CN104084134A - Ammonia scavenger modified after burning natural mineral - Google Patents

Abstract

The invention aims at providing an ammonia scavenger modified after burning natural mineral. For realizing the aim, the technical scheme adopted by the invention is as follows: a preparation method of the ammonia scavenger comprises the following steps: grinding fire coal slag, taking a certain amount of slag powder, adding 1-5mol/L hydrochloric acid solution, stirring and soaking for 8-24 hors on a magnetic stirring apparatus, washing by using clean water, placing the soaked solid substance in sodium chloride solution and then soaking for 12-24 hours, pouring out supernate, washing by using deionized water to neutral, drying at 105 DEG C, and bottling for later use to obtain the ammonia scavenger.

Description

A kind of ammonia remover of natural minerals burning post-modification

Technical field

The present invention relates to ammonia adsorbing domain, be specifically related to a kind of ammonia remover of natural minerals burning post-modification.

Background technology

Ammonia, inorganic compound, is gas under normal temperature, the gas of colourless irritant stench, soluble in water, when ammonia is water-soluble, amino molecule becomes a hydration ammonia with hydrone by Hydrogenbond, one hydration ammonia energy fraction is ionized into ammonium ion and hydroxide ion, therefore ammoniacal liquor shows alkalescent, the mucous membrane of energy skin ambustion, eyes, respiratory apparatus, people sucks too much, can cause lung swelling, thus dead.

Due to a large amount of generations of municipal sewage and industrial wastewater, and exhaust emissions, cause environment more and more to worsen.Situation day by day serious, causes control imperative.

Absorption method is to process a kind of important physical chemistry method of harmful in waste water and waste gas and difficult degradation pollutant, and active carbon is the most frequently used sorbing material, but due to lack of material, cost is higher, regeneration is difficult etc., and reason is restricted its application.Take industry and agricultural wastes is raw material, and preparation and exploitation are cheap, to replace active carbon be the important directions that sorbing material is studied to efficient adsorption material.

Summary of the invention

The ammonia remover that the object of this invention is to provide a kind of natural minerals burning post-modification, the lack of material existing to overcome prior art, the shortcoming that cost is high.For achieving the above object, the technical solution used in the present invention is as follows:

Coal furnace ground-slag is broken, get a certain amount of pulverized slag, the hydrochloric acid solution that adds 1-5mol/L stirs and soaks 8-24h, then rinses with clear water on magnetic stirring apparatus, then soaked solid matter is put into sodium chloride solution and soak again 12-24h, pour out supernatant, extremely neutral with deionized water rinsing, 105 ℃ of oven dry, bottle standby, obtain this ammonia remover.

In the present invention, there is following distinguishing feature:

(1) invent described ammonia remover, raw material sources are extensive, cheap;

(2) invent described ammonia remover preparation method simple, adsorption rate is high;

(3) invent the stable performance of described ammonia remover, the life-span is long, can preserve for a long time use.

the specific embodiment:

Embodiment 1:

Coal furnace ground-slag is broken, take 100 g flyash, add 10% phosphoric acid solution 2L, under room temperature, flood 3h, then dry.After dry, solid matter is risen to the 300 ℃ of insulation 2h of temperature that pre-set from room temperature, be cooled to room temperature, take out end product and be washed with distilled water to neutrality, dry, bottle standby, obtain this ammonia remover.

Embodiment 2:

Coal furnace ground-slag is broken, take 100 g flyash, add 30% phosphoric acid solution 2L, under room temperature, flood 12h, then dry.After dry, solid matter is risen to the 500 ℃ of insulation 2h of temperature that pre-set from room temperature, be cooled to room temperature, take out end product and be washed with distilled water to neutrality, dry, bottle standby, obtain this ammonia remover.

Embodiment 3:

Coal furnace ground-slag is broken, take 100 g flyash, add 50% phosphoric acid solution 2L, under room temperature, flood 24h, then dry.After dry, solid matter is risen to the 700 ℃ of insulation 2h of temperature that pre-set from room temperature, be cooled to room temperature, take out end product and be washed with distilled water to neutrality, dry, bottle standby, obtain this ammonia remover.

Claims (1)

1. the ammonia remover that the invention discloses a kind of natural minerals burning post-modification, for achieving the above object, the technical solution used in the present invention is as follows:

Coal furnace ground-slag is broken, get a certain amount of pulverized slag, the hydrochloric acid solution that adds 1-5mol/L stirs and soaks 8-24h, then rinses with clear water on magnetic stirring apparatus, then soaked solid matter is put into sodium chloride solution and soak again 12-24h, pour out supernatant, extremely neutral with deionized water rinsing, 105 ℃ of oven dry, bottle standby, obtain this ammonia remover.
