Abstract
The invention relates to a gas-fired shock wave ash removal device in petroleum refining. In the prior art, gas rich in CO is regenerated and introduced into a furnace to burn in a delay mode by using a CO furnace, vapor is generated by using waste heat at the same time, but due to the fact that fume comprises a great amount of catalyst dust, on the condition that the CO furnace recycles fume heat, a high-temperature superheater tube and an economizer tube deposition are very serious, the existing ash removal device cannot meet requirements, and generally the furnace needs to be stopped for ash removal every two months. The gas-fired shock wave ash removal device in the petroleum refining comprises a shock wave generator, a mixer and an igniter. Air and fuel gas are respectively communicated with the mixer through two air inlet pipelines. The other end of the mixer is connected with the shock wave generator through the igniter. The lower end of the shock wave generator is arranged inside a furnace wall in a penetrating mode through pipelines. A magnetic valve is arranged on the air inlet pipeline of the mixer. The gas-fired shock wave ash removal device in the petroleum refining is wide in range of application, good in ash removal effect and small in maintenance.
Description
Technical field
The present invention relates to the gas shock-wave ash blowing device in a kind of petroleum refining.
Background technology
Catalytic cracking unit is the very important secondary operations device of oil plant, its energy consumption level has significant impact to full factory, and utilize now the CO boiler that the regeneration that device is rich in CO gas is delayed to introduce the stove internal combustion, utilize simultaneously lung heat potential to produce steam, but due in flue gas with a large amount of catalyst dusts, make the CO boiler in the situation that the recovered flue gas heat, hyperthermia and superheating pipe and economizer tube dust stratification are extremely serious, existing soot blower can't meet the demands, and generally needs blowing out deashing about two months.
Summary of the invention
Technical problem solved by the invention be to provide a kind of simple in structure, purge effective, the gas shock-wave ash blowing device in petroleum refining applied widely.
For solving above-mentioned technical problem, the technical scheme that the present invention takes:
Gas shock-wave ash blowing device in a kind of petroleum refining, its special character is: comprise shock wave generator, blender, igniter, air and combustion gas are communicated with blender by two air inlet pipelines respectively, the blender other end is connected with shock wave generator by igniter, and the shock wave generator lower end is located in furnace wall by pipeline; Be provided with magnetic valve on the air inlet pipeline of described blender.
Above-mentioned magnetic valve, blender, igniter are connected with switch board respectively.
Compared with prior art, the present invention is applied widely, purging is effective, maintenance is little.
Description of drawings
Fig. 1 is structural representation of the present invention.
