Problems solved by technology

Although the effect of this method is good, but because these oxidants do not have oxidation selectivity, they are easily consumed by non-odor-causing reducing substances, and there are problems such as short action time, frequent addition of agents, large spraying amount, and poor persistence.

Embodiment 1

[0085] A composition A for removing odor associated with ammonia and nitrogen compounds 2 , including by mass percentage: 80% of diethylene glycol (including auxiliary glycerol, glycerin accounts for 5% of its mass), 8.0% of oleic acid, 9.47% of zinc ricinoleate, 2,6-di-tert-butyl p-methyl 0.01% phenol, 0.01% sodium tetraborate, 0.5% coconut aldehyde, 2.0% sodium dodecylbenzenesulfonate, 0.01% octanol. The above-mentioned deodorant composition A 1 Raw material accounts for deodorant A 1 The mass ratio is 15%, and water accounts for 85%. All raw materials are industrial grade, and water is industrial purified water (the same below).

[0086] First, add water into the mixing tank (or reaction kettle), start the mixer, add each raw material of composition A in turn, stir at 55°C for 30 minutes to make it fully mixed, and the stirring speed is 80r / min. Cool the mixed material to below 40°C, put it into a high-shear device, and cut it at a shear rate of 20,000 r / min for 5 minut...

Embodiment 2

[0093] A composition A for removing odor associated with ammonia and nitrogen compounds 2 , including by mass percentage: propylene glycol 70% (including auxiliary glycerin, glycerin accounts for 5% of its mass), linoleic acid 15.0%, aluminum chloride 13.47%, vitamin E 0.01%, sodium benzoate 0.01%, lavender essence 1.0% %, AES 0.5%, silicone defoamer 0.01%.

[0094] The above-mentioned deodorant composition A 2 Raw material accounts for deodorant A 2 15% by mass, 85% by water.

[0095] The method of preparation and use is the same as in Example 1.

[0096] Table 2 test results show that deodorant composition A 2 The deodorant effect is better, but slightly lower than the deodorant composition A 1 , where for NH 3 The removal rate of 94.82%-96.02%, the removal rate of aliphatic amine compounds is 94.20%-96.02%, the removal rate of aromatic amine compounds is 91.98%-94.07%, and the removal rate of heterocyclic amine compounds is 94.62%-96.69%; mist spray and other quality...

Embodiment 3

[0101] A composition B for removing odor associated with ammonia and nitrogen compounds 1 , according to its mass percentage, including: citric acid 40%, glutamic acid 9.0%, FeSO 4 ·7H 2 O 0.4%, MgSO 4 ·7H 2 O 0.1%, sodium benzoate 0.01%, vitamin E 0.01%, Span-20 1.0%, coconut aldehyde 0.5%, water 48.98% (about 49%).

[0102] First add water into the mixing tank (or reaction kettle), start the mixer, and add composition B in sequence 1 Single raw material, stirred at 55°C for 30min at a stirring speed of 80r / min to make it fully mixed, cooled to below 40°C, put it into a high-shear device at a shearing speed of 20,000r / min, and sheared for 5min, that is Composition B for removing odors related to ammonia and nitrogen compounds 1 Mother liquor (referred to as deodorant composition B 1 ), put into barrels for later use. Dilute 10 times with tap water when using, and use mist spray method to remove odor.

[0103] The result shows (table 3), deodorant composition B 1 to N...

Abstract

The invention provides a composition for removing stink related to ammonia and nitrogen compounds, a preparation and application, and belongs to the technical field of harmless treatment and recyclingof solid wastes. The composition comprises a composition A and / or a composition B; the composition A comprises a deodorizing compound, an optional antioxidant, an optional preservative, an optional aroma compound, an optional surfactant and an optional defoaming agent; the deodorizing compound comprises an alcohol compound, unsaturated fatty acid and salt; and the composition B comprises a deodorization inorganic compound and / or a deodorization organic compound, and an optional solvent. According to the properties of stink compounds, the optimal odor compound raw materials and the optimal compatibility combination are selected, and the composition of the invention has the advantages of good deodorization effect, small spraying amount, good durability, quick effect and the like.

Description

technical field [0001] The invention relates to the technical field of harmless treatment and recycling of solid waste, in particular to a composition, preparation and application for removing odors related to ammonia and nitrogen compounds. [0002] noun definition [0003] (1) Odor: Refers to all gaseous substances that stimulate the olfactory organs, cause people's unpleasantness and damage the living environment. (Quoted from "Discharge Standard of Odor Pollutants" GB14554-93). [0004] (2) Nitrogen compound odor: refer to the compound odor substance containing nitrogen (N), and the present invention does not include nitrile compounds (the compound that hydrocarbons are connected with the carbon atom of cyano-C≡N, the general formula is R-C≡N N). [0005] (3) Ammonia: NH 3 , has a strong pungent odor gas, flammable, when NH 3 When the concentration (V / V) reaches 15.7%-27.4%, it can explode. Experimental results, when NH 3 The concentration reaches 680mg / m 3 When NH...
