Further, the lower end of the main dust removal tank body 1 is provided with a dust collection discharge port 12, and the dust collection discharge port 12 is covered by a dust collection cleaning cover plate 11.
The working principle of the utility model is as follows:
gas enters the main dedusting tank body 1 through the dust-containing gas inlet pipe 2, the gas enters the second filter screen 5 and the first filter screen 4 in the air inlet direction due to the action of the air inlet flow guide plate 9, particles in the dust-containing air settle, and the gas enters the secondary settling chamber 8 through the gas guide hole 7 after flowing back from the lower section in the main dedusting tank body 1 and is discharged through the purified gas exhaust pipe 3.
Example 1: when gas enters the 3D dust remover in a pipeline with the diameter D, the gas enters the dust remover with the diameter D due to the P by using the gas state equation PV ═ NRT1V1＝NRT＝P2V2，P1π(D/2)2v1t1＝P2π(3D/2)2v2t2When the pipe and the gas are considered as a whole, the internal pressure is equal, P1＝P2Assuming that the time for the gas to pass through the cross-section is sufficiently short, as short as t1And t2The difference between them is negligible, the gas velocity v1＝9v2I.e. the velocity of the gas through the precipitator is reduced by a factor of two times the radius ratio. After the speed is reduced, the carrying capacity of the dust is weakened, and large particles can naturally settle under the action of gravity. In order to reduce the natural selection of the dust remover on the particle size and the density, a gas guide is arranged at the gas inlet of the dust remover "The diversion component with the function is induced by the fluid director to naturally settle towards the gravity direction no matter the size and the density of the particles, thereby solving the selectivity problem of the dust remover. In order to improve and subside efficiency, the mutual mirror image of the inside air current of filter screen reaches supplementary settlement in order to form "the cross-section" shape, improves and subsides efficiency to less equipment volume lets dust remover ability direct mount on gas conveying pipeline. Through calculation, the dust removal efficiency of the precipitator with the diameter of 3D reaches more than 95%.
Example 2: when the gas in the pipeline with the diameter D enters the dust remover with the diameter of 4D, the P is the gas state equation PV ═ NRT1V1＝NRT＝P2V2，P1π(D/2)2v1t1＝P2π(4D/2)2v2t2When the pipe and the gas are considered as a whole, the internal pressure is equal, P1＝P2Assuming that the time for the gas to pass through the cross-section is sufficiently short, as short as t1And t2The difference between them is negligible, the gas velocity v1＝16v2And the dust removal efficiency of the precipitator with the diameter of 4D is calculated to reach more than 99%.
The utility model discloses equipment is small, and the installation is more convenient (directly adorn on gas delivery official way), does not need power consumption and water, more energy-concerving and environment-protective. The original flow rate and pressure of the inlet air and the outlet air are not changed, and the safety risk is avoided. Through changing its natural settlement of gas flow direction induction and having solved most settler selectivity problem, through the supplementary structure of subsiding of "shape filter screen improvement settlement efficiency, solve the bulky problem of settler volume, more be fit for the precision dust removal of pipeline gas transport.
