Description
Technical field
The utility model relates to a kind of boiler, particularly a kind of membrane wall structure self-contained boiler of spiral-flow type burning biomass particle.
Background technology
Biomass granule fuel is that living beings are come by mechanical presses moulding, and it is a kind of desirable regenerative resource.Living beings, compared with fossil fuel, have the following advantages: 1, recyclability; 2, low contaminative: SOx, NOx concentration of emission are low; 3, when living beings are as fuel, in growth cycle, the clean discharge capacity of the carbon dioxide of atmosphere is similar to zero, can effectively alleviates greenhouse effects.
Now the biomass burning particle boiler of operation is all by old formula chain furnace or fixed grate boiler transformation, although the characteristic of based on fuel aspect much, boiler is improved,, in the time of boiler operatiopn, still exist following problem:
1. temperature field skewness in burner hearth, fuel gas and air mix the bad phenomenon of the impact burning such as inhomogeneous, thereby cause the factors such as boiler over-emitting black exhaust, gas incomplete combustion heat loss is large, boiler radiation loss is large, exhaust gas temperature is high; Cause the thermal efficiency of boiler very low, the situations such as CO, NOx etc. are poisonous, noxious gas emission concentration height, waste of fuel is large, big for environment pollution.
2. boiler both walls all adopts light pipe, brick construction, after operation a period of time, easily produce that burner hearth inleakage is large, furnace wall accelerates to damage, smolder and the high temperature flying dust situation such as emerge, cause boiler room seriously polluted, more seriously affect operations staff's life safety and healthy.
3. because chimney arch and Secondary Air do not have preferred arrangement (being mainly because original structure can not effectively be arranged), cause still having a large amount of fixed carbon there is no after-flame at fire grate afterbody (rear arch bottom), need to just can make by manually poking fire fuel again return to combustion zone burning, this process has increased workman's labour intensity, and transforms to such an extent that more bad labour intensity is larger.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of over-emitting black exhaust phenomenon of eliminating is provided, reduce gas incomplete combustion heat loss, improve the thermal efficiency of boiler, save the membrane wall structure self-contained boiler of the spiral-flow type burning biomass particle of the energy and reduction toxic and harmful concentration, to solve above-mentioned problems of the prior art.
The technical scheme solving the problems of the technologies described above is: a kind of membrane wall structure self-contained boiler of spiral-flow type burning biomass particle, comprise boiler body, described boiler body comprises drum, burner hearth, charging traveling-grate stoker and secondary furnace, burner hearth forms by being provided with middle part water conservancy diversion partition wall and left hearth baffle for separating the left side burner hearth and the right side burner hearth that are interconnected, between described drum and water conservancy diversion partition wall top, middle part, form the smokestack that is communicated with left side burner hearth and right side burner hearth, described furnace outlet place, right side is provided with secondary air channel, described feeding chain bar oven ranking is in right side burner hearth bottom, described left side burner hearth is communicated with secondary furnace, burner hearth sidewall is film water cold wall structure, described burner hearth is outside equipped with heat-insulation layer.
Described heat-insulation layer is lightweight thermal insulation layer.
In described middle part water conservancy diversion partition wall, be furnished with down-comer.
The utility model is at self-contained boiler burner hearth both sides design film water cold wall structure; At burner hearth middle part design water conservancy diversion partition wall, form eddy flow.Burner hearth is divided into left side burner hearth and right side burner hearth by midfeather, and the burning of fuel is carried out in the burner hearth of right side.Flue gas flows out from the window (C in Fig. 4) of drum, midfeather and right side membrane wall composition, because the velocity of flue gas coming on aditus laryngis is larger, effect at drum place due to centrifugal force, flue gas will flow along drum outer wall, and enter left side burner hearth from the tangential direction of drum through smokestack (C in Fig. 4) jet, under the centrifugal force that flue gas produces at a high speed at self, rotate 2-3 circle.
The utility model, according to the feature of biomass granule fuel composition, element and grey characteristic, improves the burning of fuel in chain grate boiler burner hearth.Strengthen emphatically the burning in burner hearth of volatile matter and fixed carbon, eliminate over-emitting black exhaust phenomenon, reduce gas incomplete combustion heat loss, improve the thermal efficiency of boiler, save the energy; By the improvement of burning, the concentration of the toxic and harmful such as CO, NOx is dropped to below the concentration of emission of law, rules and regulations, reach safety dumping; Boiler both sides adopt full film type wall structure, reduce boiler heat radiation, leak out, smolder and the high temperature flying dust situation such as emerge, improve the cleanliness factor of boiler room, greatly improve operations staff's working environment and labour intensity.
The utility model also has following beneficial effect:
1. aspect burning and efficiency, apply boiler and the comparison of old-fashioned transformation boiler of the utility model design, the utility model is over-emitting black exhaust not, and gas incomplete combustion heat loss reduces by 1.5%, and heat loss of imperfect solid combustion reduces by 5%.Radiation loss etc. is included, the boiler of identical parameters more in the past, the boiler of application the utility model design can improve 6%-8% aspect boiler thermal output.
2. the open grate area boiler minimizing 20% of identical parameters more in the past, because both sides adopt membrane wall structure, the consumption of metal is less slightly, and the use of refractory brick but significantly reduces, and approximately reduces 60%.
Below, the technical characterictic of the membrane wall structure self-contained boiler of a kind of spiral-flow type burning biomass particle to the utility model is further described in conjunction with the accompanying drawings and embodiments.
