Description

Solvent discharger

Technical Field

The utility model belongs to the technical field of raw material medicine production, and particularly relates to a solvent discharger.

In the field of drug substance production, various organic solvents with strong volatility are needed in the drug substance production process, such as: methanol, ethanol, hydrochloric acid, ammonia water and the like, and in the transfer process, if the operation is open, the operation is harmful to people and the environment. In the production of bulk drugs, acid-base organic waste liquid is generated by centrifugation, layering, resin activation, distillation and the like, and the waste liquid is required to be transferred to a designated position for disposal through a ton barrel.

At present, a hose is used for discharging organic waste liquid into a ton barrel, and organic volatile gas enters the ton barrel along with feed liquid and escapes into the air from a ton barrel opening to pollute the environment, and the organic volatile gas usually contains harmful substances such as organic acid, ester, alcohol and the like, and the substances can pollute the environment. If these gases are vented to the atmosphere, they can also adversely affect the quality of the air and the slightly inadvertent acidic and basic liquids can splash onto the operator's skin during the transfer process. If the organic volatile gases are not properly treated, they may contaminate the feed solution, thereby affecting the quality of the final product. It is also easy to cause the product to be out of specification and standard with serious consequences.
