(1) Definition of VOCs
According to the WHO definition, volatile organic compounds (VOC) refer to various organic compounds with a boiling point of 50℃-260℃ at normal temperature. According to its chemical structure, VOC can be further divided into: alkane, aromatic hydrocarbon, ester, aldehyde and others. More than 300 have been identified.
Emissions of volatile organic compounds (VOCs) involve petrochemical, chemical, spraying, furniture manufacturing, printing, and shoemaking industries. VOCs emissions not only cause air pollution and endanger human health, but also cause serious waste. Therefore, the recovery and purification of organic waste gas is an inevitable trend for sustainable development of enterprises.
(2) Description of product
VOCs organic waste gas treatment equipment (device) is composed of adsorption tank (tower), high-efficiency dedicated activated carbon adsorbent, desorption recovery, fan and other parts. Through the strong adsorption effect of high-efficiency dedicated activated carbon adsorbent, organic waste substances are adsorbed into the pores of activated carbon .
The product can adsorb the exhaust gas of organic solvents such as benzene, alcohol, ketone, ester, gasoline, etc., and is more suitable for the treatment of organic exhaust gas with large air volume and low concentration. It can effectively purify the environment, eliminate pollution, improve working conditions, ensure the health of workers, recover organic solvents and reduce production costs. The equipment (device) is a new series of products with high efficiency, energy saving and no secondary pollution. The product runs stably, safely and has low comprehensive operating cost and the product reaches the advanced level of similar products.
The high-efficiency dedicated activated carbon adsorbent in this device is a new technology product with related intellectual property rights of our company. It has the characteristics of high strength, large VOCs adsorption capacity, developed mesopores, easy desorption and regeneration .For the adsorption of aldehydes and ethers, special activated carbon catalysts are used.
(3) Performance characteristics
1). the equipment (device) has advanced technology. According to the actual working conditions, design the device specifications and the amount of adsorbent loading. Therefore, the device has fast adsorption rate, large adsorption capacity, and purification efficiency of more than 98%.
2). Good safety. Systematic explosion-proof design and safety node monitoring, strict product quality assurance system to ensure the equipment safety and meet the demanding requirements of chemical production factory.
