Description

Technical Field

[0001] This utility model belongs to the field of fermenter exhaust gas treatment, specifically relating to a 50L fermenter exhaust gas treatment device. Background Technology

[0002] A 50L fermenter is a laboratory or small-to-medium-sized production equipment widely used in fields such as bioengineering, pharmaceuticals, and food brewing. It is mainly used for processes such as microbial culture and fermentation reactions.

[0003] To reduce costs, most fermenter manufacturers use relatively simple treatment methods when installing exhaust gas treatment systems, such as simple condensation recovery. These traditional systems have significant drawbacks:

[0004] Firstly, there is a lack of effective monitoring and control mechanisms for exhaust gas pressure. During fermentation, the pressure inside the tank changes dynamically with the fermentation process. If the exhaust gas treatment device cannot adapt to the pressure changes in time, and exhaust cannot be performed in case of an abnormality, the tank pressure of the fermenter will rise sharply, which means that fermentation must be stopped, leading to the failure of the fermentation experiment.

[0005] Secondly, the connections between the various components of the device are mostly fixed connections, which makes it very inconvenient to operate when it is necessary to repair or replace the equipment, and consumes a lot of time and manpower.

[0006] Therefore, corresponding improvements were made to address the shortcomings of the existing 50L fermenter exhaust gas treatment device. Utility Model Content

[0007] In view of the problems of traditional exhaust gas treatment devices, such as the lack of an effective monitoring and control mechanism for exhaust gas pressure and the fact that the connection between the various components of the device is mostly fixed and not easy to disassemble, this utility model provides an exhaust gas treatment device for a 50L fermenter.

[0008] The solution adopted by this utility model to solve its technical problem is: a 50L fermenter exhaust gas treatment device, including a condenser, a diversion pipe, a spare pipe and a recovery pipe. A pressure gauge and a pressure sensor are installed on the diversion pipe, and a left interface, a middle interface and a right interface are provided at its bottom.

[0009] The upper and lower ports of the condenser are detachably connected to the exhaust pipe of the fermenter and the right side interface of the diversion pipe via a connector.

[0010] A solenoid valve is installed on the recovery pipe, and its upper end is detachably connected to the left side interface of the diversion pipe via connector three.

[0011] The pressure sensor is electrically connected to the solenoid valve and controls the opening and closing of the solenoid valve based on the detected pressure signal.

[0012] One end of the spare tube is detachably connected to the middle interface of the diversion tube via connector two, and the other end is connected to the recovery tube. A pressure manual control valve is installed on the spare tube.

[0013] Preferably, the first connector, the second connector, and the third connector are quick-install clamp one, quick-install clamp two, and quick-install clamp three, respectively.

[0014] Preferably, the solenoid valve is a normally closed solenoid valve.

[0015] Preferably, the diversion pipe, the backup pipe, and the recovery pipe are all made of stainless steel.

[0016] Preferably, the condenser is a water-cooled condenser.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model achieves real-time monitoring and automatic adjustment of exhaust gas pressure by integrating a pressure gauge and a pressure sensor into a shunt pipe, combined with the linkage control of a normally closed solenoid valve. When the pressure is normal, the solenoid valve remains closed, and the exhaust gas enters the condenser for condensation and recovery. When the pressure exceeds the set threshold, the solenoid valve automatically opens to release pressure, thereby effectively preventing the fermenter from becoming too pressurized, avoiding fermentation failure, and ensuring the smooth progress of the fermentation experiment.

[0019] 2. This utility model forms a backup exhaust channel by setting up a backup pipe and a manual pressure valve, and with the pressure gauge on the diversion pipe, it can quickly release pressure through manual intervention in the event of failure of the solenoid valve or pressure sensor or power interruption, forming a "automatic + manual" dual insurance mechanism, which greatly reduces the risk of equipment failure.

[0020] 3. This utility model achieves rapid disassembly and assembly between the condenser, the distributor pipe, the recovery pipe, and the spare pipe by using connector one, connector two, and connector three, which facilitates the inspection or replacement of components. The operation is simple and convenient, greatly reducing the required time and labor costs, significantly improving the efficiency of equipment maintenance, and reducing the difficulty of equipment maintenance.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 This utility model provides a technical solution for a 50L fermenter exhaust gas treatment device:

[0025] Example 1:

[0026] according to Figure 1 As shown, it includes a condenser 2, a manifold 4, a spare pipe 7, and a recovery pipe 10. A pressure gauge 5 and a pressure sensor 11 are installed on the manifold 4. The pressure gauge 5 is used to visually display the pressure inside the manifold 4, which is convenient for operators to observe and monitor. The pressure sensor 11 is used to detect the pressure change inside the manifold 4 in real time and convert the pressure signal into an electrical signal, which is then transmitted to the control system.

[0027] The bottom of the diversion pipe 4 is provided with a left-side interface, a middle interface and a right-side interface. The condenser 2 is a water-cooled condenser 2, which is used to cool and condense the exhaust gas generated during the fermentation process. The two ports of the condenser 2 are detachably connected to the exhaust pipe of the fermentation tank 1 and the right-side interface of the diversion pipe 4 respectively through connector 3.

[0028] A solenoid valve 9 is installed on the recovery pipe 10. Its upper end is detachably connected to the left interface of the diversion pipe 4 via connector 3 12. The solenoid valve 9 is a normally closed solenoid valve. The pressure sensor 11 is electrically connected to the solenoid valve 9 and controls the opening and closing of the solenoid valve 9 according to the detected pressure signal, realizing real-time monitoring and automatic adjustment of the exhaust gas pressure. When the pressure is normal, the solenoid valve 9 remains closed and the exhaust gas enters the condenser 2 for condensation and recovery. When the pressure exceeds the set threshold, the solenoid valve 9 automatically opens to release pressure, thereby effectively preventing the tank pressure of the fermenter 1 from being too high, avoiding the problem of fermentation failure, and ensuring the smooth progress of the fermentation experiment.

[0029] One end of the backup pipe 7 is detachably connected to the middle interface of the diversion pipe 4 via connector 2 6, and the other end is connected to the recovery pipe 10. A pressure manual control valve 8 is installed on the backup pipe 7. By setting the backup pipe 7 and the manual pressure valve to form a backup exhaust channel, and in conjunction with the pressure gauge 5 on the diversion pipe 4, pressure can be quickly released by manual intervention in the event of failure of the solenoid valve 9 or pressure sensor 11 or power interruption, forming a "automatic + manual" dual insurance mechanism, which greatly reduces the risk of equipment failure.

[0030] In practical use, the exhaust gas treatment device for a 50L fermenter of this utility model first starts the fermenter 1 to begin the fermentation process, and at the same time turns on the control system of the exhaust gas treatment device, observes the pressure gauge 5, and understands the initial pressure in the diversion pipe 4.

[0031] Pressure sensor 11 detects the pressure change in the diversion pipe 4 in real time and transmits the pressure signal to the control system. When the pressure in the diversion pipe 4 is normal, the solenoid valve 9 remains closed. The exhaust gas generated during fermentation enters the condenser 2 for cooling and condensation recovery. If the pressure in the diversion pipe 4 exceeds the set threshold, pressure sensor 11 transmits the signal to the control system. The control system issues a command to automatically open the solenoid valve 9 to release pressure, effectively preventing the pressure in the fermenter 1 from being too high and ensuring the smooth progress of the fermentation experiment. When the pressure drops to the normal range, the solenoid valve 9 automatically closes.

[0032] In case of failure of solenoid valve 9 or pressure sensor 11, or power interruption, observe pressure gauge 5. When the pressure exceeds the normal range, open pressure manual control valve 8 on standby pipe 7 to manually release pressure. Observe the pressure change in diversion pipe 4 through pressure gauge 5, and control the opening and closing of pressure manual control valve 8 according to the actual situation to ensure stable pressure in fermenter 1.

[0033] Example 2:

[0034] Based on Example 1, such as Figure 1 As shown, connector 1 (3), connector 2 (6), and connector 3 (12) are quick-install clamp 1, quick-install clamp 2, and quick-install clamp 3, respectively. By using connector 1 (3), connector 2 (6), and connector 3 (12), quick disassembly and assembly between condenser 2, distributor pipe 4, recovery pipe 10, and spare pipe 7 can be achieved, which facilitates the inspection or replacement of components. The operation is simple and convenient, greatly reducing the required time and labor costs, significantly improving the efficiency of equipment maintenance, and reducing the difficulty of equipment maintenance.

[0035] Diverter pipe 4, spare pipe 7, and recovery pipe 10 are all made of stainless steel.
