BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic structural diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0011] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to describe in detail the specific embodiments, structures, features and their effects according to the present utility model.

[0012] Embodiment 1:

[0013] As Figure 1As shown in the figure, the utility model discloses an organic waste gas condensation and reuse device, which includes an exhaust gas input pipeline 1 and an exhaust gas output pipeline 2. An intake air box body 3 is arranged at the end of the exhaust gas input pipeline 1, and a cooling box body 4 is arranged between the intake air box body 3 and the exhaust gas output pipeline 2. The cooling box body 4 is arranged vertically upward, and an air outlet pipe 12 is arranged at the top of the cooling box body 4. The air outlet pipe 12 is connected to the exhaust gas output pipeline 2. An air inlet pipe 5 is arranged at the bottom of the cooling box body 4. The air inlet pipe 5 extends downward and penetrates through the intake air box body 3. An air inlet 6 is arranged on the side wall of the air inlet pipe 5 inside the intake air box body 3, and a liquid discharge port 9 is arranged at the end of the air inlet pipe 5 outside the intake air box body 3. An organic matter storage tank 11 is hermetically arranged at the end of the air inlet pipe 5 outside the intake air box body 3. The organic matter storage tank 11 is hermetically connected to the air inlet pipe 5. A jacket 13 is arranged inside the cooling box body 4. A gap is formed between the jacket 13 and the cooling box body 4. Two partition plates 14 are arranged at intervals in the gap between the jacket 13 and the cooling box body 4. The partition plates 14 divide the gap between the jacket 13 and the cooling box body 4 into two independent cavities. Cooling pipes 7 are arranged inside the cooling box body 4. Both ends of the cooling pipes 7 are communicated with the two cavities respectively. A liquid inlet pipe 15 and a liquid outlet pipe 16 are arranged on the side walls of the cooling box body 4 corresponding to the two cavities respectively. The liquid inlet pipe 15 and the liquid outlet pipe 16 are connected to a cold source.

[0014] During the coating preparation process, organic waste gas at a relatively high temperature is generated, and the organic matter volatilized from the organic solvent enters the waste gas. When the organic waste gas enters the intake air box body 3 from the exhaust gas input pipeline 1 and then enters the cooling box body 4 from the air inlet pipe 5, the cold source delivers cold energy to the cavity between the jacket 13 and the cooling box body 4 and the cooling pipes 7, so as to cool the organic waste gas in the cooling box body 4. At the same time, the inner wall temperature of the jacket 13 is relatively low. During this process, organic matter will condense and adhere to the inner wall of the jacket 13, reducing the organic matter content in the organic waste gas. The organic waste gas is transported to the waste gas treatment system through the exhaust gas output pipeline 2 for waste gas treatment. Since the organic matter is reduced, the waste gas treatment efficiency is better and the treatment cost is lower. The condensed organic matter flows along the inner wall of the jacket 13 to the air inlet pipe 5 and finally discharges from the liquid discharge port 9 at the bottom of the air inlet pipe 5 into the organic matter storage tank 11. The partition plate 14 is used to divide the gap between the jacket 13 and the cooling box body 4 into two cavities. The liquid inlet pipe 15 is connected to one cavity, and the liquid outlet pipe 16 is connected to the other cavity, so as to ensure that the cooling medium enters one cavity from the liquid inlet pipe 15, flows through the cooling pipes 7 to the other cavity, and then returns to the cold source from the liquid outlet pipe 16 to realize the circulation of the cooling medium. When the organic matter storage tank 11 is collected to a certain extent, it can be replaced, so as to reuse the organic matter. Since the caliber of the liquid discharge port 9 at the bottom of the air inlet pipe 5 is small, the organic matter in the organic matter storage tank 11 is not easy to volatilize, avoiding the re-volatilization of the collected organic matter and affecting the condensation and removal efficiency of the organic matter in the waste gas.

[0015] The air inlet 6 on the air inlet pipe 5 in the air inlet box 3 faces the connection between the waste gas input pipe 1 and the air inlet box 3, and the diameter of the opening is larger than that of the waste gas input pipe 1. Since the air inlet 6 on the air inlet pipe 5 faces the waste gas input pipe 1, the transportation of the organic waste gas from the waste gas input pipe 1 to the air inlet pipe 5 is more stable and smooth, reducing the blockage of the organic waste gas transportation.

[0016] Both the cooling box 4 and the air inlet box 3 are of a hollow cylindrical structure. The inner diameter of the cooling box 4 is larger than that of the air inlet box 3, and the inner diameter of the air inlet box 3 is larger than the outer diameter of the air inlet pipe 5. With this structure, the speed of the waste gas transportation slows down relatively after the organic waste gas enters the air inlet pipe 5 from the waste gas input pipe 1, and after entering the cooling box 4, the waste gas flow rate slows down again. As a result, the residence time of the waste gas in the cooling box 4 is longer, the cooling effect is better, and the organic matter in the organic waste gas can be condensed more fully, thereby improving the recovery effect of the organic matter.

[0017] A connecting sleeve 10 is provided on the lower surface of the bottom of the air inlet box 3. The connecting sleeve 10 covers the outside of the air inlet pipe 5, and the connecting sleeve 10 is hermetically connected to the air inlet box 3. An external thread is provided on the outer wall of the lower end of the connecting sleeve 10, and an internal thread is provided at the top opening of the organic matter storage tank 11. The internal thread of the organic matter storage tank 11 is in sealing fit with the external thread of the connecting sleeve 10. The connecting sleeve 10 is used for the installation and connection of the organic matter storage tank 11, and the operation is simple and convenient. A sealing ring can be provided between the connecting sleeve 10 and the organic matter storage tank 11 for sealing connection. As for the specific sealing structure, it is known prior art and will not be elaborated here. Since the connecting sleeve 10 is sleeved on the outside of the air inlet pipe 5, when the organic matter storage tank 11 is connected to the connecting sleeve 10, the liquid discharge port 9 of the air inlet pipe 5 is naturally inside the organic matter storage tank 11, enabling the condensed organic matter to flow into the organic matter storage tank 11 for easy collection.

[0018] A cooling medium is provided in the cooling pipe 7 and the cavity. The liquid inlet pipe 15 and the liquid outlet pipe 16 are connected to the compressor 8, and the compressor 8 is used to cool the cooling medium. Of course, there are many forms of cooling. In this embodiment, the compressor 8 is used to cool the medium in the cooling pipe 7. Similar to the principle of an air conditioner, the cooling effect is good and the controllability is high.
