Description
Technical field
The invention belongs to environmental technology field, relate in particular to a kind of electrocoagulation spraying and dust-removing system.
Background technology
At present, the domestic improvement for PM2.5 dust granules in coal-fired flue-gas, rely on the equipment such as electrostatic precipitator, sack cleaner or electric-bag complex dust collector mostly.In electrostatic precipitation, by the strong electric field ionization effect, bulky grain adheres to free electron and removes after charged, but, because PM2.5 is in charged and diffusional charging mixed zone on the scene, charged poor ability, be difficult to remove; Bag-type dusting has removal effect preferably to fine particle, but the bag-type dusting deashing is frequent, reduces the service life of filter bag, and has increased the management difficulty of stable operation; The subject matter that electric-bag complex dust collector exists in the time of solving preferably independent use electric cleaner or sack cleaner.But existing electric-bag complex dust collector is still not high enough to the removal efficiency of fine particle, be difficult to meet the efficient technical need of controlling, as need be, for fine particle, needed the coated filter material that adopts price high.
Summary of the invention
The object of the present invention is to provide a kind of electrocoagulation spraying and dust-removing system, it has the advantages that efficiency is high, cost is low, with fine particles such as PM2.5 in coal-fired flue-gas in the solution prior art, processes the problem existed.
For reaching this purpose, the present invention by the following technical solutions:
A kind of electrocoagulation spraying and dust-removing system, it comprises tower body, wherein, the bottom of described tower body is connected with air inlet pipe, top corresponding to tower body is connected with blast pipe, alternating electric field electricity coalescer is installed on described air inlet pipe, electrostatic field high-pressure dust-cleaning device is installed in the top of air inlet pipe in described tower body, the top of described electrostatic field high-pressure dust-cleaning device is equipped with a plurality of spray heads, described spray head is connected with the absorption liquid pipeline, valve is set on described absorption liquid pipeline and connects the absorption liquid delivery pump, described absorption liquid delivery pump connects absorption liquid dosing pond by pipeline, the top of described spray head is equipped with demister, the bottom of described tower body offers liquid outlet.
Especially, described tower body is divided into cylindrical section and conical section, and described conical section is arranged at the below of cylindrical section, and described air inlet pipe is connected on cylindrical section, and described liquid outlet is opened in the bottom of conical section.
Especially, be provided with deflector in described tower body between demister and spray head.
Especially, the below of described tower body is provided with sedimentation basin, and the bottom of described sedimentation basin is connected with blow-off pipe, and the top of described sedimentation basin connects circulation line and be connected with described absorption liquid dosing pond, on described circulation line, is provided with circulating pump.
Beneficial effect of the present invention is that compared with prior art described electrocoagulation spraying and dust-removing system carries out coagulation also by alternating electric field electricity coalescer to the import flue gas, does not change the physical dimension of existing flue gas ash removal; Can well the PM2.5 fine grained in flue gas be carried out to coalescence coalescent, form the bulky grain thing, more easily be removed by cleaner; Electrostatic field high-pressure dust-cleaning device can directly apply in wet desulphurization equipment, does not change the physical dimension of wet desulphurization; Under the ionization of electrostatic field, particle can fully ionize, and is adsorbed in the both sides pole plate, and capturing efficiency is high; Absorption liquid adopts alkaline absorption solution, can directly wash away the particle that pole plate goes out to adhere to, and prevents that the secondary of particle from escaping; There is good dedusting effect, the advantage that cost is low.
The accompanying drawing explanation
Fig. 1 is the structural representation of the electrocoagulation spraying and dust-removing system that provides of the specific embodiment of the invention 1.
The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
Refer to shown in Fig. 1, Fig. 1 is the structural representation of the electrocoagulation spraying and dust-removing system that provides of the specific embodiment of the invention 1.
In the present embodiment, a kind of electrocoagulation spraying and dust-removing system comprises tower body 1, described tower body 1 is divided into cylindrical section and conical section, described conical section is arranged at the below of cylindrical section, the bottom of described cylindrical section is connected with air inlet pipe 2, top corresponding to described cylindrical section is connected with blast pipe 3, the bottom of described conical section offers liquid outlet 4, alternating electric field electricity coalescer 5 is installed on described air inlet pipe 2, electrostatic field high-pressure dust-cleaning device 6 is installed in the top of air inlet pipe 2 in the cylindrical section of described tower body 1, the top of described electrostatic field high-pressure dust-cleaning device 6 is equipped with a plurality of spray heads 7, described spray head 7 is connected with absorption liquid pipeline 8, valve 9 is set on described absorption liquid pipeline 8 and connects absorption liquid delivery pump 10, described absorption liquid delivery pump 10 connects absorption liquid dosing pond 11 by pipeline, the top of described spray head 7 is equipped with deflector 12, demister 13 is installed in the top of described deflector 12.
The below of described tower body 1 is provided with sedimentation basin 14, and the bottom of described sedimentation basin 14 is connected with blow-off pipe 15, and the top of described sedimentation basin 14 connects circulation line 16 and be connected with described absorption liquid dosing pond 11, on described circulation line 16, is provided with circulating pump 17.
