Seawater distributor for open frame type gasifier

Abstract

The invention discloses a seawater distributor for an open frame type gasifier, and relates to the field of open frame type gasifiers. The seawater distributor comprises a seawater tank, wherein the inside of the seawater tank is divided into a buffer region, a distribution region and an overflow region by partitions; a buffer device is arranged in the buffer region; the buffer device comprises a buffer seat, multiple buffer plates and a buffer cover; all the buffer plates are fixed on a screw rod through nuts; the buffer seat is of a barrel-shaped structure, and the lower end of the buffer seat is fixed at a seawater inlet formed in the bottom of the seawater tank; the multiple buffer plates are arranged above the buffer seat from bottom to top in a spacing manner; the buffer cover is located above the uppermost buffer plate; seawater passing holes in all the buffer plates are coaxially arranged, and the diameters of the holes are gradually decreased from bottom to top; the buffer cover is formed by connecting one trapezoid folded plate with two straight plates; and the two straight plates are horizontally connected to two bent ends of the trapezoid folded plate respectively. The distance between every two adjacent buffer plates can be adjusted, so that the seawater distributor can adapt to fluctuation changes of a seawater flowrate to guarantee the stability of seawater flowing; and the buffer device is convenient to install and maintain.

Description

technical field [0001] The invention relates to the technical field of open-frame gasifiers, in particular to a seawater distributor for open-frame gasifiers. Background technique [0002] As a clean energy source, natural gas is getting more and more attention, and liquefied natural gas (LNG) grows rapidly every year, becoming one of the fastest growing energy industries in the world. As my country's demand for energy continues to grow, LNG plays an important role in optimizing my country's energy structure, effectively solving ecological and environmental protection problems, and achieving sustainable economic and social development. Natural gas is often stored and transported in liquid form, and before being transported to the end use, LNG needs to be vaporized to normal temperature gas with a gasifier. [0003] Open Rack Vaporizer (ORV, Open Rack Vaporizer) is a vaporizer with seawater as the heat source. The basic unit of the vaporizer is a heat exchange tube, which is...

AI Technical Summary

Problems solved by technology

The seawater distributor for gasifier disclosed in the above patents has the following problems: 1. The structure of the rectangular bending buffer cover adopted by the distributor is complicated, it is difficult to manufacture and install, and it is easy to be damaged during use, and because the buffer cover is a whole The structure makes maintenance more difficult; 2. During installation and use, the buffer cover cannot adjust the spacing according to the change of seawater flow. When the seawater flow fluctuates significantly, it will affect the uniformity and stability of the liquid film.
