Description

一种利用惰性气体带走生成蒸气的装置A device that uses inert gas to take away the generated steam

技术领域technical field

本发明涉及干燥机技术领域,具体为一种利用惰性气体带走生成蒸气的装置。The invention relates to the technical field of dryers, in particular to a device that uses inert gas to take away generated steam.

背景技术Background technique

现有的喷雾干燥机为利用惰性气体干燥的一种设备,采用雾化器将物料液分散为雾滴,并用热气体干燥雾滴而获得产品,主要工作过程是:外界新鲜空气通过空气过滤器、鼓风机,进入空气加热器,使空气温度提高到 160℃左右,送进干燥塔,在进入干燥塔前,热空气先通过均匀风板,使热空气均匀分布,防止旋涡,避免焦粉发生,以保证干燥效果。需干燥处理的物料液,由压力泵送至雾化器,料液以雾状喷出并与热空气混合,物料微粒吸取热量,瞬间水分蒸发,形成粉末向下降落,经过一段恒速干燥,进一步蒸发水分,粗颗粒落入干燥塔的底部并排出,干燥后的物料细粉粒和低温湿空气的混合物经旋风分离器分离,废空气由排风机排放,干燥细粉末产品落下由卸料器连续排出,喷雾干燥机在工作时,潮湿物料被甩到干燥塔壁上以后,往往会粘在上面,粘壁的物料由于长时间停留在内壁上,有可能会烧糊或者变质,影响产品质量;而且粘壁后的物料经常会结块落入塔底出料口,使产品有时达不到规定的湿含量和细度,为此,我们提出一种利用惰性气体带走生成蒸气的装置。The existing spray dryer is a kind of equipment that uses inert gas to dry. It uses an atomizer to disperse the material liquid into droplets, and uses hot gas to dry the droplets to obtain products. The main working process is: fresh air from the outside passes through the air filter 1. The blower enters the air heater to increase the air temperature to about 160°C, and then sends it into the drying tower. Before entering the drying tower, the hot air passes through the uniform wind plate to make the hot air evenly distributed, prevent vortex, and avoid coke powder. In order to ensure the drying effect. The material liquid to be dried is pumped to the atomizer by the pressure pump, the material liquid is sprayed out in the form of mist and mixed with hot air, the material particles absorb heat, the water evaporates instantly, and the powder is formed and falls downward. After a period of constant speed drying, The water is further evaporated, and the coarse particles fall into the bottom of the drying tower and are discharged. The mixture of dried material fine powder and low-temperature humid air is separated by the cyclone separator, the waste air is discharged by the exhaust fan, and the dry fine powder product falls by the unloader. Continuous discharge, when the spray dryer is working, the wet material will stick to it after being thrown onto the wall of the drying tower, and the material sticking to the wall may burn or deteriorate due to staying on the inner wall for a long time, which will affect the quality of the product ; And the material after sticking to the wall will often agglomerate and fall into the discharge port at the bottom of the tower, so that the product sometimes cannot reach the specified moisture content and fineness. Therefore, we propose a device that uses inert gas to take away and generate steam.
