三乙胺对环境的主要影响：
Three main effects of ethylamine on the environment:
1）三乙胺又名三乙基胺，分子式为C6H15N，三乙胺属大气中有害污染物。美国政府将其列入新清洁空气法（Clean Air Act）中189种优先控制的大气有害污染物之一[2]。
1) three ethylamine, also known as three ethylamine, has a molecular formula of C6H15N, and three ethylamine is a harmful pollutant in the atmosphere. The United States government listed it as one of the 189 priority air pollutants in the Clean Air Act, [2].
2）三乙胺具有强烈的氨臭味、有刺激性、易燃、易挥发。50ppm浓度的三乙胺就可使人产生严重的肺刺激症状[3]。
2) three ethylamine has strong ammonia odor, irritating, flammable and volatile. 50ppm concentration of three ethylamine can cause severe lung irritation symptoms [3].
三乙胺废气处理设备工作原理：由于三乙胺废气呈碱性，因此采用磷酸与其发生中和反应生成三乙胺磷酸盐，达到净化作用。化学方程式为：（CH3CH2）3N＋H3PO4→（CH3CH2）3N•H3PO4<三乙胺磷酸盐>。因三乙胺在水中的溶解度大，经过充分的实践，选用2%－4%的喷淋状态下的稀磷酸溶液为中和吸收液，处理效果最佳。
Three ethylamine waste gas treatment equipment working principle: because three ethylamine waste gas is alkaline, so the use of phosphoric acid and the reaction to produce three ethylamine phosphate, to achieve purification. The chemical equation is: (CH3CH2) 3N + H3PO4 > (CH3CH2) 3N? H3PO4< three ethylamine phosphate >. Because the solubility of three ethylamine in water is great, after full practice, the solution of 2% to 4% of the dilute phosphoric acid under the spray state is selected as the neutralization absorption solution, and the treatment effect is the best.
处理三乙胺废气工艺流程，整个系统在风机的动力作用下，通过吸尘罩及管道将冷芯盒射芯机内及其周围的废气收集进入均压箱均压后，再进入砂尘分离器去除砂粒和其它异物，出气再经过净化塔内布气器均匀进入塔内，与通过喷淋装置产生的二道逆流磷酸酸雾充分接触，发生化学反应。净化塔内的磷酸酸液充分吸收了废气，去除三乙胺废气，净化后的气体向上，进入塔体上部以填料球组成的脱液层脱去水份后经烟囱排入大气。
The process flow of three ethylamine waste gas is treated. The whole system, under the power of the fan, collects the exhaust gas in the core box and around the cold core box and enters the pressure box, then enters the sand dust separator to remove the sand and other foreign objects, and then purify the Taneb gas device and enter the tower evenly. The two countercurrent phosphoric acid mist produced by the spray device is fully exposed to chemical reaction. The phosphoric acid in the purifying tower fully absorbs the waste gas and removes the waste gas of three ethylamine. The gas after the purification goes up to the upper part of the tower to remove the water from the deliquid layer, which is made up of the packing ball, and then into the atmosphere through the chimney.
