Abstract
Description
Technical Field
[0001] The utility model relates to a steam inlet pressure control structure for a single alcohol distillation tower, belonging to the technical field of alcohol production. Background Art
[0002] When the SD800 single-tower alcohol distillation tower is in operation, industrial steam is regulated by a pneumatic diaphragm valve and then enters the tower bottom to heat the alcohol. Because the pneumatic diaphragm valve uses a range-type pressure regulation method, the industrial steam pressure entering the tower is unstable, often experiencing delays. This unstable industrial steam pressure can lead to unstable temperature control in various zones within the tower, resulting in unstable and fluctuating production capacity for recovered finished alcohol. This not only reduces the recovery rate of the single-tower alcohol distillation tower, but also results in substandard recovered alcohol concentration, which is discharged into the waste alcohol tank, resulting in unnecessary waste of water, electricity, gas, and steam. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a single-tower steam inlet pressure control structure for alcohol distillation.
[0004] The utility model is achieved through the following technical solutions:
[0005] A steam inlet pressure control structure for an alcohol distillation single tower comprises an alcohol distillation single tower, an industrial steam pipe and a controller, wherein the industrial steam pipe is connected to an air inlet at the lower portion of the alcohol distillation single tower, the industrial steam pipe is provided with a real-time air pressure regulating component and an air pressure detection component, and the air pressure detection component is located between the real-time air pressure regulating component and the alcohol distillation single tower, and the controller is electrically connected to the real-time air pressure regulating component and the air pressure detection component.
[0006] The real-time air pressure regulating component is a PID pneumatic regulating valve.
[0007] The air pressure detection component is a pressure sensor.
[0008] The industrial steam pipe is provided with a valve, and the real-time air pressure regulating component and the air pressure detecting component are both located between the valve and the alcohol distillation single tower.
[0009] The valve is a stop valve.
[0010] The valve is electrically connected to the controller.
[0011] A touch screen is also included, and the touch screen is electrically connected to the controller.
[0012] The beneficial effects of the present invention are that the real-time air pressure regulating component will adjust the pressure of the industrial steam in time according to the pressure set by the controller without any delay, so that the pressure of the industrial steam entering the bottom of the tower tends to be stable, ensuring that the temperature of each area in the alcohol distillation single tower is stable without large deviations, ensuring the stability of the production capacity of the alcohol distillation single tower without fluctuating highs and lows, thereby improving the recovery rate of the alcohol distillation single tower, ensuring that the recovered alcohol concentration meets the quality requirements, and effectively controlling energy consumption to achieve energy conservation and emission reduction.

The through-hole controller 5 sets the industrial steam pressure value or the pressure control program. When the SD800 alcohol distillation single tower 1 is running, the real-time air pressure regulating component 3 automatically adjusts the pressure of the industrial steam according to the industrial steam pressure value or the pressure control program set by the controller 5. At the same time, the industrial steam pressure adjusted by the air pressure regulating component 3 is detected by the air pressure detection component 6 and transmitted to the controller 5 to realize closed-loop control of the industrial steam pressure. Then the industrial steam enters the bottom of the alcohol distillation single tower 1 to heat the alcohol. When the bottom of the tower needs to be heated or cooled, the real-time air pressure regulating component 3 will adjust the pressure of the industrial steam in time according to the pressure set by the controller 5 without any delay, so that the pressure of the industrial steam entering the bottom of the tower tends to be stable, ensuring that the temperature of each area in the alcohol distillation single tower 1 is stable without large deviations, ensuring that the production capacity of the alcohol distillation single tower 1 is stable, and there is no fluctuation, thereby improving the recovery rate of the alcohol distillation single tower 1, ensuring that the recovered alcohol concentration meets the quality requirements, and effectively controlling energy consumption to achieve energy saving and emission reduction.
