Gas and solid mixture separation method and solid material collection apparatus

Abstract

The invention relates to the gas and solid mixture separation field, and especially relates to a gas and solid mixture separation method and a solid material collection apparatus. The gas and solid mixture separation method is suitable for the large-scale continuous production, and has a general adaptability to materials; and the solid material collection apparatus has the characteristics of small volume, small pressure loss and high separation efficiency. The solid material collection apparatus comprises a separation cylinder (10), a gas and solid material inlet (30), a gas outlet (50) and an air seal machine outlet (40). The gas and solid mixture separation method has a large throughput, reduces the pressure los, and has a better separating effect than a settling chamber during the separation of small-size solid materials. The solid material collection apparatus of a gas-solid mixture has the advantages of simple structure, small volume, small pressure loss and high separation efficiency.

Description

technical field [0001] The invention relates to the field of separation of gas-solid mixture materials, in particular to a method for separating gas-solid mixture materials and a solid material collection device. Background technique [0002] At present, two methods are widely used in the collection of solid materials in drying production. They are the sedimentation method, that is, the speed of the airflow in the sedimentation chamber is suddenly reduced, and the material is collected by the gravity of the dried material itself. The device for collecting materials is called a settling chamber. The disadvantage of this device is that it is huge in size and the collection effect on powdery materials is not good; another typical solid material collection method is the cyclone separation method, that is, by forming an external free vortex in the device. And the internal forced vortex, the material is collected by the action of centrifugal force. The device that uses the cyclone...

[0002] At present, two methods are widely used in the collection of solid materials in drying production. They are the sedimentation method, that is, the speed of the airflow in the sedimentation chamber is suddenly reduced, and the material is collected by the gravity of the dried material itself. The device for collecting materials is called a settling chamber. The disadvantage of this device is that it is huge in size and the collection effect on powdery materials is not good; another typical solid material collection method is the cyclone separation method, that is, by forming an external free vortex in the device. And the internal forced vortex, the material is collected by the action of centrifugal force. The device that uses the cyclone separation method to collect solid materials is the cyclone separator. The volume of the cyclone separator is small, and it can separate fine powder materials, but the cyclone separation The pressure loss of the device is very large, especially when there are fine powdery materials in the materials to be separated, the pressure loss is even greater
