Description

A single-side side-intake online pulse-cleaning bag-type dust collector

technical field

The utility model relates to a single-side side-intake type online pulse dust-cleaning bag-type dust collector, which belongs to the technical field of bag-type dust removal.

Background technique

At present, the bag filter used in the heating boiler is the air intake mode of the ash hopper. This structure is difficult for the dust to settle in the ash hopper during dust cleaning under the condition of high inlet wind speed, forming a secondary back-mixing, which makes the dust fall off after cleaning. The dust returns to the surface of the filter bag, resulting in greater resistance to the operation of the dust collector.

Contents of the invention

The purpose of this utility model is to provide a single-side side-intake type online pulse dust-cleaning bag filter, which adopts the method of increasing the area of the air duct of the dust-laden gas inlet and changing the flow mode of the airflow, reducing the inlet wind speed and enhancing the dust-cleaning effect , to reduce running resistance.

In order to achieve the above-mentioned purpose, the technical solution of the utility model is to provide a single-side side-intake type online pulse cleaning bag filter, which is characterized in that: it includes a lower box, and the lower box is equipped with filter bags arranged The formed filter bag dust removal area is equipped with an upper box and an ash hopper on the top and bottom of the lower box, an exhaust flue is provided on the upper box, and an air intake is provided on the side wall of the lower box. The flue, the air intake flue completely covers the side wall, an air intake uniform distribution plate is installed at the connection between the air intake flue and the lower box, and an ash hopper is installed at the connection between the lower box and the ash hopper to prevent back-mixing The device has a non-equal-diameter blowing pipe in the upper box, one end of the non-equal-diameter blowing pipe is connected to the air bag, and the other end is formed with multiple blowing ports, and each blowing port corresponds to a filter bag in the dust removal area of the filter bag .

Preferably, a cover plate is provided on the top of the upper box.

Preferably, a filter bag protection device is provided below each blowing port.

Preferably, the bottom of the intake flue adopts a slope floor, and the bottom of the intake flue communicates with the ash hopper.

The utility model arranges the flue on one side of the dust collector, and the flue gas enters the filter area from the outside of the lower box of the dust collector through the air intake uniform distribution plate. The area of the air inlet is the entire side wall of the lower box, so that the inlet wind speed is significantly reduced. The resistance of dust removal is reduced; at the same time, the movement direction of the side wall air intake airflow is not opposite to the direction of dust removal dust falling, avoiding secondary dust; the air intake flue adopts a slope bottom plate, which is not easy to accumulate dust, and large particles of dust can be released from the bottom along the bottom plate Set the slope bottom plate into the ash hopper for discharge.

Detailed ways

In order to make the utility model more obvious and understandable, a preferred embodiment is described in detail as follows in conjunction with the accompanying drawings.

As shown in Figures 1 to 3, the utility model provides a single-side side-intake type online pulse cleaning bag filter, which includes a lower box 10, and the lower box 10 is provided with filter bags 9 arranged to The formed filter bag dust removal area is provided with an upper box body 12 and an ash hopper 11 at the top and bottom of the lower box body 10 respectively. The side wall on one side of the lower box body 10 is provided with an air intake flue 1, the air intake flue 1 completely covers the side wall, the bottom of the air intake flue 1 adopts a slope bottom plate, and the bottom of the air intake flue 1 is in contact with the side wall. The ash hopper 11 communicates. An air intake uniform distribution plate 2 is provided at the junction of the air intake flue 1 and the lower box body 10 , and an anti-backmixing device 3 for the ash hopper is arranged at the junction of the lower box body 10 and the ash hopper 11 . The top of the upper box 12 is provided with an upper cover plate 5, and a non-equal diameter spray pipe 8 is arranged in the upper case 12. One end of the non-equal diameter spray pipe 8 is connected to the air bag 6, and the other end is formed with a plurality of Injection ports, each injection port corresponds to a filter bag 9 in the filter bag dust removal area, a filter bag protection device 7 is provided below each injection port, and an exhaust flue 4 is also provided on the upper box 12 .

When working, the dust-laden flue gas enters the dust collector through the air intake flue 1, and the flue gas is evenly distributed by the air intake uniform distribution plate 2, and then enters and exits the filter bag area 9 for dust filtration, and the filtered clean gas passes through the upper box 12 from the exhaust The gas flue 4 is discharged. The dust accumulated in the dust removal area of the filter bag passes through the injection pipe 8 to form an air wave to cause the filter bag 9 to expand rapidly and fall off due to impact vibration; the dust falling in the ash hopper 11 forms a secondary back-mixing and is then removed by the ash hopper anti-back-mixing device 3 to prevent it from entering the filter bag dust removal area 9 again.
