Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to dust removal equipment for an activated carbon production workshop. Background Art

[0002] Activated carbon is made from carbon-containing raw materials such as wood, coal and petroleum coke through pyrolysis and activation. It is usually a porous amorphous carbon in powder or granular form with strong adsorption capacity. Because a lot of particulate dust is generated in the activated carbon production process and floats in the air, the activated carbon production workshop needs to add dust removal equipment to remove dust from the workshop air.

[0003] Traditional dust removal equipment mainly installs multiple filter bags in the cylinder through a porous plate. The dust-containing gas enters from the lower side of the cylinder, passes through the filter bag, and is conducted upward along the middle of the filter bag. Finally, it is discharged from the air outlet set on the upper side of the cylinder. The dust is isolated by the filter bag and sticks to the outer wall of the filter bag. After a period of use, too much dust adheres to the surface of the filter bag, which will reduce the filtration efficiency. Therefore, the top of the filter bag needs to be connected to the compressed gas bag on the outside through the corresponding blowing pipe. After a period of dust removal, the machine needs to be stopped, and the filter bag is swollen by backblowing through the blowing pipe, and the dust adhering to the filter bag is blown off by wind, and collected and discharged along the ash guide hopper at the bottom of the cylinder. However, since activated carbon itself is a porous amorphous carbon with strong adsorption capacity in powder or granular form, the filter bag needs to be backblown to remove dust after a short period of use, which is very troublesome.

[0004] Therefore, on the basis of ensuring normal dust removal and backblowing dust removal, the purpose of this utility model is to design a dust removal equipment for activated carbon production workshops that can perform preliminary dust removal to reduce the ash content in the air, and then perform dust removal by filter bags, thereby extending the single use time of the filter bags and improving the dust removal efficiency and ease of use.

[0011] The pulse spraying mechanism is used to spray each filter bag.

[0012] The sealing plate, the primary ash hopper and the secondary ash hopper are coaxially arranged.

[0013] The bottom of the filter bag frame extends downward to the upper side of the dust removal cylinder where the air guide pipe is arranged, and the bag opening of the filter bag is sealed and fastened at the connection between the filter bag frame and the embedding hole.

[0020] 1) The dust removal cylinder of the utility model is separated and provided with a dust filtering area and a dust collecting area by a sealing plate, a primary ash hopper and a secondary ash hopper which are fixed in sequence. When the dust-containing gas first passes through the dust collecting area, the dust-containing gas circulation stroke is extended by the ash guide plates arranged staggered up and down, so that part of the dust adheres to the inclined ash guide plates, and a preliminary dust removal treatment is performed to reduce the dust content of the air, and then the dust is filtered and dusted by the filter bag in the dust filtering area, thereby reducing the amount of dust attached to the filter bag per unit time, thereby extending the single use time of the filter bag, effectively reducing the frequency of dust removal equipment shutdown and cleaning, and improving the dust removal efficiency and convenience of use;
