Therefore, the utility model has the advantages of small size, light weight, low cost, high efficiency, energy saving, favorable anti-dewing property, high temperature resistance property and high humidity resistance property, and the utility model is a practical device for industrial flue gas purgation and particularly for treating dust pollution of cement mills.

Description

The efficient composite resistive connection reveals electrostatic precipitator

The utility model is a kind of high voltage electrostatic precipitator, and it is a kind of low cost, high efficiency, the energy-saving electrostatic dust collection equipment that industrial fumes purified, reclaimed useful material, is specially adapted to the elimination of dust contamination in cement plant.

The dust pollution of cement production enterprise is one of rich and influential family of atmosphere pollution, and its features of pollution is many, wide, the spreading of minuteing of point, and its to pollute exhaust gas components complexity, warm height, high humidity, fluctuation range wide, be corrosive, cause the difficulty increasing of improvement.Cement production enterprise is managed objective reality poor, that operating personnel's technical quality is low mostly in addition, cause a large amount of cleaner major parts of cement production enterprise investment over the years normally not move, except that the reason of use aspect, the various cleaners that produce early stage mainly contain following defective and deficiency: the dewfall fault easily takes place in (1), often need to shut down maintenance, this is unallowed in the quantity-produced processing line; (2) dust stratification of dust collector pole inconvenience cleaning after the long-time running is prone to back corona phenomenon, causes dust-collecting efficiency to reduce in time; (3) energy consumption is higher, and operating cost is big; (4) fault rate height, maintenance difficult; In addition, another main cause that this class cleaner can not extensively be promoted is that also equipment cost is higher, and the improvement investment is bigger, and influence is extensively promoted.

The utility model has designed a kind of littler than steel consumption, and cost is low, and is simple and practical, has resistive connection and reveals, and easy-maintaining, cost and other electricity of the operating cost inverse ratio structure of gathering dust reduces 1-2 times energy-saving and high efficient electrostatic precipitator.

For achieving the above object, the utility model is achieved in that (1) adopted bottom vortex type air intake, and the middle part connects the umbrella shape dust collector pole, and the vertical structure of jet air inducing is adopted on top.(2) corona wire upper and lower hung insulator and high pressure inlet wire insulator has all adopted the self-constant temperature anti-dewing insulator.And corona wire can be made single or many cage type corona wires.

Concrete configuration of the present utility model is provided by the following drawings and embodiment:

Fig. 1. the efficient composite resistive connection reveals the electrostatic precipitator structural representation;

Fig. 2. the A-A profile of accompanying drawing 1;

1 flue gas vortex type import among the figure; 2 bottom inspection doors; Pipe in 3 whirlwind; 4 umbrella shape dust collector poles; 5 stainless steel barbed nail corona electrodes; 6 dull and stereotyped vibrators; 7 anti-dewing insulators; Inspection door on 8; 9 spray the air inducing chimney; 10 playpipes; 11 centrifugal blowers; 12 detection platform; 13 dust-precipitator outer cylinder bodies; 14 erection supports; 15 resistance dust hoods; 16 lock wind unloading valves.

In embodiment of the present utility model, by 9,10, the 11 jet air inducing structures of forming, produce enough air inducing negative pressure and air inducing amount, lure that flue dust enters in the dust-precipitator whirlwind from spiral import 1 into and manage 3, at the super-pressure that applies 80-120KV on the stainless steel barbed nail corona electrode on 5, at this moment charged dust is subjected to inertia force, centrifugal force, the compound enhancing effect of electrostatic force, the separated efficient of dust improves greatly, dust is deposited over the inner surface of umbrella shape dust collector pole, when 6 rappings of dust-collecting and vibrating device, shake off outer surface at the next umbrella shape dirt utmost point, the space of enclosing suitable outer cylinder body 13 inwalls of direction along the garden falls into the bottom ash bucket, has avoided colliding the formation reentrainment of dust that disperses with ascending air.The dust of regaining falls into resistance dust hood 15 bottoms, discharges by lock wind unloading valve 16.Flue gas after the dedusting directly is discharged in the atmosphere through spraying air inducing chimney 9.Advantage of the present utility model and effect are as follows:

1. owing to adopted the vertical structure of bottom in and top out, the air inducing resistance of dust-precipitator is very little So the blower fan of operation can be selected the lower model of power consumption; And the employing of anti-dewing insulator Omitted often for solving the additional high-power electric heater of dewfall, the problems such as insulator chamber Also so that the operation the electricity charge can reduce exponentially; If match again the high-efficiency and energy-saving type power supply, Then can reach the relatively low energy saving effect of operating cost.

2. owing to adopt the vortex type air intake, so that centrifugal force, electrostatic force, inertia force are comprehensively done With and the effect that mutually strengthens, and the structure in flue dust shunting makes the effect of gathering dust of equipment Rate improves greatly, and process the comparable common electrostatic precipitator of wind speed and bring up to 1.5-3 doubly, this Just so that same when processing air quantity, the volume of dust-precipitator, steel consumption can reduce at double, in Be, the production cost decrease of equipment, an investment cost of equipment also reduces.

3. because the umbrella structure of dust-precipitator, so that its existing smoke diversion effect can be held concurrently again Make the purposes of inner cat ladder, safeguard and overhaul very simply to reach easily that equipment can the permanent worker Make in efficient state.
