Description

Fluid sterilization equipment

The present invention relates to a sterilization and disinfection equipment, in particular to a fluid sterilization and disinfection equipment that improves fluid treatment efficiency through a simple cavity design.

Existing devices that can process fluids (including gases, liquids, and plasma) often have short processing times, sterilization, disinfection, or incomplete algae inhibition. Common treatment devices, such as the "Ultraviolet Light Coupled Titanium Dioxide Sterilization and Disinfection Device" disclosed in Chinese Patent Publication No. CN108328694A, have only a vertical reactor. The upper and lower parts of the reactor are provided with a water outlet and a water inlet respectively. In addition, an ultraviolet lamp is provided in the reactor and the inner wall of the reactor is provided with a nano-titanium dioxide coating; although the above structure can achieve the purpose of liquid sterilization and disinfection, the liquid stays in the above structure for a short time and cannot achieve effective sterilization or disinfection of the liquid. The purpose.

In order to increase the staying time of the fluid in the processing device to achieve a better processing effect, some structures will modify the inside of the flow channel differently. For example, the Republic of China Patent Publication No. M247214 proposes a labyrinth structure for ultraviolet light sterilization, which includes a blower, a labyrinth structure, and an ultraviolet light tube arranged in the labyrinth structure. The labyrinth structure is interlaced by more than one spacer. It is combined, so that when the air enters the labyrinth structure, the staggered spacers can extend the time that the air is exposed to the ultraviolet light tube and achieve the purpose of sterilization; in addition, a type of ultraviolet photocatalytic oxidation disclosed in Chinese Patent Publication No. CN210237187U Water treatment equipment, which is arranged inside the treatment equipment with multiple waves Shaped or polygonal baffle baffles are connected to form wavy or polygonal corridors, allowing liquid to pass through multiple high-intensity ultraviolet light irradiation areas in a baffled flow mode.

However, although the above structure can use the internal labyrinth or the partition to increase the sterilization time to increase the path length and increase the residence time of the liquid or gas in the device, the overly complex mechanism leads to a significant increase in cost, and there are still difficulties in actual manufacturing.

In addition, some fluid processors that use ultraviolet light C (UVC) mostly focus on the flow channel design, which not only narrows the pipeline, but also makes it difficult to manufacture and clean, and the cost also increases.

Today, the inventors have made improvements in view of the fact that the above-mentioned existing fluid sterilization devices still have many shortcomings in actual implementation and use, so with the assistance of their rich professional knowledge and years of practical experience, they have made improvements, and developed the present invention accordingly. , Its purpose is to provide a fluid treatment device that can be installed on a target device, with a simple structure design to improve the efficiency of fluid sterilization and disinfection.

In order to achieve the above-mentioned implementation objectives, the present inventor proposes a fluid sterilization and disinfection equipment, which includes a cavity with an inlet, a flow channel and an outlet for a fluid to pass through; at least one spoiler mechanism is arranged in the flow channel, Entrance or a combination of the two; a quartz sleeve, which is axially arranged in the cavity; and at least one light source module, which is axially arranged in the quartz sleeve, and is equipped with a circuit board and a plurality of UVC LED light processors To irradiate the fluid.

In an embodiment of the present invention, the turbulence mechanism has a plurality of through holes and a plurality of guide rails to change the flow direction of the fluid and generate turbulence.

In an embodiment of the present invention, the spoiler mechanism has a plurality of mesh shapes.

In an embodiment of the present invention, the turbulence mechanism has a plurality of blades and a plurality of guide rails, and the plurality of blades are arranged at an inclination angle to guide the flow.

In this way, the present invention uses a simple design of the flow turbulence mechanism to make the fluid enter the cavity from the inlet After that, turbulence is generated and flows around the quartz sleeve, which increases the path and residence time of fluid flow, and achieves the effect of fluid sterilization and disinfection.
