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(fù)壓除塵器的設(shè)計(jì)原理簡(jiǎn)單但G效。其主要由吸塵管、過濾室、旋風(fēng)分離器、集塵箱、引風(fēng)機(jī)等部分組成。在負(fù)壓除塵器的運(yùn)行過程中，引風(fēng)機(jī)產(chǎn)生的負(fù)壓使得含塵空氣進(jìn)入吸塵管，隨后進(jìn)入過濾室。在過濾室內(nèi)，大顆粒粉塵由于重力作用落入集塵箱，而細(xì)小粉塵則隨氣流進(jìn)入旋風(fēng)分離器。在旋風(fēng)分離器中，細(xì)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(fù)壓除塵器的應(yīng)用領(lǐng)域十分廣泛，如礦業(yè)、化工、醫(yī)藥、食品加工、冶金等行業(yè)的生產(chǎn)車間和實(shí)驗(yàn)室。在這些場(chǎng)所中，由于生產(chǎn)過程或?qū)嶒?yàn)過程中產(chǎn)生的粉塵會(huì)對(duì)環(huán)境和人體健康造成危害，因此需要采取有效的除塵措施。負(fù)壓除塵器的出現(xiàn)為這些行業(yè)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(yè)企業(yè)為例，該企業(yè)采用負(fù)壓除塵器進(jìn)行礦料粉碎工序的粉塵治理。在生產(chǎn)過程中，礦料粉塵在負(fù)壓作用下被迅速吸入除塵器內(nèi)，經(jīng)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(xù)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(fù)壓除塵器的出現(xiàn)為工業(yè)生產(chǎn)帶來了諸多好處。首先，其G效率的除塵效果降低了企業(yè)對(duì)于環(huán)保設(shè)備的投入成本。其次，負(fù)壓除塵器的低能耗設(shè)計(jì)為企業(yè)節(jié)省了大量能源。此外，負(fù)壓除塵器的維護(hù)成本較低，為企業(yè)降低了運(yùn)營(yíng)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.
