The bipolar high-voltage electrostatic coagulator can be arranged on a flue in front of an inlet of an electrostatic precipitator, thereby reducing the content of tiny dust particles in flue gas, improving the collection efficiency of the electrostatic coagulator, and particularly decreasing the discharge amount of PM2.5 dust particles.
Description
Technical field
The utility model relates to a kind of bipolar high-pressure electrostatic knockouts, is suitable for capture industrial fumes or the powdery particle diameter apparatus less than 10 μ m fine particles.
Background technology
Along with the rapid growth of China's economy, society is also increasing substantially to the demand of electric power, iron and steel, cement, and then the smoke contamination thing also increases significantly.Electric cleaner can satisfy the purification requirement of the flue dust of high temperature, high humidity, atm number, and have the pressure loss low, can capture characteristics such as small dust, operating cost are lower, purification efficiency height, be widely used in the field such as dedusting, demist, product recovery of industries such as electric power, iron and steel, building materials, chemical industry.
Along with progressively implementing and the raising of environmental requirement of national energy-saving and emission-reduction policy, further improve cleaner efficient, the discharging of the discharging, particularly fine solid particle of minimizing flue dust becomes the common difficulty that present smoke and dust treatment industry is faced.Because electric cleaner fundamental research in recent years makes little progress, conventional electric cleaner to particle diameter less than 10 μ m, particularly particle diameter obviously reduces less than the grit capture rate of 2.5 μ m, and strainer formula deduster because operating cost height, maintenance difficulties are big, the failure-free operation cycle is short, be unsuitable for high temperature, the high humidity flue dust in controlling etc. shortcoming also be difficult to replace traditional status of electric cleaner at present.
Summary of the invention
In view of electric cleaner fundamental research in recent years makes little progress, for remedying the deficiency of present electric cleaner in the face of fine solid particle, the utility model provides a kind of bipolar high-pressure electrostatic knockouts.Bipolar high-pressure electrostatic knockouts be based on impel fine particle in flue gas cohesion for bulky grain so that the thinking that electric cleaner captures produce.By bipolar high-pressure electrostatic knockouts architectural feature, capture industrial fumes or powdery particle diameter less than 10 μ m fine particles, reduce the content of trickle grit in all types of industries tail gas, the flue gas, so that further improve the means that the dust-collecting efficiency of electric cleaner becomes a kind of necessity.
Technical scheme of the present invention is:
A kind of bipolar high-pressure electrostatic knockouts, one group of positive polarity corona discharge electrode framework constitutes the positive corona utmost point, by insulator support/hang on the knockouts housing, is powered by the positive polarity high-voltage DC power supply; One group of negative polarity corona discharge electrode framework constitutes the negative corona utmost point, by insulator support/hang on the knockouts housing, is powered by the negative polarity high-voltage DC power supply; The ground connection pole plate is arranged between the positive and negative corona discharge electrode, be connected with the knockouts housing, and by the knockouts frame ground, positive polarity corona discharge electrode, earthing pole, negative polarity corona discharge electrode is alternately arranged, constitute the bipolarity charging area; The mixed wind section that is arranged in bipolarity charging area rear portion is equipped with one group by certain regularly arranged dihedral plate, pipe or trough plate.
The utility model has the advantages that:
Constitute positive corona district and the negative corona district that alternately arranges extremely jointly by the positive corona utmost point, earthing pole, negative corona; Ash-laden gas is by the part in positive corona district, the grit lotus that can become positively charged, and by the part in negative corona district, grit can be with negative electrical charge; Become positively charged the grit of lotus and with the grit of going up negative electrical charge after by the bipolarity corona zone of alternately arranging, under the effect of electrostatic force, attract each other and condense and become the bigger grit of particle diameter.Be arranged in mixed wind system behind the bipolarity corona zone and then more can promote the mixing of electropositive grit and elecrtonegativity grit, capture particle diameter less than 10 μ m fine particles, can significantly reduce the discharging of PM2.5 fine particle (being the particle of diameter) less than 2.5um, flue dust or powdered granule dust collection rate have been improved, with this environment of improving the people's livelihood.

Fig. 2 is that Fig. 1 mixes three kinds of element structure schematic diagrames of wind system.
Fig. 3 is the schematic diagram of bipolar high-pressure electrostatic knockouts in electric dust collector.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described again:
As shown in Figure 3, increased bipolar high-pressure electrostatic knockouts in that the electric field (dust collection section) of conventional high-voltage electrostatic dust separator is preceding.Wherein, one group of positive polarity corona discharge electrode framework constitutes the positive corona utmost point 1, by insulator support/hang on the knockouts housing 7, is powered by the positive polarity high-voltage DC power supply; One group of negative polarity corona discharge electrode framework constitutes the negative corona utmost point 2, by insulator support/hang on the knockouts housing 7, is powered by the negative polarity high-voltage DC power supply; The ground connection pole plate is arranged between the positive and negative corona discharge electrode, be connected with knockouts housing 7, and by knockouts housing 7 ground connection, positive polarity corona discharge electrode 1, earthing pole 3, negative polarity corona discharge electrode 2 is alternately arranged, constitute bipolarity charging area 6; The mixed wind section 5 that is arranged in bipolarity charging area 6 rear portions is equipped with one group by certain regularly arranged dihedral plate (seeing Fig. 1, Fig. 2).
Bipolar high-pressure electrostatic knockouts is arranged in (see figure 3) on the preceding flue 9 of electric cleaner 8 inlets, and is very effective to trickle grit content in the minimizing ash-laden gas, can significantly improve the dust-collecting efficiency of electric cleaner, particularly reduces PM
2.5The discharge capacity of micronic dust.Alternately the bipolarity corona zone of arranging is a charging area 6, and entering one section interval of mixing after 5 beginnings of wind section extremely mix the wind section from flue gas is condensation region 4.Because this apparatus arrangement is on the flue of electric cleaner front, wind speed is higher, and corona wire selects that discharge performance is strong for use, rigidity and wearability stainless pin tooth trace preferably.The mixed wind member that mixes wind section 5 has dihedral plate, pipe, three kinds of forms of trough plate, can select for use flexibly according to dust size distribution situation and design wind speed.
