The return air filtering device comprises a frame body, the frame body is of a hollow rectangular structure, the upper edge of the outer wall of the frame body is fixedly connected with a connecting flange plate, the frame body is connected to the top of a subway carriage through the connecting flange plate, one end in the frame body is rotationally connected with a sealing plate, and the middle of the side wall of one side of the sealing plate is detachably connected with a concentration box; compared with the prior art, the invention has the following advantages: the plurality of filter plates are connected in the inner tank, and each filter plate is filled with different filter materials, so that various filter effects can be realized, the filter plates are provided with the filter holes, so that the filter plates have a double filter effect, the filter holes can filter impurities such as dust, and the filter efficiency is improved. And the internal filter material can filter some pollutants in the air, so that the dual-purification effect is achieved, the problems of incomplete purification and the like caused by a single filter structure are solved, the filtering and purifying effects are improved, and the purity of the return air is ensured.
本发明公开了一种地铁空调用回风过滤装置,包括框体,框体为中空的矩形结构,框体外壁上边沿固定连接有连接法兰板,框体通过连接法兰板连接在地铁车厢顶部,框体内一端转动连接有封板,封板的一侧侧壁中间可拆卸式连接有集中箱,本发明具有以下优点:在内槽内部连接多个过滤板,且在每个过滤板内填充不同的滤材,这样就能实现多种过滤的效果,且过滤板本身开设有滤孔,这样就能使过滤板具有双重过滤的效果,滤孔能过滤灰尘等杂质,而内部的滤材能够针对空气中的一些污染物进行过滤,实现双重净化的效果,避免单一过滤结构导致的净化不彻底等问题,提高过滤净化的效果,保证回风空气的纯净。
