Embodiment Construction

[0019] see figure 1 , figure 2 and image 3 , The soot blower of the present invention is provided with an air intake system, a transmission system, a soot blowing pipe 93 and a support 5 . The transmission system includes a motor 1, a reducer 2, and a chain transmission device. The chain drive is made up of driving sprocket 31 , driven sprocket 32 ​​and chain 33 . The driving sprocket 31 is connected with the output shaft of the speed reducer 2, and the driven sprocket 32 ​​is connected with the soot blowing pipe 93, both of which can be connected by means of a flat key connection; the driven sprocket 32 ​​can also be welded on the soot blowing pipe 93. The diameter of the driven sprocket 32 ​​is generally larger than that of the driving sprocket 31 . The speed reducer 2 of the soot blower is a cycloidal pin wheel speed reducer, which can be of various commonly used types in the industry. The present invention adopts the cycloid reducer because its deceleration ratio is...

Abstract

The invention discloses a soot blower. The invention aims to solve the problem that the existing soot blower and soot remover spray system can not well clean adhesive soot deposited on furnace tubes in a convection section of a tube heating furnace and heat exchange tubes in an air preheater. The soot blower of the invention is provided with an air intake system, a transmission system, a soot blowing tube (93) and a bracket (5), wherein the soot blowing tube is provided with two rows of soot blowing nozzles (94) in the axial direction, and a soot remover spray tube (91) is coaxially arranged in the soot blowing tube; the soot remover spray tube is axially provided with two rows of soot remover nozzles (92), and the upper part of each soot remover nozzle extends out of the wall of the soot blowing tube; each soot remover nozzle row and the corresponding soot blowing nozzle row are in the same row, and the soot blowing nozzles and soot remover nozzles in each row are alternately arranged; and the air inlet section of the soot blowing tube is provided with an air inlet (95). The invention is mainly used in tube heating furnaces in the fields of petroleum refining and petrochemical industry.

Description

technical field [0001] The invention relates to a soot blower, in particular to a soot blower used for cleaning the furnace tube in the convection section of a tubular heating furnace and the soot deposited on the heat exchange tube in the air preheater. Background technique [0002] In the field of petroleum refining and petrochemical industry, with the change of crude oil properties and the increase of sulfur content, the problem of fouling and fouling on the furnace tube in the convection section of the tubular heating furnace and the heat exchange tube in the air preheater is becoming more and more serious , affecting the heat transfer effect. In the case of severe dust accumulation, the heat transfer capacity of the furnace tube and heat exchange tube will be reduced by about 30% to 50%; Refining and petrochemical enterprises account for 30% to 40% of the total energy consumption. How to effectively reduce the dust accumulation on the furnace tube and heat exchange tu...
