加热炉控制柜内温度过高,会导致加热炉频繁出现通讯模块故障、BMS燃烧器损坏、卡件及保险烧坏等问题,从而导致停炉。本文首先进行了半导体制冷器对箱体内部制冷的室内实验研究,结果表明,制冷器可以使箱体内温度比环境温度降低10℃～16℃,同时制冷器冷面板发生了结露现象。鉴于室内实验研究取得的良好效果,将半导体制冷器运用到集气站加热炉控制柜,采取半导体制冷器对箱体内部制冷;使用保温材料阻止外部热量进入到箱体内部,保存制冷器的制冷量;并用遮阳棚防止光线的直接照射。采用以上综合措施达到了加热炉控制柜的降温目的,满足了控制柜内部元件的温度要求,极大地降低了加热炉故障发生的概率。上述的方案保障了气井的正常生产。
Heating furnace control cabinet temperature is too high, can lead to frequent occurrence of furnace communication module failure, BMS burner damage, card and insurance burn and other issues, resulting in shutdown. In this paper, the first experiment on the interior of a refrigerator with a semiconductor refrigerator is carried out. The results show that the refrigerator can reduce the temperature in the cabinet by 10 ℃ ~ 16 ℃ than the ambient temperature, and the dew condensation on the cooler panel occurs. In view of the good results achieved in laboratory experiments, the semiconductor refrigerator is applied to the control cabinet of the heating furnace in the gas gathering station, and the interior of the cabinet is cooled by the semiconductor refrigerator. The heat insulation material is used to prevent external heat from entering the interior of the cabinet and the cooling of the refrigerator is saved Quantity; and with awning to prevent direct light exposure. Adopting the above comprehensive measures achieves the purpose of cooling the control cabinet of the heating furnace, meets the temperature requirements of the components inside the control cabinet and greatly reduces the probability of occurrence of the furnace failure. The above scheme guarantees the normal production of gas wells.
