As a further technical scheme, the dust removal box comprises a dust removal box at the upper part and a dust falling box at the lower part, the filter bag and the dust removal pipe are positioned in the dust removal box, and the side wall of the dust removal box is kept sealed by the flower plate.
As a further technical scheme, the side wall of the dust falling box is provided with an air inlet, the side wall of the dust removing box at the other side opposite to the air inlet is provided with an air outlet, and the air outlet is positioned above the pattern plate.
As a further technical scheme, the dust falling box is of a conical structure, the small-diameter end is located at the bottom, and the gas distribution plate is arranged inside the dust falling box and is obliquely arranged along the direction of the gas inlet and the dust removing box.
As a further technical scheme, the gas distribution plate is a straight plate or an arc-shaped plate, the arc-shaped plate is bent towards the lateral upper side, and the top of the gas distribution plate points to the position between the adjacent filter bags.
As described in the background art, the existing filter bag dust cleaning method is that the dust is blown inwards by utilizing the position of an air pipe towards the mouth of a filter bag, and the pulse dust cleaning airflow is impacted and vibrated from the inside of the filter bag to the outer surface of the filter bag, so that the purpose of cleaning the outer surface of the filter bag is achieved.
The utility model relates to a sack cleaner ash removal device, including filter bag 6 and deashing pipe 4, wherein deashing pipe 4 sets up the position between adjacent filter bag 6, and the aim at who sets up like this blows in the air current to adjacent filter bag 6 through the deashing pipe, and pulse air current makes the dust direct contact of pulse air current and 6 lateral surfaces of filter bag from the external contact of filter bag 6, makes more thoroughly that the dust was clear away to oily impurity, through pulse air current's effect, more thoroughly that can clear away.
The dust cleaning hole 5 is provided with a hollow truncated cone-shaped structure with two open ends, and the large-diameter end opening is positioned at one side close to the filter bag 6. The ash cleaning hole with the cone frustum-shaped structure can improve the blowing area.
The included angle between the generatrix of the hollow cone and the radial direction of the cross section of the ash removal pipe is 10-60 degrees. Too big contained angle can reduce the speed of sweeping, and too little contained angle can reduce the area of sweeping, and both kinds of circumstances can lead to the deashing effect not good.
2-15 ash cleaning holes are arranged in the longitudinal direction of the ash cleaning pipe 4. The specific quantity is determined according to the length of the filter bag, the blowing area can be reduced when the quantity of the ash cleaning holes is too small, so that incomplete ash cleaning is caused, the blowing speed of the pulse airflow can be reduced when the quantity of the ash cleaning holes is too large, and meanwhile, the energy consumption of the air compressor can be increased.
The distance between the central axis of the dust removing pipe 4 and the outer edge of the filter bag is 1/7 which is larger than the diameter of the filter bag and 1/4 which is smaller than the diameter of the filter bag 6. Too large distance results in too small blowing force and too small blowing area, which results in poor ash cleaning effect.
The device also comprises an air bag 1 and a guide pipe 2, wherein the air bag 1 is connected with the guide pipe 2, and the guide pipe 2 is connected with one end of an air inlet of the ash removal pipe 4. The gas bag provides compressed gas to the conduit, which then provides compressed gas to the ash removal pipe.
The conduit 2 is of a reducing structure, and the diameter of the conduit 2 is reduced by one step at intervals of one filter bag 6 along the flowing direction of the air flow. Every through an ash removal pipe 4 after, the diameter of pipe 2 diminishes a bit, this is because every through an ash removal pipe 4 after, follow-up required compressed air volume is corresponding to diminish, and the ash removal pipe 4 diameter diminishes can guarantee that the gas velocity of flow gets into all ash removal pipes unanimously, and then guarantees that the intraductal pulse tolerance of each ash removal is the same, makes the deashing effect better.
The filter bags 6 are provided in a plurality, and the filter bags 6 are arranged in rows or arrays. As shown in fig. 1, the duct 2 delivers gas from one end of the row of filter bags or it may deliver gas from the middle of the row of filter bags 6. If the filter bags are in a circular array or a square array, the gas can be conveyed from the center of a circle if the filter bags are in the circular array, and the gas can be taken as the starting point of conveying from one end of the filter bags in a row if the filter bags are in the square array.
The filter bag is characterized by further comprising a flower plate 3, and one ends of air outlets of the filter bags 6 are respectively connected with the flower plate 3. The card 3 serves to fix the filter bag 6. The card is flexible construction, when deashing pipe 4 carries out the pulse, can produce decurrent impulsive force to card 3, and flexible construction's card 3 can vibrate under the atress, and then drives the vibration of filter bag 6, can further increase the deashing effect.
The dust removing device further comprises a dust removing box 50, wherein the dust removing box 50 comprises a dust removing box at the upper part and a dust falling box at the lower part, the filter bag and the dust removing pipe are located in the dust removing box, and the side wall of the dust removing box is kept sealed by the pattern plate 3. The dust removed in the dust removing box falls into the dust falling box.
The side wall of the dust falling box is provided with an air inlet 20, the side wall of the dust removing box at the other side opposite to the air inlet 20 is provided with an air outlet, and the air outlet is positioned above the pattern plate. The air flow enters from the air inlet of the dust falling box, passes through the filter bag and is then discharged from the air outlet of the dust removing box, and the dust and oily impurities are blocked outside the filter bag. The dust cleaning pipe is started to clean impurities on the outer surface of the filter bag.
The dust falling box is of a conical structure, the small-diameter end is located at the bottom, and the gas distribution plate is arranged inside the dust falling box and is obliquely arranged along the direction of the gas inlet and the dust removing box. Gas enters from one side of the dust falling box, flows upwards along the gas distribution plate and then passes through the filter bag, so that the dust falling box plays a role in gas distribution, and the gas distribution plate is arranged, so that the gas can uniformly reach the position of each filter bag.
The gas distribution plate 40 is a straight plate or an arc-shaped plate, and the arc-shaped plate is bent towards the lateral upper side. The gas distribution plates 40 are provided in the same number as the number of positions of the gaps between the adjacent filter bags 6. The gas distribution plate 40 can flow uniformly to the flue gas, and prevent the uneven airflow of the dusty flue gas entering the box body, thereby causing poor filtering effect.
The working process of the dust remover is as follows:
dusty flue gas passes through air inlet 20 and gets into the dust remover, then carries out the equipartition to the air current through gas distribution plate 40, and gas after the equipartition continues to upwards move, through filter bag 6, and filter bag 6 filters the dust particle in the flue gas to the surface of filter bag, and clean gas gets into the upper portion of dust removal case after passing through filter bag 6 to discharge through the gas outlet, and the adhesion carries out the deashing through the sack cleaner deashing structure at the dust particle of filter bag surface, and the dust falls into the dust removal case of dust removal case below.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
