High-temperature dust-removing cloth bag for biomass boiler——Junzheng environmental protection spot supply
The biomass boiler's combustion medium is straw, rice straw, fuelwood, wood chips, peanut husks, melon seed husks, sugar beet meal, bark and other abandoned crops, which are destroyed, mixed, kneaded, and dried to make granular fuel. . Biomass boiler fuel is famous for green coal and is a clean power.
The high-temperature dust-removing cloth bag for biomass boiler is a kind of high-efficiency dust-removing filter material, which has good ventilation performance. The high-temperature dust-removing cloth bag for biomass boiler has high efficiency, and has certain acid resistance, alkali resistance and heat resistance. Brushed, increase the thickness of the fabric, give elasticity, dust removal accessories are very effective, the dust removal rate can reach 99.99%. The high-temperature dust-removing cloth bag for biomass boiler adopts polyester staple fiber or long fiber as the material, and the service life is generally 4-6 times that of glass fiber fabric. It has good air permeability, high dust collection rate, dust removal capacity, and dust removal efficiency is up to 98.99%. The high-temperature dust-removing cloth bag for biomass boilers is dirty during the operation of the bag-type dust collector. Generally, a cylindrical pulse filter bag is suspended vertically in the dust collector, and the dust-containing gas enters the dust collector from the air inlet and passes through the dust hopper. The flow plate makes part of the large particles of dust in the gas subject to inertial forces and is separated directly into the ash hopper. Dust-containing gas enters the filter bag filter area of the box, and most of the dust is trapped on the outside of the filter bag. The clean gas enters the inside of the filter bag through the filter material, and the purified gas enters the upper case through the filter bag mouth, and then is discharged through the air outlet. The cage inside the filter bag is used to support the filter bag and prevent the filter bag from collapsing. Together, it helps to remove and redistribute the dust cake.
Common types of high-temperature dust-removing cloth bags for biomass boilers are:
1. PPS (polyphenylene sulfide) high temperature dust-removing cloth bag for biomass boiler: long-term operation temperature is below 170 ℃, it has good flame resistance and abrasion resistance, high heat resistance, resistance to acid and alkali, widely used in Dust collection treatment of coal-fired boilers, waste incinerators, and fly ash from power plants;
2. P84 (polyimide) high-temperature dust-removing cloth bag for biomass boiler: temperature resistance 230 ℃, high temperature resistance, high strength, high air permeability, long life and more corrosion resistance;
3. PTFE (polytetrafluoroethylene) high-temperature dust-removing bag for biomass boilers: temperature-resistant to 260 ° C, and its function is more excellent than that of P84 (polyimide) biomass-fired high-temperature dust-removing bag!
In order to reduce costs, the following two types of high temperature dust bag for biomass boilers / high temperature dust bag for high temperature biomass boilers can be considered under the conditions of the dust collector:
1. High-temperature dust-removing cloth bag for glass fiber composite biomass boiler: temperature resistant to 280 ° C, but the fiber is easy to fold and the life is short, and the filtering wind speed is 0.6 m / min;
2. Aramid fiber biomass boiler high temperature dust-removing cloth bag: instantaneous temperature resistance of 250 ℃, long-term temperature resistance of 200 ℃, weak corrosion resistance, the flue gas filtration after desulfurization and deacidification may be used after corrosion resistance treatment.
High-temperature dust-removing cloth bags for biomass boilers are generally divided into high-temperature dust-removing cloth bags for pulse-type biomass boilers, high-temperature dust-removing cloth bags for vibrating biomass boilers, and back-blown dust-removing dust bags according to different cleaning methods. There are also round bag type, flat bag type, and envelope type. There are also different bag mouth and bag bottom planning methods for high temperature dust removal cloth bags for biomass boilers. Leak detection for bag dust collectors has been a major problem for many years, and there are huge social and economic benefits in dealing with this problem. Large bag-type dust collectors may consist of thousands to tens of thousands of filter bags. If one or two filter bags are found to be damaged, it is not easy. In general, the replacement cycle of filter bags is 2-3 years. Not every filter bag needs to be replaced every time it is replaced, and only a few or even a few are damaged, and most of them are intact. The damaged filter bag can be replaced and repaired, which can extend the whole replacement cycle and ensure the filtration efficiency of the dust collector. The working principle of the bag filter is a filtering type dust removal device based on the filtering principle, which uses organic fiber or inorganic fiber filter cloth to filter out the dust in the gas.
Our filter media products are made from a variety of synthetic fibers, each with its own unique function. We can almost infinitely combine all kinds of fibers, and then plan an all-inclusive skills plan to precisely meet the special needs of different uses. The product range includes gas-solid and liquid-solid separation filters, as well as filters used under various conditions such as high temperature, low temperature, and dry; in addition, we can also perform different physical and chemical treatments on the filter. The dust collector bag is an important accessory on the dust collector. Its primary function is to store the dust and dust collected by the dust collector. Therefore, the quality requirements of the high-temperature dust collector bags for biomass boilers are very high, especially in some In a corrosion-resistant environment, the dust collector bag has a corrosion-resistant function. The company's skills are checked at various levels, and unqualified products are prevented from entering the environmental protection market. As a result, the company has been recognized by new and old customers. Please also be attentive to our products!
