This phenomenon can cause various problems: part of the raw materials will flow into the pipeline system with waste gas, which cannot be recycled; raw material waste gas without effective separation is directly discharged, polluting the air; waste gas fan is frequently damaged due to inhaling waste gas containing liquid; residual raw materials in the waste gas pipeline may leak into the product tank area, affecting product quality and threatening the safety of workers. These problems have long plagued relevant enterprises. Therefore, an economical and practical and efficient solution is needed to optimize the performance of the waste gas treatment system, reduce raw material waste, reduce environmental pollution, protect equipment safety and improve overall economic efficiency.

DETAILED DESCRIPTION

[0022] The embodiment of the utility model is described in detail below, and reference is made to Figures 1 to 2The embodiment of the utility model provides a kind of gas-liquid separation device for water-based exhaust pipe, comprising: finished product tank 1, waste water tank 15, exhaust fan and emulsion tank 22, finished product tank 1 is connected with first pipeline 3, it is equipped with seventh pipeline 2 between first pipeline 3 and finished product tank 1, seventh pipeline 2 includes four 90 elbow, seventh pipeline 2 is located directly above first pipeline 3, the directly below of first pipeline 3 is equipped with sixth pipeline 4, it is equipped with eleventh valve 5 on sixth pipeline 4, eleventh valve 5 is always open 1 / 3;Waste water tank 15 is connected with first pipeline 3 by second pipeline 7 and fifth pipeline 14, fifth pipeline 14 includes two 90 elbow and tenth valve 13, tenth valve 13 is always open 1 / 3;Second pipeline 7 is connected with fourth pipeline 8 between exhaust fan, fourth pipeline 8 includes 5 90 elbow, fourth pipeline 8 is installed in the side of first pipeline 3, the height difference of the top of fourth pipeline 8 and tenth valve 13 is greater than or equal to 2 meters, fourth pipeline 8 is communicated with ninth valve 9, so that exhaust gas can be directed to exhaust fan direction;Emulsion tank 22 and first pipeline 3 are sequentially connected by eighth pipeline 23, third pipeline 24 and ninth pipeline 25, the height difference of the top of third pipeline 24 and the top of emulsion tank 22 is greater than or equal to 2 meters.When exhaust gas flows to the direction of finished product tank 1, cut off original exhaust pipeline first pipeline 3, add sixth pipeline 4 and seventh pipeline 2 for residual liquid is discharged into waste water ditch 6.Simultaneously, when exhaust gas flows to the direction of fan, cut off original exhaust second pipeline 7, add fourth pipeline 8 and fifth pipeline 14 for residual liquid is discharged into high concentration waste water tank 15;By adding corresponding pipeline, the present application can effectively separate liquid component in exhaust gas, and directly discharge it into waste water tank 15, thereby minimizing raw material loss, so that the improved exhaust pipe eliminates the phenomenon that exhaust gas is directly discharged, reduces the emission amount of pollutants.Moreover, multi-stage elbow and manual valve effectively prevent exhaust fan from sucking exhaust gas containing liquid, significantly reduce the failure rate and maintenance rate of fan.

[0023] Further, with reference to Figure 1The unimproved gas-liquid separation device mentioned in the utility model is shown in the figure, waste gas enters the first pipeline 3 from the finished product tank 1, the first pipeline 3 is connected with the waste gas fan through the second pipeline 7, meanwhile the emulsification tank 22 is connected with the first pipeline 3 through the third pipeline 24, after the waste gas passes through the branch point in the first pipeline 3, part of the waste gas enters the second pipeline 7, the ninth valve 9 is arranged on the second pipeline 7 for adjusting the flow direction of the waste gas, the waste gas enters the water washing tower 29 through the third pipeline 24, here the waste gas contacts with the washing liquid, and part of the pollutants in the waste gas are removed, the inlet and outlet of the water washing tower 29 are provided with the first valve 27 and the second valve 30 for controlling the water flow and the waste gas flow, the bottom of the water washing tower 29 is provided with the circulating pump 26 for circulating the washing liquid back to the water washing tower 29. The treated waste gas enters the waste gas furnace 28 through the pipeline, here the waste gas is treated at high temperature. The technical problem brought by this process is that a large amount of bubbles will be generated when the emulsification tank 22 is stirred, therefore the liquid level in the tank will rise, and the raw materials in the emulsification tank 22 will directly leak into the finished product tank 1 area through the third pipeline 24 into the first pipeline 3, meanwhile the raw materials will also directly enter the waste gas fan through the second pipeline 7, causing the damage of the waste gas fan, waste of raw materials and direct discharge of raw material waste gas, polluting the environment and existing certain safety hazards. Further, Figure 2 On the basis of Figure 1 The first pipeline 3 is cut off, the sixth pipeline 4 and the seventh pipeline 2 are added, the finished product tank 1 is connected with the first pipeline 3, the seventh pipeline 2 is arranged between the first pipeline 3 and the finished product tank 1, the seventh pipeline 2 comprises four 90° elbows, the seventh pipeline 2 is located directly above the first pipeline 3, this structure can utilize the action of gravity to make the liquid components in the waste gas naturally sink, and can also prevent the backflow of the gas. Using multiple elbows can effectively improve the direction of the fluid, and the combination of multiple elbows can significantly reduce the pressure loss inside the whole pipeline. Further, the sixth pipeline 4 is arranged directly below the first pipeline 3, the eleventh valve 5 is arranged on the sixth pipeline 4, the eleventh valve 5 is always opened by 1 / 3, the sixth pipeline 4 is communicated with the waste water ditch 6 in the factory building through the eleventh valve 5, so as to prevent the waste gas raw materials in the first pipeline 3 from entering the finished product tank 1. The residual raw materials in the first pipeline 3 are directly discharged to the waste water ditch 6 in the factory building through the sixth pipeline 4 due to gravity, so as to prevent the corresponding waste gas raw materials from entering the finished product tank 1 area and affecting the environment.

[0024] Further, on the basis of Figure 1Based on this, the second pipe 7 will be cut off, and a fourth pipe 8 and a fifth pipe 14 will be added. The second pipe 7 will be connected to the exhaust fan via the fourth pipe 8, which includes five 90° bends. The fourth pipe 8 will be installed on the side of the first pipe 3, and the height difference between the top of the fourth pipe 8 and the tenth valve 13 will be greater than or equal to 2 meters. This structural design is mainly to prevent the waste gas and liquid in the second pipe 7 from entering the exhaust fan. Under the action of gravitational potential energy, the residual raw materials in the second pipe 7 will be directly discharged into the wastewater tank 15 on the first floor of the factory building, while the waste gas will enter the exhaust fan through the fourth pipe 8 and then through the ninth valve 9. This prevents waste gas and raw materials from entering the exhaust fan and affecting the environment or damaging the fan. Furthermore, in Figure 1 Based on this, the height of the third pipe 24 connected to the emulsification tank 22 is increased. Of course, this utility model does not limit the specific height of the third pipe 24. Preferably, the height difference between the top of the third pipe 24 and the top of the emulsification tank 22 is greater than or equal to 2 meters, so as to prevent the liquid level in the emulsification tank 22 from rising during stirring and causing liquid to enter the third pipe 24. At the same time, an eighth pipe 23 and a ninth pipe 25 are added on both sides of the third pipe 24. The ninth pipe 25 is directly connected to the second pipe 7, and the eighth pipe 23 is connected to the emulsification tank 22, so as to prevent the raw materials in the emulsification tank 22 from entering the first pipe 3, further enhancing the gas-liquid separation effect.

[0025] Further, the gas-liquid separation device mentioned in the present application also includes a water washing tower 29 and a circulating pump 26. The exhaust gas enters the water washing tower 29 through the third valve 21, and an exhaust gas furnace 28 is arranged directly above the water washing tower 29. The exhaust gas is discharged into the exhaust gas furnace 28 after passing through the water washing tower 29 and the circulating pump 26. This makes the entire system not only limited to simple gas-liquid separation, but also extended to the field of exhaust gas purification. The exhaust gas first enters the water washing tower 29 through the third valve 21, where it is preliminarily cleaned to remove particulate matter and other soluble pollutants. Subsequently, the cleaned exhaust gas is finally discharged into the exhaust gas furnace 28 for incineration treatment through the action of the circulating pump 26. This process not only achieves the maximum removal of harmful substances in the exhaust gas, but also provides the possibility for subsequent energy recovery. Through such a closed-loop design, enterprises can not only meet environmental regulations, but also maximize the use of resources. Further, the circulating pump 26 is connected with the water washing tower 29 through the first valve 27 and the second valve 30. The circulating pump 26 realizes precise control through the first large valve 27 and the second valve 30. This design allows the direction and flow of water to be adjusted according to actual needs, ensuring that the water washing tower 29 is always in the best working condition. Further, the exhaust gas fan includes the first fan 19 and the second fan 11. The exhaust gas flowing through the fourth pipeline 8 enters the first fan 19 and the second fan 11 through the ninth valve 9, respectively. The first fan 19 is in communication with the water washing tower 29 through the fourth valve 20 and the third valve 21 in turn. The design of double exhaust gas fans ensures that the entire production line will not be interrupted, even if one fan fails, the other can still work. Further, the second fan 11 is in communication with the first fan 19 through the fifth valve 12. This cross-connection design provides a new flow regulation mechanism: when the load on one side is too high, the pressure difference between the two sides can be balanced by opening or closing the fifth valve 12, thereby avoiding equipment damage caused by single-sided overload. In addition, this design also allows a series mode to be formed under certain conditions, further improving the maximum processing capacity of the system. Further, the seventh valve 10 is arranged between the ninth valve 9 and the second fan 11. The seventh valve 10 provides more surprising operation control options, allowing users to more accurately control the flow direction of the exhaust gas according to actual needs. Further, a fan is arranged in the emulsifying tank 22, which is used to accelerate air circulation and prevent the surface of the emulsion from oxidizing.

[0026] Further, the wastewater tank 15 is communicated with the waste liquid furnace 17 through the eighth valve 16, so that the residual raw materials flowing into the second pipeline 7 are directly discharged into the wastewater tank 15 through the fifth pipeline 14 and then collected in the waste liquid furnace 17. That is, all the residual raw materials flowing into the second pipeline 7 are collected and sent to the waste liquid furnace 17 for harmless treatment, solving the leakage risk existing in the traditional method, and further, the waste can be converted into usable energy, greatly reducing the waste disposal cost. Further, the utility model does not limit the specific material of the elbow, and preferably, the 90° elbow is made of PVC material. PVC has excellent corrosion resistance and low cost, and is very suitable for conveying industrial wastewater or waste gas containing acid and alkali components. At the same time, PVC pipe material is light in weight, easy to process and install, which greatly shortens the construction period and reduces the labor cost.
