Embodiment 1

[0014] Such as figure 1 A natural gas liquefaction raw gas filter device based on real-time control is shown, which includes a filter kettle body 1, and a solid particle filter layer 2, a dehydration layer 3 and an acid gas filter layer 4 are sequentially arranged inside the filter kettle body 1, and the solid particle Activated carbon is arranged inside the filter layer 2, and molecular sieves are respectively arranged in the dehydration layer 3 and the pickling gas filter layer 4; The chamber 5 extends along the side wall of the filter kettle body 1 , the pickling gas collection chamber 5 is connected to the inside of the filter kettle body 1 through a collection pipe 6 , and a plurality of air pumps 7 are connected to the pickling gas collection chamber 5 .

[0015] As an improvement of the present invention, in the pickling gas collection chamber 5, a plurality of collection pipes 6 correspond to a plurality of air pumps 7, and each air pump 7 is arranged above the axial e...

Embodiment 2

[0018] As an improvement of the present invention, in the pickling gas collection chamber 5, each air pump 7 is connected to a heating chamber 8, and an electric heat source 9 is arranged inside the heating chamber 8. By adopting the above technical scheme, it can heat the air pump through the heating chamber, so that while the air flow generated by the air pump controls the pressure in the pickling gas filter layer, the temperature can also be effectively controlled, so that the acid The discharge and collection efficiency of scrubbing gas under high temperature is significantly improved.

[0019] The remaining features and advantages of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0021] As an improvement of the present invention, in the filter kettle body 1, the corresponding position of the pickling gas filter layer 5 is provided with a condensation jacket 10, which extends between the outer wall and the inner wall of the filter kettle body 1, and the condensation jacket The sleeve 10 communicates with a condensing agent tank 11 arranged outside the filter kettle body 1 . By adopting the above technical solution, the cooling jacket can be used to cool the acid-washed gas filter layer, so that the adsorption effect of the acid-washed gas filter layer can be improved under low temperature.

[0022] The remaining features and advantages of this embodiment are the same as those of Embodiment 2.

Abstract

The invention discloses a real-time control-based natural gas liquefied raw gas filtering device. The real-time control-based natural gas liquefied raw gas filtering device comprises a filtering kettle body; a solid particle filtering layer, a dewatering layer and an acid gas filtering layer are arranged in the filtering kettle body; activated carbon is arranged in the solid particle filtering layer; molecular sieves are respectively arranged in the dewatering layer and the acid gas filtering layer; an acid gas collecting chamber is formed in the corresponding position of the acid gas filtering layer in the filtering kettle body, and extends along the side wall of the filtering kettle body; the acid gas collecting chamber is connected with the interior of the filtering kettle body through a collecting pipeline; the acid gas collecting chamber is connected with a plurality of air pumps. According to the real-time control-based natural gas liquefied raw gas filtering device, solid particles, water and the acid gas in raw gas can be effectively collected, meanwhile, the filtering device disclosed by the invention can be kept in a good filtering state by performing real-time precipitation treatment on the acid gas, so that the filtering efficiency and the effect of the filtering device are both improved.

Description

technical field [0001] The invention relates to the field of fluid machinery, in particular to a natural gas liquefaction raw gas filtering device based on real-time control. Background technique [0002] Filtration treatment of raw natural gas is one of the necessary processes in the liquefaction process, which is used to remove solid particles, moisture and acid gases such as carbon dioxide and sulfur dioxide in the raw natural gas. The existing raw gas filtration equipment only adopts regular replacement to maintain the filter element during the filtration process, and when there are many impurities in the raw gas, the filter medium is prone to saturation, which makes it impossible for the subsequent natural gas to be imported. Thoroughly filter. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a natural gas liquefaction raw gas filtering device based on real-time control, which can effectively filter and adso...
