Description

Technical Field

[0001] The utility model relates to the technical field of gas filtering devices, in particular to a gas turbine filter. Background Technique

[0002] The gas filtering device is an indispensable device in the pipeline series for conveying media, and is usually installed at the air inlet end of the gas turbine. The main function of the gas filtering device at the air inlet end of the gas turbine is to filter out dust particles, harmful gases, solid substances, etc. in the gas or air, so that the gas entering the gas turbine is clean, and prevent substances such as dust particles and water vapor gels in the air from entering the air duct, resulting in a reduction in the air intake of the gas turbine, thereby reducing the output power and thermal efficiency of the gas turbine generator set, preventing the compressor blades from being soiled and generating vibrations, and increasing the power consumption during the operation of the unit. For example, the gas turbine air filtering device disclosed in the Chinese patent with the authorized announcement number CN205315126U includes a closed shell. An air inlet duct is arranged in the middle of the air inlet end of the closed shell, an air outlet channel is arranged at the air outlet end of the closed shell, a filter element is arranged in the closed shell, the filter element is provided with a sandwich structure, one end of the filter element is a closed end, and the other end is an open end. The open end of the filter element is connected to the air inlet duct, and calcium oxide is filled in the sandwich structure. By setting a filter element with a sandwich structure, calcium oxide for absorbing moisture and acidic gases in the gas is arranged in the sandwich structure, a pressure difference is formed between the inner and outer sides of the filter element, so that the gas permeates from the outside of the filter element to the inside of the filter element, realizing the filtration of the gas, and the filtered gas is discharged from the open end of the filter element. The structure of the utility model is simple; and the filtration method adopted by the utility model is from the inside to the outside of the filter element, and the internal pressure of the filter element is much greater than the external pressure, which can effectively improve the filtration efficiency.

[0003] However, in practical applications, the above filtering device still has the following deficiencies: during long-term use, a large amount of dust particles will adhere to the filter mesh, and a large amount of moisture and acidic gases will also be absorbed in the calcium oxide, seriously affecting the filtering speed and filtering effect of the filtering device, and it is necessary to frequently stop the machine for a long time for cleaning and replacement, affecting the working efficiency of the gas turbine. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a gas turbine filter for the above deficiencies, which can ensure the gas filtering speed and filtering effect without stopping the machine for a long time to replace the filter mesh and calcium oxide, and ensure the working efficiency of the gas turbine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A gas turbine filter includes a cylindrical hollow housing, a rotating plate rotatably connected inside the housing, a partition plate fixed on the rotating plate, a rotary electric cylinder used to drive the rotation of the rotating plate, an intake pipe and an outlet pipe symmetrically arranged up and down. The partition plate divides the interior of the housing into a replacement chamber and a filtration chamber from left to right in sequence. Filter cores are detachably connected in the replacement chamber and the filtration chamber respectively. Intake ports are symmetrically arranged left and right on the rotating plate, and the intake ports are arranged facing the filter cores. The outlet end of the intake pipe is arranged facing the intake port in the filtration chamber, and the intake end of the outlet pipe is arranged facing the top end of the filter core in the filtration chamber. An opening is arranged on the housing facing the replacement chamber.

[0007] Further, a connecting sleeve is fixed on the rotating plate facing the intake port, and an external thread one is arranged on the connecting sleeve; the filter core includes a filter tube, a first filter net and a second filter net symmetrically arranged up and down inside the filter tube, calcium oxide arranged between the first filter net and the second filter net, and an internal thread one is arranged at the bottom of the filter tube facing the external thread one.

[0008] Further, the filter tube includes a tube body, a first mesh ring detachably connected to the top end of the tube body, and a second mesh ring detachably connected to the bottom end of the tube body. The first mesh ring and the second mesh ring are respectively used to install the first filter net and the second filter net, and a corresponding sleeve is arranged at the bottom end of the second mesh ring. The internal thread one is arranged on the corresponding sleeve.

[0009] Further, screwing handles are symmetrically arranged left and right on the outer side of the filter tube, and the screwing handles are arranged perpendicular to the screwing direction of the filter tube.

[0010] Further, valve bodies are respectively arranged on the intake pipe and the outlet pipe.

[0011] Further, a sealing gasket is arranged on the partition plate, and the sealing gasket is arranged on the contact surface between the partition plate and the housing.

[0012] The beneficial effects of the present utility model are:

[0013] In practical applications, when in use, gas enters the filtration chamber through the intake pipe and the intake port of the filtration chamber, and after being filtered by the filter core, it is discharged from the outlet pipe; when it is necessary to replace the filter net and calcium oxide, the rotary electric cylinder drives the rotating plate to rotate by °, and the positions of the two filter cores are swapped. During the continuous operation of the gas turbine, the used filter core in the replacement chamber can be replaced through the opening, ensuring the working efficiency of the gas turbine; the present utility model can ensure the filtration speed and filtration effect of the gas without long-term shutdown for replacing the filter net and calcium oxide, and ensures the working efficiency of the gas turbine.
