Technical Field
[0001] This utility model relates to the field of environmental protection technology, specifically a gas turbine denitrification control device. Background Technology
[0002] Gas turbines, as important power equipment, generate large amounts of nitrogen oxides during operation, causing environmental pollution. Selective catalytic reduction (SCR) denitrification technology, with its highly efficient denitrification capability, has become a common method for nitrogen oxide control in gas turbines.
[0003] In practical applications, existing gas turbine SCR denitrification equipment suffers from uneven airflow distribution inside the equipment, resulting in insufficient contact between the airflow and the catalytic converter. This prevents the catalytic converter from fully utilizing its denitrification efficiency, thus reducing the overall denitrification efficiency. Furthermore, the existing equipment lacks a real-time monitoring mechanism for the treated airflow, making it difficult to adjust the denitrification process in a timely manner based on the actual treatment effect. This fails to meet increasingly stringent environmental protection requirements and hinders the continuous improvement of catalytic denitrification efficiency.
[0004] Based on the above reasons, this utility model proposes a gas turbine denitrification control device, which can achieve uniform regulation of the airflow generated by the gas turbine and complete real-time monitoring functions. Utility Model Content
[0005] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a gas turbine denitrification control device with the advantage of good denitrification effect.
[0006] The technical solution adopted by this utility model to achieve the above-mentioned objective is as follows: a gas turbine denitrification control device, including a housing, with mounting shells fixedly connected to both the left and right sides of the housing, a catalytic treatment device installed in the center of the inner cavity of the housing, a plurality of fixed rods evenly distributed and vertically intersectingly fixedly connected to the inner cavity of the housing near the right side, a plurality of first movable shells evenly distributed and movably connected to each fixed rod, a second movable shell fixedly installed on one side of the first movable shell, and a rotating assembly provided in the inner cavity of the first movable shell, a fixed plate fixedly connected to the inner cavity of the housing near the left side, a plurality of through holes opened on the fixed plate, and a monitoring module installed in each of the through holes.
[0007] In the above technical solution, the rotating component includes a motor, which is fixedly connected to the inner wall of the first movable shell. The output end of the motor is fixedly connected to a rotating shaft, and a first gear is fixedly connected to the rotating shaft. A second gear is fixedly connected to the side wall of the inner cavity of the first movable shell on the fixing rod, and the first gear and the second gear are meshed.
[0008] In the above technical solution, the monitoring module includes a flow detection unit, a pollutant detection unit, and a transmission unit; The flow detection unit is used to detect the gas flow rate through each through hole; The pollutant detection unit is used to detect the pollutant content in the gas after it has been treated by the catalytic treatment device. The transmission unit is used to transmit the data detected by the flow detection unit and the pollutant detection unit to the external main control device.
[0009] In the above technical solution, both the left and right sides of the first movable shell and the second movable shell are arc-shaped, and the right side diameter of the first movable shell and the second movable shell is smaller than the left side diameter.
[0010] In the above technical solution, a side plate is fixedly connected to the side of the first movable shell near the second movable shell, and a side groove is opened on the side of the second movable shell near the first movable shell. The side plate is inserted into the side groove, and bolts are threadedly connected to the upper and lower side walls of the second movable shell. One end of the bolt is inserted into the side plate.
[0011] In the above technical solution, the mounting shell includes a fixed shell, the length and width of the fixed shell on the side closer to the outer shell are greater than the length and width of the other side, and a round tube is fixedly connected to the side of the fixed shell away from the outer shell, and a flange plate is fixedly installed on the round tube.
[0012] In the above technical solution, a support base is fixedly connected to the bottom surface of the outer shell, and several hanging plates are evenly distributed and fixedly connected to the top surface of the outer shell.
[0013] The beneficial effects of this utility model are: 1. During the denitrification operation of the gas turbine, based on the detection data of each monitoring module, the motor at the designated position is started, and the motor drives the rotating shaft to rotate. The rotating shaft drives the first gear to mesh with the second gear, which can realize the rotation adjustment of the first and second movable shells. At this time, the airflow entering the inner cavity of the outer shell can be guided and controlled through the first and second movable shells, so that the airflow can be evenly and fully contacted with the catalytic treatment device, thereby improving the denitrification effect of the gas turbine. 2. After the catalytic treatment unit completes the denitrification treatment of the gas turbine flue gas, the gas passes through the through holes. At this time, the flow detection unit detects the gas flow rate in each through hole, and the pollutant detection unit detects the pollutant content inside the gas passing through the through holes. The detected data is transmitted to the external main control equipment through the transmission unit. The external main control equipment can adjust the rotation position of the first and second movable shells based on the flow rate to improve the treatment effect. It can also analyze the treatment status of the catalyst inside the catalytic treatment unit based on the pollutant content, and can replace or treat the catalyst in a timely manner to further improve the denitrification treatment effect of the gas turbine.

Through the installation shells 2, the device can be easily connected to the gas turbine exhaust equipment, and the hanging plates 22 can be used to easily lift and move the device. The support base 21 can be used to stably place the device. Several fixed rods 4 are evenly distributed and vertically intersecting and fixedly connected to the inner cavity of the outer shell 1 near the right side. Several first movable shells 5 are evenly distributed and movably connected to each fixed rod 4. A second movable shell 6 is fixedly installed on one side of the first movable shell 5. A rotating assembly 7 is provided in the inner cavity of the first movable shell 5. The rotating assembly 7 includes a motor 11.

The first gear 13 and the second gear 14 are meshed. In the above technical solution, during the gas turbine denitrification operation, based on the detection data of each monitoring module 10, the motor 11 at the designated position is started, and the motor 11 is controlled to drive the rotating shaft 12 to rotate. The rotating shaft 12 drives the first gear 13 to mesh with the second gear 14 to move, which can realize the rotation adjustment of the first movable shell 5 and the second movable shell 6. At this time, the airflow entering the inner cavity of the outer shell 1 can be guided and controlled through the first movable shell 5 and the second movable shell 6, so that the airflow can be evenly and fully contacted with the catalytic treatment device 3, thereby improving the denitrification effect of the gas turbine. Furthermore, both the left and right sides of the first movable shell 5 and the second movable shell 6 are arc-shaped, and the right diameter of the first movable shell 5 and the second movable shell 6 is smaller than the left diameter, which facilitates the passage of airflow and thus makes the denitrification treatment of the gas turbine more effective.

A monitoring module 10 is installed in each of the through holes 9. The monitoring module 10 includes a flow detection unit, a pollutant detection unit and a transmission unit. The flow detection unit is used to detect the gas flow rate through each through hole 9; The pollutant detection unit is used to detect the pollutant content in the gas after it has been treated by the catalytic treatment device 3.
