[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" 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.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0026] Example 1

[0027] like Figure 1-4 As shown, a device for condensing and recovering alcohol-containing gas discharged from fluidized boiling granulation of traditional Chinese medicine wine paste includes an exhaust pipe 2. The exhaust pipe 2 is a galvanized pipe that can exchange heat with the outside environment and has high structural strength and high corrosion resistance. A rain cover 3 is connected to the upper end of the exhaust pipe 2 to prevent rain and dirt from falling into the exhaust pipe 2. The lower end of the exhaust pipe 2 is connected to a tail gas pipe 4. The tail gas containing alcohol is discharged through the tail gas pipe 4 and then enters the exhaust pipe 2, and is then discharged to the outside.

[0028] The vent pipe 2 is connected to a condensation recovery structure, which includes a heat exchange structure 1 installed on the vent pipe 2. The heat exchange structure 1 allows a condensation surface to be formed inside the vent pipe 2, which is in contact with the exhaust airflow. In this embodiment, the condensation recovery structure includes a condensation coil 104 installed outside the vent pipe 2. The condensation coil 104 is connected to the refrigerant, and the inner wall of the vent pipe 2 forms a condensation surface. The condensation coil 104 is thermally connected to the condensation surface. Specifically, the condensation coil 104 is fitted onto a connecting pipe 102, which is made of galvanized pipe. The condensation coil 104 is also formed by bending galvanized pipe. Connecting flanges 101 are pre-installed at both the upper and lower ends of the connecting pipe 102. The connecting pipe 102, condensation coil 104, and connecting flanges 101 are then pre-installed and finally installed onto the vent pipe 2. For ease of installation and maintenance, the connecting pipe 102 is installed at the lower end of the drain pipe 2, thereby providing forced cooling in the initial stage and improving the condensation effect of the alcohol. The lower end of the condensing coil 104 is connected to the refrigerant inlet pipe 105, and the upper end of the condensing coil 104 is connected to the refrigerant outlet pipe 106, which can reduce the flow rate in the condensing coil 104 and improve the heat exchange effect, thereby connecting to the refrigerant. In this embodiment, the refrigerant can be tap water or well water, and the flow can be controlled by a pump, which is low-cost. A protective cover 103 is installed outside the condensing coil 104, and a heat insulation layer can be installed on the inner wall of the protective cover 103, thereby enabling the condensing coil 104 and the connecting pipe 102 to fully exchange heat. The inner wall of the connecting pipe 102 and the inner wall of the drain pipe 2 near the connecting pipe 102 form a condensation surface, causing the alcohol to condense and fall along the inner wall.

[0029] The drain pipe 2 is also connected to an alcohol collection structure 5. Alcohol condensed on the condensing surface flows into the alcohol collection structure 5. In this embodiment, the alcohol collection structure 5 is connected to the lower end of the connecting pipe 102. The alcohol collection structure 5 includes a collection tank 501, and an alcohol enrichment structure 503 is installed on the upper end of the collection tank 501. Alcohol collected by the alcohol enrichment structure 503 flows into the collection tank 501. Specifically, the alcohol enrichment structure 503 includes an arc-shaped collection cover 504. The collection cover 504 is a stainless steel cover, formed by stamping, with an upward arc in the middle and connecting rings 507 formed at the edges. A connecting hole 506 is machined on the connecting ring 507 to form a sealed connection with the flange. The edge of the collecting cover 504 is the lowest point, which allows alcohol to accumulate at the edge of the collecting cover 504. Downward through holes 505 are uniformly machined on the edge of the collecting cover 504. The diameter of the through holes 505 is 2-3mm. The accumulated alcohol falls through the through holes 505. At the same time, the through holes 505 are blocked to form a one-way conduction, reducing the upward overflow of alcohol vapor in the collecting tank 501. The lower end of the collecting tank 501 is connected to a recovery pipe 502 with a valve to facilitate the centralized recovery of the collected alcohol.

[0030] Example 2

[0031] like Figure 5As shown, a device for condensing and recovering alcohol-containing gas discharged from fluidized boiling granulation of traditional Chinese medicine wine paste differs from Embodiment 1 in that the condensation recovery structure includes a condensation chamber 107 installed outside the connecting pipe 102. The condensation chamber 107 is connected to a refrigerant. The lower end of the condensation chamber 107 is connected to a refrigerant inlet pipe 105, and the upper end of the condensation chamber 107 is connected to a refrigerant outlet pipe 106. The outer wall of the refrigerant chamber is made of galvanized sheet and is sealed. A heat insulation layer is wrapped around the galvanized sheet.

[0032] Compared with Example 1, the advantages of this example are that the structure is simpler and the cost is lower. The disadvantage is that the outer wall of the refrigerant cavity lacks support and is prone to deformation and damage.

[0033] Example 3

[0034] like Figure 6-7 As shown, a device for condensing and recovering alcohol-containing gas discharged from fluidized boiling granulation of traditional Chinese medicine wine paste differs from embodiments 1-2 in that the condensation recovery structure includes a heat-conducting pipe 108 inserted inside a connecting pipe 102, with the end of the heat-conducting pipe 108 extending outside the connecting pipe 102 and the heat-conducting pipe 108 angled upwards. An air guide shroud 109 that cooperates with the heat-conducting pipe 108 is installed on the outer wall of the connecting pipe 102. In this embodiment, the air guide shroud 109 faces south, corresponding to the summer wind direction. The airflow collected by the air guide shroud 107 passes through the heat-conducting pipe 108, increasing the flow velocity and quickly carrying away heat. A spray pipe can be installed on the air guide shroud 109 to improve the cooling effect.

[0035] Compared with Examples 1-2, the advantage of this example is that it does not require a refrigerant system and has a simpler structure. The disadvantage is that for cases with large exhaust emissions, the alcohol recovery effect is poor and it still needs to be connected to a refrigerant. The refrigerant passes through the heat pipe 108 and then quickly removes heat.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
