Description

Technical Field

[0001] This utility model belongs to the field of waste gas collection technology, and in particular relates to a distillation waste gas collection device. Background Technology

[0002] Alcohol distillation waste gas collection is a crucial part of the alcohol production process, aiming to reduce environmental pollution from waste gas and improve resource utilization efficiency. Alcohol distillation waste gas collection devices are equipment used to collect and treat waste gas generated during alcohol distillation.

[0003] However, existing technologies have some problems: existing alcohol distillation waste gas collection devices directly collect the waste gas generated during distillation into a gas storage tank for discharge, but the recyclable organic matter in the waste gas is not extracted, resulting in a waste of resources. Therefore, we propose a distillation waste gas collection device. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a distillation waste gas collection device, which can liquefy, extract and recycle organic matter in the waste gas through separation components and circulation components.

[0005] This utility model is implemented as follows: a distillation waste gas collection device includes a distillation tank, a feed pipe fixedly connected to one side of the distillation tank, an outlet pipe fixedly connected to the upper end of the distillation tank, a condenser shell connected to the outlet pipe, a separation component disposed inside the condenser shell, a circulation component disposed on the condenser shell, a liquid outlet pipe fixedly connected to the lower end of the condenser shell, a tail gas pipe fixedly connected to one side of the condenser shell, a collection component disposed on one side of the tail gas pipe, and a flow limiting component disposed on the tail gas pipe.

[0006] Optionally, the separation component includes multiple sets of heat-conducting plates and cooling pipes. The multiple sets of heat-conducting plates are all fixedly connected to the inner wall of the condensation shell. The multiple sets of heat-conducting plates are arranged alternately, and the cooling pipes are fixedly connected to the heat-conducting plates.

[0007] Optionally, the circulation assembly includes a liquid storage tank, which is fixedly connected to the outer wall of the condenser shell. A water pump is fixedly connected to the liquid storage tank, with one end of the water pump connected to the liquid storage tank and the other end of the water pump connected to a cooling pipe.

[0008] Optionally, a spiral tube is connected to the cooling pipe, the spiral tube is wound around the feed pipe, the spiral tube is connected to a condenser, and the condenser is connected to a liquid storage tank.

[0009] Optionally, the collection assembly includes a gas storage tank, the exhaust pipe is connected to the gas storage tank, a compressor is installed on the exhaust pipe, and an exhaust pipe is fixedly connected to the gas storage tank.

[0010] Optionally, the flow limiting component includes a fixed base and a flow limiting ring, both of which are fixedly connected inside the exhaust pipe. A spring is fixedly connected to the fixed base, and a flow limiting plug is fixedly connected to the spring. The flow limiting plug is adapted to the flow limiting ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model is equipped with a separation component. After the exhaust gas enters the condensation shell through the exhaust pipe, multiple sets of heat-conducting plates isolate the exhaust gas, allowing it to pass only through the gaps between the heat-conducting plates. This slows down the flow rate of the exhaust gas while increasing the flow path within the condensation shell, allowing the exhaust gas to remain in the condensation shell for a longer period of time. This enables the heat-conducting plates to absorb the heat from the exhaust gas, resulting in thorough condensation of the exhaust gas, ensuring the liquefaction of the organic matter within, and improving resource utilization.

[0013] 2. In this invention, after the coolant absorbs heat, it flows from the cooling pipe into the spiral tube. Since the spiral tube is in close contact with the surface of the feed pipe, the heat of the coolant in the spiral tube is transferred to the feed pipe, preheating the fermentation liquid to be entered into the distillation tank. This causes the solids in the fermentation liquid to settle quickly, which is beneficial for solid-liquid separation, reduces the emission of waste liquid and exhaust gas, and reduces the impact on the environment. At the same time, by absorbing the heat of the coolant through the fermentation liquid, the condenser can quickly cool the coolant, reducing the energy consumption of the condenser.

[0014] 3. This utility model is equipped with a flow-limiting component. The compressor creates a pressure difference for the exhaust gas, which pushes the flow-limiting plug and stretching spring to move. This prevents the flow-limiting plug from blocking the flow-limiting ring, allowing the exhaust gas to pass through the flow-limiting ring and enter the gas storage tank for compression and storage. After the distillation is completed, the compressor stops working, and the pressure of the compressed exhaust gas in the gas storage tank is greater than the external pressure. At the same time, the spring will automatically contract, causing the flow-limiting plug to block the flow-limiting ring and preventing the exhaust gas from flowing back. This allows the operator to directly release the organic matter from the liquid outlet pipe at the bottom of the condenser shell without worrying about exhaust gas leakage.

[0015] Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. Attached Figure Description

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] like Figures 1 to 5 As shown in the figure, the present invention provides a distillation waste gas collection device, including a distillation tank 1. The distillation tank 1 is made of stainless steel and its main function is to distill and purify the fermentation broth.

[0024] Furthermore, a feed pipe 2 is fixedly connected to one side of the distillation tank 1. The feed pipe 2 is used to add fermentation liquid to the distillation tank 1. An exhaust pipe 3 is fixedly connected to the upper end of the distillation tank 1. The exhaust pipe 3 is used to discharge the gas produced by distillation. The waste gas flows into the condenser shell 4 through the exhaust pipe 3.

[0025] Furthermore, a condenser shell 4 is connected to the exhaust pipe 3. The condenser shell 4 is made of stainless steel. The main function of the condenser shell 4 is to condense the exhaust gas, thereby liquefying and storing some of the organic matter in the exhaust gas for reuse, reducing the waste of resources.

[0026] Furthermore, a separation component 5 is provided inside the condensation shell 4. The separation component 5 includes multiple sets of heat-conducting plates 501 and cooling pipes 502. The multiple sets of heat-conducting plates 501 are all fixedly connected to the inner wall of the condensation shell 4 and are arranged in an alternating manner. The cooling pipes 502 are fixedly connected to the heat-conducting plates 501.

[0027] Specifically, the exhaust gas enters the condenser shell 4 through the exhaust pipe 3. Multiple sets of heat-conducting plates 501 isolate the exhaust gas, allowing it to pass only through the gaps between the heat-conducting plates 501. This slows down the flow rate of the exhaust gas while increasing the flow path within the condenser shell 4, allowing the exhaust gas to remain in the condenser shell 4 for a longer period of time. As a result, the heat-conducting plates 501 absorb the heat from the exhaust gas, enabling it to be fully condensed and ensuring the liquefaction of organic matter within, thereby improving resource utilization.

[0028] Furthermore, a circulation component 6 is provided on the condenser shell 4. The circulation component 6 includes a liquid storage tank 601, which is fixedly connected to the outer wall of the condenser shell 4. A water pump 602 is fixedly connected to the liquid storage tank 601. One end of the water pump 602 is connected to the liquid storage tank 601, and the other end of the water pump 602 is connected to the cooling pipe 502.

[0029] Furthermore, a spiral tube 603 is connected to the cooling pipe 502, the spiral tube 603 is wound around the feed pipe 2, the spiral tube 603 is connected to the condenser 604, and the condenser 604 is connected to the liquid storage tank 601.

[0030] Specifically, the water pump 602 draws coolant from the storage tank 601 and discharges it into the cooling pipe 502, so that the coolant cools the exhaust gas in the condenser shell 4. At the same time, the cooling pipe 502 is fixedly connected to the heat conduction plate 501, so that the heat in the heat conduction plate 501 can be dissipated quickly and the heat conduction efficiency can be improved.

[0031] Furthermore, after absorbing heat, the coolant flows from the cooling pipe 502 into the spiral tube 603. Since the spiral tube 603 is in close contact with the surface of the feed pipe 2, the heat of the coolant in the spiral tube 603 is transferred to the feed pipe 2, preheating the fermentation liquid to be entered into the distillation tank 1. This causes the solids in the fermentation liquid entering the distillation tank 1 to settle quickly, which is beneficial for solid-liquid separation, reduces the emission of waste liquid and exhaust gas, and reduces the impact on the environment. At the same time, by absorbing heat from the coolant through the fermentation liquid, the condenser 604 can quickly cool the coolant, reducing the energy consumption of the condenser 604.

[0032] Furthermore, a liquid outlet pipe 10 is fixedly connected to the lower end of the condenser shell 4, a tail gas pipe 7 is fixedly connected to one side of the condenser shell 4, a collection component 8 is provided on one side of the tail gas pipe 7, the collection component 8 includes a gas storage tank 801, the tail gas pipe 7 is connected to the gas storage tank 801, a compressor 802 is provided on the tail gas pipe 7, and an exhaust pipe 803 is fixedly connected to the gas storage tank 801.

[0033] Specifically, after the organic matter in the exhaust gas is liquefied and extracted, the remaining exhaust gas is drawn into the gas storage tank 801 by the compressor 802 for storage.

[0034] Furthermore, a flow limiting component 9 is provided inside the exhaust pipe 7. The flow limiting component 9 includes a fixed base 901 and a flow limiting ring 902. Both the fixed base 901 and the flow limiting ring 902 are fixedly connected inside the exhaust pipe 7. A spring 903 is fixedly connected to the fixed base 901. A flow limiting plug 904 is fixedly connected to the spring 903. The flow limiting plug 904 is adapted to the flow limiting ring 902.

[0035] Specifically, the compressor 802 creates a pressure difference for the exhaust gas, causing the exhaust gas to push the flow restrictor 904 and the tension spring 903 to move. This prevents the flow restrictor 904 from blocking the flow restrictor ring 902, allowing the exhaust gas to pass through the flow restrictor ring 902 and enter the gas storage tank 801 for compression and storage. When the distillation process is complete, the compressor 802 stops working, and the pressure of the compressed exhaust gas in the gas storage tank 801 is greater than the external pressure. At the same time, the spring 903 will automatically contract, causing the flow restrictor 904 to block the flow restrictor ring 902, preventing the exhaust gas from flowing back. This allows the operator to directly release the organic matter from the liquid outlet pipe 10 at the lower end of the condenser shell 4 without worrying about exhaust gas leakage.

[0036] The working principle of this utility model is as follows:

[0037] This utility model is equipped with a separation component 5. After the exhaust gas enters the condensation shell 4 through the exhaust pipe 3, multiple sets of heat-conducting plates 501 isolate the exhaust gas, so that the exhaust gas can only pass through the gaps between the heat-conducting plates 501. This slows down the flow rate of the exhaust gas and increases the flow path of the exhaust gas in the condensation shell 4, allowing the exhaust gas to stay in the condensation shell 4 for a longer time. This allows the heat-conducting plates 501 to absorb the heat in the exhaust gas, enabling the exhaust gas to be fully condensed, ensuring the liquefaction of the organic matter inside, and improving the utilization rate of resources.

[0038] After absorbing heat, the coolant in this invention flows from the cooling pipe 502 into the spiral tube 603. Since the spiral tube 603 is in close contact with the surface of the feed pipe 2, the heat of the coolant in the spiral tube 603 is transferred to the feed pipe 2, preheating the fermentation liquid to be entered into the distillation tank 1. This causes the solids in the fermentation liquid to settle quickly, which is beneficial for solid-liquid separation, reduces the emission of waste liquid and exhaust gas, and reduces the impact on the environment. At the same time, by absorbing heat from the coolant through the fermentation liquid, the condenser 604 can quickly cool the coolant, reducing the energy consumption of the condenser 604.

[0039] This invention features a flow-limiting component 9. The compressor 802 creates a pressure difference for the exhaust gas, causing the exhaust gas to push the flow-limiting plug 904 and the tension spring 903 to move. This prevents the flow-limiting plug 904 from blocking the flow-limiting ring 902, allowing the exhaust gas to pass through the flow-limiting ring 902 and enter the gas storage tank 801 for compression and storage. After the distillation process is complete, the compressor 802 stops working, and the pressure of the compressed exhaust gas in the gas storage tank 801 is greater than the external pressure. At the same time, the spring 903 automatically contracts, causing the flow-limiting plug 904 to block the flow-limiting ring 902, preventing the exhaust gas from flowing back. This allows workers to directly release organic matter from the liquid outlet pipe 10 at the lower end of the condenser shell 4 without worrying about exhaust gas leakage.
