Description

A kind of nanoscale concave convex rod molecular sieve processor for cleaning organic waste gas

Technical field

The utility model relates to VOCs treatment, especially a kind of nanoscale concave convex rod for cleaning organic waste gas point Son sieve processor.

Background technique

Traditional VOCs Treatment process generallys use active carbon adsorption technology, and this technology is by porosu solid adsorbent Organic exhaust gas is handled, it can make harmful components be forced to be adsorbed onto absorption under molecular attraction either chemical bond force effect The surface of agent, and then realize the purpose of purification treatment.But active carbon is by operative practice for many years, and there are some for the technique Apparent defect:

1) before mainly using absorbent charcoal material be used as adsorbent, and absorbent charcoal material using thermal current regenerate when peace Full property is poor, and when the temperature for regenerating thermal current reaches 100 DEG C or more, adsorbent bed is easy kindling.

2) regenerated carbon, because regeneration temperature is low, the part higher boiling after the completion of desorption cycles are purged using thermal current Compound cannot thoroughly be desorbed, and can accumulate in active carbon bed and decline its adsorption capacity.

3) usually active carbon has very strong water absorbing capacity, when waste gas humidity higher (more than 60%), to organic matter Detergent power will decline rapidly, and when handling the exhaust gas of high humility, the purification efficiency of bed is lower.

4) continuous and effective adsorption time is too short, the 3-7 days active carbons that just must more renew can only be generally maintained, due to wanting Frequently replacement, it is not only troublesome, the cost of enterprise was not only greatly increased, but also increase the useless processing of object and secondary pollution；

5) really effective also only tens kinds, many toxic because activated carbon is narrow to the absorption " spectrum " of organic exhaust gas Organic exhaust gas cannot effectively adsorb.

In view of the problem present on, by being continually striving in recent years, China the raw art of VOCs Treatment process on Achieved breakthrough.It is Adsorption Concentration+nitrogen protection regeneration recovery technology adsorption recovery that China market is widely applied at present, should Technology is using the VOCs in solid adsorption material selection absorption exhaust gas, and the material of adsorption saturation is under nitrogen protection through elevated temperature desorption Process, and then it is recycled VOCs.The technique mainly includes pretreatment, adsorption section and desorption section etc., pretreated useless Gas enters in adsorbent equipment after adsorption cleaning through smoke stack emission, and hot nitrogen desorption and regeneration is used after adsorption saturation.Nitrogen protection regeneration Technology uses nitrogen as desorption gas and is imported into adsorption bed, purges to the adsorbent material bed of adsorption saturation, shape At the mixed gas of inert gas and organic gas, organic solvent, having after separation are recycled in cooling liquid to gas within the condenser Solvent is stored, and nitrogen circulation utilizes.Nitrogen desorption technology biggest advantage is that safety is good, avoids regenerated with hot air When active carbon kindling hidden danger；It is regenerated relative to vapor, water content is low in recovered solvent, easy to separate and purify and recycling benefit With.Nitrogen protection regeneration recovery technology can be used for the purified treatment containing high-boiling-point waste organic gas.Currently, VOCs Treatment process is usual It is related to the combination of above-mentioned multiple technologies technique, such as: Adsorption Concentration+combustion technology；Adsorption Concentration+condensing recovery technology；Deng from Daughter+photocatalysis composite purification technology etc..But its weakness for also having its fatal:

1) internal surface area of adsorbent is theoretically very high for the adsorption rate of organic exhaust gas than bigger, due to " polarity " The features such as, make in practical applications, adsorption effect will receive the influence of many factors, such as adsorbent self property, exhaust gas Type, exhaust gas properties and concentration etc., are affected significantly, and replacement in general 3 months is primary；

2) currently, global zeolite, using lapping mode, minimum particle size is in 140nm；

3) plus after combustion technology, not only input cost is high for the first time, and maintenance cost greatly improves；

4) it is also easy to produce secondary pollution；

5) condensing recovery technology, and same problem is added to generate；

6) add plasma+photocatalysis composite purification technology, be extremely difficult to ideal treatment effect.
