Description

technical field [0001] The invention relates to the field of ultraviolet fluid disinfection, in particular to an ultraviolet fluid processor. Background technique [0002] The main chamber of the reactor of the traditional closed ultraviolet processor is usually a single-layer cylinder, which is provided with a fluid inlet and outlet on the wall of the cylinder, and the end of the cylinder is equipped with an ultraviolet lamp and its sleeve, and the fluid flows automatically The water inlet flows into the cavity perpendicular to the direction of the ultraviolet lamp, and after being irradiated by ultraviolet rays, it flows out of the water outlet perpendicular to the direction of the ultraviolet lamp. The irradiation effect is greatly affected by the fluid mixing dynamics of the medium. The influence of mixing dynamics is increased, the ultraviolet radiation dose received by the fluid in the processor cavity is uneven, and the disinfection effect is unstable; in addition, be...

Problems solved by technology

[0005] But after a period of use, the applicant found that the reactor in the patent still had problems

In a reactor in which the outer cylinder is the circumscribed circle of the inner cylinder or separated by a partition (and the two adjacent partitions have a distance from the outer cylinder), although the cavity formed between the inner and outer cavities is relieved to a certain extent However, the cavity formed between the inner and outer cavity is not continuous but divided into several small cavities, and each small cavity has an uneven pressure on each position of the inner and outer cavity walls. In particular, the connection points of the inner and outer cavity walls are under the greatest pressure, so cracks or weld leakage problems are likely to occur during use; at the same time, due to the uneven ultraviolet radiation in each small cavity, there may be high local pollution concentrations. When the cavity When the water body in the interlayer is brought out of the cavity by the impact of the water entering the reactor and enters the inner cylinder, due to the different pollution concentrations in each cavity, the water brought out by each cavity will cause water flow in the inner cylinder. The different degrees of pollution lead to poor uniformity of the disinfection effect of the system, which further affects the overall disinfection effect; in addition, in the field of water treatment and disinfection, the low-voltage high-intensity ultraviolet lamp with a length of 1554mm has been widely used due to its suitable power intensity and good supply guarantee. Therefore, a low-pressure high-intensity ultraviolet lamp with a length of 1554mm is generally used in the manufacture of ultraviolet fluid processors, so that the size of the outer cavity is fixed. Similarly, in this patent, the inner cylinder is a round inscribed square cylinder, and its size It is also limited that when dealing with small-flow fluid disinfection, due to the small amount of fluid water, the arrangement of ultraviolet lamps is small, and the effective irradiation process of the fluid is short, the irradiation dose is reduced, and in the case of using the same lamp tube, the lamp array is less , the fluid has already flowed out of the inner cylinder without being well mixed, the fluid dynamic effect is weakened, and the probability of irradiation received by the fluid is also significantly reduced, so that the disinfection effect of the system on small flow fluid is poor
