Efficient drain water recovery box

Abstract

The invention relates to an efficient drain water recovery box which comprises a cylindrical box body, spraying pipes, vapor condensation fins and an exhaust port. The cylindrical box body is a vertical thin-wall cylinder. The multiple spraying pipes are arranged in a criss-cross manner and are horizontally arranged in the cylindrical box body, and spraying holes which are evenly distributed are formed in the spraying pipes. The vapor condensation fins are arranged in the cylindrical box body and located below the spraying pipes and comprise the multiple condensation fins which are arranged in parallel. The condensation fins are hollow platy pipes which are horizontally arranged and are filled with condensate. The exhaust port is formed in the upper portion of the cylindrical box body, and a filtering net cover arranged in the cylindrical box body is further arranged at the lower end of the exhaust port. The efficient drain water recovery box has the beneficial effects that a large quantity of vapor is condensed into water immediately after making contact with the vapor condensation fins, the rest of vapor directly encounters foggy drain water sprayed down through the spraying pipes which are arranged in the criss-cross manner, the vapor is basically completely absorbed in the foggy drain water and does not move upwards any more, only an extremely-small quantity of vapor overflows and is almost negligible.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a high-efficiency hydrophobic recovery box. Background technique [0002] The drain recovery tank of the power plant is used to recover and reuse the drain of the steam turbine. Steam turbines need a lot of steam to work. Steam flows in pipelines and steam turbines will produce condensed water. Condensed water is chemically treated secondary desalinated water. Its manufacturing cost is high. If it is discharged directly to the outside, it will cause a lot of waste. Drainage The recovery box plays the role of condensed water recycling. [0003] The high-pressure steam and low-pressure steam of the steam turbine lead the drainage into the drainage recovery box through the steam traps at each drainage point, and the drainage recovery box collects all the drainage and then introduces it into the condenser, so that the drainage and the completed high-pressure and low-pressure ...

AI Technical Summary

Problems solved by technology

Due to some reasons involved in the current drainage system of steam turbines, the drainage has not completely condensed into water. The drainage China contains a large amount of steam. After the drainage and the remaining steam enter the drainage recovery box, the remaining steam leaks through the top vent of the drainage recovery box. It causes a great waste of energy, and a large amount of high-temperature steam is discharged, causing the death of surrounding plants and destroying the environment.
