The main classification of industrial dust collectors and places for attention
The main classifications of industrial dust collectors are as follows:
(1) Inertial dust collector This is a kind of dust removal equipment that uses the inertia force of dust in motion to be greater than the inertia force of gas to separate dust from dust-containing gas. This type of dust collector has a simple structure and low resistance, but has low dust removal efficiency, and is generally used for primary dust removal.
(2) Electrostatic precipitator When the dust-containing gas in the electrostatic precipitator is ionized by a high-voltage electric field, the dust particles are charged and under the action of the electric field force, the dust particles are deposited on the electrode, thereby separating the dust particles from the dust-containing gas. A dust removal equipment. It can effectively recover the dust in the gas to purify the gas. Various electrostatic precipitators have developed faster than other precipitators due to their advantages such as high efficiency, low resistance, suitable for high temperature, and removal of fine dust, but they have large investment. With regard to reducing the power consumption of the electrostatic precipitator, the use of air-conditioning technology enables high-resistance dust-containing gas to also obtain good results, so that the operation of the precipitator is in the best condition and the efficiency of improving the dust removal efficiency is being studied.
(3) Wet type dust collector This type of dust collector makes the dust-containing gas in contact with water or other liquids, and uses the inertia collision of water droplets and dust particles and other effects to separate the dust particles from the air stream. The wet dust collector uses water as a medium, so it is suitable for non-fibrous, dust-containing gas that can be cooled and does not chemically react with water. It is not suitable for removing sticky dust. Wet dust collectors have the advantages of low investment, simple operation, small footprint, and can simultaneously clean harmful gases, cool and humidify dusty gases, and so on. It is especially suitable for the treatment of high temperature and high humidity and the purification of explosive dangerous gases, but because water is used as the purification substance, it will bring secondary pollution.
In the use of industrial dust collectors, attention should be paid to the use of the machine in flammable places. Under high temperature and no filter, it is prohibited to use, otherwise it will cause explosion or high temperature heat will burn people's healthy complexion. Ensure that the industrial dust collector is unblocked and prevent short-circuiting of the power supply. After using the industrial dust collector, cut off the power supply.
