Problems solved by technology

During the use of existing ultraviolet sterilizers, the quartz casing is often damaged due to the "bridging water hammer" or "water hammer effect" caused by backflow. The rupture of the quartz casing will cause the ultraviolet rays to fail to work normally and affect water quality and safety. At the same time, if the quartz casing is broken, debris may enter the water, seriously affecting the safety of water supply

Abstract

The invention provides anti-impact protection apparatus of an ultraviolet sterilizer. The apparatus comprises a metal cylinder and an ultraviolet lamp with a quartz sleeve, the metal cylinder is provided with a water inlet and a water outlet, a pipeline connected with the water outlet is provided with a check valve, and a pressure sensor, a programmable logic controller (PLC), an intelligent controller and a magnetic switch device are arranged on the metal cylinder. According to the apparatus, the pressure sensor and the PLC are used for identifying whether backflow or water hammer occurs or not; when the pressure value exceeds a set range, the PLC sends a signal to the intelligent controller to control the closing of the magnetic switch device; and when the pressure is recovered to the set range, the PLC sends a signal to the intelligent controller to control the opening of the magnetic switch device. According to the anti-impact protection apparatus, the quartz sleeve can be effectively protected, so that the situation that the ultraviolet sterilizer cannot normally work and safety of water quality is influenced due to the fact that the quartz sleeve is broken is avoided.

Description

technical field [0001] The invention belongs to the field of ultraviolet sterilizers in water supply systems, in particular to an anti-shock protection device for ultraviolet sterilizers. Background technique [0002] Ultraviolet sterilizer is widely used and is of high value in water treatment. It destroys and changes the DNA structure of microorganisms through the irradiation of ultraviolet light to achieve the purpose of sterilization; ultraviolet sterilizer is a purely physical disinfection method, which is simple, convenient, widely used With the advantages of high spectrum efficiency, no secondary pollution, easy management and automation, with the introduction of various new designs of ultraviolet lamps, the scope of application of ultraviolet sterilization is also expanding. The enclosed UV sterilizer is a pressurized ultraviolet sterilizer, which usually uses a metal cylinder and an ultraviolet lamp with a quartz sleeve to seal the sterilized water. During the use ...
