Description
Technical field
The utility model is related to flue gas desulfurization and dedusting spray equipments.
Background technology
Major part power source in China's fires the emphasis that electric industry is Air Pollution Control in coal unit power industry at present
Industry.Existing most of coal units remove the sulfur dioxide in flue gas using wet fuel gas desulfurizing technology.Flue gas desulfurization is sprayed
Shower device is one of core equipment the most key in wet fuel gas desulfurizing technology system.Due to the cleaning function of liquid, de-
While except sulfur dioxide, existing conventional flue gas desulfurization sprinkle device can normally only realize the collaboration dedusting of 50%-70%
Efficiency.In September, 2014, National Development and Reform Committee, Chinese Ministry of Environmental Protection, the publication of three ministries and commissions of Bureau of Energy《Coal electricity energy-saving and emission-reduction upgrade takes action with transformation
Plan (2014-2020)》, propose to implement minimum discharge requirement in atmosphere pollution priority control area, i.e., in butt, benchmark oxygen
Under the conditions of content 6%, it is desirable that sulfur dioxide and granular material discharged concentration are respectively no higher than 35mg/Nm3And 5mg/Nm3.This requires
Flue gas desulfurization sprinkle device has higher, more stable desulfurization and dust removal performance.
Existing conventional flue gas desulfurization sprinkle device is largely the spraying layer by being layered setting in desulfuration spray tower tower body
Composition, every layer of spraying layer include that 1~2 spray is responsible for, separates several spray branch pipes from spray supervisor, from spray branch pipe both sides
Separate nozzle.Spray branch pipe is made of wear-resisting glass fibre reinforced plastic.There are two types of spray supervisor is general, one is the resistance to of reducing
Ground glass steel pipe, another kind are the line with rubber carbon steel pipes of not undergauge.Spray supervisor uses the abrasion-resistance glass steel pipe of reducing, due to glass
The elasticity modulus of Steel material is smaller, insufficient rigidity, it is more difficult to while conveying effect and supporting role are taken into account, therefore spray supervisor most
Large span is usually no more than 6 meters.It is more than 6 meters of spray supervisor for length, generally requires by being horizontally fixed on desulfurization spray
Supporting beam in tower tower body is supported, and supporting beam is at a distance from nozzle relatively close to and the appearance and size of supporting beam is generally all
It is larger, it is easy to be washed away by the short distance of sprayed slurry, leads to abrasion, fracture.Spray supervisor uses the line with rubber carbon steel of not undergauge
Pipe, the pressure sprayed in supervisor are gradually reduced along slurries flow direction, cause the grout distribution sprayed out uneven, meanwhile, from
Also easily there is the problem of fouling and clogging in the nozzle that spray supervisor end separates.
Large-sized spray supervisor is (such as：Caliber is more than DN800) it is highly detrimental to being evenly arranged for nozzle, influence spray slurry
The uniformity of liquid covering.If Fig. 1 is existing conventional flue gas desulfurization sprinkle device partial schematic diagram, close to spray supervisor both sides
Nozzle, its spacing H are more much bigger than the spacing h of other nozzles, cause the slurries coverage rate for spraying main pipe area too low, are easy production

Large-sized spray supervisor and quadrate support beam can not only influence the uniformly distributed property of flue gas flow field, and it is de- also to increase flue gas
The flue gas resistance of sulphur spray equipment increases system energy consumption.In addition, spray supervisor is located in desulfuration spray tower tower body, it is not easy to examine
Maintenance is repaiied, safe operation reliability needs to be further increased.
Most of existing conventional flue gas desulfurization sprinkle devices, can generally be staggered two layers adjacent of spraying layer certain water
Straight angle degree, it is that the sprayed slurry of desulfurization tower section is made to cover to enable upper layer nozzle and underlying nozzle staggered positions, main purpose
Evenly, the formation of flue gas escape route is prevented, desulfuration efficiency is improved.If Fig. 2 is a kind of existing conventional flue gas desulfurization sprinkle
The adjacent two layers spraying layer arrangement schematic diagram of device, adjacent two layers spraying layer have been staggered β angles, but that there are some is not complete
The completely wrong nozzle opened, the distance being staggered between adjacent nozzle be also cannot keep it is consistent, it is very uneven, make entire spray-absorption
The sprayed slurry covering in area is not uniform enough, influences desulfurization and efficiency of dust collection.
For this purpose, engineers and technicians disclose a kind of spray equipment for desulfurizing tower, supervisor is arranged outside tower body, tower
Inside be provided with the combination of plural layer branch pipe, the combination of every layer of branch pipe has an arrangement of complex root arms parallel, every layer of same orientation it is parallel
Branch pipe converges outside tower body and is connected with supervisor.This spray equipment is conveniently replaceable maintenance supervisor, reduces cost.But still
There is also some defects：The program requires that 4~6 layers of plural layer branch pipe are arranged in tower, while requiring 5~8 plural numbers of every layer of setting
Root branch pipe, without reference to odd-level branch pipe and every layer of odd number root branch pipe, also without reference to lower 1~3 layer of the setting of cost of investment
Branch pipe assembled scheme；The spray direction for being located at the nozzle above branch pipe is identical as flue gas direction, be easy to cause flue gas and carries spray
Slurries are unfavorable for realizing high-effective dust-removing；The parallel branch pipe in every layer of same orientation converges outside tower body to be connected with supervisor, often
Root be responsible for circulating pump mutually in succession, that is, the branch pipe number of plies be arranged 4 layers when circulating pump quantity need 5~8, invest and
Operation expense is uneconomical.Therefore the program exists in practical engineering application compared with big limitation.
Engineers and technicians also disclose the desulfuration spray tower tower body with Load Regulation and flue gas flow equalizing function, the program
In each layer spray equipment by two be in that arranged crosswise divides spray equipment to form in the same plane.The program thinks to lead to
Stop transport one or the next accurate spray flux for adjusting absorbent slurry of several slurry circulating pumps are crossed, operating cost is reduced.But the program
In spray equipment come with some shortcomings, such as the program merely provides the arrangement of spray tube, adjacent without stressing
Specific location relationship between the nozzle of two layers of spray equipment and arrangement, therefore, it is difficult to ensure that the slurries that nozzle sprays can
Uniformly, the horizontal cross-section of desulfuration spray tower tower body is fully covered.Two are in spray dress in the same plane dividing for arranged crosswise
The branch pipe set is mutually parallel cross arrangement, and the spacing between adjacent branch pipe is 1.5~2m, when stop transport one layer of point of spray equipment after,
Spacing between the adjacent branch pipe of operating status becomes 3~4m, and spacing is excessive, it is difficult to realize to desulfuration spray tower tower body section
Uniformly, complete covering, therefore can not ensure higher desulfurization and dust removing effects.Every layer of spray equipment needs that two slurries are arranged
Circulating pump, cost of investment are uneconomical.
