电石灯又名乙炔灯或嘎斯灯,它是采用工业电石作为原料,电石加水产生乙炔。纯净乙炔是不具任何气味的可燃性气体,但是一般工业用的乙炔,具有一种非常强烈的臭味,这是因为有杂质——磷化氢(PH_3)、硫化氢(H_2S)或砷化氢 (AsH_3)存在。这些杂质是有毒的,施工作业人员暂短的接触会有轻度中毒、长期接触会严重的影响健康。为了保障作业人员的健康,在技术革新运动中,我们针对着这些情况将原来的电石灯作了一些改进。(一)改进原理:1.工业用电石中普通含有磷化钙(C-a_3P_2)或砷化钙(Ca_3As_2),这些物质当碳 Calcium carbide lamp, also known as acetylene lamp or lights, it is the use of industrial calcium carbide as raw material, calcium carbide water to produce acetylene. Pure acetylene is a non-flammable, flammable gas, but acetylene, which is commonly used in industry, has a very strong odor due to impurities such as phosphine (PH 3), hydrogen sulfide (H 2 S) or arsine (AsH_3) exists. These impurities are toxic, and temporary contact with construction workers can cause mild poisoning. Long-term exposure can seriously affect health. In order to protect the health of workers, we have made some improvements to the original carbide lamps in the technological innovation movement. (A) the principle of improvement: 1. Industrial calcium carbide commonly contain calcium phosphide (C-a_3P_2) or calcium arsenide (Ca_3As_2), these substances when the carbon
