Embodiment 1

[0021] figure 1 Shown is the storage tank area integrated breathing valve device according to the present invention, including four gasoline storage tanks 1, the volume is 2000m 3 , the diameter of the gas connection pipeline 2 of the storage tank is DN15, the buffer 3 is a cylindrical container with a diameter of DN800, and a length of 2m; the number of airbags 4 is 2, installed at both ends of the buffer 3, and the most bulging or inhaling The longest length is 800mm. The storage tank 1 is connected to the inlet of the buffer 3 through the gas connection pipeline 2 of the storage tank. The buffer 3 is provided with an air bag 4, and the outlet of the buffer 3 is connected to the breathing valve 5. The breathing valve 5 uses a spring limit valve plate, which is controlled by a positive Negative pressure determines whether to breathe or breathe, and consists of two parts: a pressure valve and a vacuum valve. The outlet pipelines of the four gasoline storage tanks are merged ...

Abstract

The invention relates to a storage tank area integrated breathing apparatus. The problem that breather valves of multiple storage tanks stored with the same media in the prior art are excessive, small in buffering capacity and large in waste gas emission load is mainly solved. The storage tank area integrated breathing apparatus comprises at least two storage tanks 1, at least one storage tank gas connecting pipe 2, a buffer 3, at least one air bag 4 and a breather valve 5. The storage tanks 1 are connected with an inlet of the buffer 3 through the storage tank gas connecting pipe 2, the air bag 4 is arranged on the buffer 3, and an outlet of the buffer 3 is connected with the breather valve 5. The problem is well solved by adopting the technical scheme, and the storage tank area integrated breathing apparatus can be used for various tank areas.

Description

technical field [0001] The invention relates to an integrated breathing device for a storage tank area. technical background [0002] Storage tanks are one of the common equipment in petroleum, petrochemical, chemical and coal chemical industries, used to store liquid materials. Storage tanks generally require the installation of breathing valves. The storage tank breathing valve is an important accessory to protect the safety of the storage tank. The breathing valve is a safe and energy-saving product that maintains the air pressure balance of the storage tank and reduces the volatilization of the medium. The breathing valve makes full use of the pressure bearing capacity of the storage tank itself to reduce the discharge of the medium. The principle is to use The weight of the positive and negative pressure valve disc is used to control the positive exhaust pressure and negative suction pressure of the storage tank. When the pressure of the medium in the tank is within t...
