Description
Technical field
The invention belongs to fuel gas transmission technical fields, more particularly to a kind of device for gas pipeline water seal.
Background technique
Blast furnace generates a large amount of blast furnace gas in smelting process, after dust separation, top pressure power generation, blast furnace purified gas edge
Pipeline flows into gas main and hot blast stove system, when blast furnace maintenance, usually in blast furnace gas processing system and general pipeline coal gas
Water seal is carried out using U-tube between system, quickly and effectively by two partial partitions, to carry out upkeep operation.But this water seal
Technology has the following deficiencies: since blast furnace gas pipeline is relatively large in diameter, and is filled the water using common water supply line to U-shaped gas pipe, note
The water time is long, and there are the security risks that water seal is easily punctured by blast furnace gas.
Summary of the invention
To solve the above problems, the present invention proposes a kind of device for gas pipeline water seal, the device knot
Structure is simple, easy to use, can quickly and effectively block the conveying of combustion gas, and can eliminate the safety that water seal is punctured by high-pressure gas
Hidden danger.
To achieve the goals above, the present invention uses following scheme, comprising:
Water tank；
Positioned at the overflow pipe of the left side joining water box of water tank；
Positioned at the water supply pipe of the right side joining water box of water tank, which concatenates moisturizing control valve；
Positioned at the steam pipe of the top joining water box of water tank, which concatenates steam control valve 6；
Water drainage U-shape pipe, draining control valve, row are concatenated in the drainpipe of the bottom joining water box of water tank, the drainpipe
The other end of water pipe is connected to combustion gas U-tube；
It is connected to the top of water tank and protrudes into the water-level gauge in water tank, which is electrically connected controller.
Height of the water drainage U-shape pipe nozzle apart from bottom is 4 meters.
The drainpipe is connected to combustion gas U-tube, and height of the connectivity points apart from combustion gas U-tube bottom is greater than 4 meters.
The distance from bottom drainpipe of the water tank and the height of combustion gas U-tube connectivity points are greater than 3 meters.
The moisturizing control valve is solenoid valve.
The configuration of the present invention is simple, it is easy to use, the conveying of combustion gas can be quickly and effectively blocked, and it is high to eliminate water seal
The security risk of compression ignition gas breakdown.
Detailed description of the invention
Fig. 1 is schematic view of the front view of the present invention.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing, so that those skilled in the art can be more clear
The understanding of Chu, as shown in Figure 1, the present invention includes:
Water tank 1；
Positioned at the overflow pipe 2 of the left side joining water box of water tank；
Positioned at the water supply pipe 3 of the right side joining water box of water tank, which concatenates moisturizing control valve 4；
Positioned at the steam pipe 5 of the top joining water box of water tank, which concatenates steam control valve 6；
Water drainage U-shape pipe 8, draining control valve 9 are concatenated in the drainpipe 7 of the bottom joining water box of water tank, the drainpipe,
The other end of drainpipe is connected to combustion gas U-tube 10；
It is connected to the top of water tank and protrudes into the water-level gauge 11 in water tank, which is electrically connected controller.
As the preferred embodiment of the present invention, height of 8 nozzle of water drainage U-shape pipe apart from bottom is 4 meters.
As the preferred embodiment of the present invention, the drainpipe is connected to combustion gas U-tube 10, and connectivity points are apart from combustion gas U-shaped
The height of 10 bottom of pipe is greater than 4 meters.
As the preferred embodiment of the present invention, distance from bottom drainpipe and 10 connectivity points of combustion gas U-tube of the water tank 1
Height is greater than 3 meters.
As the preferred embodiment of the present invention, the moisturizing control valve 4 is solenoid valve.
When blast furnace maintenance, draining control valve 9, the fast water injection into combustion gas U-tube 10, when in combustion gas U-tube 10 are opened
Water level when reaching setting height, close draining control valve 9, gas pipeline 12 is quickly and effectively blocked, the water in water tank 1
Position decline to a certain extent when, the contact trigger controller of water-level gauge 11, the controller starting automatic water supplement of moisturizing control valve 4 is to setting
Fixed water level, it is that the water freezing in winter water tank, water drainage U-shape pipe 8 can effectively prevent firing in order to prevent that steam is passed through in water tank 1
Has channeling, which enters water tank, leads to the accident of gas leakage.
The configuration of the present invention is simple, it is easy to use, the conveying of combustion gas can be quickly and effectively blocked, and it is high to eliminate water seal
The security risk of compression ignition gas breakdown.
