Bulannuo Industrial Packaging Materials (Shanghai) Co., Ltd. is a foreign-funded enterprise that develops, produces and sells environment-friendly metal surface treatment and anti-rust materials, industrial packaging paper products, plastic film, plastic packing boxes and containers, etc.
The main pollutants monitored by the company are exhaust gases from the printing shop, including total non-methane hydrocarbons, temperature, pressure, flow rate and humidity. On-line monitoring system for the LH - 1900 volatile organic compounds, the system USES the Internet of things technology, wireless communication technology, the VOCs, 24 hour omni-directional monitoring system to realize the fixed source monitoring and statistics and analysis of volatile organic gas, quickly adapt to the business requirements and data fusion, achieve closed-loop operation monitoring, governance, monitoring, management, integration of operations, Provide real VOCs data for environmental protection departments

Ningxia Hongde Packaging Materials Co., Ltd. is a printing enterprise with an annual output of 400,000 large boxes of tobacco packaging materials. The waste gas components in the production process are n-propanol, ethanol, ink solvent volatiles and so on. The organized treatment capacity is 50,000 nm3 /h, the concentration of waste gas is less than 600mg/m3, and the unorganized waste gas is less than 100mg/m3. The process of "zeolite wheel + rotary RTO/UV photolysis + activated carbon" is adopted.

The waste gas produced by Hengjie wood is 150,000 m3/h, and the organic content is not high. In view of the large air volume and low concentration of organic waste gas, the company uses - "three stage filtration + concentration wheel + regenerative incineration (RTO)" technology, effectively solve this problem! The exhaust gas of the workshop is collected through the pipeline for dust removal and filtration, and then discharged to the standard after adsorption by the runner.
