[0019] The singular forms "a", "said" and "the" used in the specification are intended to include plural forms unless clearly indicated otherwise. The terms "comprise", "include" and "contain" used in the specification mean that the claimed features exist, but do not exclude the existence of one or more other features. The term "and / or" used in the specification includes any and all combinations of one or more of the related listed terms.

[0020] In the description, when it is said that one element is "on", "fixed to", "connected to", "joined to" or the like another element, the element can be directly on, fixed to, connected to, joined to or in contact with the other element, or there can be an intervening element. In the description, when it is said that one feature is arranged adjacent to another feature, it can mean that the feature has a portion overlapping the adjacent feature or a portion above or below the adjacent feature.

[0021] It is to be understood that the terms "first", "second", and so on can be used herein to describe various elements, but the elements should not be limited by these terms. The terms are only used to distinguish one element from another. Therefore, a first element can be referred to as a second element without departing from the teachings of the present application.

[0022] Exemplary embodiments of the present application will be described below with reference to the accompanying drawings. It is to be understood, however, that the present application can be embodied in many different forms and should not be limited to the embodiments described below. It is also to be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all the drawings, the same reference numerals denote the same or functionally similar elements.

[0023] Figure 1 The overall structure of such a large gas filtration system facilitating maintenance is shown. Given the large size of the large filtration pry, the tank assembly is inconvenient to maintain, and therefore the components are fixed by a fixed frame 70, which is equivalent to reducing the floor space occupied by the vertical arrangement of the pry body. At the same time, by lifting the tank assembly, the bottom can accommodate a small car 60 for moving and unloading, facilitating the unloading and maintenance of the tank assembly.

[0024] In combination with reference Figure 2 And Figure 3 The first tank 10 and the second tank 20 are placed in the central position of the fixed frame 70, which is conducive to overall stability. The pre-filter 30 and the maintenance exhaust filter 40 are arranged around the fixed frame 70. Specifically, the fixed frame 70 is composed of upwardly extending first support column 71 and second support column 72. A pair of cross beams 73 are connected between the first support column 71 and the second support column 72 to strengthen the lateral strength of the fixed frame 70. The pre-filter 30 is fixedly arranged on the second support column 72. The tank assembly composed of the first tank 10 and the second tank 20 is arranged and fixed between the cross beams 73, and the bottom of the first tank 10 and the second tank 20 is suspended. The first tank 10, the second tank 20, the pre-filter 30 and the maintenance exhaust filter 40 are all connected by pipelines 50, and the pipelines 50 are fixed by using the points on the first support column 71, the second support column 72 and the cross beams 73.

[0025] A maintenance platform is also provided on the top of the fixed frame 70 for operating the tank assembly from the top. The maintenance platform is composed of a flat plate 77 provided on the first support column 71 and the second support column 72 and a railing 75 extending upward from the periphery of the flat plate 77. A plurality of foot steps 74 are arranged on the side of the first support column 72 for personnel to climb onto the maintenance platform. The foot steps 74 are arranged in a staggered manner with the pre-filter 30 on the second support column 72. Openings 76 are also provided on the side of the railing 75 for personnel to enter from the foot steps 74 after climbing onto the flat plate 77.

[0026] In order to achieve a higher filtering efficiency, the height of the first tank 10 and the second tank 20 is designed to be greater than 2200mm and the width is designed to be greater than 840mm, as the tanks are filled with filtering materials for filtering gas. In one embodiment, the filtering materials are molecular sieve or activated carbon. The filtering materials need to be replaced periodically. The large volume makes it difficult to disassemble the tank assembly. The integrated hollow design described above allows the operator to directly unload the filtering materials from the bottom without moving the tanks, load the filtering materials away by the trolley 60, and then refill the filtering materials into the tanks from the top on the maintenance platform.
