and the first branch cylinder is communicated with at least one boiler, and when the steam pressure is less than a set pressure threshold value, the first branch cylinder is controlled to be communicated with a standby boiler so as to gradually increase the steam pressure.
In practical application, as shown in fig. 2, if the amount of steam for vacuum moisture regaining is not increased, the steam supply process flow is as follows: boiler 16 and boiler 23 may represent multiple boilers, and may operate one or both, and if boiler 16 is operating, steam generated by boiler 16 is introduced into steam splitting cylinder 26 via valve 24, conduit 25, and valve 28. If the boiler 23 is operated, the steam generated by the boiler 23 enters the branch cylinder 26 through the valve 21, the pipeline 22 and the valve 29. When steam is supplied to the silk making workshop, steam in the steam-dividing cylinder 26 can enter the steam-dividing cylinder 65 of the silk making workshop through the valve 30, the pipeline 27, the pipeline 76 and the valve 75, the steam in the steam-dividing cylinder 65 can enter the vacuum moisture regain 71 through the valve 74 and the pipeline 70 respectively, and then enters the stem silk thread 69 through the valve 73 and the pipeline 68 and enters the leaf silk thread 67 through the valve 72 and the pipeline 66. When steam is supplied to a whole plant air conditioner, steam in the steam distribution cylinder 26 can enter the air conditioning steam distribution cylinder 34 through the valve 31, the pipeline 32 and the valve 33, the steam in the steam distribution cylinder 34 can enter the heater 46 in the heat storage 44 through the valve 38, the pipeline 37, the pipeline 83 and the electric valve 82, the steam heats water in the heat storage 44 through the heater 46, and the heater 46 can enable the water to be heated quickly and has low noise. The water in the heat accumulator 44 can be heated to high-temperature saturated water with the same pressure and temperature as the steam, when the water in the heat accumulator 44 reaches a saturated state, the water in the heat accumulator 44 continuously evaporates to form steam, the steam enters the air-conditioning indoor air-distributing cylinder 53 through the electric valve 79, the pipeline 78, the pipeline 60 and the valve 59, and the steam in the air-conditioning indoor air-distributing cylinder 53 can be decompressed to 3bar through the valve 54 and the pipeline 56 and enters the air-conditioning heater 64 through the decompression valve 63; the steam in the steam-distributing cylinder 53 can be reduced to 2bar through a valve 55 and a pipeline 57 by a pressure reducing valve 61 and enters a humidifier 62 of an air conditioner.
When the steam consumption for vacuum moisture regain in a tobacco shred manufacturing workshop is suddenly increased or the steam consumption of stem threads and leaf threads is suddenly fluctuated, if only the boiler 16 is in operation at the moment and the operation load of the boiler 16 is already large, the steam generated by the boiler 16 cannot meet the steam consumption, and if the heat accumulator 44 is not used, the other boiler 23 is started, but because the steam consumption time of the vacuum moisture regain 71 is short, the boiler 23 may not be started to supply steam normally or just started to operate for a while, the steam consumption of the leaf thread segments and the stem thread segments is stopped, the steam consumption of the leaf thread segments and the stem thread segments is fluctuated sometimes, and when the steam consumption of the boiler 16 cannot meet the steam consumption, the steam pressure is reduced, so that the normal process production is possibly influenced. This may cause frequent start and stop of the boilers 23 or increase of the operation of at least one boiler 23 in order to prevent the steam pressure from being lowered, and when the amount of steam to be used is not large, both the boilers are operated at low load, the operation efficiency of the boilers is low, and energy is wasted. Because the steam supply pressure of the boiler is basically equal to the steam pressure for vacuum moisture regain, leaf threads, stem threads and the like of a silk making workshop, a heat accumulator cannot be installed in a steam supply pipeline system of the silk making workshop. Because the pressure of the steam for heating and humidifying the air conditioner is lower, the heat accumulator 44 is arranged in the steam supply pipeline system for the air conditioner, when the steam consumption for the production of the silk making workshop is suddenly increased, the pressure sensor 18 on the branch cylinder 26 monitors that the steam pressure is reduced to a certain value, the steam inlet electric valve 82 on the heat accumulator 44 is closed or turned off, at the moment, the steam generated by the boiler 16 stops supplying the steam for the air conditioner or reduces the steam supply for the air conditioner, all or most of the steam generated by the boiler 16 is used for supplying the silk making workshop, the standby boiler 23 is internally provided with high-temperature and high-pressure saturated water and steam although not started, and if the steam pressure of the pipeline system is reduced a little, the boiler 23 can release a part of the steam, so that the phenomenon that the pressure fluctuation of the steam supplied to the silk making workshop is too large is avoided. At the moment, the heat accumulator 44 is mainly used for supplying steam to the air conditioner, because the steam pressure of the heater 64 and the humidifier 62 of the air conditioner is very low, a large amount of high-temperature and high-pressure saturated water is stored in the heat accumulator 44, and a large amount of steam released by the saturated water in the heat accumulator 44 enters the air-conditioning chamber branch cylinder 53 through the electric valve 79, the pipeline 78, the pipeline 60 and the valve 59 to be used by the heater 64 and the humidifier 62 of the air conditioner. After a few minutes, when the steam consumption of the filament making workshop is reduced, the steam generated by the boiler 16 can meet the steam consumption of filament making production and air conditioning, the pressure sensor 18 on the steam distributing cylinder 26 detects that the steam pressure rises to a certain value, the steam inlet electric valve 82 on the heat accumulator 44 is opened, a part of the steam generated by the boiler 16 enters the steam distributing cylinder 34 through the steam distributing cylinder 26, then enters the heat accumulator 44 through the valve 38, the pipeline 37 and the pipeline 83 and then enters the heat accumulator 44 through the steam inlet electric valve 82 to heat water in the heat accumulator 44, meanwhile, the heat accumulator 44 continuously supplies steam to the air conditioner heater 64 and the humidifier 62, and the heat accumulator is gradually heated to a high-temperature and high-pressure state. At this time, a small amount of steam generated by the boiler 16 enters the boiler 23 through the steam distributing cylinder 26, the valve 29, the pipeline 22 and the valve 21, so that the interior of the boiler 23 is in a high-temperature and high-pressure state, and thus the heat accumulator 44 and the boiler 23 also continuously release and fill steam along with the high and low changes of the steam consumption of the silk making workshop, thereby continuously and stably supplying steam pressure to the silk making workshop.
The branch cylinder 34 is provided with an external pipeline 39 connected with a steam pipeline of a heating power company, and because the steam cost of the heating power company is lower than that of the steam generated by a boiler, when the heating power company supplies steam in winter, a valve 40 is opened, and the steam of the heating power company can enter the branch cylinder 34 through the external pipeline 39. Thereby forming a flexible steam supply method: in the first method, when the steam pressure of the heating power company is low, the heating power company supplies air conditioning steam, the boiler supplies production steam for the filament manufacturing workshop, namely, the valve 33 and the valve 31 on the communication pipeline 32 between the steam distributing cylinder 34 and the steam distributing cylinder 26 are closed, and the steam of the heating power company can supply steam to the air conditioning heater 64 and the humidifier 62 through the steam distributing cylinder 34 and the steam distributing cylinder 53, and can also supply steam to the deaerating water tank 87, the deaerating water tank 108 and the heat accumulator 44. The boiler 16 only supplies steam for the vacuum moisture regain 71, the stem thread line 69 and the leaf thread line 67 of the shred making workshop through the steam distributing cylinder 26 and the steam distributing cylinder 65, so that the boiler 16 is specially used for producing steam for shred making, the steam pressure is stable even if the flow of the steam for production fluctuates, and the number of the boiler for starting can be greatly reduced. In the second method, when the steam pressure of the heating power company meets the requirement of the shred manufacturing production, the operation of all the boilers can be stopped, namely the boiler 16 and the boiler 23 are stopped, and the steam of the heating power company is used for steam for a shred manufacturing workshop and an air conditioner. Steam of a thermal company enters the steam-distributing cylinder 34 through the external pipeline 39, then enters the steam-distributing cylinder 26 through the steam-distributing cylinder 34 and the communicating pipeline 32, then enters the steam-distributing cylinder 65 through the steam-distributing cylinder 26, the valve 30, the pipeline 76 of the pipeline 27 and the like, and then is used for steam of the vacuum moisture regain 71, the cut stem line 69 and the cut leaf line 67 of the silk-making workshop. Meanwhile, steam of a thermal power company can enter the branch cylinder 53 from the branch cylinder 34 through the valve 38, the pipeline 37 and the like to supply steam to the air conditioner heater 64 and the humidifier 62, and can also supply steam to the deoxygenation water tank 87, the deoxygenation water tank 108 and the heat accumulator 44 through the pipeline 35, the pipeline 85 and the like, at this time, the heat accumulator 44 can balance pressure fluctuation of steam used in the wire making workshop, and the boiler 16 and the boiler 23 can also be equivalent to a heat accumulator to assist in balancing pressure fluctuation of the wire making workshop. And the third method is that when the heating power company does not supply steam, the whole plant wire-making workshop, the air conditioner, the deoxidizing water tank, the heat accumulator and the like are supplied with steam by the boiler 16 or the boiler 23.
The liquid level meter 43 is installed on the heat accumulator, the liquid level sensor 42 is also installed on the liquid level meter 43, if the water level in the heat accumulator 44 is reduced to a low water level, the liquid level sensor 42 sends a signal, the water pump 11 is started, the softened water in the soft water tank 1 sequentially enters the heat accumulator 44 through the valve 10, the water pump 11, the check valve 12, the valve 13, the pipeline 17, the pipeline 41 and the valve 80 for water supplement, and when the water level in the heat accumulator 44 reaches a normal water level, the water pump 11 stops running. If the water level in the accumulator reaches the ultra-high overflow water level, the pressure in the accumulator 44 is high, and the excess water flows into the deoxygenating water tank 108 through the valve 50, the drain valve 51, the check valve 52, the pipeline 49, the pipeline 45 and the pipeline 110 in sequence, and then flows into the deoxygenating water tank 87 through the pipeline 101 and the valve 102, and flows into the deoxygenating water tank 108 through the pipeline 94 and the valve 93, so that the hot water is saved. The accumulator is also drained through valve 47 and electrically operated valve 48. In order to prevent oxygen in the softened water in the heat accumulator from corroding the heat accumulator and a steam pipeline system, the temperature of the water in the heat accumulator exceeds 100 ℃, oxygen and partial hot steam in the heat accumulator are decompressed by a valve 81, a pipeline 84 and a pipeline 85 through a decompression valve 86, and then respectively enter a heater 88 in a deoxygenating water tank 87 through a pipeline 95 and a heating electric valve 96 to heat soft water to remove oxygen in the soft water, and enter a heater 107 in a deoxygenating water tank 108 through a pipeline 99 and a heating electric valve 100 to heat soft water to remove oxygen in the soft water. The oxygen in the deaerating water tank 87 and the deaerating water tank 108 is discharged to the outside of the room through the diffusing pipe 92 on the upper portion of the deaerating head 91 and the diffusing pipe 103 on the upper portion of the deaerating head 104, respectively, so that the heat accumulator 44 can deaerate the water in the deaerating water tank while deaerating and discharging the oxygen by itself, and the heat energy is saved. When the heat accumulator 44 is in failure, overhauled or the heat supply amount to the deaerating water tank is insufficient, the steam in the branch cylinder 34 can enter the pipeline 85 through the valve 36 and the pipeline 35, then enters the deaerating water tank 87 through the heating electric valve 96 and enters the deaerating water tank 108 through the heating electric valve 100 to heat and deaerate the softened water after being decompressed by the decompression valve 86.
When the liquid level of the deoxygenation water tank 108 or the deoxygenation water tank 87 reaches a low water level and water needs to be supplemented, softened water in the soft water tank 1 passes through the valve 2, the water pump 3, the check valve 4, the valve 5 and the pipeline 109 and then can be respectively supplemented with water for the deoxygenation water tank 108 through the pipeline 106 and the water supplementing electric valve 105 or supplemented with water for the deoxygenation water tank 87 through the pipeline 90 and the water supplementing electric valve 89. When the boiler 16 is low in water level and needs water supplement, water in the deoxygenation water tank 108 is deoxygenated and then enters the boiler 16 through the valve 111, the water pump 112, the check valve 113, the valve 114, the pipeline 14 and the valve 15; when the boiler 23 is low in water level and needs to be supplemented with water, the water in the deoxygenation water tank 87 is deoxygenated and then enters the boiler 23 through the valve 6, the water pump 7, the check valve 8, the valve 9, the pipeline 19 and the valve 20. The upper communication pipeline 97 and the upper communication valve 98 are arranged at the upper parts of the deoxygenation water tank 108 and the deoxygenation water tank 87, and the lower communication pipeline 116 and the lower communication valve 115 are arranged at the lower parts of the deoxygenation water tank 108 and the deoxygenation water tank 87, so that the two deoxygenation water tanks can be mutually standby, and even if faults such as a water inlet electric valve, a steam inlet electric valve or a liquid level meter on one deoxygenation water tank occur, the water supplement, the heating and the boiler utilization of the deoxygenation water tank cannot be influenced. The electric valves are all connected in series with manual valves, if the water-supplementing electric valve 89 of the deoxygenation water tank 87 fails or the heating electric valve 96 or the liquid level meter fails, the deoxygenation water tank 87 is insufficient in water supplement, or the deoxygenation water tank 87 cannot be heated and deoxygenated, or the liquid level cannot be normally displayed, at this time, the water-supplementing manual valve and the water-supplementing electric valve 96 of the deoxygenation water tank 87 can be even closed, because the lower communicating pipe 116 and the lower communicating valve 115 are installed between the deoxygenation water tank 108 and the deoxygenation water tank 87, water in the deoxygenation water tank 108 can be supplemented to the deoxygenation water tank 87 through the lower communicating pipe 116 and the lower communicating valve 115, and because the water inlet valve of the deoxygenation water tank 87 is closed at this time, water supplemented to the deoxygenation. Because the upper communicating pipeline 97 and the upper communicating valve 98 are arranged between the deoxygenation water tank 108 and the deoxygenation water tank 87, the pressures of the two deoxygenation water tanks are balanced, so that the liquid levels of the two deoxygenation water tanks are not different due to different pressures after heating, the liquid levels of the two deoxygenation water tanks are consistent, and the liquid levels of the deoxygenation water tank 108 and the deoxygenation water tank 87 can be known through a liquid level meter or a liquid level sensor of the deoxygenation water tank 108. Therefore, at this time, although some accessories of the deaerating water tank 87 are out of order, the deaerating water tank 87 does not affect the water supply to the boiler 23.
The pressure sensor 58 is installed on the heat accumulator 44, the steam inlet pipeline 83 and the steam outlet pipeline 78 of the heat accumulator 44 are also installed with a bypass electric valve 77, when the pressure sensor 53 detects that the pressure in the heat accumulator 44 is too low, which indicates that the steam supply amount of the air conditioner heater 64 and the humidifier 62 by the heat accumulator 44 is insufficient, the bypass electric valve 77 is fully opened or partially opened, the steam of the air-dividing cylinder 34 can directly enter the pipeline 60 through the bypass electric valve 77 after passing through the valve 38 and the pipeline 37 and is then conveyed to the air-conditioning chamber air-dividing cylinder 53 through the valve 59, so that the steam is supplied to the air conditioner heater 64 and the humidifier 62. Even if the heat accumulator 44 is in failure or overhauled, the steam inlet electric valve 82 and the steam outlet electric valve 79 of the heat accumulator are closed, the steam of the air-distributing cylinder 34 can still directly enter the pipeline 60 through the bypass electric valve 77 after passing through the valve 38 and the pipeline 37 and is conveyed to the air-conditioning chamber air-distributing cylinder 53 through the valve 59, and then the steam is supplied to the heater 64 and the humidifier 62 of the air conditioner, so that the influence on the steam for the air conditioner is avoided.
