Description
Technical field
The utility model relates to a kind of heat accumulating burner capable, at the surface layer that heat storage contacts with burning bed, adds the catalyst synergy, reduce the activation energy of reaction, reduce the temperature that responds, improve the waste gas conversion ratio, thereby save chemical reaction preheating energy consumption, belong to the energy-saving and emission-reduction field.
Background technology
Heat accumulating burner capable is applied to organic exhaust gas and handles and combustion furnace intake and exhaust energy-efficient treatment mechanism.Occur the reaction of discharging tail gas easily not exclusively, the organic exhaust gas conversion ratio has much room for improvement.The solution reacting furnace-e/or that normally extends, or improve reaction temperature, cause equipment occupation space big like this, energy consumption is higher.
Summary of the invention
The purpose of this utility model provides a kind of more efficient energy-saving treating apparatus, at the surface layer that heat accumulating burner capable contacts with burning bed, adds the catalyst synergy, reduce the activation energy of reaction, reduce the temperature that responds, improve the waste gas conversion ratio, thereby save chemical reaction preheating energy consumption.
Catalyst can be coated in the gas passage surface of heat storage such as honeycomb ceramic carrier, and it is fully contacted with organic exhaust gas that flows through heat storage etc.
Contain titanium dioxide in the catalyst, the energy of the photons such as ultraviolet ray that the higher burner of titanium dioxide absorption temperature sends during reaction produces activation, produces catalytic effect, and the organic exhaust gas reaction activity that is in contact with it is reduced, and reaction decomposes is faster; Organic exhaust gas reacts ignition rapidly because of initiation temperature is lowered before entering the combustion chamber, makes in the reaction bed time longer, and alternative original burner 2 ignition actions have also been saved fuel simultaneously; Burning back organic exhaust gas contacts and further reaction with the heat storage 3 that is coated with catalyst when entering the heat storage of the other end in the outflow combustion chamber if the fraction unreacted is arranged, and makes conversion ratio higher.
Handle at organic exhaust gas, catalyst usefulness transition metal such as cerium (Ce), lanthanum (La), titanium oxide, noble metals such as palladium, platinum can make the rapid combustion reactions of hydrocarbon such as CO, HC under the temperature more than 500 ℃.
The heat storage that is coated with catalyst only is placed in the surface layer that contacts with burning bed, can keep the thermograde of heat storage unaffected like this.The concrete thickness of heat storage that is coated with catalyst is decided according to actual engineering.
Titanium dioxide and transition metal oxide are abundanter in china natural resources, and price is not high, utilize like this that equipment cost increases few behind the present invention.
Titanium dioxide granule nanoscale granule, better effects if.
Description of drawings
Accompanying drawing is that waste gas passes through the heat accumulating burner capable schematic diagram.
Among the figure, 1 is air inlet, and 2 is burner, and 3 for scribbling the heat storage of catalyst, and 4 is heat storage, and 5 are the ventilation valve, and 6 is exhaust outlet.
The specific embodiment
The purpose of this utility model provides a kind of more efficient energy-saving treating apparatus, at the heat storage top of heat accumulating burner capable, adds the catalyst synergy, reduce the activation energy of reaction, reduce the temperature that responds, improve the waste gas conversion ratio, thereby save chemical reaction preheating energy consumption.
Catalyst can be coated in the runner outer surface of honeycomb ceramic carrier, and it is fully contacted with organic exhaust gas that flows through heat storage etc.
Contain titanium dioxide in the catalyst, the energy of the photons such as ultraviolet ray that the higher burner of titanium dioxide absorption temperature sends during reaction produces activation, the organic exhaust gas reaction activity that is in contact with it is reduced, decompose faster during discharging: organic exhaust gas reacts ignition rapidly because of initiation temperature is lowered during air inlet, make in the reaction bed time longer, fuel has also been saved in alternative original igniter effect simultaneously.
Handle at organic exhaust gas, catalyst usefulness transition metal such as cerium (Ce), lanthanum (La), titanium oxide, noble metals such as palladium, platinum can make the rapid combustion reactions of hydrocarbon such as CO, HC under the temperature more than 500 ℃.
The heat storage that is coated with catalyst only is placed in the top layer that contacts with burning bed, can keep the thermograde of heat storage unaffected like this.The concrete thickness of heat storage that is coated with catalyst is decided according to actual engineering.
Do concrete introduction with regard to heat accumulation type thermal oxidation system (RTO) below.
Heat accumulation type thermal oxidation system (Regenerative Thermal Oxdizer) is a kind of high efficiency Organic Waste Gas Pollution abatement equipment, and it is made up of ceramic heat-storing bed 4, automatic control ventilation valve 5, combustion chamber, burner 2 and control system etc.Its principal character is: the automatic control ventilation valve 5 of energy storage bed bottom links to each other with exhaust main with the inlet manifold respectively; Energy storage bed 4 will be held by the high-temperature gas heat that comes out in the combustion chamber and stay, and preheating enters the organic exhaust gas of energy storage bed by alternately commutation of reversal valve; Adopt 3,4 absorptions of ceramic heat-storing material, release heat; Oxidation reaction takes place in the combustion chamber in the organic exhaust gas that is preheating to uniform temperature, generates carbon dioxide and water, is purified.Simultaneously, utilize high temperature resistant, the characteristic fast, rapid heat dissipation of absorbing heat of combustion chamber thermal storage ceramic, reclaim clean waste heat and be applied to production process, the consumption of energy savings, the RTO heat recovery efficiency generally can reach more than 80%, now has been widely used in the waste gas pollution control and treatment field of industries such as electronics, automobile, application chemical industry, pharmacy.
Burner 2 generally on centre, combustion chamber or both sides, worked the thermal ignition effect that adds when chamber temperature does not reach in the past.3 of heat storages that are coated with catalyst are placed in the top layer that contacts with burning bed, and the effect because of catalyst when waste gas enters the combustion chamber can reduce initiation temperature, and premature ignition makes organic exhaust gas reaction time lengthening, and conversion ratio is higher; Burning back organic exhaust gas contacts and further reaction with the heat storage 3 that is coated with catalyst when entering the heat storage of the other end in the outflow combustion chamber if the fraction unreacted is arranged, and makes conversion ratio higher.
For the regenerative apparatus of high temperature furnace, air inlet can be an air, but in the exhaust with the clean material of some unburneds, can more thorough reaction when contact is coated with the heat storage 3 of catalyst.Catalyst adjusts according to concrete unburnt ingredient.
