Different pressure gas pipe network intercommunication device

Abstract

The invention discloses a different-pressure gas pipe network intercommunication device. The different-pressure gas pipe network intercommunication device comprises a liquid seal pressure control box. The liquid seal pressure control box is internally provided with a middle partition plate which divides the liquid seal pressure control box into a left chamber and a right chamber. The left chamber and the right chamber are both filled with water. The top of the left chamber is provided with a left gas port and a left gas pipe of which the lower port is inserted below the liquid level in the left chamber. The left gas port communicates with a high-pressure gas pipe network. The upper port of the left gas pipe communicates with a low-pressure gas pipe network. The top of the right chamber is provided with a right gas port and a right gas pipe of which the lower port can be inserted below the liquid level in the right chamber. The right gas port communicates with the low-pressure gas pipe network. The upper port of the right gas pipe communicates with the high-pressure gas pipe network. A left water replenishing pipe is arranged on the upper portion of the left chamber. A left drainage pipe is arranged at the bottom of the left chamber. A right water replenishing pipe is arranged on the upper portion of the right chamber. A right drainage pipe is arranged at the bottom of the right chamber. According to the different-pressure gas pipe network intercommunication device, the pressure of the high-pressure gas pipe network can be adjusted.

Description

technical field [0001] The invention relates to the field of different-pressure pipe network intercommunication equipment, in particular to a device for intercommunicating high-pressure gas pipe networks and low-pressure gas pipe networks. Background technique [0002] The different-pressure gas pipeline network is a high-pressure gas pipeline network and a low-pressure gas pipeline network. In order to enable the high-pressure gas pipeline network to transport gas to the low-pressure gas pipeline network, the high-pressure gas pipeline network and the low-pressure gas pipeline network are usually directly connected through pipelines. , for example: in order to enable the blast furnace gas pipeline network belonging to the high-pressure gas pipeline network to transport blast furnace gas to the gas cabinet belonging to the low-pressure gas pipeline network, the blast furnace gas pipeline network and the gas cabinet are usually directly connected through pipelines; this direct...

[0002] The different-pressure gas pipeline network is a high-pressure gas pipeline network and a low-pressure gas pipeline network. In order to enable the high-pressure gas pipeline network to transport gas to the low-pressure gas pipeline network, the high-pressure gas pipeline network and the low-pressure gas pipeline network are usually directly connected through pipelines. , for example: in order to enable the blast furnace gas pipeline network belonging to the high-pressure gas pipeline network to transport blast furnace gas to the gas cabinet belonging to the low-pressure gas pipeline network, the blast furnace gas pipeline network and the gas cabinet are usually directly connected through pipelines; this direct connection method The disadvantage is: because the pressure of the gas in the blast furnace gas pipe network needs to be maintained within the specified range, and because the pressure of the gas in the blast furnace gas pipe network is greater than the pressure of the gas in the gas cabinet, the blast furnace gas pipe network will always deliver blast furnace gas to the gas cabinet , which will cause the gas pressure in the blast furnace gas pipe network to be too low, which is not conducive to the normal operation of the blast furnace gas pipe network
