SU152425A1 - The method of automatic control and regulation of the drying process - Google Patents

Description

The invention relates to methods for automatically controlling and regulating the drying process of various chemicals, building structures and industrial units, such as electric machines, furnaces, etc., by measuring the humidity of the drying agent.

Measurements of the moisture content of the drying agent before and after the object of drying or the value of the values that are in one dependence on this difference are measured (the product of the difference in moisture content and the consumption of the drying agent, the integral of the time from this plot, etc.).

Such a drying method provides for obtaining continuous information on the amount of moisture removed from the drying object, and using this information as input signals from automatic control systems.

The drawing shows a block diagram of the device for drying the proposed method.

A drying agent is supplied to the object / drying with the aid of the fan 2, the humidity of which at the entrance to the object is measured by the sensor 3, and at the output of the object by the sensor 4.

The 3 II 4 humidity sensors are connected to the device 5. measuring the difference in moisture content of the drying agent before and after the object / drying.

The device 6 measures the flow rate of the drying agent that has passed through the object 1, and the devices 7 and 8 measure the magnitude of w.xc in an unambiguous manner depending on the difference in moisture content of the drying agent before and after the object of drying defined by the device 5 (product

differences in moisture content on the consumption of the drying agent, the time integral of this product, and others.)

Instruments 5, 6, 7, and 5 are used both to obtain continuous information on the amount of moisture removed from the drying object, and-C: as input signals from automatic control systems of the drying process.

Subject invention

A method for automatically congruing and controlling the drying process of various materials, building structures and industrial units, such as electric machines, furnaces, etc., by measuring the moisture of the drying agent, that is, with and without The purpose of obtaining continuous information on the amount of moisture removed from the drying object, and using this difference as input signals of automatic control systems, is measured the difference in moisture content of the drying agent before and after the drying object or the value of ahod br, ihs in an unambiguous function of this difference (the difference of the product flow moisture content of the drying agent, the time integral of the product of this and others.).
