Waste heat recovery dryer: Working principle of waste heat recovery dryer

Because the heat recovery dryer has a long micro-heating cycle, it greatly reduces the energy consumption of the micro-heat adsorption dryer. The micro-heat adsorption dryer consumes less regeneration gas, and the air compressor consumes less energy. From the perspective of comprehensive energy consumption, the micro-heat adsorption dryer has great advantages in the field of compressed air purification.

What are the effects of excessively high inlet air temperature in an adsorption dryer?

Generally, dryer manufacturers will specify in the instruction manual that the inlet air temperature of an adsorption dryer should not be too high, generally controlled below 40℃. If the inlet air temperature of the dryer is too high, it will cause the desiccant in the dryer to fail, affecting the dew point temperature (i.e., dryness) of the compressed air. Although adsorption dryer manufacturers emphasize that the dryer inlet air temperature should not be too high, many users do not pay enough attention, resulting in dryer inlet air temperatures as high as 100℃ or more.

Adsorption dryer: How to replace the desiccant in an adsorption dryer?

VOCs catalytic combustion system for organic waste gas

VOCs organic waste gas catalytic combustion system and CO catalytic combustion equipment processing technology is very practical, with high requirements for waste heat recovery and reuse; there is no other full process that can be used as a heat exchanger purchase process; it is suitable for the same production line because different products often have varying waste gas compositions or very rough waste gas concentration values. It cleans and processes high-concentration organic chemical waste gases formed in the production industry, including crude oil, chemical plants, vulcanized rubber, paint, spraying, furniture, printing iron barrels, packaging and printing, etc. The types of organic chemicals that can be processed include benzene, macrolides, esters, phenolic compounds, hydrocarbons, aldehydes, ethers, and more.

How to deal with the waste gas from printing plants

1. Overview of Printing Waste Gas The printing industry produces organic waste gas during printing, drying, and cleaning processes. This is mainly due to the use of printing inks, especially during the printing drying process, where evaporation produces a large amount of organic waste gas. Organic solvents account for 70%-80% of the total amount of organic ink. The main components of printing waste gas are benzene, toluene, xylene, acetone, butanone, lipids, ethers and other organic waste gases, which not only affect the health of employees, but also cause air pollution to the surrounding environment. Therefore, it is necessary to purify printing waste gas to meet emission standards.
