●Technical Parameters

●Product Introduction
Medium Temperature Dust Filter Bag are a type of filter bag designed for industrial flue gas dust removal systems with continuous working temperatures of 120℃~180℃**. Made of high-performance fibers with heat and chemical corrosion resistance, they can operate stably for a long time under medium-temperature flue gas conditions, effectively capture fine dust particles, and improve emission compliance rates.
●Common materials and performance
Brief description of continuous heat resistance characteristics of materials
Acrylic (Acrylic) 130℃ strong acid and alkali resistance, economical and practical, weak hydrolysis resistance
PPS (polyphenylene sulfide) 160℃ acid and alkali resistance, moisture and heat resistance, anti-condensation, long service life
Aramid (Nomex) 200℃ excellent heat resistance, strong wear resistance, suitable for dry high temperature environment
Composite fiber filter material 150~180℃ combines the advantages of multiple fibers to adapt to complex flue gas conditions
●Core advantages of medium temperature dust removal filter bags
1. Stable temperature resistance
It can work stably for a long time at 120~180℃ without softening or deformation, suitable for high temperature emission occasions such as incinerators and boilers.
2. Good chemical corrosion resistance
The material has good resistance to acids, alkalis, salt spray, etc., and is particularly suitable for complex working conditions such as garbage incineration and chemical exhaust.
3. Efficient dust removal, emission compliance
Using fine denier fiber and high-density needle punching technology, the filtration efficiency can reach more than 99.9%, and the combination of coating technology can meet the **ultra-low emission (<10mg/Nm³)** requirements.
4. Adapt to a variety of cleaning methods
The structure has high strength and can be applied to different cleaning modes such as pulse injection, mechanical vibration, backblowing, etc., to maintain the stable operation of the dust removal system.
5. Customizable
Support customized waterproof and oil-proof, coating, anti-static and other functional treatments to meet the needs of special industries such as dust explosion prevention, humid working conditions, fine dust filtration, etc.
6. Long service life and low maintenance cost
Under the correct selection and installation conditions, the life of the filter bag is generally 1.5~3 years, reducing the frequency of equipment downtime and the cost of filter bag replacement.
●Typical application industries
Waste incineration power plant
Cement/lime/building materials industry
Corrosive working conditions such as chemical, pharmaceutical, metallurgy, etc.
Asphalt mixing station
Power boiler dust removal system
Feed and grain processing plant (medium temperature drying tail gas dust removal)

●FAQ:

Q. What surface treatments are required for medium temperature filter bags?
A. Common surface treatments include:
Singeing and calendering: prevent dust from embedding in fibers and improve cleanability
Coating (PTFE membrane): improve filtration accuracy to submicron level
Water and oil repellent: used for high humidity or oily flue gas
Antistatic: suitable for explosion-proof occasions

Q. What industries are suitable for medium temperature filter bags?
A. Widely applicable industries, including but not limited to:
Waste incineration power plants
Asphalt mixing plants
Chemical industry (fertilizers, pesticides, resins)
Cement kilns, lime kilns
Power plant boilers
Nonferrous smelting

Q. What is the general service life of medium temperature dust removal filter bags?
A. Under normal working conditions, the service life can reach 1.5 to 3 years, but it is affected by the following factors:
Severe fluctuations in flue gas temperature → shortened service life
Acidic gas + high humidity → hydrolysis damage
Too frequent cleaning or excessive wind speed → accelerated wear
