Abstract
The present invention relates to a kind of Isa furnace water-cooling screen, including import header, outlet header and heating surface tube, heating agent imports from import header, flow out from outlet header after heating surface tube heat exchange, water-cooling screen is by Flange joint expansion joint between water-cooling screen and changeover portion, and described heating surface tube is for being horizontally disposed with.The Isa furnace water-cooling screen of the present invention, its heating surface tube, for being horizontally disposed with, uses round steel welding between heating surface tube, its distance is less, and whole water-cooling screen defines an organic whole, and the heat-transfer effect of heating surface is remarkably reinforced.The heating surface tube connection and reasonable arrangement of this water-cooling screen, extends the service life of water-cooling screen.
Description
Technical field
The present invention relates to the UTILIZATION OF VESIDUAL HEAT IN parts on a kind of non-ferrous smelting furnace flue, particularly relate to one
Isa furnace water-cooling screen.
Background technology
Water-cooling screen is UTILIZATION OF VESIDUAL HEAT IN parts on non-ferrous smelting furnace flue.The cigarette that this part is contacted
Temperature is the highest, generally about 1200 DEG C, so in flue, water-cooling screen is that heat transfer condition is disliked most
One of bad parts.Just due to this, so the design of water-cooling screen is particularly important.
The arrangement of water-cooling screen heating surface of the prior art is for arrange up and down, and bottom is four imports
Header, top is four outlet headers, and heating surface is arranged between import and export header.Due to heating surface
It is that up-small and down-big prismoid shaped is arranged, as it is shown in figure 1, the distance between event heating surface tube 3 is the most downward
The most sparse, the area mending plate 6 of needs is the biggest, and heat-transfer effect is the poorest.It is known that in flue
The temperature of flue gas is the most downward more high, the consequence brought be place heat-transfer effect on the contrary that flue gas is the highest
Difference, it is clear that this layout is the most quite reasonable.Due to this irrational layout, traditional water-cooling screen longevity
Order the shortest.
Summary of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art, it is provided that a kind of heating surface tube level sets
The Isa furnace water-cooling screen put.
For achieving the above object, the technical solution used in the present invention is as follows.
A kind of Isa furnace water-cooling screen, including import header, outlet header and heating surface tube, heating agent is from entering
Mouth header imports, and flows out from outlet header after heating surface tube heat exchange, and water-cooling screen passes through Flange joint
On expansion joint between water-cooling screen and changeover portion, described heating surface tube is for being horizontally disposed with.
Further, described heating surface tube is steel pipe.
Further, welded by round steel between described heating surface tube.
Further, sand seal device it is provided with between water-cooling screen and bell.
The invention has the beneficial effects as follows: the Isa furnace water-cooling screen of the present invention, its heating surface tube is that level sets
Putting, use round steel welding between heating surface tube, its distance is less, and whole water-cooling screen defines one to be had
The entirety of machine, the heat-transfer effect of heating surface is remarkably reinforced.The heating surface tube connection and reasonable arrangement of this water-cooling screen,
Extend the service life of water-cooling screen.

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with the accompanying drawings
And the present invention is described in further detail by embodiment.Should be appreciated that described herein being embodied as
Example only in order to explain the present invention, is not intended to limit the present invention.
The Isa furnace water-cooling screen of the present invention as shown in Figures 2 and 3, collects including import header 1, outlet
Case 2 and heating surface tube 3, import header 1 is connected with heating surface tube 3 respectively with outlet header 2,
Recirculated water imports from import header 1, flows out from outlet header 3 after heating surface tube 3 completes heat exchange.
For preventing flue gas from revealing, between water-cooling screen and bell, it is provided with sand seal device 4；Water-cooling screen passes through transition
Section expansion joint flange 5 is connected on the expansion joint between water-cooling screen and changeover portion.
Fig. 4 is the heating surface tube structural representation of the Isa furnace water-cooling screen of the present invention, as shown in Figure 4,
Heating surface tube 3 is for being horizontally disposed with, vertical with flue gas direction F, and heating surface tube is steel pipe, heating surface tube
Welded by round steel 7 between 3.
The water-cooling screen of the present invention is horizontal tube design, and the distance between heating surface tube is less, heating surface tube
Between use round steel welding, whole water-cooling screen defines an organic whole, the heat transfer of heating surface effect
Fruit is remarkably reinforced.The life-span of water-cooling screen the most just extends much, and its life-span can reach tradition water-cooling screen
More than several times.
The foregoing is only presently preferred embodiments of the present invention, be not used for limiting the enforcement model of the present invention
Enclose；If without departing from the spirit and scope of the present invention, the present invention is modified or equivalent,
All should contain in the middle of the protection domain of the claims in the present invention.
