Example 1
The present embodiment provides an air treatment device, as shown in fig. 1, comprising at least two wavelength band uv lamps, respectively one or more short wavelength uv lamps 11, one or more vacuum uv lamps 12; further comprises a photocatalyst structural body 2 and a control circuit 3; the control circuit 3 is used for respectively turning on at least part of the ultraviolet lamps in the two wave bands according to the air detection result.
In this embodiment, the short-wave ultraviolet lamp 11 can emit short-wave ultraviolet rays, which can be called UVC or C-band ultraviolet rays, with a wavelength of 200-280 nm; the vacuum ultraviolet lamp 12 may emit vacuum ultraviolet light, which may also be referred to as UVD or D band ultraviolet light, at a wavelength of 100-200 nanometers. In this embodiment, a vacuum ultraviolet lamp with a main line wavelength of 185 nm and a short-wave ultraviolet lamp with a main line wavelength of 254 nm (or 253.7 nm) may be used.
In this embodiment, the irradiation of the photocatalyst structure by the vacuum ultraviolet lamp 12 will generate a large amount of ozone and a small portion of free electrons, while the irradiation of the photocatalyst structure by the short-wave ultraviolet lamp 11 will generate a large amount of free electrons and a small portion of ozone; ozone has strong oxidizability and strong electron-obtaining capability, so that ozone can be rapidly combined with most of generated free electrons to generate Oxygen and air negative ions O (active Oxygen) which are important components in Reactive Oxygen Species (ROS) - The chemical reaction formula is shown as the following formula (1):
e - +O 3 ＝O - +O 2 (1)
the surplus free electrons can be combined with water and oxygen in the air to generate hydrogen peroxide (H) 2 O 2 ) And a superoxide anion (O) 2 - ) And other types of ROS.
In this embodiment, the short-wave ultraviolet lamp 11 and the vacuum ultraviolet lamp 12 are mutually matched, and are turned on together, and products obtained after irradiating the photocatalyst structural body 2 are mutually combined, so that a large amount of non-ozone ROS can be generated, and an effect of effectively purifying air is achieved; the additional product oxygen may further combine with the excess free electrons to produce more non-ozone type ROS, or diffuse directly into the air to increase the ambient oxygen content. In the embodiment, the ozone is used as a resource for generating the non-ozone ROS, rather than being used as a substance for purifying air, and the ozone is consumed by generating the non-ozone ROS, so that the concentration of the ozone can be inhibited, and the harm to a human body caused by the ozone with higher concentration is avoided.
In this embodiment, the photocatalyst structure 2 may be a structure formed of the photocatalyst material itself, or may be a structure coated or supported with the photocatalyst material. The photocatalytic material may include one or more of: titanium dioxide (TiO) 2 ) Zinc oxide (ZnO), tin oxide (SnO) 2 ) Zirconium dioxide (ZrO) 2 ) Cadmium sulfide (CdS), tungsten trioxide (WO) 3 ) (ii) a Other oxide or sulfide semiconductor materials may also be included.
In this embodiment, the position relationship between the photocatalyst structural body 2 and the ultraviolet lamps can be set according to the shape of the light touch structural body, the space shape of the inner cavity of the device, and the like, so as to ensure that ultraviolet rays emitted by each ultraviolet lamp can irradiate at least part of the photocatalyst structural body 2; for example, a photocatalyst screen may surround the UV lamp; then, for example, the ultraviolet lamps can be arranged in a centralized way, and then one or more photocatalyst plates are respectively arranged on different directions; and for example, the ultraviolet lamp is arranged on one or more photocatalyst bearing frames. Wherein the short-wave ultraviolet lamps 11 and the vacuum ultraviolet lamps 12 can be respectively arranged or staggered.
In an implementation manner of this embodiment, the short-wave ultraviolet lamp, the vacuum ultraviolet lamp, and the photocatalyst structure are located as follows:
the short-wave ultraviolet lamp 11 is disposed between the vacuum ultraviolet lamp 12 and the photocatalyst structural body 2.
In this implementation, the short-wave ultraviolet lamp 11 is closer to the photocatalyst structural body 2 than the vacuum ultraviolet lamp 12, and irradiates the photocatalyst structural body 2 earlier than the vacuum ultraviolet lamp 12, so that a product (mainly free electrons) obtained by irradiating the photocatalyst structural body 2 with the short-wave ultraviolet lamp 11 is diffused in an area between the photocatalyst structural body 2 and the short-wave ultraviolet lamp 11, when the photocatalyst structural body 2 is irradiated with the vacuum ultraviolet lamp 12, a large number of free electrons exist in a nearby area, so that the product (mainly ozone) obtained by irradiating with the vacuum ultraviolet lamp 12 can be quickly and fully reacted with the existing free electrons, thereby reducing the possibility that ozone is diffused into the air, and preventing the ozone from exceeding the standard to a certain extent.
An example of this implementation is shown in fig. 2, in which the photocatalyst structural body 2 includes two photocatalyst plates 21 made of photocatalyst material, and the two photocatalyst plates 21 are disposed in parallel and perpendicular to the wind direction (as shown by the arrow in fig. 2).
In the area between the two photocatalyst plates 21, an array of vacuum ultraviolet lamps 12 is placed at the center, and an array of short-wave ultraviolet lamps 11 are respectively placed in the two areas near the photocatalyst plates 21, i.e., the short-wave ultraviolet lamps 11 are located between the vacuum ultraviolet lamps 12 and the photocatalyst plates 2.
This example shows an alternative to placing the short wavelength uv lamp 11 between the vacuum uv lamp 12 and the photocatalyst structure 2, other arrangements are possible that employ the short wavelength uv lamp 11 to separate the vacuum uv lamp 12 from the photocatalyst structure 2.
In this embodiment, the control circuit 3 may include a processing module and a peripheral circuit thereof, and the processing module may be an MCU (Micro Controller Unit), an FPGA (Field Programmable Gate Array), or the like; the control circuit 3 may be implemented by hardware executing software, or may be implemented by pure hardware. The control circuit 3 can directly turn on or turn off the ultraviolet lamp, and can also turn on or turn off the ultraviolet lamp by controlling another driving power supply; a driving power supply can be used for driving one or more ultraviolet lamps in the same wave band or different wave bands.
As an example of this embodiment, as shown in fig. 3, the air processing apparatus includes:
a plurality of vacuum ultraviolet lamps (simply referred to as 185 nm ultraviolet lamps) 121 with a main spectral line wavelength of 185 nm and a plurality of short-wave ultraviolet lamps (simply referred to as 254 nm ultraviolet lamps) 111 with a main spectral line wavelength of 254 nm, wherein the ultraviolet lamps of different bands are respectively arranged in a line and distributed between the two photocatalyst plates 21;
a plurality of driving power supplies 4, wherein each driving power supply 4 is connected with at least one 185 nanometer ultraviolet lamp 111 and at least one 254 nanometer ultraviolet lamp 121;
a control circuit 3 for turning on and off the ultraviolet lamp connected to the driving power source 4 by controlling the turning on and off of the driving power source 4; wherein, when the ultraviolet lamp is turned on, the ultraviolet lamps of 254 nm and 185 nm are turned on together.
In this embodiment, the air detection result may be from one or more detectors, and the detectors may be an integral part of the air treatment device or a separate device outside the air treatment device; the detector sends the air detection result to the control circuit 3 in a wired or wireless mode, or stores the air detection result for the control circuit 3 to read.
The detector can be a microorganism detector, or a detector of one or more types of harmful gases and the like; accordingly, the air detection result may be a microorganism concentration, or a concentration of a harmful gas, or the like. The air treatment herein may include one or more of the following functions: sterilization, disinfection, odor removal, pollutant purification and the like; the corresponding detector/air detection result can be selected for use according to the processing function selected by the user or the current processing mode, for example, when the odor removal or pollutant purification function is started, the harmful gas detector/harmful gas concentration is selected to trigger the ultraviolet lamp to be started, and when the sterilization or disinfection function is started, the microorganism detector/microorganism concentration is selected to trigger the ultraviolet lamp to be started.
The detector can be kept in a normally open state, periodically detects and sends the air detection result to the control circuit 3, and can also detect only when the user opens the corresponding air treatment function or when the control circuit 3 indicates. The detector may actively send the air detection result to the control circuit 3, or may send it to the control circuit 3 only when the control circuit 3 requests the air detection result.
In one implementation of this embodiment, the ratio of the power of the short wave ultraviolet lamp 11 turned on to the power of the vacuum ultraviolet lamp 12 turned on is within a predetermined range.
In this implementation, the power ratio of the short-wave ultraviolet lamp 11 and the vacuum ultraviolet lamp 12 that are turned on is limited through the preset range, so that the total number of free electrons generated when the photocatalyst structural body 2 is irradiated by the two turned-on band ultraviolet lamps is inevitably more than the number of free electrons required for combining the generated ozone, thereby avoiding the harm of ozone to human body to the utmost extent. The preset range may be determined according to an experimental result or a simulation result after determining the structures and positions of the short-wave ultraviolet lamp 11, the vacuum ultraviolet lamp 12, and the photocatalyst structural body 2. Different preset ranges can be set for different air treatment functions, air detection results and other conditions. For example, the power ratio is within a first predetermined range when the concentration of the contaminant is high, and within a second predetermined range when the concentration is low.
In this implementation, when the power of each short wave uv lamp 11 and the power of each vacuum uv lamp 12 in the air treatment device are the same and the powers are fixed, the ratio of the powers can also be expressed as the ratio between the number of short wave uv lamps 11 that are turned on and the number of vacuum uv lamps 12 that are turned on.
In one example of this implementation, the preset range of power ratios of the short wavelength UV lamp 11 and the vacuum UV lamp 12 that are turned on may be 1-50.
In another example of this implementation, the preset range of power ratios of the short wavelength uv lamp 11 and the vacuum uv lamp 12 that are turned on may be 5-10.
In this implementation, the preset range may be further limited to a specific value, i.e. the ratio of the power of the turned-on short-wave ultraviolet lamp 11 to the power of the turned-on vacuum ultraviolet lamp 12 may be directly limited, for example, the set ratio is 2, and then the power of the turned-on short-wave ultraviolet lamp 11 is twice that of the turned-on vacuum ultraviolet lamp 12.
In an implementation manner of this embodiment, a plurality of opening modes may be preset, and the corresponding relationship between different air detection results and the opening modes may be stored; wherein the on mode is used to indicate the respective power or number of the short wave ultraviolet lamps and the vacuum ultraviolet lamps that need to be on.
In this implementation, the open mode may include one or more of the following forms:
turning on all ultraviolet lamps in two wave bands;
turning on a first predetermined number of short wave ultraviolet lamps 11 and a second predetermined number of vacuum ultraviolet lamps 12;
turning on a short-wave ultraviolet lamp 11 with a first preset power and a vacuum ultraviolet lamp 12 with a second preset power;
one or more groups of uv lamps are turned on, wherein each group comprises one vacuum uv lamp 12 and a plurality of short wavelength uv lamps 11.
The above form of the on mode may be used alone, for example, when the on mode is in the form of turning on the short wave ultraviolet lamp 11 of the first predetermined power, and the vacuum ultraviolet lamp 12 of the second predetermined power, the above correspondence relationship may include:
when the air detection result meets a first preset condition, corresponding to a first starting mode: turning on 0.1-2W vacuum ultraviolet lamp 12 and 0.5-20W short wave ultraviolet lamp 11;
when the air detection result meets a second preset condition, corresponding to a second starting mode: turning on 2-5W vacuum ultraviolet lamp 12 and 20-50W short wave ultraviolet lamp 11;
when the air detection result meets a third preset condition, corresponding to a third opening mode: turning on 5-20W vacuum UV lamps 12 and 50-200W short wavelength UV lamps 11.
The above mode of opening may also be used in combination, for example, a set of ultraviolet lamps may be opened when the air detection result satisfies the first preset condition, five short-wave ultraviolet lamps 11 and two vacuum ultraviolet lamps 12 may be opened when the air detection result satisfies the second preset condition, and all ultraviolet lamps of two wavelength bands may be opened when the air detection result satisfies the third preset condition.
If the power of each ultraviolet lamp is constant and the same, the number of the ultraviolet lamps needing to be turned on can be indicated by the turning-on mode, and the power of the ultraviolet lamps needing to be turned on indicated by the first, second and third turning-on modes can be correspondingly converted into the number of the ultraviolet lamps.
If the ultraviolet lamp is a lamp tube with adjustable power, the power can be directly adjusted; if the power is fixed, the power of the turned-on ultraviolet lamps can be adjusted by increasing or decreasing the number of the turned-on ultraviolet lamps.
In this implementation, control circuit 3 opens the ultraviolet lamp of two wave bands according to the air detection result and can include:
the control circuit 3 determines a corresponding starting mode according to the air detection result; and respectively turning on ultraviolet lamps with corresponding power or quantity in two wave bands according to the determined turning-on mode.
In this implementation, when the air treatment function that realizes is different, the air detection result can be different, and the corresponding mode of opening is corresponding different too.
In this embodiment, after turning on the ultraviolet lamp, the control circuit 3 may turn off the turned-on ultraviolet lamp after waiting for a predetermined time period; or after waiting for a preset time, updating the starting mode according to the current air detection result again, and executing any one of the following operations according to the updated starting mode: turning off some of the turned-on UV lamps, or keeping the turned-on UV lamps unchanged, or turning on more UV lamps; until the air detection result reaches a preset standard, the control circuit 3 turns off all the ultraviolet lamps.
In this embodiment, the control circuit 3 may also be configured to turn on or off the dual-band ultraviolet lamp according to a trigger signal such as an operation instruction or a key signal. The operation instruction may be a remote control instruction, an instruction sent by the user through the mobile phone APP, a voice instruction, and the like, for example, the control circuit 3 turns on more ultraviolet lamps in two bands according to the remote control instruction sent by the user to increase the intensity. The key signal may be a signal generated by pressing a physical key or a virtual key by the user, for example, when the control circuit 3 detects that the user presses the key indicating turning off, all the ultraviolet lamps are turned off.
Example 2
The present embodiment provides an air processing apparatus, and based on embodiment 1, the air detection result in this embodiment may be the concentration of different types of detected pollutants.
In this embodiment, the control circuit may be specifically configured to respectively determine whether the detected concentrations of the various types of pollutants exceed corresponding concentration thresholds, determine a corresponding start mode according to the determination result, and correspondingly start the short-wave ultraviolet lamp and the vacuum ultraviolet lamp according to the start mode;
in the embodiment, the number of the ultraviolet lamps to be turned on/the power of the ultraviolet lamps is determined according to the type number of the overproof pollutants, and when the types of the pollutants exceeding the concentration threshold are more, the more serious the air pollution condition is, the more the ultraviolet lamps to be turned on/the more the power of the ultraviolet lamps are, which are indicated by the corresponding turning-on mode.
In this embodiment, the various types of contaminants may include formaldehyde, benzene series, TVOC (Total Volatile Organic Compounds), and the like. Accordingly, the detector may include a formaldehyde detector, a benzene series detector, and a TVOC detector.
In this embodiment, the concentration threshold may be preset, and the concentration thresholds corresponding to different types of pollutants may be different, for example, the concentration threshold of formaldehyde and benzene series may be 0.1 mg per cubic meter, and the concentration threshold of TVOC may be 0.3 mg per cubic meter.
In this embodiment, the number of types of pollutants exceeding the corresponding concentration threshold and the correspondence between the opening modes may be pre-stored, and the control circuit may specifically determine the opening mode according to the determination result and the correspondence, and correspondingly open the ultraviolet lamp of the two bands according to the determined opening mode.
In one implementation of this embodiment, the control circuit determines whether the concentration of each type of pollutant exceeds the concentration threshold value corresponding to that type, and according to the start mode corresponding to the determination result, correspondingly starting the short-wave ultraviolet lamp and the vacuum ultraviolet lamp includes:
if the concentration of each type of pollutant exceeds the corresponding concentration threshold value, the ultraviolet lamp with the two wave bands is started according to a first starting mode;
if the concentration of two or more types of pollutants exceeds the corresponding concentration threshold value, the ultraviolet lamp with the two wave bands is started according to a second starting mode;
if the concentration of only one type of contaminant exceeds the corresponding concentration threshold, the dual band ultraviolet lamp is turned on according to the third on mode.
Wherein the power or number of short wave ultraviolet lamps and/or vacuum ultraviolet lamps that need to be turned on as indicated in the first, second, and third on modes is reduced in sequence.
For example, the power or number of the turned-on vacuum ultraviolet lamps may be kept constant in all three turn-on modes, but all the short-wave ultraviolet lamps are turned on in the first turn-on mode, part of the short-wave ultraviolet lamps are turned on in the second turn-on mode, and only one short-wave ultraviolet lamp is turned on in the third turn-on mode; or the power or the number of the turned-on short-wave ultraviolet lamps can be kept unchanged, and only the power or the number of the vacuum ultraviolet lamps is changed.
For another example, in the first starting mode, all the short-wave ultraviolet lamps and the vacuum ultraviolet lamps are started; the second on mode reduces only the power or number of vacuum ultraviolet lamps that are turned on as compared to the first on mode; the third on mode reduces the power or number of short wavelength ultraviolet lamps on only, or the vacuum ultraviolet lamps, short wavelength ultraviolet lamps on together, as compared to the second on mode.
The above is merely an example, and how to turn on the ultraviolet lamp of the dual band under different turning-on modes can be set by itself, which is not limited in this application.
Wherein the power of the short wave ultraviolet lamp and the vacuum ultraviolet lamp switched on in the first, second and third switching on modes can be set as in example 1; alternatively, all of the short wave uv lamps and the vacuum uv lamps may be turned on in the first on mode; the second starting mode starts the preset partial short-wave ultraviolet lamp and the partial vacuum ultraviolet lamp; the third on mode turns on a single short wave ultraviolet lamp and a single vacuum ultraviolet lamp.
In other implementations, in the case of turning on a portion of the ultraviolet lamps, the specific number of ultraviolet lamps that need to be turned on can be more finely determined further based on the extent to which the contaminants exceed the concentration threshold; for example, if the concentration of two pollutants exceeds the threshold value, but the concentration of the two pollutants is only over 20%, only 20W short-wave ultraviolet lamps and 2W vacuum ultraviolet lamps are turned on, and if the concentration of at least one pollutant is over 50%, 40W short-wave ultraviolet lamps and 4W vacuum ultraviolet lamps are turned on. The specific content of each opening mode and the corresponding relation between the judgment result and the opening mode can be designed and adjusted by self.
In this embodiment, the control circuit may turn off the turned-on ultraviolet lamps at regular time after turning on the ultraviolet lamps of the two bands, or may periodically obtain a determination result as to whether the concentration of each type of current pollutant exceeds the corresponding concentration threshold, and if the number of types of pollutants exceeding the concentration threshold changes, the power or the number of the turned-on ultraviolet lamps may be increased or decreased accordingly.
In one example of this embodiment, the air treatment device includes a two-band ultraviolet lamp, a control circuit, a photocatalyst structure, a formaldehyde detector, a benzene series detector and a TVOC detector; the three detectors are respectively used for obtaining the concentration of formaldehyde, the concentration of benzene series and the concentration of TVOC and sending the formaldehyde, the concentration of the three types of pollutants is respectively compared with the corresponding concentration threshold value by the control circuit, so that whether each type of pollutant exceeds the concentration threshold value is judged, and the ultraviolet lamp with the double wave bands is correspondingly started according to the corresponding starting mode of the judgment result.
In this example, the odor elimination process of the air treatment device is shown in FIG. 4, and includes steps S410-S440:
s410, starting a smell removal function;
s420, a formaldehyde detector, a benzene series detector and a TVOC detector are used for respectively detecting the concentrations of formaldehyde, benzene series and TVOC in the air.
S430, the control circuit respectively judges whether the concentrations of the three pollutants exceed concentration thresholds corresponding to the pollutants of the corresponding types, and the method specifically comprises the following steps:
judging whether the concentration of formaldehyde is greater than 0.1 mg/cubic meter to obtain a first judgment result;
judging whether the concentration of the benzene series is greater than 0.1 mg/cubic meter or not to obtain a second judgment result;
and judging whether the TVOC concentration is more than 0.3 mg/cubic meter or not to obtain a third judgment result.
If the first, second and third judgment results are 'no', the deodorization operation is finished, and all the turned-on ultraviolet lamps are turned off.
S440, correspondingly turning on the ultraviolet lamp with the two wave bands according to the judgment result, which is as follows:
if the first, second and third judgment results are yes, correspondingly turning on the dual-band ultraviolet lamp according to the first turning-on mode, and returning to the step 330;
if two lamps are yes, the two ultraviolet lamps are correspondingly turned on according to the second turning-on mode, and the step S430 is returned.
If only one is yes, the ultraviolet lamps of the two wave bands are correspondingly turned on according to the third opening mode, and the step S430 is returned.
The first, second, and third opening modes may be the same as in embodiment 1.
Wherein, the detector can work continuously, and the judgment is carried out according to the currently detected concentration in the step S430; before returning to step S430, the system may wait for a preset duration, i.e., periodically perform the determination, and when the determination result changes, the number of the turned-on ultraviolet lamps is correspondingly adjusted; for example, currently, all the ultraviolet lamps in the two bands are turned on, but in the latest air detection result, the concentration of formaldehyde is reduced to be lower than the original concentration, and is lower than 0.1 mg/cubic meter, and then part of the ultraviolet lamps can be turned off. The power or amount of the turned-on ultraviolet light is continuously detected and changed until the concentrations of the three pollutants do not exceed the corresponding concentration threshold values, and the odor removal operation is finished. During the deodorization process, if a user stop command is received, the deodorization operation can be ended in advance, and if a user strengthening or weakening command is received, the started ultraviolet lamp can be correspondingly increased or decreased.
