Mine raw material crusher air box pulse bag filter
Introduction The air box pulse cloth bag is out of the car and you are going to introduce a new product from Fudong Company. This series of products can be widely used in the crushing installation, storage roof, cooked cooler and mill of cement plant.
This series of products has a total of 33 specifications. There are four types of bags in each room: 32, 64, 96, and 128 bags. The length of the dust filter bag is 2450mm and 3060mm. The dust collection efficiency can reach more than 99.9%. If the concentration is less than 100mg / m3 (standard), if this series of dust collectors are used in cold areas, when the calculated outdoor heating temperature is ≤-25 ° C, a heating device shall be provided.
In the process of production of the ore dressing plant, dust will be generated on many process equipment. If the dust production point of the ore dressing plant meets the national standard production conditions and the exhaust gas reaches the national emission standard, the dust generated at the dust production point is controlled. According to the mine, The characteristics and properties of dust, of course, the air box pulse bag filter is an ideal choice. The air box pulse bag filter has been widely used in a wide range, and they have achieved relatively ideal operating results. Below we introduce the dust control measures and selection of dust removal equipment at several common dust production sites in the ore dressing plant. For technical support, please go to the technical department of the power company
1.Mine raw material crushing system Bag filter removes raw material ore, lump ore, crusher or grinder of raw materials such as limestone, dolomite, bauxite, raw coal and other materials. Feeding port, discharge port, upper part of vibrating screen and belt conveyor. Closed devices or dust collection hoods should be provided at points and other places, and double-layer closed hoods should be provided at the receiving point of the transfer point.
Cover the dust-producing equipment with a closed cover or make a dust collection chamber to make the negative pressure uniform in the hood to prevent the dust from escaping, or use an open air hood to form a suction airflow to control the exposed dust area in a narrow area Within the range, the dust-carrying air stream is sucked and taken away, purified by a bag filter, and discharged into the atmosphere through an exhaust pipe (or chimney).
2. Dust removal measures shall be taken on the unloading truck on the mixing batching tank and the quantitative feeding station under the tank. The dust generated by the unloading truck on the tank can be a mobile tuyere ventilation tank or a vehicle bag-type dust collector, or a large-capacity closed cover can be provided. A double-layer closed cover should be provided for the dust generated by the quantitative unloading device under the tank. For dusting of the mixing batching tank, an independent dry dust removal system should be set up and a bag dust collector should be used.
3. Professional measures should be taken for the raw coal crushing and conveying dust removal system. The bag dust collector is a bag type dust collector. The dust bag should have an antistatic function; the system and equipment should be grounded statically and a vent device should be provided. The ash bucket should adopt heat preservation or heat tracing measures.
4. The ventilation and dust removal system of the raw material yard includes ore crushing, screening and dust removing system, limestone crushing, screening and dust removing system, aluminum ore crushing and dust removing system, and coal crushing and dust removing system. For dust production sites with concentrated dust production equipment, the same dust properties and the same working system, try to use a large centralized dust removal system to facilitate management. For example, limestone crushing, screening and dust removal systems, as many as dozens of dust production points are concentrated in one large system. in. Otherwise a small decentralized system can be used. In various dust removal systems, dry bag dust collectors are mostly used.
