In modern life, the requirement of people on sanitary safety is increasingly raised, and germs existing in living spaces also need to be killed. If the indoor disinfection technology with a large area is good, the safety of the living space is greatly improved.
Medical science shows that high temperature is beneficial to killing bacteria and viruses, and most of the bacteria and viruses have lower survival time in the environment with higher temperature. Just as a person will have a fever after infection, it is actually the immune mechanism of the person, and bacteria and viruses will be inactivated and even killed by making the body temperature higher. Influenza viruses are usually more prevalent in autumn, winter and spring, and the environment is not favorable for the spread of the influenza viruses after the temperature rises in summer. Thus, high temperatures are an effective means of killing bacteria and viruses.
However, the current indoor disinfection technology only can be applied to local areas, such as spraying and wiping disinfection liquid to disinfect the local areas in the room. However, there are also a large number of areas that fall within the dead zone of cleaning: such as those that are not frequently wiped or the suspended ceiling itself that is located high and difficult to clean. Once bacteria or viruses grow in the sanitary dead corners, the sanitary dead corners become the pathogenicity of people.
In addition, ozone and ultraviolet rays can destroy the structure of microorganisms to achieve the aim of disinfection. However, these are also harmful to humans, especially if ozone is present in the space for a certain period of time, whereas uv lamps generate a small amount of ozone during operation. Therefore, after disinfection by ozone and ultraviolet rays, the removal of residual ozone is the biggest problem, and the space can be opened for use after long time is needed for ozone to be decomposed and attenuated.
It is obvious that the prior art has certain defects.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention and the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1 and 4, an embodiment of the present invention provides a comprehensive disinfection room, which has a wall body, an entrance, and a building ceiling that can be completely closed, and includes an ozone input device, a high-temperature thermal radiation ceiling 1, an ultraviolet disinfection lamp 17, and a tail gas purification device; the ozone input device is connected with an air inlet 2 positioned on the ceiling of the building; the high-temperature heat radiation ceiling 1 is laid on a building ceiling; the ultraviolet disinfection lamp 17 is fixedly arranged on a wall or a building ceiling; the tail gas purification device is connected with an exhaust port 3 positioned at the bottom of the wall body.
The invention uses three mutually matched disinfection modes: ozone, ultraviolet and high-temperature disinfection. Ozone lets in indoorly through ozone input device, and ultraviolet ray disinfection lamp 17 radiation ultraviolet ray disinfects, and high temperature heat radiation furred ceiling 1 can produce high fever by far infrared heat radiation and make the interior space disinfect of rising temperature. Wherein, the high temperature can also assist the ozone to be decomposed into oxygen, thereby reducing the residual of the ozone in the indoor space.
Ozone has the advantage of disinfecting without dead angles. However, it is harmful not only to microorganisms such as bacteria and viruses but also to human bodies. Even if all the personnel are dispersed in the disinfection process, ozone residue still possibly exists in the space after the disinfection is finished, the ozone residue is removed by ventilation, extraction, treatment and the like, and even the ozone residue is required to wait for dozens of minutes for decomposition time before the ozone residue can enter.
Ultraviolet rays have the advantage of a large coverage area and are an excellent physical disinfection means. However, the ultraviolet lamp is easy to have dead angles, and the place which is not directly irradiated by the ultraviolet ray cannot be disinfected.
High-temperature disinfection can also be realized without dead angles, but the propagation of temperature needs a certain time, and the energy consumption is higher, if open for a long time will lead to the fact the power consumption and the disinfection cost increase by a wide margin.
The invention applies the advantages and disadvantages of various disinfection modes, firstly, ozone is introduced into the room for disinfection; then, an ultraviolet disinfection lamp 17 is started to radiate ultraviolet rays for disinfection, so as to assist in killing germs on the surfaces of indoor articles; and finally, the high-temperature heat radiation ceiling 1 is opened to heat the indoor space, high-temperature dead-angle-free disinfection is carried out again, the decomposition rate of the ozone is greatly improved under the high-temperature condition by utilizing the unstable chemical characteristic of the ozone, and the ozone is greatly decomposed in the high-temperature disinfection process to avoid excessive residues.
It should be noted that the ozone is followed by ultraviolet disinfection or high-temperature disinfection, and the user can freely select the ozone. The present embodiment details the architecture of a full sterilization room, not the method of sterilization.
The above-mentioned method of performing ultraviolet sterilization first and then performing high-temperature sterilization is undoubtedly a preferred order. The reason is that the optimal wavelength of ultraviolet disinfection is 253.7 nm ultraviolet, and the general household ultraviolet disinfection lamp 17 radiates 253.7 nm ultraviolet and also radiates a part of 184.9 nm ultraviolet, and the 184.9 nm ultraviolet generates new ozone. It is preferable to perform the irradiation sterilization by the ultraviolet ray sterilizing lamp 17 and then perform the high temperature sterilization to help decompose ozone.
Referring to fig. 2 to 4, preferably, the high temperature heat radiation ceiling 1 includes a keel system, a radiation plate 7, a turnover mechanism and a heat source 15; the keel system comprises a hoisting component 8 and a main keel 9, and the main keel 9 is arranged and hoisted below the hoisting component 8; the front surface of the radiation plate 7 is a radiation surface, the heat source 15 is arranged on the back side of the radiation surface and is in heat conduction connection with the radiation surface, and the back side of the heat source 15 is sealed and provided with a heat insulation layer 16; the two sides of the radiation plate 7 are respectively connected with the two main keels 9 in a rotating mode, and the turnover mechanism is in transmission connection with the radiation plate 7, so that the radiation plate 7 can be turned over for 180 degrees under the driving of the turnover mechanism.
The high temperature generated by the heat source 15 can generate uniform heat on the radiation surface of the radiation plate 7, and the uniform heat can be transferred to the indoor space through the forms of heat radiation and heat convection. The temperature of the heat source 15 is generally above 80 ℃, the limit can exceed hundred ℃, and bacteria or viruses are not easy to breed on the surface of the radiation plate 7 naturally. Preferably, the heat source 15 is a heating wire. Meanwhile, through heat radiation and heat convection, the corresponding indoor temperature can be increased to a temperature higher than the normal temperature, and the aim of disinfection is fulfilled.
The keel system plays a role of a bracket, and the radiation plate 7 is not different from the common suspended ceiling when being flat.
The high-temperature heat-radiation ceiling 1 also has two operating modes: a full sterilization mode and a self sterilization mode.
The comprehensive disinfection mode, that is, the disinfection mode of working in cooperation with ozone, the radiation surface faces indoors, heat is released indoors, and the indoor temperature is increased to dozens of degrees centigrade generally. And the temperature is released uniformly in a large area, but not heated locally, so that the whole indoor environment can be changed into a higher-temperature baking environment to carry out large-area indoor disinfection. It is believed that a sustained high temperature environment above 56 ℃ kills most viruses and bacteria.
The self-sterilization mode is to sterilize only the ceiling itself, i.e., the surface of the radiation plate 7. The radiation plate 7 located at a high position in daily life is difficult to clean, so that the radiation plate is a favorable place for breeding bacteria and viruses. Under the self-disinfection mode, through tilting mechanism with radiant panel 7 upset 180, make its radiating surface face back to indoor to the top side, the high temperature of heat source 15 can not just be right to indoor space release this moment, the temperature also can suitably be adjusted down, so indoor can not produce uncomfortable high temperature, belong to the local disinfection scheme that indoor personnel or animal can stay for a long time.
For example, the present invention is applied to a ward of a hospital, and is suitable for use in a self-disinfecting mode in the case where medical staff and patients remain in the ward; when medical care personnel and patients leave the ward, the ozone and ultraviolet rays can be matched to thoroughly disinfect the whole ward, and the comprehensive disinfection mode is suitable for use.
Specifically, the turnover mechanism preferably comprises a motor 10, a synchronous shaft 12, a transmission wheel 11, a turnover wheel 13 and a transmission belt 14; the turning wheels 13 are respectively arranged at the two sides of each radiant panel 7 and fixedly connected with the radiant panels; the driving wheels 11 are rotatably arranged on the main keel 9 and are opposite to all the turnover wheels 13, two driving wheels 11 arranged on the same main keel 9 are positioned at the head end and the tail end of the arrangement direction of the turnover wheels 13, and the motor 10 is in transmission connection with the driving wheel 11 at one end through a synchronous shaft 12; the transmission belt 14 is wound on the transmission wheel 11 on the same main keel 9, is in transmission connection with the transmission wheel 11 and is in transmission connection with all the turnover wheels 13 in the arrangement direction.
The motor 10 drives the synchronizing shaft 12 and further drives the driving wheel 11 to rotate, and the wound driving belt 14 drives the turning wheel 13 to rotate, so that 180-degree turning motion of the radiation plate 7 is realized. In order to prevent slippage between the belt 14 and the drive pulley 11 and the reverse pulley 13 and to prevent transmission from being affected, it is preferable to use a toothed belt 14 that is resistant to high temperatures.
More preferably, the uv disinfection lamp 17 is mounted on the rear surface of the radiation plate 7, directly integrated with the high temperature heat radiation ceiling 1. When the radiation plate 7 is turned over by 180 degrees, the disinfection mode is directly switched.
It should be noted that the specific shape of the panel is not limited, and is generally designed according to the ease of production and the benefit of heat radiation. In addition, the shape of the joining sides of the panels to avoid mutual jamming during the turning movement is preferably an outwardly convex arc.
More specifically, the ozone input device comprises an ozone generator 4 and a fresh air handling unit 5; the air supply end of the fresh air unit 5 is connected with the ozone generator 4 and is communicated with the air inlet 2 of the building ceiling.
The fresh air unit 5 is a main unit arranged in a fresh air system, generally has the functions of filtering air, controlling humidity and the like, and has mature products in the prior art, which are not detailed in detail. In the invention, the fresh air handling unit 5 is mainly used for adjusting the input of ozone and the air circulation after disinfection in cooperation with the introduction of ozone.
Preferably, the exhaust gas purification device comprises an ozonolysis device 6; the inlet of the ozone decomposition device 6 is connected with the exhaust port 3, and the exhaust end of the outlet fresh air unit 5 of the ozone decomposition device 6 is connected.
The ozone treatment method is various, and for example, a pyrolysis method, an activated carbon adsorption method, a chemical absorption method, a chemical catalytic decomposition method, a aeration dilution method, and the like. The ozonolysis apparatus 6 is not an apparatus for carrying out ozonolysis treatment by using one or more of the above-mentioned methods, but belongs to another research direction in the prior art, which is not the subject of the present invention, and is not described herein again. The high-temperature thermal radiation ceiling 1 of the invention utilizes a high-temperature decomposition method, and is matched with the fresh air handling unit 5 to adjust air circulation, so that the ventilation and dilution of ozone are realized to a certain extent, and therefore, the ozone decomposition device 6 belongs to further auxiliary equipment, and other treatment methods are preferably adopted.
In order to facilitate the temperature control of the heat source 15, it is preferable that a temperature detection module is provided inside the radiation plate 7.
Example two
The embodiment of the invention provides a disinfection method, in particular to a disinfection method of a comprehensive disinfection room in the first embodiment, which comprises the following steps:
s01, emptying the room, closing all the entrances and exits in the room, opening the ozone input device, introducing mixed gas of air and ozone into the room, and standing for 30 minutes or more; meanwhile, the ultraviolet sterilizing lamp is enabled to be opposite to the indoor space, and the ultraviolet sterilizing lamp is started to continuously irradiate the indoor space;
s02, turning off the ultraviolet sterilizing lamp to enable the high-temperature heat radiation ceiling to be right opposite to the indoor space, and turning on the high-temperature heat radiation ceiling to continuously heat the indoor space;
and S03, stopping heating the indoor space, starting a tail gas purification device to absorb and purify residual ozone in the room, and discharging the indoor tail gas out of the room.
Ozone is firstly introduced to carry out all-around dead-angle-free disinfection, and germs can be effectively killed after the disinfection is maintained for more than 30 minutes. After 30 minutes, the decomposition of ozone gradually decreased, but the decomposition of ozone was slow at room temperature.
The sterilization by ultraviolet irradiation is preferably performed simultaneously with the ozone sterilization, and is a sterilization for the surfaces of articles in a room in a wide range. As described in example one, partial wavelength of UV light can cause the indoor oxygen to react to generate new ozone, so that the decomposition of ozone is not obvious.
Finally, high-temperature disinfection is carried out, and high-temperature sterilization of germs is carried out while accelerated decomposition of ozone is promoted. Generally, most of ozone is decomposed into oxygen after 30-60 minutes of high-temperature sterilization. In the step S02, the high-temperature heat radiation ceiling 1 heats the room for 30 minutes or more. Preferably, in the step S02, the high-temperature heat radiation ceiling 1 is heated to a temperature of 50 ℃. This temperature is easy to reach, and the temperature can be reached in the general sauna room, and the ozone decomposition speed is obviously improved.
Further, in the step S01, the ozone concentration of the indoor still standing is 10-20 ppm. The standard concentration of indoor ozone disinfection is achieved, the preparation is easy, the general ozone generator 4 can meet the requirement, and excessive ozone cannot be left.
The comprehensive disinfection room and the disinfection method thereof provided by the invention integrate ozone, ultraviolet rays and high-temperature sterilization, which are not mutually insufficient; the characteristic of ozone and high-temperature dead-angle-free disinfection and the characteristic of large ultraviolet coverage are utilized to sterilize and disinfect, and simultaneously, the high temperature is utilized to assist the decomposition of ozone, so that the residual ozone is reduced. Can improve indoor temperature through the mode of the 15 heat radiation of heat source, disinfect comprehensively to the interior space, also can kill and attach to bacterium and the virus on furred ceiling smallpox surface. Has a self-disinfection mode and a comprehensive disinfection mode. Wherein, the radiation plate 7 that overturns does not conduct heat to the indoor space under the self-sterilizer mode, and the high temperature constitutes the discomfort to the human body when avoiding indoor personnel, adapts to the actual needs of disinfection better. And the disinfection is comprehensive, the efficiency is high, and the time consumption is reasonable.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
