Embodiment 1
[0052] Embodiment one is the garbage biochemical aerobic treatment device of a single garbage pile, such as figure 1 As shown, the control method is as figure 2 , 3, 4, this is a typical biochemical aerobic treatment process garbage dump control system. Fan 3 is set beside the rubbish heap, the air outlet of the fan is connected to the ventilation duct 2, the air outlet of the ventilation duct is placed in the garbage heap, the probe 51 of the oxygen content measuring instrument 5 and the probe 41 of the temperature measuring instrument 4 are set in the garbage heap , the data input of the oxygen content measuring instrument and the temperature measuring instrument is a data input terminal of a controller, and the above-mentioned controller 6 further includes a memory, a timer, a central processing unit, an input device, and an output device; the controller measures the gas content The measurement signal of the instrument and the temperature measuring instrument is calculat...
Embodiment 2
[0055] Embodiment two is the rubbish biochemical aerobic treatment device of a plurality of rubbish heaps, as figure 2 As shown, the control method is as figure 2 , 3 As shown in , 4, when there are more than one garbage heap, there is a stop valve on the ventilation duct leading to each garbage heap, and a plurality of garbage heaps share a fan. For simplicity, only three garbage heaps A, B, c. A temperature measuring instrument probe 41 and an oxygen content measuring instrument probe 51 are arranged in the garbage dump 1 . The measured temperature signal and oxygen content data in each stack are sent to the controller 6, and the controller 6 determines the opening and closing of the shut-off valves 7A, 7B, and 7C. The total ventilation volume of the fan 3 is controlled by the pressure difference controller 8 using a pressure difference, that is, the pressure of the air ducts on both sides of the fan is measured and the pressure difference is kept constant. Likewise, t...
