Description
Technical field
The utility model relates to sulfuric acid apparatus technical field, the sulfur furnace rain cover structure of specifically a kind of improvement.
Background technology
Sulfur furnace is the visual plant in sulphur-burning sulphuric acid plant, in stove, working temperature is up to 1100 DEG C, utilize the heat-blocking action of refractory lining that the temperature outside furnace wall is reduced to the allowable value of box hat material, and consider the low temperature corrosion effect of sulfurous gas, box hat tube wall temperature is set in relatively high temperature.
See Fig. 1, to dissipated heat gas in environment, rain cover is set for preventing the direct spray body of heater high temperature outer wall of rainwater at the first half of sulfur furnace.Traditional rain cover is whole semi-circular structure, and when megathermal climate, a large amount of hot gas of furnace roof gathers and can not distribute in time, easily causes the accident of furnace wall overtemperature.
Therefore, need to design and a kind ofly can reach the sulfur furnace rain cover structure of improvement that rainproof effect does not affect again furnace roof heat radiation.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind ofly can reach the sulfur furnace rain cover structure of improvement that rainproof effect does not affect again furnace roof heat radiation.
In order to achieve the above object, the utility model devises a kind of sulfur furnace rain cover structure of improvement, comprise sulfur furnace and rain cover, it is characterized in that: the center of top of sulfur furnace is provided with high-rise rain cover, the both sides of high-rise rain cover are respectively equipped with low layer rain cover, higher than the height of low layer rain cover, between the top layer of high-rise rain cover and the top layer of low layer rain cover, there is gap in the height of high-rise rain cover.
Described high-rise rain cover and described low layer rain cover are by web plate, spoke, backplate, screw, pre-welding plate and column composition, pre-welding plate is welded on the top of sulfur furnace, the top of pre-welding plate is connected with the bottom of column, the welded top of column has web plate, the top of web plate is fixed with spoke and backplate from bottom to up successively, web plate, adopts be screwed between spoke and backplate.
Described pre-welding plate is the pre-welding plate of steel plate.
Described column is angle steel column.
Described web plate is steel plate web plate.
Described spoke is band steel spoke, band steel spoke is drilled with screw threaded through bores, and band steel spoke has radian.
Described backplate adopts aluminium sheet backplate.
The utility model compared with the existing technology, devise height two-layer rain cover, the high wall surface temperature effectively preventing sulfur furnace shell to have is drenched with rain and to dissipated heat gas in environment, there is the superperformance that warm air distributes smoothly to furnace roof portion simultaneously, avoid a large amount of hot gas to gather accident that furnace roof causes furnace wall overtemperature.The utility model adopts angle steel, band steel skeleton construction, makes and simple installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is rain cover structural representation of the present utility model.
Be sulfur furnace see Fig. 1-3,1; 2 is rain cover; 2-1 is high-rise rain cover, and 2-2 is low layer rain cover, and 3 is web plate; 4 is spoke; 5 is backplate; 6 is screw; 7 is pre-welding plate; 8 is column.
Embodiment
Now by reference to the accompanying drawings the utility model is described further.
See Fig. 2 and Fig. 3, the utility model is a kind of sulfur furnace rain cover structure of improvement, comprises sulfur furnace and rain cover.The center of top of sulfur furnace 1 is provided with high-rise rain cover 2-1, the both sides of high-rise rain cover 2-1 are respectively equipped with low layer rain cover 2-2, higher than the height of low layer rain cover 2-2, between the top layer of high-rise rain cover 2-1 and the top layer of low layer rain cover 2-2, there is gap in the height of high-rise rain cover 2-1.
In the utility model, high-rise rain cover 2-1 and low layer rain cover 2-2 forms by web plate 3, spoke 4, backplate 5, screw 6, pre-welding plate 7 and column 8, pre-welding plate 7 is welded on the top of sulfur furnace 1, the top of pre-welding plate 7 is connected with the bottom of column 8, the welded top of column 8 has web plate 3, the top of web plate 3 is fixed with spoke 4 and backplate 5 from bottom to up successively, web plate 3, adopts screw 6 to fix between spoke 4 and backplate 5.
Pre-welding plate 7 is the pre-welding plate of steel plate, forms by with the steel plate cutting of the identical material of sulfur furnace 1 box hat.
Column 8 is angle steel column, is formed by angle steel cutting.
Web plate 3 is steel plate web plate.
Spoke 4 is band steel spoke, is processed by band steel, band steel spoke is drilled with screw threaded through bores, and the band steel spoke of circumference is pre-bent to required radian.
Backplate 5 adopts aluminium sheet backplate, after treating rain cover frame installation, is screwed on it.
The utility model operationally, high-rise rain cover 2-1 and low layer rain cover 2-2 plays the effect of anti-rain, thus prevent sulfur furnace shell owing to being drenched with rain the situation to dissipated heat gas in environment, gap between high-rise rain cover 2-1 and low layer rain cover 2-2 is used for loses heat air-flow, avoid a large amount of hot gas to gather accident that furnace roof causes furnace wall overtemperature.
