To achieve the above object, the utility model is achieved through the following technical solutions:
A kind of blast furnace wet process deashing dust-extraction unit, including shell, ash inlet, top spray pipe, middle part spray tube, bottom spray
Shower pipe divides grey body, wet grey collecting tank, and case top is equipped with ash inlet, be from top to bottom connected in turn in shell top spray pipe,
Middle part spray tube, bottom spray pipe are equipped between top spray pipe, middle part spray tube and divide grey body, are equipped with below the spray tube of middle part
Wet ash collecting tank, top spray pipe, middle part spray tube, bottom spray pipe are respectively connected with more than two water inlet pipes, described into ash
The flange that can be connect with blast furnace connecting tube is equipped at the top of mouthful；The shell is radially hinged with several cleaning doors；
The top spray pipe, middle part spray tube, bottom spray Guan Shangjun radial equipartition have spiral nozzle, top spray
It is placed with spiral nozzle on the inside of pipe and bottom spray pipe, is placed with spiral nozzle on the outside of the spray tube of middle part；
The cleaning door includes hinge, door body, buckle, extends channel, sealing ring, and sealing ring, card are fixed in door body
Button extends channel and case weld, and extension channel is hinged by hinge with door body, extends channel and is connected by a snap with door body,
Door body and extension channel pass through sealing ring and seal.
The top spray pipe, middle part spray tube, bottom spray pipe are the different cyclic structure of diameter, middle part spray tube
Diameter is minimum.
Check valve is connected on the water inlet pipe.
Compared with prior art, the utility model has the beneficial effects that
Blast furnace wet process deashing dust-extraction unit weight of equipment is light, compact-sized small in size, and occupied area is small, easy to operate, dimension
Convenience, at low cost, long service life are repaired, site operation personnel is reduced to 2 people by original nearly ten people, collects three sections of cleanings in one
Body, dust suppression efficiency are up to 99% or more, good dedusting effect.Original all dynamical systems have been abolished, water pipeline is only remained,
Site space environment is set to become larger.Shower water staggeredly carries out, and prevents reentrainment of dust.The present apparatus uses flanged joint, avoids junction
Fugitive dust.Spray tube uses two water inlets, and enhancing spray hydraulic pressure improves spraying effect.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is the perspective view of the utility model.
In figure: spray tube 4- bottom spray pipe 5- shell 6- cleaning door in the middle part of 1- top spray pipe 2- ash inlet 3-
7- water inlet pipe 8- wet ash collecting tank 9- divide grey body 10- muscle bar.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings of the specification, it should be noted that the utility model
Implement embodiment not limited to the following.
See Fig. 1, Fig. 2, blast furnace wet process deashing dust-extraction unit, including shell 5, ash inlet 2, top spray pipe 1, middle part spray
Pipe 3, bottom spray pipe 4 divide grey body 9, wet grey collecting tank 8, are equipped with ash inlet 2 at the top of shell 5, in shell 5 from top to bottom successively
It is connected with top spray pipe 1, middle part spray tube 3, bottom spray pipe 4, a point ash is equipped between top spray pipe 1, middle part spray tube 3
Body 9 is equipped with wet grey collecting tank 8 below middle part spray tube 3；Divide grey body 9 fixed by muscle bar 10 and shell 5, wet ash collecting tank 8 is consolidated
It is scheduled in shell 5.Top spray pipe 1, middle part spray tube 3, bottom spray pipe 4 are respectively connected with more than two water inlet pipes 7, increase
The pressure and unit inflow of water inlet, avoid reentrainment of dust.It is connected with check valve on water inlet pipe 7, reflux when preventing hydraulic pressure low.
The flange that being equipped at the top of ash inlet 2 can connect with blast furnace connecting tube prevents the present apparatus and blast furnace to improve leakproofness
Junction fugitive dust.
Cleaning door 6 includes hinge, door body, buckle, extends channel, sealing ring, and sealing ring, buckle are fixed in door body, is prolonged
It stretches channel and shell 5 welds, extension channel is hinged by hinge with door body, and extend channel and is connected by a snap with door body, door body
It is sealed with channel is extended by sealing ring.Plug-type cleaning door 6 is set on existing part dust-extraction unit, is filled for a long time using dedusting
It postpones dust humidity to be deposited in slideway, will lead to the case where cleaning door 6 can not be opened, therefore the radial hinge of shell 5 of the present apparatus
It is connected to 4-6 cleaning door 6, cleaning door 6 is equipped with sealing ring, is enhanced its sealing using round hinge-type pressing door, cleaning door 6
Property, cleaning door 6 is opened in the case where facilitating dust to block up door.
Top spray pipe 1, middle part spray tube 3, radial equipartition has spiral nozzle, top spray pipe 1 on bottom spray pipe 4
It is placed with spiral nozzle with the inside of bottom spray pipe 4, the outside of middle part spray tube 3 is placed with spiral nozzle；Spiral nozzle exists
Guarantee that spray obstruction can be reduced under the premise of smooth runner, so that shower water is reached maximum stream flow on pipeline, avoid gas ash
Dirt blocks spiral nozzle.Top spray pipe 1, middle part spray tube 3, bottom spray pipe 4 are the different cyclic structure of diameter, middle part spray
3 diameter of shower pipe is minimum, can make shower water interlaced arrangement in shell 5, improve the spray area of dust, avoid reentrainment of dust.
The present apparatus is through flanged joint in blast furnace connecting tube, work, and blast furnace coal ash enters by ash inlet 2 first
In present apparatus body, the mist-like small water fog particle that shower water is sprayed by spiral nozzle carries out cleaning humidification dedusting, entrance
Coal ash is fully absorbed in the spray water sprayed by spiral nozzle by coal ash, so that the coal ash of discharge is guaranteed temperature and humidity, is prevented
Reentrainment of dust.Dust in coal gas makes dust be completely converted into little particle state in conjunction with water mist, and the little particle after water suction is in weight
Under the action of power, during freely falling body, drops in wet grey collecting tank 8, be in the form of a column down to let out to car from the bottom of device and arrange
System out.Make scene be truly realized dustless metaplasia to produce, it is poor to solve site work environment, and hot operation, condition be arduous, Ren Yuanliu
Move the problems such as big.
