Description

Technical Field

[0001] The invention belongs to the field of cyclopentane heat exchange and air cooling metals, and in particular relates to a sewage heat exchange and air cooling device using cyclopentane. Background Art

[0002] Cyclopentane is an important organic compound that is widely used in chemical research, industrial production and life. It is mainly used as a solvent, especially in the chemical industry. It is a widely used solvent. Many products with strong odors contain it. The sewage heat exchanger is usually used in the sewage source heat pump system. The heat in the sewage is exchanged to the working medium on the other side through the heat exchanger to achieve energy transfer. This device may include various structures and designs, but its core purpose is to improve energy utilization efficiency and achieve indirect utilization of sewage. Cyclopentane is generally used as a refrigerant, and the heat in the sewage is exchanged into cyclopentane through sewage heat exchange technology. The heat in the cyclopentane is then dissipated into the environment by air cooling, thereby realizing the device of sewage heat recovery and reuse.

[0003] At present, the water temperature of refinery electric desalination wastewater is 80-90℃, which accounts for 30%-40% of the refinery saline wastewater discharge. It needs to be cooled to below 50℃ before it can be mixed with other wastewater and enter the saline wastewater treatment system for treatment. However, the traditional cooling method of this wastewater is water cooling or air cooling. Due to the large amount of water and small temperature difference, the heat exchange efficiency is low, and the heat exchange process wastes energy. Therefore, the present invention proposes a sewage heat exchange air cooling device using cyclopentane to overcome the above technical problems existing in the existing related technologies. Summary of the invention

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0010] Furthermore, the heat exchanger body is fixedly mounted to the cooling chamber via a flange, the heat flow inlet and the heat flow outlet are both fixedly mounted on a connecting tube cover, and the connecting tube cover is arranged at one end of the heat exchanger body away from the cooling chamber.

[0011] Furthermore, a partition is fixedly installed inside the connecting tube cover, and the partition divides the connecting tube cover into an upper half groove and a lower half groove.

[0012] Furthermore, a support base is fixedly installed below the heat exchanger body, and two groups of the support base are provided.

[0013] The present invention has the following beneficial effects:

[0014] 1. The present invention utilizes the high temperature pressure difference of gaseous cyclopentane, so that when the gaseous cyclopentane enters the cooling chamber, it can drive the impeller to rotate, thereby driving the rotating rod to rotate, and then driving the large gear to rotate, thereby driving four small gears and four cooling fans to rotate, so that the gaseous cyclopentane can be cooled and cooled, and finally the liquid cyclopentane is discharged from the cold flow outlet of the cylinder cover, and can be collected for secondary utilization, which greatly saves the use cost.

[0015] 2. The present invention realizes heat exchange by allowing the refinery electrically desalted wastewater to enter the heat exchanger body from the hot flow inlet, then circulate through the heat exchange tubes, and then discharge from the hot flow outlet. During this process, cyclopentane enters the heat exchanger body from the cold flow inlet and fills the inner cavity of the heat exchanger body. Rapid cooling is achieved by evaporating and absorbing heat in the heat exchanger body.

[0026] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0027] In the description of the present invention, it is necessary to understand that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention.

[0028] See also Figure 1-Figure 6 As shown, the present invention is a sewage heat exchange air cooling device using cyclopentane, comprising a heat exchanger body 1, a heat exchange tube 2 is arranged inside the heat exchanger body 1, a cold flow inlet 3 is arranged above the heat exchanger body 1, and the cold flow inlet 3 is used to add cyclopentane, a cooling chamber 4 is arranged on one side of the heat exchanger body 1, an air cooler 5 is arranged inside the cooling chamber 4, a cooling mechanism is arranged inside the air cooler 5, a cold flow outlet 6 is arranged below the cooling chamber 4, and a hot flow inlet 7 and a hot flow outlet 8 are arranged on one side of the heat exchanger body 1.

[0029] The working principle of the sewage heat exchange air cooling device using cyclopentane proposed by the present invention is that the refinery electric desalination sewage first enters the heat exchanger body 1 from the hot flow inlet 7, then passes through the heat exchange tube 2 to form a cycle, and then is discharged from the hot flow outlet 8 to achieve heat exchange. In this process, cyclopentane enters the heat exchanger body 1 from the cold flow inlet 3 and fills the inner cavity of the heat exchanger body 1. The cyclopentane evaporates and absorbs heat in the heat exchanger body 1 to achieve rapid cooling. At the same time, it becomes gas and is ejected. The ejected gaseous cyclopentane is collected and blown into the interior of the cooling chamber 4. Finally, it is cooled by the cooling mechanism inside the air cooler 5 to form liquid cyclopentane and be discharged from the cold flow outlet 6, so that it can be reused for a second time.

[0030] It is worth noting that since the boiling point of cyclopentane is about 50°C, it evaporates and absorbs heat in the heat exchanger body 1 to become a gas and is sucked into the cooling chamber 4 for cooling (the air temperature is lower than the boiling point), and is simultaneously cooled by the air cooler 5 and the cooling mechanism. Finally, the cyclopentane is cooled into a liquid and can be reused.

[0036] The working principle of the sewage heat exchange air cooling device using cyclopentane proposed by the present invention is that cyclopentane evaporates and absorbs heat to become gas in the heat exchanger body 1, and then enters the cooling chamber 4 through the air vents 22 opened in the fixed plate 9, and utilizes the high temperature pressure of the gaseous cyclopentane, so that when the gaseous cyclopentane enters the cooling chamber 4, it can drive the impeller 10 to rotate, thereby driving the rotating rod 11 to rotate, and then driving the large gear 12 to rotate. Since the large gear 12 is meshed with four small gears 13, it drives the four small gears 13 to rotate, and then drives the four cooling fans 14 to rotate, so that the gaseous cyclopentane can be cooled and cooled, and finally the liquid cyclopentane cylinder cover cold flow outlet 6 is discharged and can be collected for secondary utilization, which greatly saves the use cost.

[0037] In one embodiment, for the above-mentioned connecting tube cover 17 , a partition plate 18 is fixedly installed inside the connecting tube cover 17 , and the partition plate 18 divides the connecting tube cover 17 into an upper half groove 19 and a lower half groove 20 .

[0039] The working principle of the sewage heat exchange air cooling device using cyclopentane proposed in the present invention is that when heat exchange is performed, cyclopentane enters the interior of the heat exchanger body 1 from the cold flow inlet 3 and fills the inner cavity of the heat exchanger body 1, and then the cyclopentane is discharged from the cold flow outlet 6. During this process, the refinery electrically desalted sewage enters the interior of the connecting tube cover 17 from the hot flow inlet 7 and fills the upper half tank 19 located on the upper side of the partition 18.
