The main equipment of sieve plate distillation experimental device for the sieve plate tower, a total of 10 tower plate made of stainless steel plate, tower height 1.5 meters, tower body with inner diameter of 50 mm stainless steel pipe, each section is 10 cm, welded flange, with bolts together, and pad on the polytetrafluoroethylene pad leakproof, the second section and the ninth section of the tower is made of heat-resistant glass, in order to observe the tower The operating condition in.

The main equipment of sieve plate distillation experimental device for the sieve plate tower, a total of 10 tower plate made of stainless steel plate, tower height 1.5 meters, tower body with inner diameter of 50 mm stainless steel pipe, each section is 10 cm, welded flange, with bolts together, and pad on the polytetrafluoroethylene pad leakproof, the second section and the ninth section of the tower is made of heat-resistant glass, in order to observe the tower The operating condition in. Except for these two glass tower sections, the rest of the tower sections are insulated with glass wool. The downdraft pipe is made of stainless steel pipe with an outside diameter of 8 mm. The diameter of the sieve plate is 54 mm and the diameter of the sieve hole is 2 mm. A platinum resistance thermometer is installed in the tower to measure the vapor phase temperature in the tower.

Inside the tower top condenser and bottom cooler of the sieve plate distillation experimental device are stainless steel tubes with a diameter of 8 mm made of spiral, and outside are stainless steel bushings. Tower steam and tower bottom products in the stainless steel pipe condensation, cooling, stainless steel pipe through cooling water. The tower kettle is heated with electric furnace wire, and the outside of the tower is also insulated with thermal insulation cotton.

The mixed liquid enters the tower from the storage tank through the feed pump through the direct feed valve (measured by the high slot rotor flowmeter). The level meter of the tower kettle is used to observe the amount of liquid stored in the tower kettle. Tower bottom products through the cooler from the balance pipe. The reflux ratio regulator is used to control the reflux ratio and the distillate storage tank receives the distillate.

The control of reflux ratio of sieve plate distillation experimental device is realized by means of electromagnet drawing pendulum needle. Reflux ratio can be controlled by programming the on-off time in the computer.
