Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a dry air heat exchanger. Background Technology

[0002] Air heat exchangers use water, glycol solution, steam, heat transfer oil, or direct air contact as a medium to cool or heat forced-flowing air. Their working principle is based on the thermodynamic laws of heat transfer: high-temperature fluids (such as flue gas or hot air) flow through heat exchange elements (such as finned tubes or plates), transferring heat to low-temperature fluids (such as cold air) through conduction and convection, thus achieving temperature regulation. Air heat exchangers are indispensable in industrial applications (waste heat recovery, boiler efficiency improvement), air conditioning and refrigeration, heating and ventilation, and other fields. For example, tubular air preheaters can reduce boiler flue gas heat loss and improve efficiency; plate heat exchangers can recover heat from flue gas for power generation or heating, reducing energy consumption. Their design optimizes heat exchange area (such as finned structure), fluid path (counter-current / co-current), and materials (high thermal conductivity metals) to achieve efficient heat transfer and energy saving. In some demanding scenarios, current air heat exchangers cannot control the humidity of the air exchanged, resulting in treated gas that does not meet predetermined requirements.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, references to "embodiment," "one embodiment," "some embodiments," or "other embodiments" indicate that a specific feature, structure, or characteristic described in connection with an embodiment is included in at least some embodiments, but not necessarily all embodiments. Multiple appearances of "embodiment," "one embodiment," or "some embodiments" do not necessarily refer to the same embodiment. If the specification describes a component, feature, structure, or characteristic as "may," "may," or "can" be included, then that particular component, feature, structure, or characteristic is not required to be included. If the specification or claims refer to an element "a," it does not mean that there is only one element. If the specification or claims refer to "an additional" element, it does not exclude the existence of more than one additional element. Furthermore, specific features, structures, functions, or characteristics can be combined in one or more embodiments in any suitable manner. For example, a first embodiment can be combined with a second embodiment, provided that the specific features, structures, functions, or characteristics associated with the two embodiments are not mutually exclusive.

[0020] In the description of this utility model, unless otherwise specified, ordinal adjectives such as "first," "second," and "third" are used to describe common objects, indicating only different instances of the same object, and not implying that the objects described must be in a given order, whether temporally, spatially, sequentially, or in any other way. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 3 As shown, this utility model provides a dry air heat exchanger, comprising: Drying cylinder 1, air inlet pipe 2 located at the lower end of drying cylinder 1 and exhaust pipe 3 located at the upper end of drying cylinder 1; The interior of the drying cylinder 1 is hollow, and several detachable drying tubes 4 are installed inside the drying cylinder 1. Several filter materials 5 are placed inside the drying tubes 4, and several heating wires (not shown) are wound around the outside of the drying tubes 4. It should be noted that several heating wires are wound around the outside of the drying tube 4. When the gas needs to be heated to a predetermined temperature range, the heating wires are activated; otherwise, the heating wires are not activated, thereby realizing the heating and cooling of the air and achieving the heat exchange function.

[0023] A support frame 6 is provided at the upper and lower ends inside the drying cylinder 1. A fan blade 7 is provided inside the support frame 6. The fan blade 7 can rotate 8, and the fan blade 8 rotates in the same direction. like Figure 4 As shown, it should be noted that the fan blades 8 rotate in the same direction, which makes the gas flow from bottom to top faster. Furthermore, the fan blades agitate the gas inside the drying cylinder 1, making the gas more active within the cylinder and accelerating the absorption of moisture from the gas by the filter material, thus improving the speed of air drying. The filter material includes, but is not limited to, fibers, activated carbon, and composite materials.

[0024] A humidity sensor is fixedly installed inside the exhaust pipe 3 of the drying cylinder 1. The humidity sensor can detect the humidity data of the air inside the drying cylinder 1. When the humidity data is higher than a predetermined threshold, the exhaust pipe 3 is closed. An automatically controlled valve can be installed inside the exhaust pipe to control the opening and closing of the exhaust pipe 3. It should be noted that a humidity sensor is fixedly installed inside the exhaust pipe of the drying cylinder. The humidity sensor can detect the humidity data of the air inside the drying cylinder. When the humidity data is higher than a predetermined threshold, water is absorbed through filtration and the exhaust pipe is closed, so that the air discharged from the heat exchanger meets the predetermined requirements.

[0025] Furthermore, in the dry air heat exchanger, a pressure detector is also installed inside the drying cylinder 1 to detect the internal pressure data of the drying cylinder 1.

[0026] Furthermore, in the dry air heat exchanger, when the humidity data of the air inside the drying cylinder 1 is higher than a predetermined threshold, the air inlet pipe is closed.

[0027] It should be noted that when the exhaust pipe 3 is closed, the internal air pressure will increase. Therefore, an air pressure detector is also installed inside the drying cylinder 1 to detect the air pressure data inside the drying cylinder 1. When the humidity data of the air inside the drying cylinder 1 is higher than the predetermined threshold, the air intake pipe is closed, so as to keep the air pressure data of the drying cylinder 1 from not exceeding the predetermined value.

[0028] Furthermore, in the dry air heat exchanger, a first flange 9 is installed on the bottom of the drying cylinder 1, and the first flange 9 has several through holes 901 arranged in a circumferential array.

[0029] Furthermore, in the dry air heat exchanger, the dry air heat exchanger also includes a support platform 10, on which several screws 11 are installed. The screws 11 are connected to the first flange 9, which is equivalent to the second flange 16 having through holes. The screws 11 penetrate the through holes of the second flange to connect to the first flange 9.

[0030] Furthermore, in the dry air heat exchanger, a second flange 11 is also installed on the bottom of the drying cylinder 1, and the first flange 9 and the second flange 11 are fixedly connected by screws 12.

[0031] Furthermore, in the dry air heat exchanger, a clamping ring 13 is also installed on the drying cylinder 1 to seal the bottom of the drying cylinder.

[0032] It should be noted that the bottom of the drying cylinder is sealed by the clamping ring 13 to maintain the sealed state inside the drying cylinder 1.

[0033] Furthermore, in the dry air heat exchanger, a third flange 14 is installed on the air inlet pipe 2.

[0034] Furthermore, in the dry air heat exchanger, a fourth flange 15 is installed on the exhaust pipe 3.

[0035] External pipelines can be connected by setting the third flange 14 and the fourth flange 15.

[0036] Furthermore, in the dry air heat exchanger, the drying cylinder 3 is welded with reinforcing ribs 16.

[0037] In summary, this invention, by installing several detachable drying tubes inside the drying cylinder, arranging several filter materials inside the drying tubes, and winding several heating wires around the outside of the drying tubes, can filter out excess impurities in the air while drying. Furthermore, support frames are provided at the upper and lower ends inside the drying cylinder, and fan blades are installed within the support frames. These fan blades can rotate in the same direction, disturbing the airflow inside the drying cylinder and increasing the air drying rate. Moreover, by fixing a humidity sensor inside the exhaust pipe of the drying cylinder, the humidity data of the air inside the drying cylinder can be detected. When the humidity data exceeds a predetermined threshold, water is absorbed through filtration, and the exhaust pipe is closed, thereby ensuring that the air discharged from the heat exchanger meets predetermined requirements.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
