Description
Technical field:
The utility model relates to the device that is used for enamel-covered wire and the processing of relevant industries waste gas catalytic combustion, refers in particular to a kind of catalytic combustion system.
Background technology:
The waste gas of current enamel-covered wire and relevant industries generally adopts catalytic combustion to handle.Its basic principle is that the waste gas that will contain a large amount of solvents carries out flameless combustion by the effect of catalyst, produces a large amount of heat energy, simultaneously waste gas is changed into CO
2And H
2O.Because it is big that the characteristic of enamel-covered wire industry has determined that enamel wire drying oven waste gas has a gas flow, the concentration height, characteristics such as complicated component, dust content height, coating cloud are carried secretly, thorough difficult treatment, therefore the waste gas catalytic combustion device of current enamel-covered wire industry is when handling waste gas, have generally that catalyst is easily poisoned, service life is short, catalytic effect is poor, be difficult to reach discharging standards, and easily produce secondary pollutions such as NOx etc.
The catalytic combustion system that exhaust-gas treatment adopted in enamel-covered wire and relevant industries normally adopts multi-layer catalyst to pile up together at present.The catalytic combustion system of this kind structure exists equally that fresh air can not fully mix with solvent waste gas, the residence time of solvent waste gas in catalyst is short, efficiency of combustion is low, catalytic effect is difficult to be up to state standards, heat energy from waste gas can not make full use of and have drawbacks such as producing secondary pollution.
The utility model content:
The purpose of this utility model is, at above problem, by improving existing technology, provides a kind of catalytic combustion system.
For achieving the above object, the utility model adopts following technical scheme, a kind of catalytic combustion system, and it includes pretreating zone, high activated catalyst reaction zone and guarantees three conversion zones of reaction zone; Pretreating zone is positioned at the bottom of this device, the air mixer that it includes the heater that is provided with electrothermal tube and is arranged on heater top; The top of pretreating zone is the high activated catalyst reaction zone that is provided with catalytic bed; Being arranged on above the high activated catalyst reaction zone is the assurance reaction zone that is provided with catalytic bed equally, is provided with the waste discharge blower fan at the top that guarantees reaction zone.
The beneficial effects of the utility model are: adopted to include pretreating zone, high activated catalyst reaction zone and guarantee three conversion zones of reaction zone; Pretreating zone is positioned at the bottom of this device, the air mixer that it includes the heater that is provided with electrothermal tube and is arranged on heater top; The top of pretreating zone is the high activated catalyst reaction zone that is provided with catalytic bed; Being arranged on above the high activated catalyst reaction zone is the assurance reaction zone that is provided with catalytic bed equally, is provided with the catalytic combustion system of waste discharge blower fan at the top that guarantees reaction zone, and the conventional catalyst burner has the following advantages on year-on-year basis:
1. because waste gas and air can fully evenly mix, through catalytic combustion repeatedly, improved catalytic combustion efficient, the exhaust-gas treatment effect can be up to state standards preferably.
2. reduce the catalyst poisoning probability, the service life of improving catalyst.
3. temperature height behind the catalytic combustion reaches 700 ~ 800 ℃, cooperates high efficiency heat exchanger, can improve the heat energy utilization amount, reduces the heater energy resource consumption, reduces production costs.
3. this apparatus structure is reasonable, stable performance, reliable, and wide adaptability has advantages such as easy to operate.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural principle schematic diagram of the present utility model.
The specific embodiment:
See accompanying drawing 1, a kind of catalytic combustion system, it includes pretreating zone 1, high activated catalyst reaction zone 2 and guarantees 3 three conversion zones of reaction zone; Pretreating zone 1 is positioned at the bottom of this device, the air mixer 5 that it includes the heater 4 that is provided with electrothermal tube and is arranged on heater 4 tops; The top of pretreating zone 1 is the high activated catalyst reaction zone 2 that is provided with catalytic bed 6; Being arranged on above the high activated catalyst reaction zone 2 is the assurance reaction zone 3 that is provided with catalytic bed 6 equally, is provided with waste discharge blower fan 7 at the top that guarantees reaction zone 3.
Device is made up of three reaction zones: waste gas produces turbulent mixture at the absorption cleaning of pretreating zone 1 realization dust, coating cloud through air mixer 5 and air, forms negative pressuren zone; Simultaneously the organic matter pollutant component is produced the reaction of part gas-phase decomposition; Second district be high activated catalyst reaction zone 2 as main reaction zone, organic exhaust gas fully contacts with catalyst when the Catalytic Layer, under the effect of catalyst activity composition, organic substance poisonous in the waste gas carries out abundant catalytic combustion; The 3rd district is for guaranteeing reaction zone 3, and the organic exhaust gas that is not decomposed is resolved into harmless CO fully at this
2And H
2Purified gas such as O are discharged, and guarantee the completeness of exhaust-gas treatment.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
