Description
A kind of electrostatic precipitator, particularly a kind of set monoblock type resistive connection reveals high-voltage electrostatic dust separator, belongs to the purifier field to dusty gas.
In the production process of industries such as cement, chemical industry, metallurgy, electric power, can produce great airborne dust.For addressing this problem, generally all adopt deduster dusty gas to be purified and useful dust is reclaimed.At present, the vertical electrostatic precipitator of the employed dry method cylindrical shape of above-mentioned every profession and trade mostly is following two kinds of forms:
A kind of is concentric circles electrostatic precipitator (as shown in Figure 6), is more early stage a kind of.It mainly is to realize that by Electrostatic Absorption and gravitational settling the purification of dusty gas and dust reclaim.Operation principle is: dusty gas enters electric field by blast pipe from the bottom of electric field, under the effect of static straight under the swabbing action of blower fan, dust is attracted on dust collecting pole plate and the corona wire, through dust-collecting and vibrating, dust falls into ash bucket under the gravity effect.
Another kind is a JH-A type electrostatic precipitator, has then adopted cyclonic separation, and Electrostatic Absorption, three kinds of mechanism of gravitational settling are one, have striden forward major step.Its basic functional principle is: dusty gas enters a kind of scroll casing type spiral organ from deduster top, make dusty gas produce the power of rotation at a high speed, be rotated down the electric field bottom at a high speed along the whirlwind tube then, make the dusty gas that rotates at a high speed lose the supporting of cyclone wall, expand suddenly, axially wind speed and warp-wise wind speed produce the zero-speed interface, and thicker dust separation is come out, and fall under gravity into ash bucket; Make the gas that has been lowered initial dust content enter electric field again.
Above-described two kinds of electrostatic precipitator, owing to be subjected to the constraint of operation principle and design feature separately, the corresponding problem that has following deficiency:
1. because the globality of equipment is poor, and the second investment that the user is produced is big, installation and back work amount are big.
Manufacturing firm produces this kind equipment, often has only deduster main body, blower fan, supporting power supply, switch board etc., is to form a set of equipment with the form of parts, and into and out of airduct and joint, blower fan layout etc. is all left user oneself for and implemented.Because the globality of equipment is poor, make the second investment of civil engineering, installation and other ancillary works that the user produces very big.
If use the JH-A220 electrostatic precipitator, though dust-precipitator efficient than concentric circles electrostatic precipitator height, the second investment of leaving the user for is bigger.
Simultaneously, the equipment profile after these two kinds of dedusters are installed is extremely unbecoming.
2. owing to be subjected to the constraint of operation principle and design feature, the specification of deduster and processing Dust Capacity are restricted, and do not satisfy user's actual needs.
The concentric circles electrostatic precipitator, because electric field structure lattice method is simple, the maximum field diameter of section can not surpass Φ 2.25M, otherwise will have a strong impact on dust-collecting efficiency; Simultaneously, auxiliary dust collecting pole plate is laterally to stay spacing, and during rapping, the dust that is adsorbed jumps, and easily produces great secondary fly-up.
JH-A type electrostatic precipitator, electric field and discharge pipe arrange that the cross section maximum gauge can not surpass Φ 2.90M, and the electric field sectional area of JH-A290 has only 5.06, only are equivalent to the area of a circle of Φ 2.54M diameter; The specification of JH-A type has totally five kinds of JH-A170,190,220,260,290, if calculate JH-A320 according to its design feature, the diameter of whirlwind tube equals Φ 1.7M, is equivalent to JH-A170.Obviously, the diameter of whirlwind tube is determined, is not the structure needs of itself, but the needs of electric field structure, because the corona wire discharge must be equidistant.This shows that the diameter of design is big more, the rotary speed of generation is slow more, and the effect that reaches cyclonic separation is more little, and the space of waste is many more, so can only be used for manufacturing and designing of small dimension.
3. supporting power supply can only be located at deduster top, brings a series of trouble to the user.
General cement plant factory building when electrostatic precipitator is installed in reform, if be installed in indoorly, also will expose half outdoor.In addition, supporting power supply is located at the deduster head, three meters square platforms must be arranged, add the cathode rapping device, all need to be equipped with awning, the awning of shelving and being correlated with of the supporting power supply that 350-400Kg is heavy etc., the minimum steel 1-2 ton that will exhaust, if the JH-A220 electrostatic precipitator is installed, the trouble of bringing to the user is more.
The purpose of this utility model, be to provide a kind of supporting power supply is arranged on basic platform one side, the angle of ash bucket is 60 °, but the dust collecting pole plate lattice is 7 lattice, 12 lattice, 19 lattice, satisfy the needs of different size, simultaneously, except that the connection of necessity passes the gusset that shakes, guaranteeing to have under the situation of enough collection ash areas, auxiliary dust collecting pole plate all vertically stays a determining deviation, straight cutting can effectively be controlled the generation of secondary fly-up on earth, because the second investment of the powerful big minimizing user installation of globality of equipment, the set monoblock type resistive connection of good looking appearance reveals high-voltage electrostatic dust separator.
