Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The drawings and specific embodiments do not limit the scope of protection claimed by the present invention.

[0013] see figure 1 , The gas soot blower of the present invention is provided with an air intake device, a transmission device, a packing sealing device, a soot blowing pipe 9 and a bracket 5 . The transmission device includes a motor 1, a reducer 2, sprockets 31 and 32, and a chain 33. The reducer 2 of the sootblower is a cycloidal pinwheel reducer, which can be various commonly used types in the industry. The present invention adopts the cycloid reducer because its deceleration ratio is relatively large (up to 700-1500).

[0014] The air intake device of the sootblower is provided with a soot remover pipe 6, a soot remover solenoid valve 61 and a soot blowing medium pipe 7, a soot blower medium solenoid valve 71, and the s...

Abstract

The invention provides an air soot blower which comprises a transmission device, an air inlet device, a filler sealing device, a soot blowing pipe and a support, wherein one end of the filler sealing device is connected with the air inlet device, and the other end of the filler sealing device is connected with the soot blowing pipe. The air inlet device comprises a soot blowing medium pipe, a soot blowing medium solenoid valve, a soot removing agent pipe, a soot removing agent pipe solenoid valve and an air inlet pipe, wherein the soot blowing medium pipe and the soot blowing medium solenoid valve form a first air inlet channel, the soot removing agent pipe and the soot removing agent pipe solenoid valve form a second air inlet channel, an air inlet cavity is formed in the air inlet pipe, the soot removing agent pipe is connected with the air inlet pipe through a flange, the soot blowing medium pipe is welded with the soot removing agent pipe, and an included angle formed by axes of the soot blowing medium pipe and the soot removing agent pipe is an acute angle. Compared with the existing air soot blowing structures, the air soot blower is greatly simplified in structure, obviously reduced in manufacture cost and reduced in air leakage points, can effectively remove accumulated soot on a furnace pipe and a heat exchange pipe, keeps heat transfer efficiency on a high level and accordingly reduces fuel consumption.

Description

technical field [0001] The invention relates to a gas soot blower used in tubular heating furnaces in petroleum refining and petrochemical fields. Background technique [0002] With the change of crude oil properties and the increase of sulfur content, the problem of fouling and fouling on the convection section and the heating surface of the preheating section of domestic petrochemical enterprises is becoming more and more serious. Once the heating surface accumulates dust, it will seriously affect the heat transfer effect of the heating surface. In the case of serious ash in the convective area, the heat transfer capacity will be reduced by about 30% to 50%, which will reduce the thermal efficiency of the heating furnace by more than 5%, and the fuel energy consumption of the heating furnace accounts for 30% to 40% of the total energy consumption of the refinery. %, so the dust accumulation in the convection section of the domestic petrochemical heating furnace increases ...
