Abstract
Description
[Technical field]
[0001] The utility model relates to the technical field of boiler equipment, and more specifically, to a header with detachable and interchangeable interface pipe seats. [Background technology]
[0002] Small and medium-sized steam boilers usually have an economizer (economizer or condenser) at the tail of the boiler, which uses the heat of the low-temperature flue gas in the flue at the tail of the boiler to heat the boiler feed water, thereby increasing the feed water temperature. In this process, the heat in the flue gas is transferred to the flowing working medium (usually water), which reduces the flue gas temperature. Doing so can not only reduce fuel consumption, but also reduce flue gas emissions, thereby improving the environmental performance of the boiler.
[0003] In order to obtain the maximum heat exchange effect, the existing headers are arranged in countercurrent for the feed water and flue gas in the economizer (economizer or condenser) pipes. The header on the flue gas inlet side is the water outlet header, and the header on the flue gas outlet side is the water inlet header. The feed water enters from the lower part of the water inlet header, passes through the pipe row and exchanges heat with the flue gas, and then exits from the upper part of the water outlet header. The inlet and outlet headers are respectively provided with venting and water discharge interfaces. Usually, the economizer is designed with the inlet and outlet headers according to the flue gas flow direction. The inlet and outlet headers are provided with fixed inlet (outlet) water and venting (water) interfaces. If the flue gas flow direction changes, the economizer needs to be redesigned according to the installation position of the inlet and outlet headers or the installation direction of the economizer needs to be adjusted when installing it to meet the requirements of countercurrent heat exchange of feed water and flue gas. Therefore, the conventionally designed economizer has certain limitations. It needs to be specifically designed or arranged in a specific installation orientation according to the flue gas flow direction. When it needs to be replaced, the entire header needs to be replaced, which lacks flexibility and is not conducive to movement and replacement in actual use. [Utility Model Content]

[0018] Working principle:
[0019] The utility model discloses a header with a detachable and interchangeable interface pipe seat function.
