Oil storage tank anti-deflagration device

Abstract

The invention discloses an anti-explosion device for an oil storage tank in the technical field of an anti-explosion device, comprising a large oil storage tank and a small oil storage tank, the small oil storage tank is arranged inside the large oil storage tank, and the large oil storage tank The inner wall is provided with an oil and gas concentration alarm, the inside of the large oil storage tank is provided with a fabric layer, and the outer wall of the large oil storage tank is provided with an audible and visual alarm. The beryllium bronze layer of the present invention is Although the temperature of the surface or some detached particles has increased, they cannot undergo violent oxidation reactions with other combustible gases, and cannot form an ignition source to prevent deflagration. The 3D hollow fabric layer has good heat insulation and sound insulation effects, and It has the characteristics of light material, high strength, corrosion resistance, and good damage tolerance. The low-temperature natural gas is quickly heated to room temperature through a water bath heat exchange tank, and is pressurized by a gas compressor to be transported to a high-pressure buffer collection tank for collection.

Description

technical field [0001] The invention relates to the technical field of anti-explosion devices, in particular to an anti-explosion device for an oil storage tank. Background technique [0002] When the oil storage tank is in operation, it is inevitable to leave an oil film on the tank wall. There is no wax scraping mechanism or the storage tank with poor wax scraping effect even has a large amount of flaky crude oil attached to the tank wall, which falls into one, Between the secondary seals, especially in high temperature seasons, a large amount of light components in crude oil volatilize, resulting in extremely high concentrations of combustible gases between the primary and secondary seals of the oil storage tank. Therefore, due to the limitations of the structure, operation mode and storage medium of the oil storage tank, although the oil storage tank has undergone safety hazard rectification (the sealing method is changed from a mechanical seal to a soft seal, and the el...

AI Technical Summary

Problems solved by technology

Therefore, due to the limitations of the structure, operation mode and storage medium of the oil storage tank, although the oil storage tank has undergone safety hazard rectification (the sealing method is changed from a mechanical seal to a soft seal, and the electrostatic lead-out line is thickened, etc.), the oil storage tank has a , There is still a closed combustible gas space in the secondary seal, and there is still a risk of deflagration when exposed to the ignition point
