Description

Technical Field

[0001] This application relates to the technical field of waste-to-energy incineration plants, and in particular to a diesel fuel circulation system insulation system for waste-to-energy incineration plants. Background Technology

[0002] Currently, we are in a cold and low-temperature environment. When incoming waste is mixed with ice, it enters the waste storage of the waste incineration power plant. The low temperature inhibits the fermentation of the incoming waste in the waste storage. Therefore, under extreme cold weather, the frequency of shutdowns of waste incineration power plants increases, and it is necessary to restart the furnace by using burners and diesel ignition.

[0003] In related technologies, the oil passage from the diesel storage to the furnace is affected by extreme low temperatures, which can reduce the fluidity or even solidify the diesel, making it impossible to ignite and even causing serious accidents during troubleshooting. Utility Model Content

[0004] The purpose of this application is to provide a diesel circulation oil circuit insulation system for waste incineration power plants, in order to solve the problem that the oil circuit from the diesel storage to the furnace is affected by extreme low temperature, which reduces the fluidity or even solidifies the diesel, making it impossible to ignite, and may even cause serious accidents during troubleshooting.

[0005] The technical solution provided in this application for a diesel circulation oil circuit insulation system in a waste incineration power plant area is as follows: A diesel circulation oil circuit insulation system for a waste incineration power plant includes a diesel storage tank and a furnace. A outgoing oil circuit is provided between the diesel storage tank and the furnace, and a return oil circuit is also provided between the diesel storage tank and the outgoing oil circuit. A steam turbine generator is provided on one side between the diesel storage tank and the furnace. One end of the condensate pipe of the steam turbine generator is connected to a condensate branch pipe. The body of the condensate branch pipe is in close contact with the outer side of the outgoing oil circuit and the outer side of the return oil circuit, respectively.

[0006] Furthermore, a heat-insulating assembly is provided around the condensate branch pipe and the outgoing oil circuit, which are closely attached to each other. The heat-insulating assembly includes a first heat-insulating sleeve and a second heat-insulating sleeve respectively symmetrically sleeved around the condensate branch pipe and the outgoing oil circuit. Multiple first locking elements are provided between the first heat-insulating sleeve and the second heat-insulating sleeve.

[0007] Furthermore, the first insulation sleeve and the second insulation sleeve are both wrapped with a first insulation cotton.

[0008] Furthermore, a loop insulation component is provided around the condensate branch pipe and the return pipeline oil circuit, which are closely attached to each other. The loop insulation component includes a third insulation sleeve and a fourth insulation sleeve symmetrically sleeved around the condensate branch pipe and the return pipeline oil circuit, respectively. Multiple second locking elements are provided between the third insulation sleeve and the fourth insulation sleeve.

[0009] Furthermore, the outer periphery of both the third and fourth insulation sleeves is wrapped with a second insulation cotton.

[0010] Furthermore, a diesel pump is also installed on the oil supply line.

[0011] Furthermore, valves are respectively installed on the condensate branch pipe and the return pipeline oil line.

[0012] Furthermore, it also includes a boiler, with the end of the condensate branch pipe away from the steam turbine generator connected to the boiler.

[0013] Compared with the prior art, the beneficial effects of this application are as follows: By configuring the condensate branch pipes on the turbine generator to be tightly connected to the outer sides of both the outgoing and return oil lines, the condensate collected after the turbine generator has performed its work is channeled along these branch pipes. The residual heat of the condensate is used to maintain the temperature of both the outgoing and return oil lines, ensuring that the diesel fuel entering the furnace from the diesel storage is not affected by extreme low temperatures, preventing reduced fluidity or even solidification. Furthermore, even in extreme low-temperature climates, there is no need to use antifreeze diesel fuel, thus reducing diesel ignition costs in such conditions. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a diesel circulation oil circuit insulation system for a waste incineration power plant, referring to... Figure 1 In this embodiment, the diesel circulating oil circuit insulation system includes a diesel storage tank 1, a furnace 2, a discharge oil circuit 3, a return pipeline oil circuit 4, a steam turbine generator 5, and a condensate branch pipe 6. One end of the discharge oil circuit 3 is connected to the oil outlet of the diesel storage tank 1, and the other end is connected to the oil inlet of the furnace 2. A diesel pump 15 is installed on the end of the discharge oil circuit 3 closest to the diesel storage tank 1. When the diesel pump 15 is started, diesel fuel is drawn from the diesel storage tank 1 and then discharged into the interior of the furnace 2 along the discharge oil circuit 3.

[0020] Meanwhile, one end of the return pipeline oil line 4 is connected to the oil inlet of the diesel storage tank 1, and the other end is connected to the end of the outgoing oil line 3 near the furnace 2. By setting up the return pipeline oil line 4, the diesel pump 15 can be effectively protected to prevent damage caused by pressure buildup. Furthermore, a valve 16 is installed on the end of the return pipeline oil line 4 near the outgoing oil line 3. The function of the valve 16 is to control the opening and closing of the return pipeline oil line 4 to facilitate the flow of diesel fuel.

[0021] Additionally, refer to Figure 1 In this embodiment, the steam turbine generator 5 is located on one side between the diesel storage tank 1 and the furnace 2, and the outlet end of the steam turbine generator 5 is connected to a condensate pipe; one end of the condensate branch pipe 6 is fixedly connected to the end of the condensate pipe away from the steam turbine generator 5, and the diesel circulation oil circuit insulation system also includes a boiler 17, and the end of the condensate branch pipe 6 away from the steam turbine generator 5 is connected to the inlet end of the boiler 17; at the same time, the pipe body of the condensate branch pipe 6 is closely attached to the outer side of the outgoing oil circuit 3 and the outer side of the return pipeline oil circuit 4 respectively.

[0022] Preferably, a valve 16 is also installed on the end of the condensate branch pipe 6 near the turbine generator 5. The function of the valve 16 is to control the opening and closing of the condensate branch pipe 6 so as to facilitate the flow of condensate.

[0023] After the steam turbine generator 5 finishes its work, the condensate obtained is then fed into the condensate branch pipe 6 through the condensate pipe. The condensate flows inside the condensate branch pipe 6. Since the pipe body of the condensate branch pipe 6 is in close contact with the outer side of the outgoing oil line 3 and the outer side of the return oil line 4, the residual heat of the condensate can be used to maintain the temperature of the outgoing oil line 3 and the return oil line 4. This ensures that the diesel fuel entering the furnace 2 from the diesel fuel storage 1 is not affected by extreme low temperatures, which could lead to reduced fluidity or even solidification.

[0024] Meanwhile, even in extreme low-temperature climates, there is no need to use diesel fuel with antifreeze grade, thereby reducing the cost of diesel ignition in extreme low-temperature climates; in addition, after the condensate in the condensate branch pipe 6 has completed heat exchange with the outgoing oil line 3 and the return pipeline oil line 4, it can return to the boiler 17, thereby enabling the collection and treatment of the condensate after heat exchange.

[0025] In addition, refer to Figure 1 and Figure 2 In this embodiment, a heat-insulating assembly is provided around the condensate branch pipe 6 and the outgoing oil passage 3. The heat-insulating assembly includes a first heat-insulating sleeve 7, a second heat-insulating sleeve 8, and a first locking member 9. The first heat-insulating sleeve 7 and the second heat-insulating sleeve 8 respectively wrap around the periphery of the condensate branch pipe 6 and the periphery of the outgoing oil passage 3. Both the first heat-insulating sleeve 7 and the second heat-insulating sleeve 8 have a semi-circular structure, and multiple first locking blocks are symmetrically installed on both outer sides of the first heat-insulating sleeve 7 and the second heat-insulating sleeve 8. Each of these first locking blocks has a first locking hole.

[0026] When the first insulation sleeve 7 and the second insulation sleeve 8 are respectively wrapped around the outer periphery of the condensate branch pipe 6 and the outer periphery of the outgoing oil passage 3, the first insulation sleeve 7 and the second insulation sleeve 8 abut against each other, so that the first locking block on the first insulation sleeve 7 and the first locking block on the second insulation sleeve 8 correspond to each other and abut against each other, so that the first locking holes on the two corresponding and abutting first locking blocks are interconnected.

[0027] Meanwhile, the first locking member 9 is a locking structure in which the first locking bolt and the first locking nut are threadedly connected to each other, and multiple first locking bolts and first locking nuts are provided. The number of first locking bolts and first locking nuts is half the number of the first locking blocks. The first locking bolt cooperates with the first locking hole, so that the first locking bolt passes through the two first locking blocks simultaneously along the two interconnected first locking holes.

[0028] Then, by screwing the first locking nut onto the first locking bolt, the first locking block on the first insulation sleeve 7 and the first locking block on the second insulation sleeve 8 can be fastened together, thereby making the first insulation sleeve 7 and the second insulation sleeve 8 securely locked around the condensate branch pipe 6 and the outgoing oil passage 3. This ensures that the condensate branch pipe 6 and the outgoing oil passage 3 can be firmly attached to each other, thereby improving the insulation effect.

[0029] Preferably, a first insulation cotton 10 is wrapped around both the outer periphery of the first insulation sleeve 7 and the second insulation sleeve 8. By setting the first insulation cotton 10, heat loss can be prevented, thereby further improving the insulation effect.

[0030] In addition, refer to Figure 1 and Figure 3 In this embodiment, a loop insulation component is provided around the condensate branch pipe 6 and the return pipeline oil passage 4. The loop insulation component includes a third insulation sleeve 11, a fourth insulation sleeve 12, and a second locking member 13. The third insulation sleeve 11 and the fourth insulation sleeve 12 respectively wrap around the periphery of the condensate branch pipe 6 and the periphery of the return pipeline oil passage 4. Both the third insulation sleeve 11 and the fourth insulation sleeve 12 have a semi-circular structure, and multiple second locking blocks are symmetrically installed on both outer sides of the third insulation sleeve 11 and the fourth insulation sleeve 12. Each of these second locking blocks has a second locking hole.

[0031] When the third insulation sleeve 11 and the fourth insulation sleeve 12 are respectively wrapped around the outer periphery of the condensate branch pipe 6 and the outer periphery of the return pipeline oil circuit 4, the third insulation sleeve 11 and the fourth insulation sleeve 12 abut against each other, so that the second locking block on the third insulation sleeve 11 and the second locking block on the fourth insulation sleeve 12 correspond to each other and abut against each other, so that the second locking holes on the two corresponding and abutting second locking blocks are interconnected.

[0032] Meanwhile, the second locking member 13 is a locking structure in which the second locking bolt and the second locking nut are threadedly connected to each other, and multiple second locking bolts and multiple second locking nuts are provided. The number of second locking bolts and multiple second locking nuts are half the number of the second locking blocks, and the second locking bolt cooperates with the second locking hole so that the second locking bolt passes through the two second locking blocks simultaneously along the two interconnected second locking holes.

[0033] Then, by screwing the second locking nut onto the second locking bolt, the second locking block on the third insulation sleeve 11 and the second locking block on the fourth insulation sleeve 12 can be fastened together, thereby making the third insulation sleeve 11 and the fourth insulation sleeve 12 securely locked around the condensate branch pipe 6 and the return pipeline oil circuit 4. This ensures that the condensate branch pipe 6 and the return pipeline oil circuit 4 can be firmly and tightly attached to each other, thereby improving the insulation effect.

[0034] Preferably, a second insulation cotton 14 is wrapped around both the third insulation sleeve 11 and the fourth insulation sleeve 12. By setting the second insulation cotton 14, heat loss can be prevented, thereby further improving the insulation effect.
