AI Technical Summary

Technical Problem

The heat exchange zone size of existing heat exchangers is fixed and cannot be dynamically adjusted according to the flue gas flow rate, resulting in uneven heat exchange and easy occurrence of local overheating or undercooling.

Method used

The size of the heat exchange zone inside the heat exchanger shell is adjusted by using a space adjustment component and a magnetic reset assembly, and the sealing ring is adjusted by an electric push rod and an air pump to achieve uniform distribution of flue gas inside the heat exchanger and ensure uniform contact of the heat exchange fins.

Benefits of technology

This achieves uniform distribution of flue gas inside the heat exchanger, reduces local overheating or undercooling, and improves heat exchange efficiency and filter performance.

Abstract

The utility model belongs to the technical field of flue gas purification and waste heat recovery, and particularly relates to a multi-stage filter and heat exchanger combined flue gas treatment structure which comprises a heat exchanger and a multi-stage filter unit, and a gas outlet at the rear end of the heat exchanger is communicated with a gas inlet at the front end of the multi-stage filter unit. The heat exchanger comprises a heat exchanger shell communicated with the multi-stage filter unit, a cooling medium feeding pipe and a cooling medium discharging pipe are arranged on the outer side of the heat exchanger shell, a plurality of heat exchange pipes are fixedly connected between the cooling medium feeding pipe and the cooling medium discharging pipe, a heat exchange area is arranged in the heat exchanger shell, and the heat exchange area is communicated with the multi-stage filter unit. A space adjusting piece matched with the heat exchange area is arranged on the heat exchanger shell. According to the utility model, the plurality of heat exchange fins in the shell of the heat exchanger can be in uniform flue gas contact, heat exchange is more uniform, and the phenomenon of local overheating or supercooling is reduced.
