Description
Technical field
The furnace tube outer wall walking mechanism with guiding and obstacle crossing function that the present invention relates to a kind of, belongs to vehicle chassis technology neck
Domain, in particular to special cylindrical type rail vehicle operation technique range.
Background technique
In many commercial plants in China, such as oil plant, part pyrolysis furnace, heating furnace heating tube in section of convection chamber are by several rows of
Regular and horizontally disposed finned tube or studded tube composition, fin or ailhead can increase the external surface area of boiler tube, be conducive to heat
Transmission improves heat transfer efficiency.In the process of running, the solid particles such as the oil coke in inner flue gas of the stove, powdered carbon, sulfide, minerals
When mutually colliding with heating tube in section of convection chamber outer wall, partial particulate is deposited on the fin surface of furnace tube outer wall under the action of inertia force
Or head surface.Meanwhile the corrosive mediums such as sulfur dioxide in flue gas have certain corrosiveness to boiler tube, corrosion product also holds
Easily it is adhered to furnace tube outer wall.With the extension of stove runing time, the dirt of furnace tube outer wall accumulation is more and more.It is dirty when serious
Dirt all wraps up boiler tube, can not see the fin or ailhead of furnace tube outer wall substantially, greatly reduces the biography of heating tube in section of convection chamber
Hot property causes convection cell flue gas exit temperature to increase, the decline of stove heat transfer efficiency.In order to guarantee that stove has good heat transfer
Performance, it is therefore desirable to periodically furnace tube outer wall be cleaned.Furnace internally finned tube or studded tube may be up to tens of rice, diameter
At 0.1 meter or more, the tube sheet being used to support is distributed among it, tube sheet is 0.12 meter wide, it is higher by 0.03 meter of top layer boiler tube, and
Finned tube or the multi-layer intercrossed arrangement of studded tube, neighbouring finned tube or studded tube are arranged at triangular pitch or hexagon.
Currently, the cleaning of furnace tube outer wall dirt is divided into online cleaning and cleaning of stopping work, cleaning of stopping work is stopped transport the phase in stove
Between clean furnace tube outer wall dirt, main means be dry ice cleaning, chemical spray cleaning.Since these clean methods cannot clean
The finned tube or studded tube of depths bottom, cause cleaning efficiency low, cleaning effect is poor in furnace.Patent No. US 2014/
The patent of 0014141Al realizes mechanization by being mounted with the creeper truck of the swingable angle spray boom walking operations on furnace tube outer wall
Substitution is accomplished manually the cleaning to furnace tube outer wall, and with the cleanable multilayer furnace tube outer wall of the swing of spray boom, cleaning effect mentions significantly
Height, but this creeper truck cannot achieve whole process along boiler tube axis walking operations on furnace tube outer wall, while encounter sagging plate
When, it can not voluntarily cross tube sheet obstacle.
