Technical Field
The utility model relates to a firing equipment technical field, in particular to high concentration organic waste gas burner.
Background
The combustion method can respectively adopt a direct combustion method or a thermal combustion method according to the concentration of combustible organic matters in the waste gas.
(1) When the concentration of organic matter in tail gas or waste gas is high enough, it can be released by combustion of organic matter in waste gasWhen the heat quantity is continuously burnt, the waste gas can be treated by adopting a direct combustion method. In the direct combustion process. Organic matters in the waste gas are treated as fuel, and the final product of combustion is CO2、H2O and N2。
The combustion apparatus used in the direct combustion method may be industrial and domestic combustion furnaces such as boilers or domestic stoves; or may be a dedicated flare burner. When the tail gas is used as fuel of a civil stove, a tail gas cabinet is required to be configured so as to keep balance between the generation amount and the treatment amount of the tail gas. When the torch burner is used for treating organic waste gas, the torch burner is specially designed to ensure that the torch burner can completely burn organic matters in the waste gas basically when the gas quantity of the organic waste gas or the organic matters fluctuate.
(2) The thermal combustion method is called thermal combustion when the content of combustible organic matters in the waste gas is low, the waste gas cannot be combusted, or the heat released when combustible components in the waste gas are combusted cannot be continuously combusted, and additional fuel is required to maintain the combustion, and the organic matters in the waste gas play a role of auxiliary fuel during the thermal combustion and are also treated.
In the thermal combustion method, firstly, additional fuel is burnt to provide heat, then the waste gas containing organic matters is mixed with high-temp. gas to reach the combustion temp. of organic matters to initiate the combustion of organic matters in the waste gas, at said temp. the waste gas is retained for enough time to make the organic matters in the waste gas fully combust and decompose to produce harmless CO2And H2And O. The thermal combustion can be carried out in a common boiler or a combustion furnace, and can also be carried out in a special thermal combustion furnace.
The following conditions should be noted when using a conventional boiler or furnace for thermal combustion:
① the waste gas should not contain non-combustible components such as inorganic soot, which may deposit on the heat transfer surface to reduce efficiency and increase power consumption;
② the oxygen content of the waste gas should be adapted to the oxygen demand of the boiler combustion to ensure sufficient combustion, otherwise large molecular weight organic matters such as tar formed by incomplete combustion will adhere to the heat transfer surface to reduce the thermal efficiency.
It is difficult to sufficiently burn the organic waste gas with high concentration, so it is necessary to design a new combustion device to completely burn the organic waste gas with high concentration.
