Description

Technical Field

[0001] This utility model relates to the field of storage tank heating technology, and in particular to a combined storage tank high-efficiency water hammer-free heater. Background Technology

[0002] In the chemical, petroleum, and food industries, many materials need to be kept at a certain temperature and heated before storage and use to reduce viscosity and facilitate transportation and handling. Therefore, storage tanks with heating functions are widely used. Currently, using steam as a heat source to heat the materials in the storage tank is a common and mature technology.

[0003] Existing steam-heated storage tanks use coils and serpentine tubes as heat exchange elements inside the tank. When high-temperature steam flows through these pipes, it releases latent heat to the pipe wall, and then transfers the heat to the material inside the tank through the pipe wall. However, during this process, the steam condenses into liquid water, i.e., condensate, due to the release of heat.

[0004] In some existing designs, due to unreasonable pipe structure design and poor drainage, condensate accumulates in low-lying areas and horizontal sections of the heat exchange pipes. On the one hand, the accumulated condensate layer creates thermal resistance, severely hindering the contact between subsequent steam and the pipe wall, significantly reducing heat exchange efficiency, leading to prolonged heating time and increased energy consumption. On the other hand, the high-speed flowing steam interacts with the accumulated condensate inside the pipe, creating water hammer and water surge phenomena, generating huge impact forces and noise. This not only causes serious damage to pipes, valves, and connections, but also poses significant safety hazards.

[0005] Therefore, this utility model proposes a combined storage tank high-efficiency water hammer-free heater to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of low heat exchange efficiency and water hammer hazard caused by condensate accumulation in existing steam-heated storage tanks, this utility model aims to provide a combined high-efficiency water hammer-free heater for storage tanks with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a combined high-efficiency water hammer-free heater for storage tanks, including: a support column, a ring plate, a tank body, a feed inlet, a material cover, and a discharge outlet, as well as an installation plate, a heating pipe, a heat sink, a drain pipe and a drain valve disposed inside the tank body, and a steam inlet and a steam outlet disposed outside the tank body.

[0008] The heating element has a branch pipe at the top and a branch pipe at the bottom.

[0009] Furthermore, the steam inlet and steam outlet are fixedly connected to the top of the left and right sides of the tank body, respectively. The mounting plate is installed on the front and rear sides of the inner wall of the tank body. Multiple heating tubes are fixedly connected between the mounting plates on the front and rear sides. The heat sink is fixedly connected to the outer wall of the heating tube. The branch pipes at the top of the heating tube are connected to the steam inlet and steam outlet, respectively.

[0011] Preferably, a gasket is installed between the bolt and the material cover, and a gasket is also installed between the nut and the feed port. By setting gaskets on both the upper and lower sides of the fastening connection, a double sealing barrier can be formed, which greatly improves the sealing performance of the feed port and effectively prevents material leakage and pressure loss.

[0012] Preferably, a discharge valve is fixedly connected to the left end of the discharge port. By setting the discharge valve, the timing and flow rate of material discharge after heating can be easily controlled.

[0013] Preferably, it also includes a temperature display and a temperature sensor. The temperature display is fixedly connected to the top of the tank, and the temperature sensor is fixedly connected to the bottom of the temperature display and installed on the inner top of the tank. This integrated temperature monitoring device can reflect the temperature inside the tank in real time and intuitively, providing data support for precise control of the heating process.

[0014] Preferably, there are two ring plates, and the support column supports the tank body through the ring plates. This structural design makes the supporting force evenly distributed at the bottom of the tank body, which enhances the stability of the overall structure.

[0015] Preferably, the steam inlet and the steam outlet form a steam pipe, which serves as the input and output channel for the heat source, providing a continuous steam flow to the internal heating system.

[0016] Preferably, the drain pipe is used to drain the condensate formed after the heat is released in the heating pipe, and the branch pipe at the top of the heating pipe is used to guide the incompletely condensed steam to the steam outlet. This steam-water separation passage design is the core structure for achieving water hammer-free heating.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 4 This utility model provides a combined high-efficiency water-hammer-free heater for storage tanks, aiming to solve the problems of low heat exchange efficiency and water hammer caused by steam condensate accumulation in existing storage tank heating devices, which leads to pipe vibration damage. Figure 1 and Figure 2As shown, a combined storage tank high-efficiency water-hammer-free heater includes a support column 1 and ring plates 2 fixedly connected to the top of the support column 1. A tank body 3 is mounted on the top of the two ring plates 2. The support column 1 provides stable support to the tank body 3 through the ring plates 2. The inner arc surface of the ring plates 2 conforms to the shape of the outer bottom wall of the tank body 3 to effectively distribute gravity. A feed inlet 4 is fixedly connected to the top left side of the tank body 3. The feed inlet 4 serves as a material entry channel; the substance to be stored and heated enters the interior of the tank body 3 through the feed inlet 4. The top of the feed inlet 4 is covered. A material cover 5 is provided, and bolts 6 are slidably connected to the inside of the material inlet 4. Nuts 7 are threaded onto the bottom of the bolts 6, and gaskets 8 are installed between the bolts 6 and the material cover 5, and between the nuts 7 and the material inlet 4. These fasteners work together to achieve an efficient seal at the material inlet 4. A discharge port 9 is fixedly connected to the bottom left side of the tank body 3, and a discharge valve 10 is fixedly connected to the left end of the discharge port 9. The discharge valve 10 is used to block and control the outflow of the stored material inside the tank body 3. The top of the left and right sides of the tank body 3 are respectively fixedly connected to… The tank 3 is equipped with a steam inlet 11 and a steam outlet 12, which together form a steam flow pipeline for supplying heating steam into the tank body 3. Mounting plates 15 are installed on both the front and rear sides of the inner wall of the tank 3, serving as a fixed base. Multiple heating pipes 13 are fixedly connected between the front and rear mounting plates 15. The heating pipes 13 are arranged side-by-side at intervals along the width of the tank 3. Heat dissipation fins 14 are fixedly connected to the outer wall of each heating pipe 13, and the heat from the steam inside the heating pipes 13 is transferred to the heat dissipation fins 14. The heating pipe 13 is distributed around the inside of the tank 3 and heats the material stored inside the tank 3 efficiently. The bottom of the heating pipe 13 is provided with a branch pipe and connected to a drain pipe 16. The bottom end of the drain pipe 16 extends through the bottom wall of the tank 3 to the outside of the tank 3. A drain valve 17 is fixedly connected to the bottom of the drain pipe 16. A temperature display 18 is fixedly connected to the top of the tank 3. A temperature sensor 19 is fixedly connected to the bottom of the temperature display 18. The temperature sensor 19 is installed on the top inner side of the tank 3 and is used to detect the temperature inside the tank 3.

[0030] Please refer to Figure 3 and Figure 4To address the aforementioned technical issues of heat exchange efficiency and water hammer, the core of the combined tank high-efficiency water hammer-free heater lies in the coordinated design of the steam passage and condensate drainage structure. The top of each heating tube 13 is equipped with a branch pipe connecting to all heating tubes 13, and these branch pipes are connected to both the steam inlet 11 and the steam outlet 12. This design ensures that high-temperature steam smoothly enters from the steam inlet 11 and is evenly distributed to the interior of each heating tube 13, while allowing incompletely condensed exhaust steam to flow through the top branch pipes to the steam outlet 12 for discharge, forming a complete steam circulation loop. Similarly, the bottom of each heating tube 13 is equipped with a branch pipe, specifically designed to connect to the drain pipe 16. This bottom-connected design utilizes the physical property of condensate sinking naturally under gravity, allowing condensate generated during heating to automatically collect at the bottom branch pipe and flow into the drain pipe 16. A drain valve 17 is installed at the bottom of the drain pipe 16, allowing the accumulated condensate to be promptly discharged from the outside of the tank 3 by opening the drain valve 17. This effectively prevents condensate from accumulating in the heating tube 13 and causing water hammer, and ensures that the subsequently entering steam can fully contact the tube wall for efficient heat exchange. To further improve heat exchange efficiency, heat sinks 14 are tightly fixed to the outer wall of the heating tube 13. The heat sinks 14 greatly increase the contact area between the heating tube 13 and the material inside the tank 3, allowing heat to be transferred to the material inside the tank 3 more quickly and evenly. A temperature sensor 19 is installed on the inner top of the tank 3 and monitors the temperature changes inside the tank 3 in real time. The detected temperature data is transmitted to the temperature display 18 on the top of the tank 3 for intuitive display, so that the operator can adjust the steam inlet 11 and the opening and closing of the drain valve 17 according to the real-time temperature feedback, thereby achieving precise control of the internal temperature of the tank 3. For the sealing structure of the feed inlet 4, the bolt 6 passes through the upper gasket 8, the material cover 5, the feed inlet 4 and the lower gasket 8 in sequence and is then fastened to the nut 7. The double-layer gasket 8 can fill the tiny gaps when compressed, ensuring excellent sealing performance at the feed inlet 4.

[0031] As a preferred embodiment, in order to achieve a more stable and mechanically compatible support for the tank 3, two ring plates 2 are fixedly connected to the top of the support column 1. The inner arc surface of the two ring plates 2 is designed as a curved surface structure that fits perfectly with the shape of the outer bottom wall of the tank 3. This surface contact support method can distribute the weight of the tank 3 and the internal material more evenly than point contact, and prevent the bottom of the tank 3 from deforming due to concentrated force.

[0032] As another preferred embodiment, in order to improve the rationality of the layout of the heating tubes 13 and the uniformity of heat exchange, multiple heating tubes 13 are arranged side by side and spaced apart between the mounting plates 15 on the front and rear sides along the width direction of the tank body 3. This side by side and spaced arrangement not only ensures that there are enough heating tubes 13 to provide the required heat, but also leaves appropriate gaps between the heating tubes 13 so that the material in the tank body 3 can flow in the gaps. This not only improves the overall heat conduction efficiency, but also facilitates the subsequent inspection and cleaning of the heat sink 14 on the outer wall of the heating tubes 13.

[0033] As another preferred embodiment, in order to ensure that the condensate can be discharged smoothly and completely from the tank 3, the bottom end of the drain pipe 16 is designed to penetrate the bottom wall of the tank 3 and extend to the outside of the tank 3. This through structure directly connects the condensate collection area at the bottom of the heating pipe 13 with the external environment, eliminating any dead corners that could lead to water accumulation. With the drain valve 17 installed at the bottom of the drain pipe 16, the operator can easily control the discharge of condensate from the outside of the tank 3.

[0034] As another preferred embodiment, in order to enhance the sealing reliability at the feed inlet 4 and prevent the material from corroding the fasteners, a gasket 8 is installed between the bolt 6 and the cover 5, and a gasket 8 is also installed between the nut 7 and the feed inlet 4. This double sealing structure with gaskets 8 on both the upper and lower sides of the connection can form a tighter sealing interface when the bolt 6 is tightened, effectively blocking the leakage path of gas and liquid inside the tank 3.

[0035] Working principle: Before material storage and heating operations, the material to be heated is first injected into the tank 3 through the feed inlet 4 at the top of the tank 3. After the injection is completed, the material cover 5 is placed over the opening of the feed inlet 4. Then, multiple bolts 6 are sequentially inserted through the upper gasket 8, the material cover 5, the reserved hole of the feed inlet 4, and the lower gasket 8, and are threaded and tightened with the nut 7 at the bottom of the bolts 6. Through the covering of the material cover 5 and the tightening force of the bolts 6 and the nut 7, the upper and lower gaskets 8 are fully compacted, thereby achieving a reliable seal of the feed inlet 4 and preventing material overflow and heat loss during the heating process. The entire tank 3 is supported by the inner arc surface of the two ring plates 2 through the outer wall at the bottom. The ring plates 2 are fixedly connected to the top of the support column 1, thus forming a stable support structure.

[0036] When the heating operation begins, high-temperature steam generated by an external steam source enters through steam inlet 11. Since steam inlet 11 is connected to the branch pipe at the top of heating pipe 13, the steam will smoothly flow into the interior of multiple heating pipes 13 fixed between the front and rear mounting plates 15. Inside the heating pipe 13, the high-temperature steam exchanges heat with the pipe wall, and the heat is conducted through the pipe wall to the heat sink 14 fixed on the outer wall of the heating pipe 13. Due to its huge surface area, the heat sink 14 greatly improves the heat exchange efficiency with the material inside the tank 3, so that the heat can be transferred to the material quickly and evenly, thereby achieving efficient heating. During the heat transfer process, some of the exhaust steam that is not completely condensed will continue to flow in the branch pipe at the top of the heating pipe 13 and eventually converge to the steam outlet 12 for discharge, completing the steam flow cycle.

[0037] While the steam releases heat in the heating tube 13 and heats the material, the steam itself will condense into liquid condensate due to cooling. Due to gravity, the condensate will fall along the inner wall of the heating tube 13 and collect in the branch pipe at the bottom of the heating tube 13. The branch pipe at the bottom of the heating tube 13 is connected to the drain pipe 16, so the condensate will flow into the drain pipe 16. The operator can open the drain valve 17 installed at the bottom of the drain pipe 16 as needed to completely drain the accumulated condensate from the heating system of the tank 3. This design, which separates the steam circuit and the water circuit in physical space and drains the water in time, fundamentally avoids the accumulation of condensate in the steam pipe, eliminates the water hammer phenomenon caused by high-speed steam pushing the accumulated water to hit the pipe and causing vibration and noise, ensures the safety and stability of the heating process, and also ensures the heat exchange space of the subsequent steam and maintains the high efficiency performance of the heater.

[0038] Throughout the heating process, the temperature sensor 19 installed on the top of the inner side of the tank 3 monitors the temperature of the material inside the tank 3 in real time and transmits the detected temperature signal to the temperature display 18 fixed on the top of the outer side of the tank 3 for digital display. The operator can intuitively observe the real-time temperature and adjust the valve opening of the steam inlet 11 according to the process requirements to control the steam intake, thereby accurately controlling the final temperature of the material. When the material is heated and needs to be removed, simply open the discharge valve 10 fixed on the left end of the discharge port 9, and the heated material will flow out smoothly through the discharge port 9 under the action of gravity.
