Efficient wear-proof drum type cyclone dust collector
A cyclone dust collector and anti-wear technology, which is applied to cyclone devices, devices whose axial directions of cyclones can be reversed, etc., can solve the problem of unreasonable airflow distribution in the pressure distribution chamber, inconvenient manufacturing and installation of spiral cylinders, and cyclone separation. The problem of uneven wear on the side wall of the chamber can improve the safety performance, improve the cyclone effect, and reduce the wear and tear.

Problems solved by technology
[0004] The actual trial found that this kind of dust removal equipment still has some room for improvement: the air distribution in the pressure distribution chamber is not reasonable enough, and the outer wall still has serious wear; The more serious, this is because the lower cone accumulates a large amount of dust, which rotates repeatedly with the airflow, causing repeated wear on the side wall, and the production and installation of the spiral cylinder are not convenient enough
[0005] So far, the dust separation chamber of the cyclone dust collector is single-tube type, and the side wall of the centrifugal separation chamber is inlaid with a wear-resistant lining plate to improve the wear resistance, but it is still inevitably worn or worn out, resulting in a dust removal system. discontinued
The process of the lining board is complicated and the cost is also high.

The invention relates to the technical field of industrial dust removal, in particular to a high-efficiency wear-resistant cylinder type cyclone dust collector, which is suitable for primary dust removal of large-scale equipment such as blast furnaces. The dust collector includes exhaust gas inlet pipe, exhaust pipe, ash collecting hopper, cyclone separation chamber, air distribution chamber, and air flow limiting dust suppressor. Composed of chamber and outer chamber, the side wall of the inner chamber is porous type, and wear-resistant windward blocks are arranged on the side of the hole. The lower part of the outer chamber forms an ash collecting hopper, and the upper part of the cyclone separation chamber is equipped with 6 to 10 straight cyclone square cylinders. air duct. This kind of dust collector has high dust removal efficiency, low dust wear on equipment, smooth flow of air in the dust collector, and good safety performance of the whole dust collector.
Description
technical field [0001] The invention relates to the technical field of industrial dust removal, in particular to a high-efficiency wear-resistant cylinder type cyclone dust collector, which is especially suitable for primary dust removal of large-scale equipment such as blast furnaces. Background technique [0002] There are many kinds of gas dust removal equipment, and cyclone dust removal process equipment is one of them. Blast furnace gas dust removal has high requirements for dust removal equipment, and conventional cyclone dust removal process equipment is difficult to meet the requirements. Invention patent application 0080224l.0 discloses a "blast furnace gas dedusting device", which includes a large cyclone separator with a vertical pressurized tank, the blast furnace gas pipeline from the blast furnace and the axial The conveying device is connected, and the swirl device with guide vanes is arranged under the axial conveying device, so that the blast furnace gas rot...
