@How can intaglio printing and coating enterprises do a good job in VOCs governance? The official suggests this
Recently, the Shunde Branch of Foshan Ecological Environment Bureau released a letter to volatile organic compound enterprises in the entire region (hereinafter referred to as the "Letter").
The Letter mentioned that intaglio printing and coating industries using highly volatile raw and auxiliary materials are key VOCs emission industries, which need to be standardized. It is recommended that enterprises carefully choose governance technologies and engineering units, and should use mature, reliable, and low-cost design solutions and engineering units with more mature operational experience through multiple comparisons.
After the preliminary in-depth investigation of the Municipal Bureau of Ecological Environment, taking into account the treatment effect, equipment input, operating costs, etc., combined with the emission characteristics of intaglio printing and coating industry, the low concentration and large air volume waste gas (commonly known as ambient air, workshop waste gas) should be absorbed by zeolite runner+high-temperature incineration (TO/RTO, etc.); For medium and high concentration and wind volume waste gas such as intaglio printing drying, it is advisable to use wind reduction and concentration increase+high temperature incineration (TO/RTO, etc.), and the intaglio printing industry recommends waste heat recovery. According to the preliminary comparison and selection of VOCs governance experts, the use of the above process has a lower overall operating cost, and it is expected to recover the initial equipment investment within four to five years under the premise of complete collection, reasonable design, and standardized operation. Shunde has relevant mature cases.
Do not use technical solutions that are immature, have no actual use cases, or have unclear technical routes (including those that conceal technical routes based on patented technology), unclear operating costs, or engineering units that can only provide cases unrelated to industry governance.
The letter also mentions the need to incorporate exhaust gas treatment facilities into enterprise safety production management, conduct safety risk assessments of treatment facilities, hire safety experts or entrust safety technical service institutions to conduct safety risk assessments of treatment facilities, and improve risk control measures based on evaluation opinions, strengthening safety production work management.
