| titleOfInvention | Rectifying tower for separating and recovering acetone in acetone-azine hydrolysis waste liquid |
| abstract | The utility model provides a rectifying column of acetone in acetone continuous nitrogen hydrolysis waste liquid is retrieved in separation, includes tower body, separator, and the big footpath section bottom of tower body is equipped with row material pipe, and the lateral wall is equipped with the inlet pipe, and the top of path section is equipped with the blast pipe, and separator includes the distributor, packs, tower tray, and the distributor is located the path section of tower body, and the tower tray setting is located the top of inlet pipe in the big footpath section of tower body, packs to set up in the big footpath section of tower body, is located the top of tower tray. The utility model discloses simple structure, maintenance convenience for acetone azino method hydrazine hydrate waste liquid recovery system of hydrolysising, its effect is retrieve acetone and separation isopropanol and its derivative, and can effectively avoid the pressure drop rising phenomenon that high polymer adhesion such as pyrazoline, ketone high polymer arouses, guarantees the long-time normal operating of rectifying column. |
