Description
Technical field
The utility model relates to VOCs oxidation equipment field, is a kind of deflector type catalyst oxidation reactor that can realize efficiency utilization precious metal catalyst.
Background technology
At present, method mainly direct oxidation combustion method and catalytic oxidation that industrial VOCs extensively adopts is processed.Direct oxidation combustion method needs temperature higher than 650 degrees Celsius, and energy consumption is higher, and VOCs can not burn completely simultaneously, and assisted reaction can produce NOx, CO and other harmful hydrocarbons; The principle of catalytic oxidation process VOCs be to use catalyst make VOCs be heated to a certain degree low temperature time just can be converted into CO
2and H
2o, temperature is generally 200-300 degrees Celsius.The ubiquitous technical matters of current low-temperature catalytic oxidation equipment have: system component devices is complicated, comprises heat-exchange system, heating system, reaction system etc.; Gas needs fully to contact with catalyst just can reach desirable reaction effect, so cause system bulk large, and poor heat stability, energy consumption is high; System space huge structure, temperature distributing disproportionation, not exclusively, precious metal catalyst local heating affect reaction effect in reaction, reduction catalyst service life.
Summary of the invention
The purpose of this utility model is to provide a kind of catalyst oxidation reactor, and its floor space is little, precious metal catalyst consumption is few, utilization rate is high, be easy to replacing; Meanwhile, can a large amount of high concentration VOCs of efficiently catalyzing and oxidizing.
A kind of deflector type catalyst oxidation reactor, integrated equipment, comprise catalyst oxidation reactor, this reactor monolith is the tower structure of hollow, also comprise exhaust gas inlet, gas vent, distribution device, it is characterized in that: also comprise exhaust gas heating system, exhaust gas heating system connects the heat exchanger extending catalyst oxidation reactor inside by pipeline; 3 pieces of deflection plates are respectively set about catalyst oxidation reactor inside, at the precious metal catalyst of each deflection plate bottom even coating layer; Temperature control heat patching device is provided with in reactor wall between neighbouring each deflection plate.
Described deflection plate is interspersed in the reactor left and right sides, becomes 45-60 degree angle with tower wall.
Described precious metal catalyst is palladium platinum catalyst.
The utility model has the advantage of: (1) utilizes precious metal palladium platinum catalyst to carry out catalytic oxidation, realize low-temperature catalytic oxidation process VOCs, catalytic oxidation performance is high, and catalytic oxidation temperature requirement is low.(2) the utility model relate to equipment catalytic oxidizer collecting exchanger, gas heater, catalytic reactor in one, belong to integrated oxidation equipment, device structure is simple, and floor space is little.(3) the utility model is mainly hollow tower structure, built-in deflection plate, noble metal catalyst is coated bottom deflection plate, save noble metal catalyst consumption, extend gas and catalyst contact time, save space reactor again, compact conformation simultaneously, is easy to control temperature of reaction system even, and noble metal catalyst extends service life, utilization rate is high, and reaction efficiency is high.(4) noble metal catalyst is spread evenly across bottom deflection plate, and deflection plate quantity is 6 pieces, can according to catalyst performance, selective replacing, is easy to operation.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
The integrated equipment of a kind of deflector type catalyst oxidation reactor, comprise catalyst oxidation reactor 6, this reactor monolith is the tower structure of hollow, and comprise exhaust gas inlet 1, gas vent 9, distribution device 2,8, reactor is tower-like.Bottom is exhaust gas inlet and waste gas heater 4, tower inside is hollow-core construction, left and right respectively arranges 3 pieces of deflection plates 7, and at the precious metal catalyst 10 of each deflection plate bottom even coating layer, its effect is that catalytic oxidation VOCs becomes CO under certain lower temperature
2and H
2o.Deflection plate is interspersed in the reactor left and right sides, becomes 45-60 degree angle with tower wall, with ensure waste gas from reactor bottom heating after in the mode of baffling by reactor, finally give vent to anger from top.Temperature control heat patching device 3 is provided with in reactor wall between neighbouring each deflection plate, thermal source is provided by waste gas heater, its effect utilizes waste gas heater thermal source heat energy, by heat exchanger 5 heat exchange, ensures that reactor temperature atmosphere controls at 200-300 degree Celsius.After waste gas heating, baffling is by reactor, and fully contact with noble metal catalyst, VOCs is finally oxidized to CO
2and H
2o, is discharged by reactor top.
