The invention discloses an automatic nitrogen charging device which comprises equipment to be charged with nitrogen, a nitrogen charging module, a nitrogen drying module communicated with the nitrogencharging module through a pipeline, and a control system electrically connected with the nitrogen charging module and the nitrogen drying module, wherein the nitrogen charging module comprises a nitrogen making machine, and the nitrogen making machine is connected with the equipment to be charged with nitrogen through a nitrogen pipeline; and the nitrogen drying module comprises a circulating fan, a heater and a drying box which are sequentially communicated with the equipment to be filled with nitrogen through pipelines. The invention further discloses a using method of the automatic nitrogen charging device. The automatic nitrogen charging device can be used for nitrogen charging dehumidification and maintenance of thermal equipment. The automatic nitrogen charging device is simple in structure and easy to realize, solves the problem of poor dehumidification effect in nitrogen charging maintenance of existing thermal equipment, is high in automation degree, can work under unattendedoperation for a long time after equipment debugging is completed, can realize quantitative nitrogen charging, greatly reduces the workload of nitrogen charging maintenance and the like.
Description
technical field [0001] The invention relates to the technical field of equipment corrosion control, in particular to an automatic nitrogen charging device and a use method. Background technique [0002] Steam turbines, high-pressure heaters, low-pressure heaters, deaerators, heating network heaters, internal cooling water systems, and constant cooling water systems in thermal power plants are expensive. During equipment shutdown, in order to avoid atmospheric corrosion of equipment, nitrogen filling maintenance is a must. One of the commonly used maintenance methods. [0003] In the prior art, thermal equipment generally dehumidifies the equipment before performing nitrogen filling maintenance, such as performing compressed air blowing to remove residual moisture in the equipment, but this dehumidification method has limited effects, and some equipment dead ends such There is residual water that cannot be removed during the compressed air blowing phase. Since the oxygen in...
