Embodiment Construction

[0011] An expanded perlite modified activated carbon vehicle exhaust desulfurizer, made of the following raw materials in parts by weight (kg): activated carbon 110, tricalcium aluminate 6, tetracalcium aluminoferrite 5, dolomite clay 9, montmorillonite clay 8. Expanded perlite 17, calcium hydroxide 14, wood fiber 17, modified diatomite 4, appropriate amount of water;

[0012] The modified diatomite is made from the following raw materials in parts by weight (kg): diatomite 106, medical stone 33, nano-carbon 1.4, ascorbic acid 1.5, barley oil 1.6, sodium dodecylbenzenesulfonate 1.5, Zinc gluconate 2.5, dandelion powder 2.4; the preparation method is to put diatomaceous earth and medical stone into a calciner and calcinate at 550°C for 3.4 hours, take it out, soak it in 15% hydrochloric acid solution for 4 hours, filter it out, Repeated washing with clean water, drying, adding to water, at the same time, adding nano-carbon, ascorbic acid, zinc gluconate, grinding to obtain a sl...

Abstract

The invention discloses an expanded perlite modified activated carbon automobile exhaust desulfurizing agent which is prepared from the following raw materials in parts by weight: 100-120 parts of activated carbon, 5-7 parts of tricalcium aluminate, 4-6 parts of tetra calcium aluminoferrite, 8-10 parts of dolomite clay, 7-9 parts of montmorillonite, 15-20 parts of expanded perlite, 12-16 parts of calcium hydroxide, 15-20 parts of wood fiber, 4-5 parts of modified diatomite and a suitable amount of water. According to the expanded perlite modified activated carbon automobile exhaust desulfurizing agent disclosed by the invention, the expanded perlite is used for modifying the activated carbon to form loose porous powder, so high adsorption speed and larger adsorption amount are realized; quick and efficient desulfuration as well as longer effect can be realized by using tricalcium aluminate, tetra calcium aluminoferrite, dolomite clay, montmorillonite clay and calcium hydroxide as a desulfurizing agent. The expanded perlite modified activated carbon automobile exhaust desulfurizing agent disclosed by the invention has the advantages of low cost, simple technique, less environmental pollution, high desulfuration speed, easiness for regeneration, and suitability for high-concentration desulfuration of automobile exhaust and the like.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to an expanded perlite modified activated carbon automobile exhaust desulfurizer and a preparation method thereof. Background technique [0002] With the development of science and technology and the gradual construction of modern industries, various chemicals have been developed and utilized, which has brought convenience to people's lives. The problem. [0003] At present, the pollutants in the air are mainly the gas produced by industrial fuel combustion, automobile exhaust, and toxic and harmful gases produced in production. Water pollution is mainly due to the fact that the sewage discharged from industrial production contains a large amount of toxic substances, and the sewage produced in people's daily life produces many harmful substances. There are many times in people’s lives that people need to remove toxins. For example, there are many bacteria and toxins on...
