Abstract
The utility model relates to a heater control device used for diphenylamine production. The device is characterized in that the device comprises a temperature controller, a cycle controller, a trigger driving board and a main loop of an electric furnace heater which are successively connected; a current chain relay KA1 and a temperature chain relay KA2 are connected in series between the cycle controller and the trigger driving board; a signal receiving end of a DCS control system is connected with an amperemeter signal output terminal of the main loop of the electric furnace heater; a control signal output terminal of the DCS control system accesses to the cycle controller; the control signal output terminal of the DCS control system is connected with the current chain relay KA1 and the temperature chain relay KA2. A detection current of the amperemeter of the main loop of the electric furnace heater is sent to the DCS control system. The DCS control system timely changes the current of the main loop of the electric furnace heater. The current chain relay KA1 and the temperature chain relay KA2 can timely be cut off under the conditions that the electric furnace current is too large, is in a short circuit state or a temperature is too high and so on.
