Description

Technical Field

[0001] This utility model relates to the field of fermentation equipment accessories, and in particular to a reversing heat exchanger for fermentation equipment. Background Technology

[0002] Large-scale farming generates a significant amount of manure, such as chicken, duck, or bird droppings. To reduce pollution, this manure is often processed into bio-organic fertilizer using fermentation equipment. However, the fermentation process within the equipment introduces a high concentration of suspended pollutants into the air, and the heat generated further heats the air, making it highly humid.

[0003] Therefore, the air inside the fermentation equipment needs to be purified, filtered, and otherwise treated before being discharged. In the post-treatment process, heat exchangers are often used to recover heat from the air to reduce energy waste.

[0004] Most common heat exchangers are linear, meaning the hot and cold air streams generated by the fermentation equipment pass through the heat exchanger in parallel. However, in practical use, it has been found that there is sometimes a significant height difference between the exhaust height of the fermentation equipment and the intake height of the air that needs to be heated through heat exchange. Linear heat exchangers have a smaller height difference with the ports connecting to these two devices, requiring a large number of pipes for matching, which is difficult to install and occupies a lot of space. Utility Model Content

[0005] The purpose of this invention is to provide a reversing heat exchanger for fermentation equipment, which can solve one or more of the above-mentioned problems.

[0006] According to one aspect of this utility model, a reversing heat exchanger for a fermentation device is provided, comprising a heat exchange block, a shell, and a support. The housing is mounted on a bracket. A first air inlet is located on one side of the housing, and a first air outlet is located on the other side. A second air inlet is located at the bottom of the housing, and a second air outlet is located at the top. The housing includes a box body with openings on both sides, bottom, and top. The heat exchange block is embedded in the box body and covers all the openings on the box body. The heat exchange block has multiple longitudinal and transverse holes, and the longitudinal and transverse holes are not connected. The first air inlet and the first air outlet are respectively connected to the horizontal hole, and the second air inlet and the second air outlet are respectively connected to the vertical hole.

[0007] The beneficial effects of this invention are as follows: This invention can be used for the treatment of high-temperature exhaust gas from fermentation equipment. The high-temperature exhaust gas discharged from the fermentation equipment can enter through the first inlet, pass through the horizontal holes of the heat exchange block, and then exit through the first outlet to be input into subsequent treatment equipment. Meanwhile, external air can enter through the second inlet, pass through the vertical holes of the heat exchange block, and then exit through the second outlet to be input into subsequent gas-demanding equipment. When the high-temperature exhaust gas and external air pass through the heat exchange block simultaneously, the heat in the high-temperature exhaust gas can be transferred to the external air through the heat exchange block, achieving heat exchange and effectively recovering the heat energy from the exhaust gas.

[0008] In this invention, by covering all openings in the housing with heat exchange blocks and providing independent longitudinal and transverse holes, it is ensured that high-temperature exhaust gas and external air inevitably pass through the heat exchange blocks when flowing through the invention, guaranteeing effective heat exchange. Furthermore, the high-temperature exhaust gas and external air do not come into contact, preventing external air contamination. Simultaneously, because the longitudinal and transverse holes have different directions, the airflow directions involved in heat exchange can differ, better adapting to the connection and use of fermentation equipment with significant height differences and equipment requiring high-heat gases, reducing the difficulty of pipeline layout and improving the reliability of airflow delivery.

[0009] In some embodiments, the housing includes a first connecting block, a second connecting block, a third connecting block, and a fourth connecting block. The first connecting block is connected to one side of the housing, and the first air inlet is located on the first connecting block. The second connecting block is connected to the other side of the housing, and the first air outlet is located on the second connecting block. The third connecting block is connected to the bottom of the housing, and the second air inlet is located on the third connecting block. The fourth connecting block is connected to the top of the housing, and the second air outlet is located on the fourth connecting block. The connecting blocks facilitate the connection between the housing and external devices.

[0010] In some embodiments, the housing has openings on both sides, bottom and top, and the heat exchange block is disposed inside the housing, covering each opening on the housing.

[0011] In some embodiments, the present invention further includes a filter screen, wherein the side of the first connecting block has a protrusion, and the filter screen is embedded in the first connecting block, and the filter screen is disposed between the first air inlet and the heat exchange block. The filter screen can filter large particles carried in the high-temperature exhaust gas transmitted from the fermentation equipment, thereby reducing the probability of the high-temperature exhaust gas causing blockage of the longitudinal holes when passing through them.

[0012] In some embodiments, the present invention further includes a first air pipe, which is provided with a first flange. The first flange is connected to a second connecting block, and the first air pipe is connected to a first air outlet. The first flange can improve the connection reliability of the first air pipe and the second connecting block.

[0013] In some embodiments, the present invention further includes a second air pipe and an exhaust fan, wherein the exhaust fan is connected to a third connecting block via the second air pipe, and the exhaust fan is connected to a second air inlet via the second air pipe. The exhaust fan can easily provide sufficient power to ensure that the outside air entering from the second air inlet can effectively pass through the second air outlet.

[0014] In some embodiments, the present invention further includes a third air pipe, which is provided with a second flange. The second flange is connected to a fourth connecting block, and the third air pipe is connected to a second air outlet. The second flange can improve the connection reliability between the third air pipe and the fourth connecting block.

[0015] In some embodiments, the second, third, and fourth connecting blocks are each provided with an inclined surface. The inclined surface can make the airflow passing through the connecting blocks more concentrated. Attached Figure Description

[0031] In addition, the second connecting block 23, the third connecting block 24 and the fourth connecting block 25 are respectively provided with inclined surfaces 20, which cause the cross-sectional area of ​​the second connecting block 23, the third connecting block 24 and the fourth connecting block 25 to gradually decrease in the direction away from the box body 21.

[0032] The reversing heat exchanger of this fermentation equipment also includes a first gas pipe 4, on which a first flange 41 is provided, and a flange is also provided on the second connecting block 23.

Furthermore, the high-temperature exhaust gas and external air do not come into contact, preventing external air contamination. Simultaneously, because the longitudinal holes 11 and transverse holes 12 have different directions, the airflow directions involved in heat exchange can be different, better adapting to the connection and use of fermentation equipment with significant height differences and equipment requiring high-heat gases, thus improving the reliability of airflow delivery.
