Tubular heat exchanger for chemical production

Abstract

The invention discloses a tube-and-tube heat exchanger for chemical production, which includes a support column and a heat exchange tube. A base is installed below the support column, and an outer cylinder is fixed above the support column. The outer cylinder The left side of the outer cylinder is provided with a first medium inlet, and the lower left side of the outer cylinder is provided with a sewage outlet, the upper left side of the outer cylinder is provided with a first medium outlet, and the upper right side of the outer cylinder is provided with a second medium outlet. Two medium inlets, and a second medium outlet is provided on the right side of the outer cylinder, a fixed ring is fixed on the outside of the outer cylinder, spacers are installed at both ends of the heat exchange tubes, and the heat exchange tubes are located outside Inside the cylinder, a baffle device is installed in the middle of the outer cylinder. The tube-and-tube heat exchanger for chemical production has a relatively solid shell, which can flexibly adjust the flow direction of the fluid, thereby flexibly adjusting the flow speed of the fluid and the efficiency of heat exchange.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a shell and tube heat exchanger for chemical production. Background technique [0002] A heat exchanger is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the process The specified indicators meet the needs of process conditions, and it is also one of the main equipment to improve energy utilization. The heat exchanger industry involves nearly 30 industries such as HVAC, pressure vessels, reclaimed water treatment equipment, and chemical industry, forming industries with each other. chain. [0003] The shell of the existing heat exchanger is not strong enough during use, and the current flow direction of the fluid cannot be flexibly adjusted, so as to change the velocity of ...
