Oil mist removing device

Abstract

The invention discloses an oil mist removing device which is used for removing oil mist from polluted air in a workshop. An air conditioning unit is arranged in the workshop. The oil mist removing device comprises an air return pipeline unit and an oil mist purifying unit arranged outside the workshop, wherein the air return pipeline unit comprises a main air return pipe and a first fan assembly which are arranged above the workshop; an air return opening is formed in the main air return pipe, and the first fan assembly sucks polluted air into the main air return pipe through the air return opening; and an inlet of the oil mist purifying unit communicates with an outlet of the main air return pipe, an outlet of the oil mist purifying unit communicates with an air inlet of the air conditioning unit, polluted air enters the oil mist purifying unit through the main air return pipe to be subjected to oil mist removal, and then the polluted air is discharged into the workshop from an air outlet of the air conditioning unit. According to the oil mist removing device, on the premise that the purification efficiency is guaranteed, the space position of a working area is not occupied, air in a workshop is circulated, purified and flows, the energy consumption of an air conditioner is reduced, and the operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of ventilation systems, in particular to an oil mist removal device. Background technique [0002] In the existing dust removal system technology, the oil mist is generally extracted from the source by using the suction pipe, suction hood, etc. or the traditional integral direct suction and exhaust system. However, there is a problem that part of the oil mist is distributed to the entire workshop. The treatment method of extracting oil mist from the source cannot control the oil mist in the entire workshop; secondly, during the machining process, a large amount of oil mist and hot gas are generated. Under the action of the thermal suspension force generated by the difference, it spreads around the machine tool, making the concentration of oil mist in the workshop higher and higher. If the oil mist is treated by directly discharging the air in the entire machining workshop, if the workshop where the oil mist...
