Custom Candle Filter System Launched to Solve Urban Pyrolysis Water Purification Challenges

——Precisely Adapting to Low-Impurity Working Conditions, Balancing Efficient Filtration and Cost OptimizationRecently, our company has launched a custom candle filter system for urban pyrolysis water treatment scenarios. With its high-precision filtration capability, standardized manufacturing process and innovative cost control solution, it has successfully solved the purification challenge of pyrolysis water containing tar and soot, providing an efficient and energy-saving solid-liquid separation solution for the environmental protection field.

Focusing on Core Needs, Precisely Matching Technical Parameters

Designed specifically for urban pyrolysis water filtration, the system accurately meets the following key working conditions: the processing flow rate meets customer requirements, it can efficiently remove tar-containing pyrolysis soot impurities, and the filtration precision reaches 2μm, exceeding the customer’s initial requirement of 3μm. The equipment adopts a 316 stainless steel cylinder with built-in titanium rod filter elements. Through optimized filtration area design, it not only meets the maximum flow rate demand but also controls the equipment footprint within the range required by the customer (height adjustable), solving the installation problem in compact spaces.

Titanium Rod Core Technology, Reshaping the Benchmark for Filtration Efficiency

The system adopts sintered titanium rod filter elements as the core filtration component. Relying on the excellent chemical stability and mechanical strength of titanium material, it achieves multiple technological breakthroughs: it can reach high-precision filtration without matching filter cloth, with a retention rate of over 99% for tar and soot in pyrolysis water; the high temperature and corrosion resistance of titanium material adapts to the complex medium environment of pyrolysis water, and the service life of the filter element is more than 3 times longer than that of traditional materials; the 35%-45% high porosity design ensures low flow resistance operation, maintaining stable pressure difference even under large flow rates and avoiding frequent shutdowns for maintenance.

The innovative pre-coating filtration process further enhances the system’s applicability: through the diatomite slurry preparation skid provided by the customer, a uniform filter aid layer is formed on the surface of the filter element, which not only maintains the porosity of the filter cake to extend the filtration cycle but also solves the filtration efficiency problem under low-impurity working conditions. The entire filtration process realizes closed-loop operation: pre-coating → filtration → forward blowing for liquid discharge → reverse blowing for slag removal → cleaning with clear liquid. It only requires one regeneration treatment per day, and the filter residue can be directly discharged into the sewage system, simplifying the operation and maintenance process.

Cost Optimization Solution, Balancing Performance and Economy

Targeting the low impurity content of the customer’s pyrolysis water, our company innovatively adopts the “core function automation + cost control optimization” solution: it retains the core function of automatic pre-coating loading and unloading to meet customer requirements; at the same time, through accurate calculation of the filtration cycle, it is recommended to omit the high-cost full-automatic control system, reducing the equipment purchase cost by more than 40% without affecting the core filtration performance.

“The core design concept of this system is ‘precision adaptation’ — it not only meets the customer’s standard requirements but also fits the cost needs of the customer’s actual working conditions,” said the technical director. “The long service life of titanium rod filter elements and the optimized filtration area design can reduce the customer’s annual operation and maintenance costs by 60%, and the initial investment can be recovered within 12 months after the equipment is put into use.”

At present, the custom candle filter system is being produced in accordance with the drawings approved by the customer. In the future, our company will continue to focus on the special working condition needs in the environmental protection field and provide more filtration solutions with both technological advancement and economic practicality.
