Comprehensive Treatment Plan for VOCs Waste Gas of Jinjia Group

Abstract: This article introduces the VOCs exhaust gas comprehensive treatment plan providedby Wuxi ATI Group for multiple enterprises of Jinjia Group. In general, the general principle of ATI'treatment solution is: high-concentration exhaust gas and low-concentration exhaust gas separate treatment, this treatment has the best effect, the lowest cost input, and the lowest total emissions.

Shenzhen Jinjia Group Co., Ltd. ("Jinjia Group") was established in Shenzhen in 1996 and listed on the A-share SME board in 2007. The company is mainly engaged in the R&D and production of high-end packaging printing products and materials, and provides brand design and packaging solutions for well-known consumer goods enterprises. The main products are high-tech and high value-added cigarette labels, famous and special wines, high-end consumer electronics packaging and related laser film paper products.
As a green enterprise, Jinjia Group has always attached great importance to environmental governance. Since 2018, after full market research and investigation, Jinjia Group has selected Wuxi Edvance Technology Co., Ltd. (ATI Group), a pioneer enterprise in waste gas treatment, to determine the group's procurement strategic partnership. Edvance has provided a safe and reliable VOCs exhaust gas treatment system for Shenzhen Jinjia and its subordinate enterprises, including Changchun Jixing Printing Co., Ltd., Jiangsu Shuntai Packaging and Printing Technology Co., Ltd., Anhui Antai Technology Co., Ltd., Chongqing Hongsheng Industry (Group) Co., Ltd., Huzhou Xintianwai Green Package Printing Co., Ltd.
For the packaging and printing industry, Edvance adopts the general principle of treatment - separate treatment of high concentration waste gas and low concentration waste gas, which has the best treatment effect, the lowest cost input and the lowest total emissions.
Taking Shenzhen Jinjia as an example, VOCs waste gas comprehensive treatment system solutions include the following:
1. In terms of high concentration VOCs waste gas from gravure printing machines, air reduction and enrichment are implemented. The total air volume of the waste gas from two gravure printing machines after air reduction is 30000Nm ³/ h. With high concentration, RTO is directly used for incineration, and RTO can self maintain operation.
2. In order to reduce environmental odor, an additional 3000 m is reserved for gravure printing machine ³/ H Air exhaust can be turned on or off as required.

3. In terms of waste heat recycling, RT00 is equipped with a set of air-water heat exchanger to recover waste heat from waste gas. The recovered hot water is connected to ESO and finally used to heat the oven, saving energy consumption for gravure printing machine operation.
4. In terms of offset printing waste gas, in view of the large number of offset printing equipment in Shenzhen Jinjia, the total air volume of offset printing waste gas is large (125000m ³/ H) Low concentration (105ppm c3 (about 300mg/m ³)， The offset printing waste gas is treated by the combined process of "filtration"+"activated carbon adsorption"+offline desorption "+catalytic combustion".

5. In terms of screen printing waste gas, the total air volume of screen printing waste gas is relatively large (60000 m ³/ H), the concentration is about 41ppm c3 (about 117mg/m ³)， The silk screen waste gas is treated by the combined process of "filtration"+"UV photocatalysis"+activated carbon adsorption ".

6. Display of actual governance achievements
According to the monitoring report of the first quarter of 2020 published on the official website of Shenzhen Jinjia Group Co., Ltd., the actual emission of waste gas after being treated by the comprehensive treatment plan of Edvance is far less than the local standard of Guangdong Province.
The following are more cases that Edvance gave to other subsidiaries of Jinjia Group

1. Jilin Jixing case (air volume 25000m ³/ h )

2. Jiangsu Shuntai case (air volume 30000m ³/ h )

3. Chongqing Hongsheng case (air volume 25000m ³/ h )

4. Huzhou Xintianwai Case (air volume 30000m ³/ h )

5. Anhui Antai case (air volume 30000m ³/ h )
