Horizontal separator manual blowdown device and method

Abstract

The invention relates to a manual pollution discharge device and method for a horizontal separator. According to the technical scheme, the manual pollution discharge device comprises a main structure and pulley spool devices. The main structure is arranged inside the horizontal separator. The main structure comprises brushes, outer sand scraping plates, a main shaft and inner supporting plates. The brushes are arranged at the bottoms of the outer sand scraping plates. The curvature radii of the bottoms of the outer sand scraping plates (including the brushes) and the curvature radii of the bottoms of the inner supporting plates are matched with the inner wall of the separator in shape. One hand wheel at the end close to the pollution discharge device is rotated to reel off one rope, and the other hand wheel at the end far from the pollution discharge device is rotated to coiling the other rope. The pollution discharge device slowly moves from one end of the separator to the other end of the separator under the traction of the other rope. Sludge is pushed by the pollution discharge device to be gathered into one pollution discharge pipe and then is discharged out. The manual pollution discharge device has the beneficial effects that the sludge can be thoroughly cleaned up on the condition that the separator does not stop operating; the flow field of fluid in the separator cannot be affected in the pollution clean-up process, and the separation effect of the separator cannot be affected; the device is simple in structure, flexible to operate and easy to realize; the device only needs to be operated manually without additional power equipment.

Description

Technical field [0001] The invention relates to an accessory for a horizontal separator in an oil and gas gathering and transportation system, in particular to a manual sewage discharge device and method for a horizontal separator. Background technique [0002] At present, due to the solid impurities contained in the products of oil and gas wells, the solid impurities are easy to deposit on the bottom of the separator during oil-gas-water separation in the gathering and transportation process. However, the horizontal separator has always been difficult to discharge due to structural limitations. Although the bottom end of the horizontal separator is equipped with sewage holes, due to the "horizontal arc" structure limitation of the lower part of the horizontal separator, the sewage holes cannot achieve complete sewage discharge. [0003] At the present stage, the production site mostly adopts the method of periodic shutdown of equipment for cleaning to thoroughly clean up the poll...

AI Technical Summary

Problems solved by technology

This method has the following two disadvantages: one is that it requires external power equipment, which is uneconomical; the other is that the high-pressure water jet will disturb the internal flow field of the separator and affect the separation effect

Therefore, this device has not been popularized
