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.

負壓除塵器的設計原理簡單但G效。其主要由吸塵管、過濾室、旋風分離器、集塵箱、引風機等部分組成。在負壓除塵器的運行過程中，引風機產生的負壓使得含塵空氣進入吸塵管，隨后進入過濾室。在過濾室內，大顆粒粉塵由于重力作用落入集塵箱，而細小粉塵則隨氣流進入旋風分離器。在旋風分離器中，細小粉塵受到離心力作用被甩向器壁，隨后落入集塵箱。

The design principle of negative pressure dust collector is simple but G-efficient. It mainly consists of vacuum pipes, filter chambers, 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 filter 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.

負壓除塵器的應用領域十分廣泛，如礦業、化工、醫藥、食品加工、冶金等行業的生產車間和實驗室。在這些場所中，由于生產過程或實驗過程中產生的粉塵會對環境和人體健康造成危害，因此需要采取有效的除塵措施。負壓除塵器的出現為這些行業提供了新的解決方案。

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. The emergence of negative pressure dust collectors provides new solutions for these industries.

以某礦業企業為例，該企業采用負壓除塵器進行礦料粉碎工序的粉塵治理。在生產過程中，礦料粉塵在負壓作用下被迅速吸入除塵器內，經過G效過濾和分離后，清潔空氣排出，而粉塵則被收集在集塵箱中方便后續處理。

Taking a mining enterprise as an example, it uses a negative pressure dust collector for dust control in the ore crushing process. During the production process, mineral dust is quickly sucked into the dust collector under negative pressure, and after being filtered and separated by G-effect, clean air is discharged. The dust is collected in a dust collection box for subsequent processing.

負壓除塵器的出現為工業生產帶來了諸多好處。其G效率的除塵效果降低了企業對于環保設備的投入成本。其次，負壓除塵器的低能耗設計為企業節省了大量能源。此外，負壓除塵器的維護成本較低，為企業降低了運營壓力。

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

后，負壓除塵器作為一種新型環保設備，對于提升企業形象和生產效率具有積*作用。

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