Horizontal shell and tube type condenser with liquid guide devices

Abstract

The invention relates to a horizontal shell and tube type condenser with liquid guide devices. At present, when designing the horizontal shell and tube type condenser, people compensate the negative influence of tube bundle effect on the condensation heat exchange only by increasing the amount of heat exchange tubes so as to cause increase of the volume of heat-exchange equipment and the improvement of the production cost. The horizontal shell and tube type condenser with the liquid guide devices comprises a shell (1). Both sides of the shell are connected with a tube plate (2). A space inside the shell surrounded by the shell and the tube plate is provided with a set of heat exchange tubes (3). The heat exchange tubes are provided with support plates (4). Continuous liquid guide devices (5) are installed below the heat exchange tube and are collection liquid guide device or separation liquid guide devices. The shell is provided with an air inlet (9) and a liquid outlet (10). The invention can be widely applied in the fields of petroleum, chemical industry, metallurgy, pharmaceutical manufacturing, air conditioning, refrigeration, heat supply and the like.

Description

Technical field: [0001] The invention relates to a horizontal shell and tube condenser, in particular to a horizontal shell and tube condenser with a liquid guide. Background technique: [0002] Horizontal shell and tube condensers are widely used in petroleum, chemical industry, metallurgy, pharmaceutical, air conditioning, refrigeration and heating and other fields. The heat exchange efficiency directly affects the industrial production cost and energy utilization efficiency, so it has always been an important Research and improve objects. Since the 1970s, in order to improve the heat transfer performance of condensing heat exchangers, people have achieved a lot of fruitful results by changing the structural characteristics of the outer surface of the tube. However, these works have not solved the problem that the condensate in the upper row of tubes drips down in the horizontal shell and tube condenser, which causes the liquid film of the lower row of heat exchange tubes...

AI Technical Summary

Problems solved by technology

However, these works did not solve the problem that the condensate in the upper row of tubes in the horizontal shell-and-tube condenser drips down, which causes the liquid film of the lower row of heat exchange tubes to thicken, resulting in a decrease in the overall heat transfer performance of the tube bundle (called the tube bundle effect).

At present, when designing a horizontal shell-and-tube condenser, people can only rely on increasing the number of heat exchange tubes to compensate for the adverse effect of the tube bundle effect on condensation heat exchange, which leads to an increase in the volume of heat exchange equipment and an increase in manufacturing costs.
