Called the heart of the baghouse dust bag, generally known as a dust bag or dust filter bag, dust bag is a key part in the baghouse during operation, usually cylindrical bag vertically hanging in the dust collector. 
 Pulse and air box pulse dust collector, dust is attached to the outer surface of the bag. Dusty gas after dust collector, dust is captured in the outer surface of the filter bag and clean gas enters into the bag through the filter internally. Bag inside cage to support the filter bag to prevent bag collapse, while it helps to clear and re-distribution of the dust cake. 
 Filter or dust removal equipment is dust from the flue gas to separate the device. The bag filter is also known as filter dust collector, a dry-type high-efficiency dust collector, which is the fiber braid bag filter elements to trap solid particles in the dusty gas dust removal device. Its mechanism is dust to bypass the filter cloth fiber was blocked due to inertial force and the fiber collision. 
 The fabric and design of the dust bag should be the pursuit of high-efficiency filter, easy-to-dust stripping and durable effect. The selection of the dust bag is essential, it has a direct impact Precipitator effect, select the dust bag selected choose from the following aspects: the gas temperature, humidity and chemical resistance, particle size, dust concentration, filtration velocity, clear dust way. 
 The dust bag is to determine the dust collecting efficiency and working temperature of key components, the cost to replace the dust bag baghouse maintenance costs. 
 Select the filter according to the temperature, humidity, and chemical properties of gases; particulate matter size, weight, shape, and dust concentration, filtration rate, cleaning methods, emission concentrations and baghouse system of work and other factors considered. 
 Our production of dust bag design and reasonable structure, long working life, to ensure a dust collector in good working condition, and operating cost.

 The advantages of dust bag: 
 A. The dust removal efficiency, 0.3nm above can trap dust, dusty gas purification to 15mg/m3 even. Two. Trapping the dust of the electrostatic precipitator is difficult to recycle; and be able to collect a certain level of nitrites, sulfides and other compounds. 3. Load changes in compliance, especially for trapping fine and boring dust collected dry dust for easy disposal and recycling applications. 4. Baghouse collection contains Ping higher risk of explosion or dusty gas with a spark. 
 Defects of dust bag: 
 A. Different types of gas should be used in the corresponding type of the bag; and needs often change Toi Toi consuming a large amount of 
 Two. Collect high humidity, dusty gas, moisture measures should be taken to avoid condensation and to form a paste bag, and thus dust bag air humidity of the gas have a certain request. 
 3. Resistance, the ordinary pressure loss for 1000 ~ 1500Pa. 
 The utilization rate of the domestic dust bag from time to time progress, the use of life to reach more than four or five years is also increasing. In addition, the PTEF membrane, the composite filter media, such as advanced filtering information technology research and development is not new to break.
