Description
Technical Field
The invention belongs to the technical field of disinfection treatment equipment, and particularly relates to an ultraviolet laser sterilizer system.
Background
The conventional ultraviolet sterilizer uses an ultraviolet mercury lamp as a light source, and uses 253.7nm ultraviolet rays discharged by mercury vapor in a lamp tube as a main spectral line to sterilize the drinking water. The conventional ultraviolet sterilizer mainly comprises a mercury vapor lamp tube, a quartz tube, a cavity, an electronic ballast and accessories thereof, and the large and medium ultraviolet sterilizer is also required to be provided with accessories such as an ultraviolet intensity sensor, a cleaning system and the like. Ultraviolet ray that current ultraviolet disinfector used mercury vapor lamp sent need pierce through the quartz capsule after to the water all around the radiation disinfection of quartz capsule, but ultraviolet ray can progressively attenuate with water contact after permeating the quartz capsule, therefore ultraviolet disinfection effective distance is limited, and the disinfection effect must guarantee longer contact time under the certain circumstances of ultraviolet intensity, consequently conventional ultraviolet disinfector cavity must guarantee to keep the certain distance between fluorescent tube and the casing, it is serious apart from too big ultraviolet attenuation, apart from the undersize contact time shorten, all can not reach the disinfection effect of requirement, consequently conventional disinfector casing all need dispose according to fluorescent tube power, the casing volume is high or low.
The micro particles existing in the water medium for a long time and dissolved salts such as calcium, magnesium and the like can deposit and adhere on the surface of the quartz tube to form scale, the temperature can rise when the lamp tube is continuously used, and the calcium and the magnesium in the water can be accelerated to be separated out when the temperature rises. The scale on the surface of the quartz tube directly blocks the penetration of ultraviolet rays, so that the effective radiation quantity of the ultraviolet rays is directly influenced, therefore, the regular cleaning of the scale on the surface of the quartz tube is an important maintenance means for keeping the stable operation of the ultraviolet sterilizer, and a cleaning system must be configured for a large and medium-sized ultraviolet sterilization system to ensure the surface cleaning of a lamp group sleeve.
The mercury vapor lamp tube and the quartz tube of the conventional ultraviolet sterilizer are made of glass materials and are fragile, and the mercury components of the broken mercury vapor lamp tube directly pollute water. Uv disinfection is the ability of the equipment to achieve effective uv dose, i.e., the dose of uv light that can be used to inactivate microorganisms in uv disinfection equipment, usually in millijoules per square centimeter (mJ/cm2) or joules per square meter (J/m 2). According to the description of the ultraviolet disinfection equipment for urban water supply and drainage (GB/T19837-2005), the ultraviolet effective dose of the equipment is calculated according to the following formula.
(1)ED＝ND×CLH×CJG
In the formula:
ED-device UV effective dose, mJ/cm 2;
ND-average ultraviolet dose of equipment under the new ultraviolet lamp tube state, mJ/cm 2;
CLH-the ultraviolet lamp aging factor;
CJG-ultraviolet lamp sleeve structure factor.
The average dose of the uv rays of the apparatus in the above equation is calculated by the following equation.
(2)ND＝I×t
In the formula:
ND-mean dose of UV to device, mJ/cm 2;
i-ultraviolet intensity, mW/cm 2;
t-exposure time, s.
As can be seen from the above equations (1) and (2), the effective dose of ultraviolet rays can be ensured by adjusting the intensity of ultraviolet rays and the exposure time. Therefore, the original ultraviolet disinfection equipment needs to prolong the exposure time to achieve reasonable ultraviolet effective dose of the equipment due to the power limitation of the mercury vapor lamp tube, but the prolonged exposure time needs to have an overflowing cavity with enough volume, and the ultraviolet decays rapidly in water, so that the ultraviolet intensity of the equipment needs to be increased by large-flow disinfection equipment, namely the power and the number of the mercury vapor lamp tube are increased. The excessive lamp tubes cause the lamp tubes and the sleeves to be fragile, the temperature rise on the surfaces of the sleeves causes scaling to influence the penetration of ultraviolet rays, and the additional cleaning system is complicated.
The shell of the conventional ultraviolet sterilizer is mostly cylindrical, and the installation and fixation requirements are high. The inlet and outlet of the small ultraviolet sterilizer are mostly in threaded connection, and the main body is fixed by the fixing support and then installed. Most of the inlets and outlets of the medium-sized ultraviolet sterilizer are connected by flanges, and the requirement on the connection size of pipelines is high. The ultraviolet sterilizer is provided with a mercury vapor lamp tube and a quartz tube, belongs to fragile products and needs to be far away from a vibration source.
