Abstract
The utility model discloses a spraying and desulfurizing tower capable of preventing wall flow. The spraying and desulfurizing tower comprises a tower body, wherein the tower body is provided with a spraying layer and a smoke inlet; a wall flow plate which is of an annular structure is arranged below the spraying layer and fixed at the inner side of the wall of the spraying and desulfurizing tower; and the wall flow plate is provided with a plurality of small holes along the annular direction. The spraying and desulfurizing tower has the advantages that the wall flow plate is arranged below the spraying layer of the spraying and desulfurizing tower, so that a desulfurization solution is redistributed, and furthermore, the utilization ratio of the desulfurization solution is effectively increased, the desulfurization efficiency of the desulfurizing tower is increased, the slurry quantity of a circulating pump is reduced, and a higher desulfurization effect is achieved.
Description
Technical field
The utility model relates to a kind of spray desulfurizing tower, and specifically a kind of anti-wall flow spray desulfurizing tower, belong to the spray desulfurizing tower field.
Background technology
Spray column has long history as a kind of ancient desulphurization plant, rely on simple in structure, be convenient to make processing, be convenient to take anti-corrosion measure, resistance is little, the advantages such as less scaling obstruction are occupied absolute advantage at desulfuration field, its groundwork principle is that the spray absorber main body is cylindrical tower, dispose spraying layer and high-efficiency demisting apparatus in tower, slurries pass through the high-efficiency atomizing nozzle atomization in absorption tower, form good gas-liquid contact reaction interface, after flue gas enters in tower, in tower, at the uniform velocity rise, with vaporific hydrojet, carry out contacting efficient mixing the comprehensively, remove SO
2deng sour gas, the flue gas after desulfurization is discharged after demister.But existing spray column exists the doctor solution of spray, in tower body, the problem of wall flow phenomenon can occur in application process, local desulfuration efficiency is descended serious, thereby makes generally desulfuration efficiency reduce.
The utility model content
In order to address the above problem, the utility model has designed a kind of anti-wall flow spray desulfurizing tower, by wall stream plate is set below the spraying layer of desulfuration spray tower, thereby make doctor solution distributed the utilization rate that has effectively improved doctor solution, improved the desulfuration efficiency of desulfurizing tower, reduce circulating pump slurries amount, obtained higher desulfurized effect.
The technical solution of the utility model is:
A kind of anti-wall flow spray desulfurizing tower, comprise tower body, described tower body is provided with spraying layer and advances mouth, described spraying layer below is provided with wall stream plate, described wall stream plate is loop configuration, be fixed on the tower wall inboard of spray desulfurizing tower, described wall stream plate is provided with some apertures along circumferential direction, makes distribution of slurry evenly and does not increase equipment resistance.
Further, described wall stream plate and desulfurizing tower wall inclination angle at 45 ° are fixed.
Further, described wall stream plate is monolithic steel alloy structure, and in quantity and spray column, the quantity of spraying layer adapts.
The utility model is to have increased wall stream plate on the basis of original spray column below every layer of spraying layer, wall stream panel assembly adopts corrosion-resistant, impact-resistant alloy material is installed one week and downward-sloping layout along the tower wall below spraying layer in tower, the slurries of collecting and reallocating and flow down along the tower wall, the function that is equivalent to the tower wall nozzle, the slurries flue gas that risen entrainments again, effectively improved the utilization rate of absorbent slurry, improved the gas-liquid exchange of close tower wall, gas/liquid is more evenly distributed, rising flue gas stream near the tower wall is had and stops, polycondensation, force air-flow to flow to the spray column center, increased the gas-liquid contact area, utilization rate and the SO of desulfurizing agent have greatly been improved
2removal efficiency.
The utility model is compared and is had following features with existing spray column:
(1) make the spray liquid sub-distribution again of wall stream, improved desulfuration efficiency;
(2) under the condition of same liquid-gas ratio, there is higher desulfuration efficiency;
(3) compare equal desulfuration efficiency, the utility model can reduce by 5～10% circulating pump slurries amount.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment spray desulfurizing tower;
