Description
Technical Field
The utility model relates to the technical field of reservoir bottom fluidization devices, in particular to an improved reservoir bottom fluidization device.
Background
The fly ash is a pozzolanic mixed material formed by burning coal powder at high temperature. It is a coal-burning power plant which grinds coal to less than 100 micronsThe pulverized coal is sprayed into a hearth by preheated air to be burnt in a suspension state, high-temperature flue gas mixed with a large amount of incombustible substances is generated, and the pulverized coal is captured by a dust collecting device to obtain the pulverized coal. Fly ash is the primary solid waste discharged from coal-fired power plants. If a large amount of fly ash is not treated, dust emission can be generated to pollute the atmosphere; drainage into water causes river silting, and toxic chemicals in the water can also cause harm to human bodies and organisms. The main oxide composition of the fly ash is as follows: siO (SiO) 2 、Al 2 O 3 、FeO、Fe 2 O 3 、CaO、TiO 2 And the like, the chemical composition of the fly ash is similar to that of clay, so the fly ash can be recycled. Because the fly ash has the advantages of fine particles, small density, high specific gravity and the like, the fly ash can be used as a cement raw material or a concrete admixture; meanwhile, the material is an environment-friendly material: the chemical composition is stable, and the building facilities such as the steel bar structure and the like are not toxic, harmless and pollution-free, so the composite material is widely applied to the building material industry and the building industry. However, fly ash is a powdery material which is easy to absorb water, and is generally stored in an ash warehouse and then sent to a using unit in a mode of automobile transportation. When the dry ash is used as a dry ash raw material for beneficial use, the humidity requirement is strict in the storage and transportation processes, so that the dry ash has sufficient fluidity, and the dry ash is convenient to assemble and disassemble and is convenient to blend uniformly in use.
In the prior art, when the normal temperature bin ash bucket or the conical bottom material warehouse is used for discharging, various methods for preventing the material in the bin ash bucket or the conical bottom material warehouse from arching and hardening during discharging to cause unsmooth discharging exist, such as: the bin wall vibrator, the air cannon, the air nozzle, and the like, but each has advantages and disadvantages, and the bin wall vibrator is easy to shake and crack the shell in the use process; the air cannon and the air nozzle blow in point contact, and intermittent discharging is still unsmooth. The method comprises the following steps: the bottom fluidization of the ash warehouse is to provide a certain amount of air through a Roots blower, and the air is sent into a fluidization groove in the ash warehouse for fluidization after being heated. Because the fluidization medium used in the method is air under natural conditions, when the fluidization air enters the interior of the ash bin, the moisture in the air is also brought into the interior of the ash bin along with the fluidization air, so that the moisture content in the interior of the ash bin is increased; once the ash storage time in the ash warehouse is longer, the temperature of the ash is reduced, and the water vapor in the ash is condensed and is absorbed by the dry ash to form hardened ash blocks, so that the ash is difficult to discharge; the interior of the ash bin is a high-dust environment, and meanwhile, due to the fact that a large amount of ash remains, maintenance staff cannot enter the interior of the ash bin for treatment; the hardening of the ash warehouse greatly reduces the ash discharging efficiency and seriously influences the normal production rhythm.
In order to solve the technical defects, an improved bottom fluidization device is needed to solve the technical problems.
