Unloading device

Abstract

The invention provides an unloading device that comprises a manifold assembly and a frame assembly, the manifold assembly is communicated with an LNG tank car and an LNG storage tank while unloading liquid from the LNG tank car to transport LNG, the manifold assembly is arranged on the frame assembly used for supporting the manifold assembly, the unloading device also comprises an unloading flangefixing and sealing device provided with the fixing and sealing function of an unloading hose flange upon completion of unloading, the unloading flange fixing and sealing device is arranged on the frame assembly, the unloading device has fixing and sealing effect on the unloading hose flange through the unloading flange fixing and sealing device thereof and avoids daily frequent clearing of the unloading flange, and the unloading device is integrated with instrument display, risk detection and warning, and electrical automated control and has a simple unloading operation, the entire unloadingprocess is controlled by one device.

Description

technical field [0001] The invention relates to the field of liquefied natural gas filling, in particular to a vehicle unloading device. Background technique [0002] In recent years, my country's LNG industry has achieved rapid development. LNG has become a clean energy alternative to diesel in addition to meeting the traditional civil and industrial gas and gas-fired power generation needs. LNG and CNG refueling stations are the main supply methods of natural gas for vehicles. At present, there are LNG skid-mounted refueling stations, CNG hydraulic sub-stations and LNG / L-CNG refueling stations in China. [0003] The LNG unloading process is the operation of transferring the LNG in the container or tanker to the LNG storage tank. The current unloading method of the LNG filling station adopts the method of separate cooperation between the unloading platform and the unloading operation column, which greatly increases the unloading process. The operation is complicated and un...

[0003] The LNG unloading process is the operation of transferring the LNG in the container or tanker to the LNG storage tank. The current unloading method of the LNG filling station adopts the method of separate cooperation between the unloading platform and the unloading operation column, which greatly increases the unloading process. The operation is complex and uncontrollable, and there is no specific fixing and sealing device for the unloading hose and its flange. Foreign matter is easy to enter the pipeline during the non-unloading period, resulting in frequent cleaning of the unloading flange in daily life.
