Problems solved by technology

However, the heat transfer uniformity of the above-mentioned heat pipe is not enough, condensation is only carried out on one side, and the heat transfer amount is also small, so it needs to be improved and a heat pipe system with a new structure should be developed

Embodiment Construction

[0023] A shell-and-tube heat exchanger, such as figure 1 As shown, the shell-and-tube heat exchanger includes a shell 20, a heat exchange component 23, a shell side inlet connection 21 and a shell side outlet connection 22; the heat exchange component 23 is arranged in the shell 20, and the heat exchange component It is fixedly connected to the front tube sheet 16 and the rear tube sheet 19; the shell-side inlet connecting pipe 21 and the shell-side outlet connecting pipe 22 are both arranged on the shell 20; the fluid enters from the shell-side inlet connecting pipe 21 and passes through the heat exchange components. For heat exchange, take over the outlet pipe 22 on the shell side to go out.

[0024] Preferably, the heating element extends along the horizontal direction. The heat exchangers are arranged horizontally.

[0025] figure 2 A top view of the heat exchange component 23 is shown, as figure 2 As shown, the heat exchange component includes a central tube 8, a le...

Abstract

The invention provides a shell-and-tube heat exchanger. The shell-and-tube heat exchanger comprises a shell body, tube plates are arranged at the two ends of the shell body respectively, a heat exchange component is arranged in the shell body, the heat exchange component comprises a center tube, a left side tube, a right side tube and tube sets, a first outlet and a second outlet are formed in thetwo opposite sides of the center tube, and a left pipe set and a right pipe set are in mirror symmetry along a plane where the axis of the center pipe is located. According to the vibration tube bundle shell-and-tube heat exchanger with a novel structure, more tube sets are arranged in a limited space, the vibration range of a tube bundle is enlarged, and therefore heat transfer is enhanced, anddescaling is enhanced.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to a shell-and-tube heat exchanger with intermittent vibration descaling. Background technique [0002] Shell-and-tube heat exchangers are widely used in chemical, petroleum, refrigeration, nuclear energy and power industries. Due to the worldwide energy crisis, in order to reduce energy consumption, the demand for heat exchangers in industrial production is also increasing. The quality requirements for heat exchangers are also getting higher and higher. In recent decades, although compact heat exchangers (plate, plate-fin, press-welded plate heat exchangers, etc.), heat pipe heat exchangers, direct contact heat exchangers, etc. have been developed rapidly, but due to the The heat exchanger has a high degree of reliability and wide adaptability, and it still occupies a dominant position in output and consumption. According to relevant statistics, the current consumption of shell-a...
