Abstract

A dome roof tank provided with a fire fighting facility, especially a dome roof tank provided with a built-in fire fighting apparatus, is provided. The dome roof tank includes a tank body. A transportation pipe is disposed on the bottom of the tank body, is arranged underground and is provided with a pressure valve. A pressure detector is arranged in the tank body. A fire extinguishing agent transporting pipe, which is arranged underground, is also disposed on the bottom of the tank body and is used for transporting a fire extinguishing agent into the tank body according to indication by the pressure detector; and the transportation pipe is used for sending the substance stored in the tank body to exterior according to indication by the pressure detector. Compared with the prior art, if fire hazard and explosion occur in the tank body, the substance stored in the tank body can be moved out and the fire extinguishing agent is ejected into the tank body timely, so that secondary explosion in the tank body is prevented and flame in the tank body is inhibited. By means of the structure, the fire hazard in the tank body can be extinguished or inhibited so as to gain time for external rescue.

Description

technical field [0001] The invention relates to a fire-fighting device for a vault tank, in particular to a built-in fire-fighting device. Background technique [0002] Vault storage tank refers to a steel container with a spherical crown and a cylindrical tank body. Vault storage tanks are easy to manufacture and low in cost, so they are widely used in many industries at home and abroad, and the most commonly used volume is 1000-10000m 3 At present, the maximum volume of domestic vault storage tanks has reached 30,000m 3 . Vaulted tanks often store toxic chemicals or flammable petroleum products, so the protection of vaulted tanks is very important. In recent years, several major production safety accidents in our country were caused by defective storage media or insufficient protection. For oil storage vault tanks, there are fire-fighting facilities on the tank, but according to the actual use, these fire-fighting facilities outside the tank do not play much role, oft...
