It should be noted that the third guide plate 103f is provided to a first guide plate 103a-2 inverted semi-circle, i.e., the filter is provided at the top thereof.

[0043] Further, the blower assembly 104 includes a power block to the top of the double-sided rack plate 104a 103e, 104a provided in the power block is electrically connected to a first and a second block 104b above the electrical connection block 104c, and power block 104d is electrically connected to the first connection line 104b, 104e and a high pressure pump connected to the second electrical connection line block 104c.

[0044] Further, the first conducting piece 104b is provided and has a gap length of the other carrying block 104a 104c between the second electrical connection block, the first electrical connection block 104b, a second electrical connection block 104c , the conduction block 104a and a conductive material.

[0045] In use, a pre-dust removal unit 100 is divided into two cycle process. First Process: Referring to figure 1 , The direction of the arrow is defined as the rightward diagram showing the flow direction of flue gas and a flue connected to the smoke flow through hole 102 N, dual combination of a first case 103a and the second plate of the filter bag dual combination plate 103a-3 and 103b are located in the flow of flue gas and both the front and rear flow port disposed through the chimney flue 102 connected to the filter bag 103a-3 is connected to the flue opening of the same size as the through hole 102 of size N. Refer image 3 , The front end and a rear end A filter bag filter bag B in the right direction in the expanded state of the flue gas blowing, the majority of the front end of the filter bag A fly ash in the flue gas is filtered and retained into the receiving space M.

[0046] Second process: As the ash and debris accumulation, the weight of the front end of the filter bag gradually increases, so that the top of the first guide plate dual combination of a first plate 103a 103a-2 is moved downward from the first cleaning member 101 d, and a first dual-use composition of the first rack plate 103a connected to the plate 103a-1 while moving downward rotation of the first gear 103c, 103e causes double-sided rack plate moves upward and the second dual-103d through the second gear combination plate 103b lowered, and finally to the rear end of the front end of the filter bag and filter bag B A completely away at the through port N, fall to the bottom of the housing space 101, with reference to Figure 9 In this case the first guide plate 103a-2, the second guide plate C and the third guide plates 103f rack plate moves under the action of the respective connection to the through hole at the N, C of a second plate a second guide plate dual composition a top portion 103b, which is the same as the structure of the first guide plate 103a-2, at this time, by providing the through hole the same half of the width N of trapezoidal blocks 103a-21 to reduce the flow area through port N flue, the flue gas is changed to the stroke one by one through three sets of screens, which travel a convex shape, an area of ​​increasing its stroke, the flue gas by reducing the flow area and increasing the stroke of the flue gas, the flue gas mixing with the smoke to promote the separation, mixing the flue gas effectively remove dust prevent dust clogging pores denitration catalyst in the reactor, the denitration efficiency improved and denitration effects. Setting a plurality of sets trapezoidal blocks 103a-21 to reduce the flue gas flow area and increases the area of ​​contact with smoke, soot and debris slipping after contacting trapezoidal blocks 103a-21 to the collection tank 105. 103a-3, when moved to the lowest point of the filter bag, carrying block 103e provided at the top of the double-sided rack plate 104a is moved to the highest point of the block and a first electrical contact electrically connected to a second block 104b and 104c is turned on, the high-pressure pump 104e or high-pressure spray gun is energized to work, the front end of the rear end of the filter bag and filter bag B a left inflated at a high pressure gas pump 104e of the impact, the dust in the primary accommodating space pop M, to precipitate the final collection bins. A front end of the filter bag off dust accumulated instant residue left after expansion, to reduce the weight moment, rapid recovery by the spring 103a-4, the high-pressure pump stops 104e off, saving energy. First guide plate when the pick-up or drop 103a-2, the second guide plate C, and a third guide plate 103f are clean 101d, 101e, and 101f of the first cleaning member contacting the third cleaning member and a second cleaning member, prevent the adsorption of dust caused by high temperatures. The rear end of the filter bag B insurance effect, the current end of the filter bag A is damaged, instead of the front end of the rear end of the filter bag filter bag B A similar procedure was repeated to ensure that the pre-adjusted normal dust removing unit 100.

[0047] In summary, by detachably mounted in the conventional denitration reactor dust pre end unit, the flue gas fly ash pretreatment, improve the efficiency of the denitration reactor, ensure the normal operation of the apparatus, and facilitates access to the internet via denitration reactor for maintenance and repair.
