Abstract
The present invention is fluid purifying matter, and is especially fluid purifying agent with zeolite as adsorbent. The technological scheme is that zeolite in 70-90 weight portions and granular combustible in 15-25 weight portions are mixed, the mixture is sintered at 800-1000 deg.c to burn out the combustible and form sintered zeolite with great amount of micropores. The zeolite adsorbent is used as fluid purifying agent to eliminate harmful matters effectively and the used zeolite adsorbent may be recovered for reuse.
Description
Technical field
The invention belongs to a kind of fluidic material such as purify air, specifically a kind of cleanser that utilizes zeolite as adsorbent.
Background technology
Zeolite (Zeolite) is the general name of zeolite family mineral, is a kind of alkali or alkaline earth metal aluminosilicate mineral of aqueous shape structure, and general chemical formula is AmXpO
2PnH
2O, wherein A is Na, K, Ca, Ba, Sr; X is Si, Al.Natural zeolite is a kind of brand-new material, is widely used in departments such as industry, agricultural, national defence, and its purposes is also in developing constantly.
Cleanser uses active carbon as adsorbent usually in the prior art, absorbs the harmful substance in air or the water.Though also report and can adopt zeolite as cleanser, only limit to the experimental stage so far, still there is not industrial applications.
Summary of the invention
The object of the present invention is to provide a kind of cleanser, this cleanser behind oversintering has a large amount of micropores, when being used for the cleanser of adsorbed gas or liquid, can effectively remove harmful substance wherein, and recyclablely is recovered utilization.
According to technical scheme provided by the invention, with the zeolite of 70～90 weight portions with after the graininess combustible of 15～25 weight portions mixes, through 800～1000 ℃ of sintering, behind sintering, the graininess combustible is because of the burning distillation, zeolite is sintered in bulk, and forms the micropore that forms because of the distillation of graininess combustible in a large number in block.
When mixed zeolite and graininess combustible, also add the beta cyclodextrin of 0.5～1.5 weight portion, to improve the adhesive property of mixture, unit micro weight percent.The granularity of zeolite and graininess combustible is 800～1000 orders.The graininess combustible is a kind of plant debris that produces when the processing plant; Described plant debris comprises one or more in wood flour, paper scrap, bamboo bits, the grass bits.
Zeolite is used as ion-exchanger, adsorption separating agent, desiccant, catalyst, cement additive.In oil, chemical industry, be used as chemical isomerizationization, reformation, alkylation, the disproportionation of catalytic cracking, hydrocracking and the oil of petroleum refining; Gas, liquid purify, separate and store agent; Water softening, seawater desalination; Special desiccant (dry air, nitrogen, hydro carbons etc.).Be used for papermaking, synthetic rubber, plastics, resin, paint fill agent and quality color etc. at light industry.In building materials industry, as cement hydraulicity active blending material, fire artificial lightweight aggregate, make light-high-strength sheet material and brick.At aspects such as national defence, space technology, ultrahigh vacuum technique, develop energy, electronics industries, as adsorption separating agent and desiccant.On agricultural,, can play a part to protect fertilizer, water conservation, prevent disease and pest as soil conditioner.In the fowl farm, make the additive of feedstuff (pig, chicken) and deodorizer etc., can promote the domestic animal growth, improve little adult livability.Aspect environmental conservation, be used for handling waste gas, waste water, from waste water and waste liquid, remove or reclaim metal ion, remove radioactive contaminant in the waste water.The zeolite of saturated activity material after the ion exchange can be used as radiation source again and uses.Can also from the waste gas of synthetic ammonia factory, reclaim ammonia, from the waste gas of sulfuric acid plant, reclaim SO
2, in addition, can also from other industrial waste gas, adsorb carbon monoxide and ammonia etc.
Ion exchangeable is one of critical nature of zeolite.Cation such as K, Na, Ca and hydrone combine not tightly with screen work in the cavity in the zeolite lattice (hole), very easily with its ambient water solution in cation generation exchange interaction, the zeolite lattice structure after the exchange is not destroyed yet.
Zeolite has very big specific surface area (500～1000 meter 2/ gram), thereby can produce bigger extension, so can be used as outstanding adsorbent.The zeolite intracell has a lot of uniform holes and passage, and the passage by opening between the hole is connected with each other, and links up with the external world.The volume of hole and passage accounts for more than 50% of zeolite crystal volume, wherein has many desorptions zeolite water freely.What of zeolite water can change with the temperature and humidity in the external world.
The hole of zeolite inside and passage under the certain physics chemical condition, have accurate and fixed diameter (about 3～11
), various zeolite, its diameter are also different, can be adsorbed by it less than the material of this diameter, then are left out greater than the material of this diameter.This phenomenon is called as " molecular sieve " effect.But be not that all zeolites can both play the molecular sieve effect.Some zeolite pore is too little, does not just have the effect of molecular sieve.Zeolite not only has the performance of adsorbed water, but also has adsorption and oxidation calcium, SO
2, F
2, nitrogen, ammonium, methanol and absorption radioactive substance performance.
Because the present invention has added the graininess combustible in natural zeolite, these graininess combustibles are volatilized behind sintering to be fallen, in zeolite, stay a large amount of micropores or minitype channel, these micropores or minitype channel are all greater than original hole of zeolite and passage, when air process cleanser of the present invention, air can successfully enter in micropore or the minitype channel, and venomous injurant mass-energy is wherein fully adsorbed to fall by hole and passage, and the purification efficiency of air is greatly improved.
After in zeolite, adding beta cyclodextrin, can effectively improve the bonding force of zeolite, make the zeolite behind the sintering have higher intensity.
