Description
Technical field: the utility model relates to a kind of chimney flue type biogas wall hanging stove.
Background technology: in the prior art, complicated component, combustion heat value be low, have certain corrosive biogas burning after, produce a large amount of sulfur contained high temoperature flue gases, corrode the fin-type copper heat exchanger easily, so that the obstruct smoke passage, reduce the heat exchange efficiency of heat exchanger.In order to prevent that heat exchanger is corroded, the heat exchanger of biogas wall hanging stove can adopt the stainless steel material manufacturing, but because stainless steel has the slow material behavior of conducting heat, uses the heat exchange efficiency of the conventional fin-type heat exchanger of stainless steel manufacturing not reach instructions for use.Cause there is sulfur contained high temoperature flue gas corrosion heat exchanger defective such as the exhaust gases passes that causes blocks, and the heat exchange efficiency of heat exchanger is lower.In order to overcome these defectives, chimney flue type biogas wall hanging stove is developed.
Summary of the invention: technical problem to be solved in the utility model is that a kind of chimney flue type biogas wall hanging stove will be provided, it can prevent sulfur contained high temoperature flue gas corrosion heat exchanger effectively, the exhaust gases passes of avoiding the sulfur contained high temoperature flue gas to cause blocks, thereby improves the heat exchange efficiency of heat exchanger.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises exhaust fume collecting hood, heat exchanger, burner, gas ratio valve, three-way solenoid valve, plate type heat exchanger, air intake plate, water pump, described burner is installed in the air intake plate top, heat exchanger is installed in the burner top, exhaust fume collecting hood is installed in the heat exchanger top, be provided with straight tube, bend pipe in the heat exchanger, straight tube is communicated with bend pipe, described heat exchanger is by the stainless steel material manufacturing, and straight tube, bend pipe are flat oval shape steel pipe.
Described straight tube, bend pipe are seamless cold flat oval shape steel pipe.
Described straight tube, bend pipe are connected by inferior arc welding.
Spacing between the adjacent straight tube is 5～60mm, and the distance between the tangent line of straight tube cross section two terminal circle wall top is 30～150mm, and the distance between the straight wall of straight tube is 3～50mm, and the wall thickness of straight tube is 0.5～10.0mm.
Spacing between the described adjacent straight tube is 10mm.
Distance between the tangent line of described straight tube cross section two terminal circle wall top is 50mm, and the distance between straight wall is 10mm, and wall thickness is 1.0mm.
The utility model is compared the beneficial effect that is produced with prior art:
1, because the utility model adopts described heat exchanger by the stainless steel material manufacturing, straight tube, bend pipe are the structure of flat oval shape steel pipe, so it can prevent sulfur contained high temoperature flue gas corrosion heat exchanger effectively, the exhaust gases passes of avoiding the sulfur contained high temoperature flue gas to cause blocks, thereby improves the heat exchange efficiency of heat exchanger.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure enlarged drawing of heat exchanger 2 among Fig. 1.
Fig. 3 is the cross section enlarged drawing of straight tube 9 among Fig. 2.
The specific embodiment: referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, present embodiment comprises exhaust fume collecting hood 1, heat exchanger 2, burner 3, gas ratio valve 4, three-way solenoid valve 5, plate type heat exchanger 6, air intake plate 7 and water pump 8.Burner 3 is installed in air intake plate 7 tops, and heat exchanger 2 is installed in burner 3 tops, and exhaust fume collecting hood 1 is installed in heat exchanger 2 tops.Exhaust fume collecting hood 1 adopts the stainless steel material manufacturing, is difficult for being corroded.Be provided with straight tube 9 in the heat exchanger 2, bend pipe 10, straight tube 9 is communicated with bend pipe 10, straight tube 9, bend pipe 10 is flat oval shape steel pipe, adopt seamless cold flat oval shape steel pipe (D-4 flat oval shape pipe) in the present embodiment, spacing between the wherein adjacent straight tube 9 is 5～60mm, select 10mm in the present embodiment, distance between straight tube 9 cross section two terminal circle wall top tangent lines is 30～150mm, select 50mm in the present embodiment, distance between straight tube 9 straight walls is 3～50mm, select 10mm in the present embodiment, the wall thickness of straight tube 9 is 0.5～10.0mm, selects 1.0mm in the present embodiment, adopts this structure can increase the contact area of flue gas and heat exchanger 2, thereby the lifting heat exchange efficiency, the inferior arc-welding of whole use connects.Change fume exhausting type into possibility that the nature exhaust is corroded with the parts that reduce in the high-temperature flue gas runner, and natural exhaust structure is succinct relatively, has reduced amount of parts, has reduced manufacturing cost and production difficulty.
During work, biogas enters burner 3 through behind the gas ratio valve 4, and air flows into from air intake plate 7, and biogas is discharged from exhaust fume collecting hood 1 after the high-temperature flue gas that burner 3 burnings produce passes through heat exchanger 2 heat exchange.When heat exchanger 2 heat exchange efficiencies do not reach when requiring, can change heat exchange efficiency with wall thickness by changing the spacing between the straight tube 9, the distance between the tangent line of cross section two terminal circle wall top, the distance between straight wall: increase the area that high-temperature flue gas contacts with heat exchanger 2 by the distance that strengthens between straight tube 9 cross section two terminal circle wall top tangent lines; The wall thickness that reduces straight tube 9 is accelerated the speed that heat is delivered to water, and the distance and the spacing between the adjacent straight tube that reduce between straight tube 9 straight walls increase air drag, the high-temperature flue gas flow velocity is reduced, thereby increase heat-exchange time, can improve the heat exchange efficiency of heat exchanger 2.
