It is characterized in that: the first barrel 1 includes a right barrel section 11 and a left barrel section 12. The right barrel section 11 is connected to the left end of the second barrel 2 by a thread. A first cavity 13 is opened in the left barrel section 12. The inner circumferential wall of the first cavity 13 is provided with a protrusion 14. The multiple protrusions 14 are evenly distributed along the circumferential direction, and the distance between two adjacent protrusions 14 is 40 meters. A first cavity airflow channel is formed in the second cylinder 2; a second cavity 22 is provided in the second cylinder 2, an air inlet hole 21 is provided at the right end of the second cylinder 2, the air inlet hole 21 is connected / communicated with a compressed air source, and an annular groove 23 is provided on the inner circumferential wall at the left end of the second cavity 22; the inner cylinder 3 is installed in the second cavity 22, an axial channel 31 is provided at the right end of the inner cylinder 3, and a radial channel 32 is provided at the left end, and multiple radial channels 32 are evenly distributed along the circumferential direction, and no airflow hole is provided on the left end face of the inner cylinder 3, and the left end face of the inner cylinder 3 is flush with the left end face of the annular groove 23; a common connecting channel 15 is provided between the annular groove 23 and the first cavity airflow channel.

[0020] The compressed air flow path is: air inlet hole 21 →axial channel 31 →radial channel 32 →annular groove 23 →common communication channel 15 →first cavity air flow channel →first cavity 13 →injection hole 43 of nozzle head 4 .

[0021] The raised portion 14 is in the shape of an elongated strip and its cross section is in the shape of a fan. Figure 4 shown.

[0022] The center line of the protrusion 14 is arranged obliquely or spirally relative to the central axis of the cleaning nozzle.

[0023] The present invention improves the spray performance (such as spray force and / or spray speed) of the cleaning nozzle of the pulse bag separator under the same pressure compared with the existing cleaning nozzle, thereby improving the cleaning efficiency of the cleaning nozzle on the filter cartridge and improving the separation efficiency of the pulse bag separator.

Under different pressures of the supplied compressed air, the ring body 44 can be forced to move axially so that the ring body 44 can be located at different positions in the first cavity 13, so that the distance S is variable, such as Figure 3-4 shown.

[0026] Through the structural design of the nozzle head 4 of the present invention, the ring body 44 is forced to move axially under different supply compressed air pressures so that the ring body 44 can be located at different positions in the first cavity 13, so that the spacing S is variable, the axial length of the cleaning nozzle can be adjusted, and the injection performance of the cleaning nozzle (such as injection force and / or injection speed) can be adjusted, thereby improving the cleaning efficiency of the cleaning nozzle on the filter cartridge and improving the separation efficiency of the pulse bag separator.

Through the arrangement of the connecting holes 45, the airflow on the outer peripheral surface of the right nozzle head section 42 can flow into the nozzle through hole through the connecting holes 45, and the spray performance of the cleaning nozzle can be further adjusted.

[0028] Optionally, a spiral groove is provided in the injection hole 43 and / or the nozzle through hole, and a plurality of spiral grooves are evenly distributed along the circumferential direction.

[0031] The present invention can further improve the spraying performance (such as spraying force and / or spraying speed) of the cleaning nozzle by optimizing the design of the parameters of the diameters d1, d2, d3, and d4.
