1.铝合金压铸废气概述
1. Overview of waste gas from aluminum alloy die casting
铝合金在压铸工序中会产生含硫和含氮的尾气,也会排放出大量的颗粒物,其中包括粉尘和黑烟。铝合金压铸废气温度高、带有腐蚀性,尾气溶于水呈酸性,这些污染物会影响工厂车间员工工作环境,还会破坏周边的环境,造成大气污染。
Aluminum alloy in the die casting process will produce sulfur-containing and nitrogen-containing exhaust gas, but also will emit a large number of particles, including dust and black smoke. The exhaust gas of aluminum alloy die casting has high temperature and corrosiveness. The exhaust gas dissolves in water and is acidic. These pollutants will affect the working environment of employees in the factory workshop and damage the surrounding environment, causing air pollution.

2. Treatment method of waste gas from aluminum alloy die casting
根据铝合金压铸废气的主要特点是,高温,带有腐蚀性,溶于水呈酸性,处理铝合金压铸废气可以选择喷淋塔对其进行净化处理。由于铝合金压铸废气的性质,所以在处理铝合金压铸废气时,应考虑喷淋塔的耐腐蚀性和耐高温性、根据天浩洋20多年的废气处理经验,需要使用不锈钢材质作为喷淋塔外壳才可抵御铝合金压铸废气的高温和腐蚀性。
According to the main characteristics of aluminum alloy die casting waste gas, it is high temperature, corrosive, soluble in water and acidic. Spray tower can be selected to purify aluminum alloy die casting waste gas. Due to the nature of the waste gas from aluminum alloy die casting, the corrosion resistance and high temperature resistance of the spray tower should be considered when dealing with the waste gas from aluminum alloy die casting. According to the waste gas treatment experience of tianhaoyang for more than 20 years, stainless steel is needed as the shell of the spray tower to resist the high temperature and corrosion of the waste gas from aluminum alloy die casting.

喷淋塔是由填料层、喷淋层、喷淋层、除雾层等多个组件组成,所有组件均由不锈钢材质制成。铝合金压铸废气从塔底进入废气喷淋塔内,顶部喷嘴喷出吸收液,吸收液在填料层的鲍尔环填料形成液膜,废气与液膜接触发生化学反应,达到净化的效果。废气继续上升通过后续的多层的填料层进行净化处理,最后通过除雾层干燥并实现达标排放。
Spray tower is composed of packing layer, spray layer, spray layer, demist layer and other components, all components are made of stainless steel. The waste gas of aluminum alloy die casting enters into the waste gas spray tower from the bottom of the tower, and the absorption liquid is sprayed from the top nozzle. The absorption liquid forms a liquid film on the Bauer ring packing of the packing layer, and the chemical reaction occurs between the waste gas and the liquid film to achieve the purification effect. The waste gas continues to rise, and is purified through the subsequent multi-layer packing layer. Finally, the waste gas is dried through the demisting layer and discharged up to the standard.

(1)根据企业的实际情况,可以选择多种不同的吸收液对铝合金压铸废气进行处理。
(1) According to the actual situation of the enterprise, a variety of different absorption liquid can be selected to treat the waste gas of aluminum alloy die casting.
(2)喷淋塔处理工艺简单且成熟,全自动化操作,无需人工看管。适用于持续性和间歇性生产,对车间生产不造成影响。
(2) Spray tower treatment process is simple and mature, fully automatic operation, without manual care. It is suitable for continuous and intermittent production and has no influence on workshop production.
(3)填料采用高效、低阻力的鲍尔环填料,可有效地净化铝合金压铸废气,清洗后可反复使用。
(3) The ball ring packing with high efficiency and low resistance can effectively purify the waste gas of aluminum alloy die casting, and can be used repeatedly after cleaning.
