Abstract
The utility model proposes a kind of dry electric precipitation device, comprise cylindrical shell, on described cylindrical shell, be provided with import end socket and outlet end socket; Between described import end socket and described outlet end socket, be provided with electric field, by dedusting operation, at the rear of electric field, be respectively equipped with spray for dust suppression district, ionization dedusting area and dust collection section; Described spray for dust suppression is provided with the water pipe with nozzle in district, and the high voltage source that connects discharge electrode is installed in described ionization dedusting area; In described dust collection section, be provided with dust collection plate.Advantage: this apparatus structure is simple, maintenance workload is low and expense is low, and can remove the dust that is less than 2.5 micron grain sizes.
Description
Technical field
The utility model relates to clarifier, refers to especially a kind of dry electric precipitation device.
Background technology
At present, the difficulty of dry electric precipitation device maximum is: four to five electric fields are originally mainly to remove the meal dirt that is greater than 2.5 micron grain sizes.Its reason is mainly: the dust of 0.2--0.6 micron grain size is neither electric-field charge neither diffusional charging.Its particle diameter is between the two, so its efficiency of dust collection is just lower.Technology adopts the mode of traveling electrode to remove to transform last original electric field now.But expense is very high, and moving component is many, and maintenance workload is large, and can not be completely definite to being less than the removal efficiency of the dust of 2.5 micron grain sizes.
Utility model content
The utility model proposes a kind of dry electric precipitation device, solved the problem that in prior art, machine part is many, expense is high, maintenance workload is large and efficiency of dust collection is low.
The technical solution of the utility model is achieved in that a kind of dry electric precipitation device, comprises cylindrical shell, is provided with import end socket and outlet end socket on described cylindrical shell; Between described import end socket and described outlet end socket, be provided with electric field, by dedusting operation, at the rear of electric field, be respectively equipped with spray for dust suppression district, ionization dedusting area and dust collection section; Described spray for dust suppression is provided with the water pipe with nozzle in district, and the high voltage source that connects discharge electrode is installed in described ionization dedusting area; In described dust collection section, be provided with dust collection plate.
Further preferably, described dust collection plate has polylith, between adjacent dust collection plate, is spaced apart 20-30mm.
Further preferably, between described adjacent dust collection plate, be spaced apart 25mm.
Further preferably, the cross section of described outlet end socket is trapezium structure.
The beneficial effect that the utility model possesses is as follows:
The utility model is provided with two devices of water spray and ionization generator at electric field rear, make electric field above except the fine dust not going and water smoke simultaneously charged, the particle diameter general control of water smoke is in 20-30 micron left and right, just can, by the adsorbing powder dust that is less than 2.5 micron grain sizes on water droplet, by dust collection plate, be collected simultaneously.
In dust collection section, there is polylith dust excluding plate, utilize space charge dust-cleaning principle, on the dust collection plate by the dust collection that is less than 2.5 micron grain sizes in outlet end socket, be removed.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of dry electric precipitation device, comprises cylindrical shell 1.On the rear and front end of cylindrical shell 1, be provided with respectively import end socket 2 and outlet end socket 3.Import end socket 2 is all trapezium structure with the cross section of outlet end socket 3, and electric field has 5 and be arranged on import end socket 2 and export between end socket 3.By dedusting operation, at the rear of electric field, be respectively equipped with spray for dust suppression district 4, ionization dedusting area 5 and dust collection section 6.In spray for dust suppression district 4, be provided with the water pipe 8 with nozzle 11, make electric field above and be adsorbed on water droplet except the fine dust not going, the particle diameter general control of water droplet is in 20-30 micron left and right.Ionization is provided with the high voltage source 9 that connects discharge electrode 10 in dedusting area 5, makes fine dust and water droplet simultaneously charged; Be installed in again and in dust collection section 6, be provided with dust collection plate 7 and collect.
Guarantee to solve the dust problem that is less than 2.5 micron grain sizes.In dust collection section, 6 have interiorly installed polylith dust collection plate 7, and are spaced apart 25mm between dust collection plate 7 and dust collection plate 7.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
