Description

Technical Field

[0001] This invention relates to the field of sugarcane cooking exhaust equipment technology, and in particular to a steam guiding and gathering device for a sugarcane cooking pot. Background Technology

[0002] Sugarcane boiling pots are common heating equipment in sugar refining and deep processing of sugarcane, widely used in the traditional and industrial production of syrups, brown sugar, and other foods. During the boiling of sugarcane juice, the pot needs continuous heating to bring the juice to a boil, generating a large amount of high-temperature steam. Traditional production methods typically use open boiling pots, allowing the steam to escape directly. This not only leads to increased workshop temperature and humidity but also causes problems such as deterioration of workshop hygiene, equipment corrosion, and safety hazards. Furthermore, the high-temperature steam carries away a significant amount of moisture, resulting in water waste. Summary of the Invention

[0003] To address or partially address the problems existing in related technologies, this invention provides a steam diversion and collection device and method for sugarcane cooking pots, aiming to solve the technical problem that direct discharge of steam generated during the sugarcane cooking process into the workshop leads to increased workshop temperature, increased humidity, deterioration of workshop environmental hygiene, and corrosion of equipment in the workshop.

[0004] The aforementioned steam guiding and gathering device for a sugarcane cooking pot includes a cyclone separator, a steam collection hood, and a cold air acceleration pipe; The top of the cyclone separator is provided with an air inlet pipe, and the free end of the air inlet pipe is connected to the top of the steam collection hood through a pipe. The air inlet pipe is equipped with a cold air acceleration pipe, which is coaxially arranged with the air inlet pipe. The outer diameter of the cold air acceleration pipe is smaller than the inner diameter of the air inlet pipe. The air outlet of the cold air acceleration pipe is arranged in the same direction as the air outlet of the air inlet pipe. The air inlet of the cold air acceleration pipe is connected to the air supply equipment through a connecting pipe. The steam collected by the steam collection hood is transported to the air inlet pipe through a pipeline, and after mixing with the cold air transported by the cold air acceleration pipe, they are introduced into the cyclone separator together.

[0005] In some designs, the free end of the air inlet duct is connected to the cold air acceleration duct, and the air inlet duct is connected to the top of the steam collection hood via a pipe.

[0006] In some designs, a cooling cylinder is provided on the outside of the cyclone separator, and a cooling chamber is provided between the cooling cylinder and the cyclone separator. A cooling water inlet pipe is provided at the bottom of the cooling chamber, and a cooling water outlet pipe is provided at the top of the cooling chamber.

[0007] In some embodiments, the cooling chamber is provided with a spiral-shaped first guide vane, which divides the internal cavity of the cooling chamber into a spiral-shaped cooling channel. The lower end of the cooling channel is connected to the cooling water inlet pipe, and the upper end of the cooling channel is connected to the cooling water outlet pipe.

[0008] In some designs, a water tank is provided on the cooling water inlet pipe, and the connecting pipe portion is located inside the water tank.

[0009] In some embodiments, the connecting pipe has a cleaning inlet pipe on the portion of the pipe inside the water tank, and the cleaning inlet pipe has a valve, with the valve stem passing through the water tank, thereby placing the valve handwheel outside the water tank.

[0010] In some designs, a spiral-shaped second guide vane is provided on the inner wall of the cyclone separator.

[0011] In some designs, the inner wall of the cyclone separator is provided with an air inlet guide shroud, one end of which covers the outlet of the air inlet pipe, and the bottom of the other end extends to the upper end of the second guide vane.

[0012] In some designs, the bottom of the cyclone separator is provided with a condensate outlet pipe, and a drain valve is provided on the condensate outlet pipe; The top of the cyclone separator is equipped with an exhaust pipe; The air supply equipment uses a high-speed direct-drive centrifugal fan; The steam collection hood is equipped with a steam collection fan.

[0013] This application also provides a method for steam diversion and collection in a sugarcane cooking pot using the aforementioned steam diversion and collection device, specifically including the following steps. S1: Place a steam collection hood over the sugarcane cooking pot to collect the boiling steam from the sugarcane cooking pot, and then transport it through a pipeline to the air inlet pipe of the cyclone separator. S2: The air supply equipment introduces cold air into the air inlet pipe through the cold air acceleration pipe, mixes it with steam, and then blows it into the cyclone separator. S3: The cyclone separator separates the moisture and air in the steam. The moisture is discharged from the bottom of the cyclone separator, and the air is discharged from the top of the cyclone separator.

[0014] The technical solution provided by this invention may include the following beneficial effects: This application introduces a cold air acceleration pipe inside the air inlet duct. The cold air ejected through the acceleration pipe carries the steam collected by the air inlet guide shroud and injects it at high speed into the cyclone separator. This effectively increases the flow velocity of the steam within the cyclone separator, enabling it to effectively separate moisture from the steam. Simultaneously, the mixing of cold air and steam effectively reduces the steam temperature, making it easier for moisture in the steam to condense into water droplets, thus improving the separation effect of the cyclone separator.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described.

[0020] The current solution addresses the problems caused by the direct release of steam generated during the sugarcane cooking process into the workshop, which can lead to increased workshop temperature, humidity, deterioration of workshop hygiene, and corrosion of equipment. This solution involves installing an exhaust hood above the sugarcane cooking pot, with the hood's pipes connected to the outside of the workshop to release the steam, effectively preventing the steam from affecting the workshop environment, equipment, and personnel.

[0021] In the above solutions, since steam contains a large amount of moisture, directly releasing this steam into the atmosphere would waste water resources.

[0022] In order to recover moisture from steam and reduce water waste, it is proposed to use cyclone separator 1 to recover moisture from steam. However, the steam flow rate from the exhaust hood is slow. If it is directly introduced into cyclone separator 1, the steam flow rate in cyclone separator 1 will also be very slow, and the moisture in steam cannot be effectively separated.

[0023] To address the aforementioned technical issues, this application provides the following steam guiding and gathering device for a sugarcane cooking pot.

[0024] Example 1: like Figure 1 and Figure 2 As shown, this application provides a steam guiding and gathering device for a sugarcane cooking pot, including a cyclone separator 1, a steam collection hood 2, and a cold air acceleration pipe 3.

[0025] The cyclone separator 1 is generally conical in shape, gradually tapering downwards. An exhaust pipe 106 is located at the center of the top surface of the cyclone separator 1 to remove dry steam from inside the separator. A condensate outlet pipe 104 is located at the bottom of the cyclone separator 1, and a drain valve 105 is installed on the condensate outlet pipe 104. The drain valve 105 is a float-type drain valve used to automatically drain water collected at the bottom of the cyclone separator 1. In some embodiments, the condensate outlet pipe 104 is connected to an external water storage tank to recover moisture from the steam.

[0026] The top of the cyclone separator 1 is provided with an air inlet pipe 101, which is tangential to the cyclone separator 1. This allows the airflow introduced into the cyclone separator 1 from the air inlet pipe 101 to flow along the inner wall of the cyclone separator 1 in a tangential direction, forming a spiral downward airflow inside the cyclone separator 1. Under the action of strong centrifugal force, the larger water droplets in the steam are quickly "thrown" towards the inner wall of the cyclone separator 1. After the water droplets hit the wall, they lose kinetic energy and condense into a thin water film along the wall. Driven by the spiral airflow and its own gravity, this water film flows downward along the cylinder wall and eventually flows into the liquid collection area at the bottom of the cyclone separator 1. Then, it is automatically discharged from the cyclone separator 1 through the drain valve 105.

[0027] The dry steam with a very small mass remains concentrated in the central region due to the small centrifugal force. The dry steam, whose moisture has been removed, flows upward and enters the atmosphere from the exhaust pipe 106 at the top.

[0028] The air inlet pipe 101 is equipped with a cold air acceleration pipe 3, which is coaxially arranged with the air inlet pipe 101. The outer diameter of the cold air acceleration pipe 3 is smaller than the inner diameter of the air inlet pipe 101, thereby forming a gap between the outer wall of the cold air acceleration pipe 3 and the inner wall of the air inlet pipe 101, allowing steam to pass through. The outlet end of the cold air acceleration pipe 3 is arranged in the same direction as the outlet end of the air inlet pipe 101. The inlet end of the cold air acceleration pipe 3 is connected to the air supply device 6 through a connecting pipe 4. The air supply device 6 adopts a high-speed direct-drive centrifugal fan to provide high-speed airflow.

[0029] The free end of the air inlet pipe 101 is connected to the top of the steam collection hood 2 via a pipe.

[0030] In use, the steam collection hood 2 is placed over the sugarcane cooking pot. The air supply device 6 introduces high-speed airflow into the cold air acceleration pipe 3, and then blows it towards the air outlet of the air inlet pipe 101. Because the airflow from the cold air acceleration pipe 3 is fast, a low-pressure area is formed, which will carry the air in the air inlet pipe 101 into the cyclone separator 1. Therefore, a low-pressure area will also be formed in the air inlet pipe 101, thus forming a low pressure at the top outlet of the steam collection hood 2, which will draw in the steam in the area covered by the steam collection hood 2. In this way, the steam emitted from the sugarcane cooking pot is collected by the steam collection hood 2 and enters the air inlet pipe 101. After mixing with the cold air delivered by the cold air acceleration pipe 3, it is sprayed into the cyclone separator 1 together. At this time, because the cold air acceleration pipe 3 blows out a high-speed airflow, the steam carried in will also rush into the cyclone separator 1 at high speed, effectively increasing the flow rate of the steam in the cyclone separator 1, so that the cyclone separator 1 can effectively separate the moisture in the steam.

[0031] Meanwhile, in this scheme, since the high-speed airflow blown out from the cold air acceleration pipe 3 is a cold airflow (at least at room temperature, lower than the temperature of steam), after mixing with steam, it can effectively reduce the temperature of steam, which is conducive to the condensation of water in steam into water droplets, thereby effectively improving the separation effect of cyclone separator 1.

[0032] In this embodiment, a steam collection fan 201 is provided inside the steam collection hood 2. The fan sends steam into the air inlet pipe 101, which effectively improves the steam collection capacity of the steam collection hood 2 and ensures that all the steam rising from the sugarcane cooking pot can be collected by the steam collection hood 2.

[0033] In some implementations, such as Figure 4 and Figure 5 As shown, a cooling cylinder 5 is provided on the outside of the cyclone separator 1, and a cooling chamber 501 is provided between the cooling cylinder 5 and the cyclone separator 1. A cooling water inlet pipe 502 is provided at the bottom of the cooling chamber 501, and a cooling water outlet pipe 503 is provided at the top of the cooling chamber 501.

[0034] In use, the cooling water inlet pipe 502 is connected to the cooling water supply pipe, and the cooling water outlet pipe 503 is connected to the cooling water return pipe. By injecting cooling water into the cooling chamber 501 and allowing it to flow continuously, the side wall temperature of the cyclone separator 1 is effectively reduced. This makes it easier for moisture in the steam to condense on the inner wall of the cyclone separator 1 after it hits the side wall, further improving the device's ability to separate moisture from the steam.

[0035] In this embodiment, a spiral-shaped first guide vane 504 is provided inside the cooling cavity 501. The first guide vane 504 divides the internal cavity of the cooling cavity 501 into a spiral-shaped cooling channel. The lower end of the cooling channel is connected to the cooling water inlet pipe 502, and the upper end of the cooling channel is connected to the cooling water outlet pipe 503.

[0036] In this way, the cooling water in the cooling chamber 501 flows around the outer wall of the cyclone separator 1 along the cooling channel and spirals upward, effectively ensuring that all parts of the cyclone separator 1 can be cooled down well, and the side wall of the cyclone separator 1 is cooled more evenly.

[0037] In this embodiment, as Figure 6 As shown, a water tank 505 is provided on the cooling water inlet pipe 502, and the connecting pipe 4 is located inside the water tank 505. Specifically, the connecting pipe 4 passes through the water tank 505. In use, cooling water enters the water tank 505 through the cooling water inlet pipe 502 and then continues to flow into the cooling chamber 501. The airflow through the cold air acceleration pipe 3 is also cooled by the cooling water in the water tank 505 when it flows through the water tank 505, thereby effectively reducing the temperature of the high-speed airflow blown out from the cold air acceleration pipe 3, which is conducive to the condensation of moisture in the steam.

[0038] In this embodiment, the connecting pipe 4 is coiled inside the water tank 505 to increase the contact area between the connecting pipe 4 and the cooling water inside the water tank 505, so that the airflow through the cold air acceleration pipe 3 can be cooled better.

[0039] In this embodiment, as Figure 7 As shown, the connecting pipe 4 is provided with a cleaning water inlet pipe 401 on a portion of the pipe inside the water tank 505. A valve 402 is provided on the cleaning water inlet pipe 401, and the valve stem of the valve 402 passes through the water tank 505, so that the handwheel of the valve 402 is located outside the water tank 505.

[0040] Because the steam from the sugarcane cooking pot contains some sugar, some sugar will inevitably condense on the inner wall of the cyclone separator 1 after a period of use. When cleaning the inner wall of the cyclone separator 1, open valve 402 so that the cooling water in the water tank 505 can enter the connecting pipe 4 through the cleaning inlet pipe 401. The water is then carried by the high-speed airflow in the connecting pipe 4 and sprayed into the cyclone separator 1 to rinse it. This makes cleaning the inner wall of the cyclone separator 1 more convenient.

[0041] In some implementations, such as Figure 3As shown, the inner wall of the cyclone separator 1 is provided with a spiral-shaped second guide vane 102. This causes the steam entering the cyclone separator 1 to rotate along a spiral trajectory, significantly enhancing the rotation intensity of the airflow and its residence path inside the cylinder, thereby greatly improving the centrifugal separation efficiency. This structure can effectively cause the mist droplets, water droplets, and solid impurities entrained in the steam to be rapidly thrown to the cylinder wall under the enhanced centrifugal force and collect and sink along the wall surface, achieving more thorough gas-liquid (or gas-solid) separation. Compared with the existing cyclone separator 1 without guide vanes, this structure can significantly improve the separation efficiency per unit time, while reducing residual liquid adhesion and problems such as scale buildup and blockage inside the equipment. This design also facilitates rapid drainage and subsequent cleaning and maintenance of the separator, significantly improving the applicability and energy utilization efficiency of the equipment in high-hygiene environments such as food processing.

[0042] In this embodiment, an air inlet guide shroud 103 is provided on the inner side wall of the cyclone separator 1. One end of the air inlet guide shroud 103 covers the outlet of the air inlet pipe 101, and the bottom of the other end extends to the upper end of the second guide plate 102.

[0043] The air intake guide shroud 103 shapes and mixes the newly introduced steam and high-speed airflow, and guides the airflow to spiral downwards and rotate evenly along the inner wall of the cyclone separator 1, avoiding airflow erratic movement and local vortex turbulence, making the centrifugal separation field more stable, and making it easier for water droplets to be thrown towards the cylinder wall.

[0044] Example 2: Based on Embodiment 1, the difference lies in that, in this embodiment, as Figure 8 As shown, the free end of the air inlet pipe 101 is connected to the cold air acceleration pipe 3, and the air inlet pipe 101 is connected to the top of the steam collection hood 2 via a pipe. Specifically, the connection position of the pipe is located between the outlet of the cold air acceleration pipe 3 and the air inlet pipe 101. During operation, the air inlet pipe 101 is a mixing chamber for steam and high-speed airflow, which effectively improves the ability of the high-speed airflow to carry steam, which is conducive to increasing the speed at which steam enters the cyclone separator 1, thereby improving the device's ability to separate moisture.

[0045] In this embodiment, an orifice plate 301 is provided at the outlet end of the cold air accelerator pipe 3. The orifice plate 301 is provided with holes at uniform intervals. Through the orifice plate 301, the airflow ejected from the cold air accelerator pipe 3 is divided into multiple fine airflows, which effectively increases the contact area between the airflow and the steam, and further improves the ability of the high-speed airflow to carry steam.

[0046] Example 3: This application provides a method for steam diversion and collection in a sugarcane cooking pot using the steam diversion and collection device described in Embodiment 1 or 2, specifically including the following steps. S1: Cover the sugarcane cooking pot with the steam collection hood 2 to collect the boiling steam from the sugarcane cooking pot, and then transport it through the pipeline to the air inlet pipe 101 of the cyclone separator 1. S2: The air supply equipment 6 introduces cold air into the air inlet pipe 101 through the cold air acceleration pipe 3, mixes it with steam and blows it into the cyclone separator 1 together, effectively increasing the speed at which steam enters the cyclone separator 1, so that the moisture in the steam can be separated. S3: Cyclone separator 1 separates the moisture and air in the steam. The moisture is discharged from the lower end of cyclone separator 1, and the air is discharged from the upper end of cyclone separator 1.
