Description

Cement in vertical kiln water smoke high-pressure electrostatic complex dust collector

Technical field:

The utility model relates to fume emission dedusting technology field, and specifically, it is a kind of cement in vertical kiln water smoke high-pressure electrostatic complex dust collector.

Background technology:

Industrial dedusting equipment of a great variety has electrostatic precipitator, picogram dragon deduster, sack cleaner or the like.At present, in cement in vertical kiln soot emissions dust collecting process process, the dedusting major part is realized by electrostatic precipitator, big sack cleaner or mist dust remover.In production practices, it is found that above-mentioned several cleaner because dedusting method is single, except that operating cost was higher, its dust removing effects neither be very good.Poor as the electrostatic precipitator dust removing effects, the nitrogen sulfide in the flue gas of shaft kiln can't be discharged, and air pollution is serious; Big sack cleaner operating cost costliness; Mist dust remover not only dust removing effects is poor, and service life is shorter.

Summary of the invention:

The purpose of this utility model is exactly to solve the deficiency that above-mentioned several flue gas of vertical cement kiln discharging cleaners exist, and provides that a kind of dust removing effects is good, long service life and the relatively low cement in vertical kiln water smoke high-pressure electrostatic complex dust collector of operating cost.

The purpose of this utility model is to realize like this, cement in vertical kiln water smoke high-pressure electrostatic complex dust collector comprises body, the anode assembly, the negative electrode assembly, last spray head, following spray head, Air Heater and sewage sump, on the body (11), under be respectively equipped with into, air outlet (1) and (9), the moon is equipped with on top, anode connection insulator (17) and (18), it is characterized in that: in body (11), anode suspension bracket (6) is equipped with on top, negative electrode suspension bracket (7) and spray head (8) on several, several anode metal pipes (5) and several corona wires (4) are installed in respectively on anode suspension bracket (6) and the negative electrode suspension bracket (7), and by lead and wiring insulator (17), (18) link to each other with high-voltage DC power supply, several Air Heater (2) is equipped with in the bottom, spray head (3) is installed in the top of Air Heater (2) under several, on, following spray head (8) links to each other with water pump (12) by feed pipe (10) with (3), body (11) is provided with sewage draining exit (14), sewage draining exit (14) is connected inside and is equipped with on the sewage sump of agitator (13) (15), and the front portion of sewage sump (15) is provided with discharge nozzle (16).

Compared with prior art, the utility model has the advantages that: collection water mist, electrostatic precipitation are one, not only dedusting, denitrogenate the effective of sulfide, and operating cost is cheap, long service life, and dust collection rate can reach more than 99.8%; Save tens kilowatts of required power consumption of depression dust-removing air-introduced machine, thereby saved the energy of a large amount of preciousnesses; Wet dedusting can not cause secondary pollution, and the mud slurry that produces in the dust removal process can promptly solve the blowdown problem of environment pollution caused again as the raw material recycling, has saved raw materials for production again.

Description of drawings:

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is a left view of the present utility model.

The specific embodiment:

Body 11 of the present utility model can adopt the steel plate manufacturing, and inside and outside work gets final product with antirust processing; Anode 5 adopts metal pipe material to make, and the distance of diameter between 19 millimeter, tube and tube is benefit in 12 millimeter; Corona wire 4 adopts conductor wires, and diameter gets final product in 5 millimeter, and the bottom is connected one with identical conductor, constitutes an assembly; Anode 5 and corona wire 4 usefulness insulating materials are installed on anode suspension bracket 6 and the negative electrode suspension bracket 7; Anode suspension bracket 6 and negative electrode suspension bracket 7 also can weld or be fixed by bolts on the inwall of body 1; Anode 5, corona wire 4, anode suspension bracket 6 and negative electrode suspension bracket 7 should adopt the stainless steel manufacturing; Air Heater 2 can adopt down " V " font structure, and its material also can adopt stainless steel or rigid plastics, is installed in bolt on the inwall of body 11; Upper and lower spray head 8 and 3 is connected on the feed pipe that is fixed on body 11 inwalls, and vaporific for guaranteeing that water forms, spout should be less than normal.Anode 5, Air Heater, Air Heater 2 and up and down the number of spray head 8,3 can decide according to the size of deduster cross section; The radical of corona wire 4 is corresponding with the number of anode 5.Agitator 13 can adopt twayblade, the contrary screw feeder that revolves.For ease of maintenance, body 11 should have closed detecting gate; When volume was big, body 11 outer ancient piece of jade, round, flat and with a hole in its centres can be installed ladder stand.

During work, dusty gas enters body 11 from air inlet 1, owing to be subjected to the effect of homogenating plate 2 resistances earlier, flue dust evenly distributes on body cross-section, and after spray head 3 sprayed down, thick soot dust granule landed with water smoke, carries out elementary dedusting; The flue dust air-flow continues to rise, when arriving two high-voltage electrostatic fields that constitute by anode metal pipe 5 and corona wire 4, flue dust is subjected to the effect generation ionization of electric field force, produce a large amount of electronics and ion, the smoke particle that has a negative electricity becomes to combining in positive pole and is adsorbed on anodal 5, the smoke particle that has positive electricity is adsorbed on the corona wire 4, after grit deposits to certain thickness, control system is closed high voltage source, and spray head 8 ejection water smokes are opened in control, the tiny smoke particle that dries up on corona wire 4 and anode metal pipe 5 is washed down, and the gas of purification is discharged from air outlet 1.Close again and close spray head 8, carry out next working cycles.Mud slurry is discharged from sewage draining exit 14, enter sewage sump 15 after, stir, prevent precipitation through agitator 13, flow out from discharge nozzle 16 and reclaim again, calcine, as prepared using.The mud slurry also can flow in other containers through sewage draining exit 14.
