Description

Technical Field

[0001] This invention relates to the field of gas-fired power generation equipment, and in particular to a gas-fired power generation equipment for IGCC (In-Gas Concentration Gas Cylinder) generator. Background Technology

[0002] The existing IGCC power generation unit in large power plants combines gas turbine power generation and steam turbine power generation. It generates steam by recovering the high-temperature waste heat emitted by the gas turbine, which then drives the steam turbine to generate electricity, thereby improving the overall power generation efficiency.

[0003] A gas turbine comprises a compressor, a burner, and a gas turbine. The compressor's function is to draw in air and compress it, increasing its pressure. This process provides the necessary conditions for subsequent combustion, allowing the fuel to burn more completely and release more energy. However, when the compressor's inlet draws in air, impurities in the air can easily clog the filters, reducing the amount of air entering the compressor and hindering complete fuel combustion. Currently, replacing the filters often requires shutting down the turbine to prevent impurities from entering, impacting equipment utilization. Summary of the Invention

[0004] To address the problem mentioned in the background art that the machine needs to be shut down every time the filter element is replaced, the present invention provides the following technical solution:

[0005] A gas-fired power generation device for IGCC includes a filter box inlet for supplying air to the interior of the filter box compressor end;

[0006] The air inlet end of the filter box includes a filter box, and the inner cavity of the filter box is equipped with a first filter element and a second filter element for filtering air, and the first filter element is only used when the second filter element is replaced.

[0007] The upper end of the first filter element is equipped with a top limiting member for limiting the second filter element, and the first filter element is installed at the lower end of the top limiting member, while the second filter element is installed at the upper end of the top limiting member.

[0008] The filter box is equipped with a top cover for sealing the filter box, and a conversion component for opening and closing the bottom of the top limiting component is installed in the middle of the top limiting component.

[0009] Furthermore, an air inlet pipe for conveying filtered air is installed at the upper end of the compressor end of the filter box, and the air inlet pipe is installed at the lower end of the filter box. One end of the compressor end of the filter box is connected to a burner chamber, and one end of the burner chamber is connected to a gas turbine end.

[0010] Furthermore, a fixing ring block is installed on the outer wall of the middle part of the first filter element, and multiple sliders are installed on the outer wall of the fixing ring block.

[0011] Furthermore, a limiting ring block is installed in the inner cavity of the filter box. The inner wall of the limiting ring block is machined with multiple limiting vertical grooves for the slider to move up and down. A support rod for supporting the conversion component is installed at the bottom of the limiting ring block.

[0012] Furthermore, a bottom limiting member for supporting the first filter element is installed at the lower end of the limiting ring block, and a limiting groove for limiting the first filter element is machined at the upper end of the bottom limiting member. An air inlet for supplying air into the inner cavity of the filter box is installed on the left side of the filter box.

[0013] Furthermore, the second filter element includes an outer frame for limiting the position of the second filter element.

[0014] Furthermore, the top limiting component includes a lifting ring, the lower end of which is machined with a limiting groove 2 for limiting the first filter element, the inner wall of which is machined with a plurality of limiting holes 1, the cavity of which is fitted with an internal hexagon bolt for locking the first filter element, the upper end of which is machined with a stepped groove for limiting the outer frame, the side wall of which is machined with a plurality of limiting grooves 3, and the lower end of which is fitted with a connecting pipe for limiting the conversion component.

[0015] Furthermore, the lower end of the connecting pipe is machined with a plurality of limiting grooves four, the upper end of the cavity of the limiting groove four is machined with limiting holes two, and a limiting rod is installed in the middle of the cavity of the limiting groove four.

[0016] Furthermore, the conversion component includes an electric push rod, the upper end of which is equipped with a telescopic rod for controlling the upward movement of the first filter element, the second filter element, and the top limiting element. The conversion component includes a baffle for opening and closing the lower end of the top limiting element. A rotating rod for controlling the stretching of the baffle is installed on one side of the baffle, and the rotating rod is installed in the cavity of the limiting groove four. One end of the rotating rod is machined with a limiting hole three for cooperating with the limiting rod to limit the rotating rod. A pressure plate for limiting the baffle is installed on the other side of the rotating rod. A torsion spring for controlling the rotation of the rotating rod is installed on one end of the rotating rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] When the second filter element is disassembled, cleaned, or replaced, the electric push rod controls the telescopic rod to move upward. Simultaneously, the telescopic rod moves the first filter element, the second filter element, and the top limiting component upward, causing the upper end of the electric push rod to move away from the connecting pipe. The electric push rod releases its push on the rotating rod, and under the action of the torsion spring, pushes the rotating rod, causing the outer side of the rotating rod to flip upward. Simultaneously, the baffle cloth flips, and the outer side of the baffle cloth fits against the bottom of the lifting ring, preventing unfiltered air from entering the intake connecting pipe through the top limiting component. As the telescopic rod moves the first filter element upward, air simultaneously passes through the first filter element for filtration and is then transported to the compressor end of the filter box through the intake connecting pipe. When the second filter element becomes clogged, the top limiting component and the conversion component allow for replacement of the second filter element without shutting down the gas turbine. During replacement, the first filter element filters the air; after replacement, the second filter element continues to filter the air. Attached Figure Description

[0039] The preferred embodiments of the present invention are described in detail below, and a clear and complete description is provided in conjunction with the accompanying drawings.

[0040] Please see Figure 1-9 The present invention provides a gas-fired power generation device for IGCC, including a filter box inlet end 01 for supplying air to the interior of the filter box compressor end 10.

[0041] An air inlet pipe 11 for conveying filtered air is fixedly installed at the upper end of the compressor end 10 of the filter box, and the air inlet pipe 11 is fixedly installed at the lower end of the filter box 100. A burner chamber 20 is connected to the right end of the compressor end 10 of the filter box, and a gas turbine end 30 is connected to the right end of the burner chamber 20. The filtered air enters the interior of the compressor end 10 of the filter box from the air inlet pipe 11, expands in the direction of the gas turbine end 30 through the burner chamber 20, and drives the turbine to generate electricity.

[0042] The air inlet end 01 of the filter box includes a filter box 100. The inner cavity of the filter box 100 is equipped with a first filter element 200 and a second filter element 300 for filtering air. The first filter element 200 is only used when the second filter element 300 is replaced. When the second filter element 300 needs to be disassembled for cleaning or replacement after long-term use, the second filter element 300 moves to the upper end of the filter box 100, and the first filter element 200 moves upward simultaneously, allowing air to pass through the first filter element 200 for filtration, facilitating the replacement of the second filter element 300.

[0043] A fixing ring block 210 is fixedly installed on the outer wall of the middle part of the first filter element 200, and multiple sliders 211 are fixedly installed on the outer wall of the fixing ring block 210.

[0044] A limiting ring block 110 is fixedly installed in the middle of the inner cavity of the filter box 100. The inner wall of the limiting ring block 110 is machined with multiple limiting vertical grooves 112 for the slider 211 to move up and down. A support rod 111 for supporting the conversion component 600 is fixedly installed at the bottom of the limiting ring block 110.

[0045] The lower end of the limiting ring block 110 is movably mounted with a bottom limiting member 120 for supporting the first filter element 200. Multiple sliders for sliding within the cavity of the limiting vertical groove 112 are mounted on the outer wall of the bottom limiting member 120. The upper end of the bottom limiting member 120 is machined with a limiting groove 121 for limiting the first filter element 200. During installation of the first filter element 200, the lower end of the first filter element 200 is inserted into the cavity of the limiting groove 121, and the first filter element 200 is fixed above the bottom limiting member 120 by the internal hexagonal bolts on the inner wall of the bottom limiting member 120.

[0046] An air inlet 130 for supplying air into the inner cavity of the filter box 100 is fixedly installed on the upper left side.

[0047] The second filter element 300 includes an outer frame 310 for limiting the second filter element 300, and a plurality of mounting blocks are fixedly installed on the outer wall of the outer frame 310.

[0048] The upper end of the first filter element 200 is equipped with a top limiting member 400 for limiting the second filter element 300, and the first filter element 200 is installed at the lower end of the top limiting member 400, while the second filter element 300 is fixedly installed at the upper end of the top limiting member 400 by bolts.

[0049] The top limiting member 400 includes a lifting ring 410. The lower end of the lifting ring 410 is machined with a limiting groove 411 for limiting the first filter element 200. The inner wall of the lifting ring 410 is machined with a plurality of limiting holes 412. The cavity of the limiting hole 412 is fitted with an internal hex bolt 420 for locking the first filter element 200. The upper end of the first filter element 200 is inserted into the cavity of the limiting groove 411 and locked by the internal hex bolt 420, so that the top limiting member 400 is fixed to the upper end of the first filter element 200. When the first filter element 200 moves up and down, the top limiting member 400 moves up and down synchronously.

[0050] The upper end of the top limiting member 400 is machined with a stepped groove 413 for limiting the outer frame 310. The side wall of the stepped groove 413 is machined with multiple limiting grooves 414. When the second filter element 300 is installed, the outer frame 310 is placed into the groove of the stepped groove 413, and the mounting block on the outer wall of the outer frame 310 is in the groove of the limiting groove 414. The second filter element 300 is fixed to the upper end of the lifting ring 410 by bolts. When the top limiting member 400 moves up and down, it drives the second filter element 300 to move up and down synchronously.

[0051] A connecting pipe 430 for limiting the conversion component 600 is fixedly installed at the lower middle part of the top limiting component 400. Multiple limiting grooves 431 are machined at the lower end of the connecting pipe 430. Limiting holes 432 are machined at the upper end of the groove cavity of the limiting groove 431. A limiting rod 433 is installed in the middle of the groove cavity of the limiting groove 431.

[0052] The filter box 100 is equipped with a top cover 500 for sealing the filter box 100. When the second filter element 300 is replaced, the first filter element 200, the second filter element 300 and the top limiting member 400 move upward. When the horizontal height of the top limiting member 400 is higher than the air inlet 130, the top cover 500 is opened, and the second filter element 300 can be disassembled, cleaned or replaced.

[0053] A conversion element 600 for opening and closing the bottom of the top limiting member 400 is installed in the middle of the top limiting member 400. The conversion element 600 is used to switch the air intake state and the closed state of the top limiting member 400. The conversion element 600 includes an electric push rod 610. The bottom end of the electric push rod 610 is fixedly installed in the middle of the support rod 111. The upper end of the electric push rod 610 is equipped with a telescopic rod 611 for controlling the upward movement of the first filter element 200, the second filter element 300 and the top limiting member 400. The upper end of the telescopic rod 611 is fixedly installed in the middle of the bottom end of the top limiting member 400.

[0054] The conversion component 600 includes a baffle 620 for opening and closing the lower end of the top limiting component 400. A rotating rod 630 for controlling the stretching of the baffle 620 is installed on one side of the baffle 620. The rotating rod 630 is movably installed in the cavity of the limiting groove 431. One end of the rotating rod 630 is machined with a limiting hole 631 for cooperating with the limiting rod 433 to limit the rotating rod 630, so that the rotating rod 630 can rotate in the cavity of the limiting groove 431.

[0055] After the second filter element 300 is replaced, the electric push rod 610 controls the telescopic rod 611 to move downward. The upper end of the telescopic rod 611 approaches the upper end of the electric push rod 610, and the top of the electric push rod 610 abuts against the end of the rotating rod 630 near the limit rod 433, causing the rotating rod 630 to rotate. This causes the other end of the rotating rod 630 to approach the side wall of the electric push rod 610, thereby causing the outer side of the baffle 620 to flip downward, so that the air filtered by the second filter element 300 can flow to the air inlet connecting pipe 11.

[0056] On the other side of the rotating rod 630, a pressure plate 640 is installed to limit the position of the baffle 620. Multiple bolts 641 for fixing the baffle 620 to the rotating rod 630 are installed in the middle of the pressure plate 640. A torsion spring 650 for controlling the rotation of the rotating rod 630 is installed at one end of the rotating rod 630. One end of the torsion spring 650 is installed in the cavity of the limiting hole 432, and the other end of the torsion spring 650 is fixed to the rotating rod 630. The torsion spring 650 is sleeved in the middle of the rod body of the limiting rod 433.

[0057] When the second filter element 300 is disassembled, cleaned, or replaced, the electric push rod 610 controls the telescopic rod 611 to move upward. The telescopic rod 611 simultaneously moves the first filter element 200, the second filter element 300, and the top limiting member 400 upward, causing the upper end of the electric push rod 610 to move away from the connecting pipe 430. The electric push rod 610 then releases its push on the rotating rod 630. Under the action of the torsion spring 650, the rotating rod 630 is pushed, causing its outer side to flip upward. Simultaneously, this causes the baffle cloth 620 to flip, and the outer side of the baffle cloth 620 fits against the bottom of the lifting ring 410, preventing unfiltered material from being filtered. Air enters the intake connection pipe 11 through the top limiting member 400, and when the telescopic rod 611 drives the first filter element 200 to move upward, the air is simultaneously filtered through the first filter element 200 and transported to the interior of the compressor end 10 of the filter box through the intake connection pipe 11. When the second filter element 300 becomes blocked, the top limiting member 400 and the conversion member 600 enable the second filter element 300 to be replaced without shutting down the gas turbine. During replacement, the first filter element 200 filters the air, and after replacement, the second filter element 300 continues to filter the air.

[0058] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this invention. Furthermore, any non-creative modifications made to this invention by those skilled in the art without inventive effort are still within the scope of protection of this invention.
