HTAC, claims again regenerative combustion technology, can greatly improve the organic efficiency of fuel availability and fume afterheat, and energy consumption is reduced greatly, has used commonplace at present in steel mill.CN200810048112.9 has announced a kind of single heat storage type ladle baking facility.
In prior art, vacuum chamber baking adopts baking gun or non-heat-storage ladle roaster to toast conventionally.Report there are no RH heat-storage ladle roaster.Compare with the metallurgical tank such as ladle, Tie Bao, tundish, vacuum chamber total length is longer, for the large like this vacuum chamber of 11m, needs to guarantee the vacuum chamber upper and lower baking temperature of resistance to material uniformity simultaneously, adopts heat-accumulating baking device need to overcome this difficult point.
Summary of the invention
Technical problem to be solved by this invention is the technical deficiency over against above-mentioned existence, provide a kind of for large-scale vacuum chamber, can realize upper and lower baking temperature consistent, improve cured effect, improve baking quality, and save the heat accumulating type vacuum chamber baking system of and the end opening baking suitable for reading from vacuum chamber of the energy.
The technical solution adopted for the present invention to solve the technical problems is:
A heat accumulating type vacuum chamber baking system suitable for reading from vacuum chamber and end opening toasts, includes vacuum chamber body, it is characterized in that: the described upper and lower two ends of vacuum chamber body, are provided with baking system; Vacuum chamber body upper end is provided with baking lid, in baking lid, a plurality of regenerator are installed, heat storage is installed in regenerator, regenerator top is connected with blower system by the first reversing control valve, exhausting system and combustion gas, regenerator bottom is communicated with heat-accumulating burner, and heat-accumulating burner extends in vacuum chamber body; Described vacuum chamber body lower end is provided with vacuum chamber Inserting Tube, vacuum chamber Inserting Tube is outside equipped with frame, a plurality of regenerator are installed in frame, heat storage is installed in regenerator, regenerator bottom is connected with blower system by the second reversing control valve, exhausting system and combustion gas, regenerator top is communicated with heat-accumulating burner, and heat-accumulating burner extends in vacuum chamber body.
In such scheme, between described baking lid and vacuum chamber body, for being tightly connected, and be provided with fireclay insulating refractory in junction.
In such scheme, between described frame and vacuum chamber body, for being tightly connected, and be provided with fireclay insulating refractory in junction.
In such scheme, the heat-accumulating burner number that the regenerator in described frame connects is identical with the number of vacuum tube Inserting Tube, and each heat-accumulating burner is corresponding to a vacuum tube Inserting Tube.
In such scheme, the first described reversing control valve and the second reversing control valve are the setting of working at times, and the opening and closing in turn of both intersections realize vacuum chamber body top and the bottom Baking out in turn.
Innovative point of the present invention is:
1, upper and lower opening toasts simultaneously, is applicable to the large-tonnage vacuum chamber that length surpasses 11m.
2, adopt accumulation of heat nozzle to replace conventional spout, utilize regenerator to heat air, utilize regenerative combustion technology, first add hot-air, then vacuum chamber is toasted.
3, at bottom vacuum inserting tube, baking nozzle is installed, the principle that can utilize hot gas naturally to rise, bottom-heated can toast whole vacuum chamber.
When 4, upper and lower side is different, baking, works at times, can the in the situation that of identical amount of consumed gas, play better cured effect, has effectively saved the energy.
Beneficial effect of the present invention: can realize upper and lower baking temperature consistent, improve cured effect, improve baking quality, and shortened the dry and baking time of vacuum chamber, improve operating efficiency, also extended the service life of vacuum chamber, played the effect of energy-saving and emission-reduction simultaneously.
