Liquefied gas ship combined gas test device

Abstract

The invention discloses a liquefied gas ship combined gas test device, and belongs to the technical field of liquefied gas ships. The device comprises an unloading device which connects a transport vehicle with a ship, and a feeding control device; the unloading device comprises an unloading liquid pipe, an unloading gas pipe and an unloading gasifier; the feeding control device comprises a liquid feeding pipe and a gas feeding pipe; and a multifunctional state conversion device is arranged between the liquid feeding pipe and the gas feeding pipe, converts liquid in the liquid feeding pipe into gas at different temperatures, and is connected with the ship through the gas feeding pipe. By combining the unloading device, the feeding control device and a return gas treatment device, the combined special gas test device integrating unloading, gasification, heating, temperature control, pressure control, flow control and return gas treatment is formed, the combined device is integrally arranged in a modularized mode and used in a combined mode according to different ship use requirements, and the whole device is convenient to transport, and assemble for use, and is good in convenience property and high in flexibility.

Description

technical field [0001] The invention belongs to the technical field of liquefied gas ships, and in particular relates to a gas test combination device for liquefied gas ships. Background technique [0002] Due to the continuous improvement of environmental protection requirements, the number of ships using liquefied gas such as LNG or LPG as the main power fuel is gradually increasing, and the number of ships transporting such liquefied gas is also increasing. It is necessary to carry out the utility test of its fuel tank or transport tank, and it is necessary to pass liquids and gases of different states and temperatures into the tank for gas test tests. However, there is no special equipment matching these gas test tests in China or even in the world, which leads to the test The process is cumbersome, time-consuming and not environmentally friendly. Contents of the invention [0003] Technical problem: Aiming at the above-mentioned problems in the prior art, the technic...
