Efficient exhaust steam separation device and separation method

Abstract

The invention relates to an efficient steam discharging and separating device as well as a separating method. The existing equipment adopts a pore plate form if the steam discharging quantity is small, some equipment has large steam discharging quantity and some equipment has large-sized pipelines, the flash steam generated instantly is large in quantity and high in humidity when saturated steam is discharged, and a steam and water separation device which is liable to cause gas resistance to enable the equipment to be overpressure cannot be mounted. The efficient steam discharging and separating device comprises a separating outer cylinder (1); a separating inner cylinder (4) is arranged at the middle position of the internal part of the separating outer cylinder; an upper ring plate (3) and a lower ring plate (2) are welded between the separating outer cylinder and the separating inner cylinder correspondingly; an upper sealing cover (5) is welded above the separating inner cylinder;a conical drainage device (6) is welded below the separating inner cylinder; the lower ring plate is welded at the bottom of the separating outer cylinder; the conical drainage device is manufacturedby welding a conical shell and a connecting pipe; and the steam discharging and separating device is connected with a steam discharging and connecting pipe inside or outside the equipment in a weldingor flange mode. The invention is applied to the efficient steam discharging and separating device.

Description

Technical field: [0001] The invention relates to an efficient exhaust steam separation device and a separation method. Background technique: [0002] Existing equipment generally adopts the orifice plate form if the steam exhaust volume is small. For example, some equipment with a large exhaust steam volume and large pipeline specifications (such as expansion vessel equipment, etc.) will generate a large amount of flash steam instantly when the saturated steam is discharged. The humidity is high, and a steam-water separator with excessive resistance cannot be installed, which may easily cause air resistance and overpressure the equipment. Before, there was a steam-water separation device with a louver structure, but there was a situation where the blades of the louver structure were blown out of the equipment due to the excessive pressure difference between the two ends, and the structure was unsafe. The flow direction is constantly changing, so that the energy of the fluid...

Problems solved by technology

[0003] In the steam-water heat exchange equipment, the equipment needs to exhaust steam to the outside, and some equipment generally have two destinations for the external steam exhaust, one is discharged to the next-level equipment, and the other is discharged to the atmosphere, and the impact of the steam on the pipeline is discharged to the lower-level equipment If it is discharged into the next-level equipment, the exhaust steam generally needs to increase the dryness of the steam to prevent the impact of wet steam on the lower-level equipment and steam pipelines. Therefore, it is necessary to increase the dryness before transportation. Check the dryness of the steam; if it is discharged into the atmosphere, the water in the steam will also be discharged when it is discharged into the atmosphere, resulting in the loss of working fluid, resulting in loss of both energy and working fluid; for these two exhaust methods, a A simple steam-water separation device, adopting the device of the invention can effectively gather most of the liquid in the wet steam, achieve the dehumidification effect and effectively recover the working medium, and improve the economical efficiency of the equipment
