Description
Technical field
The present invention relates to a kind of combustion apparatus, particularly a kind of equipment of amine waste gas burning processing.
Background technology
With economic and industry fast development, atmosphere pollution getting worse, earth environment for the survival of mankind is made
Into great destruction.Combustion method processing organic exhaust gas generally has direct two kinds of combustion method and Production by Catalytic Combustion Process.Direct combustion method
It is that organic exhaust gas carries out oxidation reaction at 620~850 DEG C under high temperature, it is anti-to generally there are complete oxidation between 620~760 DEG C
It should be reacted with incomplete oxidation, the organic exhaust gas of complete oxidation is 60%~70%, and complete oxidation final thing is CO2With
H2O, incomplete oxidation reaction is oxygen-bearing organic matter and CO.As to purify as purpose method, such result is undesirable.
For temperature at 760~850 DEG C, exhaust gas conversion rate is 90%~95%, and when reaching 95%~99%, general temperature control exists
Between 850~1100 DEG C.Production by Catalytic Combustion Process is that organic exhaust gas is heated to 150~300 DEG C, is carried out in the presence of catalyst
Non-flaming combustion method.Temperature complete oxidation at 150~200 DEG C coexists with incomplete oxidation, and complete oxidation rate is 60%, remaining
For incomplete oxidation, at 250~300 DEG C, complete oxidation accounts for 90%~95%, and more than 300 DEG C reach 95%~99%.
The direct combustion method gas incinerator of prior art is mostly that waste gas is directly entered combustion chamber, or is mixed with air laggard
Enter combustion chamber, it is effectively not higher using the waste heat for exporting tail gas, energy consumption；And the structure of incinerator used in Production by Catalytic Combustion Process is often
It is that catalyst bed is arranged on combustion chamber, directly carries out catalysis burning, such structure causes the replacing and regeneration of catalyst
It is cumbersome.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of waste gas burning processing equipment, the device energy conservation, catalyst is more
Change simplicity.
The technical scheme is that：A kind of waste gas burning processing equipment, including gas inlet system, combustion system and cigarette
Chimney 9, the gas inlet system include blower fan 1, spark arrester 2, air inlet pipeline 3, hot gas line 4, and air inlet pipeline 3 passes through chimney 9
It is connected with the heat exchanger 7 in combustion system；The combustion system includes burner 5, combustion chamber 6, heat exchanger 7, catalyst bed 8；
The burner 5 is arranged on close to inlet end inside the burner hearth of combustion chamber 6, and described one end of combustion chamber 6 is provided with fuel gas and combustion-supporting sky
Gas import, the other end are connected with heat exchanger 7；Air inlet pipeline 3 is communicated by heat exchanger 7 with hot gas line 4, burner 5；Catalyst
Bed 8 is among heat exchanger 7 and chimney 9；Gas return path is：Blower fan 1 → spark arrester, 2 → air inlet pipeline, 3 → heat exchanger, 7 → hot gas
4 → burner of pipeline, 5 → combustion chamber, 6 → heat exchanger, 7 → catalyst bed, 8 → chimney 9.
The present invention provides a kind of novel device for waste gas burning processing, and tool has the advantage that compared with prior art：
1. whole system has two heat exchange points, first is after waste gas is collected by blower fan, by spark arrester, into air inlet
Pipeline is exchanged heat with smoke stack emission tail gas, and second gas for air inlet pipeline and combustor exit is exchanged heat, the two
The setting of heat-exchanger rig, the waste gas before making to enter combustion chamber realize two-stage preheating, and tail gas waste heat is fully used, and is reduced
Operating cost；
It is direct combustion reaction first 2. waste gas passes through two stages for the treatment of, is secondly catalyst combustion reaction, in waste gas by firing
Burning room is directly burnt after processing, is added a flameless catalytic combustion process again, is made not react complete waste gas component again
Secondary generation catalytic reaction, further cleaning of off-gas, greatly improves exhaust purification efficiency.
3. catalyst bed is arranged on outside combustion chamber, catalyst change is convenient, equipment easy disassembling.
Brief description of the drawings
Fig. 1 is the schematic diagram of waste gas burning processing equipment of the present invention.
Wherein：1. the heat exchanger of 6. combustion chamber of blower fan 2. spark arrester, 3. air inlet pipeline, 4. hot gas line, 5. burner 7.
8. the chimney of catalyst bed 9.
Embodiment
The present invention is elaborated below in conjunction with drawings and examples.
Embodiment 1
As shown in figure 1, waste gas burning processing equipment, including gas inlet system, combustion system and chimney (9).Waste gas enters
Gas system includes blower fan 1, spark arrester 2, air inlet pipeline 3 and hot gas line 4；Combustion system includes burner 5, combustion chamber 6, heat exchange
Device 7, catalyst bed 8.
The application method of the equipment is：First, waste gas enters equipment by blower fan 1, and air inlet pipe is entered after spark arrester 2
Road 3, waste gas carry out heat exchange with the tail gas in chimney 9 here, are further absorbed heat by heat exchanger 7 afterwards, pass through heating pipe
The burner 5 that road 4 enters in combustion chamber 6, reacts converging after-combustion with fuel gas with combustion air, and tail gas is by heat exchange
Device 7 carries out heat exchange with the waste gas in air inlet pipeline 3, the waste gas in air inlet pipeline 4 is further preheated, after heat exchange
Tail gas passes through catalyst bed 8, loaded catalyst is filled with catalyst bed 8, the complete waste gas of unreacted is in catalyst action
Lower generation secondary response, heat exchange, high-altitude are carried out with the waste gas in air inlet pipeline 3 in chimney 9 after reaching further purification
Discharge.
