Immersed self-flow-interfering shell-and-tube-type heat exchanger

Abstract

The invention provides an immersed self-flow-interfering shell-and-tube-type heat exchanger. The heat exchanger comprises a shell, a liquid distribution device, a self-flow-interfering device and a liquid collection device; a cooling liquid inlet and a cooling liquid outlet are formed in the shell; the cooling liquid inlet communicates with the liquid distribution device; the liquid distribution device communicates with the self-flow-interfering device; the liquid collection device is located on the upper part of the shell and below the liquid surface of cooling liquid; the liquid collection device communicates with the cooling liquid outlet; the cooling liquid enters the shell sequentially through the cooling liquid inlet, the liquid distribution device and the self-flow-interfering device, and flows out of the cooling liquid outlet through the liquid collection device; a heat source is immersed in the cooling liquid in the shell; and the liquid distribution device comprises a liquiddistribution mother tube which communicates with the cooling liquid inlet. The immersed self-flow-interfering shell-and-tube-type heat exchanger is controlled through liquid outlet temperature, so that the effects of automatic controlling and energy saving are realized; the interfering strength of a cooling liquid flowing field in the shell is enhanced; and the heat exchanging efficiency is improved.

Description

technical field [0001] The invention relates to the field of shell and tube heat exchangers, in particular to a submerged shell and tube heat exchanger. 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-and-tube heat exc...
