High-efficiency dust collection cyclone separator group

Abstract

The invention relates to a high-efficiency dust collection cyclone separator group. A plurality of front cyclone separators are in parallel connection, a rear dust hopper is connected to a dust outlet of a rear cyclone separator, a front mounting frame is fixed into a front dust hopper, a front conical funnel cap is fixedly mounted on the front mounting frame, air inlet pipes are parallelly connected onto an air inlet of the rear cyclone separator, the number of the air inlet pipes is matched with that of the front cyclone separators, an air inlet end of each air inlet pipe is arranged insidethe bottom end of a lower conical cylinder of the corresponding front cyclone separator, a rear mounting frame is fixed into the rear dust hopper, and a rear conical funnel cap is fixedly mounted on the rear mounting frame. Secondary entrainment of fine dust at dust discharge ports of the front cyclone separators is eliminated, and the powder content of exhaust gas exhausted through a central pipe in the middle of the rear cyclone separator is greatly decreased. The efficiency of the cyclone separator group can be 3-5% higher than that of a conventional cyclone separator, and the dust collection efficiency of the cyclone separator group is ensured to be higher than 95%.

Description

technical field [0001] The invention relates to a dry dust collection device, in particular to a high-efficiency dust collection cyclone separator group. Background technique [0002] At present, in the field of dry dust collection, cyclone separators are generally used, because cyclone separators have the advantages of simple structure, convenient maintenance, and low cost of use, but the dust collection efficiency of cyclone separators is low. As the primary dust collection equipment, the cyclone separator usually needs to be connected to an electrostatic precipitator or a bag filter at the back end in order to improve the dust collection efficiency. The structure of the electrostatic precipitator and the bag filter is complicated, maintenance is troublesome, and the cost of use is high. In the case of large-flow dust removal, multiple parallel cyclone separators are generally used, which not only has higher dust collection efficiency than a single large-diameter cyclone s...
