Description
Technical field
The utility model relates to field of environment protection equipment, more particularly, relates to a kind of dry dedusting of converter diffusing chimney.
Background technology
Along with the continuous enhancing of environmental consciousness, converter that is newly-built and transformation adopts dry dedusting technology mostly.Mainly there is following problem in existing dry method dust diffusing chimney: 1. diffusing chimney top is without waste-heat recovery device, and the amount of heat that coal gas diffusion burning produces wastes, not energy-conservation; 2. diffusing chimney needs accessory external medium just can light the coal gas diffused, and running cost is high; 3. single diffusing chimney can not be erect separately, needs auxiliary frame to stablize.
Summary of the invention
The technical problems to be solved in the utility model is, provides a kind of dry dedusting of converter diffusing chimney.
The utility model solves the technical scheme that its technical problem adopts: construct a kind of dry dedusting of converter diffusing chimney, comprise the diffusing chimney, nitrogen induction apparatus, direct-fired portfire, high-efficiency waste heat recovery device and the thermophore that connect successively; Described diffusing chimney inlet duct is provided with captation; Closure plate is provided with in described diffusing chimney; Described diffusing chimney top is provided with Venturi meter, and described venturi inlet is provided with nitrogen induction apparatus; Described diffusing chimney top is provided with direct-fired portfire and high-efficiency waste heat recovery device; Described high-efficiency waste heat recovery device is connected by water-supply pipe and return water pipe with described thermophore.
In such scheme, described Venturi meter is built-in, is provided with Steel Sleeve outside it.
In such scheme, the diameter of described diffusing chimney reduces from the bottom up gradually.
Implement dry dedusting of converter diffusing chimney of the present utility model, there is following beneficial effect:
1. by arranging high-efficiency waste heat recovery device at diffusing chimney top, the heat that coal gas diffusion burning produces being reclaimed, producing a large amount of hot water and can be used as domestic hot-water or be used for heating.
2., by adopting direct-fired portfire, not needing external gas source just directly can light emission coal gas in chimney, decreasing running cost.
3. the utility model solves the problem that single diffusing chimney relies on auxiliary frame to erect separately, has saved cost, has had a extensive future.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the utility model dry dedusting of converter diffusing chimney.
Embodiment
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As shown in Figure 1, dry dedusting of converter diffusing chimney of the present utility model comprises the diffusing chimney 1, nitrogen induction apparatus 4, direct-fired portfire 6, high-efficiency waste heat recovery device 7 and the thermophore 8 that connect successively.
Diffusing chimney 1 inlet duct is provided with captation 2, for the water droplet in collecting entrance pipeline; Being provided with closure plate 3 in diffusing chimney 1, for collecting the rainwater in diffusing chimney 1, and preventing gas leak.
Diffusing chimney 1 top is provided with Venturi meter 5, and Venturi meter 5 entrance is provided with nitrogen induction apparatus 4, by the injection of medium pressure nitrogen gas, for forming negative pressure under accidental state in diffusing chimney 1, the coal gas injection remained in dry-dedusting system is gone out diffusing chimney 1.
Diffusing chimney 1 top is provided with direct-fired portfire 6 and high-efficiency waste heat recovery device 7; Direct-fired portfire 6 produces trapezoidal electric arc by high voltage electric, directly lights the coal gas of converter that diffusing chimney 1 exports; Produce a large amount of heat energy after coal gas of converter burning, reclaimed by high-efficiency waste heat recovery device 7; High-efficiency waste heat recovery device 7 is connected by water-supply pipe 9 and return water pipe 10 with thermophore 8, and thermophore 8 overcomes the shortcoming that coal gas of converter periodically diffuses burning, and lasting, stable externally provides hot water.
Venturi meter 5 adopts built-in, peripheral hardware Steel Sleeve.
Diffusing chimney 1 diameter reduces from the bottom up gradually, and this structure formation of diffusing chimney 1 has good stability, does not need by auxiliary frame, can erect separately, has saved cost.
Further, the height of diffusing chimney 1 is 60 ~ 80m (being generally 65m).
Further, the pressure of injection medium pressure nitrogen gas is 1.2 ~ 1.6MPa (being generally 1.4MPa).
Further, diffusing chimney 1 exports the concentration range 18% ~ 75% (being generally 60%) of CO in the coal gas of converter that can directly light.
Further, high-efficiency waste heat recovery device heat exchange efficiency 85% ~ 99% (being generally 95%).
Converter in dry dedusting of converter diffusing chimney of the present utility model is defined as: decarburization converter or dephosphorization converter or lava homogenizing furnace or stainless steel.Dry dedusting of converter diffusing chimney of the present utility model is applicable to 80t ~ 300t coal gas of converter ignition bleeding.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, also can make a lot of form, these all belong within protection of the present utility model.
