2) Du Te ventilation combustion-supporting system
Can reduce every brick of coal consumption 100 kilocalories.The back fiery ventilation combustion-supporting system of this kiln uniqueness is that the one-time stacking-burning annular kiln of common annular kiln and other types does not have.Be by the fire grate formation of " babysbreath " at the bottom of firing chamber's outer vent and the kiln, can make fuel completing combustion, do not have combustible components such as harmful carbon monoxide, methane, sulphur steam in the flue gas that is produced.Do not contain remaining combustible in the residue (ashes) that burning back produces, and other kiln types that do not have this system are not accomplished.
The one-time stacking-burning annular kiln of common annular kiln and other types is in the imperfect combustion state often, has harmful fuel gas in the flue gas, contains residual coal in the slag.Because the effect of novel one-time stacking-burning annular kiln ventilation combustion-supporting system, every brick can reduce coal consumption 100 kilocalories at least.Calculate by on average producing 14 10,000 bricks every day daily, can save 2 tons of standard coals (per kilogram standard coal 7000 kilocalories) every day
Reduce discharging environmental protection
1), Du Te super internal combustion roasting technique
Needs because of the dry humidity discharging of one-time stacking-burning annular kiln, need to adopt super internal combustion roasting technique, promptly be the interior fuel (gangue, slag etc.) that in the blank of not moulding, adds the calorific value that is no less than per kilogram 500 kilocalories, after the moulding during base substrate roasting, fuel is in the base substrate internal combustion, the formation lividity is felt terribly worried, thereby reaches into the intensity behind the brick, and need not the roasting of external throwing coal.And this moment, fuel wrapped up through the liquid phase that the residue (ash and slag) that internal combustion produced has been produced behind high temperature sintering by adobe, can not discharge outside the base substrate, because of need not a large amount of external putting-in coals, do not have in the direct discharged air of volume of smoke yet, thereby significantly reduced the pollution of dust and pernicious gas atmosphere.
2), Du Te kiln body smoke evacuation system
The smoke evacuation system of common traditional annular kiln is that fuel is after burning, directly be discharged in the atmosphere through the air channel by smoke exhaust fan or chimney, and novel tendencies pipeline in one step piling up firing annular kiln directly is not discharged into this flue gas in the atmosphere, but this flue gas is used as drying medium, effect by the air channel blower fan, deliver in the structure of the dry humidity discharging band in the kiln body, from dry humidity discharging band, installed in the wet base seam of kiln and passed (especially porous hollow adobe), formed one tens meters long " screen pack ", flue dust after the burning and harmful substance also can adhere to wet base surface, by the effect of " filter screen ", thereby purified dust and the harmful substance of row greatly to atmosphere.
3), Du Te bootstrap system and ventilation combustion-supporting system
As previously mentioned, because fire coal has been saved in the effect of this system, also reduced the discharging of waste gas such as carbon dioxide, useless dirt, waste residue accordingly, narration no longer.
The flue gas that smoke exhaust fan of the present utility model is discharged had not both had reeky white cigarette (a large amount of steam during humidity discharging are absorbed by the accumulation of heat of kiln body air channel), did not have billowing black smoke yet, and presentation loses the flue gas color, becomes tangible characteristic of environmental protection of kiln for this reason.
