extend the service life of the economizer.
