[0013] Beneficial Effects

[0014] The beneficial effects of the utility model are:

[0015] The dust particles generated by the boiler during operation due to incomplete combustion of biofuel enter the capture chamber through the smoke inlet pipe. The water inlet chamber at the top of the capture chamber provides a water source for the capture tube. The water source enters the capture tube and is then sprayed out from the water atomization nozzle through the capture tube. The water mist generated by the water atomization nozzle captures the dust particles. The water mist beads with dust particles attached fall onto the bottom wall of the capture chamber under the action of gravity. After the water mist gathers to a certain amount on the bottom wall of the capture chamber, a water surface is formed. Due to the action of buoyancy, the captured dust particles will be suspended on the water surface. When the water surface height reaches the connecting pipe, the dust particles on the water surface enter the recovery chamber through the connecting pipe. The filter plate set in the recovery chamber filters the dust particles. After a certain amount of dust particles are collected in the recovery chamber, the worker empties the water in the body and then opens the removal door to remove the dust particles from the recovery chamber from the recovery port. The removed dust particles can be used as fuel again after drying, thereby achieving the effect of recovering a large amount of dust particles generated by incomplete combustion of biofuel in the flue gas.

[0026] A specific application of this embodiment is:

[0027] When in use, dust particles generated by the boiler during operation enter the capture chamber 12 through the smoke inlet pipe 2, and the water in the water tank 6 is filled into the water inlet chamber 3 through the water inlet pipe 62 and the water inlet pump 61.

The water mist generated by the water atomization nozzle 32 captures the dust particles, and the water mist beads with dust particles attached fall onto the bottom wall of the capture chamber 12 under the action of gravity. The worker can observe the capture situation in the capture chamber 12 through the observation plate 81 for observation. When the water mist gathers to a certain amount on the bottom wall of the capture chamber 12, it forms accumulated water. The captured dust particles are suspended on the water surface due to the buoyancy. The water mist continues to capture and the water surface continues to rise. When the water surface reaches the connecting pipe 4, the dust particles on the water surface enter the recovery chamber 13 through the connecting pipe 4. The filter plate 5 set in the recovery chamber 13 filters the dust particles. The water flows to the top of the filter plate 5, and the dust particles are blocked in the recovery frame 7. When a certain number of dust particles are collected in the recovery frame 7, the worker drains the water in the body 1 through the suction pipe 64 and the stream water pump, and then opens the removal door 52 through the tool, pulls the pull-out recess 71 to pull out the recovery frame 7, and the muddy dust particles are taken out from the recovery chamber 13. The dust particles taken out can be used as fuel again after drying.

[0028] If the worker finds dust particles accumulated in the capture chamber 12 through the observation window, the worker can enter the capture chamber 12 by opening the maintenance door 9 during shutdown to directly collect the dust particles in the capture chamber 12 .

[0029] In summary, through the above steps, the effect of recovering a large amount of dust particles in the flue gas generated by incomplete combustion of biofuel is achieved.
