Incineration method is the organic compounds in wastewater under the condition of high temperature, oxidation reaction occurs, the
resulting in carbon dioxide and water vapor.The north China already has such facilities at a factory in home, our country developed
two paragraphs furnace is introduced and two paragraphs furnace process, there are a lot of incineration facilities with sewage.
Incinerator is composed of two forms: one is pure incinerator, after burning exhaust emissions directly;The other is after the
incinerator with waste heat boiler, can generate steam.From energy saving point of view, a way of burning is good after using.
Early domestic incinerator is the gasification of coal gas, and the existing incinerator furnace station set is two pieces by
gas ignition, light oil ignition, and finally by the tar as the main fuel (electrical tar light oil production technology of the
second device in addition to the light oil, tar is electrical tar instrument in addition to the production technology level of
the heavier quality under the oil).Is the compound burner nozzle used, namely the burner in steam jet injection of phenol tar
and water spray, can achieve complete combustion inside the chamber of a stove or furnace, if the temperature is too low, or
atomization effect is not good, may cause product oil in the hearth, at the same time due to incomplete combustion of tar,
combustion gas can cause secondary pollution of the atmosphere.
This method is characterized by: simple technology, convenient operation.But its drawback is that energy consumption is larger,
the burning of water volume is small, its tar still can meet, or even use the self-produced vapor;Careless operation, the
temperature drop or water temperature is too large will cause the secondary pollution of the atmosphere. |
