Technical field
The utility model belongs to auxiliary device of blast furnace for blast furnace more particularly to a kind of dustless spray equipment for device for dust remover of blast furnace.
Background technology
The dustless shower water of device for dust remover of blast furnace, which breaks through journey, is：Water is opened when gravitational precipitator puts ash and rushes feed-water valve, water is passed through
Spraying ring pipe inside water punching, sprays the gas ash of releasing, dust-proof so as to achieve the purpose that.Dust-proof shower water rushes structure
It is that shell is hollow cylinder, cylindrical central part installation and repairing manhole, inside is that a cone tip is welded on shell upward
Inside, gas ash between cone lower edge and outer casing inner wall by flowing through.Spraying ring pipe is installed in the lower part of cone.Interior cone
Effect be make releasing gas ash formed cascade, thus can spraying ring pipe spray water just readily penetrate through flowing
Grieshoch makes the gas ash of outflow deduster is moist to bond, so as to reach dust-proof effect.
It fetches water due to may turn on furnace roof when blast furnace roof temperature is high, water will gasify in furnace roof, and as coal gas flows into
Enter deduster and be deposited in deduster grey body surface, inside deduster ash through moisture under the action of gravity and pressure, just
Grey block can be formed, ash block will flow into the gap of cone lower edge and outer casing inner wall with ash when deduster puts ash, if grey block
Larger to block cleaning door, the lighter causes ash to slip to become smaller, and severe one causes cleaning door all to block.General processing method is to open
Four apertures outside water punching carry out handling grey block, but due to bad environments at cleaning door, six bolts of mounting flange are difficult
It unloads, is to employ gas welding to cut open every time, processing time is very long, largely consumes man power and material.
The content of the invention
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of dustless spray for device for dust remover of blast furnace
Shower device, the easily upon opening closing of inspection manhole is convenient to overhaul, while can reduce blocking frequency again.
To achieve the above object, the utility model is achieved through the following technical solutions：
A kind of dustless spray equipment for device for dust remover of blast furnace, including shell, inspection manhole, cone, spraying ring pipe, maintenance
Manhole is arranged in the middle part of shell, and cone tip is welded inside the shell upward, and the lower part of cone is equipped with spraying ring pipe, and feature exists
In the spacing of the cone lower edge and outer casing inner wall is 48-52mm；The water spraying direction of spraying ring pipe and the angle of horizontal direction
For 1 ° -20 °；Inspection manhole includes pin plate, cotter way, capping, pedestal, steel pipe, and steel pipe one end is welded with shell, and the other end, which is fixed, to be connected
Pedestal is connected to, the through hole being connected with enclosure, pedestal both sides of the edge welding cotter way are equipped among pedestal, capping is consolidated with pin plate
Fixed connection, capping outer diameter are more than through-hole diameter, pin plate and cotter way grafting.
The inspection manhole radial equipartition is in shell.
The capping is equipped with sealing ring.
The cotter way is L-shaped structure.
The pin plate section is wedge shape wide at the top and narrow at the bottom, and the contact surface of pin plate and cotter way is inclined-plane.
Compared with prior art, the beneficial effects of the utility model are：
It is simple for the dustless spray equipment overall structure of device for dust remover of blast furnace, spraying effect is improved, grey block is reduced and blocks
Phenomenon, convenient for either on or off inspection manhole, easy cleaning ash block improves work efficiency.Pin plate can be realized with cotter way grafting
The closing of inspection manhole, the phenomenon that avoiding occurring not opening due to corrosion.Meanwhile the setting of steel pipe can also avoid grey block direct
Inspection manhole is contacted, extends the service life of inspection manhole.The water spraying direction of spraying ring pipe is slightly offset from horizontal direction, it is possible to increase
Spray area improves spraying effect.Cone lower edge and the spacing of outer casing inner wall are 48-52mm, you can facilitate the whereabouts of gas ash,
The penetration by water ash curtain that spraying ring pipe can be facilitated to spray again, the grey block of top will not be stuck in the gap that cone is formed with shell, prolong again
Repair rate is grown.

Specific embodiment
The utility model is described in detail with reference to Figure of description, it should be noted that the utility model
Implementation is not limited to following embodiment.
See Fig. 1, Fig. 2, a kind of dustless spray equipment for device for dust remover of blast furnace, including shell 1, inspection manhole 2, cone 3,
Spraying ring pipe 4, inspection manhole 2 are arranged on 1 middle part of shell, and 3 tip of cone is welded on upward in shell 1, and the lower part of cone 3 is equipped with
Spraying ring pipe 4,1 upper and lower ends of cylindrical outer casing are connected with flange 5, inspection manhole 2 include pin plate 9, cotter way 8, capping 6, pedestal 10,
Steel pipe 11,11 one end of steel pipe are welded with shell 1, and the other end is fixedly connected with pedestal 10, be equipped among pedestal 10 with inside shell 1
The through hole being connected, 10 both sides of the edge of pedestal welding cotter way 8, capping 6 are fixedly connected with pin plate 9, and it is straight that 6 outer diameters of capping are more than through hole
Footpath, pin plate 9 and 8 grafting of cotter way.3 lower edge of cone and the space D of 1 inner wall of shell are 48-52mm, in order to which grey block falls, simultaneously
Do not influence spraying effect again.The water spraying direction of spraying ring pipe and the angle of horizontal direction are 1 ° -20 °, it is possible to increase spray area, again
