Description

Technical Field

[0001] The utility model relates to the technical field of air intake filtration of a gas turbine, in particular to a plug-in type gas turbine air intake filtration control system. Background Art

[0002] The compressor of a gas turbine uses air as the working fluid. Improving the cleanliness of the inlet air can effectively alleviate problems such as scaling and wear on the compressor blade surface. Generally, it is necessary to assist with the intake system to filter droplets, dust, and suspended particles in the air to provide the gas turbine with clean air that meets the requirements. As the most important filtering device in the intake system, the filter will gradually be blocked by particles in the air after long-term operation, causing the pressure difference before and after the filter to gradually increase, affecting the intake pressure and filtration efficiency.

[0003] Common filter styles include straight plate and cylindrical types. Multiple filters are combined into a filter module. When a filter module is blocked, it needs to be cleaned or replaced directly. However, in the air intake system, many filter modules are distributed in the vertical direction. Under the action of gravity and flow field, particles in the air will be more easily deposited and attached to the middle and lower modules. As the air intake system continues to operate, the blockage of the lower modules will become more serious.

[0004] There are generally two ways to clean the filter module. One is to backflush the module online. However, the dirt blown off the upper module will further worsen the pollution of the lower module, and the cleaning effect is very limited. The other is to clean the module offline, dismantle the blocked module, clean it and then reinstall it. The operation is more cumbersome and requires a long period of downtime. Utility Model Content

[0008] The present application sets a filter assembly inside the outer frame, and the filter assembly includes multiple filter screens. The multiple filter screens are distributed in a circuitous manner inside the outer frame and are detachably installed through a cover assembly. The present application adopts such a setting not only to improve the filtering efficiency, but also each filter screen can be plugged in and out individually. When the filter screen is damaged or blocked, it only needs to be replaced or cleaned, and there is no need to remove the filter assembly as a whole. This solves the waste caused by the need to replace the traditional filter module as a whole when it is damaged. The filter screen of the present application is installed in such a circuitous and horizontal manner to prevent mutual contamination of dirt on the filter screen during online backblowing.

[0009] As a further solution of the utility model: a plurality of groups of the filter screens are connected end to end, and the filter screens located at both ends are respectively in contact with the inner ends of the outer frame.

[0010] As a further solution of the utility model: the upper and lower ends of several groups of the filter screens are installed in the installation grooves, wherein the installation grooves are also detachably installed in the upper and lower ends of the outer frame in a circuitous shape, and the filter screens can slide in the installation grooves.

[0011] As a further solution of the utility model: the plurality of groups of filter screens are in a "W"-shaped structure.

[0012] As a further solution of the utility model: the cover plate assembly includes a cover plate, a side baffle and a fastening block, and the two ends of the cover plate are installed with inwardly bent side baffles, wherein the cover plate is used to install the filter assembly from both sides of the outer frame.
