Integrated metal filter cartridge for high temperature dust removal and denitrification

Product features

Metal sintering dust collector is a micro-filtration element molded by nonwoven laying, overlapping and isostatic pressing the extremely fine metal fiber filaments and metal powder, and then sintered at high temperature. With the advantages of high filtration precision, good permeability, high mechanical strength, corrosion resistance and long service life, it is suitable for use at the high temperature, and widely used in high temperature dust removal in industries of cement kilns, glass kilns, ceramic kilns, chemical plant. Combined with the denitrification catalyst products developed by the company, the integrated application of dust removal and denitrification is realized.

Technical advantages and characteristics

Multiple service environment

It can be used normally and continuously below 600°C and in acid-base environment.

High performance

With high filtration precision (1-50 um), it can meet the requirement of ultra-clean emission below 5 mg/Nm3 and the dust removal efficiency is as high as 99.9%.

High denitrification efficiency

When it is used with dust collector, the denitrification rate can reach above 99%, and meet the requirement of near-zero emission.

Small resistance

It has the advantages of good permeability, low pressure loss, simple blowback and cleaning, strong regeneration capacity, simple maintenance and long service life.

High strength/machinability

It is characterized by extremely high mechanical strength and compressive strength, adjustable length, convenient processing, welding and assembly, splicing processing length of 6 m or even longer, and small floor area.

Integrated solution for high temperature dust removal and denitrification

Pollution control and comprehensive utilization of energy in the whole process of intelligent environmental protection system

By overturning the traditional process route of denitrification-dust removal - desulfurization, the system removes high temperature dust first, then treats gas pollutants and comprehensively utilizes waste heat, so that the whole environmental protection system runs under the low dust working condition, which improves the energy utilization efficiency, reduces the failure rate of environmental protection equipment, reduces the equipment volume, and greatly reduces the investment cost and floor area.

High temperature filtration and catalysis

The optimal use temperature of catalytic materials is above 300℃, while the general use temperature of traditional filter materials is not above 300℃, which limits the use of catalytic materials. The temperature range of metal filter materials perfectly solves this problem; when it is used with catalytic materials, catalytic materials can play their best performance.

Collaborative and efficient treatment process and long service life

AIREP MCF catalytic filtration system can efficiently treat PM and NOx, with a dust removal efficiency of above 99.9% and the denitrification efficiency of above 99% (the specific value varies according to specific projects). The flue gas is filtered first and then delivered to the catalyst layer for reaction, which can effectively prevent the influence of impurity ions in the dust on the service life of the catalyst, greatly prolonging the service life of the catalyst.

In addition, with strong expansibility, the catalytic filtration system can be used with other catalytic technologies to treat VOC, dioxin, CO, etc.
