Abstract
The utility model relates to a lampblack purifier comprising a plurality of metal cylinders distributed in parallel and metal ribs distributed on the central axle of all the cylinders, wherein two ends of each metal rib are respectively connected with a front support and a rear support; each metal rib is connected with the cathode of a high-voltage direct-current power supply; and each metal cylinder is connected with the anode of the high-voltage direct-current power supply. When the lampblack purifier works, lampblack enters from the front ends of the metal cylinders, and all the metal ribs are suitable for wholly discharging at the sharp points (the diameter of each metal rib is only 0.5-1mm) and used for ionizing lampblack particles under the actions of the high-voltage direct-current power supply; and meanwhile, an electric field arranged between each metal rib and the inner wall of each metal cylinder is used for absorbing the ionized lampblack particles to the inner wall of each metal cylinder, so that the lampblack is purified. The whole metal ribs discharge at sharp points to ionize the lampblack, so that the lampblack ionization efficiency is high, most of the ionized lampblack particles can be absorbed by the inner walls of the metal cylinders, and furthermore, the lampblack purification efficiency is high.
Description
Technical field
The utility model relates to a kind of cooking fume remover, is applied to the more occasions of oil smoke such as printing and dyeing mill, restaurant.
Background technology
The operation principle of electrostatic oil fume clarifier is to utilize the high-voltage electrostatic field, by the gas ionization between the electrode, makes trickle flue dust and mist of oil colloidal solid charged, thereby it can be adhered on the plate electrode, reaches the purpose that high-efficient oil smoke purifies.
Dual zone type section wire-plate electric field in the electrostatic oil fume clarifier, comprise: the ionized region that is constituted by the line electric field and the adsorption zone (also claiming collecting region) that is constituted by the plate electric field, that is: ionized region is made of the some wolfram steel lines and the positive plate that are connected on the negative plate, between positive and negative pole plate, apply high voltage direct current, particulate in the flue gas is when the ionized region, is ionized electrostatic field ionization that the district forms, makes it to have the plus or minus electric charge; Adsorption zone is made up of some parallel positive and negative pole plates, is applying high voltage direct current (voltage is about half of ionized region) between the positive/negative plate to form electric field, and the positive charge particulate is attracted to collect by negative pole, and the negative electrical charge particulate is attracted to collect by positive plate.Like this, when flue gas passes through collecting region, most charged corpuscle will be removed.Here, air flows provides energy by the blower fan that is positioned at behind the collecting region, promotes air and flows with specific speed.
Chinese patent literature CN101347762B is disclosed in the electrostatic oil fume clarifier.Its weak point is that the gap of many groups of positive and negative pole plates of formation plate electric field is often less, gathers dirt on the positive and negative pole plate easily, causes easily being short-circuited between the plate electric field, causes collecting electric field and loses efficacy, and can't realize the greasy dirt collection; Need to clear up after the regular dismounting, and generally will adopt ultrasonic wave to clean, waste time and energy and cost higher.
Existing another kind of cooking fume remover, as shown in Figure 1, it arranges the metal rib 10 that a straight line distributes in the metal cylinder 3 of parallel distribution, the rear end of each metal rib 10 links to each other with a support 2, the front end of each metal rib 10 is in respectively on the interior central axis of corresponding cylindrical shell, the diameter of each metal rib 10 is 2.5-3.5mm, so that each metal rib 10 has corresponding intensity and remains on the interior central axis of cylindrical shell; Give between each metal rib 10 and the metal cylinder 3 and connect high-voltage DC power supply, oil smoke enters from the front end of each metal cylinder 3, the front end generation point discharge of each metal rib 10, and with smoke particle ionization; Form electric field between the inwall except the remainder of front end and metal cylinder 3 of each metal rib 10, with the adsorbed oil smoke particle.Its weak point is: in actual use, the front end of metal rib 10 can not be on the central axis of cylindrical shell all the time, it is in case exist skew, because the effect of electric field force, the front end of metal rib 10 will speed up to the inwall of cylindrical shell and draws close, finally cause between the inwall of the front end of metal rib 10 and cylindrical shell 3 directly discharge taking place, can't realize smoke particle ionization, and then influence the fume purifying effect.Secondly, because the point discharge major part occurs in the front end (because the thicker cause of its diameter) of each metal rib 10, cause the ratio of smoke particle ionization lower, cause the fume purifying rate lower.
