The utility model belongs to the technical field of chemical industry accident collecting pit, concretely relates to novel low temperature liquefied hydrocarbon accident collecting pit.
Background
The liquefied hydrocarbon is hydrocarbon liquid with vapor pressure of more than 0.1MPa at 15 ℃ and other similar liquids. The temperature of the liquefied hydrocarbon is extremely low when the liquefied hydrocarbon is vaporized at normal pressure, for example, the temperature of propylene reaches-47.5 ℃ when the propylene is vaporized at normal pressure, the temperature of propane reaches-45 ℃ and the temperature of ethylene reaches-100 ℃ when the ethylene is vaporized.
An emergency leakage collecting pool is also arranged on the liquefied natural gas and low-temperature liquefied hydrocarbon wharf according to the regulations of the design fire protection code of oil and gas chemical wharf (JTS158-2019) No. 6.1.3. The corresponding article explains that "the leakage of liquefied natural gas and cryogenic liquefied hydrocarbon may cause cryogenic influence on surrounding facilities and personnel, and therefore requires a collection tank for centralized disposal" as follows. Therefore, a liquefied hydrocarbon accident collecting tank is required to be provided in the liquefied hydrocarbon operation area.
In order to facilitate quick volatilization of leaked liquefied hydrocarbon, the liquefied hydrocarbon accident collection pool is in an open type, rainwater can enter the pool at ordinary times, and the liquefied hydrocarbon accident collection pool needs to be discharged completely in time in order not to influence accident liquid collection. Therefore, a liquid collecting pit and a drain pipe (namely an emptying pipe) are arranged at the bottom of the accident pool, and a valve is arranged on the drain pipe and used for switching rain and sewage. The valve is easy to be eroded by seawater and damaged, the operation difficulty is high, although the valve can be set as an automatic control valve, the valve needs to be opened and closed periodically for ensuring the effectiveness of the valve, and once the valve is damaged, the maintenance is very difficult.
In view of the above, there is a need to develop and develop a method for solving the problems that the valve at the bottom of the wharf liquefied hydrocarbon accident collecting tank is easy to corrode and damage and difficult to maintain, and achieving the effects of simple operation and cost saving.
SUMMERY OF THE UTILITY MODEL
In view of the above, an object of the present invention is to provide a novel low temperature liquefied hydrocarbon accident collecting tank.
A novel low-temperature liquefied hydrocarbon accident collecting pool comprises a liquefied hydrocarbon accident collecting pool main body, a liquid collecting pit, a sleeve and a water seal pipe; the liquefied hydrocarbon accident collecting pool is characterized in that the liquid collecting pit is arranged at the bottom of the liquefied hydrocarbon accident collecting pool main body; the sleeve pipe is buried in the bottom in collection liquid hole, and the intercommunication collection liquid hole, the sleeve pipe is connected with the one end of water seal pipe, and the other end of water seal pipe is "U" type of falling, and the height that turns up flushes or is less than the top in collection liquid hole slightly with collection liquid hole top.
The novel low-temperature liquefied hydrocarbon accident collecting pool is characterized in that the liquefied hydrocarbon accident collecting pool main body is in an open type.
The novel low-temperature liquefied hydrocarbon accident collecting pool is characterized in that the joint of the sleeve and the water seal pipe is filled with non-combustible materials to prevent leakage.
When the liquid level of rainwater stored in the liquefied hydrocarbon accident collecting pool main body is higher than the highest point of the water seal pipe 4, the rainwater can be discharged through the sleeve and the water seal pipe in sequence, and only the accumulated water in the liquid collecting pit is reserved; when the accident state is met, a large amount of liquefied hydrocarbon leaks into the liquefied hydrocarbon accident collection pool main body, and collection and storage of leakage liquid are realized by automatically freezing and plugging accumulated water remaining in the liquid collection pit by utilizing the characteristic that the liquefied hydrocarbon is vaporized and absorbs heat to generate low temperature.
Compared with the prior art, the beneficial effects of the utility model reside in that:
1) the utility model discloses set up the liquid collection hole bottom accident pool major structure, the 'U' type water seal pipe that will connect turns up highly to set up to flush or low point slightly with the liquid collection hole, is convenient for put the rainwater hydrops in the accident pool major structure at ordinary times, only remains a little ponding in the liquid collection hole.
2) The utility model discloses utilize liquefied hydrocarbon self low temperature characteristic, when leaking the occurence of failure, volatilize in a large number and cause local low temperature, will collect the ponding solidification in the liquid pit in the twinkling of an eye and freeze for accident pool major structure bottom discharge port is automatic to be sealed, realizes leaking the collection and the storage of leakage liquid.
3) The utility model discloses simple structure, investment cost is low, avoids the routine maintenance demand, has better economic benefits and social.
