[0023] Please refer to Figures 1-7 The utility model provides an embodiment: a dust removal equipment for power plant, including filter bucket 1, the inside of filter bucket 1 is equipped with first filter cavity 7 and second filter cavity 8, wherein, the filter member 2 being equipped with at the bottom of second filter cavity 8, and first filter cavity 7 still is equipped with drainage member 6, utilize filter member 2 present and filter the dust in gas, then, utilize drainage member 6 and introduce the airflow into first filter cavity 7, to make the airflow contact the purified liquid in first filter cavity 7, complete secondary filtration.

[0024] Wherein, the filter member 2 includes bottom cover 20, filter core 22 is installed on bottom cover 20, and through the air inlet pipe 21 being equipped with on bottom cover 20, the gas source is introduced to filter core 22, therefore, through bottom cover 20 and second filter cavity 8 connection, to place filter core 22 into second filter cavity 8, utilize air inlet pipe 21 and introduce the uncleaned gas source to filter core 22 inside at the same time, wherein, filter core 22 and bottom cover 20 air inlet pipe 21 screw thread cooperation facing second filter cavity 8 one side, complete the installation of filter core 22, also convenient to take down filter core 22 from bottom cover 20.

[0025] Specifically, the airflow after the filter element 22 flows to the second filter cavity 8 through the air outlet pipe 9 arranged on the second filter cavity 8, and is guided to the first filter cavity 7 through the flow guide 6, and after being contacted with the purification liquid in the first filter cavity 7, the airflow is discharged outward through the air outlet pipe 61 arranged on the upper end of the flow guide 6 after being purified.

[0026] As described above, since the first filter cavity 7 and the second filter cavity 8 are arranged in the filter barrel 1, and the two cavities are communicated through the air outlet pipe 9 and the flow guide 6, when the filter element 2 in the second filter cavity 8 filters the dust in the air source, and then flows to the first filter cavity 7, the filtered gas is discharged through the air outlet pipe 61 after being filtered by the purification liquid in the first filter cavity 7, so that the device can realize dry and wet separation, avoid the phenomenon of airflow channel blockage, and further improve the filtering efficiency while ensuring the smooth flow of the airflow.

[0027] Especially, since the airflow flows to the bottom of the first filter cavity 7 under the action of the flow guide 6, and flows upward after being fully contacted with the purification liquid, and is discharged through the air outlet pipe 61, the filtering effect is improved, and the structure of the device is simplified to reduce the use and maintenance cost of the device, and the participation of personnel during use is reduced.

[0028] Specifically, the flow guide 6 further includes an end cover 60 covering the first filter cavity 7 and a flow guide pipe 64 mounted on the end cover 60, and the airflow is introduced into the bottom of the first filter cavity 7 through the flow guide pipe 64. Through the above-mentioned mode, the flow guide 6 can be removed from the filter barrel 1 by disassembling the end cover 60, and vice versa, the end cover 60 is connected with the filter barrel 1, which is convenient for the installation of the flow guide 6. The end cover 60 and the bottom cover 20 are connected with the filter barrel 1 in a threaded cooperation mode.
