Description
Technical field
The utility model relates to a kind of ore deposit hot stove dust treatment equipment, is specifically related to a kind of ore deposit hot stove tapping hole dust arrester.
Background technology
Ore deposit hot stove tapping hole flue dust has characteristics such as jet power is strong, emitted dose big, inorganization, is spurting to penetrate and diffusion rapidly from tapping hole under the effect of hot pressing and furnace pressure, spreads in whole tapping hole place, causes serious environmental to pollute.Therefore, this inorganization flue dust is in need of immediate treatment.
Usually the dust treatment mode is to carry out smoke catching at the iron oral region, smoke catching mode determined substantially to tap a blast furnace air quantity, dust removing effects, system's investment and the operating cost of oral region dedusting, and influential to casthouse equipment type selecting, flushing and casting etc.Existing iron oral region smoke catching mode exists investment and running cost height, smoke catching weak effect to some extent, hinder shortcoming such as flushing and casting.The core prerequisite of ore deposit hot stove tapping hole smoke catching is the ordinary production that can not influence the hot stove in ore deposit.The difficulty of tapping hole smoke catching mainly contains: design of hot stove tuyere platform in most ore deposits that go into operation at present (1) is only considered arts demand and is not considered the needs of dedusting, the smoke catching cover can only be arranged in the nearer zone of distance iron mouth, the instantaneous smoke catching district of going out of flue gas meeting by the iron mouth ejects very easily causes the generation of flue dust out-of-control phenomenon; (2) the hot stove of large ore generally all requires the tapping hole planarization, makes the trend of the pattern of fume trap cover and airduct be subjected to the restriction of factor such as attractive in appearance, captures effect and is difficult to reach environmental requirement.
The utility model content
The purpose of this utility model is to propose a kind of ore deposit hot stove tapping hole dust arrester, has solved existing ore deposit hot stove tapping hole cleaner smoke catching weak effect, investment is big, operating cost is high, and the installation of equipment hinders problems such as flushing and casting.
For reaching this purpose, the utility model by the following technical solutions:
A kind of ore deposit hot stove tapping hole dust arrester, comprise the smoke catching cover, described smoke catching cover is installed in the oral-lateral that taps a blast furnace of the hot stove in ore deposit, described smoke catching cover is connected to the dust preprocessor by flue, described dust preprocessor exit is connected with air-introduced machine, is connected with fiber bag precipitator behind the described air-introduced machine.
On the basis of aforementioned schemes, preferred scheme is: described flue is divided into two sections, and wherein long near the flue of smoke catching cover is 10m, the outer thick corrosion resistant plate of 8mm that adopts, liner adopts refractory brick, half section long 80m of flue in addition, the 6mm corrosion resistant plate of employing Q235.
On the basis of aforementioned schemes, preferred scheme is: described smoke catching cover material is Q235 carbon steel.
On the basis of aforementioned schemes, preferred scheme is: described preprocessor adopts adjustable dust preprocessor.
The equipment that the utility model adopts is simple, structure is reasonable, it is compact to arrange, the operation that does not influence the tapping hole operation of the hot stokehold of smelting process and ore deposit is used in the installation of dust arrester; The smoke catching cover space that tapping hole arranges is bigger, can effectively reduce the tapping hole flue-gas temperature, need not to arrange heat exchanger to reduce temperature in addition; The dust arrestment rate height, the hot stove oral-lateral that taps a blast furnace is arranged the smoke catching cover in the ore deposit, has improved dust arrestment rate, during actual job, capture rate reaches 98%; Economical and energy saving, and make the dirt source concentrate, the flue dust diffusion area is little, and the required processing energy consumption of system is low, effectively reduces initial outlay and the operating cost of equipment.
Description of drawings
Fig. 1 is the utility model overall structure module figure.
Among the figure:
1, the hot stove in ore deposit; 2, smoke catching cover; 3, air-introduced machine; 4, flue; 5, dust preprocessor; 6, fiber bag precipitator.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Fig. 1 is the module map that the utility model is specifically implemented structure.
Among the figure, the oral-lateral that taps a blast furnace of hot stove 1 arranges smoke catching cover 2 in the ore deposit, and described smoke catching cover 2 adopts semi-enclosed smoke catching cover, and material is selected Q235 carbon steel for use; The flue gas of tapping hole comes out to enter flue 4 from smoke catching cover 2, and flue 4 is divided into high temperature section and common section, and high temperature section adopts the 6mm corrosion resistant plate, and liner is castable refractory, the 6mm corrosion resistant plate of common section Qr35d; High temperature segment length 10m, common segment length are 80m; Flue 2 is connected to dust preprocessor 5, dust preprocessor 5 has adopted adjustable dust preprocessor, this preprocessor is characterised in that spiral case whirlwind tube is installed on the stud cylinder, spiral case whirlwind tube and shellfish word ash bucket are overlapping to intersect, the connected entrance place that spiral case whirlwind tube and shellfish word ash bucket intersect is provided with board-like control valve, ash-laden gas is through the rotation of spiral case whirlwind tube, and the big dust particle in the flue gas is split under action of centrifugal force in the shellfish word ash bucket, and other flue gas is discharged from the air outlet of stud cylinder.Characteristics such as this preprocessor has simple in structure, and is practical are applied to make dust pelletizing system more reasonable after the industrial production, and dust removing effects is more obvious.
Cyclone dust collectors are for removing the dust of particle diameter more than the 5-10 micron, and its efficient is higher, generally is not less than 90%.Flue gas treating capacity (investigation gas flow) raises, and then efficiency of dust collection reduces, and the pressure loss increases (can further reduce efficiency of dust collection but close minor valve by regulating the loss of air bleeding valve size controlled pressure).
Be connected to fiber bag precipitator 6 after the described dust preprocessor 5, and be equipped with for the air-introduced machine 3 of flue dust being sent into deduster in dust preprocessor 5 exits, after process preprocessor 5 carries out the flue gas particle classification, flue dust can directly be sent into fiber bag precipitator 6 by air-introduced machine 3, dust is trapped in the filter bag, the flue gas that purifies enters atmosphere through dust remover roof, and the micro mist under the ash bucket is gone into bag output automatically by machinery.
Fiber bag precipitator is applicable to and captures tiny, dry, non-fiber dust.Filter bag adopts the alkali-free glass fibre filter cloth of weaving to make, utilize the filtration of fabric that dusty gas is filtered, when dusty gas enters sack cleaner, big, the heavy dust of particle, because the effect of gravity settles down, and falls into ash bucket, contain gas than fine dusts by filtrate the time, dust is purified gas by detention.
The equipment that the utility model adopts is simple, structure is reasonable, it is compact to arrange, the operation that does not influence the hot casthouse equipment of iron-smelting process and ore deposit is used in the installation of dust arrester; The smoke catching cover space that tapping hole arranges is bigger, can effectively reduce the tapping hole flue-gas temperature, need not to arrange heat exchanger to reduce temperature in addition; The dust arrestment rate height, the hot stove oral-lateral that taps a blast furnace is arranged the smoke catching cover in the ore deposit, has improved dust arrestment rate, during actual job, capture rate reaches 98%; Economical and energy saving, and make the dirt source concentrate, the flue dust diffusion area is little, low initial outlay and the operating cost that effectively reduces equipment of disposal ability that system is required.
