Background

The open type drainage system plays an important role on an offshore oil and gas production platform, and mainly collects rainwater, sewage, dirty oil and liquid leaked by equipment or a skid block, wherein the rainwater is open in the atmosphere, and the floor drain is an inlet of the open type drainage system. On an offshore production platform, due to the fact that the offshore weather conditions are severe, the drainage floor drain is usually blocked by a drainage system due to the fact that corrosion rust slag, oil sludge, gravel, sundries and the like enter a pipeline, accumulated water and oil sludge on a deck are discharged everywhere, the deck is wet and smooth, and people can slide to the deck easily. In addition, the chemical oil stains contain harmful substances such as benzene and mercury, the harmful substances overflow to a deck and cannot be collected to an exhaust system along with a floor drain for treatment, and the harmful substances are brought into living and office places after being contacted by shoes, clothes and the like of workers, so that the health of the workers is influenced.

However, the floor drain plug of the offshore oil and gas production platform often has more hard impurities such as rust slag, gravel and the like along with oil sludge, and unlike household fruit peels, vegetables, paper scraps and the like, the plug is easy to smash, so that sometimes power shortage occurs, and plugging can not be realized.

2. The method for cleaning sewage by cutting and disassembling is used, but a trap of an offshore platform drainage system is mostly positioned on the reverse side of a deck, the distance from the next deck is higher, a very high scaffold needs to be taken for sewage discharge from a cleaning port, the workload is high, and a plug at the trap can not be disassembled due to corrosion. If the cutting is dismantled and is decontaminated, take a lot of work and time, the initial just of some trap designs in addition does not have the blowdown and clears away the mouth. In addition, if the pipe at the downstream of the trap is clogged with the foreign matter, the foreign matter cannot be cleaned through the dirt cleaning port.
