Advantages of honeycomb activated carbon in waste gas treatment from dingxinda9's blog

Industrial waste gas emission has always been a major problem that plagues industrial production. At this stage, organic waste gas treatment methods are mainly divided into three categories: physical method, chemical method, and biological method, including adsorption, direct combustion, catalytic combustion, chemical oxidation, biological filter, etc. powdered activated carbon Treatment methods. my country mainly adopts isolation method, combustion method, absorption method, condensation method, adsorption method, etc. in the treatment of industrial waste gas in China, but each has its own advantages and disadvantages.

Exhaust gas condensation:

By lowering the temperature, the harmful substances reach a condensed state, and the harmful substances are transformed from a gaseous state to a liquid state and separated from the air to achieve the purpose of purification.

Advantages: It is stable and has high purification efficiency for condensed harmful substances, which is close to the adsorption effect of honeycomb activated carbon.

Disadvantages: A lot of energy and investment are required, and operation requirements are high.

Plasma catalytic oxidation:

Plasma collides with gas ions to cause breakage, which will eventually oxidize and degrade organic matter.

Advantages: operation spot inspection and wide use, suitable for low-concentration, toxic and harmful gases.

Disadvantages: In the face of toxic and harmful gases, they cannot be completely converted. There will be more other products in the conversion process, and the reaction process requires high energy consumption.

Honeycomb activated carbon adsorption device:

Using honeycomb activated carbon with multiple voids and excellent adsorption capacity of activated carbon, organic gas molecules can be adsorbed on the surface of honeycomb activated carbon to complete the purification process.

Advantages: The treatment effect is the best of several methods (the adsorption effect can reach more than 99%), and it has an effect on most gases, the operation is simple and the cost is low, and the operation and maintenance are very convenient.

Disadvantages: Limited adsorption capacity requires regular maintenance.

At present, my country's waste gas treatment methods are relatively limited, and waste gas treatment requires comprehensive consideration of cost, effect, investment, operation strength, and whether it will cause secondary pollution. Although honeycomb activated carbon needs regular maintenance, it is good for most gases The adsorption and purification effect fully meets the national standards, and is gradually accepted and used by many manufacturers. It is a new type of environmentally friendly adsorption material.https://www.granular-activated-carbon.com
