Description

Technical Field

[0001] This utility model relates to the field of special equipment testing technology, specifically to a boiler flue gas collection device. Background Technology

[0002] Industrial boilers produce flue gas during combustion and heating. This flue gas contains many harmful components. During the emission process, it is necessary to monitor the flue gas concentration, emission volume, and harmful components. This monitoring method can help monitor the emission status of the flue gas and prevent malfunctions such as incomplete treatment and flue gas leakage.

[0003] For example, Chinese patent CN214952456U discloses a sulfur trioxide collection device and system for boiler flue gas. The sulfur trioxide collection device includes a shell, a heating chamber, a refrigerated and insulated chamber, a first cover plate, and a second cover plate. The heating chamber and the refrigerated and insulated chamber are disposed within the shell, and the first cover plate is fastened to the opening of the heating chamber. It is based on controlled condensation to collect sulfur trioxide from boiler flue gas. However, for flue gas inside a chimney, the concentration of flue gas changes dynamically during its generation and ascent. The composition of flue gas at different locations may differ significantly. If flue gas is collected only at a fixed location, it may not fully reflect the actual situation of the boiler emissions, resulting in inaccurate flue gas concentration and composition, thus affecting the collection effect.
