The spray tower is provided with the smoke uniformly-distributing and primary dust removing device, so that the smoke in the spray tower is in fast flow and uniformly distributed, the problem of the increased consumption of desulphurizing agent and substandard sulfur dioxide at the smoke outlet caused by the non-uniform concentration of the smoke in the inlet section of the spray tower can be avoided, and the removal rate of the sulfur dioxide is high.
Description
Technical field
The invention belongs to smoke eliminator technical field, relate to a kind of desulfurizing tower, especially a kind of spray column of new type purification flue gas.
Background technology
Desulfurizing tower is a kind of cleaning equipment that discharges the harmful substances such as dust, waste gas in field of industrial production, oneself has and in technology, adopted moisture film tower, packed tower, grid tower, perforated plate tower and water column tower etc. in the past, at present the most frequently used in wet desulphurization is the spray column equipment of gas-liquid counter current contact, and spray column technology still exists the optimization part that haves much room for improvement.
In technology in the past, the airflow uniform distribution mode that most of desulfurizing tower adopts is, inlet pipeline is downward-sloping air-supply at a certain angle, rely on air-flow self dilatation, diffusion and effect of inertia carry out air-flow distribution, but such airflow uniform distribution effect is limited, in tower, air-flow distributes still very inhomogeneous, the local wind speed of entrance opposite tower wall one side is excessive, and the serum density of this part region spray is little, mostly be sticking wall flow, so cause in part air-flow sulfur dioxide not removed completely, be just discharged from desulfurizing tower, simultaneously, the excessive demister that also can make of local wind speed can not well play a role, cause the serious phenomenon of chimney breast band liquid, both contaminated environment had also been wasted adsorbent.
By retrieval, not yet find the patent publication us relevant to patent application of the present invention.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of Novel desulfurization tower is provided, this desulfurizing tower is provided with flue gas even distribution and rough dusting device, can make the interior flue gas fluidised form of desulfurizing tower uniform fast, avoid the doctor solution consumption producing because desulfurizing tower entrance flue gas concentration is inhomogeneous to increase and exhanst gas outlet sulfur dioxide problem not up to standard.The inverted cone-shaped structure of flue gas even distribution and rough dusting device can be removed part flue dust, therefore flue dust clearance of the present invention is higher.
The present invention realizes by the following technical solutions:
A kind of spray column of new type purification flue gas, comprise smoke inlet, exhanst gas outlet, demister, spray equipment, slurry pool and oxidation unit, the bottom of described spray column arranges smoke inlet, the upper top of spray column arranges exhanst gas outlet, in spray column between smoke inlet and exhanst gas outlet, set gradually spray equipment and demister, in spray column below smoke inlet successively to being arranged with slurry pool and oxidation unit, in spray column, be connected with smoke inlet flue gas even distribution and rough dusting device are installed, this flue gas even distribution and rough dusting device are arranged at the below of spray equipment, flue gas even distribution and rough dusting device upper end are shaped with uniform outlet flue.
And, described flue gas even distribution and rough dusting device comprise upper and lower, the sealing of the bottom on top and the upper end of bottom coaxially links together, and top is that top is airtight, the hollow cylindrical of lower ending opening, and on top, radial equipartition interval is shaped with a plurality of exhanst gas outlets; Bottom is the hollow turbination of upper end, the equal opening in lower end.
And the exhanst gas outlet total open area of described flue gas even distribution and rough dusting device meets exit velocity and is not more than 10% of gas approach flue gas flow rate.
And the lower bottom end of described flue gas even distribution and rough dusting device immerses 1000mm in slurry pool.
And described spray equipment is 3 grades of spray equipments.
And the lower end that described exhanst gas outlet is connected with tower wall is higher than demister upper end 3000mm.
And described spray equipment is connected with slurry pool with spray pump by pipeline, oxidation unit is connected with oxidation fan by pipeline.
And described spray column is circular.
Advantage of the present invention and good effect are:
1, spray column of the present invention is provided with flue gas even distribution and rough dusting device, can make the interior flue gas fluidised form of spray column uniform fast, avoided the doctor solution consumption producing because spray column entrance flue gas concentration is inhomogeneous to increase and exhanst gas outlet sulfur dioxide problem not up to standard, sulfur dioxide removal rate is high, simultaneously, demister can play a role well, avoided the generation of the serious phenomenon of chimney breast band liquid, avoided contaminated environment, also saved adsorbent, save the energy, improved flue dust clearance.
2, spray column of the present invention is because flue gas even distribution and preliminary device are inverted cone-shaped, and inlet flue gas rotates rising therein, and flue dust obtains part removal, and flue dust clearance can reach 90%.
Accompanying drawing explanation
Figure l is each modular construction layout drawing of the present invention;
Fig. 2 is the flue gas even distribution of Fig. 1 and the structure enlarged diagram of rough dusting device.
The specific embodiment
For further understanding content of the present invention, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.It should be noted that, the present embodiment is descriptive, is not determinate, can not limit thus protection scope of the present invention.
A kind of spray column of new type purification flue gas, as depicted in figs. 1 and 2, in the present embodiment, spray column is circular, described spray column comprises smoke inlet 10, exhanst gas outlet 1, demister 2, spray equipment 3, slurry pool 6 and oxidation unit 9, the bottom of described spray column arranges smoke inlet, the upper top of spray column arranges exhanst gas outlet, in spray column between smoke inlet and exhanst gas outlet, set gradually spray equipment and demister, in the spray column below smoke inlet successively to being arranged with slurry pool and oxidation unit.The lower end that this exhanst gas outlet is connected with tower wall is higher than demister upper end 3000mm.In the present embodiment, this spray equipment is connected with slurry pool with spray pump 7 by pipeline, and in the present embodiment, spray equipment is 3 grades of spray equipments, and in the present embodiment, oxidation unit is connected with oxidation fan 8 by pipeline.
