Technical Field

[0001] The utility model relates to the technical field of anti-leakage devices, in particular to an anti-leakage device for a thermal power plant. Background Art

[0002] Ammonia plays a role in denitrifying exhaust gas during thermal power generation. For this reason, existing thermal power plants generally build liquid ammonia stations. However, this building also has certain safety hazards in actual use, namely liquid ammonia leakage. The current leakage prevention measures adopted in liquid ammonia stations are to use the principle that ammonia is highly soluble in water, and send the leaked ammonia into the water in the water tank, where the ammonia is absorbed by the water in the water tank.

[0003] In the prior art, when the liquid ammonia station of a thermal power plant sends the leaked ammonia into a water storage tank and mixes it with water for absorption, the absorption efficiency of the ammonia is not high due to the slow flow of water in the water storage tank; and after the ammonia is sent into the water transfer tank, the ammonia that is not mixed with water in time will float to the water surface through bubbles and accumulate in the water storage tank.

[0004] Therefore, a leakage prevention device for a thermal power plant is proposed to solve the above problems. Utility Model Content

After the bidirectional motor is started, it drives the threaded rod to rotate left and right, and synchronously drives the toggle plate to move forward and backward to toggle the water inside the water reservoir, so that the mixing efficiency is accelerated after the ammonia enters the water reservoir, thereby improving the absorption of ammonia.
