Problems solved by technology

[0008] However, the closed spherical warehouse is in a fully enclosed state, and the ventilation conditions are poor. The heat of the coal pile in the warehouse is easy to accumulate, and the coal pile in the warehouse is prone to spontaneous combustion, producing a large amount of CO and H. 2 Combustible gases such as , hydrocarbon gas and aromatic hydrocarbons will cause very serious safety hazards to coal bunker equipment and personnel safety

Embodiment Construction

[0019] The present invention will be further explained below in conjunction with the drawings:

[0020] Such as figure 1 As shown, in this ball warehouse inerting protection device, the gas storage device 1 is connected to the inflation network pipes at all levels through the pressure reducing device 2. The main valve 12, the first stage inflation pipeline valve 13, and the second stage inflation pipeline valve 14 , The third-stage inflation pipeline valve 15 controls the on-off of all stages of inflation network management.

[0021] Such as figure 2 As shown, the first-stage inflatable embedded pipe 3 of the ball silo inerting protection device is arranged at all the coal outlets at the bottom of the ball silo. During inerting protection, the main valve 12 and valve 13 are opened to inert the ball silo bottom. The gaseous carbon dioxide suppresses the hot air pressure effect caused by the spontaneous combustion temperature rise of the coal pile in the ball bin, and achieves the p...

Abstract

The invention discloses an inactive protect device for a ball-shaped bunker. The inactive protect device is used for conducting inactive protection on large-sized ball-shaped coal storage bunkers of thermal power stations and the like. According to the inactive protect device, a gas storage device is connected with multiple stages of gas filling pipelines through a decompression device, and can adjust the pressure of inert gas filling, and a main valve is arranged on a main pipeline behind the decompression device, and is used for controlling the connection and disconnection of the main pipeline; the inactive protect device is composed of the gas storage device, the decompression device, embedded pipes arranged at the coal outlet of the bottom and the wall of the ball-shaped bunker, a gas filling device arranged on the upper portion of the ball-shaped bunker, and the multiple stages of gas filling pipelines. Firstly gas filling is conducted on the bottom and the upper portion of the ball-shaped bunker, and then the effect of ''isolation-restraining'' is achieved by conducting gas filling inside a coal dump, and finally the inactive protection of a whole coal dump in the ball-shaped bunker is formed.

Description

Technical field [0001] The invention relates to an inerting protection device for a ball bin. It is suitable for inerting protection of spherical coal storage bins in coal storage places such as thermal power plants, coal mines, and coal washing plants. Background technique [0002] The coal storage yard is an important place for coal storage and coal supply such as coal-fired power plants, coal mines, and coal washing plants, which is related to the safe and stable production of power plants. With the continuous expansion of domestic coal-fired unit capacity and construction scale, increasing attention to environmental protection and increasingly valuable land resources, a new coal storage method-closed spherical coal bunker has begun to be applied at home and abroad. Compared with other coal yards, the spherical coal bunker uses a large-diameter reinforced concrete thin-shell structure. Although the cost is higher, it has the following advantages: [0003] (1) The occupied area...
