Problems solved by technology

Among them, the gravity separator can only separate particles with a particle size larger than 50 μm, and the cyclone separator can separate particles larger than 10-20 μm, but the fluctuation of gas volume has a great influence on the separation efficiency

Embodiment Construction

[0024] The present invention will be described in detail below with a typical implementation, but not limited to this implementation.

[0025] see figure 1 , the dynamic cyclone double-stage separator of the present invention mainly consists of an upper body 12, a separator main body 27, a main shaft 18, an upper row of separation pipes 28, a connecting end cover 22, a rotating impeller 3, a bearing bracket 13, an upper bearing 17, and a lower bearing 19. The return pipe 1, the dust collection chamber 2, the upper partition 7, the middle partition 6, the lower partition 6, the sealing packing 10, and the rotary seal 23 and other components.

[0026] Main shaft 18 is supported by upper bearing 17 and lower bearing 19, and bearing is positioned by upper body 12, bearing bracket 13, bearing gland 14 and bearing compression nut 16. The main shaft 18 drives the rotating impeller 3 to generate a centrifugal separation flow field and pressurization. The separator has three nozzles ...

Abstract

The invention provides a dynamic two-stage cyclone separator, aims to effectively integrally treatment of separate purification and supercharging, and provides important means for reducing coal-bed gas gathering and transporting cost, reducing pressure drop and solving coal powder separation difficulty and high gas volume fluctuation. Through structural innovation on the basis of the original dynamic cyclone separator, an inner centrifugal separation flow field is added within an axial distance, a medium mixture can be secondarily separated in the inner centrifugal separation flow field, the content of dust in gas is further reduced, and ultra-purification is achieved. Meanwhile, energy of external drive power is transmitted to a medium through rotation of impeller blades and an upper-row separator pipe, pressure of the medium is increased, and the strict demand of a place on pressure drop is met. In addition, driving speed for maintaining strength of a centrifugal force field never changes with changes in gas volume, so that the dynamic two-stage cyclone separator is highly adaptive to flow fluctuation.

Description

technical field [0001] The invention relates to a dynamic cyclone double-stage separator, which belongs to the technical field of heterogeneous phase separation. Its external power drives its blades and separation tube to rotate, generating a centrifugal force field to separate gas, liquid and phases of different densities. At the same time, the vanes can also pressurize the mixed-phase medium and reduce the pressure drop at the inlet and outlet of the separator. The device is suitable for gas treatment occasions with low pressure, dust, atomized water, and large flow fluctuations, and has a good application prospect in the field of coalbed methane gathering and transportation. Background technique [0002] With the continuous reduction of natural gas resources, the proportion of coalbed methane in energy consumption is gradually increasing. The production, collection and transportation of coalbed methane mostly adopts multi-well and multi-valve group normal-temperature ga...
