Description
Technical Field
The utility model relates to a hot stuffy pond technical field of converter slag especially relates to a converter slag hot stuffy pond gas emission system.
Background
The hot disintegration of the steel slag is a widely applied converter steel slag treatment process. As shown in FIG. 1, the hot stuffy box is the main process facility in the process, and other equipment matched with the hot stuffy box for hot stuffy operation also comprises a hot stuffy cover, a movable hood van and an air 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. The movable cover vehicle is provided with an exhaust pipe, the exhaust pipe is connected with an air extractor, and gas in the movable cover vehicle is extracted through the air extractor.
The existing converter steel slag hot stuffy tank gas discharge system has the following defects: 1. the air extraction device conventionally extracts air by an air extraction fan, and a plurality of hot stuffy pools are usually arranged in a factory building and are correspondingly provided with a plurality of mobile cover cars. When a plurality of hot stuffy ponds are produced simultaneously, the air extractor is often difficult to extract the gas in a plurality of mobile cover cars in time, so that the gas escapes from the periphery of the mobile cover cars, the field operation environment is affected, and potential safety hazards exist. 2. In order to be able to feed material into the hot well and to transport the material after birth, the mobile gondola must obviously not be stationary but rather be mobile. The existing movable cover vehicle is provided with an exhaust pipe, the exhaust pipe moves along with the movable cover vehicle, and the size of the exhaust pipe is large, so that the movable cover vehicle is inconvenient to move.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: provides a converter steel slag hot stuffy tank gas discharge system with stronger exhaust capacity.
The technical scheme adopted for solving the problems is as follows: converter slag hot stuffy pool gas emission system is including removing cover car, blast pipe and air exhaust device, and air exhaust device is including setting up in the aspirating hole of underground and the main air exhaust fan that is located the aspirating hole outer end, and the blast pipe is connected with removing the cover car and corresponds with the inner position of aspirating hole, is provided with time air exhaust fan on the blast pipe.
Further, the method comprises the following steps: the exhaust pipe is fixed on the ground and is detachably connected with the movable cover vehicle.
Further, the method comprises the following steps: the exhaust pipe is connected with the movable cover vehicle through a flange.
Further, the method comprises the following steps: the exhaust pipe includes a bellows section adjacent to the flange.
The utility model has the advantages that: 1. set up the inferior air exhaust fan on the blast pipe, as the replenishment of main air exhauster, remedy the not enough problem of a plurality of hot stuffy ponds during operation owner air exhaust fan suction capacity simultaneously, can realize removing the gas in the cover car in time discharging, avoid gaseous from removing the peripheral loss of cover car.
2. If direct increase main air exhauster power, then can lead to main air exhauster power waste and energy extravagant when the hot vexed pond quantity of work is less, the utility model discloses when the hot vexed pond quantity of work is less, the energy consumption is lower relatively.
3. Further fix the blast pipe on subaerial, the blast pipe can be dismantled with removing the cover car and be connected. The movable cover vehicle is not provided with the exhaust pipe, and the exhaust pipe does not move together with the movable cover vehicle, so that the weight of the movable cover vehicle is obviously reduced, the volume is obviously reduced, and the movable cover vehicle is more convenient to move. The exhaust pipe is arranged beside the hot stuffy tank, and does not hinder the feeding of materials into the hot stuffy tank and the transportation of the materials after birth.
Drawings
FIG. 1 is a schematic view of a converter slag hot stuffy tank gas discharge system;
FIG. 2 is a schematic view of the mobile cowling cart and exhaust duct;
labeled as: the hot stuffy pool comprises a hot stuffy pool 1, a hot stuffy cover 2, a pressure relief opening 3, a movable hood vehicle 4, an exhaust pipe 5, a secondary air extractor 51, a corrugated pipe section 52, an air extractor 6, an air extraction hole 61 and a main air extractor 62.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1 and 2: converter slag hot stuffy pool gas emission system is including removing cover car 4, blast pipe 5 and air exhaust device 6, and air exhaust device 6 is including setting up at underground aspirating hole 61 and the main air exhaust fan 62 that is located the aspirating hole 61 outer end, and blast pipe 5 is connected with removing cover car 4 and is corresponding with the inner position of aspirating hole 61, is provided with time air exhaust fan 51 on the blast pipe 5.
Set up secondary exhaust fan 51 on blast pipe 5, as the supplementary of main air exhauster 62, compensate the not enough problem of main exhaust fan 62 suction capacity when a plurality of hot stuffy ponds 1 during simultaneous operation, can realize removing the gas in the cover car 4 and in time discharge, avoid gaseous from removing the peripheral loss of cover car 4. The power of the main exhaust fan 62 is relatively directly increased, and the energy consumption is relatively low when the number of the hot stuffy ponds 1 in work is less.
In order to facilitate the movement of the mobile vehicle, it is preferred that the exhaust pipe 5 is fixed on the ground, and the exhaust pipe 5 is detachably connected to the mobile vehicle 4. Therefore, the weight of the movable cover vehicle 4 is obviously reduced, the volume is obviously reduced, and the movement is simpler and more convenient. The exhaust pipe 5 is arranged beside the hot stuffy tank 1, and does not prevent the material from being added into the hot stuffy tank 1 and the material after birth.
The exhaust pipe 5 is preferably connected to the mobile cowling vehicle 4 by a conventional flange connection.
Further in accordance with the present invention, it is preferred that the exhaust pipe 5 includes a bellows section 52 adjacent the flange. Bellows section 52 can be extended and swung to facilitate the alignment of the flanges of mobile cowling cart 4 and exhaust pipe 5, and to avoid interference in the process of moving cowling cart 4 to align with exhaust pipe 5. In addition, because the gas temperature is high, the exhaust pipe 5 and the mobile trolley 4 are inevitably deformed after being used, and the corrugated pipe section 52 can ensure that flanges of the two can still be aligned when the two are deformed.
