[0002] The development of an enterprise is inseparable from good industrial plants. Industrial plants are often equipped with exhaust chimney structures, which are mainly composed of a flue gas inlet, a chimney air guide body and an air outlet. The exhaust chimney structure is used to discharge the flue gas generated when the industrial plant is working. However, the exhaust chimney structure of the industrial plant still has some defects when it is used specifically.

It is not easy to perform multi-stage diversion and discharge according to the pressure of the flue gas to be discharged, nor is it easy to regulate the flow rate of the final flue gas. This leads to low applicability of the device and poor exhaust effect. Moreover, it generally does not have a heat exchange structure. When the flue gas is hot, it often causes more serious thermal pollution to the external environment and wastes heat energy. Utility Model Content
