Description

Technical Field

[0001] This invention belongs to the field of indoor pollution control technology, and specifically relates to a device and method for the synergistic degradation of indoor VOCs through a series multi-interface approach. Background Technology

[0002] Indoor VOCs are widespread in our living environment, primarily originating from various everyday items and activities. Building and decoration materials are significant sources, such as paints, coatings, adhesives, and engineered wood products (particleboard, MDF, etc.) using aldehyde-containing resins (such as urea-formaldehyde resin), which continuously release formaldehyde. Furniture, especially newly purchased engineered wood furniture, upholstered furniture (sofas, mattresses), and carpets, also releases VOCs through their adhesives and fabric treatments. Household chemicals contribute significantly, including cleaning agents, disinfectants, air fresheners, insecticides, dry cleaning residues from dry-cleaned clothes, personal care products (perfumes, hairspray), and office supplies (markers, printer ink). Furthermore, combustion processes such as cooking fumes, tobacco smoke, burning candles and incense, and incomplete combustion in fireplaces and gas stoves also produce VOCs. Other sources include printers / copiers, new clothes treatments, outdoor vehicle exhaust or industrial fumes, and even the metabolic products of certain molds.

[0003] The harm of VOCs to human health cannot be ignored; the severity depends on the type, concentration, exposure time, and individual sensitivity. Short-term exposure to high concentrations (common after new renovations or the use of large amounts of chemicals) can trigger acute symptoms, mainly manifested as irritation to the eyes, nose, and throat (burning sensation, tearing, itching, pain), respiratory discomfort (coughing, chest tightness, wheezing, worsening of asthma), and neurological and systemic reactions such as headache, dizziness, fatigue, nausea, and skin allergies. More serious are the chronic harms caused by long-term or repeated exposure to low concentrations of VOCs. Some VOCs have clear organ toxicity and may damage the liver, kidneys, and central nervous system. Most worryingly, they pose a carcinogenic risk. For example, benzene (common in gasoline and tobacco smoke) has been identified as a contributing factor to leukemia; formaldehyde (a major release from engineered wood products and adhesives) is a known carcinogen and is associated with an increased risk of nasopharyngeal carcinoma and leukemia.

[0004] With increasing public awareness of indoor air pollutants, various pollutant treatment technologies have emerged. Indoor VOCs treatment technologies are mainly divided into three categories: source control, ventilation dilution, and post-treatment purification. Source control is the most fundamental method, directly reducing the types and levels of indoor pollutants by selecting environmentally friendly building materials (such as low-VOC paints and formaldehyde-free plywood), reducing the use of chemical products (such as avoiding spray air fresheners), and pre-ventilating new furniture to dissipate odors. Ventilation dilution is the most economical and effective measure, increasing air circulation through natural window opening or mechanical ventilation systems to control VOCs concentrations within safe ranges, especially suitable for newly renovated environments. Post-treatment purification technologies serve as a supplement, including: 1) activated carbon adsorption, which uses a porous structure to capture gaseous VOCs, but requires regular replacement to avoid saturation; 2) photocatalytic oxidation (PCO), which decomposes organic matter into harmless substances under ultraviolet catalysis, but may produce ozone as a byproduct; 3) air purifier combination technology, integrating HEPA filters (for particulate matter removal) with activated carbon / PCO modules for synergistic effects. In addition, controlling indoor temperature and humidity (maintaining 30%-50% humidity) can slow down the release rate of pollutants, and while some plants have trace absorption capabilities, their effect is limited. For severe pollution, professional treatments such as high-temperature fumigation to accelerate volatilization or sealing agents to block release are necessary. Only by comprehensively applying source control, continuous ventilation, and targeted purification can indoor air quality be effectively improved.

[0005] There are two main challenges to the technologies and purification processes that limit the efficient removal of indoor pollutants: (1) Long latency period. After home decoration, the density of furniture with high concentration of VOCs such as indoor boards is high, and the release period of benzene and aldehyde pollutants can last for 3-15 years, making it difficult to completely solve the indoor VOCs pollution problem in a short period of time.

[0006] (2) High treatment costs and difficult maintenance. Among the existing indoor VOCs treatment technologies, catalysts and adsorbents have good short-term purification effects, but they need to be frequently replaced or regenerated, which increases the treatment cost. Secondly, due to the long treatment cycle, and considering human inertia, replacement is neglected over time, which exacerbates the risk of long-term low-concentration exposure of indoor VOCs to the human body.

[0007] Chinese invention patent application number CN202310387408.8 discloses a VOCs waste gas treatment system based on catalytic oxidation technology, belonging to the field of waste gas treatment technology. To address the problem of cumbersome valve control during intermittent adsorption operation, which requires shutdown for adsorption plate replacement to avoid saturation adsorption, the patent utilizes a first motor to drive a rotating rod, causing a rack below the first filter box to move backward and a rack below the second filter box to move forward. During the backward movement of the rack, a gear ring meshes with the rack, causing it to rotate counterclockwise. The inner side of the gear ring meshes with a sector gear, driving a rotating plate to rotate counterclockwise around the connecting shaft. Ultimately, the rotating plate is fitted into the sealing groove, blocking the connection between the first and second connecting pipes. Conversely, the rotation of the first drive assembly connects the first and second connecting pipes below the second filter box. This patent enables quick valve control for intermittent operation, facilitating the replacement of the internal first filter plate assembly. This patent can achieve uninterrupted treatment of VOCs waste gas, but the equipment investment is large, and the adsorbent that has been saturated still needs to be regenerated, which poses a risk of secondary pollution.

[0008] Utility model patent application CN201420169792.0 discloses an embedded plasma adsorption-catalytic reactor for VOCs treatment, comprising: a horizontal adsorption-catalytic fixed bed, the top of which is the inlet side, the bottom has a discharge port, and both ends are outlet ports, filled with adsorption catalyst; several parallel plasma reactors, each vertically embedded in the horizontal adsorption-catalytic fixed bed, with a closed bottom end fixed to the bottom wall of the bed and an open top end serving as an inlet; and an inclined inlet device located above the horizontal adsorption-catalytic fixed bed, connected to the inlets of all the plasma reactors. This utility model patent integrates plasma oxidation technology, adsorption technology, and chemical catalysis technology, synergistically improving the degradation efficiency and energy utilization of VOCs, enhancing carbon balance during degradation, effectively controlling the generation of harmful byproducts, and efficiently degrading VOCs into harmless CO2 and H2O. While this patent achieves efficient VOCs degradation, it also suffers from high equipment investment and high operating and maintenance costs.

[0009] Given the above challenges, it is essential to find an economical and practical treatment technology that can achieve long-term and continuous purification of indoor VOCs without affecting normal living conditions. Summary of the Invention

[0010] The purpose of this invention is to overcome the shortcomings of existing indoor VOCs treatment technologies and provide a series-connected multi-interface synergistic degradation device and method for indoor VOCs. This method only requires placing a necked-down pipe made of a high dielectric constant material in the air conditioning ventilation duct. When indoor VOCs molecules pass through the necked-down pipe, the size of the neck of the pipe is controlled by a necking adjustment component to achieve different degrees of acceleration of the duct airflow. The condensate in the ventilation duct is atomized into tiny droplets. The solid-liquid-gas interface formed by oxygen in the air, the tiny droplets, and the high dielectric constant necked-down pipe spontaneously generates •OH and •O. 2- The device, which uses H2O2 to oxidize different types of VOC molecules in the duct, and the necking duct and necking regulating components to accelerate the local wind speed and promote the kinetics of the oxidation reaction, thereby enhancing the oxidative degradation of VOC molecules. Furthermore, the device, which uses several necking ducts and necking regulating components arranged in series to synergistically degrade indoor VOCs, has a simple structure, low investment, and only needs to be installed in the air conditioning ventilation duct. It does not need to be replaced in the middle, has a long service life, and has no maintenance costs, thus minimizing the technical cost and making it possible to promote the technology on a large scale.

[0011] To achieve the above objectives, this application adopts the following technical solution: The principle of this invention is as follows: The constricted duct is made of a high dielectric constant material, primarily acting as a medium for electron transfer. When tiny droplets in the ventilation duct come into contact with the constricted duct, electrons from H2O molecules are transferred to the surface of the ventilation duct. The H2O molecules are transformed into water radical cations, which are unstable. Two water radical cations generate two hydrated hydrogen cations and two hydroxyl radicals, further generating one molecule of H2O2. Electrons transferred from water molecules to the surface of the ventilation duct come into contact with the air inside the constricted duct to form •O. 2- These free radicals can react with H. + It combines to form •OOH, which gains electrons again and reacts with H. + They combine to form H2O2. At this point, the necked channel maintains a balance between the gain and loss of electrons, and the necked channel plays the role of electron transfer. Two molecules of H2O and one molecule of O2 complete a full-process reaction of H2O molecule oxidation and O2 reduction. The free radicals generated during the reaction complete the degradation of indoor pollutants.

[0012] This invention discloses a device and method for the synergistic degradation of indoor VOCs through a series of multi-interface interfaces. It can achieve continuous degradation and purification of indoor VOCs without affecting normal living conditions. The necked pipe is made of a high dielectric constant material, and the size of the middle neck can be adjusted by the necking adjustment component. The increased air velocity in the necked pipe can promote the generation of free radicals and hydrogen peroxide during interfacial interactions (solid-liquid and gas-liquid interfaces), thereby accelerating the degradation of different types of VOCs molecules.

[0013] In a first aspect, the present invention provides a series-connected multi-interface synergistic degradation device for indoor VOCs, the device comprising: a plurality of necked pipes, each of the necked pipes being made of a high dielectric constant material; a plurality of necking adjustment components, one end of each of the necking adjustment components being fixed to a ventilation duct, and the other end of each of the necking adjustment components being fixed to the neck of a corresponding necked pipe; and a wind-driven component, the wind-driven component being used to collect condensate on the ventilation duct, water vapor in the air, and different types of VOCs in the necked pipes to form a solid-liquid-gas interface reaction site.

[0014] In the above technical solutions, the outer diameter of each of the necked pipes is equal to the inner diameter of the ventilation pipe.

[0015] In the above technical solutions, each of the necking adjustment components includes: an adjustment body, one end of which is fixed to the ventilation duct and the other end of which is fixed to the neck of a corresponding necking duct; a controller, which is communicatively connected to the adjustment body; and a sensor, which is communicatively connected to the controller.

[0016] In the above technical solutions, the high dielectric constant material includes one of PVC, latex tubing, and PTFE.

[0017] In the above technical solutions, the wind-driven component includes the air supply structure in the air conditioning equipment.

[0018] Secondly, the present invention provides a method for the synergistic degradation of indoor VOCs through a series of multi-interface interfaces. The method involves setting up a plurality of constricted pipes and a plurality of constriction adjustment components in a ventilation duct, and using a wind-driven component to collect condensate on the ventilation duct, water vapor in the air, and different types of VOCs in the constricted pipes to form a solid-liquid-gas interface reaction site. Each constricted pipe is made of a high dielectric constant material. One end of each constriction adjustment component is fixed to the ventilation duct, and the other end of each constriction adjustment component is fixed to the neck of a corresponding constricted pipe.

[0019] In the above technical solutions, the outer diameter of each of the necked pipes is equal to the inner diameter of the ventilation pipe.

[0020] In the above technical solutions, each of the necking adjustment components includes: an adjustment body, one end of which is fixed to the ventilation duct and the other end of which is fixed to the neck of a corresponding necking duct; a controller, which is communicatively connected to the adjustment body; and a sensor, which is communicatively connected to the controller.

[0021] In the above technical solutions, the high dielectric constant material includes one of PVC, latex tubing, and PTFE.

[0022] In the above technical solutions, the wind-driven component includes the air supply structure in the air conditioning equipment.

[0023] This invention provides a device and method for the synergistic degradation of indoor VOCs through a series of multi-interface interfaces. First, a necked pipe with multiple constrictions in the middle is custom-made using a solid material with a high dielectric constant. The outer diameter of the necked pipe is equal to the inner diameter of the air conditioning ventilation duct, providing a reaction site for the synergistic degradation of indoor VOCs through multi-interface interactions. Then, using condensate from the wall of the air conditioning ventilation duct and tiny droplets in the airflow as liquid phase components, under the driving force of the air conditioning system, air, liquid phase components, and the high dielectric constant solid material form solid-liquid and gas-liquid interfaces within the multi-stage series of necked pipes. During the interface contact process, the solid material acts as a medium for electron transfer. During electron transfer, interfacial interactions generate hydroxyl radicals (•OH) and superoxide radicals (•O). 2- This process, accompanied by the generation of hydrogen peroxide (H2O2), occurs when different types of indoor VOCs molecules enter a multi-stage series of constricted ducts through the air conditioning duct. The interaction between multiple interfaces within the constricted ducts generates •OH and •O... 2- Both H2O2 and air purifiers degrade VOC molecules to varying degrees. As the air conditioner compressor circulates and draws in indoor air, it ultimately achieves long-term purification of indoor VOCs.

[0024] Unlike traditional methods of purifying indoor VOCs using catalysts and adsorbents, this invention prepares a necked-off pipe with a high dielectric constant. The outer diameter of the necked-off pipe is the same as the inner diameter of the air conditioning ventilation duct, and the size of the neck in the middle of the pipe is adjustable. Installed inside the air conditioning ventilation duct, and driven by an air conditioning fan, it carries condensate from the inner wall of the duct, water vapor from the air, and different types of indoor VOCs into the necked-off pipe. The airflow velocity increases sharply as it passes through the neck. The diameter of the neck can be adjusted by a sensor, serving two purposes: First, the high-speed airflow atomizes the condensate in the ventilation duct into micro-nano-scale droplets, increasing the specific surface area of ​​the droplets and the contact area between the liquid and the air and the necked-off pipe. Second, the increased airflow velocity as it passes through the neck promotes the kinetics of the degradation reactions of different types of VOC molecules, thereby enhancing the removal of indoor VOCs. Driven by the air conditioning system, air, liquid components, and high dielectric constant solid materials form solid-liquid and gas-liquid interfaces in multi-stage series-connected constricted ducts. During interfacial contact, the solid material acts as a medium for electron transfer. In this process, interfacial interactions generate hydroxyl radicals (•OH) and superoxide radicals (•O).2- This process, along with the generation of hydrogen peroxide (H2O2), occurs when different types of indoor VOCs enter the constricted duct through the air conditioning supply duct. The interaction of multiple interfaces within the constricted duct generates •OH and •O... 2- Both H2O2 and other substances can degrade VOC molecules to varying degrees. The constricted channel allows for electron transfer, with ample oxygen from the air and micro / nano-scale droplets, eliminating the need for replacement or maintenance and solving the problem of high replacement and maintenance costs associated with traditional catalysts or adsorbents.

[0025] To address the challenge of long latency periods for indoor VOCs, a necked-out duct made of a high dielectric constant material is installed in the air conditioning ventilation duct. Driven by the air conditioning system, it forms a solid-liquid-gas multi-interface reaction site, where •OH and •O are spontaneously generated at the solid-liquid and gas-liquid interfaces. 2- With H2O2, the material loss during electron transfer is negligible, and the prepared necked pipe can be used for a long time without replacement, providing a possibility for the persistent removal of indoor VOCs and effectively solving the problem of long latency and release cycles of indoor VOCs pollutants.

[0026] The beneficial effects of this invention are as follows: (1) The multi-stage series necked pipe structure involved in this invention is simple. The size of the neck of the necked pipe can be adjusted by the necking adjustment component to increase the wind speed to different degrees. The manufacturing cost is low.

[0027] (2) The raw materials for manufacturing the multi-stage series necked pipe involved in this invention are widely available, such as PVC, latex pipe, PTFE, etc., and only need to meet the physical characteristic of high dielectric constant.

[0028] (3) The multi-stage series-connected constricted pipes prepared in this invention are installed in air conditioning ventilation ducts. Oxygen and micro-nano-scale liquid droplets are ubiquitous in the airflow inside the pipes. Therefore, under the action of solid-liquid and gas-liquid interfaces, •OH and •O 2- It will spontaneously generate H2O2, and the loss of solid, liquid and gaseous media involved in the reaction process is negligible, which can achieve long-term purification of indoor VOCs.

[0031] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0032] Example 1 This invention provides a device for the synergistic degradation of indoor VOCs through a series of multi-interface interfaces. Please refer to [link / reference]. Figure 1-3 The device includes several constricted pipes 1, several constriction adjustment components 2, and a wind-driven component (not shown in the figure). Each constricted pipe 1 is made of a high dielectric constant material, such as PVC, latex pipe, or PTFE. The outer diameter of the constricted pipe 1 is equal to the inner diameter of the air conditioning ventilation duct 3, and the constricted pipe 1 and the ventilation duct 3 are fixedly connected by the constriction adjustment components 2, so that the neck 11 of the constricted pipe can automatically adjust its size.

[0033] More specifically, the necking adjustment assembly 2 includes an adjustment body, a controller, and a sensor. The adjustment body is located at the neck 11 of the necked duct to fix the ventilation duct 3 and the necked duct 1. The sensor monitors the wind speed inside the necked duct 1 and transmits the signal to the controller. The controller controls the movement of the adjustment body, causing the size of the neck 11 of the necked duct to change. The inlet section 12 and outlet section 13 of the necked duct move along the inner wall of the ventilation duct 3, thereby adjusting the wind speed at the neck 11 of the necked duct. In addition, the wind-driven assembly collects condensate water on the ventilation duct 3, water vapor in the air, and different types of VOCs in the room into the necked duct 1. When passing through the neck 11 of the necked duct, the wind speed increases sharply. The high-speed airflow atomizes the condensate water in the ventilation duct 3 into micro-nano-scale droplets, increasing the specific surface area of ​​the droplets and the contact area between the droplets and the air and the necked duct, thereby promoting the kinetic process of the degradation reaction of different types of VOCs and achieving the purpose of enhanced VOCs removal.

[0034] Example 2 Using a diaphragm pump as the wind-driven component, the two ends of the silicone tube are connected to the air inlet and outlet of the diaphragm pump, respectively. Several constricted pipes and constriction adjustment components are set inside the silicone tube. Formaldehyde and toluene are selected as representative indoor VOCs pollutants. After the diaphragm pump is turned on, a closed environment for multi-interface synergistic degradation of indoor VOCs is created.

[0035] Targeting formaldehyde and toluene as pollutants, under room temperature (25°C) conditions, a larger neck is achieved in the constricted duct using a necking adjustment component. The degradation rates of formaldehyde and toluene after closed-loop operation under different wind speeds are as follows: Figure 4 As shown; when the neck in the constricted pipe is reduced by the constriction adjustment component, the air velocity inside the constricted pipe increases sharply under the same power of the diaphragm pump. After running in the closed pipe for 50 minutes, the degradation rates of formaldehyde and toluene are as follows: Figure 5 As shown in the figure; through comparison, it can be seen that the size of the neck in the constricted pipe does indeed enhance the degradation of formaldehyde and toluene in the reaction system, proving the feasibility of the series-connected multi-interface synergistic degradation device and method for indoor VOCs in this invention. The corresponding air velocity in the ventilation duct of the diaphragm pump at the same power is shown in the table below: Table 1 Wind Speed ​​Correspondence Table Wind speed (m / s) when the neck is larger 2 4 6 8 Wind speed (m / s) when the neck is relatively small 12.5 25 37.5 50 Example 3 The reaction apparatus in Example 2 was further scaled up to 1m. 3Degradation experiments of formaldehyde and toluene were conducted in an environmental simulation chamber. A necked pipe and a necking adjustment component were installed within the internal circulation duct. First, the neck of the necked pipe was enlarged using the necking adjustment component, and the degradation rates of formaldehyde and toluene pollutants were tested at different wind velocities (2 m / s, 4 m / s, 6 m / s, and 8 m / s). Then, the neck of the necked pipe was reduced using the necking adjustment component, with corresponding wind velocities of 12.5 m / s, 25 m / s, 37.5 m / s, and 50 m / s. The degradation rates of formaldehyde and toluene pollutants were tested under these conditions. Figure 6 As shown in the above experimental results, even with an increased reaction space, the device and method provided by this invention still have a high efficiency in degrading indoor pollutants.

[0036] This invention utilizes a necked-off pipe made from a high dielectric constant material (PVC, latex tubing, PTFE, etc.) to provide a reaction site for the degradation of indoor VOCs. The outer diameter of the prepared necked-off pipe is equal to the inner diameter of the ventilation duct. When installed inside an air conditioning ventilation duct, the liquid droplets inside the pipe repeatedly contact with oxygen in the air, forming solid-liquid and gas-liquid interfaces that spontaneously generate •OH and •O. 2- The device, containing H2O2, oxidizes different types of VOCs molecules in the pipe. A necking adjustment component is used to adjust the size of the central neck, thereby regulating the airflow within the pipe and promoting the kinetics of the oxidation reaction, thus enhancing the oxidative degradation of VOCs molecules. The device for degrading indoor VOCs described in this invention has a simple structure, low manufacturing cost, and requires minimal investment. It eliminates the need for subsequent maintenance and replacement, achieving sustained degradation and purification of indoor VOCs molecules without affecting normal living conditions. This saves on operating and maintenance costs and facilitates widespread application.
