Description

A kind of direct-fired air-supply heater

Technical field

The utility model relates to the air-supply heater in the paint line, particularly a kind of direct-fired air-supply heater.

Background technology

The heating system of paint industry air-supply at present, when adopting the hot-blast stove heating, traditional method has two kinds: the one, the hot-blast stove of utilization indirect type, the expense height, the thermal efficiency is low, intensification is slow, difficult in maintenance, device fabrication cost height, equipment making workload are big, and be many with material, and thermal waste is serious; The 2nd, select the direct-fired firing equipment of U.S. MAXON for use, expense is high, fittings supply is difficult, equipment investment cost is high.

Summary of the invention

Technical barrier to be solved in the utility model 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 air-supply firing equipment is provided.

Technical solution of the present utility model is, comprises combustion chamber body 13 and hot blast chamber body 14, is provided with between combustion chamber body 13 and the hot blast chamber body 14 to regulate air-valve 5, and combustion chamber body 13 is provided with air inlet 7, and hot blast 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 blast 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 the 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 crescent porous adjustable plate 11 of its longitudinally-moving adjusting relatively.

Combustion barrel 6 cylindrical shell windward sides are round, are double-layer porous plate by the wind face, and hot-blast outlet is a flow guiding type.

Combustion barrel 6 is fixed in the combustion chamber body 13 by support 8.

The utility model is compared with the prior art the advantage that is possessed, and is simple in structure, thermal efficiency height, and heat flux is adjustable, the temperature-controlled precision height, alternative traditional indirect type combustion gas interchanger, cost is 1/3rd of a traditional indirect type combustion gas interchanger.

Wherein: the 1-air outlet, the 2-medium effeciency filter, the 3-blower fan, 4-low efficient filter, 5-are regulated air-valve 6-combustion barrel, 7-air inlet, 8-support, 9-combustor, 10-nozzle, 11-porous adjustable plate, 12-porous heat transfer plate, 13-combustion chamber body, 14-hot blast chamber body.

The specific embodiment

The utility model comprises combustion chamber body 13 and hot blast chamber body 14, is provided with between combustion chamber body 13 and the hot blast chamber body 14 to regulate air-valve 5, and combustion chamber body 13 is provided with air inlet 7, and hot blast 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 blast 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.

Combustion barrel 6 is provided with a crescent groove, and the porous heat transfer plate 12 and the combustion barrel 6 of bottom portion of groove are one, can direct punching form on combustion barrel 6, also the porous heat transfer plate 12 after the punch forming can be welded on the combustion barrel 6; The outside of porous heat transfer plate 12 also is provided with the adjustable crescent porous of its longitudinally-moving adjustable plate 11 relatively.Be provided with two slots on combustion barrel 6, porous adjustable plate 11 can carry out activity and regulate in insert slot.Porous adjustable plate 11 can be regulated the throughput of flame heat regulating in the combustion barrel 6.Be used to be maximum heat flux when logical when aperture on the porous adjustable plate 11 and aperture on the porous heat transfer plate 12 are relative fully; When the aperture on aperture on the porous adjustable plate 11 and the porous heat transfer plate 12 staggered, heat flux reduced, and regulated the heat flux of flame in the combustion barrel 6 with this.

Combustion barrel 6 cylindrical shell windward sides are round, are double-layer porous plate by the wind face, and hot-blast outlet is to prevent that the negative pressure that air flow produces is designed to flow guiding type.

During the work of the utility model supply air system, 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 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 of heat by combustion barrel 6, 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, regulate air-valve 5 and enter 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.
