Problems solved by technology

The adsorption method includes acid-base liquid washing and activated carbon adsorption. The former needs to consume a large amount of chemicals, while the latter is easy to block, frequent replacement, and high maintenance costs; the combustion method is suitable for organic waste gas with high concentration and high calorific value; the high-energy ion method will produce Ozone causes secondary pollution and is not easy to deal with, and the ions produced have strong oxidizing effect, which is corrosive to equipment and has certain harm to the body; biological methods include biological filtration towers and biological deodorants, and the general cost is relatively low. Low, the former requires debugging time, while the latter requires more complicated culture conditions to have an efficient deodorizing effect
[0005] There are certain defects in the above methods for removing ammonia. Based on this, it is necessary to provide a method for removing ammonia that is effective in removing ammonia and is environmentally friendly and pollution-free.

Embodiment 1

[0030] A preparation method of ammonia plant deodorant, comprising the following steps:

[0031] S1. Add 15kg of plant extracts to 50kg of water, stir thoroughly for 30 minutes and set aside; wherein, the plant extracts include 7.5kg of lemon eucalyptus oil and 7.5kg of Burnet eucalyptus extract;

[0032] S2. Ultrasonic disperse 5 kg of cuprous oxide in 20 kg of absolute ethanol, then add 15 kg of tetrabutyl titanate, and then add 5 kg of ethanol solution with a mass concentration of 80%, centrifuge the product after fully reacting, and wash with alcohol , dried in vacuum at 150°C for 4 hours to obtain a solid powder;

[0033] S3. Grind the solid powder evenly and add it to the solution in S1, then add 5 kg of peraluminate, and stir thoroughly for 4 hours to prepare a plant deodorant. The peraluminate here is the general term for calcium aluminate minerals, which is CaO-Al 2 o 3 Minerals produced by the system include dodecaaluminate heptaaluminate and monocalcium hexaalumi...

Embodiment 2

[0038] A preparation method of ammonia plant deodorant, comprising the following steps:

[0039] S1. Add 20 kg of plant extracts to 55 kg of water, stir thoroughly for 40 minutes and set aside; wherein, the plant extracts include 10 kg of Burnet elm extract and 10 kg of Lagerstroemia crape myrtle extract;

[0040] S2. Ultrasonic disperse 7 kg of cuprous oxide in 25 kg of absolute ethanol, then add 20 kg of metatitanic acid, and then add 5 kg of ethanol solution with a mass concentration of 80%, centrifuge the product after sufficient reaction, wash with alcohol, and Vacuum drying at 160°C for 5 hours to obtain a solid powder;

[0041] S3. Grind the solid powder evenly and add it to the solution in S1, then add 7kg of peraluminate, and stir thoroughly for 5 hours to prepare a plant deodorant. In this embodiment, the peraluminate is monocalcium hexaaluminate.

[0042] Wherein, the preparation method of burnet extract or crape myrtle extract is:

[0043] A1. Grind Burnet or La...

Embodiment 3

Abstract

The invention provides an ammonia gas plant deodorant. Plant extracts are used as raw materials, the extracts are eucalyptus citriodora oil, a sanguisorba officinalis extract, a crape myrtle extract and a rose extract, the extracts can continuously release fresh fragrance and have the effects of killing viruses and insects, preventing radiation and refreshing the mind, and meanwhile the plant extracts are non-toxic, harmless, environmentally friendly and free of pollution. The invention discloses a preparation method of the ammonia gas plant deodorant. Cuprous oxide is dispersed in an alcoholic solution; then a titanium dioxide precursor is added to prepare Cu2O / TiO2 solid powder. The Cu2O / TiO2 solid powder serves as a photocatalyst, ammonia gas is decomposed into non-toxic products through active oxygen generated on the surface of the photocatalyst after the photocatalyst is excited by light, and compared with other methods, the photocatalyst method can effectively reduce ammonia pollution of the indoor environment and has a good killing effect on indoor bacteria and other microorganisms.

Description

technical field [0001] The invention belongs to the technical field of chemical environmental protection, and in particular relates to an ammonia plant deodorant and its preparation method and application. Background technique [0002] With the continuous development of social economy, the bearing pressure of the environment is gradually increasing. Some odors produced by production and life not only cause great pollution to the environment, but also seriously affect people's health. Household garbage and feces contain fat and protein, which will produce a variety of odorous substances during the decomposition process, mainly including ammonia, hydrogen sulfide, methyl sulfide, styrene, etc. In interior decoration, due to the use of a large number of fireproof boards and some amine-containing organic substances, the indoor ammonia and benzene levels exceed the standard, which seriously threatens human health. [0003] Ammonia, a colorless gas with a pungent odor, can saponi...
