High-efficiency energy storage type heat exchanger

Abstract

The invention discloses a high-efficiency energy storage heat exchanger, which comprises a cylindrical shell, a core tube is installed in the shell, the core tube includes two tube plates, and a tube plate arranged between the two tube plates Multi-layer tube bundle layer; the multi-layer tube bundle layer is generally in the shape of a cylinder with a gradually decreasing inner diameter, and each tube bundle layer includes a plurality of heat exchange tubes with the same structure and spirally wound sequentially around the center of the cylinder; The spiral direction of the heat exchange tubes in the two adjacent tube bundle layers is opposite; the filter device is provided on the outside of the tube plate in the direction of the fluid inlet of the heat exchange tube; Shell side fluid inlet. The heat exchange tube bundle in the core tube of the heat exchanger is small in diameter and spirally arranged, effectively increasing the heat exchange area and improving the heat exchange efficiency, and a filter device is also installed at the inlet and outlet of the tube bundle to prevent possible blockage in the fluid Impurities in the tube bundle are filtered in time to prevent impurities from clogging the tube bundle.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a high-efficiency energy storage heat exchanger. Background technique [0002] The shell-and-tube heat exchanger performs heat exchange through the heat exchange between the tube-side fluid and the shell-side fluid, and has been widely used in petroleum, chemical, light industry, electric power, steel and other industries. The shell-and-tube heat exchanger includes a shell and a heat exchange tube bundle installed inside the shell. At present, the heat exchange tube bundles used are in the form of straight tubes, but the heat exchange area of ​​the heat exchange tube bundles in this straight tube form is small and the heat exchange efficiency is low. It is not high; and using a tube bundle with a small diameter of the heat exchange tube and setting it in a spiral can effectively increase the heat exchange area and improve the heat exchange efficiency, but once the tube bundle with a small diam...

The shell-and-tube heat exchanger includes a shell and a heat exchange tube bundle installed inside the shell. At present, the heat exchange tube bundles used are in the form of straight tubes, but the heat exchange area of ​​the heat exchange tube bundles in this straight tube form is small and the heat exchange efficiency is low. It is not high; and using a tube bundle with a small diameter of the heat exchange tube and setting it in a spiral can effectively increase the heat exchange area and improve the heat exchange efficiency, but once the tube bundle with a small diameter is blocked by impurities in the fluid, it will It is difficult to clean, and it can only be replaced, which wastes manpower, material and financial resources, and even delays the progress of the project
