Detailed Description
As shown in fig. 1, the oil-mist separation device of the oil-gas discharge system is installed between oil-gas discharge pipelines 1, the lower end of the oil-gas discharge pipeline 1 is communicated with an oil tank, and a smoke exhaust fan 6 is arranged on the oil-gas discharge pipeline 1. The oil mist separation device comprises a separation outer cylinder 2, a steel wire filling net 3, an oil return pipe 5 and a separation inner cylinder 8; the separating outer cylinder 2 is of a cylindrical structure, and the upper end and the lower end of the separating outer cylinder are provided with openings; the separation outer cylinder 2 is vertically arranged between the oil and gas exhaust pipelines 1 at the upper part of the smoke exhaust fan 6; openings at the upper end and the lower end of the separation outer cylinder 2 are communicated with the oil and gas exhaust pipeline 1, so that the separation outer cylinder 2 is connected between the oil and gas exhaust pipeline 1 in series; so that the oil gas can flow through the inside of the separation outer cylinder 2 from bottom to top.
As shown in fig. 1, the oil mist separation device of the oil gas discharge system has a cylindrical separation inner cylinder 8, an upper end of which is closed and a lower end of which is opened; the diameter of the outer cylinder of the separation inner cylinder 8 is smaller than that of the inner cylinder of the separation outer cylinder 2, and the separation inner cylinder is vertically arranged in the separation outer cylinder 2. The lower opening of the separation inner cylinder 8 is connected with the inner wall of the separation outer cylinder 2 through an annular plate 10; the annular plate 10 is of a structure with a high inner ring and a low outer ring, and the vertical section of the annular plate is in a splayed shape; the inner ring of the annular plate 10 is matched with the size of the lower opening of the separating inner cylinder 8 and connected together; the outer ring of the annular plate 10 is dimensioned to fit the inner wall of the outer separator cylinder 2 and is joined together. A plurality of smoke exhaust openings 9 are distributed on the wall of the separation inner cylinder 8, and the smoke exhaust openings 9 penetrate through the wall of the separation inner cylinder 8. Because the diameter of the outer cylinder of the separating inner cylinder 8 is smaller than that of the inner cylinder of the separating outer cylinder 2, an annular cavity is formed between the separating inner cylinder 8 and the separating outer cylinder 2, and the formed annular cavity is filled with the steel wire filling net 3.
