溧阳酸碱废气喷淋塔-适用范围:炼油厂、橡胶厂、皮革厂、印刷厂、化工厂、中西药厂、金属铸造厂、塑料再生厂、喷涂溶剂、食品加工厂、肉类加工厂、屠宰场、家禽饲料场、造纸厂、污水处理厂、垃圾转运站等有机和无机物废气净化处理。
填料式喷淋塔工作原理如下:
填料式喷淋塔是在喷淋塔中填充不同形式的填料,将喷出的水转变为附着在填料上的水膜,从而增强气与水的接触面,这种净化器特别适合用于含有油漆颗粒物的废气。在喷淋塔中,废气从塔下部进入,经过填料表面与水膜充分接触。塔内设置数排喷嘴,水雾在重力作用下向下运动,与废气气流方向相反,废气气流经水雾净化后向上排出,在气体排出之前设除水层将气流中的水滴捕集下来,防止带出。
废气经水雾捕集后进入循环水箱,经过沉淀及隔渣处理后循环使用。由于废气在洗涤过程会有部分物质溶解于水中,使得循环水在长期运行后达到饱和状态。此时应排掉部分循环水,并向水池中补充部分新鲜水,以使循环水保持一定的吸收能力。更换后的废水可由专门回收机构回收,真正实现零排放,不会对水体产生二次污染。
特点
1.设备占地少,安装方便;
2.耗水、耗电指标较低;
3.耐腐蚀、不磨损,使用寿命长;
4.设备运行可靠,维护简单、方便。
结构
喷淋塔内填料层作为气液两相间接触构件的传质设备。填料塔底部装有填料支承板,填料以乱堆方式放置在支承板上。填料的上方安装填料压板,以防被上升气流吹动。喷淋塔喷淋液从塔顶经液体分布器喷淋到填料上,并沿填料表面流下。气体从塔底送入,经气体分布装置分布后,与液体呈逆流连续通过填料层的空隙,在填料表面上,气液两相密切接触进行传质。当液体沿填料层向下流动时,有时会出现壁流现象,壁流效应造成气液两相在填料层中分布不均,从而使传质效率下降。因此,喷淋塔内的填料层分为两段,中间设置再分布装置,经重新分布后喷淋到下层填料上。
适用注意事项
1、喷淋塔沉淀池要经常清理,夏天一周清理一次。
2、各转动部件要经常检查、注油,发现故障要及时排除,以保证喷淋塔脱硫效果。
3、在上、下楼梯加药时要注意安全,要有自主保安,相互保安意识。
4、工作完毕要及时清理好卫生,做到人走场地清。
Application of the Liyang waste gas spray tower - scope: refinery, rubber factory, leather factory, printing factory, chemical factory, Chinese pharmaceutical factory, metal foundry, plastics recycling plant, spraying solvent, food processing plants, meat processing plants, slaughterhouses and poultry feed, paper mill, sewage treatment plants, garbage transfer stations etc. organic and inorganic waste gas purification. The working principle of packed spray tower is as follows: Filler type spray tower is filled with different forms of filler in the spray tower, turning water spray for attached water film on the packing, so as to enhance the contact surface of gas and water, the purifier is especially suitable for exhaust gas containing paint particles. In the spray tower, the exhaust gas enters from the lower part of the tower and is fully contacted with the water film through the packing surface. The tower set the number of rows of nozzles, spray downwards under the action of gravity, in contrast with the exhaust gas flow direction, exhaust air flow through the mist purification to discharge in gas discharge in water will be set before the air drops of water in the trap down, to prevent out of. The exhaust gas enters into the circulating water tank after the water mist is collected, and then is used after the precipitation and the slag separation treatment. As the waste gas in the washing process will be part of the material dissolved in water, so that the circulation of water in the long run after saturation. At this point should be part of the circulation of water, and to add some fresh water to the pool, so that the circulation of water to maintain a certain degree of absorption. After the replacement of waste water can be recovered by the special recycling agencies, truly zero emissions, water pollution will not produce two times. Characteristic 1 equipment area is small, easy to install; 2 water consumption, low power consumption indicators; 3 corrosion resistance, no wear, long service life; 4 the equipment is reliable and easy to maintain. structure The spray tower filler layer as a component of gas-liquid two phase contact mass transfer equipment. The packing tower with packing support plate, packing to huddle place in the support plate. The filler is installed above the filler plate, in order to prevent rising air blowing. Spray tower spray liquid from the top of the tower by spraying liquid distributor to packing, and the packing surface along the flow. The gas is fed from the bottom of the tower, and is distributed with the liquid through the gas distribution device, and then flows through the gap of the packing layer. When the liquid flows along the packing layer, the wall flow phenomenon sometimes occurs, and the wall flow effect results in the uneven distribution of the gas-liquid two-phase in the packing layer, which leads to the decrease of the mass transfer efficiency. Therefore, the filler layer spray tower is divided into two sections, arranged in the middle of distribution device, the re distribution of spray to lower packing. Matters needing attention 1, spray tower sedimentation tank to be cleaned regularly, clean up once a week in summer. 2, the rotating parts should always check the oil, and found that failure to promptly eliminate, to ensure the effect of desulfurization spray tower. 3, in the upper and lower stairs when medicine is to Caution!, have independent security, mutual security awareness. 4, the work is completed in a timely manner to clean up the health, so that people go to the venue.
