Abstract
The utility model discloses a membrane-wall closed steelmaking electric stove gasification cooling flue, which is characterized in that at least three sections of single flues are sequentially and serially connected with each other to form an integral gasification cooling flue which is horizontally arranged in the length direction, and every two adjacent sections of single flues are connected with each other through a metal expansion joint; the peripheral wall of the single flue with the cross section being of a rectangular shape adopts a membrane wall tube window to form a closed flue wall; and the peripheral wall is divided into an upper heated surface, a lower heated surface, a left side heated surface and a right side heated surface, one end of the membrane wall tube of each heated surface is connected with an inlet distribution header through a corresponding connection pipeline, and the other end of the membrane wall tube of each heated surface is connected with an outlet converging header through a corresponding connection pipeline. The membrane-wall closed steelmaking electric stove gasification cooling flue overcomes the weaknesses of the original water-cooling flue that the pipe is easy to be corroded and the heat of the smoke gas cannot be adequately used, has high heat utilization rate and stable service life of the heated surfaces.
Description
Technical field
The utility model relates to a kind of steel-smelting electric furnace gasification cooling stack, refers more particularly to a kind of steel-smelting electric furnace gasification cooling stack of film type wall sealing.
Background technology
Electric furnace smelting is quite general at China's steel industry, is used to smelt the high-quality steel.Produce a large amount of heats in the electric furnace smelting process and discharge with flue gas, the sensible heat of flue gas accounts for about 20% of total energy consumption, and the sensible heat that reclaims flue gas can produce certain economic benefits.The heat transmission equipment that is connected electric furnace flue gas outlet at present is a water-cooled flue, in servicely has a following shortcoming: the heating surface tube wall temperature is low in (1) water-cooled flue, and pipe easily produces cold end corrosion, and service life is short; (2) water-cooled flue just reduces flue-gas temperature, obvious heat of smoke is not made full use of the Btu utilization rate variance.
The utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of steel-smelting electric furnace gasification cooling flue of film type wall sealing is provided, and has heat utilization ratio height, stable characteristics of heating surface tube life-span.
The technical solution of the utility model is, the structure of the steel-smelting electric furnace gasification cooling stack of described film type wall sealing is, it is contacted successively by at least three joint single hop flues at length direction and forms the gasification cooling stack that integral level is arranged, adopts the expansion of metal joint to connect between every adjacent two joint single hop flues; Cross section is that the wall all around of the single hop flue of rectangle adopts the membrane wall pipe to constitute hermetically-sealed construction, described wall all around is respectively top heating surface, bottom heating surface, left side heating surface, right side heating surface, and the corresponding connecting pipe of membrane wall pipe other end warp of each heating surface collects the case connection with exporting to compile to the membrane wall Guan Yiduan of each heating surface with the connection of import allocation set case through the connecting pipe of correspondence.
Below the utility model made further specify.
Referring to Fig. 1, the structure of the steel-smelting electric furnace gasification cooling stack of described film type wall sealing is, it forms the gasification cooling stack that integral level is arranged at length direction by at least three joint single hop flues 1 polyphone successively, adopts expansion of metal joint 3 to connect between every adjacent two joint single hop flues 1; Referring to Fig. 2, cross section is that the wall all around of the single hop flue 1 of rectangle adopts membrane wall tube panel 4 to constitute the walling of flue of sealing; As Fig. 3, described wall all around is respectively top heating surface 12, bottom heating surface 13, left side heating surface 11, right side heating surface 10, and the corresponding connecting pipe of membrane wall pipe other end warp of each heating surface collects case 9 connections with exporting to compile to the membrane wall Guan Yiduan of each heating surface with 8 connections of import allocation set case through the connecting pipe 7 of correspondence.
Referring to Fig. 4, many pipelines 2 that described membrane wall tube panel 4 can be arranged by axially parallel and the band steel 14 between every adjacent two pipelines are tightly connected and form; As Fig. 2, described membrane wall tube panel 4 arranged outside are through the buckstay 5 of 4 reinforcement effects of 6 pairs of membrane wall tube panels of support member, and are whole indeformable to guarantee single hop flue 1, expand and are not obstructed.
Gasification cooling stack of the present utility model matches with the electric furnace of steel-making enterprise, utilizes steel-smelting electric furnace institute discharged flue gas to produce steam and is used for generating.During actual motion, the steam glide path of described single hop flue 1 is: the recirculated water from drum at first enters import allocation set case 8, after four sides membrane wall tube panel 4 heat absorptions through top heating surface 12, bottom heating surface 13, left side heating surface 11, right side heating surface 10, compiling collection case 9 from outlet gathers and turns back to drum, the saturated vapor that produces is drawn by drum, is used for generating.Whole carbonated drink endless form adopts forced circulation, and according to the needs of structural configuration, gasification cooling flue is made up of more piece single hop flue in the longitudinal direction.
Described membrane wall tube panel 4 is used for absorbing the sensible heat generation steam-electric power of flue gas, because its tube wall temperature is higher than the flue gas dew point temperature, can not produce dew point corrosion, long service life simultaneously.
As known from the above, the utility model is a kind of steel-smelting electric furnace gasification cooling stack of film type wall sealing, has heat utilization ratio height, stable characteristics of heating surface tube life-span.
