The water cooling protection structure has the advantages that the service life of the furnace wall is prolonged, and the thermal stress working environment for a steel structure of a hearth body is effectively improved.
Description
Technical field
The utility model is primarily aimed at high-temperature plasma vapourizing furnace, field of furnaces, is specifically to utilize a kind of water-cooled safeguard structure to reach near the purpose of fire-resistant furnace wall and body construction the high temperature aperture area such as protection burner hearth burner or plasma torch.
Background technology
In fuel combustion, gasification use process; Particularly in the gasifying process of low calorie fuels; In order the energy in the fuel to be converted into the synthetic gas chemical energy to greatest extent, effectively reduce the coal-tar middle oil generation of synthetic gas, then keeping under certain gasification temperature situation; The burner hearth planted agent takes to reduce the measure of heat absorption and heat lost by radiation as far as possible, and high-temperature burner hearth is extensively adopted.The refractory brick material lifetime then becomes the bottleneck of vapourizing furnace economical operation; Because the gasification temperature field in furnace is a kind of inhomogeneous, unsettled temperature field; Through regular meeting refractory materials ablation, erosion appear near the aperture area such as burner, combustion-supporting torch particularly; Even the phenomenon of local burning fusing, have a strong impact on flame retardant coating work-ing life.
In addition, in vapourizing furnace burner hearth aperture area, the steelwork body receives the fume high-temperature radiation, and temperature is very high, and the steel structure material thermal stresses is had relatively high expectations.Because the existence of aperture area, this has improved vapourizing furnace body cost with potentiality ground.
Summary of the invention
The technical problem that the utility model will solve provides a kind of vapourizing furnace or roasting kiln high temperature aperture area water-cooled safeguard structure of being used for; To solve high temperature aperture area flame retardant coating difficult arrangement in the adiabatic furnace; Problem such as flame retardant coating is prone to pitting corrosion, come off; Furnace wall work-ing life can be prolonged, simultaneously, burner hearth body steelwork thermal stresses work condition environment can be effectively improved.
The technical scheme of taking for solving the problems of the technologies described above is:
A kind of vapourizing furnace or roasting kiln high temperature aperture area water-cooled safeguard structure of being used for comprises: flange, middle adapter, cooling jacket, interior pin, outer pin, interface inlet tube, interface fairlead, inner sleeve; Its constitutional features is: flange is connected with cooling jacket through intermediate head; Cooling jacket places the high-temperature flame-proof layer, and supports through inner sleeve; The interior pin of inner sleeve disposed inboard also tamps refractory matter; Cooling jacket is arranged to be used to strengthen between ramming mass and furnace wall and the chuck to fire end or the outside and is pinned outside close-connected; The interface inlet tube and the interface fairlead that are connected with intermediate head and cooling jacket of setting respectively on the flange.
Wherein, cooling jacket is the high coil-like cooling jacket of thermal conductivity; The coil pipe caliber needs to decide according to the interface size of different burners or flare apparatus.
Wherein, cooling jacket is copper.
Wherein, cooling jacket coil pipe caliber is 20～50mm.
Wherein, pin in inner sleeve disposed inboard 5～7 rows; Cooling jacket is arranged 5～7 exclusive pins to fire end.
All joints are the inclusion seal welding.
During work, cooling working medium flows into from the interface inlet tube of flange, flows through intermediate head, gets into the interface fairlead that is back to flange after heat absorption heats up in the cooling jacket and flows out, and gets into follow-up other technologies again or is cooled the back recycle.
Wherein, cooling working medium is a water, also can carry the higher fluid of heat flow density for other, as contain phase transformation particulate solution etc.
Wherein, water coolant temperature rise in cooling jacket 3 coil pipes should be controlled in 5.5 ℃.
The utility model utilizes cooling working medium such as water-cooled heat exchange principle, with embedding the jacket structured as interchanger of flame retardant coating, realizes reducing the temperature of the local flame retardant coating of high temperature aperture area, improves the purpose of aperture area steelwork thermal condition environment.
The beneficial effect of the utility model is:
1: solved the flame retardant coating that aperture area working temperatures such as adiabatic furnace burner, combustion-supporting torch, plasma torch are high, operating mode is badly brought be prone to lose efficacy, perishable, problem such as be prone to come off.
2: the thermal stresses work condition environment of effectively having alleviated burner hearth aperture area steelwork body.
3: reduced the harm risk of the inclined to one side fire of burner in the actual moving process or torch to the aperture area flame retardant coating.
Description of drawings:
Below in conjunction with embodiment and accompanying drawing the utility model is described further.
Fig. 1 is a kind of structural representation that is used for vapourizing furnace high temperature aperture area water-cooled safeguard structure;
Fig. 2 is that the A of Fig. 1 is to view.
