Abstract

The invention aims to provide an adsorbing material prepared from fire coal cinder used as a principal raw material. In order to realize the purpose, the invention adopts the technical scheme as follows: the fire coal cinder is smashed, a certain amount of cinder powder is taken, 10-50% phosphoric acid solution is added, impregnation is carried out for 3-24 hours at room temperature, drying is carried out, after drying, the temperature of the solid matter is raised to the preset temperature of 300-700 DEG C from the room temperature and heat preservation is carried out for 2 hours, the solid matter is cooled to be the room temperature, and the final product is taken out, washed to be neutral with distilled water, dried and bottled to obtain the ammonia gas adsorbing material.

Description

A kind ofly take the sorbing material that coal-fired slag makes as primary raw material

Technical field

The present invention relates to ammonia adsorbing domain, be specifically related to a kind of sorbing material that coal-fired slag makes as primary raw material of take.

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 object of this invention is to provide a kind of sorbing material that coal-fired slag makes as primary raw material of take, 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, add the phosphoric acid solution of 10-50%, under room temperature, flood 3-24h, then dry.After dry, solid matter is risen to temperature (300-700 ℃) the insulation 2h pre-setting 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 sorbing material.

In the present invention, there is following distinguishing feature:

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

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

(3) invent the stable performance of described ammonia sorbing material, 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 sorbing material.

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 sorbing material.

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 sorbing material.

Claims

1. the invention discloses a kind of sorbing material that coal-fired slag makes as primary raw material of take, 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, add the phosphoric acid solution of 10-50%, under room temperature, flood 3-24h, then dry; After dry, solid matter is risen to temperature (300-700 ℃) the insulation 2h pre-setting 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 sorbing material.
