Before use, you need to remove the dust on the surface of the columnar activated carbon and do a good job of cleaning, otherwise the powder will affect the use effect, and the washing process will also affect the water quality.
In the simple cleaning work of columnar activated carbon, ordinary cleaning cannot clean the adsorbed material in the pores of columnar activated carbon. wanyang activated carbon factory Therefore, the general cleaning work cannot clean the columnar activated carbon. If necessary, it needs to be replaced to avoid saturation of adsorption and make the columnar activated carbon. Loses effect.
The amount of columnar activated carbon used for indoor adsorption is related to the indoor mask. Generally, the more the amount, the better the effect. The amount standard is determined according to the indoor square area, and generally does not exceed one-tenth of the indoor area.
When columnar activated carbon is used for indoor adsorption, it is necessary to pay attention to the adsorption effect regularly and determine the basis for replacing the columnar activated carbon.
When using a fish tank, if you use a medicine to treat fish diseases, you need to take out the columnar activated carbon in advance, because the columnar activated carbon will adsorb various impurities in the fish tank, so as not to affect the effect of the medicine.
If it is used to adsorb formaldehyde and other harmful gases inside the new house, it needs to be exposed to the sun frequently to volatilize the harmful substances in the pores. Because the columnar activated carbon can effectively adsorb harmful gases, but cannot be decomposed, only regular exposure can restore it The adsorption capacity of columnar activated carbon.
Only by fully understanding the columnar activated carbon can the ideal use effect be achieved and the adsorption capacity of the columnar activated carbon can be maximized.
In modern industrial gas purification, honeycomb activated carbon performs well, has low gas resistance and excellent treatment effect. bituminous coal activated carbon It is commonly used in industrial production gas treatment and some public places in life.
During the use of honeycomb activated carbon, regular drying treatment is required to maintain the adsorption capacity of honeycomb activated carbon. After exposure and drying, the adsorption capacity of the carbon is obvious, and it has a good impact on the service life of the carbon.
If honeycomb activated carbon is used in a humid environment, water molecules will destroy its structure, easily cause rupture, and may cause dissolution in serious cases, and water molecules will enter the pores of honeycomb activated carbon, causing blockage and affecting the adsorption effect of honeycomb activated carbon.
During use, honeycomb activated carbon will inevitably enter some water molecules or other volatile impurities. Regular drying treatment is carried out to expose the water molecules and volatile substances inside the honeycomb activated carbon to free up certain pores. Therefore, after drying treatment The adsorption capacity of honeycomb activated carbon has been significantly improved, and regular drying treatment can effectively extend the service life of honeycomb activated carbon.
In the process of use, the honeycomb activated carbon is dried regularly to better exert its excellent adsorption capacity.
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.
