Description

Fluid sterilization and disinfection equipment

Technical Field

The present invention relates to a fluid sterilization apparatus, and more particularly, to a fluid sterilization apparatus with a simple chamber design to improve fluid processing efficiency.

Background

The existing devices capable of processing fluid (including gas, liquid and plasma) have the defects of short processing time, and incomplete functions of sterilization, disinfection or algae inhibition. A common treatment device, such as an ultraviolet light coupling titanium dioxide sterilization and disinfection device disclosed in chinese patent publication No. CN108328694A, has a structure including a reactor arranged vertically, a water outlet and a water inlet respectively disposed at the upper and lower parts of the reactor, an ultraviolet lamp disposed in the reactor, and a nano titanium dioxide coating disposed on the inner wall of the reactor; although the structure can achieve the aim of sterilizing and disinfecting liquid, the stay time of the liquid in the structure is short, and the aim of effectively sterilizing or disinfecting the liquid cannot be achieved.

In order to increase the residence time of the fluid in the processing device and achieve better processing effect, some structures may improve the interior of the flow channel differently. For example, taiwan patent publication No. M247214 proposes a labyrinth structure for ultraviolet sterilization, which comprises a blower, a labyrinth structure and an ultraviolet lamp tube disposed in the labyrinth structure, wherein the labyrinth structure is formed by combining more than one interlaced spacers, so that when air enters the labyrinth structure, the time for exposing the air to the ultraviolet lamp tube can be prolonged due to the interlaced spacers, thereby achieving the purpose of sterilization; in addition, chinese patent publication No. CN210237187U discloses an ultraviolet catalytic oxidation water treatment apparatus, wherein a plurality of wave-shaped or polygonal baffle plates are disposed inside the treatment apparatus to form wave-shaped or polygonal galleries, so that liquid can pass through a plurality of high-intensity ultraviolet irradiation regions in a baffled flow manner.

However, although the above structure can increase the sterilization time by using the inner labyrinth or partition plate to increase the path length and increase the residence time of the liquid or gas in the apparatus, the cost is greatly increased due to the complicated mechanism, and it is still difficult to actually manufacture the apparatus.

In addition, some fluid processors using ultraviolet c (uvc) are mostly focused on the flow channel design, which not only narrows the channel, makes the fabrication and cleaning difficult, and increases the cost.

Disclosure of Invention

The present invention is made in view of the above-mentioned shortcomings of the conventional fluid sterilization apparatus, and aims to provide a fluid processing apparatus capable of being installed on a target apparatus to improve the sterilization efficiency of fluid by a simple structure design.

In order to achieve the above-mentioned objectives, the present invention provides a fluid sterilization and disinfection apparatus, which includes a chamber having an inlet, a flow channel and an outlet for a fluid to pass through; at least one turbulence mechanism arranged in the flow channel, the inlet or the combination of the flow channel and the inlet; the quartz sleeve is axially arranged in the cavity; and at least one light source module axially arranged in the quartz sleeve and provided with a circuit board and a plurality of UVC LED light processors for irradiating fluid.

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

In an embodiment of the present invention, the turbulent flow mechanism has a plurality of meshes.

In an embodiment of the invention, the spoiler 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.

Therefore, the invention uses the simply designed flow disturbing mechanism to generate turbulent flow after the fluid enters the cavity from the inlet and flows around the quartz sleeve, thereby increasing the flow path and the retention time of the fluid and achieving the sterilization and disinfection efficiency of the fluid.
