Integrated coaxial recycling serial connection type high-efficiency cyclone separator

Abstract

The invention relates to an integrated coaxial recycling serial connection type high-efficiency cyclone separator which is small in size, short in air flow route, small in pressure drop, stable in air flow field, stable in property and high in separation efficiency. The integrated coaxial recycling serial connection type high-efficiency cyclone separator comprises a main shell, an air inlet tube, an exhaust tube and a discharge cabin. The integrated coaxial recycling serial connection type high-efficiency cyclone separator is structurally characterized in that a backflow device is further arranged on the top of the main shell; the backflow device comprises a backflow tube, a backflow volute and an inner cylinder which is connected with the lower end of the backflow volute; the inner cylinder is coaxially arranged with the main shell and the exhaust tube; the air inlet tube is arranged on the main shell below the backflow device; and the air inlet tube is connected with the main shell so as to form an air inlet volute.

Description

technical field [0001] The invention relates to a cyclone separator used for dust purification and powder particle separation in industrial kilns, metallurgical mines, light industrial building materials, petrochemical industry, garbage cleaning and other industries, especially a coaxial recirculation series high-efficiency cyclone separator. Background technique [0002] At present, dust removal equipment is generally used to control and separate dust and dust. There are several types of dust removal equipment, such as mechanical type, wet type, filter type, and electrostatic type. Compared with other dust removal methods, the mechanical type has the advantages of simple structure, low cost, and easy maintenance. The disadvantage is low efficiency. Since mechanical dust collectors are generally used as primary (primary) dust removal, other methods (such as wet or filter) of secondary dust removal equipment are also required. The cyclone separator is a commonly used mechan...

AI Technical Summary

Problems solved by technology

Compared with other dust removal methods, the mechanical type has the advantages of simple structure, low cost, and easy maintenance. The disadvantage is low efficiency.

This kind of separator has the following disadvantages: 1. The separation diameter is small, generally 10 μm, and the separation efficiency is low, generally 80%-90%. It is almost impossible to separate dust below 5 μm; 2. The amplification effect is large, and the conventional cyclone As the diameter of the separator increases, the separation efficiency decreases rapidly; 3. The fluid shear stress is large and the pressure drop is large; 4. The operation stability is poor and the elasticity is small

Although the double-cycle cyclone separator has a certain dust removal effect, it has the disadvantages of long gas flow path, multiple gas inlet and outlet channels to realize double-cycle separation of dust, and complex structure.
