Chemical tanker deck residual liquid system

Abstract

A disclosed chemical tanker deck residual liquid system comprises a deck, a liquid drainage pipeline, a residual liquid cabin and a rain well cabin, the liquid drainage pipeline is obliquely arranged from high to low in the direction from the rain well cabin to the residual liquid cabin, a deck valve is arranged in the rain well cabin, one end of the liquid drainage pipeline is connected with a valve port of the deck valve, the other end of the liquid drainage pipeline extends into the residual liquid cabin, and a water storage elbow structure is formed in the residual liquid cabin. According to the technical scheme, compared with a previous system in the prior art, a pneumatic diaphragm pump is not needed, the initial cost and the production cost are reduced, the operation cost is low, the later maintenance cost of the pneumatic diaphragm pump is saved, and the trouble that part of pneumatic diaphragm pumps are insufficient in self-suction capacity is also solved.

Description

technical field [0001] The invention relates to the field of oil tanker equipment, in particular to a deck residual liquid system of a chemical tanker. Background technique [0002] When the deck residual fluid of an oiled ship remains in the rainwater well for a long time, the toxic or harmful substances contained in the residual fluid itself may cause harm to the ship and the crew, and the residual fluid may also produce some harmful volatile gases. Ships usually use fixed screw pumps, centrifugal pumps or pneumatic diaphragm pumps to transfer the deck residual liquid in the rainwater well. Once the transfer pump fails, the deck residual liquid will remain in the rainwater well for a long time, causing a greater safety hazard. Contents of the invention [0003] (1) Solved technical problems [0004] The purpose of the present invention is to provide a chemical oil tanker deck residual liquid system in order to solve the above problems, and to overcome the defects of the...
