For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] To achieve the above purpose, Figure 1-4As shown, the present invention provides a highly efficient and recyclable organic gas detection converter, comprising: an outer shell 1, a fan 3, a photoelectric sensitive sensor 4, an electrostatic dust removal device 5, a photocatalyst catalytic decomposition device 8, a molecular sieve 9 and a sodium carbonate storage box 10; the outer shell 1 is provided with an opening at the top, and the fan 3, the photoelectric sensitive sensor 4, the electrostatic dust removal device 5, the photocatalyst catalytic decomposition device 8, the molecular sieve 9 and the sodium carbonate storage box 10 are sequentially arranged inside the outer shell 1 from top to bottom; a display controller 6 is installed on the outer wall of the outer shell 1, and the display controller 6 is electrically connected to the fan 3, the photoelectric sensitive sensor 4, the electrostatic dust removal device 5, and the photocatalyst catalytic decomposition device 8 respectively. The outer shell 1 is cylindrical. The photoelectric sensitive sensor 4 is used to detect the concentration of organic gas. When the organic gas reaches a certain concentration, the machine starts to operate. When the organic gas concentration is too high, the machine will sound an alarm.

[0025] The present invention has a compact structure and high-efficiency multi-layer adsorption, and can be placed at any position indoors; the photoelectric sensitive sensor 4 is used for data analysis, and the changes in air pressure and indoor organic gas concentration are monitored according to the gas flow rate, and the reaction concentration of indoor organic gas is detected in real time, and the organic gas concentration and the saturation time of the molecular sieve 9 are fed back. The molecular sieve 9 and substances such as sodium carbonate that have reached adsorption saturation are recovered in the device, and organic gases that are harmful to the environment and human body can be concentrated and harmlessly treated, which is environmentally friendly.

[0026] The photoelectric sensitive sensor 4 can sense the concentration in the surrounding air. When the concentration of organic gas reaches the preset concentration, the sensor sends a signal to the machine behind, and the machine starts to operate. The fan 3 is automatically turned on. Under the action of the fan 3, the unpurified indoor air first flows through the corona zone with high voltage electricity (in the case of positive corona discharge), and the air molecules are converted into positive ions and free electrons, and the dust particles are charged in the process. When the charged particles pass through the dust collecting plate of the electrostatic dust removal device 5, they are adsorbed by the dust collecting plate with opposite polarity and deposited on the dust collecting plate. After dust removal and sterilization by the electrostatic dust removal and filtration device, the air enters the photocatalytic decomposition area. The solid photocatalyst material of the bardi undergoes a hydrolysis reaction under the irradiation of the ultraviolet lamp, and decomposes harmful substances such as TVOC in the air into negative oxygen ions, water and carbon dioxide. The purified air is passed into the zeolite molecular sieve MCM-41 material. The molecular sieve filtration system can absorb harmful impurities such as carbon dioxide oxygen anions. After the molecular sieve 9 is adsorbed, the sodium carbonate further absorbs carbon dioxide.

[0027] To further optimize the technical solution, the outer shell 1 is provided with a sodium carbonate liquid inlet 11 and a waste liquid outlet 12, both of which are connected to the sodium carbonate storage box 10, and a valve 13 is installed at the waste liquid outlet 12.

[0028] To further optimize the technical solution, a dustproof net 2 is provided at the opening at the top of the outer shell 1 .

[0029] To further optimize the technical solution, a dust filter device 7 is provided between the electrostatic dust removal device 5 and the photocatalytic decomposition device 8. The dust filter device 7 includes a pre-filter 14, an anti-allergen filter 15, filter cotton 16, a deodorizing filter 17 and a frame 18. The pre-filter 14, the anti-allergen filter 15, the filter cotton 16 and the deodorizing filter 17 are arranged inside the frame 18 from top to bottom, and a sealing ring 19 is coated on the outside of the frame 18. The filter cotton 16 includes a HE-PA high-efficiency filter and a sponge net, and the HE-PA high-efficiency filter and the sponge net are bonded. After the indoor air flows through the electrostatic dust removal device 5, it enters the dust filter device 7, and the HE-PA high-efficiency filter and the sponge net double dust removal of the particulate pollutants in the air, and the PM1.0, PM10 and other particulate matter contained in the air are efficiently removed. At the same time, the particulate matter can be prevented from entering the next stage, and the service life of the photocatalytic decomposition device 8 is extended.

[0030] The photocatalytic decomposition device 8 includes a bagged solid photocatalyst material and an ultraviolet lamp; the ultraviolet lamp is located on one side of the bagged solid photocatalyst material. When air enters the photocatalytic decomposition device 8, the bagged solid photocatalyst material undergoes a hydrolysis reaction under the irradiation of the ultraviolet lamp, decomposing harmful substances such as TVOC in the air into negative oxygen ions, water and carbon dioxide.

[0031] The zeolite molecular sieve MCM-41 used in the present invention is an artificially synthesized ionic porous aluminosilicate, which has a well-arranged orderly pore structure and a large specific surface area, and has a high thermal stability; it has a strong Coulomb field and polarity inside, and can polarize molecules through electrostatic induction, and has a good adsorption effect on formaldehyde molecules with a strong polarizability and a C=O polar group. The purified air is passed into the molecular sieve filtration system, and the molecular sieve 9 can absorb harmful impurities such as carbon dioxide oxygen anions. After the molecular sieve 9 absorbs harmful gases, the treated gas further enters the sodium carbonate absorption zone, and the sodium carbonate solution further absorbs and treats carbon dioxide.

[0032] The present invention provides a highly efficient and recyclable organic gas detection converter, which uses a photoelectric sensitive sensor to determine whether the toxic gas content exceeds the standard through concentration, and then controls the opening and closing of the entire device, as well as a composite molecular sieve mesoporous filtration system, which controls the adsorption capacity and selectivity of the molecular sieve by balancing the pressure point, and achieves a precise screening effect of molecules. At the same time, a sodium carbonate solution is used for tail gas treatment, breaking the disadvantage that the traditional organic gas detection converter must be replaced within a period of time. The device of the present invention is in line with the purpose of promoting the clean and developing circular economy, absorbing and harmlessly treating organic gases that are harmful to the environment, recycling materials such as molecular sieves and photocatalysts, and protecting the ecological environment; efficiently absorbing indoor organic gases that are harmful to the human body, and protecting human health; the device of the present invention meets social needs, and meets the needs of today's families and markets for efficient and environmentally friendly organic gas purification devices. The device of the present invention can improve people's living air quality and enhance happiness.

[0033] 1. The configuration design of electrostatic dust removal device is as follows:

[0034] η=1-exp(-w)

[0035] The above formula is used to derive the dust removal efficiency, which is the Doychi formula, η = 1-exp(-A1 / Q*ω), where: η is the dust removal efficiency per unit time, %; A1 is the cross-sectional area in the airflow direction, m 2 ; Q is the gas flow rate per unit time, m 3 / s;

[0036] The discharge electrode thin wire is connected to a 13kV voltage; the dust collecting electrode metal plate is connected to a 5kV voltage. On the basis of the structure determination, the specific related parameters should be further determined, such as the number of channels, plate spacing, dust collecting electrode length, etc. The specific parameter calculation steps are as follows:

[0037] ① Estimate the gas flow rate Q (unit: m 3 / h)

[0038] The quality of an organic gas detection converter is usually measured by purification efficiency, that is, the volume of air that can be purified per hour. In the design of this embodiment, the purification area is required to be 120m in one hour. 2 , a room with a height of 2.5m, and ensuring the air circulation frequency once per hour, the required air volume is:

[0039] Q = 120 × 2.5 × 1 = 300m 3 / h

[0040] The designed organic gas detection converter uses KT20060H fan, the maximum air volume of which when working alone is 6.88m 3 / min, that is 412m 3 / h, which can ensure that the organic gas detection converter is 300m / h 3 / h of purified air volume meets the design requirements.

[0041] ② Estimate the electric field wind speed v (unit: m / s)

[0042] As for the electric field wind speed v, according to the data obtained from the survey, the electric field wind speed of the electrostatic dust collector is often controlled at 0.5m / s to 2m / s. In this design, the electric field wind speed is taken as 1m / s.

[0043] ③ Driving speed w (unit: m / s)

[0044] In actual operation, the driving speed will be affected by the charge of the particles, the stability of the working voltage of the electrostatic dust collector, etc. Therefore, referring to the industrial electrostatic precipitator and empirical values, the driving speed is taken as 0.1m / s.

[0045] ④ Calculate the cross-sectional area F(m 2 )

[0046]

[0047] Where: F is the cross-sectional area, m 2 ; Q is the gas flow rate, m 3 / h; V is the electric field wind speed, m / s.

[0048] ⑤Electric field strength E(V / cm)

[0049] The electric field strength in the dust collecting area is generally 3-7 kV / cm, and the working strength of the electric field is mainly determined by the plate-plate spacing in the dust collecting area and the working voltage. In the design of this embodiment, the electric field strength is 6.25 kV / cm, and the design requires a voltage of 5 kV.

[0050] Then the distance between the plates in the dust collecting area is:

[0051]

[0052] Where: b is the cross-sectional area of ​​the dust collecting area, the distance between the plates, cm; v1 is the working voltage, kV; E is the electric field strength, kV / cm.

[0053] ⑥Height of dust collecting plate h (unit: m)

[0054]

[0055] Where: F is the cross-sectional area, m 2 .

[0056] ⑦Number of electrostatic dust collection channels n

[0057]

[0058] Where: F is the cross-sectional area, m 2 ; b is the cross-sectional area of ​​the dust collecting area plate-to-plate distance, cm; h is the height of the dust collecting electrode plate, m; In the design of this embodiment, the number of channels is 37.

[0059] ⑧Dust collecting plate length L(m)

[0060]

[0061] Where: A2 is the particle deposition area, m 2 ; Here, the particle deposition area is taken as 1.6m 2 ; n1 is the number of electrostatic dust collection channels; h is the height of the dust collecting plate, m.

[0062] 2. Design of filtering and dust removal device

[0063] ① The width of the area where the filter dust removal device is located (unit: mm)

[0064] In this embodiment, the width of the area where the filter dust removal device is located is consistent with the width of the area where the electrostatic dust collection device is located, so the width of the area where the filter dust removal device is located is:

[0065] y=(δ1+b)×n-δ1=(l+8)×37-1=332mm;

[0066] In the formula: δ1-dust collecting plate thickness, mm; b-cross-sectional area of ​​dust collecting area, distance between plates, mm; n-number of electrostatic dust collecting channels.

[0067] ② Filter cotton (HEPA net and sponge net) placement device height h1 (mm) According to market research, the thickness of the filter cotton is 20mm, so the filter cotton placement device height is

[0068] h1=30mm

[0069] Filter cotton (HEPA net and sponge net) placement device length x (unit: mm)

[0070] The length of the ultraviolet lamp tube in the ultraviolet sterilization area is 320mm. In order to reduce the volume of the organic gas detection converter, the length of the ultraviolet lamp tube is taken as the total width of the organic gas detection converter.

[0071] In order to reduce the volume of the air purifier, the length of the filter cotton placement device is:

[0072] x=320-48-220-2×1-1=49mm.

[0073] 3. Design of bagged solid photocatalyst material

[0074] ① The length of the area where the bagged solid photocatalyst material is located x1 (unit: mm)

[0075] The size of the photocatalyst bag obtained by screening is 50mm×50mm×25mm. According to the size of the purification area, 20 bags of bagged catalysts of the same size are used. Considering the adsorption effect of ultraviolet light, filter cotton and photocatalyst, in order to reduce the volume of the air purifier, the length of the area where the bagged Badi solid photocatalyst material is located is:

[0076] x1=(55+5)×5+30.6=330.6mm

[0077] ②The width of the photocatalyst area y1 (unit: mm) can be calculated based on the size of the machine, the specifications of the bagged photocatalyst, etc.:

[0078] y1=(52.9+5)×4+5=236.6mm

[0079] ③Height of photocatalyst area h2 (unit: mm)

[0080] h2=30mm.

[0081] 4. Ultraviolet lamp design

[0082] ①Ultraviolet disinfection dose

[0083] High-intensity ultraviolet rays can kill bacteria and viruses in a short time. The effect of ultraviolet sterilization is also affected by many factors, such as irradiation dose and distance. The sterilization dose is an important index to measure the sterilization effect of ultraviolet lamps.

[0084] This embodiment is designed to select Philips ultraviolet disinfection lamps to kill bacteria and other microorganisms in indoor air. The test shows that the ultraviolet disinfection dose = ultraviolet lamp power × irradiation time / irradiation amount

[0085] The UV sterilization dosage is:

[0086] K=200×1.04×2=416μw·s / cm 2

[0087] ② Length of UV sterilization zone x2 (unit: mm)

[0088] The length of the ultraviolet lamp tube obtained by screening is 320mm, and the length of the ultraviolet sterilization zone is 311.2mm.

[0089] ③ Width of UV sterilization area y2 (unit: mm)

[0090] In the design of this embodiment, the width of the ultraviolet sterilization area and the electrostatic dust removal area differs by the thickness of two glass plates, so the width of the ultraviolet sterilization area is:

[0091] y2=332-3.4×2=325.2mm

[0092] ④ Ultraviolet sterilization area outlet wind speed μ2 (unit: m / s)

[0093] According to the research, it is found that the outlet wind speed of the organic gas detection converter is generally 10m / s to 15m / s. The outlet wind speed of this embodiment is designed to be 12m / s.

[0094] ⑤Exit area A3 (unit: m 2 )

[0095]

[0096] Where: Q1 is the outlet gas flow rate, m 3 / h; μ2 is the outlet wind speed, m / s.

[0098]

[0099] In the formula: x2 is the length of the ultraviolet sterilization zone, mm; y2 is the width of the ultraviolet sterilization zone, mm.

[0100] ⑥ The inlet wind speed u3 of the ultraviolet sterilization area (unit: m / s) The inlet wind speed of the ultraviolet sterilization area is the outlet wind speed of the filtration and dust removal area, that is:

[0101] u3=2.4m / s

[0102] ⑦Retention time t1 (unit: s)

[0103]

[0104] Where: x2 is the length of the ultraviolet sterilization zone, m; u3 is the inlet wind speed of the ultraviolet sterilization zone, m / s.

[0105] ⑧ In order to extend the time of air sterilization under ultraviolet light and allow the ultraviolet light to have enough time to kill bacteria and other microorganisms in the air, the ultraviolet light sterilization area is set in a multi-channel form to increase the residence time of air in this area.

[0106] t 总 =n3·t1=8×0.13=1.04s

[0107] Where: t 总 is the total residence time in the UV sterilization zone, m; n3 is the number of channels in the UV sterilization zone, n3=8; t1 is the one-way residence time in the UV sterilization zone, s; and h3 is the height of the UV sterilization zone (unit: m);

[0108] h3=n3(δ2+b1)=8×(3.4+30)=267mm;

[0109] Wherein: n3 is the number of channels in the ultraviolet sterilization zone; b1 is the glass partition-board distance, b1=30mm; δ2 is the glass plate thickness, δ2=3.4mm.

[0110] Performance testing and analysis

[0111] (1) Figure 4 The figure shows the degradation effect of the photocatalytic organic gas detection converter on HCHO. Curve 1 in the figure indicates that the organic gas detection converter in the sealed chamber is not started; Curve 2 indicates that the organic gas detection converter in the sealed chamber is started, and the activated carbon adsorption layer and the photocatalytic layer act at the same time; Curve 3 indicates that the activated carbon adsorption layer in the organic gas detection converter is taken out, and only the photocatalytic layer is retained. From the experimental results, it can be seen that the organic gas detection converter has a good removal effect on the pollutant HCHO.

[0112] (2) The usage indicators of the organic gas detection converter are shown in Table 1:

[0113]

[0114] Table 1 (3), organic gas detection converter working data parameters, as shown in Table 2:

[0115]

[0116] Table 2

[0117] The present invention adopts multiple technical indicators and multiple filtering devices, including a titanium dioxide catalytic decomposition zone, a molecular sieve precision filtering device, and an ultraviolet sterilization zone, to effectively transform harmful gases. The photoelectric sensitive sensor uses nano zinc oxide composite materials as raw materials, has strong sensitivity, senses the air composition and content of the surrounding environment, and determines whether the toxic gas content exceeds the standard by concentration, thereby controlling the opening and closing of the entire device. When it is detected that the indoor toxic gas content is seriously exceeded, the photoelectric sensitive sensor is connected to an alarm device to remind the user to stay away, providing basic protection for the user's safety and health; if the device detects that the indoor gas concentration is higher than the normal standard range, the device will automatically turn on and perform air purification. The principle of high-voltage electrostatic field is used to make large particles such as dust deviate into the dust collection box. Secondly, the pore size of the molecular sieve is generally at the nanometer to submicron level, which can selectively adsorb and filter substances. The precise filtration of toxic gases is improved, and at the same time, the molecular sieve plays the role of balancing the pressure point. By balancing the pressure point, the adsorption capacity and selectivity of the molecular sieve are controlled to achieve the precise screening effect of molecules.

[0118] 1. This device uses a photoelectric sensitive sensor to determine whether the toxic gas content exceeds the standard through concentration, and then controls the opening and closing of the entire device. As well as a composite molecular sieve mesoporous filtration system, by balancing the pressure point, controlling the adsorption capacity and selectivity of the molecular sieve, achieving a precise screening effect of molecules, while using a carbon dioxide automatic treatment device and a sodium carbonate solution tail gas treatment device, breaking the disadvantage that the traditional organic gas detection converter must be replaced within a period of time.

[0119] 2. The device uses multiple green and environmentally friendly materials, which greatly reduces the environmental pollution caused by product upgrades. At the same time, as people's health awareness continues to improve and they pay more attention to indoor air problems, the organic gas detection converter market will maintain a sustained growth trend.

[0120] 3. The molecular sieve adsorbent industry market is open and competitive. It will be vigorously promoted and applied in the field of organic gas adsorption in the next few years. The molecular sieve has uniform pore size and strong adsorption, which is in line with the goal of promoting clean and developing a circular economy. It can effectively remove indoor organic gases and protect human health. The use of efficient and recyclable organic gas detection converters can improve the shortcomings of the current market. It can be recycled and environmentally friendly. It can effectively filter indoor organic gases, dust, viruses, bacteria and other air pollutants, keep the indoor environment fresh, and improve indoor air quality. At the same time, it can improve the quality of life, reduce the occurrence of respiratory diseases, and protect physical health.
