Description
Technical field
This utility model relates to desulfurization and dedusting technology field, is specifically related to a kind of multitube Venturi.
Background technology
Desulphurization plant is a kind of cleaning equipment discharging the harmful substance such as dust, waste gas in field of industrial production.Wet process of FGD cleaning equipment is typically made up of to three layers of spray equipment and demister a layer in tower body and tower body at present.Being an entire body from the bottom to top in tower body, quickly arrive tower top after flue gas entrance tower body is interior, flue gas is the shortest with the time of contact of shower water, thus desulfurization and dedusting effect is not ideal, and the treating tail gas effect particularly with the big exhaust gas volumn of high concentration is more undesirable.
In order to reach " minimum discharge " standard, conventional desulfurizing tower is transformed, increase by one layer of multitube Venturi.
Venturi scrubber is a kind of efficient wet scrubber, is usually used in cooling high-temperature fume, dedusting, desulfurization.Flue gas mixes mutually with high velocity stream flow through venturi throat (i.e. at mid diameter minimum) and radial inflow, and the solid particle in gas is wet, and harmful gas is absorbed, subsequently into demister except mist dedusting.
Dust-removal and desulfurizing process conducted in Venturi scrubber, can be divided into atomization, absorb, condense and remove four steps of mist, and former three is carried out in Venturi tube, except mist is carried out during later.In collapsible tube and trunnion, the relative velocity between gas-liquid two-phase is very big, the drop ejected from nozzle, and under high velocity air impacts, atomization becomes thinner droplet further.Meanwhile, gas is completely saturated by solution institute, and the air film of grit surface attachment is broken through, and makes grit be readily wetted by water, and meanwhile in flue gas, SO2 air film and absorbent liquid film touch opportunity are bigger, and mass tranfer coefficient becomes big desulfurized effect and reaches to promote.In anemostat, the reduction of air velocity and the rise of pressure, make this cohesion with grit as the nuclei of condensation occur faster.It is condensed into the dust-laden drop of bigger particle diameter, is just easy to be caught by the demister at rear.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, it is provided that a kind of multitube Venturi, in order to improve the desulfurization and dedusting effect of whole system.
For solving above-mentioned technical problem, the technical solution of the utility model is:
A kind of multitube Venturi, support card including multitube venturi upper face plate, multitube venturi and be fixedly arranged on the some Venturi tubes between multitube venturi upper face plate and multitube venturi support card, described Venturi tube is perpendicular to horizontal plane and arranges, described Venturi tube includes collapsible tube, trunnion and anemostat the most successively, described collapsible tube is fixedly arranged on multitube venturi and supports card upper surface, described anemostat is fixedly arranged on multitube venturi upper face plate lower surface, is equipped with serosity shower nozzle in the trunnion of some described Venturi tubes.
Preferably, some described Venturi tubes are Spaced distribution.
Preferably, the anemostat of described Venturi tube and the cross section of collapsible tube are circular or regular hexagon.
Compared with prior art, the beneficial effects of the utility model are: multiple Venturi tubes multilamellar arranged side by side is arranged, sulfur removal effectiveness is greatly promoted, the radial direction serosity that during work, flue gas sprays with the hole for water spraying of multitube venturi spray pipe network with high velocity stream flow through venturi throat mixes, the drop ejected from hole for water spraying, under high velocity air impacts, atomization becomes thinner droplet further, simultaneously, gas is completely saturated by solution institute, the air film of grit surface attachment is broken through, grit is made to be readily wetted by water, meanwhile in flue gas, SO2 air film increases with absorbent liquid film touch opportunity, mass tranfer coefficient becomes big desulfurized effect and promotes.In anemostat, the reduction of air velocity and the rise of pressure, make this cohesion with grit as the nuclei of condensation occur faster, be condensed into the dust-laden drop of bigger particle diameter, air-flow continues upwardly into mechanical centrifugal demister to be carried out except mist dedusting.
