Dust removal equipment


除尘设备吸尘罩图片

Brief introduction of dust extraction equipment hood:


1%-3% 是很难,但是把除尘设备的吸尘罩效果提高 1%-%3 要简单很多。 The dust extraction hood of the dust removal equipment occupies a large position in the energy-saving production of the dust removal equipment. It is difficult to increase the dust removal power of the dust removal equipment and the effect of the fan by 1% -3% , but it is difficult to improve the dust extraction hood of the dust removal equipment. %-% 3 is much simpler.


:除尘设备吸尘罩的位置 1 : Location of the dust extraction hood of the dust removal equipment

 

① Where the suction hood is designed, consider removing the positive pressure inside the suction hood, keeping the suction hood negative pressure average, and controlling that the dust-containing gas will not go out of the suction hood, and reduce the amount of powder. For some crushing and transportation equipment, the dust extraction hood should be protected from dust and gas centers, do not suck out a lot of powder

 

② During the process of conveying hot materials, the dust extraction hood should be installed on the head of the closed hood, or the upper and lower air inlets should be installed at the feeding point and receiving point.

③ Avoid access to some open holes, such as: operation orifices, maintenance ports, inlet and outlet, etc., to prevent the gas outside the hood from being sucked in and waste resources.

④ The place where the dust extraction hood is installed must not affect the operation, maintenance and production of workers.

⑤ A section of pipeline connected to the side of the dust extraction hood is best set in a straight line to prevent some materials from blocking the pipeline.

① It should be possible to use closed hoods or half-closed hoods for dust sources with resources to prevent inhalation of air other than dust.

 

一般为了使吸尘罩内气流平均开来,降低阻力一般使用伞形式吸尘罩。 ②The polishing and dust removal equipment is generally used to make the air flow in the dust extraction hood even, and to reduce the resistance, an umbrella dust extraction hood is generally used.


③ When air is discharged from the sealing cover and the material bin, there is no need to consider that the powder is sucked out. Instead of installing a dust collecting hood, the air pipe can be directly connected to the sealing cover or the silo. A reducer should be installed between the two suction hoods to reduce the resistance in the pipe.

 

:除尘设备吸尘罩 风速计算 3 : wind speed calculation of dust extraction hood of dust removal equipment

 

① The average wind speed of the mouth of the dust extraction hood should not be too high to prevent the extraction of powder and waste of resources. Generally, the seal cover and small, light and thin materials are adopted. The average wind speed of the dust cover cover should be designed to be small. 大于 3m/s. When local sealing is adopted, the average wind speed design of the mouth of the dust extraction hood is generally not greater than 3m / s.

 

② When the dust extraction hood of the dust removal equipment cannot be designed with a sealed hood, and when an open mask is used to handle the dust, the wind speed at the mouth of the dust hood should be designed and calculated according to the two sides of the hood or blower hood.
