Description

Technical Field

[0001] This invention belongs to the field of indoor air pollutant treatment technology, and particularly relates to an indoor air pollution treatment method that combines slow-release condensate with a composite spray. Background Technology

[0002] Interior decoration materials continuously release volatile harmful pollutants such as formaldehyde, benzene compounds, ammonia, and TVOCs. Long-term exceedances of these pollutants can seriously endanger the human respiratory system and overall health. Current mainstream remediation methods mainly fall into two categories: direct spraying of chemical agents and photocatalytic decomposition using nano-titanium dioxide. However, both of these existing technologies have the following significant drawbacks:

[0003] First, ordinary chemical spraying agents have a single function, only able to treat free pollutants in the air, and cannot penetrate the gaps in boards and the shallow layers of decorative materials. Deep pollutants continue to leach out, resulting in high residues after treatment and a high risk of rebound. Second, nano-titanium dioxide photocatalysts rely on strong ultraviolet light to activate their catalytic activity. Ordinary indoor environments cannot meet the activation conditions, making them prone to deactivation and unstable purification efficiency in actual use. At the same time, nanoparticles are easy to detach and suspend, posing a carcinogenic risk and causing secondary pollution when inhaled. Third, conventional spraying products, after being sprayed over a large area, easily leave chemical residues on the surfaces of walls and furniture, corroding furniture finishes, damaging the appearance of decorations, and affecting the aesthetics of the interior. Fourth, adsorption products such as activated carbon have low adsorption capacity, are easily saturated, have long treatment cycles, and are slow to take effect, failing to achieve thorough treatment to meet standards.

[0004] It is evident that existing single-method treatments cannot achieve three-dimensional, deep, and long-lasting purification. Therefore, there is an urgent need to develop an indoor air pollution treatment method that integrates multiple products used in sequence, deep purification, film formation and sealing, rapid degradation, no secondary pollution, no damage to furniture, and long-lasting effects without rebound. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides an indoor air pollution control method that combines slow-release condensate with composite spray. It has the advantages of layered and step-by-step synergistic treatment, deep cleaning without rebound, safety without secondary pollution, no damage to furniture appearance, and stable operation without strong light conditions. It solves the problems of weak purification efficiency, easy residue and rebound, reliance on ultraviolet light, easy generation of secondary pollution, and spray marks that damage the decoration surface in the prior art.

[0006] This invention is implemented as follows: a method for treating indoor air pollution using a combination of slow-release condensate and composite spray, comprising the following steps:

[0007] S1. Preliminary preparation: Close all doors and windows, remove obstructions and debris, and evenly place air-purifying slow-release condensate at multiple points in various rooms and inside cabinets;

[0008] S2. First cycle of closed and static: After the air purification slow-release condensate is installed in a closed indoor environment, it is left to stand for 7 days. After the period is over, open the doors and windows to carry out the first full ventilation of the whole house.

[0009] S3. High-polymer spray coating: After the first ventilation is completed, use a frequency conversion spray device to spray the indoor walls, building materials and furniture with high-polymer formaldehyde remover, and let it air dry to form a film.

[0010] S4. Second cycle of closed and static: After the spraying is completed, close the doors and windows again, and install the air purification slow-release condensate in the same way. Continue to close and static for 7 days. After the period, open the doors and windows and carry out the second full ventilation of the whole house.

[0011] S5. Negative ion spraying: After the second ventilation is completed, use a variable frequency spraying device of the same specifications to spray negative ion rapid formaldehyde removal agent into the entire indoor area to complete the integrated treatment of indoor formaldehyde, benzene series, ammonia and TVOC throughout the entire cycle.

[0012] As a preferred embodiment of the present invention, the air-purifying slow-release condensate adopts APF multi-effect purification technology, which integrates four major mechanisms of action: catalytic decomposition, gas penetration, dynamic balance, and controlled slow release. The APF multi-effect purification technology actively releases purification factors, which combine with formaldehyde, benzene, toluene, xylene, ammonia, and TVOC in the air, destroying the physicochemical structure of harmful substances and decomposing them into harmless water, carbon dioxide, and acid radical ions.

[0013] This setup can actively capture and chemically decompose various indoor gaseous pollutants, transforming harmful substances into harmless ones at the source, thus achieving basic purification and degradation.

[0014] As a preferred embodiment of the present invention, the purification factors of the air-purifying slow-release condensate penetrate into the shallow layers of fabrics and decorative materials, gaps in boards and narrow, hidden spaces in a gaseous form. Utilizing the principle of dynamic concentration balance, it forces potential pollutants in building materials to precipitate outwards. The precipitated pollutants are continuously decomposed by the purification factors, preventing a rebound in concentration in the later stages.

[0015] This setup overcomes the limitations of ordinary agents that can only purify the surface, allowing it to penetrate deep into crevices and shallow layers of building materials to uncover hidden pollutants. It also relies on the principle of concentration balance to accelerate the release of internal pollutants, thoroughly eliminating residues and preventing rebounds and exceeding standards after treatment.

[0016] As a preferred embodiment of the present invention, the variable frequency spraying device uses an aluminum spray can with a working air pressure of 0.5-0.9 MPa, a nozzle orifice diameter of less than 1.5 mm, and an atomization spraying distance of less than 1 m.

[0017] This setting ensures that the atomized particles of the agent are fine and the spray is uniform, avoiding drips, lumps, and streaks during spraying. It ensures that the agent adheres evenly to form a film without corroding or contaminating furniture and wall finishes.

[0018] As a preferred embodiment of the present invention, the polymer formaldehyde remover uses polyacrylamide as the core active ingredient. It utilizes the polymer multi-chain structure to combine and solidify with formaldehyde, benzene compounds, and TVOC to form a dense protective film on the surface of the object, thereby blocking and capturing pollutants that continue to be released.

[0019] This setup creates a sealed protective film on the surface of building materials and furniture, physically blocking and adsorbing pollutants that slowly leach out, forming a long-lasting barrier layer and enhancing the stability of the treatment.

[0020] As a preferred embodiment of the present invention, the negative ion rapid formaldehyde remover uses plant-extracted negative ion active ingredients as its core. Through the complexation and neutralization reaction between plant complex ions and positively charged harmful substances in the air, it rapidly degrades pollutants and removes decoration odors.

[0021] This setup utilizes the natural active ingredients of plants to achieve rapid complexation and degradation, quickly dissipating indoor decoration odors and further degrading trace pollutants, thus improving the air quality upon occupancy.

[0022] As a preferred embodiment of the present invention, the air-purifying slow-release condensate operates in two independent 7-day closed cycles. The two ventilation cycles correspond to the end of the first and second cycles, respectively, and ventilation continues until the indoor air is completely circulated and dissipated. The total treatment cycle is 14 days. The air-purifying slow-release condensate uses controlled-release technology to regulate the uniform and long-term release of effective ingredients, which is not limited by the intensity of indoor natural light or ultraviolet light, and continues to exert its purification effect under normal temperature and conditions. The slow-release condensate and the two types of sprays used in the treatment have been verified by animal experiments to be practically non-toxic. There are no drug residues, no corrosion marks on furniture surfaces, and no secondary pollution caused by the inhalation of nanoparticles during the treatment process.

[0023] This setup standardizes the 14-day cycle treatment process, which is standardized, easy to replicate and implement. The slow-release condensate does not rely on ultraviolet light excitation, is suitable for various ordinary indoor environments, and the entire set of agents is safe and non-toxic, with no risk of nanoparticle dispersion, thus avoiding secondary pollution at the source and without damaging the appearance of the decoration.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] This invention employs a sequential process combining slow-release condensate for long-cycle gaseous deep purification, polymer spray for surface film sealing, and negative ion spray for rapid complexation and deodorization. This process constructs a three-dimensional, layered treatment system that achieves excellent treatment results, is non-destructive, highly safe, and produces no secondary pollution.

[0026] Non-damaging: Gas technology requires no spraying, is simple to operate, produces no secondary pollution, and leaves no gaseous residue (air purification condensate).

[0027] Good treatment effect: The purpose of multi-method joint treatment is to make full use of the advantages of different treatment methods to treat indoor pollution in a comprehensive and three-dimensional way, to decompose harmful substances to the greatest extent possible, improve indoor odor, and make the occupancy index reach the permissible concentration range of formaldehyde, benzene, ammonia, toluene, xylene and TVOC specified in GB / T18883-2022.

[0028] High safety and no secondary pollution: Animal experiments were conducted on the products used, and they were identified as practically non-toxic products. The entire set of reagents is practically non-toxic and does not disperse nanoparticles, thus eliminating secondary pollution. Detailed Implementation

[0029] To further understand the invention's content, features, and effects, the following embodiments are provided and described in detail below.

[0030] The present invention will now be described in detail.

[0031] This invention provides a method for treating indoor air pollution using a combination of slow-release condensate and a composite spray, comprising the following steps:

[0032] S1. Preliminary preparation: Close all doors and windows, remove obstructions and debris, and evenly place air-purifying slow-release condensate at multiple points in various rooms and inside cabinets;

[0033] S2. First cycle of closed and static: After the air purification slow-release condensate is installed in a closed room, it is left to stand for 7 days. After the period is over, open the doors and windows to carry out the first full ventilation of the whole house.

[0034] S3. High-polymer spray coating: After the first ventilation is completed, use a frequency conversion spray device to spray high-polymer formaldehyde remover onto the indoor walls, building materials and furniture, and let it air dry to form a film.

[0035] S4. Second cycle of closed and static: After the spraying is completed, close the doors and windows again, and install the air purification slow-release condensate in the same way. Continue to close and static for 7 days. After the period, open the doors and windows and carry out the second full ventilation of the whole house.

[0036] S5. Negative ion spraying: After the second ventilation is completed, use a variable frequency spraying device of the same specifications to spray negative ion rapid formaldehyde removal agent into the entire indoor area to complete the integrated treatment of indoor formaldehyde, benzene series, ammonia and TVOC throughout the entire cycle.

[0037] Specifically, the air-purifying slow-release condensate uses APF multi-effect purification technology, which integrates four major mechanisms of action: catalytic decomposition, gas penetration, dynamic balance, and controlled slow release. The APF multi-effect purification technology actively releases purification factors, which combine with formaldehyde, benzene, toluene, xylene, ammonia, and TVOC in the air, destroying the physicochemical structure of harmful substances and decomposing them into harmless water, carbon dioxide, and acid radical ions.

[0038] The above-mentioned solution can actively capture and chemically decompose various indoor gaseous pollutants, transforming harmful substances into harmless substances at the source and achieving basic purification and degradation.

[0039] Specifically, the purification factors of the air-purifying slow-release condensate penetrate into the shallow layers of fabrics and decorative materials, gaps in boards, and narrow, hidden spaces in a gaseous form. Utilizing the principle of dynamic concentration balance, it forces potential pollutants in building materials to precipitate outwards. The precipitated pollutants are continuously decomposed by the purification factors, preventing a rebound in concentration later.

[0040] By adopting the above solution, we can overcome the limitations of ordinary agents that can only purify the surface, penetrate deep into the gaps and shallow layers of building materials to dig out hidden pollutants, and rely on the principle of concentration balance to accelerate the release of internal pollutants, thoroughly remove residues, and avoid rebound exceeding standards after treatment.

[0041] Specifically, the variable frequency spraying device uses an aluminum spray can with a working air pressure of 0.5-0.9 MPa, a nozzle orifice diameter of less than 1.5 mm, and an atomization spraying distance of less than 1 m.

[0042] By adopting the above solution, it is possible to ensure that the atomized particles of the agent are fine and the spraying is uniform, avoiding drips, lumps, and streaks in the spraying. This ensures that the agent adheres evenly to form a film without corroding or polluting furniture and wall finishes.

[0043] Specifically, the polymer formaldehyde remover uses polyacrylamide as its core active ingredient. It utilizes the multi-chain structure of the polymer to combine and solidify with formaldehyde, benzene compounds, and TVOCs, forming a dense protective film on the surface of the object to block and capture pollutants that continue to be released.

[0044] By adopting the above solution, a sealed protective film can be formed on the surface of building materials and furniture, which can physically block and adsorb and solidify pollutants that slowly precipitate from the inside, forming a long-lasting barrier layer and enhancing the stability of the treatment.

[0045] Specifically, the negative ion rapid formaldehyde remover uses plant-extracted negative ion active ingredients as its core. Through the complexation and neutralization reaction between plant complex ions and positively charged harmful substances in the air, it rapidly degrades pollutants and removes decoration odors.

[0046] The above solution utilizes the natural active ingredients of plants to achieve rapid complexation and degradation, which can quickly dissipate indoor decoration odors, further degrade residual trace pollutants, and improve the air quality when moving in.

[0047] Specifically, the air-purifying slow-release condensate operates in two independent 7-day closed cycles. The two ventilation cycles correspond to the end of the first and second cycles, respectively. Ventilation continues until the indoor air is completely circulated and dissipated, with a total treatment cycle of 14 days. The air-purifying slow-release condensate uses controlled-release technology to regulate the uniform and long-term release of effective ingredients, which is not limited by the intensity of indoor natural light or ultraviolet light and continues to exert its purification effect under normal temperature and conditions. The slow-release condensate and the two types of sprays used in the treatment have been verified by animal experiments to be practically non-toxic. There are no drug residues, no corrosion marks on furniture surfaces, and no secondary pollution caused by the inhalation of nanoparticles during the treatment process.

[0048] The above-mentioned solution adopts a standardized 14-day cycle treatment process, which is standardized, easy to replicate and implement, and the slow-release condensate does not rely on ultraviolet light excitation. It is suitable for various ordinary indoor environments, and the entire set of agents is safe and non-toxic, with no risk of nanoparticle dispersion. It avoids secondary pollution from the source and does not damage the appearance of the decoration.

[0049] This invention employs a sequential combined process of slow-release condensation for long-cycle gaseous deep purification, polymer spray for surface film sealing, and negative ion spray for rapid complexation and deodorization. This constructs a three-dimensional, layered treatment system. Compared to traditional single-spray, photocatalytic, and activated carbon adsorption methods, this invention can penetrate deep into the gaps of boards and the shallow layers of decorative materials to remove hidden pollutants. It relies on dynamic equilibrium to force the pollutant sources to fully decompose and be excreted, resulting in thorough, long-lasting, and non-rebounding treatment. The entire set of agents is practically non-toxic and produces no nanoparticles, eliminating secondary pollution. The atomized spraying is uniform and leaves no streaks, does not corrode furniture or walls, and protects the original appearance of the decoration. The standardized 14-day phased construction process is clear and easy to replicate in large-scale industry applications. After treatment, the indoor air quality meets residential requirements, demonstrating significant advantages in safety and treatment effectiveness.
