Modular structure of open-frame gasifier system

Abstract

The invention provides a modular structure of an open-frame gasifier system. The modular structure is provided with a heat exchange plate module and a seawater pipeline adjustment platform module; theheat exchange plate module is provided with a steel structure frame body; the interior of the steel structure frame body is divided into a plurality of heat exchange spaces by a steel structure retaining wall; the bottom end of each heat exchange space is provided with an LNG tube bundle connected with an LNG main tube, and the top end is provided with an NG tube bundle connected with an NG maintube; the LNG tube bundles are connected with the NG tube bundles through heat exchange tube bundles or heat exchange tube plates; each heat exchange space is provided with a water tank correspondingto each heat exchange tube bundle or heat exchange tube plate; the seawater pipeline adjustment platform module is arranged on one side of the heat exchange plate module, and includes a seawater mainpipe and seawater branch pipes respectively connected with the seawater main pipe; each seawater branch pipe is provided with a regulating valve; and the seawater branch pipes are connected with the water tanks in the heat exchange spaces.

Description

technical field [0001] The present invention relates to an open rack vaporizer (ORV) system for use in an LNG receiving terminal. Background technique [0002] In an LNG receiving station, an open rack vaporizer (ORV) system is generally configured in the gasification unit. [0003] The existing open rack vaporizer (ORV) system mainly includes: [0004] 1. Tube bundle plate (mainly including LNG header, LNG header at the bottom, heat exchange panel (heat exchange tube bundle), NG header at the top, NG header, transition joint) [0005] 2. Seawater distribution system (mainly including seawater headers, seawater distribution pipelines, seawater distribution valves, single and bilateral tanks) [0006] 3. Steel structure (including top frame, internal maintenance platform, windproof board). [0007] These systems are relatively complicated, and the manufacturers supply parts for spare parts, with thousands of parts and tens of thousands of bolts. The amount of construction ...

AI Technical Summary

Problems solved by technology

[0010] 1. The huge amount of construction and the long installation period seriously affect the progress of the on-site project;

[0011] 2. There are many spare parts, and it is easy to miss or lose parts on site;

[0012] 3. It is difficult for manufacturers to coordinate, and the cost of service labor is relatively high;

[0013] 4. The installation is complicated, and the requirements for installation instructors and on-site construction personnel are relatively high;

[0014] 5. The construction precision of the concrete water tank is relatively high;

[0015] 6. The functional systems are unclear and the interface is blurred
