Abstract
The air-equalizing device mounted on the vertical high-voltage electrostatic dust collector is formed from dust-collecting box at lower portion, air-equalizing box at middle portion, dust-collecting electric field at upper portion and adjustable air-equalizing plate mounted in the air-equalizing box.
Description
The utility model relates to a kind of equal wind apparatus that is used for electrostatic precipitator, particularly a kind of equal wind apparatus of vertical electrostatic precipitator.
In the prior art, have only horizontal large-scale electrostatic precipitator to have equal wind problem, promptly the wind speed of each position dusty gas is inhomogeneous in the high-voltage electrostatic field, and causes dust removing effects poor.The solution of taking just becomes vertical homogenating plate porous and hard-wired in the import and export setting of deduster by the punching out of monoblock iron plate.And vertical electric cleaner is generally all thought the small electrical dedusting, does not have the problem of equal wind.Because many advantages such as vertical electric cleaner consumptive material is few, and resistance is little begin to large scale development.Also there is the uneven problem of wind speed in the electric field in the large-scale vertical electric precipitation, can't solve again and causes dust removing effects poor.As use homogenating plate, and needing horizontal positioned, the dust after the dedusting falls the hole of can keeping watch immediately and blocks and can not use.Thereby just do not take any equal wind measure yet.
The purpose of this utility model is to disclose a kind ofly below the vertical electric dust-collecting electric field, loads onto and make that wind speed keeps evenly in the electric field, can keep continuously the adjustable equal wind apparatus of best dust removing effects.
The utility model is realized by following proposal.
It comprises the dust stratification case of the downward convergent of bottom the equal wind apparatus of electrostatic precipitator, the ash discharging hole of dust stratification case bottom and ash discharging hole flange, the air inlet of dust stratification case side and air inlet flange; The equal bellows that communicate with the dust stratification box cavity at middle part; The dust collection electric field that communicates with equal bellows again on top.Be characterized in: the axle that all has a plurality of horizontal shaft holes in the welding of the inboard corresponding both sides of bellows boxboard horizontal fixed indulges in, the axis hole on each corresponding both sides is placed with the non-circular homogenating plate of bearing pin, be installed with the connector rocking bar that has connecting hole that homogenating plate is waved on the homogenating plate one end bearing pin, with the whole homogenating plates of rocking bar aperture rocker pins handle connecting rod that link together and that whole homogenating plates are waved together, one end of connecting rod leaves pin-and-hole and stretches out equal wind box outside, connecting rod links to each other with handle with link pin through pin-and-hole, the lower end of handle is left pin-and-hole and is connected with journal stirrup with handle pin, journal stirrup is weldingly fixed on the equal wind box, adjustment hole is left on handle top, be installed with the adjusting bolt in the adjustment hole, handle is connected with the adjustable plate that leaves the arc strip hole, and adjustable plate is weldingly fixed on the equal wind box.
Advantage and good effect
The equal wind apparatus of a kind of electrostatic precipitator described in the utility model is that can to control adjustable joint turnover.Dusty gas enters equal bellows again after homogenating plate is regulated equal wind, reach optimum state, wind speed enters dust collection electric field equably, gas flow rate, flow, the dust content at each same horizontal plane place in the electric field are all equated, can not take place because of local air flow speed excessively, flue dust has little time the dust removing effects difference appears in charged absorption with regard to entering atmosphere phenomenon.Through test, the gas concentration of emission after dedusting drops to 50mg/m
3Below, less than any pollution is arranged, reached the high standard discharging with soon.Because of equal wind is adjustable, when entering air quantity and change, the angle that can in time regulate homogenating plate still makes its wind speed that is connected into the electric field each several part equate, keeps optimum state.When homogenating plate is long-pending when dust is arranged, move handle, homogenating plate is turned over turn 90 degrees, the plane transfers facade to, and dust falls at once, very easily clears up.
Below in conjunction with embodiment and accompanying drawing in detail the utility model is described in detail.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the cutaway view of A-A among Fig. 1.
In Fig. 1 is embodiment illustrated in fig. 2, the equal wind apparatus of vertical electrostatic precipitator comprises the square dust stratification case 10 of the downward convergent of bottom, the ash discharging hole 12 and the ash discharging hole flange 11 of dust stratification case 10 bottoms, the air inlet 14 of dust stratification case side and air inlet flange 13: the equal bellows 9 that communicate with dust stratification case 10 inner chambers at middle part; The dust collection electric field 21 that communicates with equal bellows 9 again on top is equipped with corona wire 1 and dust collecting pole plate 2 in the dust collection electric field 21.Be characterized in: the axle that all has a plurality of horizontal shaft holes in the bellows 9 inboard corresponding both sides horizontal fixed welding indulges in 7, indulge on 7 at axle and to place the homogenating plate that is shaped as angle steel shape 8 that there is bearing pin 6 at two ends in the every pair of corresponding axis hole in both sides, be installed with on the bearing pin 6 of homogenating plate 8 one ends and can make band that homogenating plate 8 waves connect the rocking bar 5 of pin-and-hole, the connecting rod 3 that whole rocking bar 5 is linked together with rocker pins 4, one end of connecting rod 3 leaves pin-and-hole and is elongated to the outside of equal bellows 9 casings, connecting rod 3 links with link pin 18 and handle 15 through pin-and-hole, the lower end of handle 15 is left pin-and-hole and is linked with handle pin 19 and journal stirrup, journal stirrup 20 is weldingly fixed on equal bellows 9 casings, adjustment hole is left on the top of handle 15, be installed with in the adjustment hole and regulate bolt 17, handle 15 is pulled 16 with the adjusting that leaves the arc strip hole again through adjusting bolt 17 and is linked, and adjustable plate 16 is weldingly fixed on the casing of equal bellows 9.When handle 15 was in the position of I, the gap maximum between each homogenating plate was δ
1, available ventilation area maximum at this moment; Move 45 degree when handle 15, when being in the position of II, the gap minimum between each homogenating plate is δ
2, available ventilation area minimum at this moment; When handle moves 90 when spending, it is maximum that the homogenating plate gap reaches again, at this moment had the plate face of dust stratification to become facade again being in the plane originally, and the dust stratification on it just falls in the ash bucket, reaches the purpose of deashing.Move handle, regulate the angle of homogenating plate, just can regulate the wind speed that enters electric field, reach best dust removing effects.
