A terminal evaporative gas demisting device based on lng gasifier

Abstract

The invention discloses a terminal evaporated gas defogging device based on an LNG gasifier, which can effectively monitor the generation of cold fog during LNG gasification and remove it in time within the range of the fence. When there is no gasification task at the peak station, the present invention can stop running, and the present invention uses physical methods to process cold fog, further reducing energy consumption. The whole system structure is relatively simple and requires less investment, and it can take into account the economical issues of station investment when dealing with the problem of cold fog. The condensation treatment and collection assembly of the present invention can well realize the condensation treatment of the mist in the airflow, effectively ensure the collection ability of condensed water, improve the demisting effect, and prevent problems such as excessive humidity in the environment around the vaporizer.

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
