Description
TECHNICAL FIELD
[0001] The utility model belongs to the field of chemical production technology, and concretely relates to a cleaning device for GBL production. BACKGROUND
[0002] 1,4-butyrolactone, also known as gamma-butyrolactone and GBL, is an organic compound with the chemical formula C4H6O2 and a molecular weight of 86.089. It is a colorless transparent liquid and is used to produce pharmaceuticals such as cyclopropylamine and pyrrolidone. It can also be used as an industrial solvent, diluent, curing agent, etc., and is classified as a third-class controlled chemical.
[0003] Currently, the production of 1,4-butyrolactone mainly uses 1,4-butanediol as the raw material. The 1,4-butanediol is first preheated and then reacted with hydrogen in the presence of a copper catalyst at a temperature of 230-240°C to obtain 1,4-butyrolactone crude product, which is then distilled under reduced pressure to obtain the product. Alternatively, 1,4-butanediol is reacted with a strong acid catalyst such as sulfuric acid to produce 1,4-butyrolactone and water, which is then purified by distillation to obtain the product.
[0004] After production is completed, the reaction device, such as the mixing tank, needs to be cleaned. The existing cleaning method generally uses manual cleaning, in which workers hold a water gun nozzle to flush the inside of the tank. However, 1,4-butyrolactone itself has slight toxicity, and during the flushing process, it is inevitable that 1,4-butyrolactone will splash onto the workers' clothes or exposed skin, causing harm to the human body. In addition, due to the heavy weight of the mixing tank, manual cleaning is laborious, and there are problems of high labor intensity and low work efficiency.
