Abstract
The invention discloses a modified volcanic rock dedusting adsorbent. The adsorbent is characterized by being prepared from the following raw materials, by weight part: 8-15 of calcium carbonate fiber, 20-40 of tetrabutyl titanate, 3-5 of silica sol, 6-8 of calcium aluminate, 60-80 of volcanic rock, 6-9 of PA nylon powder, 3-4 of gelatin, 1-3 of ammonium bicarbonate, 5-7 of acid white clay, 3-4 of copper oxide, and a proper amount of deionized water. Copper oxide and acid white clay added in the adsorbent improve properties, such as sterilization, decoloration, and adsorption, of the adsorbent, are high in adsorption efficiency, fast in speed, and large in capacity via a synergistic effect, and have preferable adsorption ability of various pollutants. The prepared adsorbent is simple in preparation technology and wide in adsorption range; the materials are green and environment-friendly; and the method is simple and easy to operate and convenient to popularize.
Description
Technical field
the present invention relates to a kind of absorbent fields, be specifically related to a kind of modification volcanic rock dedusting adsorbent and preparation method thereof.
Background technology
Along with the development of national economy, increasing industry emerges and drives economic fast development, and thing followed environmental problem is also day by day serious.The heavy industry such as cement, electric furnace often has a large amount of dust to discharge in process of production, has a strong impact on natural environment, and endangers the healthy of workman and surrounding resident.Also be mingled with a large amount of noxious vapors inside some dust, to the healthy of people and ambient influnence very serious.General enterprise can use sack cleaner, but belt dedusting is very easily fully loaded, can not clean absorption version timely and effectively, greatly affect adsorption efficiency, and can not adsorb toxic gas.
Volcanic rock quality is hard as lithotome, coating surface honeycomb porous, specific area is large, and soak change without exception in water, water proofing property is splendid, fire prevention, weather resisteant is good, can prevent the deterioration caused because of ultraviolet, have nontoxic, tasteless, intensity is high, heat insulation, acid and alkali-resistance, stain resistance, corrosion-resistant, resistance toly to go mouldy, and the advantage such as pollution-free, "dead", as sorbent material, there is good application prospect.Although adsorption rate and adsorption capacity are improved at present, but absorption after adsorbent and solvent not easily separated, the present invention adds magnetic material in sorbent material makes adsorbent can be good at being separated, sorbing material is made to carry out secondary cycle use, and excellent effect, and to toxic gas, dust, all there is good suction-operated, advantages of good adsorption effect, decrease the impact on people and environment of dust and toxic gas largely, be worthy to be popularized.
Summary of the invention
The object of this invention is to provide a kind of modification volcanic rock dedusting adsorbent and preparation method thereof.
In order to realize object of the present invention, the present invention is by following scheme implementation:
A kind of modification volcanic rock dedusting adsorbent, is made up of the raw material of following weight portion: calcium carbonate fiber 8-15, butyl titanate 20-40, Ludox 3-5, calcium aluminate 6-8, volcanic rock 60-80, PA6 nylon powder 6-9, gelatin 3-4, carbonic hydroammonium 1-3, Emathlite 5-7, cupric oxide 3-4, deionized water are appropriate;
A kind of modification volcanic rock dedusting adsorbent of the present invention, be made up of following concrete steps:
(1) absolute ethyl alcohol of butyl titanate and 3-4 times amount is mixed, magnetic agitation 1h, magnetic agitation 2h is continued again by being added in above-mentioned solution after short for calcium carbonate fiber cutting, slow dropping deionized water, continue after gel to be formed to stir 0.5-1 hour, then to be added in baking oven that under 80 ° of C, to dry grinding for subsequent use;
(2) spend deionized water after volcanic rock being soaked 12h in concentrated sulfuric acid and grind to form fine powder to neutral oven dry, then mix with gelatin, PA6 nylon powder, in Muffle furnace, under 240-255 ° of C, calcine 0.5-1h, take out after cooling;
(3) by the product of step (1) gained and except calcium aluminate all the other remaining material mixing and stirring, employing pressure is that mixture is pressed into bead by the ball press of 10t-20t, selects particle size for subsequent use as ball core at the bead of 5-15mm scope after screening;
(4) product of step (2) gained and calcium aluminate are mixed, the bead of step (3) gained is placed in disc balling machine as kernel, add above-mentioned volcanic rock mixture, rolling pelletizing, volcanic rock is covered on ball core and forms shell, the composite sphere of gained is calcined under 550-600 ° of C 2-4h and become porous complex microsphere.
Advantage of the present invention is: the present invention adopts calcium carbonate fiber to mix with TiO 2 sol, enhance the intensity of TiO 2 sol, bactericidal properties, the performance of the aspect such as adsorbance and heat resistance, adopt gelatin and PA6 to be added to define skeleton when calcining in volcanic rock and make Adhesion enhancement between volcanic rock, not easily be scattered when making adsorbent dry linting, wearability strengthens, extend service life, and double-layer porous road adsorption microspheres made by adsorbent by the present invention, enhance adsorption capacity and adsorption rate, to tiny field trash, there is good adsorption effect, expand adsorption range, the cupric oxide added and Emathlite enhance the sterilization of adsorbent, the performances such as decolouring and absorption, synergy adsorption efficiency is high, speed is fast, capacity is large, to various pollution, all there is good adsorption capacity, absorbent preparation technique prepared by the present invention is simple, adsorption range is wide, material environmental protection, method simple possible, be convenient to promote.
