Charateristic of Catalyzer:
The Honeycomb ceramics, which is inpregnated with Honeycomb,is generally called Honeycomb Catalyzer.Compared with Ball Type Catalyzer,the Honeycomb type catalyzer enjoys its biggest advantage thatMost heavy merit little obstruction fluid, namely fluid pigeonhole and lower little through honeycomb catalyst, So while dealing with waste liquid, waste gas in the dynamic catalysis course of fluid and factory, Finish reducing and use in power who fluid send consume and run expenses while reducing.
Another merit of the honeycomb type catalyst is to wear and tear small. So long as installation firm, fill out real to can long run type catalyst honeycomb, The turbulance of the fluid because of the small and roundish thing of spherical catalyst , in addition the equipment is shaken , Give up the spherical catalyst of certain quantity of needing to add regularly, has not merely increased the trouble of operating, The material of a large amount of activation that and run off.
1)Using Scope:
With the increase of the automobile, the atmosphere pollution that the tail gas of automobile caused has been already more and more serious. Developed countries, such as U.S.A., Japan,etc. have already made the regulation of rigorouslying enforces of HC, CO, NOx content in the tail gas of automobile. In order to lighten the tail gas of automobile to the pollution of the atmosphere, as the countermeasure, adopt following two kinds of measures mainly. It improves engine improve itself so-called" machine epurate" terms engine; Second, at tail angry to make and set free place load onto catalysis reactor, angry to epurate to tail. The catalysis reactor is noble metal catalyst, such as a handful of platinum, Pd, rhodium,etc., or the catalyst relying mainly on rare-earth metal oxide, Flood it on the ceramic carrier of honeycomb , load it onto it in the system of exhausting of the engine , At catalysis promoter, at HCs in being angry tail,, NOx catalysis epurate and succeed nonpoisonous water, oxygen and carbon dioxide CO.
2)Purity for the Exhausted Gas of Natric Acid Factory:
Nitric acid factories that produce the 3500th ton daily eacheses discharge thing about the 34000th cubic meter /when,among them nitrogen oxide from 0. 08-0. 30%, the others are nitrogen oxygen and moisture,etc.. It is the brown red gas to oxidize the nitrogen two times, as soon as oxidize the nitrogen colourless and tastelessly , but extremely easy to oxidize into the carbon dioxide in the air. This kind of gas has strong amazing smell , when contain 300 ppms in the air, can cause the deadly bronchus pneumonia . In the past with absorbing, absorb , catalysis finish burning method removed the carbon dioxide, But the cost is relatively high. Adopt the honeycomb catalyst in recent years, make the nitrogen oxide and catalysis reducing agent react, Produce nonpoisonous nitrogen and water, has received very fine result.
3)Purity for the Smell of the Exhaused Gas:
Organic poisonous substance and stench materials in industries waste gases,can not with oxidize and have quality poisonous substance. Though can achieve the same purpose to burn with the flame directly, necessary temperature is often above 800 ??, Should consume a large amount of burning and expenses of equipment. Adopting the honeycomb type catalyst, its catalysis is burnt and react to generally goes on among 250 - 350 ??, Purification efficiency is high, there is little equipment investment. The heat or burning on a small quantity supplementarily that often retrieves through the hot permutater can make the oxidizing process go on smoothly .
The honeycomb type catalyst can also be in a lot of field application, such as petrochemical industry, chemistry, chemical industry,etc. besides using in above-mentioned every fields .
