Description
Technical Field
The utility model belongs to the technical field of space disinfection, concretely relates to gas generation and controlling means who uses ultra-low concentration chlorine dioxide gas as main disinfection factor can realize someone dynamic space disinfection under the environment.
Background
Chlorine dioxide, a well-established broad-spectrum, highly effective fourth-generation green disinfectant, has been widely used in the disinfection, sterilization and deodorization processes in the food industry, medical, pharmaceutical, livestock, aquaculture, drinking water, and public environment fields. Chlorine dioxide has strong adsorption and penetration capacity to the cell wall of bacteria, and does not need the transportation of carrier protein, namely osmose. Once chlorine dioxide permeates into bacterial cells, on one hand, the chlorine dioxide can effectively destroy enzymes containing sulfhydryl groups in the bacteria, on the other hand, after nucleic acid (RNA or DNA) in the bacterial cells is oxidized, the synthesis of microbial protein can be rapidly controlled, electrons are forcibly taken away, and the activity of the microbial protein is lost, so that the anabolism of the bacteria is prevented, and the purposes of disinfection, sterilization and deodorization are achieved. Chlorine dioxide has a very strong inactivation capacity for bacteria, viruses and the like.
Around 2000 years ago, countries have come to the standards of chlorine dioxide concentration limits in spaces. Although slightly different, the human exposure limit standard, i.e., short-time exposure limit (STEL), of 0.3ppm (0.9 mg/m), as defined by the institute for occupational safety and health (NIOSH) is basically followed by countries3) Time weighted Limit (TWA) of 0.1ppm (0.3 mg/m)3). The national occupational health standard GBZ 2.1.1-2007 hazardous factors for workplace hazardous factor occupational contact limiting chemical hazardous factors, which is implemented in 2007 in China, stipulates that the time weighted average allowable concentration of chlorine dioxide is 0.3mg/m at 8 hours/working day and 40 hours/working week3Short time contact toleranceIs 0.8mg/m3. The emergence of the above standard means that the human-computer co-location of chlorine dioxide can be realized under the ultra-low concentration within the limit value, so that the dynamic space disinfection with the ultra-low concentration chlorine dioxide as a sterilization factor becomes possible, and the huge potential application requirements are shown. And compared with the existing passive suction type air disinfection devices such as ultraviolet circulating wind and the like, the ultra-low concentration chlorine dioxide gas can realize active attack, realize comprehensive disinfection of air and object surfaces in a space range in all directions without dead angles, and has natural advantages of no substitution.
However, the currently known methods and devices for disinfecting spaces by using chlorine dioxide gas have some bottleneck problems. In the traditional preparation of chlorine dioxide gas, chlorate and acid are fused and chemically reacted to generate chlorine dioxide. The characteristics of chemical reaction determine that the reaction process is difficult to control, so that the method can generate high-concentration chlorine dioxide gas instantly when in use, and the disinfection under human environment cannot be realized. In order to solve this problem, some patent documents (for example, CN103565828B) propose that chlorite is made into gel, and a sustained release agent is added thereto to slow down the generation rate of chlorine dioxide, thereby achieving a sustained release effect. However, tests prove that the method has a certain slow release effect, cannot be controlled within the limit range of national standards, and once the reaction is started, the reaction cannot be stopped, and only continues to be carried out until the consumption of the chlorite is finished.
With the improvement of the method for producing chlorine dioxide gas, it has been found that chlorine dioxide gas can be released by irradiating a material containing sodium chlorite (aqueous solution, gel, powder, etc.) with ultraviolet rays, and that the gas is generated only during the irradiation and is not generated any more once the irradiation is stopped. Based on this publicized principle, there are patent documents that propose a chlorine dioxide gas disinfection apparatus, and for example, patent document (CN 1272075C, first electrical machinery co., ltd.) proposes that chlorine dioxide gas is generated by using ultraviolet rays as a radiation source and using gel-like sodium chlorite as a generation source in a sustained manner; patent document (CN 102834350B, fortunate pharmaceutical) proposes a device including an ultraviolet irradiation unit, a box, an air supply/discharge unit, etc. which irradiates ultraviolet rays onto a powdery (granular) chemical containing solid chlorite to generate chlorine dioxide gas, and discharges the chlorine dioxide gas to the outside air by an internal fan or an air pump; patent document (FMI, CN 104321137B) proposes a chlorine dioxide gas generating apparatus including a storage tank, an ultraviolet irradiation unit, a ventilation unit, and the like, in which a stable chlorine dioxide solution is used as a generating source. Meanwhile, only individual patent documents have considered the problem of controlling the concentration of chlorine dioxide gas, and for example, patent document (CN 1272075C, first electrical product co.) proposes controlling the gas concentration by adjusting the temperature in a gel holding container; patent document (FMI, CN 104321137B) proposes to control the gas concentration by increasing the surface area of the stable chlorine dioxide solution that is in contact with ultraviolet rays. Although the above attempts can produce certain effects, the strict requirements of the corresponding national standards on the limit of the concentration of chlorine dioxide gas in the environment with people cannot be met.
Therefore, due to the limitations of preparation, storage, transportation, concentration control and the like, although the excellent performance of chlorine dioxide itself has been widely recognized, the application of chlorine dioxide in human environment is still in a more primary stage, and related research results at home and abroad are rare. Although chlorine dioxide is specified in the relevant national standards and industrial regulations for space disinfection, it is not possible to effectively control the gas concentration, and most of the current disinfection methods are recommended to be carried out in an unmanned state in the form of aerosol spray.

The utility model relates to a dynamic space disinfection device for realizing human-computer coexistence, which adjusts the generation rate of chlorine dioxide gas through the power of an ultraviolet lamp, the wavelength of the ultraviolet lamp, the surface area of a chlorine dioxide gel storage tank irradiated by the ultraviolet lamp and the distance between the ultraviolet lamp and the surface of gel in the chlorine dioxide gel storage tank; meanwhile, according to the volume of the space environment and the decomposition and attenuation rule of the chlorine dioxide gas, the air in the space environment keeps circulating flow by controlling the opening time of the ultraviolet lamp and the opening time interval of the ultraviolet lamp and combining the operation of the fan, so that the concentration of the chlorine dioxide gas in the air is always within the safety limit range of the national standard, and the dynamic space disinfection under the manned environment is realized.
The concrete description is as follows:
when chlorine dioxide gas is generated by irradiating the surface of the chlorine dioxide gel with ultraviolet rays, the generation rate of the chlorine dioxide gas is mainly determined by the number of photons emitted from the ultraviolet lamp to excite the chlorine dioxide gas. The number of photons depends on four factors: 1) the power of the ultraviolet lamp; 2) the wavelength of the ultraviolet lamp; 3) irradiating the surface area with chlorine dioxide gel; 4) distance of ultraviolet lamp from gel surface. Wherein the first two factors affect the absolute number of photons emitted by the ultraviolet lamp; the latter two factors primarily affect the number of photons specifically involved in the reaction process.
The original intention of the utility model is to ensure coexistence of human and machine, which means that the concentration of chlorine dioxide gas must be controlled within the range of national standard limit. Therefore, an ultraviolet lamp tube with too high power cannot be adopted, otherwise, the generated photons are too large, high-concentration chlorine dioxide gas can be generated in a short time, and the chlorine dioxide gas is difficult to uniformly diffuse into a space environment by means of the operation of a fan. The relationship between the uv lamp power and the chlorine dioxide gas generation rate under otherwise constant conditions is shown in figure 1.
Preferably, the ultraviolet lamp tube with power in the range of 4-10w can achieve ideal excitation effect, the average value of the generation rate of the chlorine dioxide gas is in the range of 0.6-1.0mg/min, and the chlorine dioxide gas can not cause too high concentration near the air outlet of the fan assembly when being transmitted to the space environment along with the operation of the fan.
When the chlorine dioxide is generated by adopting an ultraviolet irradiation mode, the generation rate of the chlorine dioxide is ensured and the chlorine dioxide cannot be rapidly decomposed under the condition of continuous illumination by considering the light-exposure decomposition characteristic of the chlorine dioxide.
Preferably, the excitation effect of chlorine dioxide gas is best at the ultraviolet wavelength of 253.7nm, and it is verified that the generated gas is pure chlorine dioxide gas under the irradiation of ultraviolet rays with the wavelength, and the loss of the generated chlorine dioxide due to decomposition is lowest.
Considering that the irradiation intensity of the ultraviolet lamp is attenuated with the increase of the irradiation distance, the distance from the ultraviolet lamp tube to the gel surface is not suitable to be too long. Meanwhile, if the ultraviolet lamp tube is too close to the surface of the gel, the heat emitted along with the illumination will evaporate the water on the surface of the gel excessively, so that the gel is cured quickly, and the generation effect of chlorine dioxide gas is affected. Under other conditions, the relationship between the distance from the ultraviolet lamp tube to the gel surface and the generation rate of chlorine dioxide gas is shown in figure 2.
Preferably, when the distance between the ultraviolet lamp tube and the surface of the chlorine dioxide gel is 7-10cm, the balance between the irradiation intensity of the ultraviolet lamp and the released heat can be realized, the chlorine dioxide gas can be stably generated, and the gel can continuously keep a good wet state.
The amount of surface area of the chlorine dioxide gel also affects the rate of generation of chlorine dioxide gas. Under the condition that other conditions are not changed, the two are in a substantially proportional relation, and particularly as shown in the attached figure 3.
Preferably, the surface area of the chlorine dioxide gel is controlled to be 60-130 square centimeters by taking the concentration limit value required by human-machine coexistence as reference and combining the current commercially available chlorine dioxide gel form, mainly taking the round can with the single can weight of 500g as the main part.
Furthermore, in the method provided by the present invention, under the irradiation of the ultraviolet lamp with the wavelength of 253.7nm, the change of the generation rate of the chlorine dioxide gas can be realized by the following several ways: 1) the number of generated photons is changed by changing the power of the ultraviolet lamp; 2) increasing or decreasing the gel irradiation surface area by changing the shape of the chlorine dioxide gel storage container; 3) the distance from the ultraviolet lamp to the surface of the gel is increased or decreased to change the irradiation intensity of the ultraviolet rays reaching the surface of the gel.
The stability and the safety of the concentration of the chlorine dioxide gas in a space range need to be operated by a fan, so that the air in the space environment keeps circulating flow, and the generated chlorine dioxide gas is uniformly diffused into the indoor space. In the process, in order to ensure that the concentration of the chlorine dioxide gas in the air is always within the safety limit range of the national standard, the ultraviolet lamp is required to be turned on or off periodically to realize total amount control on the generated chlorine dioxide gas. Therefore, it is necessary to set the on-time of the ultraviolet lamp and the time interval of the ultraviolet lamp. Further, the setting principle and method of the two will be described below.
1. Duration of opening of ultraviolet lamp tube
The opening duration of the ultraviolet lamp tube is most closely related to the generation rate of chlorine dioxide gas and the volume of the space environment. In the safety limit value regulated in the national standard, chlorine dioxide gas generated at a set speed is diffused into a space environment with a set volume, the required time is the ultraviolet lamp opening time, and the specific calculation formula is as follows:
the ultraviolet lamp is turned on for a time (unit: min) equal to: chlorine dioxide STEL Limit (short-time exposure limit of chlorine dioxide gas, unit: mg/m, specified in national standards)3) Multiplied by the volume in space (unit: m is3) And divided by the chlorine dioxide gas release rate (unit: mg/min)
After the ultraviolet lamp is turned on according to the time calculated by the formula, theoretically, the concentration of the chlorine dioxide gas in the space is just the STEL limit value.
However, chlorine dioxide gas itself is easily decomposed, and chlorine dioxide gas is consumed by microorganisms in the air and organic substances including formaldehyde, TVOC, and the like. Therefore, the actual chlorine dioxide gas concentration in the space environment is necessarily lower than the safety limit value of the national standard, so that the human safety of the invention in the operation process can be fully ensured. The difference relationship between the theoretical value and the actual value is shown in fig. 4.
2. Ultraviolet lamp tube opening time interval
The opening time interval of the ultraviolet lamp tube depends on the attenuation and consumption speed of the chlorine dioxide gas in the application environment. The existing theoretical research result shows that the half-life period of the decomposition of the high-concentration chlorine dioxide gas is between 40 and 50min under the natural light condition, while the attenuation effect is remarkably accelerated under the low-concentration condition and the chlorine dioxide gas can be completely decomposed within 30 to 40 min. Meanwhile, the attenuation characteristic of the chlorine dioxide gas is insensitive to temperature change.

As shown in fig. 6 to 8, the ultraviolet lamp tube 1 is fixed below the lamp holder 2, and the reflector 3 is embedded between the ultraviolet lamp tube and the lamp holder for reducing scattering of the ultraviolet lamp when the ultraviolet lamp is turned on and gathering light energy on the surface of the chlorine dioxide gel; one end of the lamp holder 2 is embedded into the height adjusting guide groove 4, and can be adjusted up and down according to requirements so as to change the irradiation height of the ultraviolet lamp; the limit trigger switch 5 is fixed in the inner wall of the side surface of the box body frame 20, and when the sealing cover 11 is completely opened, the sealing cover 11 can directly contact the limit trigger switch 5; when the limit trigger switch 5 is triggered, the signal is transmitted to the PLC 15, the PLC 15 sends an instruction to start the ultraviolet lamp tube 1 to start irradiation; at this time, since the sealing cover 11 is completely opened, the light source emitted from the ultraviolet lamp 1 can directly irradiate the surface of the chlorine dioxide gel stored in the chlorine dioxide gel storage tank 9, thereby exciting the generation of chlorine dioxide gas.
As shown in fig. 6 to 8, when the ultraviolet lamp 1 is irradiated for a predetermined time, the PLC controller 15 sends a command to cut off the current of the ultraviolet lamp 1 and drive the rotary shaft motor 12 to cover the sealing cover 11. When the sealing cover 11 contacts the sealing cover trigger switch 13, the spindle motor 12 is stopped. At this time, the sealing cover 11 can completely cover the chlorine dioxide gel storage tank 9 to ensure that the chlorine dioxide gel is in a closed space when the sterilization operation is stopped, and the excessive evaporation of the water in the gel due to the continuous operation of the centrifugal fan 7 can be avoided.
As shown in fig. 6 to 8, the storage tank guide groove 10 has a side surface with a curvature corresponding to the chlorine dioxide gel storage tank 9, and when the chlorine dioxide gel storage tank is placed in the apparatus, the position thereof can be completely fixed by the storage tank guide groove 10. The storage tank RFID sensor 16 is located directly below the location where the chlorine dioxide gel storage tank 9 is placed within the tank frame 20. Meanwhile, an RFID chip is attached under the chlorine dioxide gel storage tank 9, and when it is placed in the tank frame 20, information including a product number, a manufacturer, a nominal life, etc. in the chip is read by the storage tank RFID sensor and transmitted to the PLC controller 15. During the operation of the device, the PLC controller 15 may calculate the gel state in real time according to the operation time of the device and display the related information in the OLED liquid crystal display panel 19. The screen RFID sensor 17 is located directly below the location where the HEPA high efficiency screen 14 is placed within the cabinet frame 20. The HEPA high-efficiency filter screen 14 has an auxiliary disinfection function, and strengthens the air disinfection effect by adsorbing particles with larger diameters and other harmful microorganisms in the air. An RFID chip is attached under the HEPA high efficiency screen 14, and when it is placed in the cabinet frame 20, the relevant information in the chip can be read by the screen RFID sensor 17 and transmitted to the PLC controller 15. During the operation of the device, the relevant state information of the HEPA high-efficiency filter screen 14 can be calculated in real time by the PLC 15 and displayed in the OLED liquid crystal display panel 19.
As shown in fig. 6 to 8, the air PM2.5 particulate matter sensor 18 is located at the lower right corner in the box frame 20, and the air inlet panel 6 is located at the rear side and is in the same vertical plane with the HEPA high-efficiency filter screen 14, so as to detect the concentration of particulate matters in the air in real time and send data to the PLC controller 15, and the PLC controller 15 adjusts the rotating speed of the centrifugal fan 7 according to the data, so as to adjust the diffusion rate of chlorine dioxide gas in the space environment under different cleanliness conditions.
As shown in fig. 9, the operation and control flow of the present apparatus are as follows.
1) In this embodiment, an ultraviolet lamp having a wavelength of 253.7nm and a power of 4w is selected as a preferred embodiment of the present invention.
2) In this embodiment, the distance between the ultraviolet lamp tube and the surface of the chlorine dioxide gel is selected to be 8 cm.
3) In contrast to currently available chlorine dioxide gels, the 500g canister is based on a substantially circular canister of 10cm diameter with a surface area of about 78 cm square, so in this example, a gel canister of the same size is still selected. Under the conditions, the actually measured release rate of the chlorine dioxide gas is stabilized within the range of 0.6-0.8mg/min, and the concentration of the air outlet can be ensured to meet the national safety standard.
4) When the device is started, the limit value of the input chlorine dioxide STEL is 0.8mg/m3The release rate of the chlorine dioxide gas is 0.8mg/min, and the volume of the space is input according to the actual use environment. By combining the calculation formula, the value of the opening time of the ultraviolet lamp can be calculated and is just equal to the space volume value. In this example, the uv lamp on time interval was given as 60 minutes, taking into account the appropriate redundancy of chlorine dioxide gas consumption time.
5) After the setting of the running state of the device is finished, the device starts to enter formal running. At the moment, the ultraviolet lamp tube 1 is opened, the chlorine dioxide gel sealing cover 11 is opened, and the centrifugal fan 7 starts to work. The ultraviolet lamp tube 1 irradiates the surface of the chlorine dioxide gel to continuously generate chlorine dioxide gas, and the chlorine dioxide gas is actively released into the air by the operation of the centrifugal fan 7. Under the set ultraviolet lamp irradiation time, the total amount of the released chlorine dioxide is constant, the chlorine dioxide is uniformly diffused in the space environment under the driving of the fan, and the concentration can be kept below the safety limit range.
6) After the device reaches the set irradiation time, the ultraviolet lamp tube 1 is closed and the chlorine dioxide gel sealing cover 11 is closed under the control of the control unit. At this time, the centrifugal fan 7 can still be in a working state, and the wind speed of the centrifugal fan 7 is automatically adjusted according to the value of the PM2.5 particulate matter sensor 18. The centrifugal fan 7 is continuously operated, so that the flow of chlorine dioxide gas molecules in the air can be enhanced, and meanwhile, harmful microorganisms in the air can be further adsorbed, so that the air disinfection effect is enhanced.
7) After a set starting time interval, the chlorine dioxide gas in the air is completely consumed or decomposed. At this time, the ultraviolet lamp 1 is restarted by sending an instruction through the control unit, and the chlorine dioxide gel sealing cover 11 is opened, so that the device starts the generation and diffusion work of the chlorine dioxide gas again according to the set time. The above steps are repeated in a circulating way, so that the concentration of the chlorine dioxide gas in the air is ensured to be always within the safety limit range of the national standard, and the absolute safety to human bodies can be realized. Meanwhile, the sterilization effect can be ensured.
At any time when the device runs, a user can automatically select whether to stop the machine or not according to the condition and the use habit of the space environment. If the shutdown is selected, all the components stop running, and the device is shut down.
As an embodiment of the device, multiple experimental results in multiple space environments show that in the operation mode, the device can ensure that the concentration of chlorine dioxide gas at each monitoring point in the indoor space environment is always 0-0.3mg/m3And the human-computer coexistence requirement can be fully met.
The sterilization effect of the device is verified by a disease prevention and control center in Tianjin, and the killing rate of the staphylococcus albus can reach more than 99.9 percent in a simulation field test according to the air sterilization effect identification test requirement specified in the Ministry of public health of the people's republic of China (2002) edition; in field tests, the killing rate of natural bacteria can reach more than 90 percent, and the relevant requirements of high-level air disinfection are met.
