Example 1

As shown in fig. 1 and 2, a dust collector with a pre-separation function includes a dust collector chamber 11, a filtering component 14, an ash bucket 15, an ash discharging device 16 and a pre-separation device, the pre-separation device is disposed on the ash bucket 15 and is respectively communicated with the ash bucket 15 and an air inlet, the filtering component 14 is disposed above the ash bucket 15, the filtering component 14 is respectively communicated with a back-blowing device 12 and an air outlet 13, the back-blowing device 12 and the air outlet 13 are disposed on the dust collector chamber 11, and the ash discharging device 16 is disposed at the bottom of the ash bucket 15 and is communicated with the ash bucket 15. The pre-separation device is used for screening and removing large-particle dust in dust-containing gas, and specifically, the pre-separation device comprises an air inlet channel 21 and a baffle 22 which are arranged on the upper portion of an ash bucket 15, the air inlet channel 21 is communicated with the ash bucket 15 through the baffle 22, the baffle 22 is fixedly arranged on the ash bucket 15, the baffle 22 is obliquely and downwards arranged, and an included angle between the baffle 22 and the air inlet channel 21 is an acute angle. After the dust-containing gas passes through the air inlet channel 21, dust particles therein collide with the baffle 22, kinetic energy attenuation is not obvious after the collision of smaller dust particles and the baffle 22, the smaller dust particles are still moved out at a higher speed after passing through the baffle 22 and enter the filter assembly 14 above the dust hopper 15 under the action of the fan, small particle dust is adsorbed on a filter bag of the filter assembly 14, and the filtered clean gas is discharged from the air outlet 13. After the large-volume dust particles collide with the baffle 22, the kinetic energy is obviously attenuated, the speed is reduced, the large-volume dust particles overcome the pressure of the fan under the action of self gravity and settle downwards, the large-volume dust particles directly enter the ash hopper 15 to be collected, the large-volume dust particles are prevented from entering and filtering the component 14 and causing damage to the component, and the pressure of the fan is adjusted according to the volume and the weight of the dust. Through the structure, dust with different particle sizes is filtered by the dust-containing gas at the baffle 22 and the filter assembly 14 in a grading way, the dust-containing gas flows from bottom to top, and the dust collection direction is from top to bottom, so that the counter-flow dust removal is completed. When the dust on the filter assembly 14 reaches a certain amount, the blowback device 12 blows air to the filter assembly 14, so that the dust in the filter assembly 14 falls off and enters the dust hopper 15, and finally is collected in the dust discharging device 16 and discharged by the dust discharging device 16.

Preferably, the baffle 22 is welded to the hopper 15 by a support bracket 23 to provide a passage for the settling of large particle dust and also to provide a space for the upward movement of small particle dust. The included angle between the baffle 22 and the air inlet channel 21 is 60 degrees, and the large-particle dust can be ensured to fall down to the lower part of the ash hopper 15 after colliding with the baffle 22. The baffle 22 is made of a corrosion resistant material to withstand long term scouring of dusty gases, preferably the baffle 22 is made of a low alloy high strength structural steel such as 16 manganese.
