Description
Technical field
The utility model relates to the wet purification equipment of steelwork converter coal gas, specifically is a kind of Annular Space Scrubber.
Background technology
At present, steelwork converter coal gas wet-type cleaning equipment adopts the two-stage venturi scrubber that flue gas is lowered the temperature and dust removal process more.Wherein, first order Venturi tube mainly is to the processing of lowering the temperature of high temperature dust flue gas, also plays the effect of thick dedusting simultaneously; Second level Venturi tube mainly plays smart dedusting.The characteristics of second level Venturi tube are by gas-liquid mixed at a high speed, catch the fine particle in the flue gas, reach qualified discharge standard.In converter production process, exhaust gas volumn changes, and regulates second level Venturi tube aditus laryngis aperture, can guarantee the production environment in workshop and final efficiency of dust collection.In the prior art, adopt second level Venturi tube to the processing of lowering the temperature of pneumatic steelmaking flue gas, the water consumption that exists second level Venturi tube aditus laryngis is big, the problem that efficiency of dust collection is low.
The utility model content
The purpose of this utility model provides a kind of Annular Space Scrubber, and to solve in the second level Venturi tube cooling dedusting during stage, water consumption is big, the problem that efficiency of dust collection is low.
The purpose of this utility model is to realize by following technical scheme.
The utility model is an Annular Space Scrubber, it is characterized in that: comprise spray section, top nozzle, following nozzle, Outer Taper, inner cone and diffuser;
The top of described washer is cylindrical member, at described washer internal upper part spray section is housed, top nozzle and following nozzle, and upper and lower arrangement of nozzles is in the axis centre of washer;
The bottom of described washer is a Tapered Cup, comprises Outer Taper, and inner cone and diffuser, inner cone are enclosed within the Outer Taper, has the slit between the two; Diffuser is positioned at the inner cone below.Flue gas enters from the top spray section, discharges from the bottom diffuser.
Comprise that also aqueduct, feed pipe and Outer Taper support.
Two nozzles on the utility model Annular Space Scrubber top, center arrangement up and down, injection direction is consistent with the flue gas direction, sprays vaporific particulate water smoke and fully mixes with flue gas, and tiny dust is caught simultaneously by droplet, and flue gas is continued cooling.In order to guarantee the dust removing effects of lowering the temperature, guarantee that water smoke and flue gas have sufficient incorporation time, the flow velocity of flue gas is relatively slow, and about 15 meter per seconds get final product.Because adopt atomizer, injection flow rate reduces greatly.The nozzle of existing second level Venturi tube generally adopts the side spray, and in order to reach dust removing effects, what water consumption will be big is many.
Inner cone and Outer Taper are arranged at the bottom of the utility model Annular Space Scrubber.Flue gas enters in the middle of the slit of inner cone and Outer Taper formation after lowering the temperature from spray section, and velocity of flue gas takes place to change suddenly, reaches 100 meter per seconds, and formation is turbulent, dashes under the effect at strong rapids, and drop fully mixes with flue gas, thereby obtains very high efficiency of dust collection.Through the flue gas of cooling and smart dedusting, discharge from the diffuser of Annular Space Scrubber bottom.In the Venturi tube of the existing second level, the high speed regions of turbulent flow is controlled on the point, and Annular Space Scrubber is to control on an anchor ring, therefore, can improve efficiency of dust collection greatly.
In sum, the utility model can using water wisely, can significantly improve efficiency of dust collection again.The utility model is suitable for the steelwork converter gas recovery system and similar site uses.

The specific embodiment
Be illustrated in figure 1 as the structural representation of this practical Annular Space Scrubber, comprise spray section 1, top nozzle 2, following nozzle 4, Outer Taper (with the inner surface work of cone) 7, inner cone (with the external surface work of cone) 8 and diffuser 9;
The top of described washer is cylindrical member, at described washer internal upper part spray section 1 is housed, top nozzle 2 and following nozzle about in the of 4, two nozzle 2,4 be arranged in the axis centre of washer; Supplied water by feed pipe 3, aqueduct 5 is derived water.
The bottom of described washer is a Tapered Cup, comprises Outer Taper 7, and inner cone 8 and diffuser 9, inner cone 8 are enclosed within the Outer Taper 7, have the slit between the two; Diffuser 9 is positioned at inner cone 8 belows, and Outer Taper supports 6 and is used to support Outer Taper 7.
Flue gas enters from the top spray section, after the cooling of top, flows out from the slit high speed that forms between Outer Taper 7 and the inner cone 8, discharges from bottom diffuser 9.
During the utility model work, from the high-temperature flue gas that steel-smelting revolving furnace smoke canal comes out, after the cooling of first order Venturi tube, gas temperature drops to about 70 ℃.Flue gas after the cooling enters Annular Space Scrubber from spray section 1.Top nozzle 2 and following nozzle 4 eject vaporific water curtain, when flue gas is continued cooling, catch dust in flue gas.Nozzle 4 is above aqueduct 5, and the current that eject can also be directly wash the inner cone 8 of Annular Space Scrubber bottom, prevent dust in flue gas fouling on inner cone 8.Owing to adopt the atomizer of two-stage up and down, reduced water consumption greatly, handle 26833Nm
3The exhaust gas volumn of/h, water consumption is approximately 45t/h.
The flue gas that handled on top enters the bottom of Annular Space Scrubber.The inner cone 8 and the Outer Taper 7 of bottom, according to the size of flue gas total amount, corresponding adjusting slit size between the two.During flue gas process slit, speed can reach 100 meter per seconds, forms turbulent flow, and the vapour-liquid two-phase is dashed under the effect at strong rapids, interaction, and drop is fully mixed with the dust of flue gas, and dust in flue gas content reduces greatly.Flue gas after handling from slit through diffuser 9, is discharged from the bottom.Flue-gas temperature after Annular Space Scrubber is handled is that concentration of emission reaches 50mg/Nm about 65 ℃
3
The utility model Annular Space Scrubber uses in 40 tons of converter gas recovery systems, replaces second level Venturi tube, and is stable, respond well.The operational factor of on-site measurement equipment is as follows:
Smoke treatment amount 26833Nm
3/ h
72 ℃ of entrance flue gas temperatures
63 ℃ of exit gas temperatures
Water consumption 45t/h
Concentration of emission 50mg/Nm
