负压除尘器主要依靠设备内部的负压环境实现除尘。当含尘空气经过负压除尘器时，空气在负压作用下被迅速吸入除尘器内，尘粒在负压作用下被吸附在除尘器内壁上，而清洁空气则通过除尘器顶部排出。相较于传统的正压除尘器，负压除尘器具有更高的除尘效率和更低的能耗。

The negative pressure dust collector mainly relies on the negative pressure environment inside the equipment to achieve dust removal. When dusty air passes through the negative pressure dust collector, the air is quickly sucked into the dust collector under the negative pressure, and dust particles are adsorbed on the inner wall of the dust collector under the negative pressure, while clean air is discharged through the top of the dust collector. Compared to traditional positive pressure dust collectors, negative pressure dust collectors have higher dust removal efficiency and lower energy consumption.

负压除尘器的设计原理简单但G效。其主要由吸尘管、过滤室、旋风分离器、集尘箱、引风机等部分组成。在负压除尘器的运行过程中，引风机产生的负压使得含尘空气进入吸尘管，随后进入过滤室。在过滤室内，大颗粒粉尘由于重力作用落入集尘箱，而细小粉尘则随气流进入旋风分离器。在旋风分离器中，细小粉尘受到离心力作用被甩向器壁，随后落入集尘箱。

The design principle of negative pressure dust collector is simple but G-efficient. It mainly consists of vacuum tubes, filter rooms, cyclone separators, dust collection boxes, induced draft fans, and other parts. During the operation of the negative pressure dust collector, the negative pressure generated by the induced draft fan causes dusty air to enter the suction pipe and then enter the filtering room. In the filtering room, large particles of dust fall into the dust collection box due to gravity, while small particles enter the cyclone separator with the airflow. In a cyclone separator, fine dust is thrown towards the wall by centrifugal force and then falls into the dust collection box.

负压除尘器的应用领域十分广泛，如矿业、化工、医药、食品加工、冶金等行业的生产车间和实验室。在这些场所中，由于生产过程或实验过程中产生的粉尘会对环境和人体健康造成危害，因此需要采取有效的除尘措施。

The application fields of negative pressure dust collectors are very extensive, such as production workshops and laboratories in industries such as mining, chemical, pharmaceutical, food processing, metallurgy, etc. In these places, effective dust removal measures need to be taken due to the harmful effects of dust generated during production or experimental processes on the environment and human health.

负压除尘器的出现为工业生产带来了诸多好处。其G效率的除尘效果降低了企业对于设备的投入成本。

The emergence of negative pressure dust collectors has brought many benefits to industrial production. The dust removal effect of its G-efficiency reduces the investment cost of environmental protection equipment for enterprises.

其次，负压除尘器的低能耗设计为企业节省了大量能源。此外，负压除尘器的维护成本较低，为企业降低了运营压力。

Secondly, the low energy consumption design of negative pressure dust collectors saves a lot of energy for enterprises. In addition, the maintenance cost of negative pressure dust collectors is relatively low, which reduces operational pressure for enterprises.

Z后，负压除尘器作为一种新型设备，对于提升企业形象和生产效率具有积*作用。

After Z, negative pressure dust collectors, as a new type of environmental protection equipment, have a positive effect on improving corporate image and production efficiency.
