Problems solved by technology

However, the surface of ordinary activated carbon is non-polar, and it essentially relies solely on physical adsorption to remove bad odors. Therefore, there is a disadvantage that it does not have sufficient adsorption performance for gases with low boiling points such as hydrogen sulfide and ammonia.

Embodiment 1

[0066] Structural activated carbon used in the present invention is different from activated carbon used in conventional deodorants. Comparison of odor removal efficiency

[0067] Structural activated carbon (particle diameter: 3mm, specific surface area: 1100m 2 / g, manufactured by Kuraray Corporation) and a conventional deodorant for air purifiers (particle size: 0.1mm, specific surface area: 1100m 2 / g, manufactured by Kuraray Corporation) and compared the odor removal efficiency of activated carbon of the component, the results are shown in Figure 1a and Figure 1b .

[0068] First, put 1 g of the structural activated carbon used in the manufacture of the deodorant of the present invention and 1 g of the activated carbon used in the conventional deodorant into a U-shaped reactor, and pass air through it to achieve a clean state without impurities. state.

[0069] Then, the sample gas whose flow rate and concentration are adjusted is injected into the MFC. The typ...

Embodiment 2

[0079] Manufacture of deodorant (a)

[0080] Drop into 40g copper compound (CuCl2) and 50g manganese compound (MnCl2) in 100ml water, and dissolve under stirring, in this aqueous solution, drop into 1000g and the same particle diameter of embodiment 1 is the structure active carbon of 3mm, and keep 0.5 hour Then take it out, and then dry it at 100°C for 8 hours. At this time, EDX (Energy Dispersive X-ray Spectroscopy) was used for analysis. As a result, when the weight of the structural activated carbon was used as a basis, the adhesion amounts of the copper compound and the manganese compound on the structural activated carbon were 5.5% by weight and 3.5% by weight, respectively. weight%.

[0081] The adhesion process was adjusted so that the adhesion amount of the copper compound and the manganese compound was maintained at the above adhesion amount to produce a deodorant. At this time, the particle size of the structural activated carbon was changed to 1 mm unit.

Embodiment 3

[0091] Evaluation of Deodorizing Performance of Different Deodorants According to Compounds Adhering to Structural Activated Carbon

[0092] Manufacture of deodorants

[0093] Put 100g copper compound (CuCl 2 ) and 100g manganese compound (MnCl 2 ), dissolved under stirring, and in this aqueous solution, drop into 1000g the same particle diameter as Example 1 and be the structural activated carbon of 3mm, and take out after keeping 0.5 hour, then dry at 100 ℃ for 8 hours. At this time, EDX analysis showed that the adhered amounts of the copper compound and the manganese compound on the structured activated carbon were 8.2% by weight and 6.4% by weight, respectively, based on the weight of the structured activated carbon (1).

[0094] Deodorants (2 to 5) were manufactured as shown in Table 3 below by adjusting the type of metal compound to be adhered and / or the particle size of the structured activated carbon. At this time, the zinc (Zn) compound is Zn (NO 3 ) 2 . The...

Abstract

The invention relates to a deodorizing agent for removing mephitis source materials generated from food garbage treatment device, and manufacturing method and use thereof. The deodorizing agent is absorbed on surface of active carbon with 1-5mm average particle size and comprises adhesive of 0.1-10 wt% of copper compound and 0.05-8 wt % of manganese compound by using active carbon weight as standard. The deodorizing agent is especially adapted for absorbing and removing methanethiol, acetaldehyde, ammonia and acetic acid contained in mephitis generated from food garbage treatment device.

Description

technical field [0001] The present invention relates to a deodorant for removing odor source substances generated from food waste disposal equipment, a method for producing the deodorant, and uses thereof. In more detail, the present invention relates to a deodorant that has adhered copper and manganese compounds on the surface of activated carbon with a specific structure and is suitable for removing odor source substances generated from food waste disposal equipment, etc. Method of manufacture and use of odorant. Background technique [0002] With the economic growth of industrialization and the improvement of living standards, people pay more and more attention to the treatment of stench. In particular, in areas with high population density and dense industrial facilities and residential installations, there are very many problems caused by bad odors from various causative substances. Due to the complex action of odor-inducing substances or the differences between indiv...
