A water-saving cooling tower for the production of mixed aromatics

Abstract

The invention discloses a water-saving cooling tower for the production of mixed aromatics, and relates to the technical field of cooling for the production of mixed aromatics. The inner wall is fixedly connected with a water guide pipe, the outer wall of the water guide pipe is plugged with a water inlet pipe, one side of the outer wall of the housing is plugged with a water outlet pipe, and the inner walls of both sides of the housing are equipped with inlet pipes distributed equidistantly. stomata. In the present invention, after the hot water is sprayed out through the nozzle pipe and the threaded pipe, it will collide with the second water distribution table and splash, and part of the hot water will flow to the edge of the second water distribution table and be divided into uniform water flows by the water dividing teeth. Falling into the cooling filler below, it increases the contact area between water and air and the diffusion degree in the longitudinal direction, greatly reduces the hollow phenomenon in the process of hot water spraying, makes the heat exchange efficiency of the cooling tower high, and also reduces the The cooling tower has a good water-saving effect on the loss of water flow.

Description

Technical field [0001] The present invention relates to the field of mixed aromatics production cooling technology, in particular to a water-saving cooling tower for mixed aromatics production. Background [0002] Mixed aromatics are colorless, transparent liquids with a special odor, narrow fraction reforming aromatics resulting from aromatic mixtures. It contains benzene, toluene, xylene. It can be used as a raw material for petroleum resins, gasoline, and solvents. [0003] Publication number cn212585526U Chinese utility model patent document, a kind of anti-fog cooling tower by spraying water to enhance heat transfer and mass transfer of the anti-fog cooling tower, including the anti-fog cooling tower body, the top of the anti-fog cooling tower body is rotated with a rotating tube, and the top is fixed with a motor and an L-type plate, the rotating tube is located on the outside of the anti-fog cooling tower body The outer wall fixed sleeve is connected with a driven gear, an...

AI Technical Summary

Problems solved by technology

It effectively solves the problem that the spray water used by the anti-fog cooling tower to enhance heat and mass transfer is usually installed with a fixed spray pipe inside the anti-mist cooling tower for spraying, but the spraying is not uniform and the spray effect is not good.

[0004] But above-mentioned invention has following weak point: when the spray pipe in this device is carrying out spraying work, the water flow that the nozzle hole ejection of spray pipe bottom can form the water distribution umbrella film, and the water flow is hollow, and the water spray thickness is uneven and other problems, so that the cooling effect of the cooling tower cannot be guaranteed. At the same time, due to the poor cooling effect of the cooling tower, it will greatly increase the water consumption of the cooling tower, which is not conducive to the recycling of water resources.
