Abstract
The utility model discloses a kind of Large-scale fire-electricity unit wet desulphurization renovation and improving device, comprise desulfurizing tower (1), desulfurizing tower (1) bottom is provided with slurry pool (6), desulfurizing tower (1) bottom is also provided with into mouth (9), enters mouth (9) and is positioned at slurry pool (6) top; Elementary spray assemblies (10), liquid collecting plate (12) and secondary spray assemblies (14) is once provided with from bottom to up in described desulfurizing tower (1); Described elementary spray assemblies (10) is communicated to slurry pool (6) by elementary carrier pipe (5).The utility model can promote the desulfurization degree of Large-scale fire-electricity unit wet desulphurization.
Description
Technical field
The utility model relates to a kind of Large-scale fire-electricity unit wet desulphurization renovation and improving device, belongs to technical field of environment protection equipment.
Background technology
In the fired power generating unit at some large-scale thermal power stations, because comburant can produce a large amount of sulfur-containing smoke gas after combustion, discharge again after therefore usually needing to carry out wet desulphurization.But existing wet desulphurization device is all carry out spray desulfurization in a desulfurizing tower.But existing desulfurizing tower generally can only reach 90% to 95% to the desulfurization degree of flue gas, therefore finally discharged amount of sulfur contenting in smoke is still higher, pollutes larger.
Utility model content
The purpose of this utility model is, provides a kind of Large-scale fire-electricity unit wet desulphurization renovation and improving device.It can promote the desulfurization degree of Large-scale fire-electricity unit wet desulphurization.
The technical solution of the utility model: Large-scale fire-electricity unit wet desulphurization renovation and improving device, it is characterized in that: comprise desulfurizing tower, be provided with slurry pool bottom desulfurizing tower, desulfurizing tower bottom is also provided with into mouth, enters mouth and is positioned at above slurry pool; Elementary spray assemblies, liquid collecting plate and secondary spray assemblies is once provided with from bottom to up in described desulfurizing tower; Described elementary spray assemblies is communicated to slurry pool by elementary carrier pipe.
In above-mentioned Large-scale fire-electricity unit wet desulphurization renovation and improving device, described liquid collecting plate is evenly equipped with multiple recessed collection funnel, the suspension of each collection funnel lower end has collection bowl, collection bowl is connected to the secondary slurries pond outside desulfurizing tower by recovery tube, secondary slurries pond is connected to secondary spray assemblies by secondary carrier pipe.Multiple collection funnel be evenly arranged, not only can make the flue gas in tower be uniformly distributed, and suitably can control the floor height on absorption tower, have certain economy.
In aforesaid Large-scale fire-electricity unit wet desulphurization renovation and improving device, described slurry pool is connected with slurry supply tank by supply pipe.
Compared with prior art, the utility model, by arranging upper and lower two-stage spray assemblies in desulfurizing tower, can carry out multiple spray desulfurization to flue gas, and the slurry of spray can recycle.The flue gas desulphuization rate that Large-scale fire-electricity unit can be made to discharge of device of the present utility model rises to more than 98%.And, simple for structure, advantage of lower cost of the present utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of liquid collecting plate.
Being labeled as in accompanying drawing: 1-desulfurizing tower, 2-level carrier pipe, 3-recovery tube, 4-secondary slurries pond, the elementary carrier pipe of 5-, 6-slurry pool, 7-supply pipe, 8-slurry supply tank, 9-enters mouth, the elementary spray assemblies of 10-, 11-collects bowl, 12-liquid collecting plate, 13-collection funnel, 14-level spray assemblies.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.Large-scale fire-electricity unit wet desulphurization renovation and improving device, as shown in Figure 1: comprise desulfurizing tower 1, is provided with slurry pool 6 bottom desulfurizing tower 1, desulfurizing tower 1 bottom is also provided with into mouth 9, enters mouth 9 and is positioned at above slurry pool 6; Elementary spray assemblies 10, liquid collecting plate 12 and secondary spray assemblies 14 is once provided with from bottom to up in described desulfurizing tower 1; Described elementary spray assemblies 10 is communicated to slurry pool 6 by elementary carrier pipe 5.Described liquid collecting plate 12 is evenly equipped with multiple recessed collection funnel 13, as shown in Figure 2.The suspension of each collection funnel 13 lower end has collects bowl 11, and collection bowl 11 is connected to the secondary slurries pond 4 outside desulfurizing tower 1 by recovery tube 3, secondary slurries pond 4 is connected to secondary spray assemblies 14 by secondary carrier pipe 2.Described slurry pool 6 is connected with slurry supply tank 8 by supply pipe 7.
Operation principle of the present utility model: flue gas enters at the bottom of the tower of desulfurizing tower from entering mouth, through the first order spray desulfurization of elementary spray assemblies during rising, and spray slurry (from slurry pool) out falls into the slurry pool of bottom, define first size circulations; Then flue gas continues to rise, pass from the collection funnel of liquid collecting plate, top due to liquid collecting plate has slurry to fall, therefore slurry can form water curtain at collection funnel place, flue gas has also carried out desulphurization reaction to a certain degree through in the process of water curtain, when flue gas continues to rise, is subject to again the second level spray desulfurization of secondary spray assemblies, and spray slurry (from secondary slurries pond) is out collected bowl and has been recovered to slurry pool, define second size circulations.And slurry supply tank can also carry out supply to the loss in slurry pool.
