Example Embodiment

[0015] 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.

[0016] figure 1 It is a specific embodiment of the retractable gas soot blower of the present invention, including a bracket system, an air intake system, a transmission system, a limit system and a soot blowing pipe assembly; the transmission system is provided with a motor 4, a reducer 3, and a driving chain Wheel 2, small sprocket 5, chain 6, driven sprocket 7, worm wheel 16, worm screw 17, carriage 12, the speed reducer 3 of described soot blower is cycloidal pin wheel speed reducer, and it can be various in industry A commonly used type. The present invention adopts the cycloid reducer because its deceleration ratio is relatively large (up to 700-1500).

[0017] The drive system driving sprocket 2 of the soot blower is ...

Abstract

The invention provides a telescopic gas soot blower, which comprises a bracket system, a gas inlet system, a transmission system, a limit system and a soot blowing pipe component, wherein a driving chain wheel, a driven chain wheel, a small chain wheel, a chain, a carriage and an external soot blowing pipe of the transmission system form chain transmission; the chain is disconnected, and both ends of the chain are respectively connected with a sidewall board of the carriage; the external soot blowing pipe is arranged on the sidewall boards of the carriage through bearings; the small chain wheel, a worm wheel, a worm and the external soot blowing pipe of the transmission system form worm wheel and worm transmission; a limit switch of the limit system is arranged on a bracket board; a collision block is arranged on one sidewall board of the carriage; the external soot blowing pipe is sleeved on an internal soot blowing pipe; one end of the internal soot blowing pipe extends out of an opening end of the external soot blowing pipe to be connected with a gas inlet pipe; the internal soot blowing pipe is communicated with the external soot blowing pipe and a soot blowing nozzle on the external soot blowing pipe; and a soot blowing pipe sealing mechanism is arranged between the internal soot blowing pipe and the external soot blowing pipe. Because of few transmission parts of the soot blower, the transmission mechanism of the existing soot blower is prevented from being jammed, rusted and damaged during running.

Description

technical field [0001] The invention relates to a retractable 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 ash deposition and scaling on the heating surface of the convection section of the heating furnace in 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 fur...
