The utility model environment-friendly type vertical boiler, the top seal of its inner bag and its exhaust opening is arranged on the bottom of epicoele, affixed smoke exhaust pipe on the exhaust opening, this smoke exhaust pipe is protruding from case peripheral wall, and the periphery wall of shell is provided with chimney at place, smoke exhaust pipe place; But the tuyere based on fuel on its stove seat liner is coal or industrial waste, character as chemical fibre, plastics, rubber, cotton etc. can be provided with 1-6 row from bottom to top, and the spacing between the bottom-up first air draft mouth is that 20-100mm, second to the 6th spacing of arranging are 20-250mm; The acclivitous inclination alpha of tuyere is 0 °-60 °, and the angle of inclination beta of itself and radial skew is 0 °-30 °.

The utility model has the advantages that: 1) liner and the wind chamber of the band tuyere that is provided with in the stove seat, for burner hearth has disposed the structure that sidespin ventilates, it makes flame form eddy current and sufficient oxygen and clean-burning time is arranged, its flue dust can be burnt in burner hearth fully, so its thermal efficiency height, the comparable prior art of fire box temperature exceed 300 ℃; The dedusting structure of the many backhauls of flue gas that 2) have in the body of heater makes soot emissions reach the waste gas emission standard of environmental protection defined; 3) the both available coal of the utility model boiler is made fuel, and the industrial waste that also can adopt the band calorific value is rubber, useless chemical fibre, waste cotton cloth, waste plastics etc. as usual, and it integrates economic benefit and social benefit.

To and contrast accompanying drawing by embodiment below is further described below the utility model.Have in the accompanying drawing:

Fig. 1 is the front view of the utility model environment-friendly type vertical boiler;

Fig. 2 is the A-A cutaway view among Fig. 1;

Fig. 3 is the B-B cutaway view among Fig. 2;

Fig. 4 and Fig. 5 are vertical boiler structure charts of the prior art, and wherein Fig. 4 is that its front view, Fig. 5 are the C-C cutaway views among Fig. 4.

Can see that from Fig. 1 and Fig. 2 the utility model environment-friendly type vertical boiler is by stove seat I with the body of heater II is affixed forms, the stove seat contains fire grate 1, burner hearth 23, air inlet 17, dog-house 19, contain a band valve seat 16 on the body of heater, gas seat 14, water level interface 13, hand hole 5, the inner bag 8 of the shell 7 of sewage draining exit 4 and a band exhaust opening 12, leave a cycle space between inner bag and the shell as chuck 20, the inner bag space is affixed diaphragm plate 11, the inner bag space is divided into epicoele 25 and cavity of resorption 24, water pipe 6 is housed respectively in epicoele and the cavity of resorption, these water pipe two ends all are communicated with the chuck space, cavity of resorption is connected with burner hearth, and cavity of resorption is communicated with epicoele by the fire tube 9 that is arranged on the inner bag sidewall.An affixed liner 31 with the concentric annulus cylindricality of stove seat in the stove seat I of the utility model boiler, the outer wall of this liner encloses wind chamber 2 with leaving one between the stove seat inwall, and is provided with tuyere 3 on the liner, and this tuyere makes the wind chamber be communicated with burner hearth.Can see that from Fig. 1 tuyere is inclined upwardly, the inclination angle between its center line and the horizontal line M is α, also can see the radial skew of it and stove seat from Fig. 3, that is the RADIAL N inclination β angle of its center line and stove seat.

The top seal of inner bag in the utility model boiler, and its exhaust opening 12 is arranged on the bottom of epicoele, connected on the exhaust opening smoke exhaust pipe 12 ', this pipe and periphery wall shell protruding from case peripheral wall is provided with chimney 26 at this smoke exhaust pipe place; Tuyere on the stove seat liner is provided with four rows in short transverse, and the spacing between the most beneath air draft mouth is 50mm, above it between three air draft mouths apart from being 100mm; The tuyere inclination alpha is that 22 °, β are 24 °.

The utility model boiler earlier to chuck 20 and water pipe 6 water inlets, is thrown in coal or industrial waste by dog-house 19 again, aweather mouthful 17 forced-air blasts of fighting then by water inlet 21 in use on fire grate 1.Air enters wind chamber 2, enter burner hearth 23 by the tuyere on the liner 3 again, the α angle because tuyere is inclined upwardly, again with stove seat radial skew β angle, therefore flame sidespin in burner hearth becomes the eddy current shape upwards, entering 24 pairs of water pipes of inner bag cavity of resorption by burner hearth heats, after this mouth 91 that advances from fire tube enters fire tube 9, outlet flue 92 from fire tube enters epicoele 25 again, in succession water in the chuck 20 and the water pipe in the epicoele are heated, the flue gas of Xing Chenging changes exhaust opening 12 downwards over to from the inner bag top at last, through smoke exhaust pipe 12 ' from chimney 26 dischargings, the water that heating finishes is emitted through sewage draining exit 4.What can be monitored by the water level meter of installing on the interface 13 (being represented among Fig. 2) the water yield in the chuck, and the sewage draining exit 4 of chuck bottom also can blowdown when cleaning chuck.Manhole 15 on the shell, hand hole 5 all use in deashing or maintenance, and must add seal cover (being represented among the figure) in normal operation of boiler.Sidespin aeration structure in the stove seat can make fuel combustion obtain sufficient oxygen, and make that flame forms eddy current, burning provides the time enough support, thereby realize the abundant burning of fuel, so fire box temperature exceeds 300 ℃ than the fire box temperature of the similar boiler of prior art; Simultaneously, flue dust is done flowing of many backhauls in body of heater, is promptly changed over to epicoele, is changed over to the epicoele bottom by last top of chamber and change chimney over to by the smoke exhaust pipe of epicoele bottom again by cavity of resorption, and its result stays in the body of heater dirt ash, so the flue gas that gives off reaches waste gas emission standard.
