Under the global trend of green development, the low-carbon transformation of the sewage treatment industry is urgently needed. As a pioneer in the field of sewage treatment equipment, Techase has long regarded "promoting low-carbon sludge treatment" as an important research and development direction, and the application of carbon fiber reinforced composite (CFRP) rings is the key lever to achieve this goal.
01. How does CFRP help reduce carbon emissions in sludge treatment?
The core value of CFRP in reducing carbon emissions in the wastewater treatment industry stems from its "light and strong" characteristics. Reducing the weight of equipment components means lower energy consumption, which in turn reduces carbon emissions. CFRP, with its unique advantages of "light weight, high strength, and good toughness", has brought significant energy-saving effects to the core components of dehydrators.
Taking the example of the Stacking Screw Machine 451, the traditional Stacking Screw Dehydrator uses stainless steel rings with a single set weight exceeding 660kg, while CFRP rings of the same specification weigh only about 160kg, with a weight reduction of 75%. This change directly reduces the kinetic energy consumption during equipment operation. Tests have shown that the screw stacking machine equipped with CFRP rings reduces operating power by more than 35% compared to traditional models. Calculated based on one device running for 16 hours per day, it can reduce electricity consumption by about 12000 kWh per year, equivalent to reducing CO ₂ emissions by 9.6 tons.
02. Not only energy-saving, but also the "longevity treasure" of equipment
In addition to the energy consumption advantage brought by lightweight, the "corrosion resistance, wear resistance, and metal fatigue free" characteristics of CFRP ring sheets have solved the pain points of traditional equipment. Stainless steel rings often need to be replaced after 1-2 years due to the acid-base erosion and particle friction of sludge, which not only increases costs but also affects treatment efficiency; The deformation of the ring caused by metal fatigue can also lead to an increase in the moisture content of the sludge.
CFRP rings perfectly avoid these problems. In a project in a chemical industrial park in Zhejiang, the CFRP ring has been running continuously for 3 years, with no obvious corrosion or wear on the surface, and the equipment treatment efficiency has remained stable; The stainless steel rings used during the same period have been replaced twice. This not only extends the service life of the equipment, but also significantly reduces maintenance costs, significantly extending the "health cycle" of the equipment.
03. How wide is the application boundary? A detailed scene can be seen in the real chapter
The potential of CFRP rings goes far beyond conventional sludge treatment. In some special and harsh scenarios, its advantages are even more prominent.
Taking desulfurization wastewater treatment as an example, the sludge in such projects often has a high chloride ion content and is highly corrosive to equipment. Even if stainless steel 2205 or 2507 rings are used, severe corrosion may occur in the short term in this environment, making it impossible to continue using. However, the dewatering machine using CFRP rings has been operating stably for over 5 years in a certain power plant, and the equipment is in good working condition. According to this performance, a device in such scenarios can save the enterprise more than 150000 yuan in annual costs simply by reducing the replacement of rings and maintaining stable operation.
04. Breakthrough and common progress: make CFRP more "awesome" in the sludge battlefield
Techase is conducting in-depth cooperation with research institutions. We continuously collect application data of CFRP (carbon fiber reinforced composite material) rings and feedback on different sludge scenarios in actual projects, and accurately optimize material formulations and production processes. In the first half of this year, with the joint efforts of Techase and its partners, the wear resistance of CFRP rings has been further improved by 20%. This closely integrated collaborative model of "industry university research application" not only promotes the performance of CFRP rings to achieve a step like leap, but also helps to continuously expand their application scenarios.
In the future, Techase will continue to deepen the research and application promotion of CFRP ring technology, work together with industry partners to make this high-quality material play its value in more sludge treatment scenarios, promote the development of the sewage treatment industry towards lower carbon, more efficient, and more stable directions, and contribute greater strength to the protection of green mountains and rivers.
