Embodiment

[0029] Such as figure 1 As shown, an emergency treatment device for liquid ammonia storage tank leakage includes a detection mechanism, a spray mechanism and a sleeve 6 . The sleeve 6 is set outside the liquid ammonia storage tank 5, the right end of the sleeve 6 is sealed and the left end is open, combined with figure 2 It can be seen that four partitions 10 are welded axially in the sleeve 6, the length of the partitions 10 is the same as that of the sleeve 6, the four partitions 10 are evenly distributed in the sleeve 6, and the four partitions 10 are free The ends are all rotatably equipped with some pulleys (not shown in the figure), and the pulleys can slide along the liquid ammonia storage tank 5 outer walls. Four partitions 10 divide the space between the sleeve 6 and the liquid ammonia storage tank 5 into four sealing cavities 11, each of which is equipped with an arc-shaped air bag 9 in cross section, and the air bag 9 is glued to the air bag. Connected and fixed ...

Abstract

The invention relates to the technical field of liquid ammonia safety protection, in particular to an emergency treatment device for the leakage of a liquid ammonia storage tank. The emergency treatment device comprises a detection mechanism for detecting ammonia gas and a spraying mechanism for diluting the ammonia gas, and the emergency treatment device further comprises a sleeve sleeved outside the liquid ammonia storage tank, one end of the sleeve is sealed, the other end of the sleeve is open, and a plurality of partition plates are axially arranged in the sleeve. The free ends of the partition plates are in sliding connection with the surface of the liquid ammonia storage tank, the partition plates divide the space between the sleeve and the liquid ammonia storage tank into a plurality of blocking cavities, an air bag is arranged in each blocking cavity, the air bags are fixed to the sleeve, each air bag communicates with an air pump, and the air pumps are used for inflating and deflating the air bags; and the detection mechanism comprises an ammonia gas detector, the ammonia gas detector is arranged on the face, close to the liquid ammonia storage tank, of the air bag, the ammonia gas detector is electrically connected with a controller, the controller is electrically connected with an alarm, and the controller is further electrically connected with the spraying mechanism and the air pump. According to the emergency treatment device, the air bags are inflated to block a leakage area, and further leakage of ammonia gas is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of liquid ammonia safety protection, in particular to an emergency treatment device for leakage of a liquid ammonia storage tank. Background technique [0002] Liquid ammonia is a colorless liquid with a strong pungent smell. Ammonia is in a gaseous state at room temperature. It is easily soluble in water, ethanol, etc. It is toxic and highly flammable. It can be mixed with air to form an explosive mixture. Cause combustion and explosion. For the convenience of transportation and storage, in the prior art, gaseous ammonia is usually pressurized or cooled to obtain liquid ammonia, which is then stored in a liquid ammonia storage tank. [0003] In the production, transportation, storage and use of liquid ammonia storage tanks, damage to pipes, valves, and storage tanks often occurs, resulting in leakage of liquid ammonia. Due to the high storage pressure of liquid ammonia, the leaked liquid ammonia will quick...
