Abstract
A modified active carbon nitrogen-removing agent is characterized by being composed of following raw materials in parts by weight: 100 to 120 parts of bamboo carbon, 2 to 3 parts of vinyl acetate, 10 to 15 parts of polyethylene glycol, 3 to 4 parts of urea, 8 to 10 parts of modified attapulgite, and a right amount of water. The preparation method adopts urea, which is used to reduce nitrogen oxides and purify the air; adds polyethylene glycol and vinyl acetate to make the active carbon difficult to disintegrate; adds metal oxides such as lanthanum oxide, and the like to remove sulfur, and adds jade powder, which is beneficial for people's health; and the modified active carbon nitrogen-removing agent has the advantages of health, environment-friendliness, and improvement on environment.
Description
Technical field
The present invention relates to a kind of method of modifying of nonmetallic ore, relate in particular to a kind of modified activated carbon and denitrogenate 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 modified activated carbon to denitrogenate agent and preparation method thereof.
Technical scheme of the present invention is as follows:
Denitrogenate an agent, it is characterized in that being made by the raw material of following weight portion: bamboo charcoal 100-120, vinyl acetate 2-3, polyethylene glycol 10-15, urea 3-4, attapulgite modified 8-10, water are appropriate; The described attapulgite modified raw material by following weight portion is made: attapulgite 120-130, sodium carbonate 3-4, bauxite 5-6, vanadium boride 1-2, jade powder 3-4, ferrous sulfate 1-2, titanium sulfate 14-18, active carbon 12-14, medical stone 2-3, lanthana 1-2, chromium oxide 3-4, morpholine 1-2, water are appropriate; Attapulgite, bauxite, jade powder, active carbon are sent in calcining furnace, at 850-870 ℃, calcined 4-5 hour, take out, putting into suitable quantity of water grinds again, regulating lapping liquid pH value is 4-5, grinds 1-2 hour, obtains 100-150 order slurry, regulate again lapping liquid pH value for neutral, add other residual components, continue to grind, obtain 200-300 order slurry, spraying is dry, obtains.
Described modified activated carbon is denitrogenated the preparation method of agent, it is characterized in that comprising the following steps: bamboo charcoal, vinyl acetate, polyethylene glycol, urea are mixed, join in suitable quantity of water, be heated to 80-90 ℃, after stirring, add attapulgite modified, grind to form 200-300 order slurry, then, spraying is dry, send in 320-350 ℃ of heat-treatment furnace and process 3-4 hour, obtain.
Divide the beneficial effect of the invention
The present invention has used urea, can nitrogen oxides reduction, purify air; By adding polyethylene glycol, vinyl acetate to make not easy disintegrating of active carbon, be easy to reclaim, can not discharge harmful substance; By adding the metal oxides such as lanthana, can desulfurization; The materials useful to human body such as jade powder have also been added; Health environment-friendly, improves environment.
