Embodiment Construction
[0015] Such as figure 2 The shown gas-liquid two-phase guiding well automatic control system includes at least one guiding well 5, and a gas-liquid guiding device 2 is correspondingly arranged in each guiding well 5, and also includes a device for guiding each gas-liquid guiding well. The exhaust device 2 is a control device 1 for controlling exhaust and liquid discharge, a gas treatment device 3 for processing the gas discharged by each gas-liquid guiding device 2 , and a liquid collection device 4 .
[0016] image 3 and Figure 4 Shown is a block diagram of an embodiment of the gas-liquid two-phase drainage well automatic control system of the present invention applied to a landfill. In this embodiment, the control of a single drainage well to guide and discharge biogas and sewage is taken as an example to carry out the system Detailed description.
[0017] In this embodiment, the control device 1 includes: an air filter 11 , an air compressor 12 , a compressed air buff...

The embodiment of the invention relates to a gas-liquid discharge well automatic control system and a gas-liquid discharge well discharge method. The control system comprises at least one discharge well, gas-liquid discharge devices arranged in the discharge well, a control device which is used for controlling the gas and liquid discharge of each gas-liquid discharge device and a gas treatment device which is used for treating gas output by each gas-liquid discharge device. By the discharge system, gas and liquid can be automatically discharged, and more methane can be generated by the displacement of the methane and sewage from a garbage body to the discharge well along with the ascending and descending of the level of liquid in the well and the change of gas pressure, so that the methane can be effectively recycled, and pollution to the environment due to the disordered discharge of the methane and the sewage can be prevented simultaneously. The gas-liquid discharge well automatic control system can also be popularized and applied in processes such as drying, ventilation, gas replacement, water discharging and the like in the large and medium material aggregation process of industries such as foods, deep processing, chemical engineering, medicine and the like.
Description
technical field [0001] The invention relates to a gas-liquid guiding and discharging technology for a material stack, in particular to an automatic control system and a guiding method for a gas-liquid two-phase guiding well. Background technique [0002] The disposal of urban domestic waste in my country mainly adopts landfill treatment. The anaerobic decomposition of the waste in the landfill will produce a large amount of landfill gas, and at the same time, the waste body will seep high-concentration toxic and harmful sewage. Landfill gas is a recyclable energy source and a polluting gas at the same time. Therefore, in order to comprehensively utilize landfill gas and turn waste into treasure, it is the current domestic gas collection system to establish a gas-liquid drainage system in landfill sites. and the main way of liquid handling. Current landfill drainage systems such as Figure 1 As shown, its working principle is: after the landfill gas is filtered by the crushe...
