Background
The ultraviolet C disinfection technology has the characteristics of high efficiency, broad spectrum, low price, long service life, no need of adding any substance and no secondary pollution, is favored in the field of water treatment by the unique superiority in recent years, and is more and more widely applied to the sterilization and disinfection treatment of drinking water, industrial and agricultural, food, production water in the pharmaceutical industry, industrial reuse water, sewage and the like.
However, in the ultraviolet disinfection process, a layer of dirt-like substance is formed on the surface of the glass tube outside the ultraviolet lamp tube due to the fact that the glass tube is immersed in water and contacts with sewage for a long time, the light transmittance of the glass tube is influenced, the light transmittance of the glass tube determines the disinfection efficiency, and different cleaning modes are adopted by equipment manufacturers to guarantee the light transmittance of the glass tube for guaranteeing the disinfection efficiency. The conventional glass tube cleaning mode has the following technical defects more or less, and causes the technical defects of low reliability, serious reduction of light transmittance and the like of the conventional ultraviolet bent glass tube cleaning.
The conventional on-line mechanical cleaning is realized by tightly holding the rubber cleaning ring and the glass tube on the glass tube in an interference fit manner, driving the rubber cleaning ring to move back and forth on the glass tube by an air cylinder or a hydraulic rod, and realizing the cleaning purpose by repeatedly rubbing the cleaning ring and the glass tube. The design method has no inconvenience and low manufacturing cost in clean sewage, but the rubber ring is easy to wear after long-time friction, so that the fit clearance with the glass tube is enlarged to influence the cleaning effect, and if substances which are easy to be incrusted and scale are present in the sewage, the rubber ring is aggravated to wear, and the replacement period of the rubber ring is greatly shortened.
The method comprises the steps of on-line mechanical cleaning and off-line chemical cleaning, wherein the off-line chemical cleaning is added on the basis of the on-line mechanical cleaning. Because the actual sewage quality is complicated, most of sewage usually scales on the glass tube outside the ultraviolet lamp tube, and the stubborn scales attached to the glass tube cannot be removed by replacing a new rubber cleaning ring. Therefore, the device is stopped and the bent frame is lifted out, and then the glass tube is manually cleaned by chemical agents. However, this method requires long time for maintenance and manual cleaning, and the process is time-consuming and tedious, and many projects do not have such maintenance conditions.
The online mechanical and chemical automatic cleaning method comprises the specific steps of storing a cleaning agent in a cleaning cavity, wrapping the surface of a glass tube, enabling the cleaning agent to slowly move on the surface of the glass tube through a driving mechanism, and dissolving scales on the surface of the glass tube by using the chemical cleaning agent to achieve the purpose of cleaning. But the structure is unsatisfactory, the leakproofness is relatively poor, and the washing chamber causes the cleaner to reveal easily and forms secondary pollution, and need regularly add the cleaner to equipment, has invisibly increased artifical intensity of labour, has influenced equipment operating efficiency simultaneously.
