Passive automatic temperature decrease control system for oil tank

Abstract

The invention relates to a passive automatic temperature decrease control system for an oil tank, belonging to the field of the manufacturing and installing of automatic temperature decrease equipment system. The passive automatic temperature decrease control system for the oil tank mainly comprises a temperature sensing linkage mechanism, a spraying head, a linkage pilot valve, a water flow filter, a pilot opening and closing valve, an antifreeze drain valve and a water system. The passive automatic temperature decrease control system for the oil tank is characterized in that the temperature sensing linkage mechanism comprises a thermosensitive thrust component, a return spring and a retaining ring, the retaining ring is fixedly connected with a linkage steel wire which penetrates through the thermosensitive thrust component, when the temperature on the top of the oil tank exceeds the set value, the pilot opening and closing valve is opened, the temperature decreasing water is sprayed out, and when the temperature decreases, the spraying of the temperature decreasing water stops.

Description

technical field [0001] A passive automatic cooling control system for oil tanks belongs to the field of manufacturing and installation of cooling equipment. technical background [0002] Oil and gas tanks are now spread all over urban and rural areas. In the hot summer, the cooling of oil and gas tanks has always been a big problem for management personnel. According to the information released by authoritative departments, among the oil depot accidents, fire and explosion accounted for the total number of accidents. 42.5%, of which oil tank explosion accidents accounted for 25.6% of the total explosion accidents; the first solution in use is to install a "breathing valve" on the top of the oil and gas tanks. The increase in ambient temperature increases the volume, resulting in an increase in pressure, and the increased pressure pushes the internal diaphragm of the "breathing valve" open, releasing gasified oil and gas, reducing the pressure in the tank, and achieving the pur...

[0002] Oil and gas tanks are now spread all over urban and rural areas. In the hot summer, the cooling of oil and gas tanks has always been a big problem for management personnel. According to the information released by authoritative departments, among the oil depot accidents, fire and explosion accounted for the total number of accidents. 42.5%, of which oil tank explosion accidents accounted for 25.6% of the total explosion accidents; the first solution in use is to install a "breathing valve" on the top of the oil and gas tanks. The increase in ambient temperature increases the volume, resulting in an increase in pressure, and the increased pressure pushes the internal diaphragm of the "breathing valve" open, releasing gasified oil and gas, reducing the pressure in the tank, and achieving the purpose of safe production; this technical solution The defect is obvious, that is, a lot of precious primary energy must be discharged every day. According to the requirement of storage and transportation loss of 1% stipulated by the state, roughly calculated, there will be more than 4 million tons of oil and gas loss in my country every year! And this method still does not feel reassuring. The second method is to spray the oil tank with a high-pressure water source to cool the oil tank; but the defect is that the staff does not know the actual temperature of the filling (because any charged sensor cannot be used), and the Spraying blindly will also waste a lot of water resources
