The design of the fiber fabric of different dust-removing bags is to pursue high-efficiency filtration as much as possible, and pursue a longer service cycle. So how to choose the right dust collector bag? The dust filter sleeve is a key component of the bag filter. Generally, it needs to be determined according to the acid-base performance of the dust, the chemical nature of the gas containing the dust, the temperature of the working condition, etc., so it is different for different working conditions. The focus of selection is also different. According to the nature of the gas under the working conditions, select the suitable dust filter sock that is resistant to high temperature or humidity Temperature: The temperature is lower than 130 degrees, you can choose the conventional baghouse bag such as polyester dust bag, the temperature is greater than 130 degrees, you need to choose high temperature dust bag, such as flumesi dust bag, PTFE dust bag, etc. Humidity: The choice of gas humidity. The product engineering department of Xinwei Environmental Protection, based on actual working condition experience and test conclusions, when the relative humidity of the gas in the working condition is greater than 30%, we should choose a waterproof cloth bag with a film. Acid and alkali: Fully consider the acid and alkali properties in the working conditions. Various types of kiln boilers often contain acid and alkali. The performance is different and the corrosive working conditions. Therefore, it is necessary to choose different use of acid and alkali resistance or Anti-oxidant dust bag. The industrial filter bag is selected according to the special nature of the dust. 1. The wettability and adhesion of dust. If the dust is dust-absorbing and highly adhesive, choose a dust-removing filter bag with a waterproof membrane filter material. 2. The combustibility and nuclear power of dust. Certain dusts are flammable, and flame-retardant dust collection bags should be selected. Dust filter bags are specially used for nuclear power dust. Select the dust collection bag according to the dust removal method of the dust collector. 1. Mechanical vibration type bag filter. It is required to choose a filter material that is thin and smooth, with a soft texture, and is conducive to the transmission of vibration waves, such as PTFE dust bag. 2. Back-blowing bag type dust collector. Pulse bag filter. The outer filter round bag with frame is usually used. It is required to choose thick, wear-resistant, and strong tension resistance. For example, Metas dust bag and so on.

The working principle and steps of the circular dust bag filter are as follows: the dust-containing gas enters the filter chamber through the open flange set on the ash hopper, the coarser dust particles fall into the ash bin, and the gas containing fine dust is filtered through the filter bag. Dust is retained on the surface by the filter bag. Then the clean gas filtered by the cloth bag flows into the clean air chamber through the mouth of the bag, and then is discharged into the atmosphere through the fan. When the dust on the surface of the filter bag accumulates more and more, the programmer, that is, the pulse controller, starts to work. The pulse valves are opened one by one, and the compressed air used for cleaning dust is sprayed to clean the filter bag through the nozzle set on the blowing pipe, so that the filter bag suddenly expands. Under the action of the reverse airflow, the dust attached to the surface of the filter bag quickly leaves the filter bag and falls into the ash bin, and the dust is discharged by the ash unloading valve. The round dust collector bag is a kind of dust collector bag, which plays a key role in the bag dust collector. The filter bag should be made of high temperature resistant materials, such as fiberglass cloth/felt, NOMEX, needle felt, P84 needle felt, etc. Taking into account the durable high temperature of the filter bag and the cost and other factors, the copper industry generally chooses NOMEX needle felt. The circular dust-removing cloth bag adopts glass fiber filter material cloth bag because of its good heat resistance, high tensile strength, good dust removal and other advantages, it has been widely used in smoke and dust control. However, in the filtration of acidic flue gas produced by coal-fired boilers and garbage incinerators, the strength is greatly reduced due to acid corrosion, which affects the service life of the filter material and limits the application of glass fiber filter material in this field. The dust collector bag frame adopts a circular structure, and the longitudinal ribs and anti-support ring of the dust collector bag frame are evenly distributed. And have enough strength to prevent damage and deformation (longitudinal rib diameter ≥ φ4, 12 bars, reinforced anti-support ring φ5, spacing 200, φ130×6000). The "η" type cold-stamping short pipe is installed on the top to ensure the verticality of the bag cage and to protect the stability of the filter bag mouth during spraying. The bag skeleton bone material of the dust collector is made of 20# carbon steel, which is formed at one time by the cage bone production line to ensure the straightness and torsion of the cage bone. The filter bag frame is smooth and free of burrs after being touch-welded, and has sufficient strength to prevent welding, false welding and missing welding. The bag frame of the dust collector adopts organic silicon spraying technology, the coating is firm and corrosion-resistant, which avoids the rust of the ...

On December 24, Wang Huachen, deputy head of the United Front Work Department of the Municipal Party Committee, Chen Shunyun, a third-level investigator, and heads of related departments came to Yuanchen Technology to visit and sympathize with the needy employees of the enterprise, and pass the care and warmth of the party and the government to the production line.
