Introduction to Four Types of Filter Cloth and Ash Removal Technologies 1120
Introduce the four major varieties and dust removal technologies
Filter cloth is an important component of filter cloth. The extension of the service life of sludge filter cloth and filter bag, the reduction of cleaning times, and the reduction of equipment maintenance costs. Based on the properties and particle size of sludge, the selection of filter cloth that can effectively intercept sludge particles during filtration is mainly based on the pore size and permeability (air permeability) of the filter cloth. Polypropylene filter cloth is close to zero emissions and can meet the strictest environmental standards; Good dust cleaning performance, can provide higher ventilation or reduce pressure difference. To a large extent, the quality of the filter cloth determines whether the user has a filtering effect. Filter cloth experts explain the types of filter cloth and dust removal techniques. So, what are the types of filter cloth and how do they remove dust? Let's take a look at it.
Expert sample:
One. According to the filtering method, it can be divided into external filtering and internal filtering.
2. According to the usage environment and temperature resistance program, it can be divided into room temperature, medium temperature, and high temperature.
According to the shape of the cross-section, it is divided into flat bags (trapezoidal and flat) and circular bags (cylindrical).
4. The air pressure that comes out is divided into: at the inlet of the wind and the DC type (flat bag restriction) of the wind blower.
Experts introduce the techniques of dust cleaning methods
1. Manual tapping: Manually tap each filter cloth to remove dust from the filter cloth.
2. Mechanical vibration cleaning: With the help of a mechanical vibration beating device, regularly tap each row of filter cloth to remove the accumulated dust on the filter cloth.
3. Cleaning gas: The method of purifying the filter cloth with high-pressure gas or external air to remove dust from the cloth. Clean gas pulse blowback, including reverse air purification and reverse cleaning.
