Problems solved by technology
This liquid drainage structure can play a role in draining liquid, but because the nozzle of the connecting pipe is generally higher than the end face of the upper tube plate, there will still be a small amount of liquid that cannot be discharged in time, which will corrode the connecting pipe, the upper tube plate, etc., if it is high-temperature corrosive Liquid, more corrosive, shortens the service life of the three-effect evaporator

The invention discloses a triple-effect evaporator liquid discharge structure. The triple-effect evaporator liquid discharge structure is arranged on the upper tube plate of a triple-effect evaporator; the triple-effect evaporator comprises an upper end closure, a heat exchange tube, a cylinder, a lower tube plate and a lower end closure; and the liquid discharge structure comprises a flange and an adapter; one end of the adapter is connected with the flange outside the cylinder, the other end of the adapter penetrates through the wall of the cylinder and the upper tube plate, and is connected with the cavity of the upper tube plate, and the opening of the adapter is lower than the upper end surface of the upper tube plate. The triple-effect evaporator liquid discharge structure can timely discharge a liquid on the upper end surface of the upper tube plate, avoids the corrosion of the triple-effect evaporator due to liquid residual, and prolongs the service life of the triple-effect evaporator.
Description
technical field [0001] The invention relates to a device liquid discharge structure, in particular to a liquid discharge structure of a three-effect evaporator. Background technique [0002] The three-effect evaporator includes an upper head, an upper tube sheet, a heat exchange tube, a cylinder body, a lower tube sheet and a lower head, and a liquid discharge structure is arranged on the upper tube sheet. The existing technology includes flanges and connecting pipes. One end of the connecting pipe is connected to the flange outside the cylinder, and the other end passes through the cylinder wall and the upper tube plate to connect with the cavity of the upper tube plate. The connecting pipe and the upper tube plate are usually welded. , The nozzle of the nozzle is generally higher than the end face of the upper tube plate, so that the nozzle and the upper tube plate can be welded. This liquid drainage structure can play a role in draining liquid, but because the nozzle of ...
