Embodiment 1
[0013] (1) Connect the power supply of the engine or car battery to the electronic control PLC to provide power, and the electronic control PLC supplies power to the PID. The temperature sensor on the catalytic muffler purifier sets the emission national standard temperature value and provides the CAN signal to the PID. The PID controls the entire rear Handle the circulatory system, the system starts to run after power on;
[0014] (2) Connect compressed air to the Tianlan tank, depressurize through the pressure-reducing solenoid valve and pressure controller to form a micro-pressure, and input the urea liquid into the ultrasonic atomization studio through the pipeline; the ultrasonic atomization studio is designed with a twist cap or The cover is fastened by screws, and a liquid level controller, an ultrasonic atomizer, and a flow meter are installed inside;
[0015] (3) The urea liquid is ultrasonically atomized in the ultrasonic atomization studio and enters the catalytic n...
Embodiment 2
[0018] (1) Connect the external power supply of the kiln to the electric control PLC to provide power, and the electric control PLC supplies power to the PID. The temperature sensor on the catalytic muffler purifier sets the discharge national standard temperature value and provides the CAN signal to the PID. The PID controls the entire rear Handle the circulatory system, the system starts to run after power on;
[0019] Step (2), step (3) and step (4) are implemented according to the rest of the steps in Example 1, and finally the whole system is realized by changing the PLC into an electronic control integrated circuit and software numerical control, replacing the existing post-processing system of the kiln, Provide the required CAN signal to access the furnace ECU.
