Description

Technical Field

[0001] This utility model belongs to the field of ethylene glycol production technology, specifically relating to a cooling device for ethylene glycol production. Background Technology

[0002] Ethylene glycol is a colorless, odorless, sweet-tasting viscous liquid with the chemical formula (CH₂OH)₂. It is the simplest diol. It is an important chemical raw material widely used in the manufacture of polyester fibers, polyester resins, humectants, plasticizers, surfactants, synthetic fibers, cosmetics, and explosives. Ethylene glycol can also be used as a solvent, antifreeze, and a raw material for the synthesis of polyester fibers.

[0003] Ethylene glycol contains two hydroxyl groups, which gives it strong polarity and makes it miscible with water and many organic solvents. However, the production of ethylene glycol is often accompanied by a large amount of heat. Because ethylene glycol is highly unstable at high temperatures, it needs to be cooled during production to prevent it from reacting to produce ethylene oxide. However, existing cooling devices usually use separate water cooling or air cooling, which affects the overall cooling efficiency during use. Utility Model Content

[0004] The purpose of this invention is to overcome the problem that existing ethylene glycol cooling devices often use separate cooling technologies, resulting in low cooling efficiency, and to provide a cooling device for ethylene glycol production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cooling device for ethylene glycol production includes a water cooling mechanism, an air cooling mechanism, and a main body. The main body is connected to the water cooling mechanism, and the air cooling mechanism is located on the inner wall of the main body. The water cooling mechanism exchanges water and heat with the ethylene glycol to cool the ethylene glycol, and the air cooling mechanism dissipates the heat generated by the water-heat exchange.

[0007] The water cooling mechanism includes a water inlet hose, the output end of which is connected to a cooling tank located inside the main body. The inner wall of the cooling tank is fixed with partition plates on the upper and lower sides, and a finned tube is connected through the two partition plates. Ethylene glycol is located around the finned tube. Condensate flows through the water inlet hose to cool the tank, and then flows through the partition plates into the finned tube to exchange water and heat with the ethylene glycol.

[0008] The partition plate is sealed to the inner wall of the cooling tank.

[0009] The water inlet hose is located above the upper partition plate, and a condensate outlet is provided at the bottom of the cooling tank, located below the lower partition plate.

[0010] The cooling tank has an inlet and an outlet on its outer wall. The inlet is located below the upper partition plate, and the outlet is located above the lower partition plate.

[0011] The cooling tank is fixedly fitted with heat dissipation fins on its outer wall.

[0012] The inlet hose is connected to a water pump at its input end.

[0013] The main body includes a main shell, a door panel is hinged to the front of the main shell, and a main base is fixedly connected to the bottom of the main shell.

[0014] The back panel of the main body shell has ventilation openings.

[0015] The air-cooling mechanism consists of several fans. The fan output end is fixed with fan blades, and the back of the fan is connected with a fixing lug. The fixing lug is fixed to the back plate of the main body shell by fixing bolts.

[0016] The fan blades are positioned corresponding to the ventilation openings.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention provides a cooling device for ethylene glycol production, comprising a water-cooling mechanism, an air-cooling mechanism, and a main body. The water-cooling mechanism includes a water inlet hose connected to a cooling tank located inside the main body. Partition plates are fixedly installed on the upper and lower inner walls of the cooling tank, with a finned tube connecting the two partition plates. Ethylene glycol is located around the finned tube. Condensate enters the cooling tank through the water inlet hose and then flows into the finned tube through the partition plates. When the condensate flows through the finned tube into the middle of the cooling tank, it exchanges heat with the ethylene glycol in the middle of the cooling tank, thereby rapidly reducing the temperature of the ethylene glycol. Due to the structural characteristics of the finned tube, it can provide a larger heat exchange area for the same length, thus enabling more efficient heat transfer, reducing energy consumption, and saving costs. An air-cooling mechanism is installed on the inner wall of the main body to dissipate the heat generated by the water-heat exchange. The combined cooling of the water-cooling and air-cooling mechanisms helps to quickly cool the ethylene glycol and improve the cooling efficiency.

[0019] Furthermore, by installing a large number of heat dissipation fins on the outer wall of the cooling tank, the overall heat dissipation area of ​​the cooling tank can be increased, thereby enhancing the overall cooling effect of the equipment.

[0020] Furthermore, the partition plate is sealed to the inner wall of the cooling tank, which will seal and isolate the condensate, preventing it from entering the middle of the cooling tank through the gap between the partition plate and the finned tube and coming into contact with the ethylene glycol.

[0037] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0038] Example 1

[0039] A cooling device for ethylene glycol production has the following structural components:

[0040] like Figures 1-6 As shown, a cooling device for ethylene glycol production includes a water cooling mechanism 1, an air cooling mechanism 2, and a main body mechanism 3, wherein the air cooling mechanism 2 is located on the inner wall of the main body mechanism 3.

[0041] The water cooling mechanism 1 includes a water pump 101, which is located on the top of the main body 3. The output end of the water pump 101 is fixedly connected to a water inlet hose 102. The output end of the water inlet hose 102 is fixedly connected to a cooling tank 103 located inside the main body 3. A condensate outlet 105 is connected to the other side wall of the cooling tank 103 opposite to the water inlet hose 102.

[0042] The inner wall of the cooling tank 103 is fixedly connected with partition plates 106 at the top and bottom. Multiple finned tubes 107 are fixedly connected through the two partition plates 106. The upper partition plate 106 is located below the water inlet hose 102, and the lower partition plate 106 is located above the condensate outlet 105.

[0043] The outer wall of the cooling tank 103 is fixedly connected with heat dissipation fins 104. A feed inlet 108 is fixedly connected to one side of the outer wall of the cooling tank 103. A discharge outlet 109 is fixedly connected to the opposite side of the outer wall of the cooling tank 103. The feed inlet 108 is located below the upper partition plate 106, and the discharge outlet 109 is located above the lower partition plate 106.

[0044] The main body 3 includes a main body shell 301, a door panel 302 is hinged to the front of the main body shell 301, a main body base 303 is fixedly connected to the bottom of the main body shell 301, and a ventilation opening 304 is provided on the back panel of the main body shell 301.

[0045] The air-cooling mechanism 2 includes a fan 201, with a fan blade 202 fixedly connected to the output end of the fan 201, and a fixing ear 203 fixedly connected to the back of the fan 201. The fixing ear 203 is fixed to the back plate of the main body shell 301 by threaded connection with the fixing bolt 204, and the fan blade 202 corresponds to the position of the ventilation port 304.

[0046] Example 2

[0047] A cooling device for ethylene glycol production operates on the following principle:

[0048] A water pump 101 is fixedly connected to an inlet hose 102, which is fixedly connected to a cooling tank 103. The water pump 101 pressurizes the condensate to ensure that the condensate can enter the cooling tank 103. Ethylene glycol enters the cooling tank 103 through the feed inlet 108. When condensate enters the cooling tank 103, it undergoes hydrothermal exchange with the ethylene glycol inside the cooling tank 103, removing heat from the ethylene glycol and cooling it down. The heated condensate flows out through the condensate outlet 105, completing a cooling cycle. The circulating condensate accelerates the cooling rate of the ethylene glycol. By installing partition plates 106 at both the upper and lower ends of the inner wall of the cooling tank 103, when condensate enters the cooling tank 103 through the water inlet hose 102, the partition plates 106 are fixedly connected to the finned tubes 107. The partition plates 106 and the inner wall of the cooling tank 103 are sealed together. Therefore, the upper partition plate 106 seals and isolates the condensate, preventing it from entering the middle of the cooling tank 103 through the gap between the partition plate 106 and the finned tubes 107 and coming into contact with the ethylene glycol. Condensate enters the finned tube 107 through the top opening. As the condensate flows through the finned tube 107 through the middle of the cooling tank 103, it exchanges heat with the ethylene glycol in the middle of the cooling tank 103, thereby rapidly reducing the temperature of the ethylene glycol. The cooled ethylene glycol is discharged from the outlet 109, while the condensate, after heat exchange, enters below the lower partition plate 106 through the bottom opening of the finned tube 107 and is discharged from the condensate outlet 105. Due to the structural characteristics of the finned tube 107, it can provide a larger heat exchange area for the same length, thus enabling more efficient heat transfer, reducing energy consumption, and saving costs. In addition, by setting a large number of heat dissipation fins 104 on the outer wall of the cooling tank 103, the overall heat dissipation area of ​​the cooling tank 103 is increased, enhancing the overall cooling effect of the equipment. Furthermore, the fan 201 is fixedly connected to the fan blade 202. By fixing the fan blade 202 to the output end of the fan 201, the fan 201 can drive the fan blade 202 to rotate and generate airflow to assist cooling, dissipate the heat generated by water heat exchange, and shorten the cooling time.
