Description
Technical Field
The utility model relates to a propylene chemical industry technical field especially relates to a propylene storage tank water injection system.
Background
The propylene spherical tank is filled with a certain amount of propylene liquid under a normal state. Since propylene is gaseous at normal pressure, when leakage occurs at the bottom of the propylene spherical tank, propylene liquid leaks out of the leakage point, and the leakage of propylene may cause the local temperature of the propylene spherical tank to be too low or cause combustion or even explosion when exposed to fire. In order to prevent local temperature from being too low or causing explosion accidents when the bottom of the propylene spherical tank leaks, a water injection device needs to be arranged on the propylene spherical tank. Because the density of water is greater than that of propylene liquid, the water can seal the leakage point after water injection, and the leaked liquid is water and not propylene, thereby fundamentally reducing the occurrence of accidents.
In the prior art, although a plurality of propylene spherical tank water injection devices are provided with special water injection pumps, the probability of leakage of the propylene spherical tanks is very low, so that the water injection pumps are placed for years and are not frequently used, and the reliability of the water injection pumps is reduced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a propylene storage tank water injection system.
The utility model adopts the technical proposal that:
the utility model provides a propylene storage tank water injection system, includes the propylene storage tank, and the bottom of propylene storage tank is connected with the water injection pump through water injection pipeline one, and the water injection pump is connected with the fire-fighting water pond, and the fire-fighting water pond is connected with the circulating water pond, and the water injection pump still is connected with the circulating water pond through water injection pipeline two, and the top of propylene storage tank is connected with the propylene pipeline.
And a second check valve is arranged on the second water injection pipeline, and the flow direction of the second check valve flows from the water injection pump to the circulating water tank.
And a first check valve which flows from the fire pool to the water injection pump is arranged on the first water injection pipeline.
The capacity of the circulating water tank is greater than that of the fire-fighting water tank, the capacity of the circulating water tank is four times of that of the fire-fighting water tank, and the water consumption of the propylene storage tank is one ninth of that of the fire-fighting water tank.
