Description

Technical Field

[0001] The invention belongs to the field of oxygen production equipment, and in particular relates to a heat energy recovery cabin-type oxygen production equipment for supplying hot water. Background Art

[0002] Pressurized adsorption vacuum desorption oxygen production equipment selectively adsorbs oxygen and nitrogen in the air through molecular sieves, and desorbs the molecular sieves under vacuum conditions to produce oxygen in a cycle. There are many types of equipment in the oxygen production equipment. Before use, each device needs to be transported to the oxygen production site for assembly. Sufficient installation and commissioning time must be reserved. The installation and commissioning cycle is long and cumbersome. On the other hand, the oxygen produced by the oxygen production equipment usually needs to be compressed by a compressor and stored in an oxygen storage tank for use at any time. A large amount of heat will be generated during the compression of oxygen. In the traditional oxygen production process, the heat generated by the compressor is usually released directly to the external environment with the help of a circulation system. The heat cannot be collected and utilized, resulting in a waste of resources. Summary of the invention

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0026] Specific implementation examples Figure 1-4 As shown, this embodiment relates to a heat recovery cabin-type oxygen production equipment for supplying hot water, including an oxygen production main unit, an air compressor 1 and an oxygen storage tank 2, and also includes a heat recovery unit, the heat recovery unit includes a heat exchange barrel 3, a heat exchange pipe 4, a heat storage pipe 5 and an energy storage insulation barrel 6, the heat exchange pipe 4 and the heat storage pipe 5 are respectively arranged in the heat exchange barrel 3, the heat exchange pipe 4 is connected to the cooling pipe of the air compressor 1 to form a first circulation loop 7, the heat storage pipe 5 is connected to the energy storage insulation barrel 6, and the heat storage pipe 5 is provided with a liquid infusion pipe 8 connected to the outside of the heat exchange barrel 3, and the energy storage insulation barrel 6 is provided with a liquid outlet pipe 9 connected to the outside of the heat exchange barrel 3. The heat exchange barrel 3 is provided with a first heat transfer oil, the heat exchange pipes 4 are respectively provided with a second heat transfer oil, and the heat storage pipe 5 is provided with water.

[0027] The air compressor 1 compresses the oxygen obtained by the oxygen generator, and the compressed oxygen is stored in the oxygen storage tank 2. A cooling pipe is provided in the air compressor 1, and the cooling pipe is connected to the heat exchange pipe 4 to form a first circulation loop 7. The second heat transfer oil in the heat exchange pipe 4 circulates in the first circulation loop 7. A large amount of heat is released in the process of compressing oxygen by the air compressor 1. The high-temperature second heat transfer oil in the cooling pipe flows along the first circulation loop 7 to the heat exchange pipe 4 in the heat energy exchange barrel 3. The first heat transfer oil in the heat energy exchange barrel 3 absorbs the heat of the second heat transfer oil in the heat exchange pipe 4, and the temperature of the second heat transfer oil in the heat exchange pipe 4 decreases. The second heat transfer oil with a lower temperature in the heat exchange pipe 4 returns to the cooling pipe to cool the air compressor 1; the temperature of the first heat transfer oil in the heat energy exchange barrel 3 increases, and the heat storage pipe 5 is heated, and the water temperature in the heat storage pipe 5 increases, and the water in the heat storage pipe 5 is discharged to the energy storage insulation barrel 6 for storage. The liquid replenishing pipe 8 replenishes water into the heat storage pipe 5, so that the water with increased temperature in the heat storage pipe 5 is replaced by water with lower temperature to continue to absorb heat. The heat storage pipe 5 absorbs the heat in the heat energy exchange barrel 3, so that the first heat transfer oil in the heat energy exchange barrel 3 maintains a low temperature, thereby achieving sufficient cooling of the heat exchange tube 4. The hot water in the heat storage pipe 5 is stored in the energy storage insulation barrel 6 for use, effectively reducing energy waste.

[0028] The first heat transfer oil and the second heat transfer oil have a fast heat transfer speed, and can quickly transfer the heat in the air compressor 1 to the heat exchange barrel 3, thereby reducing the temperature of the working environment of the air compressor 1 and preventing parts from being damaged by heat.

[0029] Preferably, a water inlet interlayer 301 is provided on the heat exchange barrel 3 , and the heat storage tube 5 and the liquid replenishment tube 8 are respectively connected to the water inlet interlayer 301 , and the liquid replenishment tube 8 fills water into the water inlet interlayer 301 , and the water in the water inlet interlayer 301 is diverted to each liquid storage tube 5 .

[0030] Furthermore, the energy storage and insulation barrel 6 is arranged in the heat energy exchange barrel 3, and the water in the heat storage pipe 5 absorbs the heat in the heat energy exchange barrel 3 and becomes hot water stored in the energy storage and insulation barrel 6, and the liquid outlet pipe 9 provides hot water for the staff; on the other hand, the density of water is greater than the density of heat transfer oil. Setting the energy storage and insulation barrel 6 in the heat energy exchange barrel 3 helps to increase the overall average density of the heat energy exchange barrel 3 and improve the installation stability of the heat energy exchange barrel 3. Preferably, the energy storage and insulation barrel 6 is located at the lower end of the heat energy exchange barrel 3.

[0031] Both ends of the heat exchange barrel 3 are provided with connection ports 16 connected to the external heating device to form a second circulation loop 15. The first heat transfer oil in the heat exchange barrel 3 circulates in the second circulation loop 15, transporting the heat in the heat exchange barrel 3 to the external heating device, providing heat for the installation site of the external heating device, so that the heat generated by the air compressor 1 compressing oxygen can be fully utilized.

[0032] Further, such as Figure 4-6 As shown, the heat recovery unit also includes an opening and closing sleeve 10 and a telescopic cylinder 11 arranged in the heat exchange barrel 3. The opening and closing sleeve 10 includes a pair of tube bodies 12. The ends of the tube bodies 12 are cantilevered with opening and closing handles 13. The axis of the tube body 12 is arranged parallel to the axis of the heat exchange barrel 3. The heat storage tube 5 is inserted between the heat exchange tubes 4 to form a heat exchange tube bundle with the heat exchange tubes 4. The tube body 12 is wrapped outside the heat exchange tube bundle and is hinged to each other to form an openable and closable cylindrical structure. The two ends of the telescopic cylinder 11 are respectively connected to the opening and closing handles 13. The tube body 12 has the freedom to swing along the hinge axis with the help of the telescopic cylinder 11. When it is necessary to store hot water at a higher temperature, the telescopic cylinder 11 is extended to open the two opening and closing handles 13, and the tube body 12 swings along the hinge axis to form a cylindrical structure, wrapping the heat exchange tube 4 and the heat storage tube 5 in the opening and closing sleeve 10, thereby hindering the heat exchange between the heat exchange tube 4 and the first heat transfer oil in the heat energy exchange barrel 3 and outside the opening and closing sleeve 10. The heat exchange tube 4 exchanges heat with the heat storage tube 5 in the opening and closing sleeve 10. The heat exchange space is small and the first heat transfer oil in the opening and closing sleeve 10 is less. Therefore, the temperature of the first heat transfer oil in the opening and closing sleeve 10 is higher, so that the heat storage tube 5 obtains a higher temperature, and the heat storage tube 5 provides hot water with a higher temperature to the energy storage insulation barrel 6.

[0033] Preferably, a pressure regulating pipe 14 is provided on the heat exchange barrel 3, and the telescopic cylinder 11 includes a cylinder body 1101 and a piston rod 1102 matched with the cylinder body 1101, and compressed gas is provided in the cylinder body 1101, and the fixed end of the cylinder body 1101 and the working end of the piston rod 1102 are respectively hinged to the two opening and closing handles 13. The piston rod 1102 includes a sealing section and an overhanging section, and the sealing section is connected to the overhanging section, wherein the sealing section is located in the cylinder body 1101 and fits the inner wall of the cylinder body 1101, and the end surface where the sealing section and the overhanging section are connected is in contact with the heat transfer oil in the heat exchange barrel 3.

[0034] The pressure regulating pipe 14 is a medium inlet and outlet pipe. The first heat transfer oil or gas is added to the heat exchange barrel 3 through the pressure regulating pipe 14, so that the pressure in the heat exchange barrel 3 increases, and the first heat transfer oil in the heat exchange barrel 3 presses the piston rod 1102 to move into the cylinder body 1101, and the length of the telescopic cylinder 11 is shortened; the first heat transfer oil or gas in the heat exchange barrel 3 is released outward through the pressure regulating pipe 14, the pressure in the heat exchange barrel 3 decreases, and the compressed gas in the cylinder body 1101 expands to push the piston rod 1102 outward, so that the length of the telescopic cylinder 11 becomes longer, thereby driving the opening and closing of the opening and closing sleeve 10 with the help of the telescopic cylinder 11.

[0035] When the required water temperature in the energy storage and insulation barrel 6 is lowered, or the two ends of the heat exchange barrel 3 are respectively connected to the external heating equipment, and the external heating equipment needs to provide heating to the outside, the telescopic cylinder 11 is shortened, and the tube body 12 is swung open along the hinge axis, thereby improving the thermal conductivity of the first heat transfer oil in the heat exchange barrel 3 and the heat exchange tube 4, so that the first heat transfer oil in the heat exchange barrel 3 obtains a higher temperature.

[0036] like Figure 1-2 As shown, the oxygen production equipment of this embodiment also includes a support 17 and a box 18. The box 18 is covered on the support 17. The oxygen production host, air compressor 1, oxygen storage tank 2 and heat recovery unit are all located in the box 18 and installed on the support 17. With the help of the support 17 and the box 18, a cabin-type oxygen production equipment is formed. When a workplace needs to prepare oxygen on site, the cabin-type oxygen production equipment of this embodiment is directly transported to the workplace, and oxygen production can be carried out without on-site debugging and installation. It is convenient to use. Only tap water is connected to the infusion pipe 8 to continuously recover the heat generated by the air compressor 1 compressing oxygen, so that the heat is fully utilized and energy waste is reduced.
