Rapid replacing system for air pre-filtering device

Abstract

The invention provides a rapid replacing system for an air pre-filtering device, and relates to the technical field of air inlet systems of gas turbines and industrial compressors. The rapid replacingsystem comprises a pre-filtering device, wherein a pre-filtering module is arranged on the surface of the pre-filtering device, a supporting component is embedded in the bottom of the side surface ofthe pre-filtering device, and a lifting mechanism is arranged at the bottom surface of the pre-filtering device. The pre-filtering element can be quickly replaced on line without stopping; the replacement is simple, the labor intensity is low, the operation environment is excellent, and no additional tool or fixture is needed; and the pre-filtering element shares the filtering burden of a downstream filter, prolongs the service life of the downstream filter with high purchase cost, reduces the frequency of unplanned stoppage, and improves the reliability and economical efficiency of machine operation.

Description

technical field [0001] The invention relates to the technical field of air intake systems of gas turbines and industrial compressors, in particular to a quick replacement system for air pre-filtering devices. Background technique [0002] The air intake system provides clean air for turbomachinery such as gas turbines and industrial compressors through filtration and dehumidification to ensure its efficient, safe and reliable operation. The air intake system is designed according to the specific ambient air quality, but the actual operation The ambient air quality is ever-changing under the conditions, and it is normal to deviate from the design conditions, which leads to the filter life of the air intake system being shorter than the expected life of the design, requiring frequent replacement of filter elements, increasing the frequency and cost of unplanned shutdowns to replace filter screens, and replacing filter elements requires Operating in the intake room, there is a ...

[0002] The intake system provides clean air for turbomachinery such as gas turbines and industrial compressors through filtration and dehumidification to ensure its efficient, safe and reliable operation. The intake system is designed according to the specific ambient air quality, but the actual operation The ambient air quality is ever-changing under the conditions, and it is normal to deviate from the design conditions, which leads to the filter life of the intake system being shorter than the expected life of the design, requiring frequent replacement of filter elements, increasing the frequency and cost of unplanned shutdowns to replace filter screens, and replacing filter elements requires Operating in the intake room, there is a lot of flying dust and the working environment is harsh. At the same time, due to the large volume of the intake system of large gas turbines and industrial compressors, the replacement workload is heavy. , the replacement cycle of the filter screen is shorter during the period of high pollen occurrence, which has a greater impact on the safe, reliable and economical operation of the turbine machinery. Therefore, it is necessary to develop a pre-filter device that can be replaced online outdoors
