AI Technical Summary
The existing waste gas treatment devices in the succinic acid production process have low condensation efficiency, making it difficult to fully recover valuable substances such as succinic acid vapor.
It adopts a combination structure of medium-temperature condenser and low-temperature condenser, combined with jet assembly and guide design. Through the reciprocating motion of moving ring and sealing piston, the exhaust gas is alternately sprayed out at different positions, increasing the contact area and time with the condensing medium. It uses chilled water and liquid nitrogen or ethylene glycol low-temperature solution for condensation treatment.
It improves the condensation and recovery efficiency of pollutants such as succinic acid vapor in waste gas, enhances the uniformity and thoroughness of waste gas treatment, and achieves more efficient condensation and recovery.

Abstract
Claims
1. A waste gas treatment device for production of succinic acid, characterized by include: The system includes a medium-temperature condenser (10), a low-temperature condenser (20), and a conical baffle (30). The conical baffle (30) is located between the medium-temperature condenser (10) and the low-temperature condenser (20). Both the medium-temperature condenser (10) and the low-temperature condenser (20) are equipped with jet assembly (40). The jet assembly (40) includes a jet tube (41). The outer circumferential side of the jet tube (41) is provided with multiple sets of jet ports (42). The jet tube (41) is provided with multiple moving rings (43). The surface of the moving rings (43) is provided with a sealing piston (44). The multiple moving rings (43) are connected to the same connecting rod (45). The connecting rod (45) is connected to an external reciprocating power drive. The connecting rod (45) drives the multiple moving rings (43) to reciprocate between two adjacent jet ports (42), alternately ejecting gas from the two jet ports (42).
2. The apparatus for treating exhaust gas from succinic acid production according to claim 1, characterized by, The jet nozzle (42) is provided with a guide (46), which includes two guide plates (461). The guide plates (461) are fixedly connected to the surface of the jet nozzle (42) with an elastic block (462). When the connecting rod (45) drives the moving ring (43) and the sealing piston (44) to leave the corresponding jet nozzle (42) position, the airflow gradually increases, blowing the guide plate (461) to tilt and causing the airflow to diffuse and spray out.
3. The apparatus for treating exhaust gas from succinic acid production according to claim 1, characterized by, An air inlet pipe (11) is provided on one side of the medium-temperature condenser (10), and an air outlet pipe (21) is provided on the top of the low-temperature condenser (20). One of the jet nozzles (41) is connected to the air inlet pipe (11), and the other jet nozzle (41) is connected to the conical baffle (30).
4. The apparatus for treating exhaust gas from succinic acid production according to claim 1, characterized by, Both the bottom of the medium-temperature condenser (10) and the bottom of the low-temperature condenser (20) are provided with drain pipes (22), which are connected to external recovery equipment.
5. The waste gas treatment device for succinic acid production according to claim 1, characterized in that, The medium-temperature condenser (10) is equipped with a tube-type condenser, the cooling medium of which is chilled water. The low-temperature condenser (20) is equipped with a spiral plate condenser, the cooling medium of which is liquid nitrogen or ethylene glycol low-temperature solution.
