Embodiment Construction

[0027] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0028] With reference to the accompanying drawings, the present invention relates to a UV water treatment system 10 comprising a reactor 12, an inlet line 14 and an outlet line 16 for supplying water through the reactor, a plurality of UV treatment lamps L-1, L-2 and L-3, the cover 18 at the opposite end of each UV lamp, the explosion-proof enclosure 20 at each end of the reactor, and the control and operating components 22 ( Figure 12 ).

[0029] The reactor comprises a main cylindrical shell 12a, preferably made of titanium, with a diameter ranging from 300mm to 600mm (depending on the desired flow capacity of the device). An annular flange 12b is welded to the end of the main body shell. The total length of the reactor from flange to flange is 1500mm.

[0030] An inlet pipe 14 is welded at 90° at the periphery to the surface of the lower part of the shell, the size of the inlet pipe 14 corresponds to the flow rat...

Abstract

An apparatus for employing ultraviolet treatment of ballast water in explosive atmosphere of the pump room of oil tankers, and for treatment of replacement water in explosive atmosphere of off-shore oil and gas platforms.

Description

field of invention [0001] The present invention relates to UV systems for ballast water treatment installed on ships and offshore platforms, in pump rooms with explosive gas atmospheres. Background of the invention [0002] UV systems have long been used in water treatment, including treatment of ballast water, to achieve biocidal and bactericidal effects. The UV system requires high power and voltage, which prevents the system from being installed in explosive gas atmospheres in tanker pump rooms and on offshore oil / gas platforms. Such UV systems for tankers and platforms are built into large vessels that are difficult to fit in confined spaces on board ships and platforms. The main purpose of the present invention is to solve the problem of installing a high power and voltage UV ballast water treatment system on a tanker with a pump room in an explosive gas environment or on an offshore oil / gas platform. [0003] The present invention also provides a UV reactor with a wa...
