Embodiment

[0012] see figure 2 , The embodiment of the present invention includes a shell 1, a vaporization tube bundle 2, a circulation line 3, a steam inlet pipe 4, a steam-water mixer 6, a vaporization inlet pipe 7, and a vaporization outlet pipe 8.

[0013] The casing 1 is cylindrical, and a cavity 5 is formed inside it, constituting a container for holding medium heat medium-water.

[0014] The vaporizing tube bundle 2 is fixed in the cavity 5 . The vaporization tube bundle 2 includes compact spirally coiled heat exchange tubes, a liquid separator ring, a gas collection ring, an outer tube for diversion support, an inner tube for diversion support, a partition and a support. The heat exchange tube is spirally coiled and arranged on the inner cylinder of the diversion support, and the two ends of the heat exchange tube are respectively connected with the liquid separation ring pipe and the gas collection ring pipe. The outer cylinder of the diversion support is set on the peripher...

Abstract

The invention relates to a water bath vaporizer provided with a vapor-water mixer. The water bath vaporizer is mainly applied to the fields of petrochemical engineering, natural gas, and air separation, is used for vaporizing liquefied natural gas, liquid oxygen, liquid nitrogen and the like, and also can serve as a peak-shaving vaporizer for vaporizing liquefied natural gas to be applied to various levels of natural gas receiving stations, bunkering stations or peak-shaving stations of docks, cities and the like. A cavity is formed in a shell, and a vaporizing tube bundle is arranged in the cavity; a circulating pipeline is communicated with the cavity; and a vaporizing inlet pipe and a vaporizing outlet pipe are communicated with the vaporizing tube bundle. The water bath vaporizer is characterized by also comprising the vapor-water mixer, wherein the vapor-water mixer is communicated with a vapor inlet pipe, the cavity and the circulating pipeline respectively; and the vapor-water mixer is fixed on the middle lower part of the shell. The water bath vaporizer is reasonable in structural design and can avoid water-hammer phenomena.

Description

technical field [0001] The invention relates to a water-bath vaporizer provided with a steam-water mixer, which is mainly used in petrochemical, natural gas, and air separation fields for vaporizing liquid natural gas, liquid oxygen or liquid nitrogen, etc., and can also be used for peak regulation of liquid natural gas vaporization Vaporizers are used in natural gas receiving stations, storage and transportation stations or peak-shaving stations at various levels such as docks and cities. Background technique [0002] At present, many of the vaporizers used for vaporizing liquefied natural gas, liquid oxygen or liquid nitrogen for peak regulation are water-bath vaporizers heated by steam. In a common water-bath vaporizer, the component that discharges steam into hot water uses an exhaust pipe 1', and a certain number of exhaust holes 2' are opened in the exhaust pipe. For details, see figure 1 . Its disadvantages are: the vaporization output greatly deviates from the rat...
