The invention relates to a recycling device after carbon tetrachloride is used for cleaning oil stains on a cold rolled tube. The recycling device comprises a heater, a conveying tube, a condenser and a liquid storage tank, wherein the heater consists of a liquid storage barrel and a heating tube, the heating tube is arranged at the bottom end inside the liquid storage barrel, a steam outlet is formed in the top end of the liquid storage barrel, and a liquid filing hole is formed in the upper end of the left side of the liquid storage barrel; the condenser consists of a condensing barrel and a condensing tube, the condensing tube is arranged in the condensing barrel, a liquid inlet is formed in the top end of the condensing barrel, and a liquid outlet is formed in the bottom of the condensing barrel; the heater is communicated with the condenser through the conveying tube, the conveying tube is arranged at the lower end of the liquid outlet of the condenser, and the liquid storage tank is arranged above the conveying tube at the lower end of the liquid outlet of the condenser. The recycling device has the benefits that recycled carbon tetrachloride liquid can be used as a cold rolled tube oil cleaning agent again, so that a large amount of raw materials is saved, and the production cost is reduced; the recycling device is simple and convenient and has low requirements for operation personnel.
Description
technical field [0001] The invention relates to a cold-rolled pipe oil cleaning agent recycling device, in particular to a carbon tetrachloride waste liquid recycling device for cleaning cold-rolled pipe oil. Background technique [0002] During the cold-rolling process of the steel pipe, cold-rolled grease is attached to the inner and outer surfaces of the cold-rolled pipe, and the cold-rolled grease needs to be preliminarily cleaned during the production process. At present, kerosene is used as a cleaning agent. Although the degreasing effect is better, kerosene is a kind of flammable oil, which is easy to cause a fire. In order to overcome the deficiency of kerosene degreasing. The applicant innovatively uses carbon tetrachloride as a degreasing liquid to degrease cold-rolled steel pipes, which not only has a good degreasing effect, but is also safe and reliable. Since the degreasing performance of carbon tetrachloride is similar to that of acetone, the degreasing effect...
