Sediment discharge system with sediment aggregation function

Abstract

The invention discloses a sediment discharge system with a sediment aggregation function. The sediment discharge system comprises a sedimentation tank, a base plate in the sedimentation tank is fixedly provided with multiple diversion piers, the multiple diversion piers are connected to the base plate in the sedimentation tank in sequence to be surrounded into multiple diversion rings, two adjacent diversion rings form a sediment aggregation area, each sediment aggregation area is internally provided with a sediment discharge branch pipe, and all the sediment discharge branch pipes are jointly connected to a sediment discharge main pipe; a center cylinder is arranged at the center position of the base plate in the sedimentation tank, a spray pipe communicated with the center cylinder is arranged above the center cylinder, the side face of the center cylinder is connected to and provided with a water supply pipe G1, the outside of the sedimentation tank is provided with a negative pressure sedimentation discharge pump and a centrifugal pump, the negative pressure sediment discharge pump is communicated with the sediment discharge main pipe, one end of the centrifugal pump is communicated with the water supply pipe G1, the other end of the centrifugal pump is connected to and provided with a water supply pipe G2, and the water supply pipe G2 is communicated with the sedimentation tank. The sediment discharge system with the sediment aggregation function can effectively discharge sediments, is simple in structure and worthy of promotion.

Description

technical field [0001] The invention belongs to the technical field of crude oil dehydration and sedimentation equipment for oil field surface systems, and relates to a mud discharge system with a mud accumulation function. Background technique [0002] During crude oil extraction and transportation, impurities such as sediment will enter. When crude oil enters the settling tank for dehydration, a large amount of sediment, flocs and other sediments will be deposited at the bottom of the settling tank to form sludge. The sludge must be regularly discharged from the settling tank to ensure settlement. The tank is functioning normally. [0003] Chinese utility model patent "Hydraulic rotary mud discharge device for settlement tank" (application number: 201120530679.7, publication date: 2012.08.15, announcement number: CN202376815U), discloses a hydraulic rotary mud discharge device for settlement tank, which uses hydraulic jet to automatically Rotate, but only rely on static p...

[0003] Chinese utility model patent "Hydraulic rotary mud discharge device for settlement tank" (application number: 201120530679.7, publication date: 2012.08.15, announcement number: CN202376815U), discloses a hydraulic rotary mud discharge device for settlement tank, which uses hydraulic jet to automatically Rotate, but only rely on static pressure to press the mud like a mud discharge pipe, and the mud discharge efficiency is low

[0004] Chinese utility model patent "Tank bottom mud discharger" (application number: 200720012410.3, publication date: 2008.03.26, announcement number: CN201040652), discloses a tank bottom mud discharger, which includes a tank body, a motor, a scraper and Bracket; the tank bottom sludge discharger is a device that uses a motor to drive the scraper head on the tank inner bracket to rotate and scrape the mud and then discharge the mud. It is easy to cause serious corrosion and scaling in the tank, and the moving equipment is easy to be damaged.

[0005] The Chinese invention patent "On-line sludge discharge device for crude oil storage tank" (application number: 201510699997.9, publication date: 2016.01.13, publication number: CN105233534A) discloses an online sludge discharge device for crude oil storage tank. The lower part of the storage tank includes a conical plate, a mud collecting chamber and a mud discharge pipe arranged in sequence from bottom to top. This device fixes the conical plate on the tank wall to guide the sediment, and then uses the slurry The pump sucks the mud away and cannot achieve complete mud discharge

[0006] To sum up, there is no mud discharge device with the function of sediment accumulation, which can effectively gather and discharge the sediment.
