Background technology
A large amount of consumption of coal and the discharge of combustion product cause serious pollution to China's environment, and the pollution controlling fine particle is the great demand that national energy-saving reduces discharging strategy.China take fossil fuel as main energy sources, and PM2.5 will continue the primary pollutant as China city and regional atmospheric, and air PM2.5 concentration ratio developed country of China high several times, cause serious threat to health and socio-economic development; PM2.5 originates complexity, and it is stationary source and the moving source of main fuel that its source mainly comprises with fossil fuel.In addition, each Heavy Metallic Elements of the usual enrichment of fine particle, larger to the harm of environment, particle has become the outstanding problem of air environmental pollution, day by day causes the great attention of countries in the world.
Chinese patent CN1242830C discloses a kind of coal-fired superfine particulate matters reunion promotion method and device thereof, and the device of this invention comprises fluid reservoir, mixing chamber, air compressor, double-current atomizer, mixing-chamber inlet is connected with fluid reservoir and water for industrial use respectively by pipeline, and mixing chamber outlet, air compressor are connected without talking about nozzle with double fluid by pipeline; The agglomeration promotor flowed out from fluid reservoir is atomized by double-current atomizer by the pressure-air that air compressor produces at mixing chamber and the abundant mixed solution of water for industrial use, and during use, double-current atomizer is placed in the flue before electrostatic precipitator.This apparatus structure is simple, dependable performance; But the tube connector of the double-current atomizer in this device in flue is arranged the impact that is subject to flue gas wind speed in flue and produces and rock, and can not reach the effect that safety is fixing.
Utility model content
The purpose of this utility model overcomes in existing flue to reunite to promote that sprayer unit is subject to flue gas windage in flue and produces the problem of rocking.
For this reason, the utility model provides the reunion of a kind of coal-fired ultrafine grain and promotes device, comprises main pipeline, tube connector, tube connector fixed mount, nozzle and flue; Described main pipeline is arranged on outside flue, tube connector is arranged in flue, described tube connector one end is connected with main pipeline through flue, and tube connector is fixed on flue both sides by tube connector fixed mount, described nozzle is fixed on tube connector, and be communicated with tube connector, the spout of described nozzle is towards flue outlet direction.
As one preferred embodiment, described tube connector has many, and it is all communicated with main pipeline.
Further, described multiple tube connector equidistantly distributes.
As one preferred embodiment, the nozzle on described tube connector has multiple.
Further, the nozzle on described every root tube connector equidistantly arranges.
Further, described nozzle is fixedly connected with by screw and nut pad with between tube connector.
Compared with prior art, the beneficial effects of the utility model:
(1) this coal-fired ultrafine grain that the utility model provides is reunited and is promoted that nozzle is fixed by device, diplomatic corps can assemble solution spray flow field and more even, ensure to reunite preferably spray effect, avoid sprayed into solution to be sprayed onto on horizontal flue inwall, and cause the particle fouling on inwall in flue gas.
(2) this coal-fired ultrafine grain that the utility model provides is reunited and is promoted that apparatus structure is simple, convenient for assembly, be easy to dismounting, manufacturing cost is low, and the coal-fired ultrafine grain being applicable to producing in enormous quantities is reunited and promoted technical process.
Below with reference to accompanying drawing, the utility model is described in further details.
Accompanying drawing explanation
Fig. 1 is the structural representation that the reunion of the utility model coal-fired ultrafine grain promotes device.
Description of reference numerals: 1, main pipeline; 2, tube connector; 3, tube connector fixed mount; 4, nozzle; 5, flue.
Detailed description of the invention
Embodiment 1:
Promote that sprayer unit is subject to flue gas windage in flue and produces the problem of rocking to overcome in existing flue to reunite, present embodiments provide a kind of coal-fired ultrafine grain reunion as shown in Figure 1 and promote device, comprise main pipeline 1, tube connector 2, tube connector fixed mount 3, nozzle 4 and flue 5; Described main pipeline 1 is arranged on outside flue 5, tube connector 2 is arranged in flue 5, described tube connector 2 one end is connected with main pipeline 1 through flue 5, and tube connector 2 is fixed on flue 5 both sides by tube connector fixed mount 3, described nozzle 4 is fixed on tube connector 2, and be communicated with tube connector 2, the spout of described nozzle 4 is towards flue 5 Way out.
This coal-fired ultrafine grain that the utility model provides is reunited and is promoted that device site layout project is before electrostatic precipitator in coal-fired power plant, in back-end ductwork, fix at flue 5 liang of STHs, by tube connector fixed mount, flue 5 two ends are fixed at tube connector 2 two ends, reunion solution enters tube connector 2 through main pipeline 1, again from nozzle 4 ejection after atomization, this structure effectively prevent the interference that the air-flow in flue 5 produces tube connector 2, when ensureing that nozzle 4 normally runs, spray effect will be caused to decline on the impact of tube connector 2 because of air-flow in flue 5.
