Embodiment 1

[0017] refer to figure 1 with figure 2 The air inlet distributor of a pulse reverse blowing bag filter is shown, which includes a distribution ring support frame 2 connected to the air inlet pipe 1 and several stages of distribution rings 3, the air inlet pipe 1 and the distribution ring support frame 2 Fixedly connected, the distribution ring support frame 2 includes several skeletons, each of which is tapered, and the diameter of the distribution ring support frame 2 gradually decreases from the air inlet pipe 1 to the air outlet of the air inlet distributor. The ring 3 is a ring piece with a central through hole, the size of the central through hole of the distribution ring 3 decreases step by step, and the distribution ring 3 is fixed on the distribution ring support frame 2 at a certain angle.

Embodiment 2

[0019] As a further improvement of the present invention, on the basis of Embodiment 1, in order to adjust the direction of the airflow distribution, the airflow can be quickly and evenly diffused in the pulse blowback bag filter. When the air inlet distributor is placed horizontally, the distribution The included angle between the ring 3 and the vertical direction is 28°-35°.

Embodiment 3

[0021] As a further improvement of the present invention, on the basis of Embodiment 1, in order to make the amount of air distribution at all levels more average, the ring width between the inner ring and the outer ring of the distribution ring 3 is fixed; further, The ring width between the inner ring and the outer ring of the distribution ring 3 is 5cm--7cm.

Abstract

The invention discloses an air intake distributor of a pulse back flushing bag filter. The air intake distributor comprises a distributing ring bracing frame connected with an air-supply pipe and several grades of distributing rings; the air-supply pipe is fixedly connected with the distributing ring bracing frame; the bracing frame comprises a plurality of skeletons in taper arrangement; a diameter of the distributing ring bracing frame is lessened from the air-supply pipe to an outlet of the air intake distributor; the distributing rings are circular ring sheets equipped with central through holes; sizes of the distributing rings are decreased step by step; and the distributing ring is fixed on the distributing ring bracing frame at a certain angle. The air intake distributor of the pulse back flushing bag filter of the invention realizes more uniform air-flow distribution and facilitates working efficiency increase of the pulse back flushing bag filter.

Description

technical field [0001] The invention relates to an air distribution device, in particular to an air inlet distributor for a pulse reverse blowing bag filter. Background technique [0002] In the prior art, the carbon black powder can be collected by using the pulse blowback bag filter. The air inlet pipe of the pulse blowback bag filter is fed with airflow containing carbon black powder. After the airflow is blown to the filter bag, the gas will pass through the filter bag. The bag is discharged from the air outlet, and the carbon black powder will remain on the filter bag. During the collection of carbon black powder, the uniform diffusion and flow of the airflow has a greater impact on the collection efficiency of the carbon black powder. When the airflow spreads evenly, All filter bags can effectively filter carbon black. When the airflow is unevenly diffused, the local airflow density is high, which will lead to the accumulation of carbon black on individual filter bags,...
