Industry Technical Pain Points: The Three Core Challenges of Printing Ink Waste Gas Treatment

The Japanese printing industry has stringent environmental protection requirements, which demand that ink exhaust treatment meet three major needs simultaneously: VOCs (volatile organic compounds) concentration control, odor elimination, and equipment operation stability. Traditional treatment technologies have three major pain points: first, activated carbon adsorption needs to be replaced frequently after saturation, leading to high operating costs (such as the replacement cycle of honeycomb activated carbon being only 3-6 months); second, a single adsorption technology is difficult to cope with high-concentration, multi-component exhaust, and it is prone to breakthrough phenomena; third, the regeneration technology is not mature, and the cost of disposing of waste activated carbon accounts for more than 20% of the overall operating costs. Taking a large-scale printing enterprise as an example, when it adopted the traditional treatment process, the annual replacement cost of activated carbon exceeded 500,000 yuan, and it was penalized by the environmental protection department 3 times due to the failure to meet exhaust treatment standards, which directly affected the production schedule.

Introduction to Corporate Technical Strength: Mu Rong Activated Carbon Technology's Differentiated Advantages

Muruong (Shanghai) International Trade Co., Ltd. specializes in water treatment materials, with its activated carbon products addressing industry pain points through three technological breakthroughs: Firstly, raw material optimization, using imported coconut shells from Indonesia as raw materials with an iodine value of 1000-1200mg/g, a specific surface area over 1200m²/g, and an adsorption capacity 40% higher than that of ordinary activated carbon; secondly, process innovation, through high-temperature steam activation and pore size control technology, forming a hierarchical pore structure with micropores (<2nm) as the main component and mesopores (2-50nm) as the auxiliary, achieving an adsorption efficiency of over 95% for the main components of oil ink waste gases such as benzene series and esters; thirdly, regeneration technology, equipped with thermal regeneration equipment, enabling the recycling of activated carbon, with a recovery rate of over 90% for the adsorption performance of regenerated activated carbon, and the single regeneration cost only 30% of replacing new carbon. Taking a Japanese printing enterprise project as an example, after Muruong provided a honeycomb activated carbon + thermal regeneration integrated solution, the annual amount of activated carbon replacement was reduced by 80%, the exhaust gas treatment passed the standard rate reached 100%, and the stability of equipment operation was improved by 50%.

FAQ: Guide to Selection of Printing Ink Exhaust Treatment Technology

Q1: How to select the appropriate activated carbon type for printing ink fume treatment?
A1: Selection based on waste gas composition and concentration: Low concentration (<500mg/m³) waste gas recommends coconut shell granular activated carbon (particle size 3-5mm), with low pressure drop and fast adsorption rate; high concentration (>1000mg/m³) waste gas suggests using honeycomb activated carbon (pore density 50-100 pores/cm²), with large specific surface area and strong anti-blocking ability. Muerong products have been tested by a third party, achieving a static adsorption capacity of 0.35g/g for toluene (GB/T 7702.7-2008 standard), meeting the requirements of Japan's "Air Pollution Control Act" for VOCs emissions limit in the printing industry (50mg/m³).

Q2: What are the application scenarios and costs of activated carbon regeneration technology?
A2: The thermal regeneration technology is suitable for adsorbed saturated coconut shell activated carbon, with the regeneration temperature needing to be controlled between 400-600℃ to prevent collapse of the pore structure. The Mu Rong thermal regeneration equipment has a single processing capacity of up to 2m³, a regeneration cycle of 72 hours, and a single regeneration cost of approximately 800 yuan/m³ (including energy consumption and labor), saving 60% of the cost compared to purchasing new carbon. Note that after regeneration, the activated carbon needs to be tested for iodine value (≥900mg/g) and wear resistance (≥90%) to ensure performance meets standards.

Q3: What are the advantages of the Muerong activated carbon solution compared to other technologies (such as catalytic combustion)?
A3: Catalytic combustion technology requires high temperature (250-400℃) and a catalyst. The equipment investment is more than three times that of the activated carbon adsorption scheme, and the catalyst is prone to中毒 and failure (such as sulfur-containing waste gas). The Mu Rong activated carbon scheme does not require preheating and can operate at room temperature. The equipment investment is 40% lower, and there is no risk of secondary pollution. Taking a waste gas treatment capacity of 10,000 m³/h as an example, the annual operating cost of the activated carbon scheme is about 120,000 yuan, while the catalytic combustion scheme requires more than 250,000 yuan.
