饲料加工车间冷却除尘系统设计:饲料车间的生产工艺通常由接收、加工和贮运等工序组成。在原料的混合、精选、调配工序,配合料的粉碎、筛分、分级工序以及成品的包装、转运、仓储等工序处易产生扬尘。原料以散装或包装形式注入料仓,投料口是一个集中污染源,需采取收尘措施。对辊式粉碎机将物料粉碎,同时产生机械热和游离水分,需采取通风收尘措施,气力输送、风选设备的尾气必须借助收尘器实现气固分离。
Design of cooling and dust removal system in feed processing workshop: the production process of feed workshop is usually composed of receiving, processing, storage and transportation. It is easy to produce dust in the processes of mixing, cleaning and blending raw materials, crushing, screening and grading of batch materials, and packaging, transportation and storage of finished products. The raw materials are injected into the silo in bulk or in package, and the feeding port is a centralized pollution source, so dust collection measures should be taken. The material is crushed by the counter roller mill, and mechanical heat and free moisture are produced at the same time. Therefore, ventilation and dust collection measures should be taken. The tail gas of pneumatic conveying and air separation equipment must be separated by means of dust collector.
饲料加工时,粉尘粒径粗、密度小(堆积密度为0.2~0.3g/cm3)、粘附性强、空隙率大、流动性差。饲料加工时,粉尘本身无毒,但如果长期接触,易引起人体呼吸系统疾病,另外粉尘会加速饲料机械部件磨损,造成电器设备失灵,当粉尘浓度达到一定程度时,还会引起爆炸。
车间除尘设备
In feed processing, the particle size of dust is coarse, the density is small (bulk density is 0.2 ~ 0.3g / cm3), the adhesion is strong, the porosity is large, and the fluidity is poor. In feed processing, the dust itself is non-toxic, but if long-term contact, it is easy to cause human respiratory diseases. In addition, the dust will accelerate the wear of feed mechanical parts, resulting in the failure of electrical equipment. When the dust concentration reaches a certain level, it will also cause explosion.
除尘系统设计及设备选型:
Dust removal system design and equipment selection:
1)宜采用短流程设计,少用弯头,减少除尘管路,优先选用袋式收尘单机(脉冲布袋除尘器);
1) Short process design should be adopted, elbows should be reduced, dust removal pipelines should be reduced, and bag type dust collector (pulse bag filter) should be preferred;
2)在气力输粉及风选系统,粉尘浓度高,宜采用旋风+袋式两级除尘工艺;
2) In the pneumatic powder conveying and air separation system, the dust concentration is high, and the cyclone + bag type two-stage dust removal process is suitable;
3)选用专为饲料收尘设计的脉冲喷吹类袋式收尘器和袋式收尘机组,采用消静电滤料;
3) The pulse jet bag filter and bag filter unit specially designed for feed dust collection are selected, and the anti-static filter material is used;
4)收尘器灰斗采用圆锥形或圆角方锤形,并设振动器,防止棚料,当用于饲料粉碎机收尘时,壁面还应保温;
4) The dust hopper of the dust collector adopts conical or rounded square hammer shape, and is equipped with a vibrator to prevent shed materials. When it is used for dust collection of the feed grinder, the wall surface should also be insulated;
5)对大型提升机、皮带机、刮板机等输送设备,机内粉尘浓度较高(标准状态下可达5~ 15 g/m3),宜采取头部、尾部或中部多设置吸尘点,以防引发饲料机械爆炸。
5) For large-scale elevator, belt conveyor, scraper and other conveying equipment, the dust concentration in the machine is high (up to 5 ~ 15 g / m3 under standard state), and more dust collection points should be set at the head, tail or middle to prevent the explosion of feed machinery.
