[0002] Furfural is the raw material for preparing many medicines and industrial products. Some derivatives of furfural have strong bactericidal ability and a very broad antibacterial spectrum. However, the raw materials for furfural production include corn cobs. Usually, corn cobs are manually put into the feeding port during feeding. During the manual feeding process, raw materials are often fed at the same time, resulting in collisions between corn cobs that have entered the feeding port, causing dust to rush out of the feeding port. If workers inhale dust for a long time, it will cause lung damage.

[0003] To solve the above problems, the prior art patent (CN215951457U) discloses a furfural manufacturing dust removal device and its dust reduction mechanism and filtering mechanism. The dust reduction mechanism is provided. Specifically, when workers put corn cob raw materials through the feeding port, the corn cobs enter the feeding box and collide to cause dust to fly. The water storage tank is started to pass water to the water pipe. The water passing water pipe introduces water into the first sprayer. The first sprayer humidifies the corn cobs entering from the feeding port with water mist. When the dust flying up through the water is about to rush out from the feeding port, it is intercepted by the mist sprayed by the first sprayer to prevent the dust from rushing out and being inhaled by the workers. The exhaust fan is started to suck air from the lower area of ​​the partition. The absorbed air is discharged to the exhaust port through the exhaust fan inside the exhaust pipe.

[0004] However, in the above-mentioned prior art, the dust reduction and filtering device cannot effectively remove harmful gases such as sulfur dioxide, ammonia and formaldehyde generated in the furfural production process only through the second sprayer, resulting in poor filtering effect.
