Description

Technical Field

[0001] The invention relates to the field of circular economy and environmental protection, and in particular to a compound deodorizing and sterilizing agent for a garbage incineration plant and a preparation method thereof. Background Art

[0002] In people's daily lives, it is inevitable to generate a large amount of domestic waste. If these wastes are not effectively treated, it will greatly affect people's living environment and even threaten people's health. At present, incineration is one of the main ways to deal with garbage, but in the process of incinerating garbage, in addition to producing a lot of odor, it will also breed some viruses and bacteria.

[0003] Therefore, how to remove the toxic and harmful odors and viruses and bacteria generated during the garbage incineration process has become an urgent problem to be solved. Summary of the invention

[0004] The purpose of the present invention is to provide a compound deodorizing and sterilizing agent for use in a waste incineration plant and a preparation method thereof, so as to overcome and solve the problems in the existing product technology.

[0005] In order to achieve the above purpose, the embodiment of the present invention provides the following technical solutions:

[0006] According to a first aspect of an embodiment of the present invention, a compound deodorizing and disinfecting agent for a waste incineration plant is provided. The raw materials for preparing the compound deodorizing and disinfecting agent include, by weight, 1.5-3 parts of natural cedar alcohol dew, 0.1-0.3 parts of eucalyptus oil, 0.8-2 parts of polyhexamethylene biguanide, 0.3-0.5 parts of alkyl dimethyl benzyl ammonium chloride, 0.3-0.5 parts of bis-decyl dimethyl ammonium chloride, 0.4-0.7 parts of nano-polymer quaternary ammonium salt, 1.5-4.5 parts of propylene glycol, and 0.1-0.3 parts of a solubilizer.

[0007] Furthermore, in parts by weight, the raw materials for preparing the compound deodorant and disinfectant include 2.25 parts of natural cedar alcohol dew, 0.2 parts of eucalyptus oil, 1.4 parts of polyhexamethylene biguanide, 0.4 parts of alkyl dimethyl benzyl ammonium chloride, 0.4 parts of bis-decyl dimethyl ammonium chloride, 0.55 parts of nano-polymer quaternary ammonium salt, 3 parts of propylene glycol, and 0.2 parts of a solubilizer.

[0008] According to a second aspect of an embodiment of the present invention, there is provided a method for preparing a compound deodorant disinfectant, comprising the following steps:

[0009] S1, alkyl dimethyl benzyl ammonium chloride, bis-decyl dimethyl ammonium chloride, and nano-polymerized quaternary ammonium salt are mixed to obtain component A for standby use;

[0010] S2, heating the solubilizer, mixing the heated solubilizer with eucalyptus oil and preheated propylene glycol to obtain a dissolve, and mixing the dissolve with natural cedarwood alcohol dew to obtain component B;

[0011] S3, add component A and polyhexamethylene biguanide into the stirred tank, cool down and set aside;

[0012] S4, adding component B into a stirring tank, and allowing the mixture to stand after the reaction is completed to obtain the composite deodorant and sterilizer.

[0013] Furthermore, in step S2, the solubilizing agent is heated to 60°C, and the temperature of the preheated propylene glycol is 60°C.

[0014] Furthermore, in step S2, the mixing mass ratio of the heated solubilizer, eucalyptus oil and preheated propylene glycol is 3:1:1.

[0015] Furthermore, in step S3, the stirring tank is pretreated before adding component A and polyhexamethylene biguanide, and the pretreatment includes cleaning the stirring tank, then adding purified water to 90% of the volume, and heating to 45°C.

[0016] Furthermore, in step S3, the rotation speed of the stirring tank is 60-80 r / min.

[0017] Furthermore, in step S3, the temperature after cooling is 32°C.

[0018] Furthermore, in step S4, the rotation speed of the stirring tank is 60-80 r / min.

[0019] Furthermore, step S4 includes adding component B into a stirring kettle with a rotation speed of 60-80 r / min, running for 30 minutes, sampling and observing the transparency, uniformity and foam level when reaching the preset standard, increasing the speed to 6000 r / min, running for 8 minutes, filtering and standing for 8 hours to obtain a compound deodorant and sterilizer.

[0020] Compared with the existing product technology, the advantages of the present invention are:

[0021] 1. All materials used to prepare the compound deodorant and disinfectant of the present invention are positively charged, and dust in the air becomes negatively charged under the action of the magnetic field, and viruses and bacteria drift on the dust; therefore, the compound deodorant and disinfectant of the present invention can actively adsorb viruses and bacteria when atomizing and disinfecting the air;

[0022] 2. The compound deodorant and disinfectant of the present invention forms a thin film on the surface of the object sprayed by atomization. The film is several dozen times larger than the volume of viruses and bacteria, and tightly wraps the adsorbed viruses and bacteria to inactivate them;

[0023] 3. The composite deodorant and disinfectant of the present invention has the ability to penetrate the envelope of viruses and bacteria, disrupt DNA or RNA, and block autonomous reproduction and transmission. Figure 2-4 As shown, the chemical structure of natural cedar alcohol dew is unique, and some functional groups in the molecules of natural cedar alcohol dew can interact with the cell membrane of pathogens and destroy its structure, thereby achieving the purpose of killing pathogens. At the same time, its oxidizing property can also destroy the cell wall (membrane) of bacteria and inhibit the growth and reproduction of bacteria. The cationic groups in the polyhexamethyl biguanide molecules can have a strong electrostatic effect with the cell wall of pathogenic microorganisms in the negatively charged dust, destroying the integrity of the cells, resulting in the leakage of viral bacterial nucleic acid contents and the death of microorganisms, thereby achieving the killing of pathogenic microorganisms. It can be seen that the present invention destroys the cell wall through polyhexamethyl biguanide, and then destroys the cell membrane through natural cedar alcohol dew, which can play a synergistic role and achieve a fast and efficient sterilization effect, and then eucalyptus oil, alkyl dimethyl benzyl ammonium chloride, dimethyl ammonium chloride, nano-polymerized quaternary ammonium salt, propylene glycol and Tween 60 are used to prepare the deodorant and sterilizing agent of the present invention, achieving a high level of deodorization and sterilization effect;

[0024] 4. After deodorization and sterilization in a waste incineration plant, the compound deodorizing and sterilizing agent of the present invention promotes the conversion and regeneration of resources such as waste incineration power generation and brick making, thus achieving the effect of a circular economy;

[0025] 5. The organic combination of natural cedar alcohol dew with high molecular weight polymer polyhexamethylene biguanide, nano-polymer quaternary ammonium salt components, etc. in the present invention realizes a special structural group with physical and chemical addition, and a series of reactions such as polymerization, decomposition, replacement, and addition occur to toxic and harmful substances in domestic garbage such as methyl mercaptan, hydrogen sulfide, ammonia, and organic amines, thereby prompting odor molecules to change their original molecular structure and decompose quickly, thereby achieving the purpose of purifying soil, water sources, and air.

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The invention provides a compound deodorizing and sterilizing agent for a garbage incineration plant.

[0060] In this step, the natural cedar alcohol solution involves at least one of the following chemical formulas,

[0061]

[0062] A catalyst is usually added to formula (1) to promote the reaction, for example, any one of an acid catalyst, a metal catalyst and a biocatalyst is added, wherein the acid catalyst includes sulfuric acid, the metal catalyst includes Pd, and the biocatalyst includes alcohol dehydrogenase.

[0063]

[0064] Sulfuric acid or phosphoric acid is usually added to formula (2) to promote the reaction.

[0065]

[0066] Usually, sulfuric acid or phosphoric acid can also be added as a catalyst in formula (3).

[0067]

[0068] In formula (4), H+ comes from an acidic catalyst, such as sulfuric acid.

[0069]

[0070] In formula (5), KOH serves as a basic catalyst.

[0071] S3, pre-treating the stirred tank, adding component A and polyhexamethylene biguanide to the pre-treated stirred tank, cooling to 32°C and setting aside; the pre-treatment comprises cleaning the stirred tank, then adding purified water to 90% of the amount, and heating to 45°C; the rotating speed of the stirred tank is 60-80r / min, and the component A is stirred for 15min, and the mixture of component A and polyhexamethylene biguanide is stirred for 15min;

[0073] It can be seen that the present invention destroys the cell wall by polyhexamethyl biguanide, and then destroys the cell membrane by natural cedar alcohol dew, plays a synergistic effect, plays the role of taking advantage of the advantages and avoiding the disadvantages, and achieves the disinfection and sterilization effect, and then is supplemented with eucalyptus oil, alkyl dimethyl benzyl ammonium chloride, dimethyl ammonium chloride, nano-polymerized quaternary ammonium salt, propylene glycol and solubilizing agent to prepare the deodorant sterilizer of the present invention, and realizes efficient deodorization and sterilization instantly. The natural cedar alcohol dew of the present invention has functional groups such as alcohol hydroxyl group and phenolic hydroxyl group in its molecular structure, so that it has excellent adsorption capacity and oxidizability. These functional groups can react chemically with harmful substances in the air, such as organic pollutants such as formaldehyde and benzene, and convert them into harmless substances, thereby effectively purifying the air.
