Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Such as figure 1 , the present invention proposes a double-throat self-starting supersonic cyclone separator, including a cyclone 1, a Laval nozzle 2 and a diffuser 3.

[0036] Such as figure 2 and image 3 , the cyclone 1 includes a cyclone head 101 , a blade 102 , a nut 103 , a cyclone inner shell 104 , a cyclone shell 105 and a cyclone tail cone 106 . The swirler inner shell 104 is coaxial with the swirler outer shell 105, and placed inside the swirler, and the blades 102 are placed between the swirler outer shell 105 and the swirler inner shell 104, and the blades The number is greater than or equal to 1; the distance between the inner wall of the cyclone shell 105 and the outer wall of the cyclone inner shell 104 is 1 to 50 mm, and the cyclone tail cone 106 is coaxial with the cyclone inner shell 104 , is axially connected to ...

Abstract

The invention provides a double-throat self-starting ultrasonic cyclone separator and a separation method thereof. The double-throat self-starting ultrasonic cyclone separator comprises a cyclone, a Laval spray pipe and a diffusion separator. The diffusion separator is characterized by comprising a separation cone A, a separator shell, a porous wall, a separation cone B and a separation cone C; the wall surface of the porous wall is provided with a plurality of exhaust holes; and an overflow cavity is formed between the outer wall of the porous wall and the inner wall of the separation cone B. According to the separator disclosed by the invention, a porous wall structure is adopted for a contraction section and an expansion section of a diffuser; a pneumatic adjustment action to the circulation area of the throat of the diffuser is played; when upstream pressure fluctuates, self adjustment can be realized; supersonic airflow from the Laval spray pipe is compressed and decelerated in the contraction section of the diffuser, passes through the throat of the diffuser at the speed slightly more than a sound velocity and forms normal shock wave in the expansion section of the diffuser in a condition far below the mach number of the Laval spray pipe; and therefore, the shock loss is low.

Description

technical field [0001] The invention belongs to the technical field of gas removal of condensables, in particular to a double-throat self-starting supersonic cyclone separator and its separation method, which are mainly used in the field of purification and separation of natural gas removal of condensables and gas-liquid separation with phase change field. Background technique [0002] As a clean and efficient energy source, natural gas occupies an increasing share in the world's primary energy consumption market. Natural gas extracted from the ground contains large amounts of water vapour. During the gathering and transportation of natural gas, water vapor is easy to condense into liquid water. Under certain temperature and pressure conditions, liquid water in natural gas will freeze or combine with hydrocarbons to form natural gas hydrate, which will cause blockage of pipelines and their accessories, and reduce natural gas production and pipeline transportation capacity....
