SU916530A1 - Method for controlling electrical ignition of charge - Google Patents

Description

The invention relates to methods for controlling the process of electric burner charge and can be used in the coke chemical and chemical industry.

Known method implemented Device for ⁵ roystvom process control elektropodzhoga charge. According to this method, electro-electric is controlled by acting on the supply of electric potential (through the rod to the charge) by current jump in the potential supply circuit [1].

The disadvantage of this method is the possibility of false alarms ^{15 of the} system.

There is also known a method implemented by a device for automatic control of the process of electric burner of a charge. Electrical burns are controlled by influencing the supply of electric potential by the temperature change in the arson zone [2].

The disadvantage of this method is; I have a limited service life of the case of the thermal sensor, since the cover quickly collapses under conditions of high temperatures and a chemically aggressive environment: an exothermic redox process is intensively carried out during arson; this leads to frequent downtime of the furnace (apparatus) due to the need to replace the sensor; contamination of the ignited charge with a substance of a collapsing cover, reducing. quality of the product; the presence of a certain time interval from the moment of actual arson of the charge to the moment of the corresponding working out of the system fixing the arson; it also leads to loss of useful time, downtime.

The purpose of the invention is to increase the yield and quality of the product.

This goal is achieved by the fact that the impact on the supply of electric potential is carried out by the pressure 3 916530

the generation of gases, which determine the time of the completion of arson.

The drawing shows a block system of a device for implementing the proposed method.

The device contains an electrocontact - a stroke manometer 1, a block 2, an electric drive 3 of the electrode 4, a transformer 5 and an actuator 6 in the electric circuit of the arson.

The device works as follows.

From the moment the signal arrives, “On arrival of the signal of arson,” commands from block 2 to rod 4 are driven back and forth by drive 3, and simultaneously starter 6 is turned on: the potential from transformer 5 is applied to the arson circuit.

As a result of the electric arc effect, the mixture is burned, the pressure in the apparatus increases rapidly. The signal. From the electric contact gauge 1, the unit 2 generates commands to stop the rod 4 in the extreme upper position and the removal of the arson potential by disconnecting the starter 6.

If necessary, block 2 may include an alarm signaling the end of arson and issue a command to conduct the next process operation.

Depending on the implementation technology of the proposed control method in one workshop, an economic effect of 20-45 thousand rubles per year can give.

Claims (1)

Claim The method of controlling the electric burn-in process of the charge by acting on the supply of electric potential, is tactile in that, in order to increase the yield and quality of the product being produced, the effect on the supply of electric potential is realized by the pressure of the resulting gases, which determine the moment complete arson.
