Tank cleaning equipment for offshore oil platform and tank cleaning method

Abstract

The invention discloses tank cleaning equipment for an offshore oil platform and a tank cleaning method. The tank cleaning equipment comprises a protective cover, motors oppositely arranged in the protective cover, and a lengthened push rod which is mounted between the motors, the upper part of the protective cover is sleeved with an anti-collision guardrail, the bottom of the protective cover isprovided with a first quick connector, the first quick connector serves as a liquid phase outlet, a partition plate for protecting the motors from being damaged by dirty oil sludge and a liquid inletopening are arranged at the upper part of the protective cover, the motors are arranged at the bottom of the protective cover and are connected with a second quick connector through an air supply pipeline, the second quick connector serves as a nitrogen inlet, the nitrogen inlet has enough gas circulation amount and is convenient to disassemble and assemble, a plurality of push rod height adjusting screw rods are installed on the top of the lengthened push rod and the upper part of the lengthened push rod, and a plurality of push rod connecting threads are further arranged on the lengthened push rod. According to the tank cleaning equipment for the offshore oil platform and the tank cleaning method, operators do not need to enter a tank body, the whole tank cleaning process is achieved, and through the tank cleaning equipment, suspension impurities in a tank can be removed, and the dirty oil sludge deposited at the bottom of the tank can further be removed, so that the efficiency of tank cleaning operation is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of offshore petroleum engineering, and particularly relates to tank cleaning equipment and a tank cleaning method for an offshore oil platform. Background technique [0002] At present, on the offshore oil production platform, the oil tank is usually cleaned by the operation of atmospheric pressure tank cleaning. Depending on the process treatment needs, tank cleaning needs to be carried out at least 4-10 times a year. [0003] The existing offshore oil production platforms often need to clean the storage tanks, most of which are closed and pressurized tanks. Inert and activate the tank body; when the explosion detector has no flammable gas and the oxygen concentration reaches the standard, the tank cleaning operation can be started. The process of cleaning a tank is as follows: [0004] (1) In the early stage of tank cleaning, a two-inch pipe was placed in the tank for suction and discharge; however, in ...
