Description
Technical field
The present invention relates to reduce or eliminate the method and apparatus of noxious gas emission.The gas that pollutes is decomposed, cleans and neutralizes.The present invention be more particularly directed to be applicable to other that global warming gas and other are difficult to decompose.These gases comprise perfluocarbon (PFC), tetrafluoromethane (CF
4), perfluoroethane (C
2F
6) and the global warming and the greenhouse gases of many other ozone layer depletions.The present invention also can be by removing arsenous hydricde (AsH
3) or phosphine (PH
3) wait gas, thus be used for decomposing the decomposition of semiconductor technology exhaust jet stream.The gas that cleans, neutralizes and decompose these types needs high temperature.
Background technology
Existing system can not provide enough heat effectively to remove the global warming gas of discharging in the air-flow.Gas cleaning systems in the past comprise controlled decomposition/oxidation (CDO) and other.These Previous System effectiveness of performance are low, and downtime is long during the maintenance of equipment.In industry, as semi-conductor industry, there is huge demand in the gas cleaning systems, thereby meets the laws and rules of environmental emission.
Used heater in the existing gas cleaning systems.But, heater can not heat all gas fully, and heater is dirty, can not effectively transmit heat.They also can't bear the heavy load to granular pollutant or product, pass freely through cleaning systems thereby influenced gas.The regular cleaning of heater and cavity is necessary, thus the action of the halt system of having to perhaps treatment facility is taken down from production line, this just needs to connect a system and more cost.If these systems are not cleaned, then contamination gas cognition emits.
Therefore, need improved equipment and system, be used for the processing method and the equipment of dusty gas, with the purge heater compartment.Also need improved equipment and system, be used for neutralizing, the gas and the waste gas of removing and cleaning chemistry technology.Also need improved system, its can be effectively in and the gas, harmful constituent and the pollutant that discharge in the chemical technology.This system should guarantee to finish or finish substantially the neutralization and the removing of any dusty gas in the air-flow.It is simple and cheap also needing this system, is easy to build and operation, does not need fuels sources during operation.Needed system wants and can handle the air-flow that contains dusty gas by per minute, wherein the volume content of dusty gas from trace to tens to several hectolitres.
Summary of the invention
Summary of the invention
The invention provides a kind of by fuel gas is being elevated to autoignition temperature, it is carried out the equipment and the method for dynamic oxidation.This new invention rises to autoignition temperature with fuel gas, and contains the air of oxidant such as oxygen from almost vertical with fuel gas direction input.This method allows fuel gas to light automatically, and makes it carry out dynamic oxidation above under the situation of ambient oxygen voltinism gas, thereby realizes complete oxidation under the risk that does not have accelerated oxidation or blast.
This new invention comprises inflammable or flammable industrial waste gas merged, and is heated to above autoignition temperature (AIT), and the gas of heating is carried out dynamic oxidation, thereby makes gas carry out controlled burning.In this process, not (reality is not) of the gas of heating spontaneous combustion seemingly.
One hot cell heats the temperature that harmful waste gas flow to rising in a cavity, promptly between 600 ℃ to 1800 ℃, be preferably 900 ℃ to 1200 ℃, and until about 2000 ℃ or 2000-3000F, or higher, this moment, gas became spontaneous combustion.Hot gas spontaneous combustion when being exposed to air or other oxidizing gas.Air is laterally supplied with the air-flow of high heat and energy spontaneous combustion.The gas of heating can spontaneous combustion when touching air.The combustion product of rapid diffusion and the air of coming in produce disturbance, finish mixed process, and finish the burning of fuel gas.Excess air when disturbance mixes is guaranteed spontaneous combustion, and is reduced to the burning of the pyrophoric gas of finishing heat before not flammable in temperature.The waste gas stream completing combustion of heating has been guaranteed in disturbance.
By gravity and the machinery method of separating from the air inlet of heating, heating tube, final gas products and excessive air except that degranulation.Final oxidizing gas, combustion product and chilled gas carry out the separation of particle by the washer of gravity, cyclone separator, filter or cooling, and the combustion product of cooling is discharged by the blast pipe or the sprayer of cooling.
It in exhaust pure innocuous gas.
High temperature electrode in the waste gas heating chamber is rapid heat exhaust gases in oxygen-free environment.The heating of gas causes particle and charcoal to be adsorbed onto on the heating tube.Heating tube regularly scratches.The particle that scratches falls into jar.The final product that burns cools off in excessive air and cooling coil.
