Background technology
China is as world today's boiler for producing and use maximum countries, and Industrial Boiler is applied to each and every one industry of productive life, and how on existing basis, improving Industrial Boiler efficiency further, realizing the object of energy-conserving and environment-protective, is the problem be worthy of attentive consideration.Existing Industrial Boiler, in order to Mist heat recovering, improves boiler efficiency, and usually adopt boiler one or two fin-tube type heat exchanger external, this just makes whole steam generator system compact not; And existing boiler turns smoke-box is generally dry back structure, during boiler operatiopn boiler's tube-plate or panel temperature higher, not only radiation loss is comparatively large, and requires higher to heat-resisting, the sealing property of tube sheet or panel and processing technology.The Industrial Boiler of the current overwhelming majority all adopts that flue is underlying, flue structure, and namely flue is arranged on lower housing portion, and flue gas is parallel baffled smoke pipe heat-transfer surface in pipe, and the coefficient of heat transfer is lower.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides integral type wet back of the body central flame flame boiler entirely.The present invention adopts following technical scheme:
Integral type is wet back of the body central flame flame boiler entirely, and critical piece has burner, housing, flue, turns smoke-box, box-type heat exchanger, energy-saving appliance and homogenizing plate, it is characterized in that: boiler shell is cuboid, and flue and box-type heat exchanger lay respectively at housing upper and bottom; Energy-saving appliance application spiral fin coil, adopts integrated design to be welded in housing afterbody; Flue, turn smoke-box and box-type heat exchanger is all immersed in stove water, form complete wet back structure; Strile-back type centered by flue combustion mode.
The spiral fin coil of described energy-saving appliance and box-type heat exchanger share one piece of lower perforated plate, spiral fin coil presses equilateral triangle distribution on tube sheet, spiral fin coil just adopts light pipe to box-type heat exchanger smoke outlet pipeline section, and remainder adopts the spiral fin coil that spacing is larger.
Homogenizing plate is installed by the return pipe import department of described energy-saving appliance, and lower end delivery port communicates with housing Nei Shui side.Described homogenizing plate is the orifice plate of band through hole, and the corresponding energy-saving appliance heat exchanger tube of through hole is arranged.
Described box-type heat exchanger is docked by four pieces of slab normal and is welded, and both ends of the surface are as smoke entrance; Its horizontal width is substantially equal with flue diameter, and internal vertical arranges many heat exchanger tubes, and its upper and lower panel is as tube sheet, heat exchanger tube is arranged according to staggered triangular pitch on tube sheet, and being vertically fixed on tube sheet by welding, heat exchanger tube can adopt smooth heat exchanger tube, also can adopt outer fin heat exchange pipe.
Compared with prior art, the invention has the beneficial effects as follows: 1. energy-saving appliance adopts integrated design to make boiler overall structure compacter, and overall thermal efficiency is higher, applies spiral fin coil simultaneously, also provide enhanced the disturbance of flue gas while increasing heat exchange area, improve heat exchange efficiency; 2. adopt complete wet back structure, avoid high-temperature flue gas butt welded seam and cause damage, improve the service life of boiler, be conducive to reducing casing surface temperature simultaneously, reduce heat loss; 3. boiler adopts central flame flame formula, increases Radiant exothermicity, improves the heat exchange efficiency of boiler, simplifies follow-up heat convection face, reduces boiler manufacture cost; 4. arranging homogenizing plate makes boiler blow-down water evenly flow through energy-saving appliance heat-exchanging tube bundle, improves heat exchange efficiency, prevents because backwater skewness causes energy-saving appliance hot-spot.5. in box-type heat exchanger, heat exchanger tube employing is vertically staggered in arrangement, flue gas transversal flow heat exchanger tube improves flue gas and heat exchanger tube convection transfer rate effectively, adopt simultaneously flue upper, box-type heat exchanger under arrangement, the overall heat exchange stroke of flue gas and stove water is made to form adverse current, reach the effect that heat exchange total temperature difference is maximum, improve heat exchange efficiency.
