Abstract

The invention discloses an operation control method of a hot film methane hot wind utilization control system, wherein methane generated during the beer production process is recycled and utilized. Meanwhile, hot wind generated during the methane combustion process is adopted for the plastic heat shrinkable film packaging of beers, instead of a high-energy electrical-heating hot wind system of a hot film packing machine. Thus, the electric energy of about 4 KWH per ton of beer is saved and the production cost is reduced. In addition, a methane combustion regulation valve is operated with the cooperation of the online arrangement of a methane density sensor, a methane pressure sensor and a hot wind temperature detection sensor in a pipeline, while the temperature of hot wind is adopted as the master feedback of a piping and instruments diagram (PID), with the methane density and the methane pressure as the feedforward of the system. Thus, the opening degree of the methane combustion regulation valve is timely corrected and the temperature of hot wind is controlled relatively stable within the range of 260 + / -10 DEG C. The hot film packaging quality is then ensured.

Description

technical field [0001] The invention relates to the field of beer production, in particular to a hot film biogas hot air utilization control system and an operation control method thereof. Background technique [0002] Traditional beer hot film packaging mostly adopts the mode of electric heating and hot air, and the power consumption is relatively high. The high-nutrient substances discharged from the beer production process will produce a large amount of methane after anaerobic treatment of sewage. If they are not treated and directly discharged into the atmosphere, the greenhouse effect caused by carbon dioxide will be more than 5 times stronger. As we all know, biogas is a mixed gas whose main component is methane (CH 4 ) and carbon dioxide (CO 2 ), and a small amount of gases such as hydrogen, carbon monoxide, hydrogen sulfide, oxygen and nitrogen. Because the methane content in biogas is as high as 60% to 70%, and the flame is blue when methane is mixed with air and...
