Description

[0001] The invention relates to the technical field of boiler exhaust steam treatment, and more particularly to a centrifugal separator. Background Art

[0002] In the production process of the cigarette industry, the boiler system plays a key role, which is responsible for providing the required heat energy for the production process. However, during the operation of the boiler, a large amount of exhaust steam is generated, which is usually regarded as waste water vapor and discharged directly into the atmosphere. There are certain problems with this treatment method, 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 vapor discharged into the atmosphere contains a large amount of water vapor and harmful gases, which will pollute the environment and affect the quality of life of surrounding residents. Therefore, it is of great significance to solve the problems of energy waste and environmental pollution in the process of boiler exhaust steam treatment.

[0037] Embodiment 1:

[0038] Figure 1-Figure 6 A water vapor separation and recovery device comprises: a centrifugal separator 100, a deaerator 400, and a water pump 300; the centrifugal separator 100 is used to separate water vapor from exhaust steam; the separated steam enters the auxiliary heating port of the deaerator 400 through the steam pipeline 101; the separated condensed water enters the condensed water collection tank 200 through the separation condensed water pipeline 102, and the water pump 300 is used to pump the condensed water collected in the condensed water collection tank 200 into the condensed water reuse port of the deaerator 400 through the condensed water pipeline 301; the deoxygenated water is pumped into the boiler 500 for use through the water supply pipeline 401.

[0039] The present application provides a water vapor separation and recovery device, including a centrifugal separator 100, an insulated pipeline, a deaerator 400 and a boiler 500. The centrifugal separator 100 is used to separate water vapor, and the separated water is transported to the deaerator 400 through the insulated pipeline, and then transported to the boiler 500 through the insulated pipeline for heating, so as to improve energy utilization and reduce energy consumption costs. Its advantage is that it can completely separate water vapor, realize the simplification of material transportation state, improve energy utilization and reduce energy consumption costs. The functions of each core component are as follows:

[0040] Centrifugal separator 100: Located at the head of the water vapor separation and recovery equipment, its main function is to separate water vapor from exhaust steam by centrifugal force. The internal structure of the centrifugal separator 100 is reasonably designed, and it adopts efficient separation technology to achieve rapid and thorough separation of water vapor.

[0041] Insulated pipeline: including steam pipeline 101, condensate pipeline 301, water supply pipeline 401, and the pipeline system connecting the centrifugal separator 100, deaerator 400 and boiler 500, the main function of which is to transport the separated water vapor to the next step for treatment. The insulated pipeline adopts high-efficiency insulation materials to ensure that the separated water vapor can maintain a suitable temperature during the transportation process to avoid the loss of energy and water quality.

[0042] Deaerator 400: Located in the middle of the insulation pipeline, its main function is to remove oxygen from the water. Deaerator 400 is a prior art, so it will not be elaborated here. It can effectively absorb and remove oxygen from the water, protect the boiler 500 system from corrosion, and extend the service life of the equipment.

[0043] Boiler 500: Located at the end of the insulated pipeline, it is the final destination of the entire water vapor separation and recovery equipment. The separated water vapor is transported to the boiler 500 through the insulated pipeline for heating, and the water vapor is converted into steam through the heating system to meet various needs in the production process. The heating system of boiler 500 is designed to be efficient and can quickly heat the water vapor to a high temperature and high pressure state to achieve the reuse of steam.

[0044] In some embodiments, the centrifugal separator 100 includes: a shell, a centrifugal cylinder 3, a sealing transmission device, a main motor 1, and an exhaust unit. The upper side of the shell has an exhaust steam inlet 5, the lower part has a condensed water outlet 12, and the top has an air outlet; the centrifugal cylinder 3 is rotatably arranged in the shell, and is used to separate the exhaust steam introduced into the shell from water vapor; the sealing transmission device is arranged through the lower part of the shell and is connected to the centrifugal cylinder 3; the main motor 1 is arranged outside the shell, and is used to drive the sealing transmission device to rotate; the exhaust unit is arranged at the air outlet, and is used to discharge the gas after the water vapor is separated. The exhaust steam introduced from the exhaust steam inlet is separated from the water vapor through the centrifugal cylinder 3, so that the separated liquid is discharged from the condensed water outlet 12 at the lower part, and the separated steam is discharged from the air outlet.

[0045] 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, corrosion-resistant and wear-resistant materials such as stainless steel and acid- and alkali-resistant materials can be used to make the internal components of the centrifugal separator 100 to ensure the long-term stable operation of the equipment.

[0046] Specifically, the shell includes an upper shell 10 and a lower shell, and the upper shell and the lower shell are sealed and connected by connecting bolts 13 and sealing rings; the exhaust steam inlet is opened on the side wall of the upper shell, the air outlet is opened on the top of the upper shell, and the condensate outlet 12 is opened on the bottom of the lower shell.

[0047] In some embodiments, the centrifugal barrel 3 includes: a centrifugal barrel 3 body and a spoke spindle unit. The centrifugal barrel 3 body is larger at the bottom and smaller at the top, and the bottom and top of the centrifugal barrel 3 body are both opened. Specifically, the upper part of the centrifugal barrel 3 body is truncated cone-shaped; and there is a gap between the top opening of the centrifugal barrel 3 body and the air outlet; there is a gap between the bottom opening of the centrifugal barrel 3 body and the bottom of the shell; the spoke spindle unit is arranged in the centrifugal barrel 3 body and connected to the inner wall of the centrifugal barrel 3 body; the lower part of the spoke spindle unit is connected to the sealing transmission device.

[0048] In some embodiments, the centrifugal cylinder 3 body is connected with a separation flange 3.1 at the top and end of the truncated cone and the lower end of the centrifugal cylinder 3 body, and the separation flange 3.1 is arranged downwardly inclined. The centrifugal cylinder 3 body is provided with a plurality of centrifugal fins 3.2 on the outer wall of the truncated cone and the outer wall of the lower part of the centrifugal cylinder 3 body, and the centrifugal fins are arranged inclined.

[0049] That is, the separation flange 3.1 is divided into an upper flange, a middle flange and a lower flange to ensure the separation effect while preventing the structure from being too complicated. The upper flange increases the centrifugal force on the upper part of the separation cylinder to prevent condensed water from entering the exhaust unit 6 from the outer edge of the steam inlet hood. The centrifugal ribs have a certain torsion angle, so that the separation direction is toward the bottom, and some droplets attached to the separation cylinder are gathered downward. By setting the middle flange and the lower flange to increase the separation centrifugal force, it can be ensured that this part of the liquid is effectively separated. The lower flange increases the centrifugal force of the lower air inlet of the centrifugal cylinder 3, and at the same time increases the diameter of the suction port to reduce the suction force on the liquid, preventing the liquid from being sucked into the separation cylinder.

[0050] In some embodiments, the sealing transmission device includes: a sealing device 2 and a coupling center axis unit, wherein the rotating seal of the coupling center axis unit passes through the lower part of the shell, the lower part of the coupling center axis unit is fixedly connected to the main motor 1, the coupling center axis unit is arranged in the sealing device 2, and the top of the coupling center axis unit is fixedly connected to the lower part of the separation barrel main shaft; the sealing device 2 is used to isolate and seal the coupling center axis unit.

[0051] The sealing device 2 includes a sealing device 2 body and a sealing cover, wherein the lower diameter of the sealing device 2 body is larger than the upper diameter. This is more conducive to improving the stability of the overall structure during rotation. The sealing device 2 body is sealed and connected to the bottom of the housing, and a mounting cavity is provided in the sealing device 2 body. The coupling central axis unit is arranged in the mounting cavity, and the sealing cover is installed on the sealing device 2 body to isolate and seal the coupling central axis unit.

[0052] The coupling center axis unit includes a coupling center axis 2.2 and a main drive bearing 2.1. The lower diameter of the installation cavity is larger than the upper diameter 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 center axis is rotatably connected to the main body of the sealing device 2 through the main drive bearings arranged in the lower part, the middle part and the upper part of the installation cavity; the upper seal of the coupling center axis passes through the sealing cover and is connected to the main shaft of the separation cylinder; the lower part of the coupling center axis is connected to the main motor 1.

[0053] The central axis of the coupling is rotatably sealed to the bottom wall of the shell via a sealing ring; the main body of the sealing device 2 is rotatably sealed to the bottom of the shell via a sealing ring, the sealing cover is rotatably sealed to the main body of the sealing device 2 via a sealing ring, and the sealing cover is rotatably sealed to the central axis of the coupling via a sealing ring.

[0054] The main motor 1 is located at the center of the outer part of the lower shell, and the sealing device 2 is located at the center of the inner part of the lower shell. Both shells are fixedly connected to the inner and outer parts of the lower shell. The central axis of the coupling is freely rotated through three pairs of main transmission bearings. The shaft of the main motor 1 is connected to the main axis of the separation cylinder of the centrifugal cylinder 3 through the central axis 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 the internal condensed water is prevented from leaking through the seal.

[0055] The outside of the separation cylinder is provided with a separation flange 3.1 and centrifugal fins. 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 toward the inner wall of the shell. The centrifugal fins have a certain torsion angle, so that the separation force is directed toward the bottom of the shell. At the same time, a larger centrifugal force is generated by the separation flange 3.1 to improve the condensed water separation effect. After separation, the condensed water gathers at the bottom of the lower shell and is directly discharged from the condensed water outlet 12.

[0056] The centrifugal fins extend on the separation flange 3.1, firstly, to enable the separation fins to obtain a better centrifugal effect, and secondly, to further strengthen the separation flange 3.1 in structure.

[0057] In some embodiments, the spoke spindle unit includes: a separation cylinder spindle 3.4, an upper spoke 3.5 of the separation cylinder, a lower spoke 3.3 of the separation cylinder, and a plurality of the upper spokes of the separation cylinder and the lower spokes of the separation cylinder are respectively arranged on the separation cylinder spindle, and the other ends of the upper spokes of the separation cylinder and the lower spokes of the separation cylinder are respectively connected to the inner wall of the centrifugal cylinder 3 body; the lower end of the separation cylinder spindle is connected to the sealing transmission device.

[0058] In some embodiments, the centrifugal cylinder 3 is key-connected to the separation cylinder main shaft through the lower spokes of the separation cylinder and the upper spokes of the separation cylinder, and is fixed by the separation cylinder fixing nut 3.6. The spoke main shaft unit also includes: a steam inlet hood 4, the middle part of which has a through hole that matches the top opening of the centrifugal cylinder 3 body, and the end of the through hole is provided with an air intake sheet that extends obliquely downward, and there is a gap between the air intake sheet and the separation flange 3.1 on the upper side. The spoke main shaft unit also includes: a steam inlet hood spoke 4.2, an upper end bearing 4.1, the upper end bearing is connected to the inner side of the air intake sheet through the steam inlet hood spokes, and the upper part of the separation cylinder main shaft is connected to the upper end bearing.

[0059] The exhaust unit drives the exhaust turbine through the exhaust port via the exhaust motor to discharge the steam in the exhaust steam. Since the centrifugal effect of the separation cylinder on the steam is small, the steam runs upward and enters the exhaust unit from the outer edge of the steam inlet hood when the exhaust unit is running. At the same time, the spokes under the separation cylinder will generate an upward airflow when the separation cylinder rotates, which can send the steam generated by the condensed water in the lower shell to the upper part and enter the exhaust unit through the steam inlet hood.

[0060] The exhaust unit includes: an exhaust cavity, an exhaust wheel 6.1, and an exhaust motor 7. The exhaust cavity is arranged on the upper part of the upper shell and is adapted to the air outlet. The exhaust wheel is rotatably arranged in the exhaust cavity. The exhaust motor is arranged on the upper part of the exhaust cavity and is used to drive the exhaust wheel to rotate and discharge the steam after water vapor separation through the exhaust port arranged on the exhaust cavity.

[0061] It also includes a pressure sensor 9, which is arranged on the side wall of the exhaust cavity and below the exhaust wheel. The exhaust motor can be a variable frequency motor, which detects negative pressure through the pressure sensor, adjusts the exhaust motor frequency, balances the positive and negative pressure difference between the spokes under the separation cylinder and the exhaust unit, and realizes effective steam discharge.

[0062] The condensed water formed on the top of the upper shell is prevented from entering the exhaust unit from the outer edge of the steam inlet hood due to the combined effect of the trumpet-shaped structure of the steam inlet hood and the separation flange 3.1 located on the top of the separation cylinder.

[0063] The bottom of the separation cylinder has a large diameter and is provided with a separation flange 3.1. The sealing device 2 forms a circular water retaining boss to prevent condensed water from entering the interior of the separation cylinder from the bottom.

[0064] 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 to detect the liquid level to prevent separation failure caused by excessive internal condensed water.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
