Honeycomb activated carbon Generally, it is divided into waterproof type and ordinary type. There are great differences between the two types in terms of processing technology, microstructure, price, usage, etc. In order to better understand the honeycomb Activated carbon Next, we will introduce the difference between honeycomb activated carbon waterproof type and ordinary type and the selection method of pore size.
The pore size distribution of honeycomb activated carbon is generally divided into 50 holes, 100 holes and 150 holes according to the number of pores per inch, that is, there are 50 holes, 100 holes and 150 holes in a square inch unit.
The pore diameter of 50 hole honeycomb activated carbon is generally about 3-4mm, which is suitable for the exhaust gas with large air volume and large exhaust gas particles. The use of this large hole honeycomb activated carbon in high air volume and macromolecular exhaust gas will not affect the purification effect, which can be assured, and will also increase the contact area with exhaust gas.
The honeycomb activated carbon with 100 holes is a commonly used specification, and the use environment of this specification is relatively concentrated. Then there is 150 hole honeycomb activated carbon, which is suitable for small air volume and small molecule exhaust gas environment. Therefore, regardless of the pore size of honeycomb activated carbon, it must be used in the right place to play its advantages.
In waste gas treatment, the commonly used pore size of honeycomb activated carbon is divided into three types: large pore, medium pore and small pore. Large holes are 5mm and 400 holes, with small wind resistance and fast filtration speed; The middle hole is 3mm and 625 holes, with moderate wind resistance and filtration speed; Small holes are 1.5mm and 1600 holes, which have good use effect and are commonly used.
100 holes/square inch is a conventional specification that we usually use. This specification is used in a concentrated environment. That is, 150 holes/square inch is mainly used in small air volume and small molecule exhaust gas environment. The three above are the specifications of three kinds of honeycomb holes of honeycomb activated carbon. Customers can choose according to the environment of exhaust gas engineering, which can improve the purification effect, It can also solve the problem of large ventilation resistance.
