Boiler chimney capable of preventing smoke exhaust efficiency from being affected by scaling

Abstract

The invention relates to the related technical field of boiler accessories, and discloses a boiler chimney capable of preventing scaling from affecting smoke exhaust efficiency, the boiler chimney comprises a chimney body, a protective exhaust ring is installed on the inner wall of the chimney body, smoke exhaust holes are formed in the protective exhaust ring in an array mode, the smoke exhaust holes are communicated with a control valve pipe, the control valve pipe is provided with an exhaust port, and the exhaust port is communicated with the chimney body. The chimney body is provided with a top end protection device, the top end protection device comprises a mounting side shell, and the mounting side shell is detachably provided with a carrying top shell; according to the boiler chimney capable of avoiding the influence of scaling on the smoke exhaust efficiency, through the arrangement of the top end protection device, the detachable carrying top shell and the mounting side shell form a top end protection shell with the rainwater shielding and protecting effect on the chimney opening end, and the barrel wall treatment device is carried in the carrying top shell; the cylinder wall processing device is used for being matched with the internal structure of the chimney to effectively clean the inner wall of the chimney.

Description

technical field [0001] The invention relates to the related technical field of boiler accessories, in particular to a boiler chimney that prevents fouling from affecting the smoke exhaust efficiency. Background technique [0002] Boiler is a kind of energy conversion of combustion heat, which is mostly used for heat transfer or industrial energy. Boiler chimney is one of the very important components of boiler. It determines whether the boiler can be used normally and safely. The flue gas contains a large amount of carbon, sulfur and other elements, so it will cause scaling on the inner wall of the chimney during the long-term discharge process, and the maintenance of the chimney is very heavy, so the maintenance frequency of most chimneys is low. The scale on the inner wall will affect the discharge of flue gas and the safety of the boiler and other related issues. Contents of the invention [0003] The object of the present invention is to provide a boiler chimney that ...
