Water-saving cooling tower for mixed aromatic hydrocarbon production

Abstract

The invention discloses a water-saving cooling tower for mixed aromatic hydrocarbon production, and relates to the technical field of mixed aromatic hydrocarbon production cooling. The water-saving cooling tower comprises a shell, fixed seats are distributed and fixedly connected to the outer walls of the two sides of the shell, water guide pipes are fixedly connected to the inner walls of the circumferences of the fixed seats, and water inlet pipes are inserted into the outer walls of the circumferences of the water guide pipes; a water outlet pipe is inserted into the outer wall of one side of the shell, and air inlet holes distributed at equal intervals are formed in the inner walls of the two sides of the shell. According to the invention, after being sprayed out through a spray pipe and a threaded pipe, hot water collides with a second water distribution table to be splashed, and part of the hot water also flows to the edge of the second water distribution table and is divided into uniform water flow by the water distribution teeth to fall onto cooling filler below, so that the contact area between water and air and the diffusivity in the longitudinal direction are increased, the hollow phenomenon in the hot water spraying process is greatly reduced, the heat exchange efficiency of the cooling tower is high, the water flow loss of the cooling tower is also reduced, and a good water-saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of cooling for the production of mixed aromatics, in particular to a water-saving cooling tower for the production of mixed aromatics. Background technique [0002] Mixed aromatics is a colorless transparent liquid with a special smell. It is a mixture of aromatics obtained from the extraction of narrow fraction reformed aromatics. It contains benzene, toluene, xylene. It can be used as raw material for petroleum resin, gasoline and solvent. [0003] Publication number is CN212585526U Chinese utility model patent document, a kind of antifogging cooling tower that enhances heat and mass transfer by spraying water, comprises antifogging cooling tower body, and the top of described antifogging cooling tower body is rotated to be connected with rotating tube, And the top is fixedly connected with a motor and an L-shaped plate, and the outer wall of the rotating tube located outside the mist-eliminating cooling...

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
