Description

Technical Field

[0001] The utility model relates to the technical field of boiler waste steam treatment, and more specifically, to a centrifugal cylinder shell with good separation effect. Background Art

[0002] In the production process of the cigarette industry, the boiler system plays a key role, which is responsible for providing the heat energy required for the production process. However, a large amount of waste steam is generated during the operation of the boiler, which is usually directly discharged into the atmosphere as waste water steam. This treatment method has certain problems, the most important of which are energy waste and environmental pollution. In the cigarette industry, energy is an indispensable resource in the production process, so the waste of energy causes direct economic losses to the enterprise. In addition, the waste water steam discharged into the atmosphere contains a large amount of water vapor and harmful gases, which will pollute the environment and affect the living quality of the surrounding residents. Therefore, it is of great significance to solve the problems of energy waste and environmental pollution in the process of boiler waste steam treatment.

[0003] At present, in view of the problem of boiler waste steam treatment, some solutions have been proposed. Among them, a common treatment method is to separate water vapor by centrifugal separation. However, in this existing treatment method, the outer shell of the centrifugal cylinder is just a smooth shell structure, resulting in poor water vapor separation effect. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a centrifugal cylinder shell with good separation effect, in order to solve the technical problems existing in the background art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] The centrifugal cylinder housing disclosed in this application has a novel structure and strong practicability. The centrifugal separator using this centrifugal cylinder housing can basically completely separate water vapor. The outer part of the centrifugal cylinder housing of this application is distributed with separation flanges and centrifugal fins. The exhaust steam enters downward through the exhaust steam inlet. The centrifugal cylinder rotates clockwise when viewed from the direction of the main motor. The centrifugal fins separate the condensed water in the exhaust steam towards the inner wall of the housing, making the separation force direction towards the bottom of the housing. At the same time, a larger centrifugal force is generated through the separation flanges to improve the separation effect of the condensed water. After the condensed water is separated, it is collected at the bottom of the lower housing and directly discharged from the condensed water discharge port of the lower housing.

[0025] Embodiment 1:

[0026] Figures 1-6, A water-vapor separation and recovery device, comprising: a centrifugal separator 100, a deaerator 400, and a water pump 300; the centrifugal separator 100 is used for separating water vapor from waste steam; the separated steam enters the auxiliary heating port of the deaerator 400 through a steam pipeline 101; the separated condensed water enters a condensed water collection tank 200 through a separated condensed water pipeline 102, and the water pump 300 is used for pumping the condensed water collected by the condensed water collection tank 200 into the condensed water reuse port of the deaerator 400 through a condensed water pipeline 301; the deoxygenated water is pumped into a boiler 500 for use through a water supply pipeline 401.

[0027] This application provides a water-vapor separation and recovery device, comprising a centrifugal separator 100, a heat-insulating pipeline, a deaerator 400, and a boiler 500. The centrifugal separator 100 is used for separating water vapor. The separated water is transported to the deaerator 400 through the heat-insulating pipeline, and then transported to the boiler 500 for heating through the heat-insulating pipeline, so as to improve the energy utilization rate and reduce the energy consumption cost. Its advantage lies in being able to completely separate water vapor, realizing the singleness of the material transportation state, improving the energy utilization rate while reducing the energy consumption cost. The functions of each core component are as follows:

[0028] Centrifugal separator 100: Located at the head of the water-vapor separation and recovery device, its main function is to separate water vapor from waste steam by centrifugal force. The internal structure of the centrifugal separator 100 is reasonably designed, and an efficient separation technology is adopted, which can realize the rapid and complete separation of water vapor.

[0029] Heat-insulating pipeline: Comprising a steam pipeline 101, a condensed water pipeline 301, and a water supply pipeline 401, a pipeline system connecting the centrifugal separator 100, the deaerator 400, and the boiler 500, whose main function is to transport the separated water vapor to the next step for treatment. The heat-insulating pipeline adopts an efficient heat-insulating material to ensure that the separated water vapor can maintain an appropriate temperature during transportation, avoiding energy and water quality losses.

[0030] Deaerator 400: Located in the middle of the heat-insulating pipeline, its main function is to remove oxygen in water. The deaerator 400 is an existing technology, so it will not be elaborated here too much. It can effectively adsorb and remove oxygen in water, protect the boiler 500 system from corrosion, and extend the service life of the equipment.

[0031] Boiler 500: Located at the end of the heat-insulating pipeline, it is the final destination of the entire water-vapor separation and recovery device. The separated water vapor is transported to the boiler 500 through the heat-insulating pipeline for heating, and the water vapor is converted into steam through a heating system to meet various requirements in the production process. The heating system of the boiler 500 is designed efficiently and can quickly heat the water vapor to a high temperature and high pressure state to realize the reuse of steam.

[0032] In some embodiments, the centrifugal separator 100 includes: a housing, a centrifugal cylinder 3, a sealed drive device, a main motor 1, and an exhaust unit. The upper side of the housing has an exhaust steam inlet 5, the lower part has a condensate drain port 12, and the top has an air outlet. The centrifugal cylinder 3 is rotatably arranged in the housing and is used for separating water vapor from the exhaust steam introduced into the housing. The sealed drive device penetrates through the lower part of the housing and is connected to the centrifugal cylinder 3. The main motor 1 is arranged outside the housing and is used for driving the sealed drive device to rotate. The exhaust unit is arranged at the air outlet and is used for discharging the gas after water vapor separation. The exhaust steam introduced from the exhaust steam inlet passes through the centrifugal cylinder 3 for water and gas separation, so that the separated liquid is discharged from the condensate drain port 12 at the lower part, and the separated steam is discharged from the air outlet.

[0033] The centrifugal separator 100 is one of the key components of the water vapor separation and recovery equipment, and its performance directly affects the separation effect. In actual design, internal components of the centrifugal separator 100 can be made of corrosion-resistant and wear-resistant materials, such as stainless steel, acid and alkali-resistant materials, etc., to ensure the long-term stable operation of the equipment.

[0034] Specifically, the housing includes an upper housing 10 and a lower housing, and the upper housing and the lower housing are hermetically connected by connecting bolts 13 and sealing rings. The exhaust steam inlet is opened on the side wall of the upper housing, the air outlet is opened on the top of the upper housing, and the condensate drain port 12 is opened at the bottom of the lower housing.

[0035] In some embodiments, the centrifugal cylinder 3 includes: a centrifugal cylinder 3 body and a spoke spindle unit. The centrifugal cylinder 3 body is larger at the bottom and smaller at the top, and both the bottom and the top of the centrifugal cylinder 3 body are open. Specifically, the upper part of the centrifugal cylinder 3 body is frustum-shaped. And there is a gap between the top opening of the centrifugal cylinder 3 body and the air outlet. There is a gap between the bottom opening of the centrifugal cylinder 3 body and the bottom of the housing. The spoke spindle unit is arranged inside the centrifugal cylinder 3 body and is connected to the inner wall of the centrifugal cylinder 3 body. The lower part of the spoke spindle unit is connected to the sealed drive device.

[0036] In the cross-section of the centrifugal cylinder body, the included angle between the upper frustum-shaped side wall and the lower cylindrical side wall is 25° - 35°. Within this range, the best design effect of water vapor separation can be achieved.

[0037] In some embodiments, separation flanges 3.1 are respectively connected to the top, end, and lower end of the centrifugal cylinder 3 body at the frustum shape, and the separation flanges 3.1 are arranged obliquely downward. A number of centrifugal fins 3.2 are respectively provided on the outer wall of the frustum shape of the centrifugal cylinder 3 body and the outer wall of the lower part of the centrifugal cylinder 3 body, and the centrifugal fins are arranged obliquely.

[0038] That is, the separating flange 3.1 is divided into an upper flange, a middle flange, and a lower flange to prevent the structure from being too complex while ensuring the separation effect. The upper flange increases the centrifugal force at the upper part of the separating cylinder and prevents condensed water from entering the exhaust unit 6 along the outer edge of the steam inlet hood. The centrifugal fins have a certain torsion angle, causing the separation direction to face downward. Some of the droplets adhering to the separating cylinder gather downward. By setting the middle flange and the lower flange to increase the separation centrifugal force, it is ensured that this part of the liquid can be effectively separated. The lower flange increases the centrifugal force at the lower air inlet of the centrifugal cylinder 3 and at the same time increases the diameter of the suction port, thereby reducing the suction force on the liquid and preventing the liquid from being sucked into the interior of the separating cylinder.

[0039] In some embodiments, the sealed drive device includes: a sealing device 2 and a coupling central shaft unit. The coupling central shaft unit rotatably seals through the lower part of the housing. The lower part of the coupling central shaft unit is fixedly connected to the main motor 1. The coupling central shaft unit is arranged in the sealing device 2, and the top of the coupling central shaft unit is fixedly connected to the lower part of the separating cylinder main shaft; the sealing device 2 is used to isolate and seal the coupling central shaft unit.

[0040] The sealing device 2 includes a sealing device 2 main body and a sealing cover. The diameter of the lower part of the sealing device 2 main body is larger than that of the upper part. This is more conducive to improving the stability of the overall structure during rotation. The sealing device 2 main body is hermetically connected to the bottom of the housing. An installation cavity is provided in the sealing device 2 main body. The coupling central shaft unit is arranged in the installation cavity. The sealing cover is installed on the sealing device 2 main body for isolating and sealing the coupling central shaft unit.

[0041] The coupling central shaft unit includes a coupling central shaft 2.2 and a main drive bearing 2.1. The diameter of the lower part of the installation cavity is larger than that of the upper part of the installation cavity. Main drive bearings are installed in the lower part, the middle part, and the upper part of the installation cavity. The coupling central shaft is rotatably connected to the sealing device 2 main body through the main drive bearings provided in the lower part, the middle part, and the upper part of the installation cavity; the upper part of the coupling central shaft penetrates through the sealing cover in a sealed manner and is connected to the separating cylinder main shaft; the lower part of the coupling central shaft is connected to the main motor 1.

[0042] The coupling central shaft is rotatably and hermetically connected to the bottom wall of the housing through a sealing ring; the sealing device 2 main body is hermetically connected to the bottom of the housing through a sealing ring. The sealing cover is hermetically connected to the sealing device 2 main body through a sealing ring, and the sealing cover is rotatably and hermetically connected to the coupling central shaft through a sealing ring.

[0043] The main motor 1 is located at the central position outside the lower housing, and the sealing device 2 is located at the central position inside the lower housing. The housings of both are fixedly connected to the inside and outside of the lower housing. The central shaft of the coupling rotates freely through three pairs of main drive bearings. The shaft of the main motor 1 is connected to the separation cylinder main shaft of the centrifugal cylinder 3 through the central shaft of the coupling, thereby transmitting the power of the main motor 1. The main motor 1 drives the centrifugal cylinder 3 to rotate through the sealing device 2, and internal condensed water leakage is prevented through the seal.

[0044] Separation flanges 3.1 and centrifugal fins are distributed on the outer part of the separation cylinder. The exhaust steam enters downward through the exhaust steam inlet. The centrifugal cylinder 3 rotates clockwise when viewed from the direction of the main motor 1. The centrifugal fins separate the condensed water in the exhaust steam towards the inner wall of the housing, and the centrifugal fins have a certain twist angle, so that the direction of the separating force faces the bottom of the housing. At the same time, a relatively large centrifugal force is generated through the separation flange 3.1 to improve the separation effect of the condensed water. After the condensed water is separated, it is collected at the bottom of the lower housing and directly discharged from the condensed water drain port 12.

[0045] The centrifugal fins extend on the separation flange 3.1. One is to enable the separation fins to obtain a better centrifugal effect, and the other is to further strengthen the structure of the separation flange 3.1.

[0046] In some embodiments, the spoke main shaft unit includes: a separation cylinder main shaft 3.4, upper separation cylinder spokes 3.5, lower separation cylinder spokes 3.3. A plurality of the upper separation cylinder spokes and lower separation cylinder spokes are respectively arranged on the separation cylinder main shaft, and the other ends of the upper separation cylinder spokes and lower separation cylinder spokes are respectively connected to the inner wall of the centrifugal cylinder 3 body; the lower end of the separation cylinder main shaft is connected to the sealing drive device.

[0047] In some embodiments, the centrifugal cylinder 3 is key-connected to the separation cylinder main shaft through the lower separation cylinder spokes and upper separation cylinder spokes and fixed by a separation cylinder fixing nut 3.6. The spoke main shaft unit further includes: a steam inlet hood 4. The middle of the steam inlet hood has a through hole adapted to the top opening of the centrifugal cylinder 3 body. The end of the through hole is provided with an air inlet piece extending obliquely downward, and there is a gap between the air inlet piece and the upper separation flange 3.1. The spoke main shaft unit further includes: steam inlet hood spokes 4.2, an upper end bearing 4.1. The upper end bearing is connected to the inner side of the air inlet piece through the steam inlet hood spokes, and the upper part of the separation cylinder main shaft is connected to the upper end bearing.

[0048] The exhaust unit drives the exhaust turbine through an exhaust motor to discharge the steam in the exhaust steam through the exhaust port 8. Since the centrifugal effect of the separation cylinder on the steam is small, the steam runs upward and will enter the exhaust unit from the outer edge of the steam inlet hood when the exhaust unit is operating. At the same time, when the lower separation cylinder spokes rotate with the separation cylinder, an upward air flow will be generated, which can send the steam generated by the condensed water in the lower housing upward and enter the exhaust unit through the steam inlet hood.

[0049] The exhaust unit includes: an exhaust cavity, an exhaust turbine 6.1, and an exhaust motor 7. The exhaust cavity is arranged at the upper part of the upper shell and is adapted to the air outlet. The exhaust turbine is rotatably arranged in the exhaust cavity. The exhaust motor is arranged at the upper part of the exhaust cavity and is used to drive the exhaust turbine to rotate, and the steam after water-vapor separation is discharged through an exhaust port arranged on the exhaust cavity.

[0050] It further includes a pressure sensor 9. The pressure sensor is arranged on the side wall of the exhaust cavity and is located below the exhaust turbine. The exhaust motor can be a variable-frequency adjustable motor. The negative pressure is detected through the pressure sensor, and the frequency of the exhaust motor is adjusted to balance the positive and negative pressure difference between the lower spokes of the separation cylinder and the exhaust unit, so as to effectively discharge the steam.

[0051] The condensed water formed at the top of the upper shell is prevented from entering the exhaust unit from the outer edge of the steam inlet cover due to the combined action of the horn-shaped structure of the steam inlet cover and the separation flange 3.1 located at the top of the separation cylinder.

[0052] The bottom diameter of the separation cylinder is large, and a separation flange 3.1 is arranged. The sealing device 2 forms a circular water-blocking boss to prevent condensed water from entering the interior of the separation cylinder from the lower part.

[0053] The centrifugal separator 100 is provided with a safety valve 14 to prevent abnormal overpressure of the internal pressure, and is provided with a liquid level detector 15. By detecting the liquid level, it prevents the separation failure caused by too high internal condensed water.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
