Description

Technical Field

[0001] The present invention relates to the field of ozone concentration detection, and in particular to an ozone concentration detection device and a detection method. Background Art

[0002] As a strong oxidant, ozone has a strong ability to kill bacteria and disinfect. In the disinfection process, a certain ozone concentration is an important parameter to ensure the disinfection effect. By detecting the ozone concentration after disinfection, it can be ensured that the ozone reaches the dose required to kill bacteria, viruses and other microorganisms, thereby verifying the effectiveness of the disinfection operation. For example, when the ozone concentration is 0.08-0.6ppm, the average killing rate of Escherichia coli in the bacterial propagules in the air for 30 minutes can reach 84.60%-99.9%; and when the ozone concentration is 0.34-0.85ppm, the killing rate can reach 99.47%-99.97% for 10-30 minutes. These data show that the ozone concentration is closely related to the disinfection effect. Although ozone shows a strong bactericidal ability during the disinfection process, excessive ozone concentration will pollute the environment. my country's ambient air quality standards stipulate the concentration limit of ozone to ensure that the air quality will not cause harm to human health. By detecting the ozone concentration after disinfection, ozone emissions can be discovered and controlled in a timely manner to prevent them from exceeding the environmental capacity, causing air pollution and impacts on human health.

[0004] The ozone concentration detection device in the prior art has the following shortcomings: 1.

[0019] Embodiment 1, as Figure 1-Figure 4 As shown, an ozone concentration detection device proposed by the present invention includes a shell 1, an ozone collecting component 2, a concentration detection component 3 and a ventilation adjustment handle 4. The shell 1 is provided with air inlets 101 at the top, bottom, left and right sides, a display screen and buttons are provided at the front end, and an air outlet 102 and a plug are provided at the rear end; the ozone collecting component 2 is located at the front end of the shell 1, and the air inlet parts 201 thereon are connected to the air inlet 101 one by one, and the collecting component 202 is connected to multiple groups of air inlet parts 201, and the air in the multiple groups of air inlet parts 201 is inhaled by the driving component 203 under reduced pressure to filter and collect ozone, and then the ozone is transferred to the air inlet pipe 5 under pressurization by the driving component 203; the concentration detection component 3 is located at the rear end of the shell 1, and the concentration component 301 thereon is connected to the air inlet pipe 5 and connected to the air outlet 102 through the air outlet pipe 6, the concentrator 301 reduces the volume and increases the concentration by pressurizing the ozone; the light source emitting component 302 and the light source detecting component 303 constitute a detection light path penetrating the concentrator 301, and the ozone concentration is detected by the absorption characteristic of ozone to ultraviolet light; the ventilation adjustment handle 4 is arranged on the shell 1, and the ends are rotated from both sides of the shell 1 to connect to the internal space of the shell 1. On the one hand, the air circulation inside the shell 1 is realized through the hollow and the guide setting, and on the other hand, the overall movement and support of the device are realized through the rotation adjustment.

[0020] like Figure 5As shown, the air intake member 201 is radially arranged around the outer periphery of the collecting member 202 ; the driving member 203 is located on one side of the collecting member 202 ; and the air intake pipe 5 is located on the other side of the collecting member 202 .

[0021] The collecting member 202 collects and filters the air introduced by the air inlet member 201, and then transfers it to the air inlet duct 5. In this process, impurities in the air are separated, which reduces the damage to the device caused by impurities, and is conducive to improving the accuracy of ozone detection.

[0022] like Figure 6-Figure 7 As shown, the collecting member 202 includes an outer collecting tube 20201 with a through hole 1 20203 on the side wall; the inner collecting tube 20202 is rotatably arranged in the outer collecting tube 20201, and a through hole 20204 corresponding to the through hole 1 20203 is arranged on the side wall; a gas separation membrane is arranged on the through hole 20204. The air inlet member 201 is connected to the through hole 1 20203 in a one-to-one manner. The driving member 203 is arranged on one side of the outer collecting tube 20201 to adjust the rotation of the inner collecting tube 20202 and the pressure change. The air inlet pipe 5 is arranged on the other side of the outer collecting tube 20201, connected to the inner collecting tube 20202, and valves 1 20205 are arranged at both ends.

[0023] By rotating the inner collecting cylinder 20202, the through hole 1 20203 and the through hole 2 20204 are adjusted to be connected or staggered. When the through hole 1 20203 and the through hole 2 20204 are connected, the air entering the air inlet 201 is separated into ozone by the gas separation membrane, and is collected in the inner collecting cylinder 20202, and finally transferred through the air inlet pipe 5. When the through hole 1 20203 and the through hole 2 20204 are staggered, the gas separation membrane can be protected and its service life can be extended. Of course, the size of the filtering area can also be adjusted by staggering the through hole 1 20203 and the through hole 2 20204 to meet different filtering requirements.

[0024] It should be further explained that the driving member 203 includes a driving box 20302 located on the outer collecting cylinder 20201; the driving tube 20305 rotates and passes through the driving box 20302 and the outer collecting cylinder 20201, one end of which is connected to the inner collecting cylinder 20202, and the other end is connected to the pressure regulator 20301, and a piston plate 20306 is arranged in the driving tube 20305; the piston plate 20306 is driven to move horizontally through the pressure regulator 20301 to adjust the pressure in the inner collecting cylinder 20202; the gear 1 20304 is keyed to the driving tube 20305, and at the same time one side is meshed and connected to the gear 2 20303; the motor 1 is arranged on the driving box 20302, and drives the gear 2 20303 to rotate.

[0025] When adjusting the connection or interlacing of through hole 1 20203 and through hole 2 20204, the motor 1 drives gear 1 20304 and gear 2 20303 to rotate, and the driving tube 20305 can drive the inner collecting tube 20202 to rotate. When adjusting the pressure of the inner collecting tube 20202, the piston plate 1 20306 moves toward the direction close to the inner collecting tube 20202, so as to increase the pressure and accelerate the discharge of the gas in the inner collecting tube 20202. When the air intake pipe 5 is closed, the piston plate 1 20306 moves toward the direction away from the inner collecting tube 20202, so as to reduce the pressure, accelerate the suction of air in the air intake member 201, and promote the air to pass through the gas separation membrane.

[0026] like Figure 8 As shown, the air intake member 201 includes an air intake cylinder 20101 having one end connected to a through hole 20203 and the other end connected to the air intake port 101; a filter sleeve 20102 is detachably arranged on the air intake port of the air intake cylinder 20101, and a filter screen 20103 is arranged inside.

[0027] It should be further explained that the filter sleeve 20102 extends from the air inlet 101 and is threadedly connected to the air inlet cylinder 20101.

[0028] It should be further explained that the filter 20103 is arranged in multiple layers with different filtering levels to intercept particles and impurities in the air.

[0029] By providing a detachable and multi-stage filtering filter sleeve 20102, on the one hand, the air intake cylinder 20101 is protected and blockage is reduced; on the other hand, the intake air is filtered to improve the accuracy of ozone detection.

[0030] like Fig. 9 As shown, the front end of the concentrator 301 is connected to the air inlet pipe 5, and the rear end is connected to the air outlet pipe 6; the light source emitting component 302 and the light source detecting component 303 are respectively located on the left and right sides of the concentrator 301; and a valve 2 is provided on the air outlet pipe 6.

[0031] Gas is composed of a large number of molecules that move freely in space. When external pressure is applied to the gas, the gas molecules are compressed and the average distance between molecules decreases, resulting in a reduction in the volume of the gas. By pressurizing ozone, the gas volume is reduced, the ozone concentration is increased, and the accuracy of the detection is improved.

[0032] like Fig.10As shown, the concentrator 301 includes a concentrator box 30101; a piston plate 30102 that moves up and down is arranged inside the concentrator box 30101; a pressure regulating chamber connected to the pressure regulator 30103 is arranged on the top of the piston plate 30102, and a compression chamber connected to the air inlet pipe 5 and the air outlet pipe 6 is arranged on the bottom; and light-transmitting windows that are opposite to each other are arranged on the side walls of the compression chamber. The light source emitting component 302 includes a light source emitting box 30201; the light source emitting box 30201 covers the light-transmitting window on one side and is provided with a light source emitter 30202; the light source detection component 303 includes a light source detection box 30301; the light source detection box 30301 covers the light-transmitting window on the other side and is provided with a light source detector 30302.

[0033] The air inlet pipe 5 transfers the ozone collected in the inner collecting cylinder 20202 to the concentrator 301. After the piston plate 2 30102 descends to pressurize and concentrate it, the light source emitting element 302 on one side generates ultraviolet light with a stable wavelength of 254nm (or 253.7nm). The light wave filter filters out ultraviolet light of other wavelengths. The ultraviolet light passes through the concentrator 301, and the photoelectric sensor converts the optical signal of the ultraviolet light into an electrical signal. Finally, the data processing system receives the electrical signal output by the photoelectric sensor and calculates the concentration of ozone.

[0034] like Fig.11 As shown, the ventilation adjustment handle 4 includes a ventilation seat 403 that rotates and penetrates the housing 1; the ventilation sleeve 401 is located outside the housing 1, and one end is connected to the ventilation seat 403; the telescopic elbow 404 is slidably connected to the other end of the ventilation sleeve 401; the two ends of the ventilation pipe 405 are respectively connected to the telescopic elbows 404 on both sides. Two sets of ventilation seats 403 are located opposite to each other, and both are equipped with fans 402; one set of fans 402 supplies air, and the other set of fans 402 exhausts air, so that the ventilation adjustment handle 4 and the housing 1 form an air circulation.

[0035] The fan 402 guides the air intake in the housing 1 to the ventilation adjustment handle 4 to increase the internal air circulation and accelerate the cooling. In addition, the ventilation adjustment handle 4 can be carried by hand to facilitate the movement of the device. When the device is working, the ventilation adjustment handle 4 can be rotated to the bottom so that the front end of the device is tilted, which is convenient for exposing the air inlet 101 at the bottom and also convenient for operating the display screen and buttons.

[0036] It should be further explained that sealing pieces 407 are provided at both ends of the ventilation pipe 405, and a cooling pipe 406 is provided inside which penetrates the sealing piece 407 and is connected to the telescopic elbow 404; the ventilation pipe 405 is filled with refrigerant around the cooling pipe 406; the refrigerant can be water, and the air inside the shell 1 is drawn out and passed through the cooling pipe 406, so as to achieve the purpose of cooling it and reduce the influence of temperature on ozone detection.

[0037] Embodiment 2: This embodiment proposes an ozone concentration detection method, using the ozone concentration detection device described in Embodiment 1, and the detection steps are as follows: S1. Turn the ventilation adjustment handle 4 to the bottom, so that the front end of the device is tilted up to expose the air inlet 101 at the bottom; S2. Before the ozone disinfection device works: the inner collecting cylinder 20202 rotates, the through hole 1 20203 is adjusted to be connected with the through hole 20204, and the piston plate 1 20306 moves in the direction away from the inner collecting cylinder 20202, driving the external air to pass through the air inlet 201 and the gas separation membrane to be filtered and collected in the inner collecting cylinder 20202, and the piston plate 1 20306 moves in the direction close to the inner collecting cylinder 20202, driving the air to be transferred from the air inlet pipe 5 to the concentrator 301; the piston plate 2 30102 descends to pressurize and concentrate it, and then starts to detect the ozone-free air; S3, after the ozone disinfection device works: after the gas in the concentrator 301 is emptied, it moves in the direction away from the inner collecting cylinder 20202 through the piston plate 1 20306, driving the external ozone-containing air to pass through the air inlet 201 and the gas separation membrane to be filtered and collected in the inner collecting cylinder 20202, and moves in the direction close to the inner collecting cylinder 20202 through the piston plate 1 20306, driving the ozone-containing air to be transferred from the air inlet pipe 5 to the concentrator 301; after the piston plate 2 30102 descends to pressurize and concentrate it, the ozone-containing air is tested; S4. Compare the test data before and after the ozone disinfection device works, correct and analyze the test results, and obtain the ozone content in the air. After the test is completed, the inner collecting tube 20202 rotates, adjusts the through hole 1 20203 and the through hole 2 20204 to be staggered, and stops ventilation.

[0038] During the above detection process, the ventilation adjustment handle 4 works to guide the air in the housing 1 into the wind circulation through the fan 402, thereby accelerating the air circulation, achieving the purpose of cooling the environment and reducing the influence of temperature on ozone detection.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
