The hot disintegration of the steel slag is a widely applied converter steel slag treatment process. As shown in fig. 1, in the process, the hot stuffer tank is the main process facility, and other equipment which is matched with the hot stuffer tank for hot stuffer operation also comprises a hot stuffer cover, a movable hood van and an exhaust device. The working principle is as follows: when the steel slag is hot and stuffy, the hot stuffy cover is covered above the hot stuffy pool, on one hand, the hot stuffy cover is connected with a water supply pipe, a spray head in the hot stuffy cover uniformly pumps water to the steel slag in the hot stuffy pool, on the other hand, the hot stuffy cover can keep certain pressure in the hot stuffy pool in sealing, and steam can be in full contact reaction with the steel slag better. After the steam contacts and reacts with the steel slag in the hot stuffy tank, combustible gas such as hydrogen, carbon monoxide and the like can be generated and gathered to a certain concentration, which is easy to cause explosion. In order to ensure safety and prevent explosion caused by over-pressure or other reasons, a pressure release valve is arranged on the hot stuffy cover, when the pressure is over-pressure, the pressure release valve is opened, steam in the hot stuffy pool is discharged, and gas is gathered in the mobile cover vehicle. And the gas in the movable cover vehicle is exhausted through an exhaust device.
The main role of the mobile cowling vehicle is to temporarily store the gas discharged by the pressure relief valve and to protect it in the event of an explosion. The size of the mobile cover vehicle is large, the mobile cover vehicle must be transferred to the upper part of the hot stuffy tank through a crane, a track and other modes before the cover of the hot stuffy tank starts hot stuffy, and the operation is complex; meanwhile, the internal space of the movable cover vehicle is larger, the load of the exhaust device is increased, and the air draft efficiency is reduced; the lifting space of the slag pot and the like is also influenced above the hot stuffy pool by the movable cover car, so that the lifting height of the slag pot is higher, and the safety risk is higher; the space in the mobile covered vehicle increases the possibility that the combustible gas is gathered to reach the explosion limit, and the safety risk is higher. In addition, because the height of the mobile cover vehicle is high, the exhaust device is correspondingly arranged to be very high, and the arrangement difficulty of the exhaust device is higher.
With the progress of technologies, the probability of explosion of the hot stuffy pool is very low at present, the necessity of moving the cover vehicle is reduced, and the mode of gas discharge of the hot stuffy pool has improved space and necessity.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the direct-exhaust hot stuffy pool exhaust system is simple in structure.
The technical scheme adopted for solving the problems is as follows: the direct-discharging hot stuffy pool exhaust system comprises a hot stuffy cover and an exhaust device, wherein the hot stuffy cover is provided with a pressure relief opening, a pressure relief valve is arranged on the pressure relief opening, and the exhaust device can lead out gas discharged by the pressure relief valve; the device also comprises an exhaust pipe; the exhaust device comprises a connecting cover, an air draft device and an air draft hole arranged underground, the connecting cover and the air draft device are respectively arranged at two ends of the air draft hole, and an air draft interface is arranged on the connecting cover; the quantity of blast pipe and convulsions interface is the same with the quantity of hot stifle, and a blast pipe is connected with the pressure release mouth of a hot stifle and can dismantle with an convulsions interface and be connected.
Further, the method comprises the following steps: the both ends of blast pipe all are provided with the joint, and the blast pipe passes through joint and pressure release mouth and convulsions interface threaded connection.
Further, the method comprises the following steps: the exhaust device comprises a sealing cover, the sealing cover and the air draft interface are arranged in a one-to-one correspondence mode, and the sealing cover is connected with the connecting cover through a flexible rope; when the exhaust pipe is separated from the air draft interface, the sealing cover can be connected with the air draft interface to seal the air draft interface.
The utility model has the advantages that: 1. the utility model discloses saved prior art's removal cover car, the relief valve combustion gas is direct discharges to the factory building outside through blast pipe and exhaust apparatus. The structure of the steel slag hot stuffy tank gas discharge system is greatly simplified while gas can be discharged as in the prior art, and the power required by an exhaust device is reduced; because the movable cover vehicle in the prior art is saved, the height of the exhaust pipe is greatly reduced, the exhaust device is arranged at a low position, and the exhaust device is convenient to arrange; the operation of cover car removal handling has been reduced, reduces the maintenance of equipment cost of overhaul simultaneously, increases the site space, improves convulsions efficiency, has avoided combustible gas to gather outside the hot stuffy pond simultaneously, reduces the explosion risk.
2. The quantity of blast pipe and air extraction interface is the same with the quantity of hot stifle lid, has a plurality of hot stifle ponds in a factory building usually, also has a plurality of hot stifle lids. The gas in each hot pool can be discharged through the same exhaust device, thereby simplifying the structure of the utility model.
