A tank stripping system for chemical tankers to clean up cargo loading and unloading fluids

Abstract

The invention relates to a stripping system for cleaning cargo loading and unloading liquids of chemical tankers, which includes a compressed air delivery pipeline placed on a liquid infusion pipe and a residual liquid discharge pipeline. The position between the air delivery pipeline and the residual liquid discharge pipeline has an activated carbon crushing and feeding mechanism. The activated carbon crushing and discharging mechanism includes an activated carbon crushing component and a pipeline vibration buffer component. The activated carbon crushing component will crush the activated carbon powder from top to bottom. Incline the material into the infusion tube and discharge the loading and unloading liquid and activated carbon powder in the infusion tube into the residual liquid discharge pipeline along with the air compressed pump. The tubes vibrate together. The invention has the following advantages: ensuring the purging effect on the viscous loading and unloading liquid remaining on the inner wall of the infusion tube, and avoiding corrosion and deformation damage to the inner wall of the infusion tube.

Description

Technical field: [0001] The invention belongs to the field of chemical tankers, and in particular relates to a tank stripping system for cleaning cargo loading and unloading fluids of chemical tankers. Background technique: [0002] The chemical tanker stripping system is mainly to suction and sweep away the residual cargo oil in the cargo tank, cargo oil piping system or cargo pump, so as to reduce the residual volume as much as possible. In order to achieve an effective stripping effect, the chemical tankers currently on the market must Separately set up a special stripping system or use an air compression pump for stripping, but the stripping effect is not significant. [0003] Patent No. 201820809671.6 a chemical tanker stripping system and patent No. 201710132314.0 a chemical tanker stripping system and the use method of the system, both use compressed air or nitrogen to purge from the compressed air delivery pipeline to the infusion tube, but there are The following d...

[0002] The chemical tanker stripping system is mainly to suction and sweep away the residual cargo oil in the cargo tank, cargo oil piping system or cargo pump, so as to reduce the residual volume as much as possible. In order to achieve an effective stripping effect, the chemical tankers currently on the market must Separately set up a special stripping system or use an air compression pump for stripping, but the stripping effect is not significant

[0003] Patent No. 201820809671.6 a chemical tanker stripping system and patent No. 201710132314.0 a chemical tanker stripping system and the use method of the system, both use compressed air or nitrogen to purge from the compressed air delivery pipeline to the infusion tube, but there are The following defects: 1. For liquid chemicals with high viscosity, the liquid chemicals are easy to adhere to the inner wall of the infusion tube, and the purging effect is poor, and it is easy to block the next time the liquid chemicals are transported, affecting the liquid state. The normal delivery efficiency of chemicals; 2. If a certain amount of corrosive loading and unloading liquid residue adheres to the inner wall of the infusion tube for a long time, it will corrode the inner wall of the infusion tube and affect the service life of the infusion tube. The loading and unloading fluid is purged clean, so it will cause greater corrosion to the inner wall of the infusion tube, affect the service life of the infusion tube, and easily cause deformation and damage of the inner wall, and leakage of the loading and unloading fluid during transportation
