Description

Technical Field

[0001] This utility model belongs to the field of chemical concentration technology, specifically relating to an aminotetraethylene glycol concentration device. Background Technology

[0002] In the production of fine chemical products, aminotetraethylene glycol is a key intermediate, and its purity and concentration directly affect the quality of the final product. Traditional aminotetraethylene glycol concentration equipment mainly relies on a single evaporation technology, which typically involves a heating chamber. However, these traditional methods have several limitations: a single heating method often results in uneven heating, leading to low concentration efficiency, high energy consumption, and potentially prolonged production cycles; a single heating source cannot adjust its power according to actual needs, resulting in energy waste and increased production costs.

[0003] In view of the above problems, there is an urgent need for a new type of aminotetraethylene glycol concentration device that can provide a more efficient, energy-saving, and safer concentration process while ensuring product quality and reducing environmental impact. This new device should be able to adapt to different process conditions and precisely control the heating process to meet the high standards of modern chemical production. Summary of the Invention

[0004] To address the aforementioned problems, this utility model discloses an aminotetraethylene glycol concentration device with a novel structure. By combining a preheating zone and a heating chamber, the heating method becomes more uniform. The spiral pipe design extends the residence time of the material in the preheating zone, allowing for more thorough contact with the heat source and thus improving heat exchange efficiency. The gradually decreasing pipe diameter further enhances the turbulence effect, resulting in more uniform heat transfer and effectively improving preheating efficiency. The vacuum pump lowers the boiling point of aminotetraethylene glycol, enabling the material to evaporate at a lower temperature, reducing the risk of decomposition of heat-sensitive materials, while simultaneously improving evaporation efficiency and shortening the concentration cycle.

[0005] To achieve the above objectives, the specific technical solution of this application is as follows:

[0006] An aminotetraethylene glycol concentration device includes a tank with an inlet at the top, the inlet being connected to a preheating zone, and a detachable filter assembly between the inlet and the preheating zone. The outlet of the preheating zone is connected to the inlet of a heating chamber, a vacuum pump is connected above the heating chamber, a material circulation pump is connected to the bottom of the heating chamber via a circulation pipe, the material circulation pump is connected to the inlet of the heating chamber via a circulation pipe, a cooling box is connected to the bottom of the heating chamber, a detachable moisture-absorbing unit is provided on the upper part of the cooling box, and a discharge port is provided at the bottom of the cooling box.

[0007] Based on the above technical features, the preheating zone is a spiral pipe, the outer wall of which is wrapped with heating wires, and the diameter of the spiral pipe gradually decreases.

[0008] Based on the above technical features, preferably, the bottom of the heating chamber is provided with a three-way valve connecting the heating chamber, the circulation pipe and the cooling box.

[0009] Based on the above technical features, preferably, the moisture-absorbing unit adopts a stainless steel perforated shell, and is filled with silica gel or molecular sieve.

[0010] Based on the above technical features, preferably, the outer wall of the heating chamber is provided with a heat insulation layer to prevent heat loss, reduce energy consumption, and improve concentration efficiency.

[0011] Based on the above technical features, preferably, the insulation layer is a nano-aerogel.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] 1. This application combines a preheating zone and a heating chamber to make the heating method more uniform. A spiral pipe is used as the preheating zone, combined with heating wires wound on the outer wall, to achieve uniform preheating of the feed material. The spiral pipe design extends the residence time of the material in the preheating zone and makes more sufficient contact with the heat source, thereby improving the heat exchange efficiency. The gradually decreasing pipe diameter design further enhances the turbulence effect, making the heat transfer more uniform and effectively improving the preheating efficiency.

[0014] The vacuum pump connected above the heating chamber lowers the boiling point of aminotetraethylene glycol, allowing the material to evaporate at a lower temperature, reducing the risk of decomposition of heat-sensitive materials, while improving evaporation efficiency and shortening the concentration cycle.

[0015] The nano-aerogel insulation layer on the outer wall of the heater provides excellent thermal insulation performance, effectively reducing heat loss and lowering energy consumption;

[0016] The removable filter components and moisture absorption unit design simplify the cleaning and maintenance of the device, improve ease of operation, and increase production efficiency. Attached Figure Description

[0022] like Figure 1 As shown, an aminotetraethylene glycol concentration device includes a tank 1 with a feed inlet 2 at the top. The feed inlet 2 is connected to a preheating zone 3, which is a spiral pipe with heating wires wound around its outer wall. The diameter of the spiral pipe gradually decreases. The spiral pipe design extends the residence time of the material in the preheating zone, allowing for more thorough contact with the heat source and thus improving heat exchange efficiency.

[0024] The outlet of the preheating zone 3 is connected to the inlet of the heating chamber 4. A vacuum pump 6 is connected above the heating chamber 4. A material circulation pump is connected to the bottom of the heating chamber through a circulation pipe 11. The material circulation pump is connected to the inlet of the heating chamber 4 through a circulation pipe 11. A cooling box 8 is connected to the bottom of the heating chamber 4. A detachable moisture absorption unit 9 is provided on the upper part of the cooling box. A discharge port 10 is provided at the bottom of the cooling box 8.

[0025] A three-way valve 7 is located at the bottom of the heating chamber, connecting the heating chamber 4, the circulation pipe 11, and the cooling tank 8. The design of the three-way valve 7 allows the operator to flexibly control the material flow direction according to the needs of the concentration process, enabling effective switching of material between the heating chamber and the cooling tank. This precise flow control helps maintain optimal heating conditions, ensuring the uniformity and efficiency of the concentration process.

[0026] The moisture-absorbing unit 9 has a perforated stainless steel shell and is filled with silica gel or molecular sieve.

[0027] Preferably, the outer wall of the heating chamber is provided with an insulation layer 5 to prevent heat loss, reduce energy consumption, and improve concentration efficiency.

[0028] Preferably, the insulation layer 5 is a nano-aerogel.

[0029] Working principle:

[0030] The aminotetraethylene glycol concentration device of this invention removes impurities through a filtration assembly. The heating wire in the preheating zone of the spiral pipe provides uniform heat to preheat the raw material. The preheated material then enters the heating chamber, where the evaporation process is accelerated by a vacuum pump. A material circulation pump circulates the material from the bottom to the inlet of the heating chamber through a circulation pipe, ensuring that the material is repeatedly heated. The evaporated material enters the cooling box, where it is further concentrated through a cooling and dehumidification unit. Finally, the concentrated material is discharged through the outlet.
