PPS power plant special high-temperature dust bag
The excellent temperature resistance and chemical stability of the special high-temperature dust-removing bag for PPS power plants are determined by its simple chemical structure. Because its shapes are symmetrical to each other and highly linear, its effect PPS can be crystallized very quickly and very easily, and can reach the degree of grade. Thus, it exhibits a melting point of 285 ° C, and it has excellent heat resistance. In addition, its flame retardancy, chemical resistance, and standard stability are also excellent. It has various characteristics as a high-performance fiber. PPS power plant special high-temperature dust-removing cloth bags can withstand temperatures of 190 ℃ in succession, and resist many chemical corrosion of acids, alkalis and oxidants. It is important that the special high-temperature dust-removing cloth bags for PPS power plants do not hydrolyze, so they can replace Nomex fibers at high temperatures under wet, chemical (such as sulfur dioxide) conditions. The high-temperature dust-removal cloth bag for PPS power plants, like polypropylene, has a moisture absorption rate of only 6%, but the temperature is much higher.
PPS dust bag as the heart of the bag type dust collector mainly depends on the filtering power of the filter itself, the degree of ventilation, and various chemical functions. Because the traditional filter media has a strong single function, it cannot excel in the face of corrosive gases such as acids and alkalis. Therefore, before changing the production process and equipment structure, it is important to consider the selection of filter bags. Selection, in many practices, the advantages of PPS dust bag are more outstanding.
During the production process of the special high-temperature dust-removing cloth bags for PPS power plants, we high-speed needle punched 1.5D × 51mm PPS fibers and glass fiber base fabrics to form a three-dimensional pore structure, which has superior acid and alkali resistance and high temperature resistance. When receiving high-temperature flue gas, it can insist that the filter material is not deformed and not ripened. It can give full play to its advantages in many high-temperature and high-corrosion flue gas filters, so that the equipment work is more secure and the protection cost is lower.
The special high-temperature dust-removing cloth bag for PPS power plant is a kind of high-temperature resistant synthetic fiber. The continuous operating temperature can reach 170 ° C and the instantaneous temperature is 190 ° C. PPS fiber has excellent mechanical and chemical functions, can adhere to excellent filtering functions in harsh environments, has excellent standard stability, flame resistance, etc., has excellent resistance to hydrolysis and acid and alkali corrosion, and has high performance fibers Various characteristics. It can work normally under the conditions of moisture in the flue, sulfur in the flame or sulfur oxide in the flue gas.
PPS power plant special high-temperature dust-removing bag is a kind of filter material made of PPS fiber (polyphenylene sulfide) through three-dimensional needle punching. It can be used for a long time at a temperature of about 190 ° C.
Due to its special molecular structure, the high-temperature dust-removing cloth bag for PPS power plants has good chemical stability and strength. It is particularly effective in flue gas environments with high sulfur content. High-acidity flue gas filtering environment such as incineration, the special high-temperature dust-removing bag for PPS power plants is a dust-removing bag for coal-fired boilers.
Features of high temperature dust bag for PPS power plant:
1. Operating temperature: 190 ℃, short-term operating temperature: 232 ℃, melting point: 285 ℃, oxygen index: 34 ~ 35.
2. It can be used in the place with oxygen content of 15% or below.
3. The sulfur-containing oxide in sulfur or flue gas has been proved to be a fiber resistant to acid and alkali and strong chemical resistance.
4. Moisture in the flue.
5. When the temperature is 190 ℃ ~ 232 ℃, the air-to-cloth ratio is as high as 5: 1 for online cleaning and the air-to-cloth ratio is 6: 1 for offline cleaning. PPS filter bag has excellent performance record.
The PPS power plant special high-temperature dust-removing bag has the strength of persistence and inherent chemical resistance. It can maintain excellent filtering function in harsh environments and reach the intended service life. In the pulse ash cleaning type dust collectors such as filtering coal-fired boilers, waste incinerators, and dust collection treatment of power plant fly ash, special high-temperature dust-removing bags for PPS power plants are the aspiration filter materials.
The degree of surface lubrication of the dust filter bag filter has a great influence on the dynamic working resistance of the filter. The initial resistance of the dust filter bag filter is determined by the air permeability of the filter itself, and the resistance during work is many times larger than the initial resistance. The working resistance depends on the degree of lubrication on the surface of the filter bag and the dust removal effect. The choice of dust-removing bag cloth depends on the dust properties of the dust, and whether the dust contains acids, alkalis or corrosive substances should be considered. According to the nature of the dust, a suitable filter material is selected, so that the filter bag can normally absorb the dust without affecting its service life. The correct selection of the appropriate dusting cloth bag is the key to the filter bag. If the temperature is too high, the dust bag used will exceed the normal operating temperature, the filter bag will shorten the service life, and it will burn in a short time. Therefore, when selecting a filter bag, the inlet temperature of the dust collector must be measured and calculated. Select the corresponding dust filter bag.
