TECHNICAL FIELD

[0001] The utility model relates to fural production technical field, concretely is the waste heat treatment equipment in fural production. BACKGROUND

[0002] In the fural production process, waste heat treatment is a vital link. The traditional fural production device often has problems such as low energy utilization efficiency and large heat loss when treating waste heat. Specifically, hydrolysis kettle, pure water evaporator and primary distillation tower and other key equipment will produce a large amount of waste heat in the running process, if these waste heat cannot be effectively utilized, not only will cause energy waste, also can have negative influence to the production environment.

[0003] In view of the above problem, the waste heat treatment equipment in the prior art is often complex in structure, inconvenient to operate, and low in heat recovery efficiency. For example, although some devices try to recover waste heat through the structure of the flow pipe, due to unreasonable design, the heat transfer efficiency is low, and the utilization of waste heat cannot be fully realized. At the same time, these devices often lack precise control means in the flow process, so that the flow path and direction of raw material liquid are not stable enough, which further affects the heat transfer and utilization efficiency.

[0004] In addition, the waste heat treatment equipment in the prior art also has defects in temperature control and flow monitoring. Due to the lack of effective temperature sensor and flow sensor, the device cannot monitor and control the change of temperature and flow in real time, so as to adjust and optimize in time according to the production demand.

[0019] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0020] like Figures 1-3As shown, the waste heat treatment structure is connected to the pure water evaporator 2, the hydrolysis kettle 1, and the primary distillation tower 3. The waste heat treatment structure includes: a pair of inlet pipes 4, a pair of heat-conducting ferrule-shaped sleeve pipes 5, a sleeve inlet cylindrical box 6, a spiral flow divider 7, a pair of U-shaped inlet pipes 84, multiple cross-shaped support blocks 9, multiple trumpet-shaped sleeve plates 10, and a transfer and feeding assembly.

[0021] Specifically, a pair of the drain pipes 4 are respectively connected to the hydrolysis vessel 1 and the pure water evaporator 2, and the pure water evaporator 2 and the primary distillation column 3. A pair of thermally conductive bushing-shaped sleeves 5 are respectively fitted onto the pair of drain pipes 4. Multiple trumpet-shaped sleeve plates 10 are respectively installed on the inner side of the pair of thermally conductive bushing-shaped sleeves 5 and the pair of U-shaped drain pipes 84. Multiple cross-shaped support blocks 9 are respectively fitted onto the pair of drain pipes 4, and the multiple cross-shaped support blocks 9 are... The components are connected to multiple horn-shaped sleeve plates 10, the sleeve guide cylindrical tube is sleeved on the pure water evaporator 2, the spiral flow divider 7 is connected to the sleeve guide cylindrical tube and the pure water evaporator 2, a pair of U-shaped flow guide tubes 84 are respectively connected to a pair of heat-conducting ferrule-shaped sleeve tubes 5, and a pair of U-shaped flow guide tubes 84 are respectively connected to the sleeve guide cylindrical box 6, and the transfer feeding assembly is connected to the hydrolysis kettle 1 and the heat-conducting ferrule-shaped sleeve tubes 5;

[0022] It should be noted that, in the above-mentioned furfural production process, the raw materials are systematically introduced into the hydrolysis reactor 1. Subsequently, the transfer and feeding assembly plays a crucial role, cleverly connecting a pair of U-shaped drainage pipes 84, a pair of thermally conductive ferrule-shaped sleeve pipes 5, a sleeve drainage cylindrical box 6, and a spiral flow divider 7 to form a highly efficient heat recovery and raw material drainage system. Through precise pressure regulation, the mixed raw material liquid is guided into this system. First, the liquid is guided to the inside of the transfer and feeding assembly, serving as the starting point of the entire drainage process. Then, under high pressure, the liquid is forcefully pushed into the thermally conductive ferrule-shaped sleeve pipes 5; the thermally conductive ferrule-shaped sleeve pipes 5 not only guide the liquid flow but also cleverly recover the heat dissipated by the drainage pipes 4. This heat, which might otherwise have been lost to the environment, is now effectively utilized, improving the energy efficiency of the entire production process. Subsequently, the raw material water, guided by the thermally conductive ferrule-shaped sleeve pipes 5, continues to flow into the inside of the U-shaped drainage pipes 84. With its unique shape and structure, the U-shaped drainage tube 84 smoothly guides the raw material liquid to the inside of the set of drainage cylindrical tubes. Inside the set of drainage cylindrical tubes, the spiral diverter 7 plays a crucial role in unidirectional flow guidance. It fits tightly with the inside of the set of drainage cylindrical tubes, ensuring that the liquid flows along a predetermined path and direction, further improving heat transfer and utilization efficiency. Finally, through another U-shaped drainage tube 84 on the set of drainage cylindrical box 6, the raw material liquid is guided to the inside of another heat-conducting ferrule-shaped set of tubes 5. Here, the heat-absorbing liquid undergoes further treatment and preparation, and is finally guided back to the inside of the hydrolysis reactor 1, providing strong support for the subsequent furfural production process.

[0023] like Figures 1-3 As shown, the transfer and loading assembly includes: a transfer cylindrical box 11, a liquid-drawing hydraulic push rod 12, a liquid-drawing negative pressure disc 13, a negative pressure ring rubber ring 14, and a three-way valve 15.

[0025] It should be noted that, as described above, the extension and retraction of the hydraulic push rod 12 inside the transfer cylindrical box 11 drives the negative pressure disk 13 on the push end of the hydraulic push rod 12 to move up and down stably. The negative pressure disk 13 drives the negative pressure ring 14 on it, and the negative pressure ring 14 moves up and down stably along the inner side of the transfer cylindrical box 11. At the same time, the gas flow is controlled by the three-way valve 15.
