Abstract

The invention discloses an energy-saving type submerged combustion gasifier. The energy-saving type submerged combustion gasifier comprises an air blower, an air channel, a combustor, a combustion chamber, a flue gas distributor, a water tank, a heat exchange tube bundle, a weir flow box, an alkaline liquid tank, a chimney, a gas-liquid separator and a chimney regulating valve, wherein the flue gas distributor comprises collecting tubes and bubbling tubes; one end of each bubbling tube is connected with each collecting tube; the bubbling tubes are arranged under the heat exchange tube bundle; at least one row of injection holes are formed in the top of each bubbling tube; the weir flow box is supported by a bracket which is fixed at the bottom of the water tank; the heat exchange tube bundle is suspended and supported by a suspension support structure at the top of the weir flow box and is submerged in water bath liquid in the water tank; the gas-liquid separator is mounted in the chimney; a bypass is arranged at the lower part of the chimney and is respectively connected with the combustor and the flue gas distributor through a first branch and a second branch. The energy-saving type submerged combustion gasifier is excellent in heat exchange effect, high in heat efficiency, relatively compact in structure and small in occupied area, is capable of saving energy and cost, and is particularly applicable to LNG receiving stations with moderate and high gasification capacities.

Description

technical field [0001] The invention belongs to the technical field of liquefied natural gas gasification, and relates to an energy-saving submerged combustion gasifier, in particular to a submerged combustion gasifier for gasifying low-temperature liquids. The submerged combustion gasifier is often used in It is used as a liquefied natural gas gasification device in a large liquefied natural gas receiving station. Background technique [0002] With the continuous development of my country's industrialization level and energy conservation and emission reduction work, the demand and use of energy, especially clean energy, have become more and more prominent. As an energy source, natural gas has the dual advantages of high efficiency and cleanliness, and has been widely used at home and abroad in recent years. my country's National Energy Administration proposes to increase the proportion of natural gas in primary energy to 12% by 2020. It is estimated that by 2020, my count...
