[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments (for the convenience of description and understanding, the following is a schematic diagram of the present invention). Figure 1 Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0018] See also Figure 1-3 The utility model provides a technical solution: a chlorine gas filtering device, comprising a filter box 1, wherein both ends of the filter box 1 are respectively provided with an air inlet pipe 2 and an air outlet pipe 3, a partition plate 4 is provided inside the filter box 1, and the partition plate 4 divides the inside of the filter box 1 into two channels, and at least two filter elements 5 are evenly distributed in each channel. Through the multiple filter elements 5 in the two channels, the impurities in the chlorine gas can be fully filtered to ensure the filtering quality, and at the same time, the service life of the filter element 5 can be extended to save costs. The upper outer side surface of the filter element 5 is symmetrically provided with a fixing block 10, and the fixing block 10 is connected to the surface of the filter box 1 by a fixing bolt 11. Due to the existence of the partition plate 4, the length of the filter element 5 is shortened by at least half. When replacing, the filter element 5 can be quickly pulled out for replacement, which saves the replacement time of the filter element 5 and does not affect the collection of chlorine gas.

[0019] Furthermore, in order to facilitate the placement of the filter element 5 , a groove 6 adapted to the filter element 5 is provided on the surface of the partition plate 4 , and the bottom of the filter element 5 fits with the bottom of the groove 6 .

[0020] Furthermore, in order to ensure that the bottom of the filter element 5 is completely fitted with the bottom of the groove 6, a positioning column 7 is provided in the groove 6, and a positioning groove 8 adapted to the positioning column 7 is provided at the bottom of the filter element 5. When the groove 6 at the bottom of the filter element 5 is aligned with the positioning column 7 and is fully inserted, the bottom of the filter element 5 is completely fitted with the bottom of the partition 4.

[0021] Furthermore, in order to prevent chlorine leakage, a rubber pad 12 is provided between the fixing block 10 and the surface of the filter box 1 .
