Abstract
The utility model discloses a coal-fired smoke-eliminating vertical boiler which improves original vertical boiler. Grate bars which are at the middle of the grate are in linear parallel arrangement and the around grate bars are in concentric circles arrangement, and a heat-storing device is arranged at a top of a furnace, and a wind-sending device which is divided into two to five-layers is arranged inside the furnace, and a cylinder shape wind-resisting device is arranged under the grate bars of the grate which are in linear parallel arrangement. The utility model has the advantages of compact structure, full coal combustion, saving energy, convenient maintenance, good smoke-eliminating and dusting effect and according with the national environmental protection requirements, etc.
Description
The utility model relates to a kind of coal-fired smoke elimination vertical boiler, belongs to a kind of vertical boiler.
Existing coal-fired vertical boiler, the overwhelming majority is following to wind for fire grate, this boiler combustion is insufficient, and efficient is low, and the flue gas dust concentration height of discharging from chimney, do not reach national requirements for environmental protection, indivedual also have in burner hearth, be provided with air outlet, though thisly help burning of coal, it is more abundant to burn, but this wind of giving can not form air curtain, still has volume of smoke to discharge from chimney.
The purpose of this utility model be to overcome the weak point in the background technology and provide a kind of smoke medicining dust-removing effect good, make the fire coal smoke elimination vertical boiler that coal combustion is abundant, energy-conservation, rational in infrastructure, be convenient to keep in repair.
The purpose of this utility model is achieved in that it comprises body of heater, water inlet pipe, outlet pipe, fire door, burner hearth, fire grate, shoot door, bellows, chimney etc., the middle fire bars of its fire grate is that straight line parallel is arranged, fire bars is that concentric circles is arranged on every side, establishes 2～5 layers of wind apparatus of giving of giving wind in the burner hearth; Roof of the furnace is provided with heat-storing device; The fire bars below that straight line parallel is arranged is provided with a columnar choke device.
The purpose of this utility model can also realize by following technical measures: chewed for wind apparatus by ajutage and wind and form, ajutage is communicated with chamber on the bellows by the wind pushing hole of chamber on the bellows, the wind on the same horizontal line chew into one deck to wind.Heat-storing device is a hemispherical, is fixed on the dividing plate, and bellows are the live body bellows, places on the body of heater of fire grate below, and bellows are disc, and the centre has dividing plate to be divided into upper and lower two Room, and top, last chamber is provided with wind pushing hole, and following chamber interior walls is provided with wind and chews.
The utility model compared with prior art has following advantage:
1, compact conformation is reasonable;
2, because the middle fire bars of fire grate employing is that straight line parallel is arranged, fire bars is that concentric circles is arranged on every side, the two is in conjunction with constituting fire grate, and below part arranged in a straight line, be provided with the cylindrical shape choke device, concentric circles fire grate part is corresponding with the air blast direction, thereby increased air output under the fire grate, top coal is fully burnt, form the combustion high temperature district, and the straight line parallel aligning part makes coal on this part fire grate at high temperature by destructive distillation because air-supply is insufficient, the completing combustion under the air curtain effect of the fuel gas of generation, thereby coal combustion is abundant, economizes on coal;
3, owing to establish 2～5 layers of wind apparatus of giving of giving wind in the burner hearth, the multilayer ajutage promptly is set around the inner bag of combustion zone, the wind of a plurality of ajutages is chewed simultaneously to the boiler air blast during burning, form the multilayer air curtain, the flue gas that coal combustion on the fire grate produces is trapped in the burner hearth under the stopping of air curtain, under the condition of high temperature oxygenation, burn away, flue gas is through the effect repeatedly of multilayer air curtain, final realization completing combustion, pure hot gas breaks through air curtain and enters the heat convection district and carry out heat exchange, thereby having improved the thermal efficiency, smoke medicining dust-removing effect is good, meets national requirements for environmental protection fully;
4, because roof of the furnace is provided with heat-storing device in order to regulate fire box temperature, when in the burner hearth during coal-fired normal combustion, the fire box temperature height, the heat-storing device storage of absorbing heat, when fire box temperature is reduced, heat-storing device carries out heat release improving fire box temperature, thereby has realized burner hearth to be rapidly heated and burn.
