Description

Offshore production platform plain type prevents returning liquid floor drain device

Technical Field

The utility model belongs to the field of platform floor drains, and particularly relates to a simple liquid return prevention floor drain device for an offshore production platform.

Background

Due to the requirements of flow and safety and environmental protection, a large number of floor drains need to be arranged on a deck of the offshore oil and gas production platform. The main functions are as follows: the rainwater in rainy seasons can be conveniently treated in a centralized and unified manner and enters the drainage system through the floor drain; the production flow needs water quality observation, equipment cleaning and the like; the production requirement of safety and environmental protection is ensured, equipment leakage and the like can enter the drainage system through the floor drain, and direct oil spill is prevented from entering the sea; a common floor drain of an offshore production platform is of a sinking type, and a basket type mesh-shaped filter screen is installed for preventing mechanical impurities from entering a flow.

When the existing filter screen is used, if a manifold is blocked, the floor drain is discharged downwards to cause floor drain return liquid on the same deck, meanwhile, as a working deck is positioned at the lowest layer of a marine production platform, the floor drain liquid uniformly enters an open type open drainage groove, the drainage groove is directly and reversely flushed into the floor drain through the manifold when the liquid level of the open drainage groove is high, the working deck overflows from the deck, if oil pollution is discharged, the oil pollution diffusion area is directly increased, even the environmental protection problems of environmental pollution and the like exist, and great potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

The utility model provides a marine production platform plain type prevents returning liquid floor drain device, be used for solving current filter screen when using if the manifold takes place under the condition of jam, can cause the same floor deck floor drain to return liquid through the floor drain downward discharge, the working deck is owing to be in marine production platform's lower floor simultaneously, floor drain liquid is unified to get into uncovered formula division gutter, division gutter liquid level is higher then directly backward to gush the floor drain once more through the manifold, overflow the deck, if the greasy dirt of discharging, then can directly cause greasy dirt diffusion area increase, even there is environmental protection problems such as polluted environment, there is the technical problem of very big potential safety hazard.

In order to solve the technical problem, the simple liquid return prevention floor drain device for the offshore production platform comprises a drain box, wherein a collecting groove is formed in the drain box, a floor drain grid is detachably mounted above the drain box, a mounting hole is formed in the lower portion of the drain box, a drain pipe is sleeved in the mounting hole, a filter cylinder is arranged in the drain pipe, a drain cylinder is detachably mounted above the filter cylinder, the upper portion of the drain cylinder is connected with the mounting hole in a clamping mode, a plug is arranged below the inner wall of the filter cylinder, and a sealing gasket is fixedly arranged in the middle of the plug.

Preferably, the blowdown cylinder is in a hollow round table shape, and the larger end of the blowdown cylinder is opened upwards.

Preferably, the end cap is the circular cone arrow point form, just the maximum diameter of end cap is greater than the bottom surface internal diameter of a blowdown section of thick bamboo, the external diameter of sealed pad equals the internal diameter of blowdown section of thick bamboo bottom surface.

Preferably, the filter cylinder is cylindrical, and a plurality of filter holes are formed in the annular surface and the bottom surface of the filter cylinder.

Compared with the prior art, the utility model has the following advantages:

according to the simple liquid return prevention floor drain device for the offshore production platform, sewage firstly passes through the sewage discharge groove, and passes through the floor drain grating on the sewage discharge groove, large garbage is filtered by the floor drain grating, then the sewage enters the collecting groove, enters the sewage discharge barrel through the collecting groove, then is discharged through the filtering holes in the filter barrel, and is discharged through the sewage discharge pipe.

Detailed Description

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a marine production platform plain type prevents returning liquid floor drain device, includes blow off case 1, sets up collecting vat 3 in the blow off case 1, but 1 top demountable installation floor drain grid 2 of blow off case, and mounting hole 6 is seted up to blow off case 1 below, and blow off pipe 5 is established to the cover in the mounting hole 6, is equipped with in the blow off pipe 5 and strains a section of thick bamboo 7, strains a detachable installation blowdown section of thick bamboo 4 in 7 tops of section of thick bamboo, and 4 tops of blowdown section of thick bamboo and 6 joints of mounting hole are strained the inboard and are equipped with end cap 9, and end cap 9 middle part rigidity is equipped with sealed pad 8.

Further, the sewage discharging cylinder 4 is in a hollow round table shape, and the larger end of the sewage discharging cylinder 4 is opened upwards.

Further, the plug 9 is in a conical arrow shape, the maximum diameter of the plug 9 is larger than the inner diameter of the bottom surface of the pollution discharge cylinder 4, and the outer diameter of the sealing gasket 8 is equal to the inner diameter of the bottom surface of the pollution discharge cylinder 4.

Further, the filter cartridge 7 is cylindrical, and a plurality of filter holes are formed in the annular surface and the bottom surface of the filter cartridge 7.
