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
The present invention relates to a kind of modified function Material Field, relate in particular to a kind of fine perlite modified activated carbon vehicle exhaust desulfurizing agent and preparation method thereof.
Background technology
Along with scientific and technological development, the progressively construction of modernization industry, various chemicals are exploited, and have brought facility, simultaneously because chemicals has produced environment and the harmful material of human body, the problem that has also become people to have to face to people's life.
Current airborne pollutant is mainly the toxic and harmful producing in the gas that produces of industrial fuel burning, vehicle exhaust, production.It is mainly to contain a large amount of noxious materials in the sewage of industrial production discharge that water pollutes, and also has the sewage in people's life to produce a lot of harmful substances.In people's life, also have and many times need to remove toxin, such as air conditioning filter has a lot of bacteriums, toxin on the net, newly-decorated has the harmful substances such as formaldehyde, all needs to remove toxin.All remove at present toxin and often use adsorbent, mainly contain silica gel, activated alumina, active carbon, molecular sieve etc., also have in addition for certain compositional selecting absorption and the sorbing material of development.But the most adsorption capacity of these adsorbents is limited, need to study different adsorbents for different requirements, bring into play best effect.Meanwhile, find new raw material, to strengthen adsorption effect, cost-saving.
Summary of the invention
The object of the present invention is to provide a kind of fine perlite modified activated carbon vehicle exhaust desulfurizing agent and preparation method thereof.
