Description
Technical field
The utility model relates to a kind of spraying device of desulfurizing tower, belongs to flue gas controller technical field.
Background technology
In recent years, the environmental problem of China is increasingly sharpened, and the especially atmosphere polluting problem such as haze, acid rain greatly affects
The life of people.Country implements new environmental protection policy, has formulated the new standard of thermal power plant's Air Pollutant Emission.Current east and
The thermal power plant of central plain area starts demonstration and the concentration of emission of SO2 is reduced to 35mg/Nm3, and this gives coal-fired thermal power industry band
Huge opportunities and challenges are carried out.
Wet Flue Gas Desulfurization Technology is one of coal-burning power plant's most popular dusty gas control technology, and wet flue gas takes off
Multiple spraying layer is arranged in the desulfuration spray tower stage casing that sulphur uses, and high-temperature flue gas passes through desulfuration spray tower, sprayed slurry from bottom to top
With convection type to flue gas injection after spray equipment atomization, to remove the harmful substances such as SO2 in flue gas.
For realizing the high desulfurization efficiency of more than 99.3%, need to design more than 4 layers spraying layers, but how can be existing
Improve desulfuration efficiency in the case of spraying layer quantity as far as possible, make flue gas sufficiently be washed on cross section in tower, be this
Field technical barrier for a long time.
Content of the invention
The utility model technical issues that need to address are: existing desulfuration spray tower spray equipment, desulfuration efficiency needs
Improve, especially on the premise of existing spraying layer quantity, how to improve desulfuration efficiency as far as possible.
The utility model takes techniques below scheme:
A kind of desulfuration spray tower spray equipment, is provided with at least one of which spraying layer, described spray in described desulfuration spray tower device
Drenching layer and including spraying supervisor 5, spray supervisor 5 both sides are provided with some spray arms 6, equipped with at least one spray on each spray arm
Mouth 7；Described desulfuration spray tower device sidewall, is positioned at below spraying layer and is provided with smoke inlet 2；On described spraying layer, away from flue gas
The nozzle quantity at the position of entrance is more than the nozzle quantity near smoke inlet position.
Further, described nozzle 7 is spiral nozzle.
Further, described spray supervisor 5 diameter in the horizontal direction reduces step by step.
Further, described spray arm 6 one end is arranged on spray supervisor 5, and the other end is fixedly connected on de-after sealing
On the madial wall of sulphur spray column, spray arm 6 is obliquely installed along spray supervisor's 5 bilateral symmetry.
Further, arm 6 is sprayed with spray supervisor 5 in 50-80 ° of angle.
Further, it is provided with at least three layers of spraying layer in described desulfuration spray tower device, be wherein positioned at the spray of bottom two-layer
Drenching layer and arranging upper and lower Bidirectional nozzle, each spraying layer on its top is provided with downward unidirectional nozzle.
The beneficial effects of the utility model are:
(1) diameter of this desulfurization spray equipment spray supervisor is gradually reduced to end from initiating terminal, it is ensured that supervisor's end
Nozzle exit pressure；
(2) the spray arm of this spray equipment is in tilted layout, and can guarantee that the spray arm arranging near spray supervisor's end
Spray coverage rate: it is shorter that traditional vertically disposed spray arm arranges length at Ta Bichu, and be obliquely installed and add spray
Drench the length of arm, more nozzle can be distributed；
(3) the nozzle nonuniform mutation operator of this spray equipment, according to the distribution character of flue gas, on spraying layer, enters away from flue gas
The nozzle quantity at the position of mouth is more than the nozzle quantity near smoke inlet position；Can be when desulfurizing tower runs, it is ensured that every layer of spray
In desulfuration spray tower 360 ° can be atomized by each nozzle on shower pipe road in all directions simultaneously, can significantly improve spray coverage rate,
Thus reach to improve desulfuration efficiency, it also avoid the waste of slurries simultaneously.
Brief description
Fig. 1 is the front view of the utility model desulfuration spray tower spray equipment.
Fig. 2 is the drawing in side sectional elevation that the utility model desulfuration spray tower spray equipment is positioned at spraying layer position.
In figure, 1. tower body, 2. smoke inlet, 3. spraying layer, 4. exhanst gas outlet, 5. spray supervisor, 6. spray arm, 7. spray
Mouth.
Detailed description of the invention
With specific embodiment, the utility model is further illustrated below in conjunction with the accompanying drawings.
According to the research to prior art for the applicant, when flue gas is by absorption tower entrance, flue gas divides above absorption tower
Cloth is uneven, according to the flowing law of gas in tower body, by CFD simulation discovery: divide away from smoke inlet position on absorption tower
Cloth exhaust gas volumn is more than near smoke inlet position.And the how average arrangement of nozzle of absorption tower spraying layer, cause outside to absorb flue gas
The limestone slurry liquid measure of middle SO2 is superfluous and the slurries at center are not enough.
According to this technical problem, take implementation below:
Seeing Fig. 1-Fig. 2, a kind of desulfuration spray tower spray equipment, including tower body 1, smoke inlet 2, spraying layer 3, flue gas goes out
Mouth 4.
As in figure 2 it is shown, spraying layer 3 includes the spray supervisor 5 of reducing, it is main that one end of multiple spray arms 6 is arranged on spray
On pipe 5, the other end seals the madial wall being fixed on desulfuration spray tower, and the spray arm 6 at spray supervisor 5 two ends is symmetrical arranged.Spray
Drench and be connected with spray arm 6 by flange short tube on supervisor 5, it is simple to install and maintenance.
At least multiple screw type nozzles 7 on each spray arm 6 described, spraying layer is distanced laterally from the spray of smoke inlet
Drench the spiral nozzle quantity at layer position more than the spiral nozzle quantity near smoke inlet position.
Concrete when applying desulfurization spray equipment of the present utility model, the first spray of desulfuration spray tower still according to existing maturation
Drench layer pipeline layout method and calculate three sections of diameters of spray supervisor.
Present embodiment, by rational transformation spraying layer, makes the area coverage of slurries meet flue gas flow field branch and requires,
Ensure every layer of spray coverage rate having abundance, it is ensured that flue gas is sufficiently washed on cross section in tower.
