The utility model discloses a multi-
barrel type simple
chimney and an inner wall anti-
corrosion structure. The multi-
barrel type simple
chimney comprises a concrete outer
barrel, a multi-
pipe type steel inner barrel, a
flue, a steel inner barrel connecting platform, a short-circuit
chimney, a suspension
system, a shake stopping
system, an expansion
system, a lining anti-
corrosion system and a drainage system. The concrete outer cylinder is of a concrete structure, the upper portion is a straight cylinder section, the lower portion is a conical section, and the multi-
pipe type steel inner cylinder is used for supporting and stopping shaking. A short-circuit chimney is pre-buried in the steel inner cylinder connecting platform and is in flexible connection with the multi-
pipe type steel inner cylinders, so that the multi-pipe type steel inner cylinders are connected in parallel. The chimney is divided into an upper part and a lower part, the upper part collects
flue gas and discharges the
flue gas, the lower part is connected with each unit flue and does not interfere with each other, all
flue gas contact surfaces are provided with the lining anti-
corrosion systems, and the anti-corrosion expansion system and the chimney middle platform are sealed. According to the utility model, the problems of mutual interference of
smoke exhaust of multiple units, connection of the outer cylinder and the inner cylinder, overlarge anti-corrosion area and arrangement of the multi-cylinder steel inner cylinder are solved, the
engineering quantity is low, and the device is safe, reliable and low in manufacturing cost.
