AI Technical Summary

Technical Problem

The existing combined serpentine fin tube condenser has a large structure width, occupies a lot of space, has high transportation costs, and has poor heat transfer performance and serious low-temperature dew point corrosion problems when recovering low-temperature waste heat, which limits the promotion and use of low-temperature heat exchangers.

Method used

An integrated combined condenser was designed, which adopts U-shaped connected pressure condensation section and normal pressure condensation section, combined with the staggered arrangement of straight fin tubes and serpentine fin tubes to enhance heat transfer capacity. An insulation layer is set in the shell to prevent corrosion, and medium-frequency electric heating and argon arc welding are used to simplify the manufacturing process.

Benefits of technology

It achieves efficient, energy-saving and environmentally friendly waste heat recovery, reduces manufacturing costs and labor intensity, improves heat exchange efficiency, reduces direct emissions of harmful gases, and extends equipment service life.

Abstract

The utility model discloses an integrated combined condenser which comprises a shell, the interior of the shell is divided into a pressure-bearing condensation section and a normal-pressure condensation section through a partition plate, the bottom of the pressure-bearing condensation section is communicated with the bottom of the normal-pressure condensation section, a smoke inlet is formed in the upper side of the pressure-bearing condensation section, a smoke outlet is formed in the top of the normal-pressure condensation section, and a plurality of rows of straight finned tubes are distributed in the pressure-bearing condensation section in parallel. The straight finned tubes in the bottommost row are communicated with a water inlet header of the pressure-bearing condenser, the straight finned tubes in the uppermost row are communicated with a water outlet header of the pressure-bearing condenser, the straight finned tubes in the adjacent rows are arranged in a staggered mode, and the ends of the straight finned tubes in the adjacent rows are communicated pairwise through headers. The snakelike finned tubes located at the bottommost row are communicated with a water inlet collecting box of the normal-pressure condenser, and the snakelike finned tubes located at the uppermost row are communicated with a water outlet collecting box of the normal-pressure condenser. The integrated combined condenser has the advantages of being high in heat efficiency, low in smoke exhaust temperature, compact in structure, long in service life, attractive in appearance, efficient, energy-saving and environment-friendly.
