A shell and tube heat exchanger

Abstract

The invention provides a shell-and-tube heat exchanger, which relates to the technical field of heat exchangers. The shell-and-tube heat exchanger includes a heat exchanger shell, two sides of the bottom of the heat exchanger shell are fixedly connected with support mechanisms, and both ends of the heat exchanger shell are fixedly connected with water inlets respectively The center of the two ends of the heat exchanger shell is fixedly connected with a positioning mechanism, and the top and bottom of the center of the heat exchanger shell are respectively installed with a plurality of groups of straight-through heat exchange tubes and spiral heat exchange tubes. The center of the heat exchanger shell is fixedly connected with a separation mechanism corresponding to a plurality of groups of straight-through heat exchange tubes and spiral heat exchange tubes; one side of the bottom of the heat exchanger shell is fixedly connected with a water inlet pipe. By designing a simple support mechanism, positioning mechanism, water inlet module, water outlet module and separation mechanism, different heat exchanges can be performed according to actual needs. It is worth promoting vigorously.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a shell-and-tube heat exchanger. Background technique [0002] A heat exchanger is a heat exchanger energy-saving device that realizes heat transfer between materials between two or more fluids at different temperatures. The temperature reaches the index specified in the process to meet the needs of the process conditions, and is also one of the main equipment to improve energy utilization. The heat exchanger industry involves nearly 30 kinds of HVAC, pressure vessels, reclaimed water treatment equipment, chemical industry, petroleum, etc The domestic heat exchanger industry has made remarkable achievements in the research of energy saving, efficiency improvement, heat transfer efficiency improvement, heat transfer area reduction, pressure drop reduction, and device thermal strength improvement. Based on petroleum, chemical, electric power , metallurgy, shipbuilding, mac...
