Description

Multi-channel overcurrent type sterilizing device

Technical Field

The utility model relates to the field of water treatment, in particular to a multichannel overcurrent type sterilizing device for water treatment equipment.

Background

The working principle of the multichannel overcurrent type sterilizing device is as follows: the water flow is made to flow through the ultraviolet lamp irradiation pipe, and 253.7NM ultraviolet ray penetrating pipe passes through the water for sterilization and disinfection. The multichannel overcurrent type sterilizing device is characterized by comprising: the water body flows at a certain speed, and the flowing time of the water flow is not more than 1S, so that the sterilization and disinfection can be fast performed. However, it is necessary to irradiate the water flow with ultraviolet rays as much as possible in order to achieve satisfactory sterilization and disinfection effects. In order to achieve sterilization and disinfection, the following two solutions are generally adopted:

1. the ultraviolet lamp with high intensity is adopted, and the surface required intensity of the ultraviolet lamp is required to exceed 30000UW/CM2 according to the water quality standard. To generate the ultraviolet intensity, a high-power ultraviolet sterilizing lamp needs to be selected, and the high-power ultraviolet lamp has larger volume and higher energy consumption, thus being not beneficial to popularization and application.

2. The ultraviolet irradiation time of the water flow is prolonged, so that the disinfection effect is improved, a longer sterilizing lamp tube is used in the prior art, a longer ultraviolet irradiation pipeline is made, or a vortex rotating structure is formed on the wall of the water flow pipeline to prolong the water flow path, and further the water flow time is prolonged. However, in the case where the internal space of the water treatment apparatus is limited, it is impossible to provide a long ultraviolet lamp and a pipe. That is, the prior art either requires a large space for accommodating the ultraviolet lamp and the pipeline, which is not beneficial to miniaturization of the product, or is complicated in manufacturing process and high in production cost.

Chinese patent CN202221470194.8 discloses a structure of an ultraviolet-resistant plastic housing multi-channel overcurrent sterilizing device, which can sterilize the passing water; meanwhile, the glass tube can be cleaned on the premise of not disassembling the structure of the sterilizing lamp, but the technical problem that the water flowing time is prolonged in a limited space cannot be solved.

Chinese patent CN202220523511.1 is a multi-channel overcurrent type sterilizing device, which can clean glass tube without disassembling the structure of the sterilizing lamp; but it cannot solve the technical problem of prolonging the water flow time in a limited space.
