Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

As shown in fig. 1: a pulse ultraviolet fluid sterilizer comprises a cavity 1, the cavity 1 can be enclosed by a rectangular box body, the cavity 1 is connected with fluid inlets and

outlets

11 and 12, and a pulse ultraviolet light source 2 is arranged in the cavity 1. In order to purify the fluid more fully, it is preferable that the pulsed ultraviolet light source 2 is arranged along the fluid flow direction to sterilize the fluid to be sterilized by an over-flow method.

Preferably, the pulsed uv light source 2 may be a pulsed uv xenon lamp, and more preferably a spherical pulsed uv xenon lamp, so that the fluid can be sterilized and disinfected more fully by the extended path. Of course, the shape of the pulse ultraviolet xenon lamp can be a straight tube type, a U type or a spiral type besides the spherical pulse ultraviolet xenon lamp. The spherical pulse ultraviolet xenon lamp is more sufficient when contacting water, and the disinfection effect is better.

When the ultraviolet xenon lamp is arranged, one part of an electrode 21 of an ultraviolet light source 2 is arranged in the cavity 1, the other part of the electrode 21 is arranged outside the cavity 1, and a sealing ring 3 is arranged at the part of the electrode 21, which is contacted with the outer wall of the cavity 1, so that fluid leakage is prevented.

In order to make the purifying effect better, the inner wall of the cavity 1 is distributed with photocatalyst. Preferably, the photocatalyst sinters the titanium dioxide and the noble metal nanoparticles on the porous nickel-based metal mesh or directly attaches the titanium dioxide and the noble metal composite nanoparticles on the inner wall of the cavity in a sintering mode. When the photocatalyst is formed by sintering titanium dioxide and precious metal nano particles on the porous nickel-based metal net, the photocatalyst is preferably formed into an integral cage shape and can be detachably placed on the inner wall of the cavity, and of course, the photocatalyst can be independently attached to the inner wall of the cavity according to needs.

Preferably, the chamber of the sterilizer is made of stainless steel material. Thus, the ultraviolet rays emitted by the pulse ultraviolet light source irradiate on the inner wall of the cavity to activate the photocatalyst, and the photocatalyst and oxygen molecules, water molecules and pollutants in the fluid flowing through the photocatalytic net generate catalytic reaction. The specific reaction is as follows: catalysts (mainly titanium dioxide and other photoactive catalysts) form electron-hole pairs under the action of ultraviolet light, wherein the holes have a strong oxidizing effect and the electrons have a strong reducing effect. The holes oxidize and decompose organic molecules and microorganisms adsorbed on the catalyst, thereby exerting a more preferable sterilization and purification effect and forming an oxidative hydroxyl group. The electrons promote oxygen molecules and water molecules to form negative oxygen ions and hydroxyl radicals with oxidation activity. The hydroxyl and negative oxygen ions flow into the water stream with the fluid, and further preferably act to disinfect and purify organic contaminants and microorganisms in the fluid to a greater extent. If the ultraviolet light source comprises short-wave ultraviolet rays with the wavelength of below 260nm, the effect is better.

The photocatalyst formed by adopting the sintering mode has surface activity, and microorganisms cannot be attached to the photocatalyst for propagation, so that the photocatalyst also plays a role in preventing the mass propagation of the microorganisms during the cavity water storage period, and the difficulty is reduced for the instant disinfection during water outlet.

Just because the utility model provides an above-mentioned advantage of sterilizer is particularly suitable for opening promptly and uses the fluid system, and the advantage that is showing lies in can be high-efficient abundant carrying on the fluid disinfection and sterilization, if the straight water dispenser of being particularly suitable for straight water system. In order to make the control of the disinfection process more convenient, the pulse ultraviolet fluid disinfector is arranged on the water delivery pipeline of the direct drinking machine or the outlet of a running water switch (such as a tap). And the pulsed ultraviolet fluid disinfector is in linkage relation with the fluid switch, when the fluid switch is turned on, the pulsed ultraviolet disinfection equipment is started instantly to disinfect the fluid flowing through the cavity of the pulsed ultraviolet fluid disinfector. The effect of inhibiting the growth of microorganisms can be achieved during the water storage period.

According to the pulse ultraviolet fluid sterilizer, the utility model also provides an embodiment of the fluid system that is ready to use immediately, including the pulse ultraviolet fluid sterilizer of any above-mentioned technical scheme.

In order to facilitate the disinfection process, the pulsed ultraviolet fluid disinfector is in linkage relation with the fluid switch, when the fluid switch is turned on, the pulsed ultraviolet disinfection equipment is started instantly to disinfect the fluid flowing through the cavity of the pulsed ultraviolet fluid disinfector. The pulsed ultraviolet fluid disinfector is arranged on an output port or an output pipeline of the fluid system. The fluid system is a direct drinking water system, preferably a direct drinking water machine.

In summary, taking direct drinking machine application as an example, the pulse ultraviolet fluid sterilizer provided by the utility model has the main advantages that when being used in the fluid system that is ready to use immediately:

(1) can be used immediately after being opened, and has low cost.

If the device is used on equipment for directly drinking water, whether the device can be used immediately after being opened or not is an important factor. Because the drinking water system can not continuously discharge water, the drinking water system is generally irregularly and frequently switched on and off. If the ultraviolet mercury lamp is used for disinfection, the mercury lamp needs to be preheated, and the time for achieving the disinfection effect is long, so that the over-flow type work is difficult to realize, and the machine can not be shut down for a long time only so as to maintain the disinfection effect. This significantly increases the power consumption of the drinking water system, which also results in a shorter life of the mercury lamp, which is replaced in about 1000 hours or less, or in less than three months (20 hours per day). The pulse ultraviolet xenon lamp has no problems, can be linked with a water outlet switch, can be disinfected when water flows out, can be stopped immediately when the water flow stops, and can also ensure the disinfection effect. The life of a pulsed lamp is as long as 2 billion times, assuming a high frequency use: each time of water discharge lasts for one minute, water discharge is performed 20 times per hour, the operation is performed for 20 hours a day, the light source flickers 10 times per second, and the flickering is calculated to be required 10 times by 60 times by 20 times per day as 24 ten thousand times. The replacement period of the pulse xenon lamp is 2 hundred million times/24 ten thousand times (each day) and 833 days. Therefore, even in the case of frequent use, the consumable replacement period is as long as several years, and the cost of the whole system is controllable.

(2) Small size, low power, and easy integration

The spherical flash lamp is adopted, the diameter is only a few millimeters, the power supply can also realize miniaturization, and the spherical flash lamp is smaller and smaller than a mercury lamp with the same effect, and is beneficial to being applied to household appliances.

(3) Wide spectrum, wide application and high penetrability

Because the spectrum is wider than that of mercury lamps and LEDs, and the intensity is higher, the effect of killing different microorganisms is obvious. And because the low-pressure ultraviolet mercury lamp and the ultraviolet LED have single wavelength, the killing effect on some microorganisms is not obvious, longer time or larger dosage is needed, and even the microorganisms cannot be killed completely, so the using effect is influenced.

(4) Non-toxic and harmless

Because the pulse xenon lamp used by the utility model does not contain any harmful component, the pulse xenon lamp can be applied to the direct disinfection of drinking water systems with reassurance. The mercury lamp contains heavy metal, so that once the mercury lamp is broken in water, the mercury lamp can pollute water and harm health.

Ultraviolet disinfection is an existing technology, and a larger straight tube xenon lamp is applied to a water purification and sewage disinfection system for some cases. But the application form and the product of using miniaturized spherical ultraviolet xenon lamp to carry out the direct disinfection of small flow drinking water overflow formula have not been seen yet, the utility model has the outstanding substantive characteristics.
