喷雾除尘典型应用(下)

物料铁路运输防尘
煤矿、铁矿石以及其它各种矿料在开采或加工完毕后,采用火车运 输的方式运输到码头及其它目的地。在少则几十多则数千公里的运 输途中,产生大量的煤尘、矿粉尘,这些粉尘飞扬到周围空气中, 对沿途环境造成污染。部分粉尘沉落到铁轨上或铁轨接合处,形成 火车行驶的安全隐患。 采用先进的喷雾技术可以保证保护膜产生的质量, 节约投资和降低运行成本,通过对喷雾各种参数的 分析可以确认最合理的解决方案。采用的粉尘抑制 剂在一定期限内自然降解,绝对不会影响物料特性 和质量。 采用在线向火车内的物料表面喷射粉尘抑制剂的方法,可 以使物料表面形成具有一定强度的保护膜,在自然条件下 粉尘不再产生。使用这种方法不仅可以保护环境,而且减 少物料在运输途中产生的耗损。

中间包翻包除尘
在连铸设备中,中间包用于承装钢水。在每次修砌内衬耐火材料前, 需清理中间包中残余的耐火材料和钢渣,将大量残留物倒出来,中间 包翻包时会产生大量的粉尘,主要特点是瞬时粉尘量特别大、有时具 渣罐除尘 有比较高的温度。
由于翻包台在厂房内,有吊车频繁作业,采用常规的烟罩通风除尘系统,现 场布置、操作都比较困难,又由于空间和风量大,所以采用烟罩通风除尘系 统投资较高。
采用喷雾除尘不仅投资少,而且实施容易,除尘效率高,完全可以满足环保和岗位卫生 要求;另一方面,水雾除尘系统运行费用很低,还可以利用和处理废水。

翻车机、卸车机等物料装卸除尘
翻车机、卸车机在工作的时候,物料由于倾卸过程中 的撞击,瞬间倾覆而产生大量翻转性粉尘,粉尘瞬间 爆发造成严重污染。
采用喷雾除尘的方式,通过合理的喷雾装置配置,通过水 雾对灰尘的捕捉、阻挡作用,能够有效控制物料装卸过程 中产生的粉尘。

Material dust of railway transportation
Coal, iron ore and other various ore materials in mining or processing has been completed, with the method of the train transport transport to the port and other destinations.In little has dozens of many thousands of kilometers of the transportation on the way, have a lot of coal dust, mine dust, the dust float in the sky into the surrounding air, damage to the environment.Part of the dust sinks down to the track or tracks joint, forming trains safe hidden trouble.Advanced spray technology can guarantee the quality of protective film to produce, save investment and reduce running cost, through the analysis of spray parameters can determine the most reasonable solution.With the dust suppression agent within a certain period of natural degradation, absolutely will not affect the material properties and quality.Using this online material inside the surface spray dust inhibitor method, in order to make the material surface can be formed with a certain intensity of protective film, under the condition of natural dust no longer produces.Using this method can not only protect the environment, and reduce the material loss produced during transit.
 
Tundish bag dust removal
In continuous casting equipment, tundish for bearing steel.Build by laying bricks or stones before lining refractories in every time, and need to clean the residual in the tundish refractory material and steel slag, taken out a large number of residues, tundish double package will produce large amounts of dust, the main characteristic is instantaneous particularly large amount of dust, sometimes with slag pot has a relatively high temperature of dust.
Due to the double package units within the building, a crane operation frequently, using conventional hood ventilation dust removal system, now the field layout, operation is more difficult, and because of the space and the air volume is big, so the hood ventilation dust removal system All investment is higher.
Using spray dusting less investment not only, and easy implementation, high dust removal efficiency, can satisfy completely the requirements of environmental protection and health;Water spray dust removal system, on the other hand, operation cost is low, and can be used to wastewater treatment.
 
Car dumper, unloading machine, etc material loading and unloading of dust removal
Car dumper, unloading machine at work, in the process of material due to dump, turn moment capsized and produce a lot of dust, dust instant eruption caused serious pollution.
With the method of spray dusting, through reasonable spray device configuration, through the water fog of dust capture, blocking effect, can effectively control the material dust produced in the process of loading and unloading.
