Problems solved by technology

However, in actual engineering applications, the flow rate on the shell side is often limited, resulting in a decrease in the heat transfer capacity of the heat exchanger, which cannot meet the demand. The ground area should not be too large, and the bare tube bundle spiral baffle heat exchanger is difficult to meet the requirements

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] see figure 1 , the present invention includes a shell 1 and a front tube box 6 and a rear tube box 14 arranged on both sides of the shell 1, and a front tube plate 9 and a rear tube plate 9 are respectively arranged between the front tube box 6, the rear tube box 14 and the shell 1. Tube plate 15, the front tube plate 9 and the rear tube plate 15 divide the front tube box 6, the shell 1 and the rear tube box 14 into three cavities, a tube box partition 7 is arranged in the front tube box 6, The upper and lower sides of the box partition 7 are respectively provided with a pipe side outlet 5 and a pipe side inlet 8, and the upper and lower sides of the shell 1 are respectively provided with a shell side outlet 4 and a shell side inlet 12. The rear tube box 14 is provided with a cyrocyte-type enhanced heat exchange tube bundle 2, and the two ends of the ...

Abstract

The invention discloses a spiral traverse baffle supporting dimple tube bundle heat exchanger which comprises: a front tube case and a back tube case which are arranged at two sides of a shell, a tube case clapboard which is arranged in the front tube case, a tube side inlet and a tube side outlet which are respectively arranged at the upper side and the lower side of the tube case clapboard, a shell side inlet and a shell side outlet which are respectively arrange at the upper side and the lower side of the shell, a dimpled surface enhancing heat exchange tube bundle which is arranged in the shell, has two ends respectively fixed on a front tube plate and a back tube plate and communicated with a tube side inlet and a tube side outlet which are arranged on the front tube case, and is also provided with a plurality groups of spiral traverse baffles. The heat exchanger shell sides adopts the dimpled surface enhancing heat exchange tube, the turbulivity of the shell sides fluid is enhanced effectively and the shell sides heat exchange is further enhanced; the shell sides adopts the spiral traverse baffles as supporting structure, resistance loss of the shell sides is greatly reduced. The invention is characterized by high efficiency of heat exchange, small resistance loss of the shell sides flowing, compact structure, small occupied area, long service life and uneasy deposition.

Description

technical field [0001] The invention belongs to the field of heat exchange strengthening and heat exchangers, and in particular relates to a helical baffle-supported tetracystic tube bundle heat exchanger used in petrochemical, energy and power industries. Background technique [0002] Shell-and-tube heat exchangers are the most widely used heat exchange equipment in petrochemical, energy and power industries, accounting for about 37% of the world's total heat exchanger market share, and as high as 70% in the petrochemical field. The shell-and-tube heat exchanger is divided into two parts: the tube side and the shell side. Heat is exchanged through the tube wall. Baffles are set on the shell side to support the heat exchange tubes and force the fluid to change its flow mode to enhance heat transfer. The structural form of vertical bow baffles is commonly used in the industry. There are many disadvantages in this structural form, mainly as follows: (1) Due to the multiple cha...
