Technical Field

[0001] The utility model relates to the technical field of gas-liquid separation, in particular to a swirl-feed diffuser for a gas-liquid separator. Background Art

[0002] In gas-liquid separation equipment mainly dealing with gas, it is often necessary to make the medium flow state in the separator uniform and stable, reaching an ideal state without turbulent flow, which is beneficial to the sedimentation of liquid droplets so as to achieve the purpose of gas-liquid separation. Therefore, it is necessary to install a diffuser at the inlet of the separator to reduce the kinetic energy at the inlet and evenly distribute the medium in the separator.

[0003] However, the existing diffusers have the following deficiencies:

[0004] 1. High installation accuracy requirements. Otherwise, there will be uneven flow velocity at the diffuser outlet, resulting in poor sedimentation separation effect;

[0005] 2. Complex structure and high manufacturing cost;

[0006] 3. Large size, which increases the size of the separator and thus increases the equipment cost.

[0007] The utility model has made beneficial improvements to overcome the above defects. Content of the Utility Model

[0008] The purpose of the utility model is to solve the above deficiencies in the prior art, and provides a swirl-feed diffuser for a gas-liquid separator, which can preliminarily separate gas and liquid from the gas-liquid medium mainly composed of gas after it enters the gas-liquid separator, and evenly and stably distribute the preliminarily separated gas-liquid medium in the gas-liquid separator through the diffuser, so as to improve the gas-liquid separation effect.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A swirl-feed diffuser for a gas-liquid separator includes a feed inlet and a diffuser box. The feed inlet is arranged at one end of the diffuser box and is communicated with the inlet of the separator. Diffuser elements are installed around the diffuser box. The shape of the diffuser box is conical, cuboid or cylindrical. The gas-liquid mixed medium enters the diffuser box through the feed inlet for preliminary flow stabilization, and then undergoes preliminary separation by the diffuser elements. The diffuser elements are composed of a swirl plate and a diffuser pipe. The swirl plate is a spiral component formed by rotating a certain angle relative to two opposite sides of a quadrilateral. The diffuser pipe is a through pipe with an opening at the bottom. The swirl plate is fixedly installed at the inlet end of the diffuser pipe;

[0011] Further: The diffuser is fixedly connected to the diffuser box, and the inlet end of the diffuser pipe communicates with the interior of the diffuser box. There are multiple diffusers, which are installed side by side on both sides of the diffuser box. The installation quantity of the diffusers can be set according to the flow rate and velocity of the gas-liquid mixed medium.

[0012] Further: The opening at the bottom of the diffuser pipe faces downward, and a liquid accumulation tray is arranged below the multiple diffusers arranged side by side for receiving and collecting the liquid separated from the side opening at the bottom of the diffuser pipe.

[0013] Further: The diffuser is fixedly installed on the diffuser box by welding.

[0014] Further: The liquid accumulation tray is a flat bottom tray with an open upper end, and the upper edge of the liquid accumulation tray is fixedly connected to the diffuser pipe by spot welding.

[0015] Further: A liquid guide pipe is communicated with the bottom of the liquid accumulation tray, and the liquid guide pipe introduces the collected liquid into the liquid phase end in the separator.

[0016] The beneficial effects of the present utility model: In the technical solution of the present utility model, the medium flowing at a high speed at the inlet end of the separator reduces its kinetic energy after passing through the diffuser, and realizes gas-liquid separation, reducing the disturbance to the original medium in the separator, ensuring the uniform and stable flow state of the medium in the separator. Moreover, the structure of the diffuser in the technical solution of the present application is relatively simple, stable, and easy to install. The diffusers are installed in rows in the horizontal direction and can also be installed in multiple layers, making the size of the diffuser assembly smaller, thereby reducing the volume of the separator and lowering the cost.

[0022] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0023] An embodiment of the present utility model is referred to Figures 1-4 As shown, a swirl feed diffuser for a gas-liquid separator includes a feed inlet 1 and a diffuser box 2. The feed inlet 1 is arranged at one end of the diffuser box and is communicated with the inlet of the separator. Diffuser elements 3 are installed around the diffuser box 2. The shape of the diffuser box 2 can be conical, or cubic or cylindrical. The gas-liquid mixed medium enters the diffuser box 2 through the feed inlet 1 for preliminary flow stabilization, and then undergoes preliminary separation through the diffuser elements 3. The diffuser element 3 is composed of a swirl plate 6 and a diffuser pipe 7. The swirl plate 6 is a spiral component formed by rotating a certain angle relative to two opposite sides of a quadrilateral. The diffuser pipe 7 is a through pipe with an opening at the bottom. The swirl plate 6 is fixedly installed at the inlet end of the diffuser pipe 7.

[0024] The diffuser element 3 is fixedly connected to the diffuser box 2 by welding. The inlet end of the diffuser pipe 7 is communicated with the inside of the diffuser box 2. Multiple diffuser elements 3 are provided and are arranged side by side on both sides of the diffuser box 2. The installation quantity of the diffuser element 3 is set according to the flow rate and flow velocity of the gas-liquid mixed medium.

[0025] The medium flowing at high speed enters the diffuser box 2 through the feed inlet 1. After preliminary flow stabilization in the box, it then passes through the diffuser elements 3 uniformly installed around the diffuser box 2. Under the guiding action of the spiral swirl plate 6 at the inlet of the diffuser pipe 7, the medium rotates and flows along the inner wall of the diffuser pipe 7. During the flowing process, due to the circumferential frictional force of the swirl plate and the diffuser pipe, the axial kinetic energy is lower, and within the designed length of the diffuser pipe 7, the kinetic energy at the outlet is reduced to the designed requirement. In this process, the liquid droplets with larger mass are thrown towards the inner wall of the diffuser pipe 7 under the action of centrifugal force and flow out from the opening at the bottom of the diffuser pipe 7, realizing the initial separation of the liquid droplets.

[0026] The opening at the bottom of the diffuser pipe 7 faces downward, and a liquid collecting tray 4 is arranged below the multiple diffuser elements 3 arranged side by side for receiving and collecting the liquid separated from the opening at the bottom of the diffuser pipe 7. The liquid collecting tray 4 is a flat tray with an open upper end. The upper edge of the liquid collecting tray 4 is fixedly connected to the diffuser pipe 7 by spot welding: A liquid guiding pipe 5 is communicated with the bottom of the liquid collecting tray 4, and the liquid guiding pipe 5 introduces the collected liquid into the liquid phase end inside the separator.

[0027] The above-described embodiments only represent one embodiment of the present utility model, but should not be construed as limiting the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
