Description

Technical Field

[0001] The invention relates to a tap water treatment device, in particular to a disinfection and sterilization device for secondary tap water supply and community direct drinking water system, belonging to the technical field of water treatment equipment. Background Art

[0002] With the rapid development of urbanization, the number of high-rise buildings in my country is increasing. As we all know, a secondary water supply device must be installed in the water supply system of high-rise buildings, otherwise people living in high-rise buildings will not get normal water pressure, which directly affects the quality of life of high-rise residents. Therefore, the secondary water supply device of tap water is a necessary and extremely important key facility to ensure the water supply of residents in high-rise buildings. Although the existing secondary water supply device of tap water in high-rise buildings can realize secondary pressurized water supply, the water tank in the secondary water supply system is connected to the outside world. The water tank and the water pipeline connected to it are in a humid and water-containing environment for a long time, which is very conducive to the growth and reproduction of bacteria, viruses and harmful microorganisms. At the same time, the water tank and the water pipeline materials themselves will release harmful substances. Therefore, the water body in the secondary water supply system must be disinfected and sterilized to disinfect various bacteria, viruses and harmful microorganisms that are bred, so as to ensure that the water quality of the secondary water supply meets the national standards. At present, chemical methods such as sodium hypochlorite are usually used to disinfect and sterilize water in secondary water supply systems. Such disinfection and sterilization methods are not only costly, but also have unstable and incomplete sterilization effects, and also produce harmful by-products such as halogenated hydrocarbons.

[0003] As people's living standards improve, they have higher and higher requirements for the quality of domestic water. Many communities have added direct drinking water supply systems, which are achieved by adding water purifiers and drug sterilization methods. The effect is also unstable, and people dare not drink directly. Therefore, it is urgent to strengthen the upgrade of secondary water supply systems and direct drinking water supply systems. How to stably, thoroughly and effectively solve the disinfection and sterilization problems in the secondary water supply system and the community direct drinking water system has become the most concerned issue in high-rise building communities, and it is also a difficult problem that the tap water industry is eager to solve. Summary of the invention

[0004] The purpose of the present invention is to provide a pulsed strong light disinfection and sterilization device for tap water secondary water supply and community direct drinking water system. It adopts a pulsed strong light sterilization lamp group to irradiate the water body flowing through, so as to stably and thoroughly sterilize the water body with high efficiency, eliminate harmful microorganisms, and ensure that the water body in the secondary water supply and community direct drinking water system is non-toxic, sterile, hygienic and safe. It can solve the problem of disinfection and sterilization of water body in the secondary water supply and community direct drinking water system.

[0005] The present invention adopts the following technical scheme: A pulsed strong light disinfection and sterilization device for secondary water supply of tap water and direct drinking water system of community comprises a water inlet joint, a water storage tank, a water outlet joint and a pulsed strong light sterilization lamp group. The water inlet joint and the water outlet joint are arranged on the water storage tank at intervals, the water inlet joint and the water outlet joint are communicated with the inner cavity of the water storage tank, and the pulsed strong light sterilization lamp group is arranged between the water inlet joint and the water outlet joint. All the irradiated parts of the pulsed strong light sterilization lamp group are installed in the inner cavity of the water storage tank in a water-sealed and insulated manner. The wavelength of the sterilization and disinfection spectrum emitted by the pulsed strong light sterilization lamp group is 200-1100nm.

[0006] Furthermore, the pulsed strong light sterilization lamp group is horizontally arranged in the inner cavity of the water storage tank.

[0007] Furthermore, the pulsed strong light sterilization lamp group is vertically arranged in the inner cavity of the water storage tank.

[0008] Furthermore, the lamp tubes in the pulsed strong light germicidal lamp group are linear lamp tubes.

[0009] Furthermore, the lamp tubes in the pulsed strong light germicidal lamp group are U-shaped lamp tubes, ring-shaped lamp tubes or spiral lamp tubes.

[0010] Furthermore, the water inlet joint is arranged on the bottom side of the water storage tank body, and the water outlet joint is arranged on the top surface of the water storage tank body.

[0011] Furthermore, the water inlet joint and the water outlet joint are respectively arranged at two ends of the water storage tank body.

[0012] Furthermore, the number of distribution intervals between the linear lamp tubes in the pulsed light germicidal lamp group is 3 to 1000 mm.

[0013] Furthermore, a water flow homogenization structure is provided between the water inlet joint and the pulsed strong light sterilization lamp group. The water flow homogenization structure is a porous homogenization plate provided between the bottom of the inner cavity of the water storage tank and the water inlet joint. The material of the porous homogenization plate is a copper-based catalyst alloy with anti-scaling function. Its components are eight metal elements: Cu, Ni, Zn, Sn, Pb, Fe, Sb, and Mn. The weight percentage of each component is: Cu 40%-70%; Ni 5%-20%; Zn 10%-35%; Sn 5%-30%; Pb 0.5%-20%; Fe 0.1%-8%; Sb 0.01%-2%; Mn 0.05%-5%. Each component is synthesized by high temperature into a kind of catalyst along the S 100The columnar crystal alloy with directional growth of crystal axis can not only fragment the water flow evenly, prevent the accumulation of water bacteria, which will affect the thoroughness of sterilization, but also effectively prevent the formation of scale and dissolve scale, ensure the stability and anti-scale performance of the secondary water supply system and the direct drinking water supply system, increase the service life of the invention, and reduce the cost of use and maintenance. The anti-scale function of this copper-based catalyst alloy material with anti-scaling function is described in detail in the authorized invention patent CN200810024432.0. The smaller the pore size on the porous homogenizing plate, the greater the density and the better the homogenizing effect.

[0014] Furthermore, the pulsed strong light sterilization lamp group includes a linear lamp tube, a lamp electrode and an end seal. Lamp electrodes and end seals are respectively provided at the two ends of the linear lamp tube. The end seals connect the lamp electrodes watertightly, so that the pulsed strong light sterilization lamp group has a waterproof function. The pulsed strong light sterilization lamp group is fixedly installed on the water storage tank.

[0015] Furthermore, the pulsed strong light sterilization lamp group includes a U-shaped lamp tube, a lamp electrode and an end seal. Lamp electrodes and end seals are respectively provided at the two ends of the U-shaped lamp tube. The end seals connect the lamp electrodes watertightly, so that the pulsed strong light sterilization lamp group has a waterproof function. The pulsed strong light sterilization lamp group is fixedly installed on the water storage tank.

[0016] The pulsed light sterilization lamp uses high-intensity and wide-spectrum pulsed light released instantly, including ultraviolet light, visible light and infrared light, to disinfect bacteria through multiple effects such as photothermal and photochemical effects. The wavelength of the pulsed light emitted by the pulsed light sterilization lamp group is 200-1100nm. The full-spectrum light in this wavelength can quickly destroy the DNA or RNA structure of microorganisms, making them lose their ability to survive. The energy of the pulsed ultraviolet light generated by the pulsed light sterilization lamp group is more than 3000 times that of traditional ultraviolet light, and the instantaneous intensity can reach megawatt level, instantly generating extremely high-energy visible light, ultraviolet light and multiple electromagnetic waves to produce a polymerization effect; the pulsed light has high penetration and can efficiently and thoroughly sterilize the inside of the liquid; the sterilization efficiency of the pulsed light is as high as 99.999% or more; at the same time, the energy consumption of the pulsed light is very low, saving 80%-90% energy compared with traditional ultraviolet lamps; the pulsed light control is flexible and can be turned on and off at any time; the pulsed light sterilization does not use any chemical reagents, and is pollution-free and residue-free.

[0017] The method of using the present invention is as follows: the present invention is installed at the water outlet of the tap water in a secondary water supply station or a community direct drinking water system. When the water to be treated flows into the inner cavity of the water storage tank from the water inlet joint, the whole process is irradiated by the pulsed strong light emitted by the pulsed strong light sterilization lamp group, and the bacteria, viruses and microorganisms in the water body are completely killed or decomposed by the pulsed strong light. If a water flow homogenization structure and a secondary filtration structure are set at the front end of the water inlet joint, the input water flow can be homogenized and the bacterial agglomerates stored in the water can be broken up to prevent the bacterial agglomerates in the water from being missed due to being too large, and the cleanliness of the secondary water supply can be further improved. The water treated by the present invention can meet the direct drinking water standards of being non-toxic, sterile, hygienic and safe, and can be drunk directly. The present invention is an ideal supporting technology for upgrading and transforming secondary water supply systems or community direct drinking water supply systems.

Figure 5~Figure 6 shown.

[0033] Embodiment 4: This is the third structural form of the present invention. Different from the vertical structure of embodiments 1-3, this is a horizontal structure. This pulsed strong light disinfection and sterilization device for secondary water supply of tap water and direct drinking water system of community, such as Figure 7~Figure 8 As shown, it includes a water inlet joint 1, a water storage box 2, a water outlet joint 3 and a pulse strong light sterilization lamp group 4. The water inlet joint 1 and the water outlet joint 3 are arranged on the water storage box 2 at intervals. The water inlet joint 1 and the water outlet joint 3 are both communicated with the inner cavity of the water storage box 2. The pulse strong light sterilization lamp group 4 is arranged between the water inlet joint 1 and the water outlet joint 3. All the pulse strong light sterilization lamp group 4 is installed in the inner cavity of the water storage box 2 in a water-tight and insulated manner.

[0034] In this example, the water storage tank body 2 is a cylindrical structure, and the pulsed strong light sterilization lamp group 4 is composed of 16 straight pulsed strong light sterilization lamp tubes evenly distributed in a row on the same circumference. All the pulsed strong light sterilization lamp tubes are arranged in parallel and at intervals in the inner cavity of the water storage tank body 2. All the pulsed strong light sterilization lamp tubes are arranged horizontally and parallel to the axis of the cylindrical water storage tank body 2. The two ends of the straight pulsed strong light sterilization lamp tubes are water-tightly installed on the left and right side walls of the water storage tank body 2, and the water inlet joint 1 and the water outlet joint are respectively arranged on the left and right sides of the water storage tank body 2.

[0035] Embodiment 6: The difference from Embodiment 5 lies in the structure of the water storage tank body 2, wherein the water storage tank body 2 comprises an outer cylinder body 21, an inner cylinder body 22 and a water overflow notch 23, the outer cylinder body 21 and the inner cylinder body 22 are coaxially distributed, the water overflow notch 23 is arranged on the side wall below the outer circle of the inner cylinder body 22, and the linear pulsed strong light sterilization lamp tube is circumferentially distributed between the outer cylinder body 21 and the inner cylinder body 22, the water inlet joint 1 is connected with the inner cavity of the inner cylinder body 22, and overflows from the bottom to the top from the water overflow notch 23 into the sterilization cavity enclosed by the outer cylinder body 21 and the inner cylinder body 22, and the water after sterilization and disinfection is discharged from the water outlet joint 3.

[0036] In Example 6, the water outlet joint 3 can be set on the outer cylindrical side wall of the outer cylinder 21, and the distance from the water inlet joint 1 should be greater than 50% of the axial length of the outer cylinder 21, or it can be set on the right side surface of the outer cylinder 21.

[0037] The overflow water gap 23 starts from the end close to the water inlet joint 1 , and its opening length along the axial direction can be set arbitrarily. The gap cross section is greater than or equal to the water inlet cross section of the water inlet joint 1 .

[0038] Embodiment 7: The water storage tank body 2 includes an outer cylinder body 21 and an inner cylinder body 22, and the outer cylinder body 21 and the inner cylinder body 22 are coaxially distributed. The linear pulsed strong light sterilization lamp tube is circumferentially distributed between the outer cylinder body 21 and the inner cylinder body 22. The water inlet joint 1 and the water outlet joint 3 are both connected to the annular inner cavity surrounded by the outer cylinder body 21 and the inner cylinder body 22. The water inlet joint 1 and the water outlet joint 3 are respectively arranged on both sides of the annular inner cavity. The water to be treated is input from the water inlet joint and discharged from the water outlet joint 3 after sterilization.

[0039] Embodiment 8: The inner cylinder 22 in Embodiment 6 is removed, and the water body can also be sterilized and disinfected, but the sterilization and disinfection effect is slightly worse.

[0040] The lamp tubes in the pulsed strong light germicidal lamp set 4 in the above examples are spiral lamp tubes or ring lamp tubes.

[0041] In the above examples, the setting positions of the water inlet joint 1 and the water outlet joint 3 can also be changed, as long as they are located at different positions of the water storage tank 2, so that the pulsed light sterilization lamp group 4 is set between the water inlet joint 1 and the water outlet joint 3, ensuring that the pulsed light sterilization lamp group 4 can perform full-width light sterilization on the water flowing through the water storage tank 2.

[0042] The number of distribution intervals between the linear lamp tubes 41 in the pulsed light sterilization lamp group 4 is 3 to 1000 mm.

[0043] An impurity filter or a water purifier is provided at the water inlet end of the water inlet connector 1 .

[0044] The spectral wavelength emitted by the pulsed strong light germicidal lamp group 4 is 200nm-1100nm.

[0045] In the above embodiments, if an impurity filter or a water purifier is provided at the water inlet end of the water inlet connector 1, it can both disinfect and remove impurities, and the water quality will be better.

[0047] When secondary water supply is needed, the pulsed strong light sterilization lamp group 4 is turned on and then the booster pump is turned on. The water in the water storage tank is sucked out by the booster pump and then sent to the water storage tank from the water inlet joint of the present invention. Since the pulsed strong light sterilization lamp group 4 is added in the secondary water supply pipeline, the water flowing through the water supply pipeline is irradiated by the pulsed strong light sterilization lamp group 4 with a wavelength of 200-1100nm full spectrum light, which can effectively destroy the DNA and RNA structure of bacteria, viruses and other microorganisms in the water, making them lose their reproduction and survival ability. Since the pulsed strong light has high energy density and broad-spectrum sterilization characteristics, it can quickly kill a variety of bacteria, viruses, algae and other microorganisms in the water body, and the sterilization rate can reach more than 99.9%. The present invention can effectively solve the problem of thorough disinfection of bacteria, viruses, harmful microorganisms, etc. that breed in secondary water supply and community direct drinking water systems, and has broad market application prospects.

[0048] The present invention has a simple structure and a wide range of application scenarios. It can be directly installed in the secondary water supply system and can also be used in the community tap water direct drinking system. It can also be designed to be miniaturized and suitable for water system disinfection in enterprises, institutions, guesthouses, and other places. It is also applicable to aquaculture, animal breeding and other places. The present invention is easy to implement, does not require large-scale transformation of the secondary water supply pipeline, and the user's usage habits do not need to be changed. The operation is simple and convenient, the sterilization effect is stable and thorough, and the pulsed strong light sterilization and disinfection technology is used. The sterilization is fast and thorough. Compared with traditional large-scale high-temperature sterilization equipment, the energy consumption is greatly reduced, which reduces the user's use cost.

[0049] There are many implementation methods of the present invention, which are not listed here one by one. As long as a pulse strong light sterilization lamp group 4 is set in the water supply pipeline to disinfect and sterilize the water flowing through it, all solutions fall within the protection scope of the present invention.
