Abstract
The invention relates to a direct-fired blast heater. In the invention, an adjusting air valve (5) is arranged between a combustion chamber (13) and a hot air chamber (14), wherein the hot air chamber (14) is internally equipped with a primary-efficiency filter (4), a medium-efficiency filter (2) and an air feeder (3); the combustion chamber (13) is internally equipped with a combustion liner (6), the combustion liner (6) is equipped with a crescent groove, and a porous heat transfer plate (12) on the bottom of the groove and the combustion liner (6) are welded into a whole; and the outer side of the porous heat transfer plate (12) is equipped with a crescent porous adjusting plate (11) which can be movably adjusted relative to the longitudinal direction. The direct-fired blast heater has the advantages of simple structure, high heat efficiency, adjustable heat flux and high temperature-control accuracy, and can replace the traditional indirect fuel gas exchanger; and the manufacturing cost of the direct-fired blast heater is one third of that of the indirect fuel gas exchanger.
Description
Technical field
The present invention relates to the air blowing heater in the paint line, particularly a kind of direct-fired blast heater.
Background technology
At present paint industry air-supply heating system, when adopting the hot-blast stove heating, traditional method has two kinds: the one, the hot-blast stove of utilization indirect type, expense is high, the thermal efficiency is low, it is slow, difficult in maintenance to heat up, the device fabrication cost is high, the equipment making workload is large, and is many with material, and thermal waste is serious; The 2nd, select the direct-fired firing equipment of U.S. MAXON, expense is high, fittings supply is difficult, equipment investment cost is high.
Summary of the invention
Technical barrier to be solved by this invention is, overcomes above-mentioned deficiency, and a kind of simple in structure, easy to use, the thermal efficiency is high, cost is low direct-fired blast firing equipment is provided.
Technical solution of the present invention is, comprises combustion chamber body 13 and hot air chamber body 14, is provided with adjusting air valve 5 between combustion chamber body 13 and the hot air chamber body 14, and combustion chamber body 13 is provided with air inlet 7, and hot air chamber body 14 is provided with air outlet 1; Be provided with low efficient filter 4, medium effeciency filter 2 and pressure fan 3 in the hot air chamber body 14, be provided with combustion barrel 6 in the combustion chamber body 13, the nozzle 10 that is fixed in the combustor 9 on the combustion chamber body 13 is stretched in the end of combustion barrel 6, it is characterized in that: combustion barrel 6 is provided with a crescent groove, and porous heat transfer plate 12 and the combustion barrel 6 of bottom portion of groove are welded as a whole; The outside of porous heat transfer plate 12 is provided with the relatively crescent porous adjustable plate 11 of its longitudinally-moving adjusting.
The present invention is compared with the prior art the advantage that possesses, and is simple in structure, and the thermal efficiency is high, and heat flux is adjustable, and temperature-controlled precision is high, alternative traditional indirect type combustion gas interchanger, and cost is 1/3rd of traditional indirect type combustion gas interchanger.

The specific embodiment
The present invention includes combustion chamber body 13 and hot air chamber body 14, be provided with adjusting air valve 5 between combustion chamber body 13 and the hot air chamber body 14, combustion chamber body 13 is provided with air inlet 7, and hot air chamber body 14 is provided with air outlet 1; Be provided with low efficient filter 4, medium effeciency filter 2, pressure fan 3 in the hot air chamber body 14, be provided with combustion barrel 6 in the combustion chamber body 13, combustion barrel 6 is fixed in the combustion chamber body 13 by support 8.Combustor 9 is fixed on the combustion chamber body 13, and its nozzle 10 is stretched in the end of combustion barrel 6.
During supply air system work of the present invention, blower fan 3 starts, and new general mood stream enters in the combustion chamber body 13 from air inlet 7.When supply air system need to heat, open air supply system, combustor 9 igniting, flame by the pressure that porous adjustable plate 11 is regulated in the combustion barrel 6, is controlled the heat flux that flame is gone out in combustion barrel 6 internal combustion simultaneously.The a part of cylindrical shell conduction by combustion barrel 6 of heat, and most of heat distributes from the perforation of porous adjustable plate 11 and porous heat transfer plate 12, graviational interaction at blower fan 3 is issued to maximal efficiency, adjusting air valve 5 enters low efficient filter 4, after sending into the medium effeciency filter filtration by blower fan 3 again, send into the application station through air outlet 1.
