Heat exchanger structure having functions of dust removal and liquid separation

Abstract

The invention discloses a heat exchanger structure having functions of dust removal and liquid separation. A cold medium outlet communicates with cold medium outlet space, a cold medium inlet communicates with cold medium inlet space, and a U-shaped heat exchange tube is arranged in a heat exchanger shell, wherein an inlet of the U-shaped heat exchange tube communicates with the cold medium inletspace, and an outlet of the U-shaped heat exchange tube communicates with the cold medium outlet space; a heat medium inlet is formed in the side of the top of the heat exchanger shell, the top of a Y-shaped diversion downcomer communicates with the bottom outlet of the heat exchanger shell , the lower end of the Y-shaped diversion downcomer is inserted into a liquid collection tank, a demister isarranged between the inner wall of the liquid collection tank and the outer wall of the Y-shaped diversion downcomer, and a heat medium outlet is formed in the side of the top of the liquid collection tank. The heat exchanger structure can realize the functions of dust removal, liquid separation and heat exchange.

Description

technical field [0001] The invention belongs to the technical field of energy and chemical industry, and relates to a heat exchanger structure with dust removal and liquid separation functions. Background technique [0002] Heat exchanger is a common and very important equipment in production, mainly concentrated in petroleum, chemical industry, metallurgy, electric power, shipbuilding, central heating, refrigeration and air conditioning, machinery, food, pharmaceutical and other fields. 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 index is to meet the needs of the process conditions, and it is also one of the main equipment to improve energy utilization. [0003] There are many structural forms of heat exchangers, but convention...

AI Technical Summary

Problems solved by technology

[0003] There are many structural forms of heat exchangers, but conventional heat exchangers only have the function of heat exchange. For the heat medium, after the liquid phase is precipitated after the gas phase cools down, in order to prevent the downstream system from being affected by the liquid, it is usually reinstalled. A water separator to separate condensed water

In addition, conventional heat exchangers do not have the function of dust removal. For some high-temperature solid-containing gas phases, dust collectors need to be installed before entering the downstream system, which increases the number of equipment and investment, making the process longer and more leakage points
