Description

Gas filtering equipment containing oily dust

Technical Field

The utility model belongs to the technical field of gas filtration equipment, concretely relates to gas filtration equipment who contains oily dust.

Background

Oily dust mainly refers to oil fume dust, oil mist dust or other oil-containing particulate matter dust. At present, most of oily dust filters used in various industries are metal or plastic wire mesh type, cloth bag type, polyester round type, baffle plate impact type, cyclone centrifugal type, electrostatic trapping type and other types of filters.

The metal or plastic wire mesh type, cloth bag type and polyester round type filters have high filtering precision, but because the oil substances have high viscosity, and the dust is soaked by the oil substances after being mixed with the dust, the soaked dust becomes high-viscosity dust particles, when the dust passes through the metal or plastic wire mesh type, cloth bag type and polyester round type filters, the dust is adhered to the surfaces of the filters and is difficult to clean, in order to ensure the normal operation of equipment and not delay the production, only a new filter is replaced again, the operation cost of the equipment is increased, the replaced filter cannot be reused, and becomes secondary pollutants, and the secondary pollution is increased.

The baffle plate impact type filter adopts the filtering principle that the baffle plate is impacted by airflow to ensure that oily dust is adhered to the filter so as to achieve the aim of removing dust; the principle of the cyclone centrifugal filter is that the oily dust is adhered to the inner wall of the equipment under the action of centrifugal force by utilizing the high-speed rotation of airflow on the inner wall of the equipment, so that the aim of removing dust is fulfilled. Although dust removal can be achieved, the removal rate of the oily dust is very low, and the expected treatment effect is difficult to achieve.

The electrostatic trapping filter adopts the filtering principle that high-voltage electric field discharge is utilized, when airflow passes through the inside of equipment, oily dust particles are charged at one end, and then the dust particles are captured and removed at the other end, so that the aim of dust removal is fulfilled; when dust is trapped on the electric field polar plate, the dust is accumulated on the discharge polar plate, when the dust is accumulated to a certain thickness, the dust trapping and removing efficiency is reduced, in order to ensure the normal operation of the equipment and not delay the production, the equipment needs to be cleaned, maintained and maintained, and the normal operation maintenance work of the equipment is increased; meanwhile, the electrostatic trapping filter adopts the principle of high-voltage discharge, and oil mist dust, oil smoke dust and oily dust are all inflammable and explosive dust due to oiliness, so that great safety risk exists when the electrostatic trapping filter is used.
