Description

Technical Field

[0001] This utility model relates to the field of steam recovery technology, and in particular to a device for recovering and utilizing steam from sugar production. Background Technology

[0002] Steam recovery and reuse in sugar production is a technology that recovers and reuses steam generated by sugar boilers during the sugar production process. During sugar production, boilers burn fuel to generate steam for heating, evaporation, and other operations. The steam recovery and reuse device collects the steam, processes it (such as filtering impurities and separating moisture), and then returns the heat and water resources in the steam to the boiler or production process, thereby achieving energy recycling, reducing production costs, and minimizing resource consumption and environmental pollution.

[0003] In the sugar industry, efficient energy utilization and resource recycling are crucial for reducing production costs and minimizing environmental impact. Existing sugar boilers often release steam directly into the atmosphere during operation, resulting in significant heat loss and requiring the boilers to consume more fuel to maintain the required steam volume. Furthermore, existing steam recovery devices are not ideal in separating and filtering steam, leading to the recovered steam containing numerous impurities that affect the stability of subsequent sugar-making processes and product quality. Additionally, the low heat transfer efficiency during steam reheating prevents full utilization of the steam's heat energy, further wasting energy. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A sugar-making steam recovery and utilization device includes a sugar-making boiler, the top of which is hinged to a top cover, and a first horizontally arranged gas guide pipe is connected to the outside of the sugar-making boiler, the other end of which is connected to a return tank.

[0027] Example 1:

[0028] Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a sugar-making steam recovery and utilization device, including a sugar-making boiler 1. The top of the sugar-making boiler 1 is hinged to a top cover 2. A first gas guide pipe 3 arranged horizontally is connected to the outside of the sugar-making boiler 1. The other end of the first gas guide pipe 3 is connected to a return tank 4.

[0029] The sugar boiler 1 provides the heat energy required for sugar production, generating steam through fuel combustion and other methods for heating, evaporation, and other operations in the sugar production process. The top cover 2 is used to seal the sugar boiler 1, preventing heat loss and the entry of external impurities, thus ensuring the stability and safety of the sugar production process. The first steam guide pipe 3 is used to connect the sugar boiler 1 and the return tank 4, guiding the steam generated in the sugar boiler 1 into the return tank 4 to achieve initial steam transport. The return tank 4 serves as a container for initial steam treatment and distribution. Its inner wall is equipped with baffles 5 and a first filter plate 6, which can initially separate and filter the incoming steam, separating some impurities from the steam, while providing a space for subsequent steam treatment and reheating processes.

[0030] The inner wall of the reflux tank 4 is fixed with a vertically arranged baffle 5, the inner wall of the reflux tank 4 is provided with a first filter plate 6, the bottom of the reflux tank 4 is connected to a bent pipe 7, and the other end of the bent pipe 7 is connected to the inner wall of the sugar boiler 1. A reheating component 8 for reheating the moisture in the steam is provided below the reflux tank 4.

[0031] The baffle 5 can change the flow direction and path of steam in the return tank 4, increase the residence time of steam in the tank, and help to better separate moisture and impurities in the steam. The first filter plate 6 is used to filter the steam, remove solid impurities and some liquid droplets from the steam, and improve the purity of the steam. The bent pipe 7 is used to transport part of the liquid and heat separated in the return tank 4 back to the sugar boiler 1, realize the recycling of water resources, and reduce production costs. The reheating component 8 can heat the liquid in the steam through its internal structure, and at the same time, it can transport the heated liquid and the heat generated during the heating process to the sugar boiler 1.

[0032] The regenerating assembly 8 includes a housing 81 located below the reflux tank 4. A heat exchanger 82 is installed inside the housing 81. A horizontally arranged water pipe 83 is connected to one side of the housing 81, and the other end of the water pipe 83 is connected to the inner wall of the sugar boiler 1. A second air pipe 84 is connected to the top of the housing 81, and the other end of the second air pipe 84 is connected to the inner wall of the sugar boiler 1.

[0033] The housing 81 provides space for heat exchange between steam and the heat exchange medium. The heat exchanger 82 facilitates heat exchange between steam and the heat exchange medium, transferring heat from the steam to the heat exchange medium to achieve reheating. The water pipe 83 transports the water after heat exchange back to the sugar boiler 1, realizing the recycling of water resources. The second air pipe 84 transports the heat from the reheated steam back to the sugar boiler 1 to continue participating in the sugar production process, improving energy efficiency. It should be noted that the working principle of the heat exchanger 82 in this case is the same as that of the medium-temperature superheater and low-temperature superheater in a circulating fluidized bed boiler for preventing high-alkali coal slagging, as described in the authorized application number 202220323132.8. This is prior art and will not be elaborated further here.

[0034] Example 2:

[0035] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the outer side of the sugar boiler 1 is connected to a horizontally arranged feed pipe 9, the other end of which is fixed with a flange 10, and a control valve 11 is provided on the outer side of the feed pipe 9.

[0037] By using the feed pipe 9, flange 10 and control valve 11 together, the raw materials required for sugar production can be easily transported into the sugar boiler 1.

[0038] Specifically, the bottom of the sugar boiler 1 is fixed with a support leg 12, and the bottom of the sugar boiler 1 is connected to a vertically arranged discharge pipe 13, with a first valve 14 installed on the outside of the discharge pipe 13.

[0039] The support leg 12 can support the sugar boiler 1 and improve the stability of the main body. By setting the discharge pipe 13 and using it in conjunction with the first valve 14, it is easy to discharge the prepared sugar.

[0040] Specifically, the sugar boiler 1 is equipped with two sets of second filter plates 15 with symmetrical upper and lower designs, and a sealing plate 16 is fixed to the inner wall of the top cover 2, with the outer side of the sealing plate 16 fitting into the inner wall of the sugar boiler 1.

[0041] The second filter plate 15 facilitates the preliminary filtration of steam generated during the sugar-making process, removing impurities from the steam. The sealing plate 16 enhances the sealing between the top cover 2 and the sugar-making boiler 1, preventing steam leakage.

[0042] Example 3:

[0043] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0044] Specifically, the outside of the return tank 4 is connected to a horizontally arranged connecting pipe 17, and the other end of the connecting pipe 17 is provided with an air negative pressure unit body 18.

[0045] The connecting pipe 17 is used to connect the air negative pressure unit 18. The air negative pressure unit 18 creates negative pressure conditions for the return tank 4, so that steam can flow more smoothly from the sugar boiler 1 into the return tank 4, thereby improving the steam recovery efficiency. It should be noted that the working principle of the air negative pressure unit 18 in this case is the same as the working principle of the air negative pressure unit in the steam recovery and utilization device with the authorized application number 202420371819.8. It is prior art and will not be described in detail here.

[0046] Specifically, the bottom of the reflux tank 4 and the top of the bend pipe 7 are both fixed with connecting flanges 19, and the bottom of the reflux tank 4 and the top of the bend pipe 7 are connected through the connecting flanges 19.

[0047] The connecting flange 19 is used to connect the reflux tank 4 to the bent pipe 7, while ensuring the connection is secure and airtight.

[0048] Specifically, a water supply pipe 20 is connected to the outside of the bent pipe 7, and the end of the water supply pipe 20 away from the bent pipe 7 is connected to one side of the box 81. A second valve 21 is provided on the outside of the water supply pipe 20.

[0049] By setting up the water supply pipe 20 and the second valve 21 for use, it is easy to transport some of the water in the bent pipe 7 into the box 81 to participate in the reheating process.

[0050] Working Principle: When recovering and utilizing the steam generated during the sugar refining process, firstly, the raw materials required for sugar refining are supplied to the sugar boiler 1 through the cooperation of the feed pipe 9, flange 10, and control valve 11 on the outside of the sugar boiler 1. The sugar boiler 1 provides heat energy for the sugar refining process, generating steam by burning fuel for heating, evaporation, and other operations in the sugar refining process. The steam generated during the sugar refining process enters the sugar boiler 1 and first passes through two sets of second filter plates 15 with symmetrical upper and lower designs to initially filter and remove impurities from the steam. The steam then enters the return tank 4 through the first air guide pipe 3. At this time, the connecting pipe 17 connected to the outside of the return tank 4 is connected to the air negative pressure unit 18 to create negative pressure conditions for the return tank 4, allowing the steam to flow more smoothly from the sugar boiler 1 into the return tank 4, improving the steam recovery efficiency. Inside the return tank 4, the baffle 5 changes the flow direction and path of the steam, increasing the residence time of the steam in the tank, which helps to better separate moisture and impurities in the steam. At the same time, the first filter plate 6 further filters the steam, removing solid impurities and some droplets from the steam, improving the efficiency of steam recovery. The high purity of the steam allows for the separation of some liquid and heat, which is then transported back to the sugar boiler 1 via the bend pipe 7, achieving water resource recycling and reducing production costs. The water pipe 20 connected to the outside of the bend pipe 7 allows some water from the bend pipe 7 to be transported to the housing 81 to participate in the reheat process when the second valve 21 is opened. The housing 81 provides space for heat exchange between the steam and the heat exchange medium. The heat exchanger 82 transfers the heat from the steam to the heat exchange medium, achieving the purpose of reheating. The water after heat exchange is then transported back to the sugar boiler via the water guide pipe 83. 1. Water resources are recycled. The heat from the reheated steam is then transported back to the sugar boiler 1 through the second steam pipe 84 to continue participating in the sugar production process, thus improving energy efficiency. In addition, the bottom of the return tank 4 is connected to the bent pipe 7 through the connecting flange 19 to ensure the connection is firm and airtight. At the same time, the discharge pipe 13 at the bottom of the sugar boiler 1 works in conjunction with the first valve 14 to facilitate the discharge of the prepared sugar. The sealing plate 16 on the inner wall of the top cover 2 enhances the airtightness between the top cover 2 and the sugar boiler 1 to prevent steam leakage.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
