Open type water-sealed valve chamber of dry type blast furnace gas holder

Abstract

The invention provides a technical scheme for an open type water-sealed valve chamber of a dry type blast furnace gas holder. The water-sealed valve chamber comprises a U-shaped gas channel communicated with the blast furnace gas holder, wherein a water collection tank is arranged below the U-shaped gas channel; one end of a delivery pipe is communicated with the bottom of the U-shaped gas channel; the other end of the delivery pipe is communicated with a water drainer which is arranged inside the water collection tank; the water collection tank is also internally provided with a sewage discharging pump; the delivery pipe is provided with a valve. The water-sealed valve chamber is open type, thereby being easy to operate and view; since the water drainer with an automatic stirring function is arranged, water can be drained in time; a CO audible and visual alarm is arranged and can be used for monitoring the open type water-sealed valve chamber area, so that whether gas is leaked can be known at any time; if gas is leaked, an explosion-proof axial flow fan is started to disperse blast gas and lower the gas concentration.

Description

technical field [0001] The invention relates to a water-sealed valve chamber, in particular to an open-type water-sealed valve chamber used for a dry-type blast furnace gas tank. Background technique [0002] In the prior art, the well-known technology is water seal, which refers to a water column with a certain height in the device to prevent the gas in the drainage pipe system from entering the room. In building drainage pipes, water seal refers to the water column at a certain height that is installed under the drain of sanitary appliances to resist the change of pressure difference in the drain pipe and prevent the gas in the drainage pipe system from entering the room. It is usually implemented with a trap . [0003] Usually, the water-sealed valve chamber of dry-type blast furnace gas cabinets is closed, using "U"-shaped water seals, and water drainage is achieved through manual operation.

AI Technical Summary

Problems solved by technology

[0003] Usually, the water-sealed valve chamber of dry-type blast furnace gas tank is closed, adopts "U"-shaped water seal, and realizes drainage through manual operation. When gas leaks, the gas is not easy to diffuse and dilute, causing gas poisoning of operators and endangering life safety.

The gas water seal adopts a "U" type water seal, which requires regular manual drainage, and non-manual contact automatic drainage cannot be realized; the closed gas water seal valve chamber has a limited space, which is an accident-prone place. If the gas leaks, it will cause personal safety accidents , which is the shortcoming of existing technology
