Abstract
The present invention provides a harmful gas removing agent, in which the acom extract can be contained, and the fruit kernel extract also can be selectively contained. Itis obtained by using alkali, kaolin and brine, etc., making them produce reaction and making extraction, then adding alum, loess and acid to make neutralization so as to obtain the invented product. It also provides its preparation method including the steps of pulverizing solid raw material, mixing, heating and filtration, etc.
Description
Technical field
The present invention relates to a kind of harmful gas scavenger and preparation method thereof.
Technical background
Along with the fast development of World Economics, the environmental problem of bringing is on the rise, and the ecological balance is destroyed.After particularly a large amount of urbanization, for example a large amount of dischargings such as sulfur dioxide, nitrogen-containing compound and carbon monoxide of various pernicious gases cause atmosphere pollution, acid rain occurs, make various diseases popular, bring very big harm to human survival.
Therefore, removing pernicious gas in order to environmental protection, is the important goal of current various countries.For this reason, many scientists have made extensive work, and obtain not little progress.For example Korea S Mr. Li Xiangtai studied for three more than ten years to CO gas antidote, obtained very big achievement.
The medicine that utilized a kind of prevention of the mixed preparation of aqueous acetic acid and ammoniacal liquor and treatment CO to poison in 1974, and carry out animal and clinical testing by Han Yang University professor LiBing Xi, think that this medicine can increase the erythrocyte number and the blood volume of animal and human's body, hemoglobin (CO-hb) in conjunction with CO is decomposed rapidly, guarantee that the quantity of free hemoglobin earns a bare living.This achievement has obtained universally acknowledged, and international blood association is in 23-29 day in July, 1978 and 17 and 18 sessions held respectively at Paris and Canada 18-22 day in August, 1980, and he has done the emphasis report.This achievement has also been declared patent, i.e. KR1978006727.But prevention that this product can only be used to poison and treatment can not be removed pernicious gas.
Through research for many years, on the original formulation basis, add various kernels such as almond or peach kernel and refine, obtain in a kind of product energy and pernicious gas, not only to CO, and to SO
2Also very effective.This product has obtained patent, and " pernicious gas nertralizer composition " by name sees KR1989029223.Improved work afterwards again in a large number, in the preparation method, added quick lime and mineral matter, and made this product SO
2Clearance rate reach 90.9%, see the KR1990036795 patent.Relevant patent is many in addition, KR1987006151 for example, and KR1990004940, KR1995000022 or the like, but all do not disclose a kind of harmful gas scavenger that from acorn nut, extracts, and this scavenger is to CO, SO
2And nitrogen oxide is all very effective.The present invention is the further improvement to patent KR1990036795, and its content this paper is in conjunction with quoting.
Summary of the invention
Therefore, the invention provides a kind of harmful gas scavenger, this scavenger is to CO, SO
2And nitrogen oxide is all very effective.The present invention also provides a kind of preparation method of harmful gas scavenger.
Scavenger provided by the invention contains the acorn nut extract, contains the kernel extract alternatively, and it is by alkali, kaolin, and reaction such as salt solution is extracted, and adds alum then, and neutralizations such as loess and acid obtain.
The preparation method of harmful gas scavenger provided by the invention comprises that with the solid feed pulverizing with alkali and salt solution and the mixed heating of distilled water, the gained reactant is further fully mixed with alum, loess and acid etc., and filtration obtains product.
Acorn nut is mainly similar with the extraction of alkali extraction and kernel, in order that do not destroy active ingredient wherein.Solid feed need be pulverized so that extract easily, and grinding particle size is not had strict restriction, and too thick granularity can be unfavorable to extraction efficiency, and there is no need to increase and grind cost and make granularity too thin, generally preferably approximately about 100 orders.Extract the back with neutralizations such as acid, make product keep neutral substantially, for example pH=6.5-8.Adding salt solution and kaolin when extracting is to extract smoothly in order to allow, and can make active ingredient have high-load.The alkali that uses during to extraction does not have strict restriction, and organic or inorganic alkali all can.Be preferably in and carry out in the weakly alkaline solution avoiding poly-injury acorn nut extract, therefore available ammonium salt, subcarbonate, ammoniacal liquor etc., wherein preferred ammoniacal liquor.Extracting temperature can not be too high, otherwise can destroy active ingredient; But temperature is crossed the low production efficiency that then influences.General preferred 200-300 ℃.Reacted product alum, loess and acid neutralization add alum and loess neutralization reaction is carried out under mild conditions used, so that obtain good result.Alum mainly is alum (AlK (SO
4)
2) and aluminium ammonium alum (AlNH
4(SO
4)
2).Preferably use organic acid, monocarboxylic acid or polybasic carboxylic acid, acetic acid for example, formic acid, propionic acid, oxalic acid, uncle's butyric acid, succinic acid or the like; Wherein preferred acetic acid cheap and easy to get.
The weight ratio of acorn nut and alkali about 1 during extraction: 1-1.5, acorn nut and kaolin weight ratio about 1: 2-3, the weight ratio about 1 of acorn nut and salt solution (HCl): 1.5-2, temperature reaction behind the adding distilled water.Obtain denseer product if desired, need not to add many distilled water; Otherwise, if the product that is directly used can add more distilled water.Along with what of distilled water, the ratio of each raw material and temperature can suitably be cut down according to the circumstance, and this is that those skilled in the art can access with basic experience.The 30-70 of the general preferred acorn nut grain weight amount of the addition of distilled water doubly.
In and the time, the weight ratio of acorn nut and alum about 1: 3-4, acorn nut with acid weight ratio about 1: 1-1.5, with the weight ratio of loess about 1: 0.8-1.2.
Further specify the present invention below in conjunction with embodiment, certainly, the present invention only limits to following examples absolutely not.

| Pilot project | Time | Concentration (ppm) | Clearance rate (%) | Remarks |
| NO 2 | Initial concentration | 60 | - | Detector tube NO.10 |
| 5 minutes | 5 | 91.7 | Detector tube NO.10 | |
| 10 minutes | 1 | 98.3 | Detector tube NO.9L | |
| 20 minutes | 4 | 97.1 | Detector tube NO.71 |
* 10:10 minute clearance rate is that clearance rate after 98.3%, 10 minute can't be measured because of the limit of detector tube.
