Abstract

The invention relates to the technical field of boiler waste gas purification and especially relates to a preparation method of an activated carbon filter screen shaping material. The method includes the steps of: 1) adding 25 parts of activated carbon, 5 parts of glass fibers, 5 parts of calcium hypophosphite and 10 parts of glycerol into a reaction container, and stirring the components at 1000 r / min at 50 DEG C for 20 min; 2) adding 25 parts of activated carbon and 5 parts of aluminum oxide into the reaction container, and stirring the components at 1500 r / min at 35 DEG C for 5 min; 3) adding 5 parts of glass fibers and 3 parts of paeonol into the reaction container, and stirring the components at 1250 r / min at 70 DEG C for 30 min to prepare a mixture powder, which is the activated carbon filter screen shaping material. In the preparation method, through reasonable selection on raw materials and ratios, a shaped activated carbon filter screen is significantly prolonged in service life, has good mechanical performance and is high in bearing strength.

Description

technical field [0001] The invention relates to the technical field of boiler exhaust gas purification, in particular to a preparation method of an activated carbon filter net forming material. Background technique [0002] When the boiler is working, the exhaust gas is discharged through the chimney, which contains a lot of dust and other harmful gases, especially when the combustion is insufficient, the billowing black smoke discharged is the coke solid particles of insufficient combustion. If these gases containing a large amount of dust and particles are directly discharged into the environment, they will cause great harm to the environment, and even cause various respiratory diseases for humans. [0003] People have adopted various exhaust gas purification equipment to treat boiler exhaust gas, but the existing boiler exhaust gas purification devices are usually complex in structure and high in cost, and are not suitable for boiler equipment of some medium and small ent...
