Abstract
Provided is a serous fluid internal circulation type heat exchange grille for a desulfurization tower. The serous fluid internal circulation type heat exchange grille for the desulfurization tower is characterized in that the serous fluid internal circulation type heat exchange grille for the desulfurization tower comprises a heat exchange grille body arranged in the desulfurization tower; the heat exchange grille body comprises a ring-shaped support and a plurality of heat exchange pipes arranged on the ring-shaped support in parallel. Compared with the prior art, the serous fluid internal circulation type heat exchange grille has the advantages that not only is the desulfurization effect improved, but also the temperature of sprayed serous fluid is lowered, and the safe operation of components inside the desulfurization tower and a serous fluid circulation pump is guaranteed.
Description
Technical field:
The present invention relates to a kind of environmental protection sulfur removal technology.
Background technology:
At present, in the oxidation stock tank of internal-circulation type desulfurizing tower, temperature is higher, and reality can reach 70-80 DEG C.Slurries saturated vapor pressure increases with the increase of fluid temperature, and the gas in slurries is constantly gasified.Slurries containing a large amount of bubble are recycled after pump aspirates and produce cavitation phenomenons, the impeller of grievous injury circulating pump, the assembly of mechanical seal; In addition, because slurries are circulated sprinkling, and gas-liquid contact is carried out with import high-temperature flue gas.Cannot lower the temperature to flue gas when slurry temperature is higher, cause high-temperature flue gas to destroy anticorrosion scale in desulfurizing tower, fiberglass equipment as demister etc., very easily cause as anticorrosion scale come off, the serious consequence such as demister caves in.
Summary of the invention:
Goal of the invention of the present invention is to provide one to promote desulfurized effect, reduce sprayed slurry temperature simultaneously, ensures the safe operation of desulfurizing tower inner part and slurry circulating pump
slurries internal-circulation type desulfurizing tower heat exchange grid.
The present invention is achieved in that the heat exchange grid comprising and being arranged in desulfurizing tower, heat exchange grid comprise ring support and be set in parallel on ring support several heat exchanger tubes.During work, heat exchange grid is fixed in desulfurizing tower by ring support, and the cooling liquid inlet of the heat exchanger tube of heat exchange grid is connected with the cooling fluid supply mouth on desulfurizing tower sidewall, and the cooling liquid outlet of heat exchanger tube is connected with the cooling fluid scavenge port on desulfurizing tower sidewall.Flue gas flows over heat exchange grid from lower to upper along desulfurizing tower, and slurries spray through heat exchange grid along desulfurizing tower from top to bottom, the sulfide contained by flue gas draw by slurries removing, meanwhile, the temperature of slurries lowers by heat exchange grid.
Heat exchange grid has two effects: 1, for lowering the temperature to high temperature slurries; 2, for expanding gas-liquid contact specific area, and rectification is carried out to gas-liquid two-phase, to promote mutual mixability.
Here, heat exchanger tube adopts the heat exchanger tube of acid and alkali-resistance, silicon carbide material that thermal conductivity factor is higher.
Compared with the prior art the present invention, has and can promote desulfurized effect, reduces sprayed slurry temperature simultaneously, ensures the advantage of the safe operation of desulfurizing tower inner part and slurry circulating pump.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the lateral plan of Fig. 1;
Fig. 3 is the schematic diagram of flue gas desulfurization.
Detailed description of the invention:
Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:
As shown in the figure, the present invention includes the heat exchange grid A be arranged in desulfurizing tower (not having in figure to show), heat exchange grid A comprise ring support 1 and be set in parallel on ring support 1 several heat exchanger tubes 2, heat exchange grid A is fixed in desulfurizing tower by ring support 1, the cooling liquid inlet of the heat exchanger tube 2 of heat exchange grid A is connected with the cooling fluid supply mouth on desulfurizing tower sidewall, the cooling liquid outlet of heat exchanger tube 2 is connected with the cooling fluid scavenge port on desulfurizing tower sidewall, as shown in Figure 3, flue gas flows over heat exchange grid A from lower to upper along desulfurizing tower, slurries spray through heat exchange grid A along desulfurizing tower from top to bottom, sulfide contained by flue gas draw by slurries removing, simultaneously, the temperature of slurries lowers by heat exchange grid A.
Heat exchanger tube 2 adopts the heat exchanger tube of the silicon carbide material that acid and alkali-resistance, thermal conductivity factor are higher.
