一.二氧化硫發生器制造二氧化硫和亞硫酸鈉的主要裝置是一个二氧化硫發生器(如图1)。它是用一个腹部横截面直徑为11厘米的酒瓶,截去下半部,留着長約14厘米的上半段作为玻璃盅罩(圖1a),把它固定在木板b上,在玻璃盅罩內木板中央置一燃硫铁皿c,將一根玻璃管穿通木板b和燃硫鉄皿c的中央,玻璃管的下端和吹 I. Sulfur dioxide generator The main device for making sulfur dioxide and sodium sulfite is a sulfur dioxide generator (Figure 1). It is a wine bottle with an abdominal cross-section of 11 cm in diameter cut off the lower half, leaving the upper half of the length of about 14 cm as a glass cover (Figure 1a), it is fixed on the wood b The center of the cup cover placed a pyrite pyrolysis dish c, a glass tube through the wood b and sulfur C u dish c, the lower end of the glass tube and blowing
