BLOCK filter for sea water purification from suspended solids and oil to the oil rig

摘要

The proposed utility model relates to equipment oil drilling platforms, namely the post-treatment means of sea water used in oil extraction technology. This solution is aimed at improving water quality, improving performance and ensuring environmental safety. Summary of the utility model is that the filter unit is staffed node electrolytic chlorination of the seawater, which consists, e.g., of an electrochemical generator chlorine and metering pump, the discharge nozzle is connected to a supply manifold, and a node forced himpromyvki consisting, e.g., of reaktora- solvent heater and the circulating pump and adapted to alternately connecting it to the cavity of each filter. Himpromyvki assembly disposed in the space between the inlet and outlet manifolds. Moreover, each filter body an additional pipe to be alternatively connected to either its external compressed air system or a drainage system, wherein, the additional pipe arranged from the condition _H1H2, where:; ₁ H - distance from the nozzle to the tube walls;; H ₂ - distance from the tube walls to the first (uppermost) of the through hole in the tube of the filter element. drainage system is also provided with quick-valve.; It is also important that the filter elements are made of titanium alloys in the form of pipes of corrugated transversely to the longitudinal along the length of the crests and troughs, and through holes arranged in the depressions over which the wound wire partially tapered in diameter, and, on one of the the two planes formed by flattening periodically formed cross grooves (steps) depth of 0.05 ... 0.1 the diameter of the wire. The wire is wound on the tube tightly, turn to turn so that the windings touch each other by the flattening plane, and the transverse grooves form a filtering gap of fixed size. Thus the overall dimensions of the filter elements formed from the ratio: L / D≥15, where: L - length of the filter element from the tube walls to the free edge (not connected to the pipe wall) end; D - outside diameter of the wrap wire member.
