Abstract
Description
Technical Field
[0001] The present application relates to the technical field of garbage storage, and in particular to a temperature raising system for a garbage storage. Background Art
[0002] A garbage storage facility is a building within a waste incineration plant that is used to store garbage. During storage in the garbage storage facility, the garbage is fermented and dehydrated to reduce the water content in the garbage, allowing the garbage to burn more fully in the incinerator, thereby improving the combustion efficiency of the incinerator.
[0003] The fermentation and dehydration process of garbage in the garbage storage facility varies greatly with temperature. For example, when the temperature is high, the activity of microorganisms in the garbage is higher and the garbage ferments more fully. When the temperature is below 10°C, the activity of microorganisms in the garbage decreases, causing the fermentation rate to drop and the garbage fermentation to be incomplete. When the temperature is below 5°C, the garbage stops fermenting completely.
[0004] Therefore, in the spring, autumn or winter when the temperature is lower, the ambient temperature in the garbage storage is lower, so that the garbage in the garbage storage cannot be fully fermented, which in turn causes incomplete combustion of the garbage in the incinerator, affecting the combustion efficiency of the incinerator. Utility Model Content

[0025] See also Figure 1 A garbage storage temperature raising system provided in an embodiment of the present application includes a garbage storage 10, a heat exchange device 11 and a booster fan 12. A garbage storage air outlet 13 and a garbage storage air inlet 14 are arranged on the outer wall of the garbage storage 10. The garbage storage air outlet 13 is connected to the air inlet of the heat exchange device 11, the air outlet of the heat exchange device 11 is connected to the air inlet of the booster fan 12, and the air outlet of the booster fan 12 is connected to the garbage storage air inlet 14.
[0026] The garbage storage temperature raising system provided in the embodiment of the present application is used to raise the ambient temperature in the garbage storage 10 in spring, autumn or winter when the temperature is relatively low, so that the ambient temperature in the garbage storage 10 reaches the temperature at which the garbage is fully fermented. The process of raising the ambient temperature in the garbage storage 10 by using the garbage storage temperature raising system provided in the embodiment of the present application is as follows: starting the booster fan 12, and continuously conveying the heat medium used to heat the air in the heat exchange device 11, the booster fan 12 provides power to convey the cold air in the garbage storage 10 to the heat exchange device 11 through the garbage storage outlet 13, the cold air is heated up to form hot air after heat exchange with the heat medium in the heat exchange device 11, and the hot air is then conveyed to the garbage storage 10 through the booster fan 12 and the garbage storage air inlet 14 in turn, and the cycle is repeated to raise the ambient temperature in the garbage storage 10. Among them, the heat medium can be heat transfer oil, steam, hot water, hot flue gas, etc., which is not specifically limited here.
[0027] Therefore, the garbage storage temperature raising system provided in the embodiment of the present application can use the booster fan 12 to transport the air in the garbage storage 10 to the heat exchange device 11 for heating and then transport it to the garbage storage 10, so as to increase the ambient temperature in the garbage storage 10, so that the garbage can be fully fermented in the garbage storage 10, and the subsequent garbage can be fully burned in the incinerator, thereby improving the combustion efficiency of the incinerator. Since the heating air source in the garbage storage 10 is taken from the air in the garbage storage 10, when the garbage storage temperature raising system is working, the garbage storage 10 can be placed in a slightly negative pressure state, thereby preventing the odor in the garbage storage 10 from leaking out and avoiding affecting the external environment.
[0028] See also Figure 1 The air outlet 13 of the garbage storage is connected to the air inlet of the heat exchange device 11 through the first pipe 21, the air outlet of the heat exchange device 11 is connected to the air inlet of the booster fan 12 through the second pipe 22, and the air outlet of the booster fan 12 is connected to the air inlet 14 of the garbage storage through the third pipe 23. In order to reduce the heat loss when the air is transported in the above pipes, a heat insulation structure is provided on the pipes between the garbage storage 10, the heat exchange device 11 and the booster fan 12.
[0029] See also Figure 1, the height of the garbage storage air outlet 13 is higher than the height of the garbage storage air inlet 14. Exemplarily, the garbage storage air outlet 13 is arranged at the upper end of the outer wall, and the garbage storage air inlet 14 is arranged at the lower end of the outer wall. Among them, the garbage storage air outlet 13 and the garbage storage air inlet 14 can be arranged on the same outer wall, and can also be arranged on different outer walls. By setting the above structure, when the hot air enters the garbage storage 10 from the garbage storage air inlet 14, the hot air also exchanges heat with the cold air in the garbage storage 10 while rising, so as to improve the heating efficiency. In order to further improve the heating efficiency, the garbage storage air inlet 14 includes at least two. By setting at least two garbage storage air inlets 14, hot air can be transported from different positions of the garbage storage 10 to the garbage storage 10, so as to improve the heating efficiency.
[0030] The garbage storage temperature raising system provided in the embodiment of the present application is mainly used to operate in part of the spring and autumn and in winter to raise the ambient temperature in the garbage storage 10. In summer, since the ambient temperature in the garbage storage 10 reaches the temperature at which the garbage is fully fermented, the garbage storage temperature raising system provided in the embodiment of the present application does not need to be operated in summer. Of course, in summer, the staff can also inspect and maintain the garbage storage temperature raising system in a shutdown state.
[0031] In summer, in order to prevent the air in the garbage storage 10 from entering the garbage storage temperature raising system in a shutdown state and causing corrosion to the pipes and equipment in the system, see Figure 1 , a blocking cover plate 15 is provided at the air outlet 13 and the air inlet 14 of the garbage storage. When the temperature raising system of the garbage storage is in a shutdown state, the air outlet 13 and the air inlet 14 of the garbage storage can be blocked by the blocking cover plate 15 to prevent the air in the garbage storage from entering the temperature raising system of the garbage storage and causing corrosion to the pipes and equipment in the system, thereby improving the service life of the temperature raising system of the garbage storage. Exemplarily, one end of the blocking cover plate 15 is hinged to the outer wall, and the other end of the blocking cover plate 15 is detachably connected to the outer wall. For example, the other end of the blocking cover plate 15 is detachably connected to the outer wall by a bolt structure. Of course, the blocking cover plate 15 can also be connected to the outer wall by other structures, which are not specifically limited here.
[0032] The heat exchange device 11 may be a shell and tube heat exchanger, the tube side of the shell and tube heat exchanger is used to transport the air in the garbage storage 10, and the shell side of the shell and tube heat exchanger is used to transport the heat medium.
[0033] See also Figure 1In order to improve the heat exchange efficiency, the heat exchange device 11 includes a steam-air heat exchanger; the steam-air heat exchanger is provided with an air inlet and an air outlet connected, and a steam inlet and a cooling water outlet connected; the air inlet of the steam-air heat exchanger forms the air inlet of the heat exchange device 11, and the air outlet of the steam-air heat exchanger forms the air outlet of the heat exchange device 11. During operation, cold air is transported from the air inlet to the steam-air heat exchanger, and steam is transported from the steam inlet to the steam-air heat exchanger. After the steam and the cold air exchange heat in the steam-air heat exchanger, the steam temperature is reduced to form cooling water, which is transported away from the cooling water outlet, and the cold air temperature is increased to form hot air, which is transported away from the air outlet.
[0034] Exemplarily, the steam inlet of the steam-air heat exchanger is connected to the steam outlet of the flash tank 17, and the cooling water outlet of the steam-air heat exchanger is connected to the preheater 18. The flash tank 17 is used to store the saturated steam generated by the boiler, and the preheater 18 is used to store and preheat the cooling water. By providing the flash tank 17 and the preheater 18, the saturated steam in the flash tank 17 can be used as a heating source, and the preheater 18 can be used to heat the cooling water and reuse it.
[0035] When the garbage storage temperature raising system is in shutdown state, in order to prevent the air in the garbage storage 10 from entering the steam-air heat exchanger and causing corrosion to its internal structure, see Figure 1 The air inlet and the air outlet of the steam-air heat exchanger are both equipped with shut-off valves 16. When the garbage storage temperature raising system is in shutdown state, the shut-off valve 16 can be closed to prevent the air in the garbage storage from entering the steam-air heat exchanger and corroding its internal structure, thereby increasing the service life of the steam-air heat exchanger. Exemplarily, the shut-off valve 16 can be an existing gate valve, ball valve, etc., or other structures that have a shut-off function, which are not specifically limited here.
[0036] When the garbage storage heating system is in shutdown state in summer, dry and clean air can be used to replace the residual garbage storage air in the garbage storage heating system to reduce the corrosion of the air to the system and further increase the service life of the garbage storage heating system. Figure 1 A spare pipe 19 connected to the inner cavity of the heat exchange device 11 is provided on the pipeline between the air outlet 13 of the garbage storage and the air inlet of the heat exchange device 11, and a spare valve 20 is provided on the spare pipe 19. The spare pipe 19 is arranged outside the garbage storage 10 and can be used to transport dry and clean air to the first pipeline 21.
[0037] The standby valve 20 is in a normally closed state. When the air remaining in the garbage storage temperature raising system needs to be replaced, the standby valve 20 is opened, the air outlet 13 of the garbage storage is blocked, and the booster fan 12 is started. Dry and clean air enters the first pipeline 21 from the standby pipe 19, and enters the garbage storage 10 through the heat exchange device 11, the second pipeline 22, the booster fan 12, the third pipeline 23 and the garbage storage air inlet 14 in sequence. In this process, the air remaining in the garbage storage temperature raising system is replaced. When the garbage storage air in the garbage storage temperature raising system is replaced, the booster fan 12 is closed, the standby valve 20 is closed, the garbage storage air inlet 14 is blocked, and the shut-off valve 16 is closed.
[0038] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Based on the technical essence of the present application and within the spirit and principles of the present application, any simple modification, equivalent replacement and improvement of the above embodiments shall still fall within the protection scope of the technical solution of the present application.
