Application scope of crushing yard dust removal equipment
The dust removal equipment of the crushing yard is also called the bag factory dust collector of the stone material factory and the dust collector of the sand stone factory. It is suitable for the tiny particles produced by various types of crusher of the stone crushing yard. The crushing field dust removal equipment produced by Novo Corporation has the advantages of large processing capacity, stable work, high purification efficiency, and convenient work and maintenance. Building materials, highways, railways, water conservancy, chemical industry and many other industries.
The crushing field dust removal equipment has a simple structure, high dust removal effect, convenient maintenance, and no need for personnel care. It is especially suitable for small and medium-sized stone and quarry dust removal and purification systems.
The dust removal mechanism of the dust removal equipment of the crushing yard <br The dust removal equipment of the crushing yard uses compressed air as the dust , and uses a pulse blowing system to release the compressed air instantly, and induces multiple times of secondary air to be injected into the filter bag at high speed. A bag-type dust collector that sharply swells the filter bag and removes dust by shock vibration and back blowing airflow. Pulse bag filter has high purification efficiency, large gas processing capacity, stable performance, convenient operation, long filter bag life, and small maintenance workload. In addition, structural and pulse valve reforms have been adopted to solve the problems of open air installation and low compressed air pressure.
The crushing yard dust removal equipment uses a mechanical rotary anti-blow flat bag dust collector with the most reasonable design, simple structure, stable operation, convenient daily operation and maintenance, and almost no wearing parts. Mechanical rotary counter-blow flat bag type dust collector belongs to low-energy dust removal and external filtering type bag type dust collector. Its filter bag adopts flat bag, and the cross-sectional shape of the dust filtering bag is made trapezoidal or wedge-shaped. Comparing with the round filter bag, under the condition that the filtering load per unit area of the filter cloth is not different, its footprint is small and the structure is compact, that is, more filtering area can be installed in a unit volume. Compared with other bag-type dust collectors, the comprehensive performance has more advantages. To this end, our company uses a mechanical rotary back-blow flat bag duster to remove dust from the quarry crusher of the quarry. Compared with the pulse bag dust collector commonly used in China, the mechanical rotary counter-blow flat bag dust collector has the following characteristics: The casing is designed according to the volute type inlet of the cyclone dust collector, which can play a local cyclone role and reduce the load on the filter bag. During the production process of the quarry, dust will occur on many process equipments. To make the dust production points of the quarry reach the national standard production conditions and the exhaust gas to meet the national emission standards, the dust generated at the dust production points must be controlled. . The dust collector has been widely used in quarries and stone factories across the country, and both have achieved relatively ideal operating results.
Crushing yard dust removal equipment Common dust production point Dust management steps1. Mining material crushing system Dust collector for raw material ore, lump ore and crusher or crusher feeding port of limestone, dolomite, bauxite, raw coal and other raw materials Closed devices or dust collection hoods are set at the mouth, the upper part of the vibrating screen and the transfer point of the belt conveyor. Double-layer closed hoods should be set up at the receiving point of the transfer point. Cover the dust-producing equipment with a closed cover, or build a dust collection chamber to form a uniform negative pressure in the hood to prevent dust from escaping, or use an open suction hood to form a suction airflow to control the exposed dust area in a narrow area. Within the range, the dust-carrying airflow is sucked and taken away, purified by a dust collector, and discharged into the atmosphere through an exhaust pipe (or chimney),
2. The unloading truck on the mixing batching tank and the quantitative feeding station under the tank should take the dust removal step. The dust generated by the unloading truck on the tank can be a mobile tuyere ventilation tank or a vehicle-mounted dust collector, or a large-volume 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 the dust in the mixing batching tank, an independent dry dust removal system should be set up, using a bag dust collector,
3. Raw coal crushing and conveying dust removal system should take professional steps. The dust collector is a bag-type dust collector, and the dust-removing cloth bag should have an anti-static function; the system and equipment should be grounded statically, and an explosion-proof device should be provided. The ash bucket should take the steps of heat preservation or heat tracing,
4. The dust extraction system of the raw material yard includes ore crushing, screening and dust removing systems, limestone crushing, screening and dust removing systems, aluminum ore crushing and dust removing systems, and coal crushing and dust removing systems. For dust production equipment collection, dust production points with the same dust properties and the same working system, try to use a large collection dust removal system to facilitate management, such as limestone crushing, screening and dust removal systems, as many as dozens of dust production points are collected in a large system in. Otherwise a small decentralized system can be used. In various dust removal systems, dry high-efficiency bag dust collectors are mostly used. The shape of the cylindrical vault is uniformly stressed and has good anti-explosion performance.
The crushing yard dust removal equipment adopts the equipment supporting high-pressure fan to blow back the ash, which is not limited by the air source conditions of the application. It has few wearing parts, simple protection, reliable operation, and overcomes the disadvantages of compressed atmosphere pulse ash cleaning. Large working distance, long filter bag can be used, make full use of space, and occupy a small area. The ladder-shaped flat bag is arranged in the cylinder, the structure is simple and compact, and the filtration area index is high. Under the action of anti-blowing, the trapezoidal flat bag has a large amplitude, and it can shake off the accumulated dust with only one vibration, which is conducive to improving the life of the filter bag. The resistance of the dust collector of the quarry stone plant's mine crusher dust collector is used as a signal, which can automatically control the rotary backflush dust removal, and automatically adjust the dust removal cycle depending on the rugged inlet concentration. The upper cover of the dust collector is divided into multiple pieces, which can be opened and changed at will, and maintenance is very convenient. After several designs of the quarry stone plant's mine crusher dust collector, the inlet concentration does not have to be limited to 15 g / m3. It is not necessary to add a cyclone dust collector even at 150 g / m3. This equipment has the function of cyclone dust collector, but there is no resistance of cyclone dust collector. Although this equipment adds cost, the price will not increase. Except in severe cold areas, the dust removal equipment of the gravel yard can be set up outdoors and in the open air, without the need to build a dust collector.
