Description
Technical field
The utility model is related to gas dust removal system, more particularly to a kind of Ou Ye stoves stock gas dust arrester.
Background technology
The predecessor of Ou Ye stoves is COREX stoves, as state-of-the-art COREX in the world, is moved from Baosteel Luojing to eight steel
After a series of process and technology innovation, possess the technology features of itself, therefore COREX stoves are renamed as Ou Yelu.
COREX producer gas system can be roughly divided into 5 subsystems：Generation coal gas, reducing gas, cooling coal gas, superfluous coal gas, furnace roof coal
Gas system.The raw coke oven gas produced by gasification furnace is referred to as occurring coal gas, and temperature is between 980 DEG C~1100 DEG C, wherein containing a large amount of
Dust.Generation coal gas is divided into two parts after hot cyclone separator dedusting, and a part is passed through in shaft furnace, and another part passes through
It is divided into two-way after cooled coal gas padding washing device, wherein coal gas is cooling coal gas all the way, it first passes through the adjustable Wen of cooled coal gas and washed
Wash device and further remove chalk dust removing, then pressurizeed by gas compression station.Cooling coal gas after pressurization is divided into three tunnels, mainly to coal and
The distributing device of ore deposit and the coal gas produced to gasification furnace are cooled down, and the gas temperature made into shaft furnace reaches 850 degree of requirement.
Coal gas into shaft furnace is referred to as reducing gas, occurs gas-solid base reduction reaction, the gas produced after reaction with iron ore
Body becomes stock gas.Stock gas is after coal gas padding washing device, and temperature declines to a great extent, and moisture content and pressure also will
Decline, the content of dust also greatly reduces；Push up coal gas and enter adjustable Venturi Scrubber after the coal gas padding washing device of top, it is right
Dust in stock gas carries out further cleaning depositing dust, and dehydration makes top gas quality meet user's request.
The top coal gas system of COREX coal gas systems has the following disadvantages：1）The middle and upper part for being arranged on COREX stove pylons takes
Substantial amounts of space, making the whole height of pylon increases, positioned at 60 meters of level above.2）Water consumption increase, sewage disposal expense increases
Plus, increase pig iron cost.3）For wet dedusting, gas temperature is reduced, is unfavorable for environmental protection and energy saving.4）It is unfavorable for TRT efficiencies
Play.5）Height is too high to be unfavorable for repair and maintenance.
The content of the invention
The purpose of this utility model is to provide a kind of Ou Ye stoves stock gas dust arrester, can change existing furnace roof
The antenna height that coal gas system is present is high, and water consumption is big, power consumption is big, the problem of be unfavorable for repair and maintenance, solves COREX coal gas systems
Top coal gas system exist many deficiencies, it is ensured that production be normally carried out.
The utility model solves the technical scheme that its technical problem used：A kind of Ou Ye stoves stock gas dedusting dress
Put, including reduction furnace, reduction furnace furnace roof sets the exhaust stack for carrying diffusion valve, and exhaust stack is connected to gravitational precipitator, gravity
Dust remover roof respectively connected gravity exhaust stack and raw coke oven gas pipeline with gravity diffusion valve, and raw coke oven gas pipeline connects respectively
Then raw coke oven gas stop valve and dry-method dust-removal device, the port of export of dry-method dust-removal device set clean coal tracheae, clean coal tracheae
On flow control valve, purified gas stop valve and blank-plate valve are installed successively, described raw coke oven gas stop valve is blind by raw coke oven gas
Plate valve is connected to raw coke oven gas and diffuses valve group, and raw coke oven gas diffuses valve group and is connected to raw coke oven gas exhaust stack by raw coke oven gas branch pipe(tube).
The utility model is in use, perpendicular stock gas is entered by being exported after preheating and reduction ore by raw coke oven gas pipeline
Gravitational precipitator carries out rough dedusting, and this gas temperature is controlled at 100-280 DEG C, and coal gas enters cloth bag as derived from gravitational precipitator
Dedusting carries out fine dedusting, produces purified gas, generates electricity or is used to user into TRT.If meeting gas temperature is more than 280 DEG C, can
Diffused by raw coke oven gas exhaust stack, while cutting off cloth bag inlet valve, reach the purpose of protection cloth bag.The utility model stock gas
The trial production stage of dedusting 69 days proves that gas temperature can be controlled below 280 DEG C, and by trial production, this stock gas is removed
Dirt device can meet the coal gas processing needs of Ou Ye stoves completely, instead of wet method top coal gas padding washing device and adjustable Venturi tube
The dedusting function of washer, significantly reduces the setting height(from bottom) of coal gas processing device, meets Ou Yelu production needs.
Brief description of the drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is attachment structure schematic diagram of the present utility model.
Embodiment
A kind of Ou Ye stoves stock gas dust arrester, as shown in figure 1, including reduction furnace 17, the furnace roof of reduction furnace 17 is set
Exhaust stack 2 with diffusion valve 1, exhaust stack 2 is connected to gravitational precipitator 5, and the top of gravitational precipitator 5 respectively connected with weight
The gravity exhaust stack 4 and raw coke oven gas pipeline 6 of power diffusion valve 3, raw coke oven gas pipeline 6 respectively connected raw coke oven gas stop valve 11 and
Dry-method dust-removal device 12, the port of export of dry-method dust-removal device is set is installed with stream successively on clean coal tracheae 13, clean coal tracheae 13
