Embodiment Construction

[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] see figure 1 Shown is an ignition control method 10 for a spray granulation tower burner, the specific steps of the ignition control method are:

[0028] 11. After the controller starts the fuel injection pump motor and the ignition transformer in sequence, it opens the primary oil supply solenoid valve to make the burner enter the ignition state;

[0029] 12. Detect the ignition state of the burner by the photosensitive detector, if the ignition is successful, directly perform step 15;

[0030] 13. The controller performs the second ignition control, that is, closes the primary fuel supply solenoid valve and then opens the primary fuel supply solenoid valve again, and detects the ignition status of the burner by the photosensitive detector. If the ignition is successful, directly execute step 15;

[0031] 14. The con...

Abstract

The invention discloses an ignition control method for a spray granulation tower burner and an ignition control device. The ignition control device comprises a controller, a primary oil supply electromagnetic valve, a secondary oil supply electromagnetic valve, an oil spray pump motor, an ignition transformer and a photosensitive detector. Firstly, the controller sequentially turns on the oil spray pump motor and the ignition transformer, then, the primary oil supply electromagnetic valve is opened so that the burner enters at most twice ignition state, when the ignition is successful, the controller opens the secondary oil supply electromagnetic valve, then, the ignition transformer is turned off, and the secondary oil supply electromagnetic valve and a hearth temperature compensation unit of the spray granulation tower form a temperature closed loop control loop. When the ignition is not successful, the controller closes the primary oil supply electromagnetic valve and the secondary oil supply electromagnetic valve and turns off the oil spray pump motor, and in addition, a fault indicating lamp illuminates.

Description

technical field [0001] The invention relates to a burner ignition technology for a spray granulation tower, and more particularly relates to an ignition control method and a device for a spray granulation tower burner. Background technique [0002] The spray granulation tower is a device used to heat and dry the powdery raw materials for the production of magnetic materials to form granular materials and enter the next production process. The process of the spray granulation tower is as follows: diesel oil is burned in the combustion chamber through the burner, and then the high-temperature gas is sent to the spray granulation tower, and the magnetic material is heated and baked for a certain period of time to make the magnetic material The material is formed into granules and sent to the next process as a semi-finished product. Only when the burner adopts the continuous combustion method can the temperature required by the production process be maintained in the spray gran...
