Abstract

The invention discloses a water bath type liquefied natural gas carburetor which has convenient installation and good effect of continuously supplying air to the engine. The carburetor includes a water bath type cylinder body which is internally provided with a heat exchange cavity, wherein, the water bath type cylinder body is provided with a water inlet and a water outlet, which are communicated with the heat exchange cavity. The heat exchange cavity is internally provided with two spiral heat exchange tubes which are entwisted together. Both ends of each heat exchange tube are respectively communicated with a liquefied natural gas inlet and a natural gas outlet, and the liquefied natural gas inlet and the natural gas outlet are respectively arranged on both ends of the water bath type cylinder body. The invention is used for gasifying the liquefied natural gas to normal natural gas and supplying gas for the engine.

Description

Technical field [0001] The invention relates to a vaporizer for water-bath type liquefied natural gas. Background technique [0002] At present, countries around the world are actively exploring the use of natural gas as vehicle fuel to reduce the pollution of vehicle exhaust to the atmosphere and protect the earth's ecological environment. There are roughly two ways to use natural gas as vehicle fuel: The first way is to store the compressed natural gas in a gas cylinder, and then use the compressed natural gas in the gas cylinder as a gas source, and supply it directly after being decompressed by a pressure reducing device. For the engine, this method is relatively simple and easy to implement, but the air storage per unit volume is small, which makes a single stroke shorter and can only be used for short-distance driving; moreover, due to the high pressure in the cylinder, It brings safety hazards to the transportation and use of gas cylinders; another way is to store LNG in t...
