Description

Technical Field

[0001] This utility model relates to the field of deodorization tower technology, specifically to a device for recovering and reusing waste heat from high-temperature steam in a deodorization tower. Background Technology

[0002] Deodorization towers utilize the fact that small-molecule odorous organic compounds in oils are more volatile than triglycerides under high temperature and negative pressure. When water vapor passes through the odorous oil, it becomes saturated with the volatile odor components and escapes according to their partial pressure ratio, thus achieving the purpose of deodorization. Edible oils require deodorization towers for processing during production.

[0003] Deodorization towers generate high-temperature steam during operation. However, existing deodorization towers are inefficient at utilizing the waste heat from this steam, failing to provide sufficient heat for the edible oil to be deodorized. This necessitates a slow heating process for the edible oil during deodorization, significantly reducing the efficiency of the deodorization process. To address this issue, we propose a high-temperature steam waste heat recovery and reuse device for deodorization towers. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature steam waste heat recovery and reuse device for deodorization towers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature steam waste heat recovery and reuse device for deodorization towers, comprising:

[0006] The deodorization tower body has an installation base fixedly installed on its outer wall. A preheating box is fixedly installed on the top wall of the installation base. An oil storage tank is fixedly installed inside the preheating box. A steam pipe is fixedly installed at the top of the deodorization tower body. A diverter seat is fixedly installed at the end of the steam pipe away from the deodorization tower body. A first spiral heat-conducting pipe and a second spiral heat-conducting pipe are fixedly installed on the diverter seat. The first spiral heat-conducting pipe is sleeved on the outer wall of the oil storage tank. The second spiral heat-conducting pipe is installed in the inner cavity of the oil storage tank. The ends of both the first and second spiral heat-conducting pipes away from the diverter seat extend to the outside of the preheating box and are fixedly installed on a manifold seat. An exhaust pipe is fixedly installed on the manifold seat.

[0007] Preferably, an oil injection pipe is fixedly installed on the top wall of the preheating box, and an oil discharge pipe is fixedly installed on the bottom wall of the preheating box. The end of the oil discharge pipe away from the preheating box is fixedly installed on the deodorization tower body. Solenoid valves are fixedly installed on both the oil injection pipe and the oil discharge pipe.

[0008] Preferably, a heat insulation pad is fixedly installed on the inner wall of the preheating box.

[0009] Preferably, the oil storage tank is made of a thermally conductive material.

[0010] Preferably, a check valve is fixedly installed at the end of both the first spiral heat pipe and the second spiral heat pipe near the manifold.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In use, when the deodorizing tower body is deodorizing, the high-temperature steam generated can be introduced into the distribution seat through the steam pipe, and then into the first spiral heat-conducting pipe and the second spiral heat-conducting pipe respectively. Finally, it is discharged through the exhaust pipe. When the high-temperature steam passes through the first spiral heat-conducting pipe, it can conduct heat to the outer wall of the oil storage tank to preheat the edible oil to be deodorized. When the high-temperature steam passes through the second spiral heat-conducting pipe, it can conduct heat to the edible oil in the inner cavity of the oil storage tank to preheat the edible oil to be deodorized. This realizes the utilization of the waste heat of the high-temperature steam of the deodorizing tower, which greatly reduces the heating time required for the edible oil to be deodorized during the deodorization process and improves the working efficiency of the edible oil deodorization process.

[0013] 2. This utility model, by setting a first spiral heat-conducting pipe on the outer wall of the oil storage tank and a second spiral heat-conducting pipe in the inner cavity of the oil storage tank, enables simultaneous preheating from both inside and outside when using waste heat from steam to preheat the edible oil to be deodorized, greatly improving the uniformity of preheating and the preheating effect of the edible oil.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a high-temperature steam waste heat recovery and reuse device for deodorization towers, comprising:

[0020] The deodorization tower body 1 has an installation base 2 fixedly installed on its outer wall. A preheating box 3 is fixedly installed on the top wall of the installation base 2.

A diversion seat 6 is fixedly installed at the end of the steam pipe 5 away from the deodorization tower body 1. A first spiral heat-conducting pipe 7 and a second spiral heat-conducting pipe 8 are fixedly installed on the diversion seat 6. The first spiral heat-conducting pipe 7 is sleeved on the outer wall of the oil storage tank 4. The second spiral heat-conducting pipe 8 is installed in the inner cavity of the oil storage tank 4. The ends of the first spiral heat-conducting pipe 7 and the second spiral heat-conducting pipe 8 away from the diversion seat 6 both extend to the outside of the preheating box 3 and are fixedly installed with a manifold 9. An exhaust pipe 10 is fixedly installed on the manifold 9.

[0021] An oil injection pipe 11 is fixedly installed on the top wall of the preheating box 3, and an oil discharge pipe 12 is fixedly installed on the bottom wall of the preheating box 3. The end of the oil discharge pipe 12 away from the preheating box 3 is fixedly installed on the deodorization tower body 1. Solenoid valves 13 are fixedly installed on both the oil injection pipe 11 and the oil discharge pipe 12. The oil injection pipe 11 is used to inject the edible oil to be deodorized into the oil storage tank 4, and the oil discharge pipe 12 is used to add the preheated edible oil into the inner cavity of the deodorization tower body 1.

[0022] A heat insulation pad 14 is fixedly installed on the inner wall of the preheating box 3. The heat insulation pad 14 can prevent heat from escaping, so that the preheating box 4 has a heat preservation effect.

[0023] The oil storage tank 4 is made of heat-conducting material, which facilitates the first spiral heat-conducting pipe 7 to conduct heat to the edible oil in the oil storage tank 4.

[0024] Both the first spiral heat pipe 7 and the second spiral heat pipe 8 are fixedly installed with a check valve 15 at one end near the manifold 9. The check valve 15 can prevent steam backflow.

[0025] Working principle: When in use, the edible oil to be deodorized can be added to the oil storage tank 4 through the oil injection pipe 11. When the deodorization tower body 1 is performing deodorization, the high-temperature steam generated can be introduced into the distribution seat 6 through the steam pipe 5, and then into the first spiral heat conduction pipe 7 and the second spiral heat conduction pipe 8 respectively. Finally, it is discharged through the exhaust pipe 10. When the high-temperature steam passes through the first spiral heat conduction pipe 7, it can conduct heat to the outer wall of the oil storage tank 4 to preheat the edible oil to be deodorized. When the high-temperature steam passes through the second spiral heat conduction pipe 8, it can conduct heat to the edible oil in the inner cavity of the oil storage tank 4 to preheat the edible oil to be deodorized. This realizes the utilization of the waste heat of the high-temperature steam of the deodorization tower, which greatly reduces the heating time required for the edible oil to be deodorized during the deodorization process and improves the working efficiency of the edible oil deodorization process.
