Description
Technical field
The present invention relates to a kind of organic waste gas catalytic combustion treating apparatus, belong to exhaust-gas treatment field.
Background technology
Catalytic combustion is by under catalyst at low temperatures (200 ~ 400 DEG C), realize organic complete oxidation, therefore, less energy consumption, easy and simple to handle, safety, purification efficiency is high, in the organic exhaust gas organic waste-gas purification that particularly recovery value is little, and such as chemical industry, spray paint, the sector application such as insulating materials, enamel-covered wire, coating material production is comparatively wide, the catalyst burnt due to current catalytic organism mostly is noble metal (based on platinum, palladium) catalyst.But because noble metal catalyst is expensive, resource is few, therefore, the research of more economical new catalyst becomes new developing way.
Summary of the invention
Technical problem to be solved by this invention is to provide the organic waste gas catalytic combustion treating apparatus that a kind of catalyst is cheaply easy to get; Further, provide a kind of and have protective effect to catalyst and the organic waste gas catalytic combustion treating apparatus of use safety.
For solving above technical problem, the technical solution used in the present invention is: a kind of organic waste gas catalytic combustion treating apparatus, comprise waste gas holding vessel, pretreatment unit, preheating unit and catalytic combustion unit, described catalytic combustion unit comprises fixed bed catalytic reactor, described fixed bed catalytic reactor comprises catalyst carrier and active component, described catalyst carrier is ceramic honeycomb, and described active component is rare earth oxide; Described discarded holding vessel is connected with pretreatment unit, and described pretreatment unit is connected with described preheating unit, and described preheating unit gas outlet is connected with the air inlet of described catalytic combustion unit, and the gas outlet of described catalytic combustion unit is connected with exhaust blower.
Described pretreatment unit is gas-filtering device.
Be in series with spark arrester one before the air inlet of described preheating unit, behind described catalytic combustion unit gas outlet, be in series with spark arrester two.
The air inlet place of described preheating unit is provided with gas concentration inspect device, and the air inlet of described preheating unit is connected with benefit air-cooler by three-way pipe.
The gas outlet of described waste gas holding vessel is connected with air inlet fan, and the gas outlet of described air inlet fan connects the air inlet of described pretreatment unit.
Described preheating unit is high-grade fuel burner or high temperature resistance silk.
The technological process using the present invention to carry out exhaust-gas treatment is: the organic exhaust gas in waste gas holding vessel enters pretreatment unit under the suction of air inlet fan, after pretreatment unit filters, remove dust, drop and catalyst poison wherein, to avoid blocking and the catalyst poisoning of beds; Waste gas after filtration, through spark arrester one, by gas concentration inspect device, when organic exhaust gas concentration likely exceedes controlling value, is opened benefit air-cooler and is watered down safety value; Gas after over-richness controls enters preheating unit heating, and the gas after heating enters catalytic combustion unit, in fixed bed catalytic reactor, carry out catalytic combustion, and the gas after burning enters air through exhaust blower again through spark arrester two.
Beneficial effect of the present invention is:
1. the rare earth oxide used is as catalyst, and rare earth enriches in china natural resources, has low price, the advantage that resource is easy to get compared with noble metal catalyst;
2. arrange pretreatment unit, the poisonous substance of dust, drop and catalyst in removing waste gas, avoids blocking and the catalyst poisoning of beds;
3. spark arrester is installed, propagation of flame when preventing organic exhaust gas from burning on beds, improves the security of equipment;
4. arrange gas controlling device and mend air-cooler, the concentration due to organic exhaust gas must control in less than 25% of corresponding organic matter explosion limit, when organic exhaust gas concentration likely exceedes this value, can be watered down safety value, the security of further raising equipment.
A kind of organic waste gas catalytic combustion treating apparatus provided by the present invention, adopt rare earth oxide in conjunction with the carrier of ceramic honeycomb as fixed bed catalytic reactor, Catalytic Combustion Effect is good, and material is cheaply easy to get; Be provided with pretreatment unit simultaneously, block and catalyst poisoning to prevent catalytic bed; And spark arrester, gas controlling device and benefit air-cooler are installed, improve the safety in utilization of equipment.Catalyst of the present invention is cheaply easy to get, durable security, is adapted at promoting the use of in VOCs treatment.
