Mixed dust separating device

Abstract

PURPOSE: A combination type dust collecting apparatus is provided which maintains high dust collecting performance of the dust collecting apparatus and substantially extends performance and life time of dust collecting filter at the same time. CONSTITUTION: In a combination type dust collecting apparatus in which discharge electrodes(20), collecting electrodes(30) and dust collecting filters(40) are installed inside a main body(10) having inlet(11) and outlet(12), the combination type dust collecting apparatus comprises a splitting plate(50) installed inside the main body between the inlet and outlet; a plurality of mounting holes(51) formed on the splitting plate with being spaced apart from each other in a certain distance; cylindrical dust collecting filters one end of which is insertingly adhered to the mounting holes in a lower part of the splitting plate, and which are horizontally installed in a plurality of rows; a plurality of collecting electrodes which are adhered to the lower surface of the splitting plate at both sides of the dust collecting filters with being spaced apart from each other, and which are arranged slantly and horizontally in a row; a plurality of discharge electrodes which are spaced apart from each other at an outer side of the collecting electrodes and adhered to a mounting ring(60) vertically installed inside the main body in a plurality of rows; guiding portions(70) installed at the lower surface of the splitting plate in front of the collecting electrodes and dust collecting filters corresponding to the inlet; and an outlet installed at one side of the main body in an upper part of the splitting plate.

Description

technical field [0001] The invention relates to a hybrid dust removal device, which includes a dust removal filter, a dust removal electrode and a discharge electrode, and the device can not only function as a filter type dust remover, but also as an electrostatic dust remover, more specifically In other words, the present invention relates to a hybrid type dedusting device which has greatly improved dedusting performance and provides a dedusting filter with much longer operating life and improved performance. Background technique [0002] Generally, places that consume a large amount of combustion gas, such as pulverized coal-fired power plants, use electrostatic precipitators. On the other hand, those places that deal with small or medium quantities of combustion gases or dusty gases use filter-type dust collectors. . [0003] However, as more and more low-sulfur coal is used as fuel, the resistivity of the smoke exhausted by combustion increases gradually. This not only...

Problems solved by technology

However, there is also a problem with the filter-type dust collector: as the dust filtering work progresses, the dust layer trapped on the filter will become thicker and thicker, so the pressure loss of the filter will increase, thus cause the filter not to work properly

However, since the discharge electrode of the electrostatic precipitator generates electric sparks, the dust filter is easily damaged and cannot work normally, so there are also problems.
