Description

Technical Field

[0001] This utility model belongs to the field of gas-liquid separation technology, specifically relating to a cyclone-type steam purification device. Background Technology

[0002] With the continuous development of technology, steam, as an important energy and process medium, is widely used in various heating, drying, and distillation processes in modern industrial production. However, during the generation and transportation of steam, some droplets are often entrained, and the presence of these droplets can have many adverse effects on subsequent production processes and equipment. For example, when steam is used for heating, droplets reduce the dryness of the steam, leading to a decrease in heating efficiency; when steam is used to drive a steam turbine, droplets may cause erosion of the turbine blades, affecting the service life and operational reliability of the equipment.

[0003] While some gas-liquid separation devices have been applied to steam purification technologies, most of these devices have shortcomings. For example, some traditional gas-liquid separation devices rely solely on gravity settling or simple baffle separation, which is ineffective at separating fine droplets and cannot meet the requirements of high-precision steam purification. Therefore, existing technologies suffer from low steam purification efficiency and poor separation and purification effects. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a cyclone-type steam purification device, which solves the problems of low steam purification efficiency and poor separation and purification effect in the prior art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A cyclone-type steam purification device, including a separator;

[0007] The separator is shaped like a hollow tank, with an air inlet at the bottom and an air outlet at the top.

[0008] A vertically downward-placed connecting shaft is connected to the top inner surface of the separator. The connecting shaft is placed coaxially with the separator. A spiral first guide plate and a second guide plate are fixed on the peripheral wall of the connecting shaft.

[0009] The first guide plate is fixed to the lower section of the connecting shaft, and the end of the first guide plate away from the central axis of the connecting shaft is in contact with the inner peripheral wall of the separator.

[0010] The second guide plate is fixed to the upper part of the connecting shaft, and the end of the second guide plate away from the central axis of the connecting shaft is in contact with the inner peripheral wall of the separator.

[0011] A filter element assembly is fitted onto the connecting shaft. The filter element assembly is located between the second guide plate and the air outlet. The filter element assembly is made of hydrophobic material and has pores that allow gas to pass through while preventing liquid from penetrating.

[0012] The spiral directions of the first guide vane and the second guide vane are opposite.

[0013] The pitch of the second guide plate is smaller than that of the first guide plate.

[0014] The pitch of the second guide plate gradually increases from the lower end to the upper end.

[0015] The filter element assembly includes multiple filter element layers arranged along the axis of the connecting shaft. There is a gap between each pair of adjacent filter element layers. The air pores of the filter element assembly are opened on the filter element layers, and each filter element layer has multiple air pores.

[0016] The diameter of the pores on each filter layer gradually decreases from the bottom layer to the top layer.

[0017] The central axes of the pores in two adjacent filter layers are misaligned.

[0018] Both the first and second guide plates have guide grooves at their ends away from the central axis of the connecting shaft. The guide grooves are arranged along the first or second guide plate, and the ends of the guide grooves away from the connecting shaft are in contact with the inner peripheral wall of the separator.

[0019] The separator includes a detachably connected tank and a cover, with the upper end of the connecting shaft detachably connected to the cover.

[0020] The filter layers are all detachably connected to the connecting shaft.

[0021] The beneficial effects of this utility model are:

[0022] 1. Through the spiral first and second guide plates, the steam is guided to move along the spiral path during the upward process, and the droplets are thrown towards the inner wall of the separator under the action of centrifugal force, achieving preliminary separation; combined with the interception of the filter element assembly, a dual purification mechanism of "spiral centrifugation + filtration" is formed, which significantly improves the steam purification efficiency.

[0023] By setting the first and second guide plates in opposite spirals, the steam flow direction changes abruptly, and the droplets collide and coalesce due to inertia. At the same time, the centrifugal separation effect is enhanced, the separation efficiency is improved, and the dead angle of the eddy is reduced, ensuring more thorough steam purification.

[0024] 2. By using the differentiated design of the large pitch of the first guide plate and the small pitch of the second guide plate, gradient separation of droplets of different sizes in the steam is achieved. This not only ensures the separation effect, but also avoids excessive pressure drop caused by excessive compression of the pitch. This design enables the steam to achieve a smooth transition from coarse separation to fine separation when passing through the two-stage guide plates, which significantly improves the overall separation efficiency.

[0025] Meanwhile, the gradually changing pitch design of the second guide plate allows the steam to transition more smoothly when passing through it, which not only improves the capture efficiency of small droplets but also ensures the stability of the system operation. Furthermore, the gradually widening pitch structure helps to reduce airflow disturbance and prevents the separated droplets from being entrained again, thereby improving the overall purification effect of the separation device.

[0026] 3. By employing a gradient filtration design with gradually decreasing pore diameter from bottom to top in multiple filter layers, premature clogging of small-pore filter elements is avoided, while efficient classification and interception of droplets of different sizes are achieved. This optimizes airflow distribution while ensuring filtration accuracy, significantly reduces system pressure drop, and extends filter life.

[0027] Furthermore, the central axes of the pores between adjacent filter layers are misaligned, forcing the steam to form a tortuous path when passing through the filter assembly, which prolongs the contact time between the airflow and the filter material and enhances the collision and interception effect of the droplets.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] This combination Figures 1 to 3 This document describes an embodiment of a cyclone-type steam purification device. Specifically, the cyclone-type steam purification device is constructed as a split structure, comprising a separator 100, an inlet 101, an outlet 102, a connecting shaft 200, a first guide plate 300, a second guide plate 400, and a filter element assembly 500. Through the spiral arrangement of the first guide plate 300 and the second guide plate 400, the steam is guided to move along a spiral path during its ascent. Under the action of centrifugal force, the droplets are thrown against the inner wall of the separator 100, achieving preliminary separation. Combined with the interception of the filter element assembly 500, a dual purification mechanism of "spiral centrifugation + filtration" is formed, significantly improving the steam purification efficiency and purification quality.

[0034] Please refer to Figures 1 to 3 A cyclone purification steam device, comprising a separator 100;

[0035] The separator 100 is in the shape of a hollow can, with an air inlet 101 at the lower end and an air outlet 102 at the upper end.

[0036] A vertically downward-placed connecting shaft 200 is connected to the inner top surface of the separator 100. The connecting shaft 200 is placed coaxially with the separator 100. A spiral first guide plate 300 and a second guide plate 400 are fixed on the peripheral wall of the connecting shaft 200.

[0037] The first guide plate 300 is fixed to the lower section of the connecting shaft 200, and the end of the first guide plate 300 away from the central axis of the connecting shaft 200 is in contact with the inner peripheral wall of the separator 100.

[0038] The second guide plate 400 is fixed to the upper part of the connecting shaft 200, and the end of the second guide plate 400 away from the central axis of the connecting shaft 200 is in contact with the inner peripheral wall of the separator 100.

[0039] A filter element assembly 500 is sleeved on the connecting shaft 200. The filter element assembly 500 is located between the second guide plate 400 and the air outlet 102. The filter element assembly 500 is made of hydrophobic material and has air holes 5011. The air holes 5011 are used for gas to pass through and prevent liquid from penetrating.

[0040] The cyclone purification steam device of this application can be used in conjunction with the evaporation kettle in the prior art, in which the liquid boils at the bottom to generate continuously rising steam;

[0041] After steam enters the separator 100 through the inlet 101, it comes into contact with the spiral-shaped first guide plate 300 and second guide plate 400 in sequence. During the upward movement, the steam is guided by the first guide plate 300 or the second guide plate 400 and moves upward along the spiral path. This spiral upward movement causes the liquid droplets in the steam to be thrown towards the inner peripheral wall of the separator 100 under the action of centrifugal force, thereby achieving preliminary gas-liquid separation.

[0042] After the steam reaches the filter element assembly 500, the steam finally passes through the filter element assembly 500 made of hydrophobic material. The pores 5011 on the filter element allow gas to pass through but block liquid. The purified steam is discharged from the outlet 102. The combination of two-stage spiral flow and one-stage filtration effectively improves the purification effect and efficiency of the steam.

[0043] The first guide plate 300 and the second guide plate 400 have opposite spiral directions. In this application, the first guide plate 300 and the second guide plate 400 are arranged with opposite spiral directions. When steam passes through the first guide plate 300 and forms a rotating airflow, it enters the second guide plate 400 and experiences a sudden change in flow direction due to the opposite spiral directions. This reverse arrangement causes the droplets in the steam to collide and aggregate due to inertia when their direction changes, resulting in a stronger centrifugal separation effect. Through two spiral guides in different directions, not only is the droplet separation efficiency improved, but also potential vortex dead zones in the steam flow field are avoided, ensuring the stability and thoroughness of the separation process. Ultimately, after the steam undergoes two stages of spiral separation in different directions, the entrained droplets can be removed more thoroughly, improving the purification efficiency and quality of the steam.

[0044] The pitch of the second guide plate 400 is smaller than that of the first guide plate 300. This differentiated pitch design allows the first guide plate 300 to form a spiral channel with a larger pitch, generating a strong centrifugal force field, mainly used to separate larger droplets in the steam. The second guide plate 400, on the other hand, uses a spiral channel with a smaller pitch, forming a denser rotating flow field, which can more effectively capture the fine droplets remaining in the steam. Through this pitch change from large to small, gradient separation of droplets of different sizes in the steam is achieved, ensuring the separation effect while avoiding excessive pressure drop caused by excessive pitch compression. This design allows the steam to achieve a smooth transition from coarse to fine separation when passing through the two-stage guide plates, significantly improving the overall separation efficiency.

[0045] The pitch of the second guide plate 400 gradually increases from the lower end to the upper end. This gradually expanding pitch structure allows the steam to gradually decrease its rotational speed as it rises through the second guide plate 400. Specifically, a stronger centrifugal force field is formed at the lower end where the pitch is smaller, which can effectively separate smaller droplets. At the upper end where the pitch is larger, the airflow rotational speed slows down, ensuring separation efficiency while avoiding excessive pressure drop loss. This gradually changing pitch design allows the steam to achieve a smoother transition when passing through the second guide plate 400, improving the capture efficiency of small droplets and ensuring the stability of system operation. At the same time, the gradually expanding pitch structure also helps to reduce airflow disturbance and prevent the separated droplets from being re-entrained, thereby improving the overall purification effect of the separation device.

[0046] The filter element assembly 500 includes multiple filter element layers 501 arranged along the axis of the connecting shaft 200. A gap is left between each pair of adjacent filter element layers 501. The filter element assembly 500 has pores 5011 on the filter element layers 501. Each filter element layer 501 has multiple pores 5011. The multiple pores 5011 on each filter element layer 501 form a three-dimensional filtration network to effectively filter residual droplets. This layered filtration structure not only improves the filtration accuracy but also extends the service life of the filter element. At the same time, the gap design ensures the uniformity of airflow distribution and keeps the overall filtration pressure drop stable.

[0047] The diameter of the pores 5011 on each filter layer 501 gradually decreases from the bottom to the top. The filter element assembly 500 adopts a gradient filtration design with the diameter of the pores 5011 gradually decreasing from bottom to top, so that the steam passes through three stages of coarse filtration, medium filtration and fine filtration in sequence during the upward flow of steam. The larger pores 5011 in the lower layer first intercept the larger droplets carried in the steam, the pores 5011 in the middle layer further filter medium-sized droplets, and the fine pores 5011 in the upper layer finally ensure the complete removal of tiny droplets. This progressive filtration structure not only avoids premature clogging of the small-pore filter element, but also achieves efficient graded interception of droplets of different sizes. While ensuring filtration accuracy, it optimizes the airflow distribution, significantly reduces the system pressure drop, and extends the service life of the filter element.

[0048] The central axes of the pores 5011 of two adjacent filter layers 501 are staggered. The staggered structure forces the steam to form a tortuous path when passing through the filter assembly 500, which prolongs the contact time between the airflow and the filter material and enhances the collision and interception effect of the droplets. At the same time, the staggered arrangement avoids the local high-speed zone caused by the direct airflow, making the filtration pressure drop distribution more uniform, which not only improves the separation efficiency, but also prevents the secondary entrainment of the captured droplets.

[0049] Both the first guide plate 300 and the second guide plate 400 have guide grooves 103 at their ends away from the central axis of the connecting shaft 200. The guide grooves 103 are arranged along the first guide plate 300 or the second guide plate 400, and the ends of the guide grooves 103 away from the connecting shaft 200 are in contact with the inner peripheral wall of the separator 100; guiding the liquid accumulated on the inner wall of the separator 100 downwards to be discharged.

[0050] The separator 100 includes a detachably connected tank and a cover, with the upper end of the connecting shaft 200 detachably connected to the cover; this facilitates opening the separator 100 for maintenance and other operations on its internal components.

[0051] Preferably, in this application, the separator 100 adopts a flange-type detachable connection structure. The upper end of the tank body is provided with an annular flange with 8-12 bolt holes, which is fastened to a matching flange at the lower end of the cover body using high-strength bolts. The upper end of the connecting shaft 200 is detachably fixed to the center hole of the cover body via a threaded structure. To ensure sealing performance, a double-seal design is adopted: a 2mm thick polytetrafluoroethylene (PTFE) gasket is placed between the flange faces as the main seal, while a 200℃-resistant fluororubber O-ring is installed at the mating point between the connecting shaft 200 and the cover body as an auxiliary seal. This structure ensures reliable sealing during equipment operation and allows for quick disassembly and maintenance, significantly improving operational convenience.

[0052] Preferably, the upper end of the connecting shaft 200 is provided with threaded teeth, and the cover is provided with threaded grooves, so that the connecting shaft 200 and the cover are threadedly connected.

[0053] The filter element layer 501 is detachably connected to the connecting shaft 200 to facilitate the maintenance and replacement of the filter element layer 501.

[0054] Preferably, an annular magnet is embedded in the outer peripheral wall of the connecting shaft 200, and a matching ring sleeve is fixedly sleeved on the filter layer 501. The ring sleeve is made of ferromagnetic material and is magnetically connected to the annular magnet.

[0055] Preferably, the filter layer 501 and the connecting shaft 200 can also be detachably connected by a threaded connection.
