Description

Technical Field

[0001] This utility model relates to the field of gas turbine ventilation devices, and in particular, to a gas turbine housing. Background Technology

[0002] The function of the ventilation system for the generator in a gas turbine enclosure is to remove the heat generated by the generator during operation, maintain a suitable temperature in the generator compartment inside the enclosure, and prevent the generator from operating normally due to excessively high temperatures.

[0003] Currently, the generator ventilation system in gas turbine generator sets used in industrial power plants is typically arranged at the top, with all components installed on the top of the enclosure. There is no precedent in China for integrating the generator ventilation system into the enclosure. This utility model integrates generator ventilation while including the generator, gearbox, and gas turbine within the enclosure, and allows for the disassembly, replacement, and maintenance of equipment within the enclosure without disassembling other systems. Summary of the Invention

[0004] The purpose of this utility model is to provide a gas turbine enclosure to solve the problems of insufficient top space in small gas turbine enclosures, making it difficult to install other equipment, the inability to integrate the generator and gas turbine into one enclosure, and the difficulty in disassembling and maintaining equipment inside the enclosure.

[0005] The above objective is achieved through the following technical solution: a gas turbine housing, including a main frame of the housing, with a gas turbine nacelle air inlet, a gas turbine air inlet, a gas turbine nacelle exhaust outlet, and a gas turbine exhaust outlet at the top of the housing, for connecting the gas turbine air intake system, the gas turbine exhaust system, the gas turbine nacelle air intake system, and the gas turbine nacelle exhaust system at the top of the housing.

[0006] The main frame of the enclosure contains the gas turbine compartment and the generator compartment, separated by a bulkhead. The bulkhead includes: a non-removable bulkhead welded to the main frame of the enclosure; and three removable bulkheads 01, 02, and 03, which are bolted to the main frame of the enclosure. The three bulkheads are also bolted together. The bulkhead reduces the impact of the gas turbine's heat on the generator compartment and reduces the mutual interference between the two compartments. The three removable bulkheads facilitate the installation of the gas turbine and gearbox connecting shafts.

[0007] The main frame of the enclosure has an inspection door on the non-exit side, which facilitates personnel to enter the enclosure to maintain the equipment; the exit side has a detachable door, detachable column, and detachable wall panel. After the whole unit is installed, if the gas turbine or generator fails, it can be taken out of the enclosure for maintenance through the passage formed by disassembling the detachable column, detachable wall panel, and detachable door; thus avoiding the need to disassemble the enclosure and the system above.

[0008] At the generator air inlet at the front of the main frame of the enclosure, a rainproof inertial separator adapter is welded to the outside of the enclosure to prevent water seepage at the bolted connections. An inertial separator is bolted to the rainproof inertial separator adapter at the front end to prevent rainwater from entering the generator air intake channel due to negative pressure at the air inlet, thus reducing filter pressure. The inside of the generator air inlet enclosure uses sheet metal and profiles welded together to form the generator air intake channel and filter support. A filter is installed on the generator air inlet side to filter dust particles in the air. The filter's filtration level can be changed according to generator usage requirements. The filter is secured with pressure plates and double nuts, ensuring installation stability while facilitating disassembly and replacement. A baffle valve is bolted to the inside of the generator air intake channel and filter support enclosure for fire suppression. Integrating the generator air intake system into the main frame of the enclosure saves space outside the enclosure, facilitating enclosure miniaturization.

[0009] At the generator exhaust vent on the side of the main frame of the enclosure, rainproof louvers are fixed on the outside of the enclosure to prevent rainwater from entering the generator exhaust duct. The generator exhaust vent is bolted to the inside of the enclosure to block fire sources. A generator exhaust reducer is bolted between the generator exhaust reducer and the generator exhaust vent. The main body of the generator exhaust reducer is made of canvas, with welded outer frames at both ends, secured by pressure plates and bolted together. The pressure plates facilitate the replacement of the middle canvas, and the canvas material of the main body makes it easy to install the generator.

[0010] Depending on actual usage needs, the removable wall panel can be converted into a removable door, a detachable door, or an inspection door. The main factor in whether it can be converted into a removable wall panel is whether there is a frequent need to enter the enclosure. Beneficial effects

[0011] The motor ventilation system of this utility model is integrated inside the housing frame, saving a lot of space outside the housing.

[0012] 2. The equipment inside the enclosure of this utility model is very convenient, whether maintenance personnel enter the enclosure for maintenance or the equipment is disassembled and taken outside the enclosure for maintenance.

[0013] 3. Because this utility model integrates the generator compartment and the gas turbine compartment into one box, it can form a skid, which facilitates transportation and reduces the amount of on-site installation work. Attached Figure Description

[0020] Figure 7 This is an external view of the gas turbine and generator of this utility model. Detailed Implementation

[0021] like Figure 1 As shown in Figure 2: A gas turbine housing, the top of which is provided with a gas turbine nacelle air inlet (41), a gas turbine air inlet (42), a gas turbine nacelle exhaust outlet (43), and a gas turbine exhaust outlet (44) for connecting the gas turbine air intake system, the gas turbine exhaust system, the gas turbine nacelle air intake system, and the gas turbine nacelle exhaust system at the top of the housing.

[0022] like Figure 4 As shown in .7: The main frame (01) of the enclosure contains the gas turbine compartment and the motor compartment, which are separated by a partition. The partition includes: a non-removable partition (31) welded to the main frame of the enclosure, a removable partition 01 (32), a removable partition 02 (33), and a removable partition 03 (34). These three detachable partitions are bolted to the main frame of the enclosure. The three partitions are bolted to each other and the connection is sealed with closed rubber seals. The partitions reduce the impact of the gas turbine's heat on the generator compartment and reduce the mutual influence between the two compartments. The three detachable partitions facilitate the installation of the gas turbine and gearbox connecting shaft. The main frame of the enclosure has an inspection door (25) on the non-exit side, which facilitates personnel to enter the enclosure to maintain the equipment. The exit side has a detachable door (22), a detachable column (24), and a detachable wall panel (21). If the gas turbine or generator fails after the whole machine is installed, the passage formed by disassembling the detachable column, detachable wall panel, and detachable door can be used for exit maintenance, avoiding the disassembly of the enclosure and the system above.

[0023] like Figure 2As shown in Figure 5: The practical type provides a generator ventilation system arrangement. Outside air enters the housing under the negative pressure attraction of the generator air inlet. If it is raining, most of the water droplets are blocked by the inertial separator (11). The inertial separator (11) and the rainproof inertial separator adapter (03) are connected by bolts. After passing through the filter 13, most of the dust and impurities in the air are filtered out and then enter the generator compartment of the housing. The filter (13) is fixed with a pressure plate and double nuts. The inner side of the filter (13) is made of plate and profile welded to form the generator air inlet channel and filter bracket (02). The filter (13) is installed on the side of the generator air inlet channel and filter bracket (02). The filter (13) is fixed with a pressure plate and double nuts. The inner side of the generator air inlet channel and filter bracket (02) is equipped with a baffle valve (14) and is connected by bolts. This realizes the air quality requirements of the generator air inlet and the usage requirements of the integrated generator air inlet channel in the housing.

[0024] like Figure 1 As shown in .6: Generator exhaust rainproof louvers (15) are fixed on the outside of the box. Generator exhaust damper valve (17) is bolted to the inside of the first generator exhaust port (16). There is a generator exhaust reducer (18) between the generator exhaust damper valve (17) and the second generator exhaust port (19). The generator exhaust reducer (18) is made of canvas and has a welded outer frame at both ends, which is connected by a pressure plate. The generator exhaust gas is discharged in the following order: second generator exhaust port (19), generator exhaust reducer (18), generator exhaust damper valve (17), generator exhaust rainproof louvers (15), and finally discharged outside the box.
