The utility model relates to condenser technical field especially is concerned with a kind of acetone condenser, including condensing shell and cooling liquid pipeline, condensing shell top surface is equipped with the acetone steam inlet pipe for supplying acetone, condensing shell bottom surface is equipped with the acetone liquid outlet pipe for supplying acetone liquid outflow;Cooling liquid pipeline includes cooling liquid inlet pipe, cooling liquid outlet pipe, shunt main pipe, several cooling pipes, several connecting pipes and several shunt branch pipes, cooling pipe transversely passes through condensing shell, shunt main pipe and cooling liquid inlet pipe are connected, shunt branch pipe one end and shunt main pipe are connected, other end and the connecting pipe of the side where cooling liquid inlet pipe is located are connected, shunt branch pipe diameter is less than cooling pipe diameter, multilayer cooling pipe cooperates fin and greatly increases heat exchange area, improves condensing efficiency in limited space;Shunt branch pipe ensures that cooling liquid is evenly distributed to each layer pipeline, avoids local overheating.

The application discloses a kind of self-circulation cooling device for air compressor, the air compressor includes static scroll and dynamic scroll, and a set of cooling structure is respectively arranged outside two scrolls;Each set of cooling structure includes multiple horizontal radiators, the import end of multiple horizontal radiators is gathered on a import longitudinal radiator, the export end of multiple horizontal radiators is gathered on a export longitudinal radiator, the inside of horizontal radiator is provided with three layers of cavities from inside to outside, three layers of cavities are in turn from inside to outside as inner cavity, intermediate cavity and outer cavity, the both ends of intermediate cavity are sealed to form closed cavity and are filled with acetone liquid, the import end of inner cavity and the import end of outer cavity are respectively connected with the water cavity of import longitudinal radiator, and the export end of inner cavity and the export end of outer cavity are respectively connected with the water cavity of export longitudinal radiator.The advantages of the present application: while reducing the volume of cooling device, the cooling effect is guaranteed.

The invention belongs to the technical field of electronic-grade acetone purification, and particularly relates to an electronic-grade acetone purification system which comprises an acetone tower vacuum buffer base, the acetone tower vacuum buffer base is placed on the ground, a first vacuum buffer mechanism is installed at the top of the acetone tower vacuum buffer base, and the first vacuum buffer mechanism is externally connected with an acetone temporary storage tank. The acetone temporary storage tank conveys pretreated acetone raw materials into the first vacuum buffer mechanism, the first vacuum buffer mechanism conducts vaporization, upward drainage and collection operation on the acetone raw materials, full-coverage online cleaning of impurities on the inner wall of the conical cylinder is achieved, shutdown is not needed, and the inner wall of equipment is not damaged; secondary vaporization recovery of scraped liquid drops and separation strengthening of high-impurity raw materials are synchronously completed, and the defects that existing equipment cannot be cleaned online, the continuous operation period is short, the acetone liquid drop entrainment loss is large, the raw material recovery rate is low, and the inner surface of the equipment is prone to being damaged by a cleaning device are overcome.

The utility model provides a metering tank for acetone, which comprises a metering tank, a feeding pipe is arranged at the top of the metering tank, a discharging pipe is arranged at the bottom end of the metering tank, a filter screen with the middle part protruding upwards is arranged in the metering tank, a motor is arranged on the metering tank, and the motor is connected with the metering tank. A cleaning brush of an inverted-V-shaped structure is fixedly connected to an output shaft of the motor, and a discharging hole is formed in the position, at the filter screen, of the side wall of the metering tank. The acetone liquid metering device has the advantages that acetone liquid is input into the metering tank through the feeding pipe, and the acetone liquid is filtered by the filter screen, so that impurities are blocked. According to needs, the motor is started to drive the cleaning brush to rotate, the cleaning brush rotates to drive impurities on the filter screen to slide around, and the impurities penetrate through the discharging holes to enter the collecting frame. According to needs, the collecting frame is taken out of the mounting frame, and impurities in the collecting frame are cleaned. The influence of impurities on the metering accuracy can be avoided, the impurities can be conveniently removed from the filter screen, and the practicability is higher.
