Description
Technical Field
The utility model relates to a dust humidifier for a blast furnace dust removal system. Belongs to the technical field of dust removal.
Background
The smoke dust mainly generated by the casting house comprises the smoke dust generated by a tapping hole, a skimmer, a molten iron runner, a slag discharging runner, a swinging launder and the like during normal casting. The treatment of the smoke dust in the cast house is of great importance, if the smoke dust is not effectively treated, the smoke dust not only pollutes the operating environment of the cast house and harms the health of operating workers (especially, the free SiO2 in the smoke dust can cause great harm to the respiratory system of a human body, and the smoke dust in the cast house contains about 3.67 percent of free SiO 2), but also pollutes the atmospheric environment of a blast furnace area.
The blast furnace front dust removing system is a negative pressure system consisting of a blast furnace taphole top suction cover, a side suction cover, a main iron groove cover, an iron groove cover, a slag groove cover, a residual iron groove cover, a swinging chute cover plate, an anti-dew low-resistance pulse bag type dust remover, a fan station and speed adjusting device, a pipe network system, an exhaust funnel, an ash discharging system, a pulse air source processing system, an electric and automatic control system, an illumination system, a support, a steel structure and a civil engineering concrete foundation.
Under the action of an induced draft fan, when the blast furnace is cast, high-temperature flue gas in a cast house enters a trapping cover together with mixed cold air under the action of a thermal lift force and a negative pressure field at the mouth of the trapping cover, enters a dust remover through a pipe network for purification, and enters an exhaust funnel through the induced draft fan to be directly discharged into the atmosphere; the dust enters the dust storage bin, enters the humidifier for humidification under the control of the dust discharge valve, and is finally carried away by the dust discharge vehicle.
Most of the existing dust humidifiers are double-shaft stirring shafts, water is sprayed through nozzles, dust and water are stirred into wet materials with 20-30% of water through the stirring of the stirring shafts, and secondary dust pollution can be reduced when the wet materials are subsequently transported away through a dust unloading vehicle.
The Chinese utility model patent (application number: 201820569397.X) discloses a dust humidifier, wherein a stirring shaft is connected with a spray pipe through gear transmission, and when the stirring shaft stirs materials, the spray pipe synchronously rotates, so that dust is uniformly humidified, and the phenomenon of dust stagnation in the stirring process is reduced.
The above patent has the following problems: 1. the spray pipe is positioned below the feed inlet, and when the humidifier feeds materials, part of dust falls on the spray pipe, or the spray pipe prevents the dust from being fed smoothly; 2. the drive gear at the outer end of the stirring shaft is connected with the drive gear of the shower pipe through an intermediate gear, so that the rotation directions of the stirring shaft and the shower pipe are the same (both anticlockwise and both clockwise), while the stirring shafts of the above patent are double shafts, so that the rotation direction of one stirring shaft is the same as that of the shower pipe, and the rotation direction of the other stirring shaft is opposite to that of the shower pipe (see fig. 4), and as can be seen from fig. 4, inertia caused by rotation of the shower pipe enables water flow to have a certain direction, and particularly when the shower pipe rotates faster, the direction of the water flow is more obvious, so that one result is that: the rotating spraying pipe cannot uniformly humidify the dust, but aggravates the problem that the local water amount of the dust is too large (the water amount obtained by one stirring shaft is too large); 3. the humidified dust directly enters the dust discharging vehicle through the discharge hole, and the water-containing dust stirred by the stirring shaft is not formed and still has the possibility of generating secondary dust; 4. dust is directly fed from the feeding hole, and the feeding is uneven, so that the material blockage is directly caused.
