Embodiment Construction

[0017] Referring to Figures 1 to 7, the present invention consists of a first-stage cyclone A and a second-stage cyclone B, and a second-stage cyclone is connected on the same axis as the lower end of the first-stage cyclone A. Device B. in:

[0018] The first-stage cyclone A includes a feed chamber 1, an overflow pipe 3, a cylinder 4, and a cone 5. The feed chamber 1 is connected to the upper end of the cylinder 4, and the lower end of the cylinder 4 is connected to the upper end of the cone 5. The overflow pipe 3 coaxially penetrates the upper end of the feed chamber 1 into the barrel 4.

[0019] The second-stage cyclone B includes a secondary guide 7, a secondary overflow pipe 8, a secondary cylinder 9, a secondary cone 10 and a bottom flow pipe 6, and the upper end of the secondary cylinder 9 is connected to the first-stage cyclone The lower end of the cone 5 is connected with a small opening, the secondary guide 7 is installed in the upper end of the secondary cylinder ...

Abstract

The present invention discloses one kind of cascade cyclonic separator, and belongs to the field of liquid-solid and liquid-liquid separating apparatus. The cascade cyclonic separator consists of two serially connected cyclonic separator units, each of which consists of feeding cavity, guider, overflow pipe, barrel, cone, underflow pipe and other parts. The second cyclonic separator unit has its guider inlet connected directly to the underflow port of the first one, so that the under flow from the first cyclonic separator unit can enter the second one for secondary separation. The overflow of the second cyclonic separator unit is made to enter the cavity of the first one or led out through one additional pipe. The present invention has the advantages of high separating efficiency, compact structure, low cost, low power consumption and wide use.

Description

technical field [0001] The invention relates to a cascade cyclone separation device, which is suitable for gas-liquid, liquid-liquid, liquid-solid two-phase or multi-phase separation in industries such as petroleum, chemical industry, environmental protection, medicine and food. Background technique [0002] The hydrocyclone has a simple structure and is easy to operate and maintain. It is a kind of equipment widely used in the gas-liquid-solid heterogeneous separation process. In order to improve the separation efficiency, the cyclones are used in series, which are divided into overflow series and underflow series. The structure of the series cyclone system is complicated, and the connecting pipeline increases the resistance loss of the whole system. Especially in places where the layout space is limited, it cannot be used normally. Contents of the invention [0003] The purpose of the present invention is to provide a cascaded cyclone separation device to solve the pro...
