Room temperature/high temperature pleated cloth bag

Room temperature/high temperature pleated bag is an effective dust removal filter bag made through three-dimensional pleating technology. The filtering area in the same space can reach 1.5-3 times that of traditional circular bags. The room temperature version is suitable for working conditions ≤ 130 ℃, and the high temperature version is suitable for working conditions 130-280 ℃, combining the core advantages of compact energy saving and effective filtration.

Core Definition and Structure

Structure: The filter material is finely pleated into waves/spiral folds, with a pair of folded skeletons (longitudinal bars+ring braces) built in, with a fold spacing of 8-15mm, to confirm uniform airflow and stable shape.

Principle: The three-dimensional folds greatly enhance the filtering area, reduce the filtering wind speed and system resistance, clear the dust thoroughly, and stabilize the emission concentration below 10mg/m ³.

Mainstream materials and processes

Substrate: Polyester needle punched felt (350-600g/㎡), optional PET/PTFE coating, post-treatment including singeing, calendering, heat setting, and three proofing (based on actual reports) (based on actual reports) (based on actual reports).

Skeleton: Low carbon steel/galvanized+(based on actual reports) (based on actual reports) silicon coating, suitable for wrinkle morphology, corrosion (based on actual reports) (based on actual reports) anti adhesion.

Key performance (typical values)

Applicable scenarios: Building materials (cement mills), food processing, feed, flour, mechanical processing, mining crushing, pharmaceuticals (non high temperature) and other low corrosion working conditions at room temperature.

High temperature pleated cloth bag (130-280 ℃)

Mainstream materials and processes

Process: Composite needle punching+PTFE coating/impregnation, wrinkles are shaped at high temperature (180-220 ℃) to confirm structural stability.

Key performance (typical values)

Applicable scenarios: high temperature, high corrosion, and high viscosity dust conditions such as cement kiln tail, garbage incineration, hazardous waste disposal, steel smelting, asphalt mixing, coking, and calcium carbide furnaces.

Core advantages and selection points

Core strengths

Compact effect: The filtering area of the same box is increased by 50% -200%, the land occupation is reduced by 40%, and it is suitable for the renovation of old systems.

Energy saving and consumption reduction: Reduce wind speed by 30% -50% and fan energy consumption by 20% -30%.

Excellent dust cleaning: The wrinkled structure reduces dust compaction, and the pulse cleaning dust stripping rate is ≥ 90%.

Selection, Installation, and Maintenance

Selection: Choose polyester triple proof/film coating at room temperature; Select PPS at 180-240 ℃; Beauty Pageant Tas/P84 at 240-260 ℃; Strong corrosion and high humidity PTFE; (Based on actual reports) (Based on actual reports) requires blending conductive fibers.

Installation: The skeleton has no burrs, the coating is not damaged, the gap between the filter bag and the skeleton is 2-5mm, and the seal is in place.

Maintenance: Clean the dust at a pressure of 0.2-0.4MPa, regularly check the pressure difference and discharge, and replace damaged filter bags in a timely manner.
