Abstract

The invention relates to a novel non-leakage same step extension steam sootblower, comprising a casing (11), a supporting guide rail (9), a guide and drive rack (10), a synchronous drive device (6), a connection pipe (5), a blowing pipe (7), a steam conduction valve (4), a guide wheel (3), a hose (2) and a hose collection pipe (1). The connection pipe is connected with the outlet of the steam conduction valve (4). The steam inlet of the steam conduction valve is connected with the hose (2). The hose is presented in a spiral shape and is collected in the hose collection pipe (1). The synchronous drive device (6) comprises a motor (6.2), a decelerator (6.3), a cam (6.1), a gear or a sprocket pair (6.4) and a drive gear (6.6). The decelerator has two output ends. One of the output shafts of the decelerator is connected with the cam (6.1) and the gear or the sprocket pair (6.4). The outer edge of the cam is matched with the moving mode of the valve stem system (4.1) of the steam conduction valve (4). The other output shaft is connected with the drive gear (6.4). The drive gear is meshed with the guide and drive rack. If blowing is needed in the process of the blowing pipe extension, the blowing pipe is conducted, and if the blowing is not needed, the blowing pipe is closed. The novel non-leakage same step extension steam sootblower has high reliability and high blowing efficiency without leakage.

Description

technical field [0001] The invention relates to a soot blower, in particular to a novel non-leakage synchronously long telescopic steam soot blower. It is mainly used for steam soot blowing of convection tubes in convection sections of industrial heating furnaces and industrial boilers to improve heat transfer efficiency. The utility model belongs to the high-efficiency and energy-saving technical field of industrial heating furnaces and boilers. Background technique [0002] At present, due to different types of fuel, the ash collection situation and ash collection amount of the convection tube in the convection section of industrial boilers will vary greatly. Ash collection will reduce heat transfer efficiency, increase exhaust gas temperature, and waste energy. Usually, in order to improve the heat transfer efficiency, a steam soot blower is used for soot blowing. The steam soot blower usually used in the convection tube of industrial heating furnace and boiler convecti...
