Problems solved by technology

[0011] It can be seen from the above that according to the current domestic regulations, the calculation of storage tank spacing mainly considers the diameter parameters of storage tanks. Although this calculation is simple, it does not take into account the actual conditions of storage tanks in the tank farm. Different storage tanks store different materials, and the characteristics of fires also vary It is not the same, and it does not take into account the daily protection facilities of the storage tank, so the algorithm has certain defects in practical application

Embodiment Construction

[0066] The present invention will be described in detail in conjunction with accompanying drawing now. This figure is a simplified schematic diagram only illustrating the basic structure of the present invention in a schematic manner, so it only shows the components relevant to the present invention.

[0067] Such as figure 1 As shown, a method for calculating the fire separation distance of above-ground storage tanks of the present invention includes the following steps:

[0068] S1: Determine the basic information of the storage tank, such as the medium, diameter, height, material, etc. 3 The methanol storage tank is the research object, its diameter is 4.4m, the height is 7.5m, and the fire distance from the surrounding storage tanks is 3.3m; and the position of one of the tanks is known;

[0069] S2: Assume that the fire in the storage tank is a full-surface fire, and the liquid level in the burning tank is the same as the tank height. According to the actual situation ...

Abstract

The invention provides a method for calculating the fire protection distance of an aboveground storage tank, belonging to the technical field of building fire protection. According to the protection water requirement of heat radiation intensity in case of fire, the optimum distance between adjacent storage tanks is obtained by calculating the heat radiation energy of fire storage tanks, the absorbed value of radiation energy received by adjacent storage tanks and water counteracted by their water spraying systems. This method provides a new quantitative calculation method of tank spacing whichis more practical, and makes the storage area of the tank safer. Moreover, the separation distance between adjacent storage tanks can be adjusted by calculating the application rate of water, which can also save the area of storage tank area, facilitate the laying and installation of fire control pipe network and the construction of public facilities.

Description

technical field [0001] The invention relates to the technical field of building fire protection, in particular to a method for calculating the fire separation distance of above-ground storage tanks. Background technique [0002] Storage tanks in the chemical industry contain a large amount of combustible substances, and the storage tanks have a large capacity. From the experience and lessons of previous accidents, it can be seen that once a fire occurs in a storage tank containing flammable liquid, it is very difficult to control and extinguish the fire. Due to the high burning degree and intensity of the fire, the possibility of causing damage to nearby equipment and causing serious impacts on the environment is also high. [0003] According to the "Code for Fire Protection of Building Design" GB50016-2014, at present, the distance between the above-ground storage tanks of most professional oil depots and industrial enterprise oil depots in China is one D (D is the diamete...
