Embodiment Construction

[0031] The following notes are provided in the embodiment of the present invention.

[0032] The inclination angle of the baffle: the angle between the plane of the baffle and the axis of the shell after the baffle rotates along its radius.

[0033] Inner weir height: the height of the edge of the partition near the center of the fan-shaped baffle;

[0034] Outer weir height: the height of the edge of the partition near the arc edge of the fan-shaped baffle.

[0035] Leakage phenomenon: There is a certain gap between adjacent baffles during the lapping process. In this way, when the fluid in the shell side flows, a part of the fluid will flow regularly along the preset baffle channels, and another part of the fluid will leak into the next area through the modified gap, resulting in the fluid passing through the heat exchange tube As the flow rate decreases, the fluid velocity becomes slower, thereby reducing the heat transfer coefficient of the heat exchanger and affecting t...

Abstract

The invention discloses a helical baffle-heat exchanger and relates to the technical field of heat exchanging. The helical baffle-heat exchanger can solve the technical problem that leakage flow phenomenon is prone to occurring in a spiral channel in the heat exchanger. A seamless spiral channel is formed in a shell of the heat exchanger and is formed by connecting at least two baffle plates, and a separation plate is connected between every two adjacent baffle plates. The helical baffle-heat exchanger can avoid occurrence of the leakage flow phenomenon in the flow process of shell pass fluid and guarantee the heat exchanging performance of the heat exchanger.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a spiral baffle heat exchanger. Background technique [0002] With the rapid development of economy and industry, countries around the world are facing the problem of energy shortage, so how to efficiently use existing energy is the focus of people's increasing attention. Among them, the heat exchanger is an energy-saving device that realizes heat transfer between materials between two or more fluids at different temperatures. It transfers heat from a higher fluid to a lower temperature fluid and improves energy utilization. One of the main equipment of the rate. At present, the widely used heat exchanger is the spiral baffle heat exchanger. The spiral baffle heat exchanger is generally composed of shell side, heat exchange tube bundle, tube sheet, baffle (baffle) and tube box and other components. . [0003] When the baffle in the shell side is a spiral baffle, the fl...
