The utility model content
In order to overcome the deficiency that existing tubular heater can only heat one or both media, the utility model provides a kind of multiple-effect integrated tubular heater, and the integrated tubular heater of this multiple-effect can be simultaneously to two or more medium heating.
The technical scheme that its technical problem that solves the utility model adopts is: the integrated tubular heater of a kind of multiple-effect, comprise the body of heater that supporting leg is housed, chimney, be installed in the burner of bottom of furnace body, the body of heater bottom is the radiant section that the ring-type radiant coil of vertical arrangement is housed, top is the convection section that transversely arranged snakelike heating tube in section of convection chamber is housed, it is characterized in that: between convection section and chimney, be provided with waste-heat recoverer, heat pipe is housed in the waste-heat recoverer, described radiant coil is that longitudinal fin is made the efficient heat transfer boiler tube, the boiler tube hoop uniform layout of dividing into groups, every group of boiler tube is connected to form circulus by one half bend, open two ends are respectively medium import and media outlet, and boiler tube positions fixing by the bearing support of upper of furnace body and bottom.
Described burner is evenly arranged ringwise.
Described medium import and outlet all are positioned at the radiant section top.
Described, waste-heat recoverer adopts the square chest structure of band central dividing plate, and heat pipe is welded on the central dividing plate.
Be provided with flue gas in the described chimney and regulate turnover panel.
The utility model burner apparatus adopts a plurality of burners, radiant coil adopts packet design, and each organizes the different medium of packing into respectively, therefore can reach the temperature difference that makes radiant section burner hearth zones of different by regulating each burner according to arts demand, thereby be implemented in the purpose that radiant section heats two or more different pressures, medium temperature simultaneously.
For example the negative pressure benzene removal technological requirement is to entering the rich oil of debenzolizing tower, the oil-poor of oil-poor and regenerator at the bottom of the tower heated simultaneously, both debenzolizing tower tubular heater and regenerator tubular heater circulated oil-poor (being heated to 220～240 ℃) at the bottom of rich oil (being heated to 190～200 ℃) that benzene needs and the debenzolizing tower and regenerator oil-poor (being heated to 270～290 ℃) heats to taking off respectively to adopt at present two tubular heaters, it is big to exist equipment investment, the maintenance cost height, the low deficiency that waits of the thermal efficiency adopts the integrated tubular heater of the disclosed multiple-effect of the utility model to heat above-mentioned three kinds of media simultaneously.
Burner, radiant section adopt longitudinal finned tube boiler tube, convection section to adopt hoop fin boiler tube, increased heat pipe-type flue gas waste heat recovery device so improved device heat efficiency efficiently because this equipment is integrated, reduced fuel consumption, equipment investment and floor space have been reduced, radiant section, convection section and chimney adopt lightening casting material to carry out adiabatic heat-insulation as furnace lining, the heat loss of minimizing equipment, also overcome the shortcoming that ceramic fibre class furnace lining often comes off, reduced the use and maintenance cost of equipment.
The utility model can heat the medium of two or more different temperatures, pressure simultaneously, has small investment, heat utilization efficiency height, long service life advantage for ease of maintenaince.
