Abstract

The invention provides honeycomb activated carbon with a good purification function. The honeycomb activated carbon is characterized by consisting of the following components in percentage by weight: 50 to 75 percent of activated carbon, 20 to 40 percent of silicate, 3 to 15 percent of negative ion powder, and 1 to 5 percent of nano TiO2 powder. The activated carbon is prepared by the steps of mixing, ball-milling, filter-pressing and drying, pugging, performing extrusion molding, drying and calcining. An air purifier which is prepared from the activated carbon comprises a shell; two ends of the shell are provided with an air inlet and an air outlet; the air purifier is characterized in that: three plane filter plates, namely primary filter cotton, a high-efficiency particulate air (HEPA) high-efficiency filter element, and a cellular activated carbon sieve are sequentially arranged in the shell from the air inlet to the air outlet; and the three plane filter plates are parallel to the planes of the air inlet and the air outlet; and a fan is fixed on a support arranged in the shell, and a rotation shaft of the fan is vertical to the plane filter plates.

Description

technical field [0001] The invention belongs to a household environment purification product, and in particular relates to a honeycomb activated carbon that can be used for indoor air purification or drinking water purification, a manufacturing method thereof, and an air purifier prepared by using the honeycomb activated carbon. Background technique [0002] The damage that indoor air pollution may cause to the human body cannot be ignored. According to relevant surveys, 72% of households in China have unqualified indoor air quality, and 111,000 people die each year due to indoor air pollution, reaching 304 people every day. The control of air pollution is urgent. Harmful substances in indoor air mainly include formaldehyde, benzene, radon, smoke and so on. [0003] The development of honeycomb activated carbon was first reported in Japan. It not only contains the original advantages of activated carbon, such as large specific surface area, unique pore structure, stable su...
