Description

Technical Field

[0001] This invention relates to the field of gas heating technology, specifically a uniform temperature heating device for rotating surface combustion coupled with gradient foam metal phase change heat transfer. Background Technology

[0002] Currently, gas-fired heating devices are widely used in industrial production fields such as chemical material reaction heating, metal heat treatment, glass and ceramic sintering, lithium battery electrode drying, and photovoltaic cell sintering due to their convenient fuel acquisition and fast heating response. However, in practical applications, existing gas-fired heating devices suffer from the following problems due to their structural limitations: First, uneven combustion and heat transfer in existing gas-fired heating devices result in uneven heat distribution in the circumferential direction, leading to uneven heating and affecting the temperature consistency and processing quality of the heated object. Second, existing gas-fired heating devices cannot utilize the waste heat of flue gas to increase the inlet air temperature, resulting in both direct exhaust of flue gas and low inlet air temperature, thus leading to low overall thermal utilization and combustion efficiency.

Detailed Implementation

[0030] A uniform heating device for rotating surface combustion coupled with gradient foam metal phase change heat transfer includes an outer sleeve 1 that is closed at the left end and open at the right end; the left end wall of the outer sleeve 1 has a central hole 1.1 through it on one side and an air inlet pipe 2 and an exhaust pipe 3 connected to it on the other side; an isolation ring 4 is fixed on the left inner end face of the outer sleeve 1. A metal fiber burner is rotatably mounted on the right end of the inner side of the outer sleeve 1; a left central shaft 5 that rotatably passes through the central hole 1.1 and an inner sleeve 6 that rotatably supports the inner side of the isolation ring 4 are respectively fixed on the metal fiber burner; an intake chamber that is simultaneously connected to the intake pipe 2 and the metal fiber burner is formed between the inner sleeve 6 and the left central shaft 5; an exhaust chamber that is simultaneously connected to the exhaust pipe 3 and the metal fiber burner is formed between the outer sleeve 1 and the inner sleeve 6. A support ring 7 is rotatably mounted on the right end of the outer side of the outer sleeve 1; a support sleeve 8, closed on the right and open on the left, is rotatably mounted on the metal fiber burner; a double-layer heat transfer tube is fixed between the support ring 7 and the support sleeve 8; a combustion chamber is formed between the inner sidewall 9 of the double-layer heat transfer tube and the metal fiber burner; a heat transfer chamber is formed between the inner sidewall 9 of the double-layer heat transfer tube and the outer sidewall 10 of the double-layer heat transfer tube; the heat transfer chamber is filled with gradient foam metal; the pores of the gradient foam metal are filled with phase change working fluid; an injection hole 10.1 is opened through the outer sidewall 10 of the double-layer heat transfer tube; a right central shaft 11 is fixed on the right outer end face of the support sleeve 8.

[0031] During operation, the outer sleeve 1 is fixedly supported on the external bracket. The support sleeve 8 is rotatably supported on the external bearing seat. An external motor is connected to the left end of the left central shaft 5 and the right end of the right central shaft 11. The filling hole 10.1 is sealed with a plug. The outer sidewall 10 of the double-layer heat transfer tube is in contact with the object being heated.

[0032] The specific working process is as follows: The premixed gas first enters the intake chamber through the intake pipe 2, then flows through the metal fiber burner to the combustion chamber, where it is ignited and thus undergoes uniform combustion. The flame and flue gas generated by combustion heat the gradient foam metal and phase change working fluid in the heat transfer chamber through the inner sidewall 9 of the double-layer heat transfer tube, causing the phase change working fluid to circulate and undergo phase change heat transfer. This heat is then transferred to the outer sidewall 10 of the double-layer heat transfer tube, thereby heating the object being heated. During this process, the flue gas is discharged outward sequentially through the combustion chamber, exhaust chamber, and exhaust pipe 3. During the discharge process, the flue gas in the exhaust chamber exchanges heat with the premixed gas in the intake chamber, thereby utilizing the waste heat of the flue gas to increase the intake temperature. This achieves both the recovery and utilization of waste heat from the flue gas and effectively increases the intake temperature, thereby effectively improving the overall heat utilization rate and combustion efficiency. Simultaneously, one external motor drives the metal fiber burner and inner sleeve 6 to rotate forward via the left central shaft 5, while the other external motor drives the support sleeve 8, double-layer heat transfer tubes, and support ring 7 to rotate in the opposite direction via the right central shaft 11. The rotation of the metal fiber burner redistributes heat circumferentially within the combustion chamber, reducing circumferential heat concentration and improving the heating uniformity of the double-layer heat transfer tubes. The rotation of the double-layer heat transfer tubes also reduces the circumferential segregation tendency of the phase change working fluid within the heat transfer chamber under gravity, promoting uniform distribution of the phase change working fluid and improving overall heat transfer uniformity.

[0033] The pore size of the gradient foam metal exhibits a radial gradient distribution; that is, the closer the pores are to the inner sidewall 9 of the double-layer heat transfer tube, the smaller their diameter; and the closer the pores are to the outer sidewall 10, the larger their diameter. During operation, based on this structure, the cyclic phase change heat transfer process of the phase change working fluid is as follows: When the inner sidewall 9 of the double-layer heat transfer tube is heated, the phase change working fluid in the radially inner region (i.e., the region near the inner sidewall 9) absorbs heat and vaporizes. The vaporized phase change working fluid diffuses outward along the pores of the gradient foam metal to the radially outer region (i.e., the region near the outer sidewall 10 of the double-layer heat transfer tube), and condenses and releases heat in the radially outer region, thereby releasing the latent heat of vaporization to the outer sidewall 10 of the double-layer heat transfer tube. Driven by the capillary force of the gradient foam metal, the condensed phase change working fluid flows inward along the pores of the gradient foam metal back to the radially inner region, thus achieving cyclic phase change heat transfer.

[0034] The phase change working medium is degassed deionized water, naphthalene, cesium, potassium, or sodium. During operation, when the target temperature of the object being heated is 150°C to 300°C, the phase change working medium is degassed deionized water. When the target temperature of the object being heated is 300°C to 380°C, the phase change working medium is naphthalene. When the target temperature of the object being heated is 400°C to 600°C, the phase change working medium is cesium. When the target temperature of the object being heated is 500°C to 700°C, the phase change working medium is potassium. When the target temperature of the object being heated is 600°C to 1100°C, the phase change working medium is sodium.

[0035] There are two intake pipes 2, which are symmetrically distributed; there are also two exhaust pipes 3, which are symmetrically distributed. During operation, the premixed fuel gas enters the intake chamber through the two intake pipes 2. The two exhaust pipes 3 ensure rapid exhaust of the flue gas.

[0038] A baffle 17 is fixed on the inner sidewall 9 of the inner layer of the double-layer heat transfer tube. During operation, the baffle 17 can increase the heat transfer area and, with the rotation of the double-layer heat transfer tube, disturb the flue gas in the combustion chamber, thereby improving the heat transfer efficiency.
