Description

Technical Field

[0001] This utility model belongs to the field of boiler combustion, and specifically relates to a multi-stage steam-water separation tower. Background Technology

[0002] Currently, a large amount of steam-water mixture is generated during boiler combustion. In order to obtain dry steam for subsequent production or heating, the steam-water mixture needs to be separated. Most commonly used steam-water separation equipment is a single-stage separation structure, such as baffle separators or cyclone separators. These separation devices have problems such as low separation efficiency and incomplete separation, resulting in steam still containing a lot of water, which affects the quality and performance of the steam. In addition, single-stage separation equipment has a large difference in the separation effect of water droplets of different particle sizes, making it difficult to meet the demand for high-purity steam.

[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a multi-stage steam-water separation tower to solve the problem that most existing steam-water separation equipment is a single-stage separation structure, such as baffle separators or cyclone separators. These separation devices have problems such as low separation efficiency and incomplete separation, resulting in steam still containing a lot of water, affecting the quality and use effect of steam. In addition, single-stage separation equipment has a large difference in the separation effect of water droplets of different particle sizes, which makes it difficult to meet the requirements of high-purity steam. Utility Model Content

[0004] This invention proposes a multi-stage steam-water separation tower, which solves the problem that most existing steam-water separation equipment is a single-stage separation structure, such as a baffle separator or a cyclone separator. These separation devices have problems such as low separation efficiency and incomplete separation, resulting in steam still containing a lot of water, affecting the quality and performance of the steam. In addition, single-stage separation equipment has a large difference in the separation effect of water droplets of different particle sizes, making it difficult to meet the requirements of high-purity steam.

[0005] The technical solution of this utility model is implemented as follows: a multi-stage steam-water separation tower includes: a tower body structure with an internal hollow structure, and a separation mechanism is fixedly connected to the inner side of the tower body structure. The separation mechanism is a pipe structure with an internal hollow structure.

[0006] The bottom of the outer circumferential surface of the separation mechanism has through slots arranged in a ring array. These through slots are steam discharge slots. A spiral separator is fixedly connected to the outer circumferential surface of the separation mechanism. The spiral separator is located above the steam discharge slots, and the inner wall of the spiral separator is in contact with the outer wall of the separation mechanism. The outer wall of the spiral separator is in contact with the inner wall of the tower body mechanism.

[0007] In a preferred embodiment, the spiral separator has through holes arranged in a ring array inside. These through holes are gas-liquid separation holes used to separate steam and liquid.

[0008] In a preferred embodiment, an exhaust pipe is fixedly connected to the outside of the tower body mechanism. The main body of the exhaust pipe is an L-shaped structure, and the exhaust pipe is connected to the tower body mechanism. A connecting flange is fixedly connected to the top surface of the exhaust pipe.

[0009] In a preferred embodiment, a mating flange is installed at the top of the connecting flange. The mating flange and the connecting flange together form a connection structure. Both the mating flange and the connecting flange have mounting holes arranged in a ring array inside, and fixing bolts are installed inside the mounting holes.

[0010] In a preferred embodiment, a pipe assembly is fixedly connected to the top surface of the mating flange. The main body of the pipe assembly is a bidirectional through structure on both the upper and lower sides, and the pipe assembly is connected to the exhaust pipe.

[0011] In a preferred embodiment, a control valve is installed on the outside of the pipe assembly, the control valve is used to control the opening of the valve plate in the pipe assembly, and a cover plate assembly is fixedly connected to the top surface of the separation mechanism.

[0012] In a preferred embodiment, the cover plate assembly extends upward to form a tower body mechanism, and a feed pipe is fixedly connected to the right side of the outer circumference of the separation mechanism. An inlet flange is fixedly connected to the right side of the feed pipe, and the inlet flange communicates with the feed pipe. A drain pipe is fixedly connected to the bottom end of the separation mechanism, and the drain pipe communicates with the separation mechanism. An external thread is provided on the front opening of the drain pipe, and a maintenance cover plate is screwed onto the front opening of the drain pipe.

[0013] After using the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this utility model, a more thorough separation of steam and water is achieved through a multi-stage separation structure. The separation mechanism first uses gravity to separate larger water droplets, and then guides the steam-water mixture into the spiral separator through the steam discharge tank. Smaller water droplets are separated by the centrifugal force generated by the spiral path. At the same time, the gas-liquid separation holes further capture fine water droplets, which solves the problems of low efficiency and incomplete separation in single-stage separation and improves the quality of steam.

[0015] 2. In this utility model, the multi-stage separation design achieves good separation effect for water droplets of different sizes, overcoming the defect of poor adaptability to water droplet size of single-stage separation equipment. Through the synergistic effect of the separation mechanism, spiral separation component and gas-liquid separation hole, the water content in the steam is greatly reduced, meeting the requirements for high-purity steam and avoiding the influence of moisture on the steam use effect. The steam-water separation tower is located in the middle section of the overall heat exchange structure of the boiler. In addition to separating steam and water, it also has the effect of slightly superheated steam, allowing the steam to have a better temperature under the same pressure, and can effectively generate low-pressure high-temperature steam.

Detailed Implementation

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown, a multi-stage steam-water separator includes: a tower body structure 1 with an internal hollow structure, and a separation mechanism 2 fixedly connected to the inner side of the tower body structure 1. The separation mechanism 2 is a pipe structure with an internal hollow structure.

[0026] The bottom of the outer peripheral surface of the separation mechanism 2 is provided with a through groove in a ring array. The through groove is a steam discharge groove 3. A spiral separator 301 is fixedly connected to the outer peripheral surface of the separation mechanism 2. The spiral separator 301 is located above the steam discharge groove 3. The inner wall of the spiral separator 301 is in contact with the outer wall of the separation mechanism 2. The outer wall of the spiral separator 301 is in contact with the inner wall of the tower body mechanism 1.

[0027] The spiral separator 301 has through holes arranged in a ring array inside. These through holes are gas-liquid separation holes 3011, which are used to separate steam and liquid. An exhaust pipe 101 is fixedly connected to the outside of the tower body mechanism 1. The main body of the exhaust pipe 101 is an L-shaped structure. The exhaust pipe 101 is connected to the tower body mechanism 1, and a connecting flange 1011 is fixedly connected to the top surface of the exhaust pipe 101.

[0028] The connecting flange 1011 has a mating flange 1012 installed at its top. The mating flange 1012 and the connecting flange 1011 together form a connection structure. The mating flange 1012 and the connecting flange 1011 both have mounting holes arranged in a ring array inside. Fixing bolts 1013 are installed inside the mounting holes. A pipe assembly 1014 is fixedly connected to the top surface of the mating flange 1012. The main body of the pipe assembly 1014 has a bidirectional through structure on both the top and bottom sides. The pipe assembly 1014 is connected to the exhaust pipe 101.

[0029] Among them, a control valve 1015 is installed on the outside of the pipe assembly 1014. The control valve 1015 is used to control the opening of the valve plate in the pipe assembly 1014. A cover plate assembly 201 is fixedly connected to the top surface of the separation mechanism 2. The cover plate assembly 201 extends upward to the tower body mechanism 1. A feed pipe 2011 is fixedly connected to the right side of the outer peripheral surface of the separation mechanism 2. An access flange 2012 is fixedly connected to the right side of the feed pipe 2011. The access flange 2012 communicates with the feed pipe 2011. A drain pipe 2013 is fixedly connected to the bottom end of the separation mechanism 2. The drain pipe 2013 communicates with the separation mechanism 2. An external thread is opened on the front opening of the drain pipe 2013. A maintenance cover plate 2014 is screwed onto the front opening of the drain pipe 2013.

[0030] In use, the soda-water mixture enters the feed pipe 2011 through the inlet flange 2012 and is then transported to the separation mechanism 2 by the feed pipe 2011. The soda-water mixture entering the separation mechanism 2 flows upward along its internal hollow pipe. During the flow, some larger water droplets sink due to gravity and are temporarily stored through the drain pipe 2013 at the bottom of the separation mechanism 2.

[0031] The remaining steam-water mixture continues to flow upwards. When it reaches the steam discharge tank 3 on the outer periphery of the separation mechanism 2, the steam carries some small-diameter water droplets through the steam discharge tank 3 into the space between the separation mechanism 2 and the tower body mechanism 1.

[0032] The steam-water mixture entering the space flows along the spiral path of the spiral separator 301. Under the action of centrifugal force, water droplets are thrown towards the inner wall of the spiral separator 301. Some of the water droplets seep into the inner side of the spiral separator 301 through the gas-liquid separation hole 3011 on the spiral separator 301, slide down the outer wall of the separation mechanism 2 to the steam discharge tank 3, and finally flow into the drain pipe 2013.

[0033] The steam separated by the spiral separator 301 continues to flow upward and enters the upper space of the tower body mechanism 1. Finally, it is transported to the pipe assembly 1014 through the exhaust pipe 101 and discharged under the control of the control valve 1015.

[0034] The connecting flange 1011 and the docking flange 1012 are fixed by the fixing bolt 1013 to ensure the sealed connection between the exhaust pipe 101 and the pipe assembly 1014. The cover plate assembly 201 covers the top of the separation mechanism 2 to prevent steam from leaking from the top of the separation mechanism 2. The maintenance cover plate 2014 can be opened when needed to clean and maintain the drain pipe 2013.
