Detailed Description
The utility model will be further described with reference to the drawings and specific examples to aid in understanding the context of the utility model. The method used in the utility model is a conventional method unless specified otherwise; the raw materials and devices used, unless otherwise specified, are all conventional commercial products.
As shown in fig. 1-2, the utility model provides a liquid level alarm mechanism of a marine desulfurizing tower, which is arranged on the side wall of a desulfurizing tower 1. Specifically, the side wall of the desulfurizing tower 1 is sequentially communicated with a high-level communicating pipe 2 and a low-level communicating pipe 3 from top to bottom in the vertical direction, and the high-level communicating pipe 2 and the low-level communicating pipe 3 are connected to the side wall of the desulfurizing tower 1 through a flange 21. The other ends of the high-level communicating pipe 2 and the low-level communicating pipe 3 are communicated with a liquid level monitoring pipe 4, and a double-floating ball liquid level switch 5 is arranged in the liquid level monitoring pipe 4. The double-floating ball liquid level switch 5 is vertically and hermetically arranged at the top of the liquid level monitoring pipe 4 through a flange 21. The double-floating-ball liquid level switch is a commercial product, an upper floating ball limit 51, a lower floating ball limit 52 and a zero-position movable stop ring 53 are sequentially arranged on the inserted link from top to bottom, a lower floating ball 55 is arranged between the zero-position movable stop ring 53 and the lower floating ball limit 52, and an upper floating ball 54 is arranged between the lower floating ball limit 52 and the upper floating ball limit 51. When in use, the lower floating ball limit 52 is arranged at a proper height according to the actual condition of the desulfurizing tower, and the upper floating ball limit 51 is arranged at the communication position of the high-level communicating pipe 2 and the liquid level monitoring pipe 4. When the liquid level in the desulfurizing tower 1 rises and enters the liquid level monitoring tube 4 through the low-level communicating tube 3, the lower floating ball 55 rises to the lower floating ball limit 52 along with the liquid level, the lower floating ball 55 triggers the magnetic reed switch to enable the line to be communicated and trigger the electrifying, the double-floating ball liquid level switch 5 sends out a signal alarm and transmits the signal to the far-end control screen to prompt manual intervention; if the manual intervention is not performed in time, the liquid level in the desulfurizing tower 1 continuously rises, the upper floating ball 54 triggers an electrifying alarm when rising to the upper floating ball limit 51 along with the liquid level, and meanwhile, the desulfurizing system is stopped for protection, so that accidents caused by continuous rising of the liquid level are avoided.
The high-level communicating pipe 2 and the low-level communicating pipe 3 are respectively provided with a steady flow orifice plate 6, and the steady flow orifice plates 6 are provided with steady flow orifices 61. The steady flow pore plate 6 can play a role in stabilizing the flow of the desulfurization flue gas when the desulfurization tower 1 is in normal operation, so that particles such as soot in the flue gas are not easy to enter the liquid level monitoring pipe 4, and the influence on a liquid level switch is avoided; on the other hand, under severe weather conditions, when the ship is swayed severely, the steady flow orifice plate 6 can also prevent the strong impact of accumulated water in the desulfurizing tower 1, thereby causing false alarm of a liquid level switch and even system shutdown.
The bottom of the steady flow pore plate 6 is also provided with a reflux port 62, the reflux port 62 prevents accumulated water from staying in the high-level communicating pipe 2 and the low-level communicating pipe 3 to cause corrosion and ash aggregation and solidification, and meanwhile, ash can be naturally refluxed and entrained into the desulfurizing tower 1 along with water flow to be discharged when the accumulated water is refluxed.
The high-level communicating pipe 2 and the low-level communicating pipe 3 are internally provided with an air blowing mechanism 7, and the air blowing mechanism 7 is arranged on one side of the steady flow pore plate 6, which is close to the liquid level monitoring pipe 4. The blowing mechanism 7 is connected with the air pump, can utilize the high-flow impact of compressed air to realize the function of sweeping the stubborn dust deposit, and can be matched with a valve to realize automatic blowing.
The working principle of the utility model is as follows:
along with the flue gas desulfurization, accumulated water is generated in the desulfurizing tower 1, and in the liquid level rising process, the accumulated water firstly enters the liquid level monitoring pipe 4 through the low-level communicating pipe 3, and at the moment, the high-level communicating pipe 2 plays a role in ventilation, so that the liquid levels in the desulfurizing tower 1 and the liquid level monitoring pipe 4 are kept completely consistent. When the liquid level continuously rises to the position of the lower floating ball 55, the lower floating ball 55 rises together with the liquid level, and when the lower floating ball 55 reaches the position of the lower floating ball limit 52, the liquid level switch sends out a signal alarm. If the liquid level continues to rise to reach the position of the upper floating ball 54, the upper floating ball 54 can trigger a high-level alarm signal after reaching the upper floating ball limit 51 along with the rise of the liquid level, and the desulfurization system stops for protection.
The utility model has simple structure, and adopts one liquid level switch to play the roles of low liquid level alarming and high liquid level stopping protection which can be realized by two tuning fork switches of the traditional device by arranging the low-level communicating pipe 3 and the high-level communicating pipe 2. And particle matters such as ash in the flue gas are not easy to enter the liquid level monitoring tube 4 by arranging the steady flow pore plate 6, so that the influence on a liquid level switch is avoided; meanwhile, when the ship is severely rocked, the liquid level switch false alarm and even system shutdown caused by strong impact of accumulated water in the desulfurizing tower 1 are avoided, and the method can be widely applied to the desulfurizing tower for the ship.
