[0030] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0031] like Figures 1 to 4 As shown, this utility model provides a high-efficiency chemical gas filter with a separation mechanism, including a protective shell 1, an inlet pipe 2, an exhaust pipe 3, a backflush inlet pipe 4, a backflush exhaust pipe 5, a separation mechanism 8, and a filter body 6. The protective shell 1 is provided with an openable inspection door 11, and the protective shell 1 is used to protect its internal parts.

[0032] The intake pipe 2, the filter body 6, and the exhaust pipe 3 are connected in sequence, and the filter body 6 is installed inside the protective shell 1. The intake pipe 2 includes an intake main pipe 21 and intake branch pipes 22. The intake main pipe 21 passes through the bottom of the protective shell 1 and extends into the interior of the protective shell 1. Multiple intake branch pipes 22 are distributed at equal intervals along the circumference of the intake main pipe 21 and are connected to the intake main pipe 21.

[0033] The exhaust duct 3 includes a main exhaust pipe 31 and exhaust branch pipes 32. The main exhaust pipe 31 passes through the top of the protective shell 1 and extends to the outside of the protective shell 1. Multiple exhaust branch pipes 32 are evenly spaced along the circumference of the main exhaust pipe 31 and are connected to the main exhaust pipe 31. The number of exhaust branch pipes 32 is the same as that of the intake branch pipes 22. That is, each intake branch pipe 22, filter body 6, and exhaust branch pipe 32 can form a path and can filter the chemical gases in that path.

[0034] In operation, the air inlet of the main air intake pipe 21 is connected to the chemical gas storage tank, and the chemical gas passes through the main air intake pipe 21, the intake branch pipe 22, the filter body 6, the exhaust branch pipe 32 and the exhaust main pipe 31 in sequence.

[0035] The backflush intake pipe 4, the filter body 6, and the backflush exhaust pipe 5 are connected in sequence. Each exhaust branch pipe 32 is connected to a backflush intake pipe 4, and the air inlet of the backflush intake pipe 4 is connected to a blower. Each intake branch pipe 22 is connected to a backflush exhaust pipe 5, and the air outlet of the backflush exhaust pipe 5 is detachably connected to a dust collection mechanism 7.

[0036] The dust collection mechanism 7 includes an upper box 71 that is detachably connected to the outlet of the back-blowing exhaust pipe 5 and a lower box 72 that is detachably disposed at the bottom of the upper box 71. A first filter 73 is provided at the bottom of the upper box 71, and an exhaust port 74 is provided on the side wall of the lower box 72, with a second filter 75 fixedly disposed within the port 74. The aforementioned detachable connection can be achieved using an interference fit.

[0037] Isolation mechanisms 8 are installed on the intake branch pipe 22, exhaust branch pipe 32, backflush intake pipe 4, and backflush exhaust pipe 5 to isolate gas flow. Isolation mechanism 8 can be a valve. When isolation mechanism 8 is closed, it can block gas from entering each pipeline.

[0038] In use, open the isolation mechanisms 8 on all intake branch pipes 22 and all exhaust branch pipes 32, and close the isolation mechanisms 8 on all backflush intake pipes 4 and all backflush exhaust pipes 5. Then connect the intake port of the main intake pipe 21 to the chemical gas storage tank. The chemical gas passes sequentially through the main intake pipe 21, intake branch pipes 22, filter body 6, exhaust branch pipes 32, and exhaust main pipe 31, completing the filtration of the chemical gas. When the filter body 6 needs cleaning, close the isolation mechanism 8 of one intake branch pipe 22, and correspondingly close the isolation mechanism 8 of the exhaust branch pipe 32 corresponding to that intake branch pipe 22. At this time, the other pipelines continue filtration normally. Open the isolation mechanisms 8 of the backflush exhaust pipes 5 and backflush intake pipes 4 corresponding to the aforementioned intake branch pipes 22 and exhaust branch pipes 32, and connect the backflush intake pipes 4 to the blower. When the blower is turned on, air passes sequentially through the backflush intake pipe 4, exhaust branch pipe 32, filter body 6, intake branch pipe 22, backflush exhaust pipe 5, and dust collection mechanism 7, and is finally discharged through the outlet 74, thus completing the backflush cleaning of filter body 6. The smoke and dust impurities backflushed off filter body 6 are collected in dust collection mechanism 7.

[0039] The above methods can be used to clean each filter body in turn.

[0040] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
