Abstract

The invention discloses an energy-saving submerged combustion type gasifier, comprising a blower, an air duct, a burner, a combustion chamber, a flue gas distributor, a water tank, a heat exchange tube bundle, a weir flow box, a lye tank, a chimney and a gas Liquid separator and chimney regulating valve; the flue gas distributor includes a collecting pipe and a bubbling pipe, one end of the bubbling pipe is connected with the collecting pipe, the bubbling pipe is located under the heat exchange tube bundle, and at least one row of jets is arranged on the top of each bubbling pipe Holes; the weir box is supported by a bracket fixed at the bottom of the water tank, and the heat exchange tube bundle is suspended and supported by the hanging support structure on the top of the weir box, and is immersed in the water bath in the water tank; a gas-liquid separator is installed inside the chimney; the chimney The lower part is provided with a bypass, the bypass is connected with the burner through the first branch, and the bypass is connected with the flue gas distributor through the second branch. The invention has good heat exchange effect and high thermal efficiency, makes the gasification device more compact in structure, small in floor space, saves energy and cost, and is especially suitable for the LNG receiving station with the amount of gasification in processing.

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...
