Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: a filter cartridge dust remover with the discharge concentration below 5mgNm3 comprises an air outlet pipe 1, wherein the air outlet pipe 1 is fixedly arranged on the filter cartridge dust remover;

the air outlet pipe 1 is arranged in a spiral shape, the lower end of the air outlet pipe 1 is communicated with a pipeline of the filter cartridge dust remover, and the upper end of the air outlet pipe 1 is provided with three sliding chutes which are uniformly distributed.

A sliding rod 3 is horizontally connected in the sliding chute at the upper end of the air outlet pipe 1 in a sliding manner, the inner side end of the sliding rod 3 is fixedly connected with the outer side end of a spring 31, and the inner side end of the spring 31 is fixedly connected with the inner wall of the sliding chute.

The movable ring 2 is arranged at the end part of the air outlet pipe 1 and is connected with the air outlet pipe 1 in a sliding way.

The outer end of the sliding rod 3 is fixedly connected with the side edge of the movable ring 2, and a sealing gasket 21 is arranged on the side wall of one side of the movable ring 2 facing the air outlet pipe 1.

The inner side of the movable ring 2 is fixedly connected with three drying frames 22, the drying frames 22 evenly divide the inner side of the movable ring 2 into three equal parts, and a filter screen 23 is filled between the drying frames 22 and the movable ring 2.

The heating pipes 4 are respectively installed in one side of the drying rack 22 facing the air outlet pipe 1, the middle part of the side of the drying rack 22 is horizontally connected with an expansion rod 51 in a sliding mode, and the inner side of the expansion rod 51 and the inner wall of the drying rack 22 are respectively fixedly connected with two ends of an expansion spring 52.

The other end of the telescopic rod 51 is fixedly connected with a closing cover 5, the cross street of the closing cover 5 is the same as the cross street of the three drying racks 22, and the two are connected in a sealing way.

The working principle is as follows: the air purified by the filter cartridge deduster moves upwards through the lower end of the air outlet pipe 1 and passes through the pipe wall of the spiral air outlet pipe 1, so that the air is periodically collided with the pipe wall under the action of centrifugal force, redundant moisture in the air is thrown out and attached to the pipe wall of the air outlet pipe 1, and the air flows downwards along the inner wall of the air outlet pipe 1 under the action of self gravity until flows out of the air outlet pipe 1.
