Abstract: The present invention provides a spiral cylinder-shaped discharge unit for an ozone generator, wherein the discharge unit comprises at least one ground electrode, at least one insulating layer and at least one high voltage electrode that are stacked together and integrally curled into a number of spiral cylinder-shaped coils, wherein the high voltage electrode and the ground electrode are separated by the insulating layer, and gaps are respectively present between the ground electrode and the insulating layer, and between the insulating layer and the high voltage electrode. The discharge unit is applicable to various kinds of ozone generator and can significantly improve ozone productivity of a single discharge unit and reduce manufacture cost.

Abstract: A UV sterilizer with a double-chamber structure comprises an inner tube and an outer tube with different size, the inner tube being partly surrounded by the outer tube thereby forming an inner chamber and an outer chamber, the inner chamber is the space encircled by the inner tube and the outer chamber is the annular space encircled by the overlapped portions of the inner tube and the outer tube; a first end portion of the inner tube is located outside the outer chamber and provided with a first water port, a second end portion of the inner tube is located inside the outer chamber and provided with a second water port communicating with the outer chamber; a first end portion of the outer tube is sealingly connected with the outer wall of the inner tube, while a second end portion of the outer tube is sealed; sleeved UV lamps are arranged in the outer chamber or in both the inner chamber and the outer chamber.

Abstract: The invention provides a fluid UV sterilization system capable of automatically and stably keeping the fluid level, which includes a channel, a UV lamp module group, an electrical controller and a mounting bracket for UV lamp module(s), each UV lamp module comprising a frame and a plurality of UV lamps, the orientation of the frame and the lamps is perpendicular to or forms an angle with the general flow direction in the channel. A baffle is provided on either or both of the upstream and downstream of at least one of the UV lamp module(s), and the bottom of the baffle extends to such an extent towards the bottom of the channel that it at least reaches within the effective radiation distance of the UV lamp module group towards the fluid surface. The fluid UV sterilization system according to the present invention can control the fluid level automatically and stably, and can be used for the sterilization of domestic sewage, industrial sewage, recycled water, tap water and other kinds of water.

Abstract: A UV sterilization system with autocleaning structure comprises scrubbing collars, at least one cleaning liquid box and at least one sliding bar. Said cleaning means further comprises at least one towing bar, at least one sliding bar and at least one supporting bar. The boxes are vertically mounted on or fixed to the supporting bar(s) to form together with the supporting bar(s) a rectangular shape. A cleaning liquid addition port and a cleaning liquid drain port are respectively provided at the top and close to the bottom of each cleaning liquid box. Said cleaning liquid addition port is connected with a cleaning liquid supply pipe and the cleaning liquid drain port is closed by a detachable sealing member. Several sets of holes with the same diameter for scrubbing collars are provided on the opposite sides of each box with each set at the same height. Each UV lamp is separately installed within a protective sleeve passing through the scrubbing collars.

Abstract: This Invention relates to a ultraviolet water sterilization device having a sterilization chamber module into a modularized configuration each module having two water-through ports, one port is used as a water inlet and the other port as an outlet of the sterilization chamber. The sterilization chamber may be formed into a single-wall configuration or a casing configuration. Inside the sterilization chamber are distributed n≧1 ultraviolet lamps with glass sleeves. Each chamber module may be used individually or in combination of two, three or more modules in a large chamber to meet the need of sterilization for a large water volume. Each module can be also arranged in separate sections so as to lessen manufacturing difficulties and simplify the assembly process.
