Project Overview
The client of this project is one of the top three coating enterprises in the world, producing and operating coatings, glass, glass fiber and chemicals. At present, we help customers from industry, transportation, consumer goods, construction and other fields and their aftermarket to improve the appearance of products in various forms.
In the process of coating production, volatile organic waste gas is produced, which affects the workshop and the environment. In order to protect the environment and meet the national and local emission standards, the customer added 5 sets of waste gas treatment equipment needs, Aier with a large number of core technologies and application cases in the field of waste gas treatment, the customer recognition, this project new equipment by Aier design, manufacturing, installation, commissioning and training services.
The Solution
RTO furnace (three chambers) : The process of filter + runner +RTO is adopted. After filtering, the waste gas enters the runner for concentration, and the concentrated waste gas enters the RTO for incineration. The RTO furnace is three-tower, with one inlet, one outlet and one purge.
Dust removal: The explosion-proof cartridge filter is adopted. After dust removal, the particulate matter is controlled below 0.5um, and then the exhaust gas is absorbed into the activated carbon box for adsorption treatment. The VOC concentration at the export reaches the emission standard.
Two activated carbon: exhaust gas into the activated carbon box, organic matter is adsorbed by activated carbon in its interior, clean gas discharge.
Aier waste gas treatment equipment has experienced many years of market verification, service more than 100 waste gas treatment projects. Provide exhaust gas solutions according to specific projects, save energy consumption and reduce operating costs under the premise of ensuring exhaust emission standards.
