Description

Technical Field

[0001] This utility model relates to the field of rotary desorption equipment, specifically a rotary desorption heat utilization and circulation device. Background Technology

[0002] Rotary adsorption concentration technology mainly consists of a pretreatment device, an adsorption rotor, a desorption system, and a control system. Its working principle is as follows: Waste gas containing volatile organic compounds (VOCs) passes through the pretreatment device to remove particulate matter, dust, and other impurities before entering the adsorption zone of the adsorption rotor. The adsorption rotor is typically made of hydrophobic zeolite or other adsorption materials, which have high specific surface area and good adsorption performance. The VOCs in the waste gas are adsorbed onto the adsorption material of the rotor, while the purified air is discharged from the system. As the rotor slowly rotates, the saturated adsorption area continuously moves, while new adsorption areas continuously contact the waste gas for adsorption. When some areas of the adsorption rotor become saturated, the gas enters the desorption zone. In the desorption zone, high-temperature gas (such as hot air or steam) is typically used to heat the adsorption material. The high temperature causes the VOCs adsorbed on the rotor to desorb, forming a high-concentration desorbed gas. The desorbed gas is then transported to subsequent treatment devices, such as catalytic combustion equipment or regenerative thermal oxidizers, for further treatment, converting the VOCs into harmless substances.

[0003] The desorption process of the rotor requires a lot of energy to provide high-temperature desorption gas, usually through electric heating, gas heating or steam heating. If the heat generated by desorption cannot be recovered and utilized, this energy will be wasted, increasing the company's energy costs. Utility Model Content

[0020] Please see Figure 1-5 This utility model provides a rotating wheel desorption heat utilization circulation device, including a heat utilization cylinder 1. A rear end cover 6 is fixedly installed at one end of the heat utilization cylinder 1, and a front end cover 8 is fixedly installed at the other end of the heat utilization cylinder 1. At the same time, a gas distribution pipe 9 is fixedly installed on the front end cover 8, and a gas outlet pipe 7 is fixedly installed on the rear end cover 6. A first heat exchange tube 3, a second heat exchange tube 31, and a third heat exchange tube 32 are respectively installed inside the heat utilization cylinder 1. A hot gas inlet plate 4 is provided at the inlet end of the first heat exchange tube 3, the second heat exchange tube 31, and the third heat exchange tube 32, and a hot gas outlet plate 5 is provided at the outlet end of the first heat exchange tube 3, the second heat exchange tube 31, and the third heat exchange tube 32.

[0021] Working Principle: During operation, the desorbed high-temperature gas enters the hot gas inlet plate 4 through the hot gas inlet pipe 41. The hot gas inlet plate 4 directs the gas into the first heat exchange tube 3, the second heat exchange tube 31, and the third heat exchange tube 32. All three heat exchange tubes are spiral structures made of copper. Finally, the gas enters the hot gas outlet plate 5 and exits through the hot gas outlet pipe 51. Simultaneously, the low-temperature gas about to be adsorbed into the rotor enters the inlet pipe 11 and fills the inlet plate 10. Under the diversion of the three-component gas pipes 9, the gas is divided into three groups and sequentially enters the heat utilization cylinder 1. Since the three-component gas pipes 9 are respectively positioned opposite the first heat exchange tube 3, the second heat exchange tube 31, and the third heat exchange tube 32, the three groups of gas need to be diverted... The gas to be heated flows through the first heat exchange tube 3, the second heat exchange tube 31, and the third heat exchange tube 32 respectively. The gas to be heated and the high-temperature gas flow in opposite directions, forming a countercurrent, thus completing the efficient heating of the gas to be heated. At the same time, the first heat exchange tube 3, the second heat exchange tube 31, and the third heat exchange tube 32 are arranged in a spiral shape, increasing the contact area between the gas and the heat exchange tubes and improving the heating effect of the gas. The first heat exchange tube 3, the second heat exchange tube 31, and the third heat exchange tube 32 are limited and fixed inside the heat utilization cylinder 1 by three sets of limiting plates 2. The setting of the three sets of limiting plates 2 facilitates the limiting support of the three sets of heat exchange tubes, and at the same time, it can slow down the gas flowing inside the heat utilization cylinder 1, reduce the flow velocity of the gas inside the heat utilization cylinder 1, increase the heat exchange time between the gas inside the heat utilization cylinder 1 and the heat exchange tubes, and further improve the heating efficiency of the gas.

[0022] This device is installed at the desorbed gas outlet and the inlet preheating section. The desorbed high-temperature gas is introduced into the interior of the first heat exchange tube 3, the second heat exchange tube 31 and the third heat exchange tube 32 through the hot gas inlet pipe 41. This preheats the low-temperature gas inside the heat utilization cylinder 1 that is about to enter the rotor for adsorption, thereby increasing the inlet temperature and reducing the energy required for subsequent heating and desorption. This can significantly reduce heating energy consumption and improve energy utilization efficiency.

[0023] In a preferred embodiment, the first heat exchange tube 3, the second heat exchange tube 31, and the third heat exchange tube 32 are all spiral structures made of copper. The first heat exchange tube 3, the second heat exchange tube 31, and the third heat exchange tube 32 are fixed inside the heat utilization cylinder 1 by three sets of limiting plates 2.

[0024] The distance between two adjacent sets of limiting plates 2 is consistent, and the limiting plates 2 are circular. At the same time, the axial cross-section of the limiting plates 2 and the heat utilization cylinder 1 are concentric circles, and three sets of vent holes are evenly opened on the surface of the limiting plates 2.

[0025] In a preferred embodiment, both the hot air inlet plate 4 and the hot air outlet plate 5 are circular, and a hot air inlet pipe 41 is installed at the end of the hot air inlet plate 4, while a hot air outlet pipe 51 is installed at the end of the hot air outlet plate 5. Both the hot air outlet pipe 51 and the hot air inlet pipe 41 are embedded and fixed on the side wall of the heat utilization cylinder 1.

[0026] Three sets of equidistant gas distribution pipes 9 are evenly arranged on the front cover 8, and the three sets of gas distribution pipes 9 are respectively arranged opposite to the first heat exchange pipe 3, the second heat exchange pipe 31 and the third heat exchange pipe 32.

[0027] In a preferred embodiment, the three-part air intake pipe 9 is installed at the bottom of the circular air intake plate 10, and an air intake pipe 11 is fixedly installed on the air intake plate 10. At the same time, the axial cross-section of the air intake plate 10, the hot air inlet plate 4 and the hot air outlet plate 5 are concentric circles.
