Description

A bag dust collector with a diversion device

technical field

The utility model relates to the technical field of bag dust removal, in particular to a bag dust collector with a flow diversion device.

Background technique

In industrial production, a large amount of waste gas mixed with solid particles and air will be produced. If this waste gas is directly discharged into the atmosphere, it will pollute the environment and affect the health of people or other organisms. The existing dust collectors include cyclone dust collectors, wet dust collectors, filter dust collectors, electrostatic precipitators and bag-type dust collectors. The bag-type dust collectors are widely used in large, medium and small factories due to their simple structure and convenient use. . However, in the current bag filter, when the dusty gas passes through the dust bag, the airflow speed is faster, which not only has a greater impact on the filter bag, but also reduces the service life of the filter bag, and the contact time between the filter bag and the airflow is relatively short. , the dust in the air cannot be fully removed, and the dust removal effect is poor; and after a long time of use, a lot of dust will adhere to the bag, which will reduce the dust removal efficiency.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in Figure 1, a bag filter with a flow diversion device includes a box body 1, the lower part of one side of the box body 1 is provided with an air inlet 2, the upper part of the other side is provided with an air outlet 3, and the air inlet 2 The air outlet end of the box is provided with a flow diversion device, and the inside of the box body 1 is provided with a flower plate 4. Above the flower plate 4 is a clean air chamber 5 that communicates with the air outlet 3. The filter chamber 6 and the flower plate 4 are provided with a number of air outlet holes 7, and the filter chamber 6 is provided with a number of cylindrical filter bags 8 with one end open. Periphery, the bottom of the filter bag 8 is provided with an end cover 9, the inner wall of the filter bag 8 is provided with a number of support rods 10 whose bottom ends are connected to the end cover 9, the top of the box body 1 is provided with a cylinder 11, and the lower end of the cylinder 11 is provided with There is a telescopic rod 12 whose bottom end extends into the inside of the filter bag 8. A rocker 13 is hinged on the telescopic rod 12. The other end of the rocker 13 is hinged to the support rod 10. The bottom of the box body 1 is provided with a conical ash bucket 14.
