Gas and solid powder mixture separator

Abstract

Gas and solid powder mixture separator, which includes a frame, a casing, a mixture separation rotor, a fan and a powder mixture discharge device; the casing is installed on the frame; the mixture separation rotor includes a rotor casing, a sleeve and more than three partitions plate, the inner cavity of the rotor housing is in the shape of a rotating body, and the inner cavity in the shape of a rotating body of the rotor housing is in the shape of a truncated cone, and the radius R1 on the left side of the truncated circular cavity is smaller than the radius R2 on the right; The air inlet position corresponds to the air outlet at the right end of the mixture separation rotor. It has a simple structure and a large processing flow rate; it is suitable for the dust removal of boilers and cement, the separation of rice bran and bran in grain processing, the separation of all gases and solid powder mixtures such as pneumatic conveying, winnowing, air purification and dust removal, and vacuum cleaners.

Description

technical field [0001] The invention relates to a gas and solid mixture separation device, in particular to a gas and solid powder mixture separator. Background technique [0002] At present, the separation methods of gas and solid powder mixture are generally divided into two categories: wet separation method and dry separation method. Dry separation methods are divided into filtration method, cyclone method and electrostatic method. [0003] The filtration separation method has high separation efficiency, can meet strict environmental protection requirements, has stable operation and strong adaptability. However, its disadvantages are large volume, high cost, complicated operation and maintenance, and many auxiliary equipment. Generally, it is used below 270 ° C. The filter material can generally be used for 2 to 3 years. Material selection and production are difficult. [0004] Because there are no moving parts, the cyclone separation method has the advantages of conve...

Problems solved by technology

But its disadvantages are large one-time investment, complex structure, and more steel consumption. Each electric field needs to be equipped with a high-voltage source and control device, which is expensive. When the specific resistance of dust in the flue gas is less than 10 4 Ω·cm or greater than 10 12 Ω·cm, other measures must be adopted to adjust

But its disadvantage is that the discharged muddy sewage must be treated, otherwise it may cause secondary pollution, consume a certain amount of water, cannot be used for hydraulic powder such as cement, and useful dust is difficult to recycle.
