A Horizontal Tube Bundle Condenser with Inclined Wire Mesh Drain Tubes

Abstract

The utility model relates to a horizontal tube bundle condenser in which wire mesh drainage tubes are obliquely inserted. In the present invention, a support plate is provided in the casing, and a horizontal tube bundle is fixed through the support plate, and a toothed hook assembly is arranged on the periphery of the horizontal tube bundle. The present invention uses the toothed hook assembly to fix the wire mesh drainage tube, and uses The pores on the surface collect the condensate on the surface of each tube row in the horizontal tube bundle, and drain it to the lower peripheral part of the horizontal tube bundle, so as to reduce the condensate on the surface of each tube row in the horizontal tube bundle. Therefore, the present invention can strengthen the condensation heat transfer of the horizontal tube bundle by reducing the thickness of the liquid film formed by the condensate on the horizontal tube bundle, so as to improve the condensation heat transfer coefficient of the horizontal tube bundle condenser.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a horizontal tube bundle condenser with obliquely inserted wire mesh drainage tubes. Background technique [0002] Horizontal shell and tube condensers are the most common type of condenser used in industrial processes. In a traditional horizontal shell-and-tube condenser, the condensed liquid on the upper row of tubes flows to the lower row step by step, and the thickness of the liquid film on the lower row of tubes will gradually increase due to the gradual accumulation of the condensed liquid film covering the lower row of heat transfer tubes. thicker, the thermal resistance increases, resulting in a decrease in the condensation heat transfer coefficient, which seriously affects the performance of heat exchangers such as condensers and feed water heaters. In the existing horizontal shell-and-tube condenser, it is difficult to really improve the condensation he...

Problems solved by technology

In a traditional horizontal shell-and-tube condenser, the condensed liquid on the upper row of tubes flows to the lower row step by step, and the thickness of the liquid film on the lower row of tubes will gradually increase due to the gradual accumulation of the condensed liquid film covering the lower row of heat transfer tubes. thicker, the thermal resistance increases, resulting in a decrease in the condensation heat transfer coefficient, which seriously affects the performance of heat exchangers such as condensers and feed water heaters

In the existing horizontal shell-and-tube condenser, even if the enhanced heat transfer tube is used, it is difficult to really improve the condensation heat transfer coefficient

This is because the enhanced heat transfer tube can only enhance the heat transfer coefficient of a single tube, but for the application scenario of a horizontal shell-and-tube condenser with a large number of tube rows in the vertical direction, the tubes above the horizontal shell-and-tube condenser Under the influence of accumulated condensate, the heat transfer coefficient of the lower tubes will still be greatly reduced
