A tank cleaning system and cleaning method

Abstract

The invention relates to a tank cleaning system and a cleaning method, and relates to the technical field of tank cleaning devices and methods. The tank cleaning system comprises a to-be-cleaned tank,a filtering device, a buffer tank, a first solid-liquid separating device and a first liquid storage tank which are arranged in sequence, the filtering device is used for filtering cleaning waste liquid discharged from the to-be-cleaned tank, the buffer tank is used for storing cleaning waste liquid filtered by the filtering device, the first solid-liquid separating device is used for conductingsolid-liquid separation on cleaning waste liquid discharged from the buffer tank, the first liquid storage tank is used for collecting the cleaning waste liquid discharged from the first solid-liquidseparating device and obtained after the solid-liquid separation, a liquid outlet of the first liquid storage tank is connected to a cleaning liquid delivery pipe, and the cleaning liquid delivery pipe is used for conveying cleaning liquid into the to-be-cleaned tank. According to the tank cleaning system in the embodiment, the cleaning waste liquid obtained after cleaning can be recycled, the cleaning liquid can be saved, and environmental pollution can be avoided; and automatic control is conveniently achieved, and the cleaning operation efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of tank cleaning devices and methods, in particular to a tank cleaning system and cleaning method. Background technique [0002] Mud is the "blood" of drilling engineering. During long-term use, mud will settle in the mud tank, which will affect the effective volume of the mud tank. If it is not cleaned in time, it will affect the use of the tank, and cross-contamination of mud may occur etc. Therefore, the tank needs to be cleaned regularly. [0003] Due to the small size of the mud tank on the drilling platform and the limited space on the drilling platform, it is difficult for general cleaning equipment to carry out cleaning operations. At present, the conventional cleaning is mostly carried out manually into the tank body, and manual cleaning is still the main method. Serious safety and environmental hazards: 1. The manual cleaning method often uses personnel to enter the tank for cleaning. Th...

[0002] Mud is the "blood" of drilling engineering. During long-term use, mud will settle in the mud tank, which will affect the effective volume of the mud tank. If it is not cleaned in time, it will affect the use of the tank, and cross-contamination of mud may also occur etc., so the tank needs to be cleaned regularly

[0003] Due to the small size of the mud tank on the drilling platform and the limited space on the drilling platform, it is difficult for general cleaning equipment to carry out cleaning operations. At present, the conventional cleaning is mostly carried out manually into the tank body, and manual cleaning is still the main method. Serious potential safety and environmental hazards: 1. The manual cleaning method often uses personnel to enter the tank for cleaning. The operating space in the tank is narrow, it is in a semi-closed state, and the oxygen content is low. For a long time, there have been safety accidents caused by personnel entering the tank for cleaning occur, seriously affecting the safety of mud services

2. The manual cleaning method often piles up the sludge in the open air, which will cause soil and water pollution, and environmental disputes caused by it happen from time to time
