Description
Technical field
The present invention relates to the boiler series products, particularly relate to a kind of every cigarette energy-saving vertical bent tube boiler.
Background technology
Miniature boiler is of many uses on the market, away from main body city, backwoodsman school, hospital, the processing enterprises such as small towns clothing, non-staple food need the miniature boiler heat supply, vast rural culture industry etc. all needs heat energy, moreover also have on the spot a large amount of reproducible biomass energies, such as tangerine bar, rice bran etc., all can be used for the boiler for domestic of small low-voltage.
The boiler for domestic of low capacity adopts vertical fire tube boiler mostly at present, or the version of improved vertical boiler with horizontal water tubes, it has simple in structure, the advantage that floor space is little, but ubiquity undercapacity, operating thermal efficiency are low, the fatal shortcoming of high fume temperature, the thermal efficiency of traditional product is about 50%, and exhaust gas temperature does not meet the requirement that national energy-saving reduces discharging all more than 300 ℃.
For increasing boiler inner conduit heating surface area, improve the thermal efficiency, the quantity that vertical curved water pipe fully is set satisfies the requirement of convection heating surface, because chamber structure restriction, the vertical curved water pipe that a greater number is set is subject to certain restrictions, and the steel consumption amount is significantly increased, and improves equipment cost.Because curved water pipe vertical layout in burner hearth takies certain space, the cross-sectional area of remaining flue is larger, and low capacity boiler smoke tolerance is also limited in addition, causes cigarette speed excessively low; And be parallel baffled, convection transfer rate is less, and flue gas is very short at residing time in furnace, and heat runs off.
Summary of the invention
The objective of the invention is provides a kind of smoke baffle plate energy-saving vertical bent tube boiler for solving the problem that the vertical bent water tube boiler convection transfer rate is low, the thermal efficiency is lower, and flue gas flow rate is accelerated, and flue gas stroke in stove lengthens, and improves the thermal efficiency.
The technical solution used in the present invention: a kind of every cigarette energy-saving vertical bent tube boiler, comprise drum, flue, burner hearth, burning chamber, upper lower fire grating, upper furnace door, lower furnace door, establish flue in the drum, be provided with upper and lower fire grate in the burner hearth, upper furnace door connects fire grate, lower furnace door connects lower fire grating, upper fire-grating is water-cooled grate tube, on the furnace grate tube access flue, mainly be at inboard wall of furnace curved water pipe to be set vertically, on the curved water pipe upper and lower port access flue, curved water pipe place arranges smoke baffle plate, and curved water pipe penetrates respectively smoke baffle plate.
And described curved water pipe arranges at least one group or array along the inboard wall of furnace circle.
And described curved water pipe along the setting of inboard wall of furnace circle is long and short curved water pipe, and short curved water pipe is arranged on long curved water pipe inboard.
And smoke baffle plate is garden shape plate, and smoke baffle plate external diameter garden is provided with the hole in week, and curved water pipe vertically penetrates the smoke baffle plate hole; The smoke baffle plate middle part is conic convex.
And curved water pipe arranges up and down two-layer smoke baffle plate at least, and curved water pipe vertically penetrates the smoke baffle plate hole.
And smoke baffle plate is hollow garden ring flat-plate, and is arranged on the flue place, is provided with the hole in the week of ring garden in the smoke baffle plate, and curved water pipe vertically penetrates the smoke baffle plate hole.
And curved water pipe penetrates the smoke baffle plate hole, and smoke baffle plate becomes the inclination angle with curved water pipe.
And, refractory coating is arranged on the smoke baffle plate.
The present invention compared with prior art also has following major advantage:
1, stove employing of the present invention is arranged along inboard wall of furnace curved water pipe vertically is set, and in flue, fully arrange the vertical curved water pipe group of array, temperature is high in the flue, increase convection heating surface, the hot-water line heat transfer area increases, the convection heating surface that burning chamber and curved water pipe form, being furnished with strengthening and heat transferring device therebetween increases flue gas flow rate and reaches desirable heat-transfer effect.
2, owing to being provided with three layers or multilayer smoke baffle plate at vertical curved water pipe, make thermal-flame or flue gas many around several curved in stove, the time of staying of prolong smoke in stove, reach the purpose of abundant heat exchange, because changed flue gas flow direction, make the parallel baffled of flue gas become transversal flow simultaneously, it is large that convection transfer rate becomes, correspondingly improve flue gas flow rate, obtained the good result of achieving many things at one stroke.
3, because smoke baffle board device is simple in structure, and processing performance is good, conic convex is arranged at garden shape smoke baffle plate middle part, the fuel dust stratification can't smoke baffle plate on pile up, dust falls automatically, is easy to remove; The hollow ring smoke baffle plate is installed on the flue, is convenient to the flue gas turning and rises, and plays function of heat insulation at sheet metal perfusion fire proofed wood simultaneously.
4, owing to adopting curved water pipe place that the multilayer smoke baffle plate is set, curved water pipe penetrates respectively smoke baffle plate, increase flue inner conduit heating surface area, thermal-flame or flue gas stroke in stove is longer, the time of staying of prolong smoke in stove, improve the thermal efficiency, the thermal efficiency is higher than 80% energy-conservation requirement, reaches energy-saving effect.
