Problems solved by technology

[0008] Second, when it is urgent to use ultraviolet disinfection systems to treat relatively low water quality (such as low-quality sewage from urban sewage treatment plants), a problem arises: many parts of the disinfection system that have been in close contact with sewage will accumulate dirt
[0009] In detail, when the sensor accumulates dirt, the ability of the sensor to detect UV radiation is reduced, the sensitivity of the sensor is reduced, and the operator may miss the signal of a reading (that is, what appears to be a small change in the reading is actually a large change), and in fact one or more radiation sources are no longer functioning
It is therefore questionable to have a cleaning device at the sensor window in the sewage flow, as it would impede the flow of the sewage and become an attachment point for dirt and clogging

Abstract

A ultraviolet radiation sensor system with sterilizer consists of sensor and sterilizer. Sensor is used to test radiation degree of radiation field and response to radiation, the device consists of a window to radiation field, which moves from internal radiation field to external radiation field, when window moves to external radiation field and is connected to sterilizer, and sterilizer starts and removes scale from window. It can be a chemical sterilizer, a mechanical sterilizer or mixed sterilizer.

Description

technical field [0001] The invention relates to a light sensing system, in particular to an ultraviolet radiation sensing system with a sterilizing device. Background technique [0002] Optical radiation sensing devices have been widely used, mainly in ultraviolet radiation sewage disinfection systems. [0003] If the product of a given radiation intensity and the exposure time at this intensity is greater than the minimum dose (expressed in milliwatts per square centimeter), ultraviolet rays can sterilize water by irradiating it and killing microorganisms in the water. According to this principle, the ultraviolet disinfection system disinfects water to meet people's various needs for water. [0004] Typically sewage is passed through a pressurized stainless steel chamber filled with UV radiation for disinfection. The treatment modules in a UV disinfection system are submerged in an open channel in which wastewater is exposed to radiation while pass...
