Plate gas-to-gas heat exchanger

2021-04-02View Original

Thread Content

A high-efficiency plate-type gas-to-gas heat exchanger is a heat exchange device used for energy recovery. Two counterflowing air streams are separated by an ultra-thin heat transfer plate, and heat exchange occurs due to the temperature difference, thereby enabling energy recovery. 1. Features: This gas-to-gas heat exchanger uses corrosion-resistant, ultra-thin elements as heat transfer conductors and is manufactured through enhanced stamping and burring techniques. It boasts advantages such as high strength, excellent sealing (air leakage rate below 1%), fast heat transfer, high recovery efficiency (recovery rate up to 70%), easy maintenance, and a long service life. Additionally, it utilizes air at ambient temperature for heat exchange, eliminating the need for additional energy consumption. Furthermore, the monomers can be modularly arranged in various combinations to suit different heat exchange conditions. 2. Cleaning can be done using tap water or a neutral cleaning solution; it is convenient to use and requires simple maintenance. 3. Plate-type gas-to-gas heat exchangers are mainly used for the recovery of waste heat from clean flue gases and for color removal. Waste heat recovery: Heat recovery from exhaust gases in drying ovens and drying equipment ; Biological processors, heat recovery for waste gases in the fermentation industry ; Other industrial heat recovery systems. Flue gas whitening: Rapid whitening of clean flue gas/water mist in natural gas boilers, food factories, tofu factories, starch factories, etc

Efficiency is always at the expense of resistance. If you require low resistance, for example

The air resistance is too high; it’s not suitable for use on chimneys to recover heat
Reply #42021-04-06
Yes, it has been applied in flue gas whitening for natural gas boilers and heat recovery in biological treatment units

This pressure loss is generally around 100–200 Pa

What is the shape of the heat exchanger plates, and what is the spacing between them? Is it a fully welded heat exchanger? The diagram shows how much flow there is in each of the two air streams in the heat exchanger; generally, the volume of air isn’t very large, right?
