Description

Technical Field

[0001] This utility model belongs to the field of organic heat carrier treatment technology, specifically relating to a device for removing light components (such as low-boiling-point substances, moisture, volatile organic compounds, etc.) from an organic heat carrier. Background Technology

[0002] A light component removal device is a piece of equipment used to separate light components from a mixture, commonly found in chemical, petroleum, and other fields. Its core function is to separate light components (such as low-boiling-point substances, moisture, volatile organic compounds, etc.) from the mixture through physical means, thereby improving product purity.

[0003] Traditional light component separation devices suffer from problems such as low separation efficiency, high energy consumption, and complex operation. During separation, the light components, normal organic heat carriers, and heavy components are separated by manually switching valve groups, which leads to large human control errors and requires continuous monitoring by workers. This results in poor precision in light component separation and waste of some normal organic heat carriers that are separated along with the light components. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a device for removing light weights from organic heat carriers, which can improve the accuracy of light weight removal and reduce waste, in light of the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a device for removing light components from an organic heat carrier, comprising:

[0006] The light-removal reactor has a light-removal input pipeline connected to its upper part for inputting the organic heat carrier to be treated, and a light-removal output pipeline connected to its bottom for outputting the organic heat carrier after light-removal. The light-removal input pipeline is equipped with a first valve for controlling the flow rate, and the light-removal output pipeline is equipped with a second valve for controlling the flow rate.

[0007] The light component tank has its upper inlet connected to the top outlet of the light component removal vessel via a light component pipeline, so that the light components in the light component removal vessel can be collected into the light component tank. The light component pipeline is equipped with a cooler for reducing the temperature of the light components and a third valve for controlling the flow rate. The bottom of the light component tank is connected to a light component output pipeline for outputting the light components, and the light component output pipeline is equipped with a fourth valve for controlling the flow rate.

[0008] A vacuuming device, the vacuuming port of which is connected to the light component removal vessel and the light component tank;

[0009] Its characteristic is that it also includes:

[0010] Temperature sensor used to detect the temperature inside the light-duty removal reactor;

[0011] The controller has its input terminal connected to the temperature sensor and its output terminal connected to the first valve, second valve, third valve, fourth valve and vacuum device mentioned above. It is used to control the operation of each valve and the vacuum device according to the signal output by the temperature sensor.

[0012] The aforementioned organic heat transfer fluid can be mineral oil, synthetic oil, etc.

[0013] The light-removal input pipeline and light-removal output pipeline of this invention can be directly connected to the user equipment to remove light-removal substances from the organic heat carrier in the equipment, without the need to install a separate storage tank.

[0014] Before removing light components, the flash evaporation temperature of the organic heat carrier to be treated is simulated through experiments. Then, the distillation temperature under actual vacuum is set on the light component removal device. During the light component removal process, the controller controls the operation of the entire light component removal device based on the signal output by the temperature sensor. This includes, but is not limited to, the flow rate of the organic heat carrier to be treated entering the light component removal vessel, the flow rate of the light component removed organic heat carrier output from the bottom of the light component removal vessel, the flow rate of the light component output from the top of the light component removal vessel, the flow rate of the light component output from the bottom of the light component tank, and the vacuum degree in the light component removal vessel and the light component tank. This ensures that the light component in the organic heat carrier is automatically output after separation, improving the separation accuracy and avoiding the waste caused by the normal and useful organic heat carrier being removed along with the light component.

[0015] Meanwhile, this utility model eliminates the need for manual monitoring and operation, reducing errors caused by human control and lowering labor costs.

[0016] Preferably, the temperature sensor is a PT100 platinum resistance thermometer, and it is distributed at multiple points within the light-weight removal reactor. This enables multi-point temperature detection, further improving the separation accuracy. The multi-point distribution includes, but is not limited to, the temperature sensors being arranged at intervals along the vertical direction within the light-weight removal reactor.

[0017] Preferably, the cooler includes an air cooler and a first water cooler, with the air cooler located upstream of the first water cooler along the flow direction of the light component.

[0018] Preferably, the vacuum pumping device includes:

[0019] A water ring vacuum pump, wherein the inlet of the water ring vacuum pump is connected to the outlet of the water ring vacuum pump through a vacuum water circulation pipeline;

The cold medium inlet of the second water cooler is connected to an external water source, and the cold medium outlet of the second water cooler is connected to the cold medium inlet of the first water cooler via a cold medium pipeline. That is, the external water source first exchanges heat with the cooling water in the vacuum water circulation pipeline before flowing to the first water cooler to cool and exchange heat on the light components. The water source after exchanging heat with the light components can be discharged directly or cooled in a cooling tower and then recycled.

[0022] Furthermore, the bottom outlet of the vacuum buffer tank is connected to the light component output pipeline, and a fifth valve is provided on the connecting pipeline, which is connected to the controller.

[0023] Preferably, the light-removed output pipeline is provided with a first pump body for extracting the light-removed organic heat carrier, and the first pump body is located downstream of the second valve along the flow direction of the light-removed organic heat carrier.

[0024] In this invention, a pump body is not required on the light-light removal input pipeline; the organic heat carrier to be treated can be input into the light-light removal reactor using the pressure of the user equipment itself.

[0025] Preferably, the light component output pipeline is provided with a second pump body for extracting the light component, and the second pump body is located downstream of the fourth valve along the flow direction of the light component.

[0026] In the above embodiments, preferably, both the light component removal vessel and the light component tank are equipped with level sensors, which are connected to the controller to control the opening and closing of each valve based on the liquid level.

[0027] Preferably, both the light component removal vessel and the light component tank are equipped with pressure sensors for detecting internal pressure, and the pressure sensors are connected to the controller.

[0028] Compared with the prior art, the advantages of this utility model are as follows: The temperature sensor and controller of this utility model allow for the simulation of the flash evaporation temperature of the organic heat carrier to be treated before light component removal, and then the distillation temperature under actual vacuum is set on the light component removal device. During the light component removal process, the controller controls the operation of the entire light component removal device according to the signal output by the temperature sensor, including but not limited to the flow rate of the organic heat carrier to be treated entering the light component removal vessel, the flow rate of the light component removed organic heat carrier output from the bottom of the light component removal vessel, the flow rate of the light component output from the top of the light component removal vessel, the flow rate of the light component output from the bottom of the light component tank, and the vacuum degree in the light component removal vessel and the light component tank. This ensures that the light component in the organic heat carrier is automatically output after separation, improving the separation accuracy and avoiding the waste caused by the normal and useful organic heat carrier being removed along with the light component.

[0029] Meanwhile, this utility model eliminates the need for manual monitoring and operation, reducing errors caused by human control and lowering labor costs. Attached Figure Description

The segmented heating jacket is set with a gradient temperature according to the difference in boiling points of the components (e.g., 200℃ for the light component zone → 240℃ for the normal component zone → 280℃ for the recombinant zone).

[0034] The upper inlet of the light component tank 3 is connected to the top outlet of the light component removal vessel 1 via a light component pipeline 31, so that the light components in the light component removal vessel 1 can be collected into the light component tank 3.

The light component outlet line 32 can be connected to downstream containers such as light component collection tanks.

[0039] Before removing light components, the flash evaporation temperature of the organic heat carrier to be treated is simulated through experiments. Then, the distillation temperature under actual vacuum is set on the light component removal device. During the light component removal process, the controller controls the operation of the entire light component removal device based on the signals output by the temperature sensor, pressure sensor, and liquid level sensor.
