Description

Technical Field

[0001] The present application relates to the technical field of heating equipment, and in particular to an auxiliary heating device for an air-temperature vaporizer. Background Art

[0002] LNG air-temperature vaporizers often suffer from low vaporizer efficiency due to frost, which affects the natural gas temperature at the vaporizer outlet and often requires the addition of some auxiliary heating measures. Among them, the more common auxiliary heating measures include forced ventilation, hot water bath, steam heating, and electric water bath heating. Conventional water bath and steam heating devices are mostly installed at the bottom of the vaporizer and welded with steel pipes. According to the vaporizer medium flow diagram, it can be seen that the area with relatively low vaporizer temperature is the vertical surface on the side of the vaporizer close to the air inlet, where the temperature difference is large and frost is more significant than other parts. The heating device designed at the bottom has relatively low heat exchange efficiency and large energy waste. Since the structure is welded, it is not conducive to maintenance. Utility Model Content

[0003] In order to solve or partially solve the problems existing in the related art, the present application provides an auxiliary heating device for an air-temperature vaporizer, which can be quickly disassembled and connected, and the heat energy can simultaneously take into account the low-temperature areas at the bottom and sides, thereby realizing the overall thermal efficiency utilization of the air-temperature vaporizer.

[0016] The technical solution provided by this application may have the following beneficial effects:

[0017] This device is connected to a vertical coil through a horizontal coil, and then, after being connected through two horizontal coils through a horizontal short pipe, and two vertical coils through a vertical short pipe, it finally forms an L-shaped pipe plate connected from one end to the other and supported by a support frame to stand upright. When in use, the entire device is inserted into the bottom of the air temperature vaporizer, and the heating medium enters the pipe through one end of the horizontal coil at one end, flows from the bottom of the horizontal coil to the vertical coil, passes through the top vertical short pipe, and flows downward to the second section of the vertical short pipe back to the horizontal coil, and the cycle repeats until the heating medium returns to the other end and leaves the coil.
