1. Granular activated carbon is often used in gas phase adsorption, usually by allowing gas to pass through the activated carbon layer for adsorption. According to the state of the activated carbon layer in the adsorption device, the adsorption layer has several fixed layers, a moving layer and a flowing layer. However, in small adsorbers such as electric frosts and deodorizers in automobiles, adsorption by gas convection and diffusion is performed. In addition to granular activated carbon, activated carbon fibers and activated carbon moldings are also increasingly being used in gas phase adsorption.
2. The air in the instrument room, air-conditioned room, basement and submarine facilities often contains body odor, smoking odor, cooking odor, oil, organic and inorganic sulphide, corrosive ingredients due to external pollution or the influence of crowd activities in a closed environment. Etc., causing corrosion of precision instruments or affecting human health. It can be purified by activated carbon to remove impurity components.
3. Chemical plants, tanneries, paint factories, and engineering gases using various organic solvents contain various organic solvents, inorganic and organic sulfides, hydrocarbons, chlorine, oil, mercury, and other environmentally harmful The ingredients can be discharged after adsorption with activated carbon. The gases emitted from the atomic energy facilities contain radioactive cesium, strontium, iodine, etc., which must be adsorbed with activated carbon before being discharged. The flue gas generated by the combustion of coal and heavy oil contains sulfur dioxide and nitrogen oxides, which are harmful components that pollute the atmosphere and form acid rain. They can also be adsorbed and removed by activated carbon.
4. There are many use cases of coconut shell activated carbon for refined gas, such as gas masks, cigarette filters, refrigerator deodorizers, automobile exhaust gas treatment devices, etc., all of which utilize the excellent adsorption performance of activated carbon to make the toxic components in the gas unfavorable to the human body. The ingredients or odorous ingredients are removed. For example, after adding 100-120 ng of activated carbon to the cigarette filter, see Table 3-6-2, a large part of the harmful substances in the flue gas can be removed.
Coconut shell activated carbon application:
1. Desulfurized alcohol activated carbon: used as a carrier for a gasoline desulfurization (deodorization) catalyst in a refinery catalytic unit.
2, Vinylon catalyst activated carbon: used in the chemical industry as a catalyst carrier, such as vinyl acetate catalyst carrier.
3. MSG refined activated carbon: used for decolorization and refining of mother liquor in the production process of MSG, and can also be used for decolorization and refining of fine chemical products.
4. Activated carbon for cigarette filters: used in cigarette filters in the cigarette industry to eliminate toxic and harmful substances such as tar and nicotine in cigarettes.
5. Activated carbon for citric acid: used for decolorization, refining and deodorization of various acids such as citric acid, amino acid and cystine.
6. Activated carbon for direct drinking water treatment: Activated carbon is used for deep water purification in household direct drinking water, water treatment in tap water plants, and bottled water production.
7. Anti-virus and anti-chemical special environmental protection activated carbon: filter grid and military gas mask for filling various ventilation equipment.
Coconut shell activated carbon air purification use method:
1, even if there is even better air purification activated carbon products, people in the closed indoor time is too long, it is easy to cause some diseases. For the user, always pay attention to window ventilation, usually pay more attention to exercise. 2, the amount of activated carbon, the principle is the more the better, the greater the amount of use, the more harmful gases are adsorbed, especially in the home there are elderly or pregnant women more useful! But should consider the most suitable air purification carbon consumption from the economic aspect .
3. The emission of formaldehyde increases with the increase of temperature and humidity. In the case of humid and hot weather, that is, using activated carbon, the indoor formaldehyde concentration will rebound at this time, but don't worry, the air-purified activated carbon will return its adsorption to normal within a few days.
Coal columnar activated carbon is used for purification of toxic gases, waste gas treatment, purification of industrial and domestic water, and solvent recovery. And widely used in various aspects of industrial and agricultural production, such as the alkali-free deodorization (refined desulfurization), ethylene demineralized water (refined filler), catalyst carrier (palladium, platinum, rhodium, etc.), water purification and sewage treatment in the petrochemical industry; Water treatment and protection of power plants in the industry; chemical catalysts and carriers in the chemical industry, gas purification, solvent recovery and decolorization and refining of oils and fats; refining and decolorization of beverages, alcohols, MSG and foods in the food industry; gold in the gold industry Extraction, tail liquid recovery; environmental treatment industry sewage treatment, waste gas and harmful gas treatment, gas purification; and related industries, cigarette filters, wood floor moisture, odor absorption, automotive gasoline evaporation pollution control, preparation of various impregnating liquids Wait. Activated carbon will have excellent development prospects and a broad sales market in the future.
Main features of ceramsite filter:
1. The particles are round, uniform, rough surface, microporous, internal pores are developed, and the specific surface area is large, so that the adhesion of biological bacteria is strong, the reproduction is fast, the membrane efficiency is high, and the effect of removing ammonia nitrogen under low temperature and low turbidity conditions reaches the domestic advanced level. The working cycle is long, and the cycle water production is large, generally 500-1000 m/m.
2. The accumulation weight is light and the strength is high, so the backwashing energy consumption is low, the head loss is small, and the head loss of the cleaning material is only 150mm/m. 2. The accumulation weight is light and the strength is high, so the backwashing energy consumption is low, the head loss is small, and the head loss of the cleaning material is only 150mm/m.
3. Strong interception capacity, generally 9-13kg/m.
Ceramsite filter material application range:
In the treatment of steel rolling wastewater, precipitation, coagulation, and biological ceramsite filtration are generally employed. After the suspended solids and oil in the wastewater are removed, they are cooled and recycled. The water quality of the treated water requires a turbidity of 10-15 degrees and an oil content of 10 mg/liter.
Several representative systems for treating hot rolled wastewater are as follows:
A. Wastewater ~ iron pit, sedimentation tank, cooling tower ~ recycling.
B. Waste water ~ iron pit ~ coagulation sedimentation tank two cooling tower, recycling.
C. Wastewater ~ Tin pit ~ sedimentation tank ~ filter ~ cooling tower ~ recycling.
Some factories use hot metal pits to separate hot iron oxide skin and oil from the hot-rolled wastewater, and then use pressure ultra-high-speed bioceramics to filter and treat the water after cooling through the cooling tower. For the oily wastewater generated during the cold rolling process, the adjustment tank is generally used to remove most of the oil in the water, and then the emulsified oil is removed by coagulation and flotation. The oil content in the cold-rolled wastewater is about 200-300 mg 7 liters and the turbidity is 200-40 degrees. After the wastewater stays in the regulating tank for 30-60 minutes, the effluent oil content is about 10 mg/L. The effluent water after flotation treatment has an oil content of 10-30 mg/liter and a turbidity of 20-50 degrees. If it is subjected to secondary treatment, water with good water quality can be obtained.
