example 1

[0014] Example 1: First soak the three inorganic mineral materials of attapulgite clay and sepiolite bonded to zeolite in 1% concentration hydrochloric acid solution, then rinse with pure water or clean water, dehydrate and then bake at 200°C Dry, and then they are pulverized to 800 mesh fineness in superfine pulverizing equipment respectively. Mix the activated ultrafine attapulgite clay or sepiolite and active ultrafine zeolite at a ratio of 1:10 after the above treatment, add water to polymerize and granulate, and make various particles that are beneficial to air circulation and material exchange. After being dried, it is mixed with granular activated carbon at a ratio of 1:2 to obtain the "ultrafine activated adsorption type indoor air purifier" referred to in the present invention.

example 2

[0015] Example 2: First, soak the three mineral materials of attapulgite clay, sepiolite clay and zeolite in 10% sulfuric acid solution, then rinse with pure water or clean water, dehydrate and then dry at 400°C. Then they were pulverized to a fineness of 2000 meshes in an ultra-fine pulverizing device. After the above-mentioned treatment, the active ultrafine attapulgite clay or sepiolite and active ultrafine zeolite are mixed in a ratio of 10:1, and water is added to polymerize and granulate to make various particles that are beneficial to air circulation and material exchange. After being dried, it is mixed with granular activated carbon at a ratio of 20:1 to obtain the "ultrafine activated adsorption type indoor air purifier" referred to in the present invention.

example 3

[0016] Example 3: First, soak the three mineral materials of attapulgite clay, sepiolite clay, and zeolite in a 5% concentration hydrochloric acid solution, then rinse with pure water or clear water, dehydrate and then dry at a temperature of 300°C. Then they are respectively pulverized to a fineness of 1500 meshes in an ultrafine pulverization equipment. Mix the activated ultrafine attapulgite clay or sepiolite and active ultrafine zeolite in a ratio of 1:1 after the above treatment, add water to polymerize and granulate, and make various particles that are beneficial to air circulation and material exchange. After being dried, it is mixed with granular activated carbon at a ratio of 10:1 to obtain the "ultrafine activated adsorption type indoor air purifier" referred to in the present invention.

Abstract

The superfine compound active adsorbing indoor air purifier is prepared through mixing attapulgite or sea-foam via activation and superfine processing, clay and zeolite in certain proportion, polymerization, pelletizing and stoving, and further mixing with granular active carbon in certain ratio. The air purifier has great specific surface area and rich and complicated molecular pores in the size matching molecules of benzene, toluene, xylene, formaldehyde, ammonia, radioactive radon and other pollutant, so that the harmful molecules are adsorbed in the purifier owing to van der Waals force and the air is purified.

Description

technical field [0001] The invention relates to an indoor air purifier, especially an air purifier for complex adsorption and purification for air pollution caused by modern buildings and interior decoration, and is also suitable for air purification in vehicles, ships and other vehicles. The invention belongs to the technical field of environmental protection, and specifically relates to an ultrafine activated composite adsorption type indoor air purifier. Background technique [0002] Modern urban residents spend about 80% of their time indoors and in vehicles, and various new building materials, building additives, and decorations have caused indoor air to be generally polluted. There are also relatively high concentrations of organic pollutants in vehicles such as cars and boats that are newly manufactured or newly modified or painted. [0003] The existing air purification device mainly plays the role of filtering suspended particles and sterilizing, but the purificati...
