Terminal boil-off gas demisting device based on LNG gasifier

Abstract

The invention discloses a terminal boil-off gas demisting device based on an LNG (liquefied natural gas) gasifier. Generation of cold mist during LNG gasification can be effectively monitored in a fence range, the cold mist can be removed in time, different from a traditional treatment manner, the device can stop running when an LNG peak regulating station has no gasification task, and a physicalmethod is adopted for treating the cold mist, so that the energy consumption is further reduced. A whole system is simple in structure and low in investment, and the economic problem of station yard investment can be solved while the cold mist problem is solved. By means of a condensation treatment and collection assembly, condensation treatment of mist in airflow can be well achieved, the collection capacity of condensate water is effectively guaranteed, the demisting effect is improved, and the problems that the humidity of the environment around the gasifier is too high and the like are solved.

Description

technical field [0001] Specifically, the invention relates to a terminal evaporated gas demisting device based on an LNG gasifier, and relates to the field of demisting equipment for an LNG gasifier. Background technique [0002] With the increasing shortage of global energy, the energy structure is gradually changing, and the proportion of natural gas consumption is increasing year by year. Many LNG peak-shaving stations are built in China to solve the problem of energy peak-shaving. The general structure of the station is relatively simple, and the construction of relatively cheap air-heated fins The tube gasifier is used to gasify LNG, but the pure gasifier gasification will cause damage to the original environment due to the large amount of cold energy released by LNG gasification. The surrounding air absorbs cold energy to form cold fog. If the cold fog is not dealt with in time, it will affect the personal safety of operators and surrounding residential areas, reduce t...

Problems solved by technology

The construction of working equipment in this way is relatively complicated, and the construction cost is high. It is not suitable for large-scale popularization in LNG gasification stations. Ordinary demisting equipment generally uses the condensation effect of the screen plate to achieve demisting. This method is not only efficient Low, and, as the processing proceeds, its efficiency will be further reduced, affecting reliability
