The selection of dust removal filter bags should be based on the temperature, humidity, and chemical characteristics of the gas; The size, weight, appearance, abradability, dust concentration, filtration speed, ash removal method, emission concentration, and working system of the bag filter of the particulate matter shall be comprehensively considered. Generally, needle felt dust removal filter bags are selected for pulse jet bag filters, and woven fabrics are selected for chamber reverse blow bag filters or mechanical rapping bag filters.
Application of Dust Removal Bags in Various Industries
1. Dust removal bags are generally divided into rapping type dust removal bags, pulse type dust removal filter bags, and reverse blow type dust removal bags according to the different dust removal methods. There are also round bag types, flat bag types, and envelope types depending on the shape. There are also different bag opening and bottom design methods for dust removal bags to choose from. At the same time, small dust removal bags are suitable for cutting operations, drilling operations, grinding operations, packaging operations, powder input operations, sanding operations, cutting operations, mixing operations Environments such as crushing operations
2. Dust removal cloth bag is a dry dust filtering device. It is suitable for collecting fine, dry, and non fibrous dust. The filter bag is made of textile filter cloth and non textile felt. It uses the filtering effect of fiber fabric to filter dust containing gases, and is suitable for dust removal and treatment in industries such as metallurgy, ceramics, chemical engineering, grain processing, machinery manufacturing, and mining. A good dust removal device can achieve a dust treatment effect of 99.9%. Waste incinerators, coal-fired boilers Fluidized bed boiler and other flue gas filtration; asphalt concrete mixing; production sites such as building materials, cement ceramics, lime, gypsum, etc.; aluminum electrolysis, smelting flue gas filtration of zinc, copper, lead, tin, and other rare metals; fine material recovery, liquid solid separation; liquid solid separation and fine material recovery in the fields of dyes, chemicals, coke, carbon black, pharmaceuticals, plastics, etc.; mining, electronics industry, wood processing, grain processing Dust control and purification collection of flour, etc
Dust removal bags are widely used in the dust removal of ball mill cast iron machines in cement plants. In the high-temperature flue gas filtration of various industrial furnaces such as chemical industry, iron and steel, metallurgy, carbon black, power generation, cement, etc., dust removal filter bags are suitable for various bag type dust collectors such as pulse dust removal and relatively high-speed reverse blowing dust removal. They have the characteristics of high strength, low elongation, strong acid resistance, and weak alkali resistance.
There are various types of dust removal cloth bags (dust removal filter bags), including glass fiber woven filter bags, glass fiber pricked filter mats (filter bags/cloth bags), Flumex (FMS) high-temperature resistant needle punched filter material cloth bags, high-temperature resistant METAS dust removal cloth bags, 208 cloth bags, 729 cloth bags, polypropylene fiber pricked filter mats (filter bags/cloth bags), water and oil repellent cloth bags, polyester antistatic needle punched filter mats (filter bags/cloth bags), high-temperature resistant dust removal cloth bags, normal temperature dust removal cloth bags A variety of dust removal filter bags are available for you to choose from, including glass fiber high-temperature resistant needle felt, polyester easy dust removal needle felt, P84 filter cloth bag, PPS needle felt, acrylic temperature resistant, medium temperature needle felt, and normal temperature film covered needle felt. Key accessories in the bag filter: The dust removal bag must be properly coordinated with relevant components, such as the external filter type synthetic fiber filter bag that should be loosely coupled, the external filter type glass fiber filter bag that should be closely coupled with a small spacing vertical rib frame, and the internal filter bag that should consider and set the tension of the filter bag. The structure of the dust removal filter bag should meet the requirements of its matching bag filter for filtering and dust removal, and should be installed easily and sealed reliably, Pursue appropriate filtration area and good filtration state, easy to clean and avoid abrasion as much as possible
