Abstract

The utility model relates to a pre-charging device of an electric duster. The pre-charging device of an electric duster is characterized in that a cathode ray frame is added in front of a third airflow uniform-distribution plate inside a flue gas box, the tops of the cathode ray frame and the third airflow uniform-distribution plate are respectively provided with an electromagnetic rapping system, wherein cathode rays distributed on the frame utilize needle rays and are provided with power supplies separately. After the pre-charging device of an electric precipitator is utilized, dust can be charged before entering a first electric field and can be collected by a front first anode plate and a front second plate. Besides, top electromagnetic rappers arranged on the top portions of both the cathode ray frame and the third airflow uniform-distribution plate can rap to clean dust, which increases dust removing efficiency of the electric duster.

Description

The pre-charged device of electric cleaner

Technical field

The utility model relates to the pre-charged device of a kind of electric cleaner.

Background technology

Observation enters postrun electric cleaner and can find: do not carrying out under the prerequisite of rapping, on the plate face of first and second piece positive plate (length 500mm-1000mm) of first electric field almost is clean, that is to say, first and second piece positive plate of first electric field does not almost play the effect of gathering dust, and makes actual dust-collecting area parameter littler than the area of design.Its reason is the exhaust gas dust of conventional electric cleaner, be after entering electric field, just begin charged, along with flowing forward of flue gas, again with the effect of electric field force, (see figure 1) when charged dust does polar motion, first and second piece positive plate that dust has been crossed first electric field has arrived the middle part of first electric field, and flue gas flow rate is high more, and the piece number of the positive plate that dust is crossed is many more.If dust was powered on regard to lotus before entering first electric field, make it enter electric field and just do polar motion, can improve the efficiency of dust collection of electric cleaner undoubtedly, so the notion of pre-charged dust and technology enter the electric cleaner field.Theoretical and experiment all proves, after installing pre-charged system on the conventional electric cleaner additional, can significantly improve the efficiency of dust collection of electric cleaner.

Summary of the invention

According to above-mentioned thinking, the purpose of this utility model aims to provide the pre-charged device of a kind of electric cleaner.

The purpose of this utility model is achieved in that

The pre-charged device of a kind of electric cleaner, it is characterized in that before inner the 3rd layer of airflow uniform distribution board plane of air inlet smoke box, adding row's cathode line framework, the 3rd layer of airflow uniform distribution plate and cathode line frame roof are respectively equipped with the electromagnetic rapping system, and cathode line is laid on the framework, and sets up power supply separately.

Above-mentioned cathode line adopts the acupuncture line.

Advantage of the present utility model:

Before inner the 3rd layer of airflow uniform distribution board plane of air inlet smoke box, add a row's cathode line framework and a top electromagnetic rapping system thereof, dust was powered on regard to lotus before entering first electric field, collected by last, two positive plates immediately.The dust-collecting efficiency of electric cleaner will obtain bigger raising.

The vibrated system mode that the utility model adopts is the dust on the top electromagnetic rapping removing cathode line, and ash-removal effect is good; Next installs easy-maintaining, and fault rate is low.

The utility model applicability is strong, and applied range is especially limited in the place, or efficiency of dust collection is difficult to adopt in the engineering up to standard this device to prove effective especially.

The specific embodiment

Shown in Fig. 2-3, the pre-charged device of a kind of electric cleaner, before inner the 3rd layer of airflow uniform distribution plate 3 plane of air inlet smoke box, add row's cathode line framework 4, the 3rd layer of airflow uniform distribution plate 3 and cathode line framework 4 tops are respectively equipped with electromagnetic rapping system 5, cathode line 6 is laid on the framework 4, and sets up power supply separately.To the 3rd layer of airflow uniform distribution plate 3 place plane discharge.

When ash-laden gas passes through this electric field region, make dust charged, when charged dust passed through the 3rd layer of airflow uniform distribution plate 3, the part dust was collected by the 3rd layer of airflow uniform distribution plate 3, all the other major parts enter first electric field, can be collected by preceding first positive plate 1, second positive plate 2.The top of cathode line framework 4 and the 3rd layer of airflow uniform distribution plate 3 is equipped with top electromagnetic vibrator 5, regularly carries out dust-collecting and vibrating.

Electromagnetic rapping system 5 is made of electromagnetic vibrator, insulation porcelain connecting rod and insulated leg, interconnects, and is arranged in the thermal insulating case on the air inlet smoke box, isolates (see figure 4) with the dust in the electric cleaner.

The height that other requires according to air inlet smoke box form, flue gas flow rate and efficient, the structural arrangement form of pre-charged system in smoke box can adjust, with assurance dust fully charged before entering electric field (seeing Fig. 5-6), and airflow uniform distribution plate and polar position also can be carried out the adjustment (seeing Fig. 7 a, Fig. 7 b, Fig. 7 c) of position form according to the dust actual conditions.
