Description
Technical Field
The utility model belongs to ironmaking fire-fighting equipment field especially relates to a rotary drum belt emergency water installation.
Background
At present, 8 blast furnaces of a saddle steel stock ironmaking main plant adopt a slag flushing process and are divided into a Yinba method, a wheel method and a Jiaheng method according to the process. In general, the water slag flushing process is a granulation, dehydration and external transportation process. Wherein, the rotary drum or the dehydrator is connected with the conveyer belt, and the grain slag is conveyed to a slag yard for outward transportation through the conveyer belt. The red slag enters the rotary drum or the dehydrator due to the reasons of incomplete confirmation of the stokehole and slag flushing operation, system power failure, red slag over Qileng slag and the like, and further causes the initial fire of the conveying belt, even the fire. The existing fire fighting measures and equipment for the grain slag outward conveying belt of the saddle steel are fire extinguishers or fire trucks. Because the temperature of the red slag is high, once the prevention, control and suppression are not timely, the fire disaster is easily caused from the initial fire disaster, even the large fire disaster occurs, the whole belt gallery is burnt, and the production is directly influenced. Because the corrosive gas in the slag flushing belt gallery is more, the slag flushing belt gallery is not suitable for storing fire extinguishers, and the loss of equipment is too large, the fire extinguishers are not configured on the site of the belt gallery. The existing emergency fire fighting mode is that a certain amount of 8kg dry powder fire extinguishers are stored in an electric room and a master control room nearby, and once an initial fire disaster is discovered, in order to extinguish fire timely and effectively, a spray dust suppression vehicle in a factory or a steel-saddle fire fighting emergency center is used for extinguishing fire if necessary.
Disclosure of Invention
The utility model aims at providing a can cool off the red sediment in the shortest time, prevent to ignite the belt, avoid burning the rotary drum belt emergency water installation of losing the belt.
Therefore, the utility model discloses the technical solution who takes does:
the utility model provides a rotary drum belt emergency water installation, includes blast furnace hot-water pond moisturizing pipeline, blast furnace cooling tower moisturizing pipeline and receiving tower moisturizing pipeline, connects emergent water pipe on blast furnace hot-water pond moisturizing pipeline, blast furnace cooling tower moisturizing pipeline and receiving tower moisturizing pipeline respectively, is equipped with the fire hydrant valve on the emergent water pipe, and the fire hydrant valve other end is equipped with the buckle, and the buckle passes through fire hose and connects the squirt.
The supply pressure of the emergency water is more than or equal to 6 kg.
The utility model has the advantages that:
the utility model discloses an use emergency water installation at the rotary drum belt, advance the minimum time behind the rotary drum at red sediment and cool off red sediment, prevent to ignite the belt and cause the fire incident, avoid the accident loss to win favourable operating condition for later stage rotary drum maintenance.
Drawings
Fig. 1 is a schematic structural diagram of a drum belt emergency water device.
In the figure: the system comprises a blast furnace cooling tower water replenishing pipeline 1, a cooling tower emergency water pipe 2, a fire hydrant valve a3, a buckle a4, a fire hydrant hose a5, a water gun a6, a blast furnace hot water pool water replenishing pipeline 7, a hot water emergency water pipe 8, a fire hydrant valve b9, a buckle b10, a fire hydrant hose b11, a water gun b12, a blast furnace receiving tower water replenishing pipeline 13, a receiving tower emergency water pipe 14, a fire hydrant valve c15, a buckle c16, a fire hydrant hose c17, a water gun c18, small flushing slag 19, a cooling tower 20, a water replenishing pipeline 21, a receiving tower 22, a rotary drum 23, a rotary drum belt 24 and a blast furnace 25.
Detailed Description
As can be seen from figure 1, the utility model discloses rotary drum belt emergency water installation is on blast furnace cooling tower moisturizing pipeline 1, blast furnace hot water pond moisturizing pipeline 7 and the basis of blast furnace receiving tower moisturizing pipeline 13 of connecting on the moisturizing pipeline 21 of original blast furnace 25, install the emergent water pipe 2 of cooling tower on blast furnace cooling tower moisturizing pipeline 1, the emergent water pipe 2 of cooling tower is equipped with fire hydrant valve a3, the fire hydrant valve a3 other end has buckle a4, buckle a4 connects squirt a6 through fire hose a 5. A hot water emergency water pipe 8 is installed on a water replenishing pipeline 7 of a blast furnace hot water pool, a fire hydrant valve b9 is installed on the hot water emergency water pipe 8, a buckle b10 is arranged at the other end of the fire hydrant valve b9, and a water gun b12 is connected to the buckle b10 through a fire hose b 11. A receiving tower emergency water pipe 14 is installed on a blast furnace receiving tower water supply pipeline 13, a fire hydrant valve c15 is installed on the receiving tower emergency water pipe 14, a buckle c16 is arranged at the other end of the fire hydrant valve c15, and a water gun c18 is connected to the buckle c16 through a fire hose c 17.
The supply pressure of the emergency water is more than or equal to 6kg, and the pressure can completely meet the use requirement.
Aiming at three states of red slag entering the rotary drum 23, a special emergency plan is established, effective emergency measures are formulated, the accident expansion caused by human errors after the red slag enters the rotary drum 23 is prevented, the accident is controlled in the shortest time, and the loss is reduced.
The first state: before tapping, the plant was not started. And opening a branch valve of the granulation pump at the site, and ensuring that the flushing tank is flushed by using the pressure difference of the cooling tower 20. Strictly forbidding starting the equipment, the emergency water device is used for cooling the rotary drum 23 and the rotary drum belt 24 with water.
And a second state: during tapping, the granulation pump is shut down suddenly (power off). Blocking the gun in front of the furnace, immediately stopping the rotation of the rotary drum 23, keeping the rotary drum belt 24 in the original state, and cooling by using an emergency water device; if black smoke appears on the drum belt 24, the machine is stopped immediately, and emergency water is used for pumping water.
And a third state: and (3) discharging small flushing slag 19 on the same site, if red slag crosses the slag gas and enters the receiving tower 22, further burning the rotary drum belt 24, starting a granulating pump or a circulating pump immediately, intermittently pumping water into the rotary drum 23, and pumping water to cool the rotary drum belt 24 by using an emergency water device.
