Description

Technical Field

[0001] This utility model relates to the field of reactor ventilation devices, specifically to a multi-point ventilation device. Background Technology

[0002] In the production of water-soluble polyacrylamide polymer emulsions, nitrogen gas is typically introduced through the bottom of the reactor for oxygen removal. Dissolved oxygen in the system inhibits polymerization; nitrogen replaces this oxygen, ensuring rapid polymerization initiation. Furthermore, the viscosity and molecular weight of the system increase steadily under nitrogen protection, achieving the desired product specifications. Traditional nitrogen introduction involves introducing nitrogen through one or two pipelines at the bottom of the reactor, where it mixes with the materials under stirring to achieve oxygen removal. However, this method suffers from uneven mixing due to the unidirectional nitrogen flow, leading to abnormal polymerization or slow polymerization rates, thus affecting the final product quality.

[0003] Therefore, in order to solve the above-mentioned problems, a multi-point ventilation device is proposed. Utility Model Content

[0004] This invention addresses the problems mentioned above by designing a multi-point ventilation device. This device can significantly improve the oxygen removal effect inside the reactor by introducing multiple nitrogen gas into the pipeline. At the same time, the flow direction adjustment device allows the nitrogen gas to flow freely in multiple directions, improving the mixing degree between the nitrogen gas and the internal gas after entering the reactor, thus enhancing the oxygen removal effect.

[0005] To achieve the above objectives, this utility model provides a multi-point ventilation device, comprising a reactor shell, an inlet pipe, an outlet pipe, and a flow direction adjustment device. The inlet pipes are multiple in number, connected to the bottom of the reactor shell and communicating with its interior. The outlet pipes are connected to the top of the reactor shell and communicating with its interior. The flow direction adjustment device is detachably connected to the end of the inlet pipes and located inside the reactor shell.

[0006] In this way, nitrogen is introduced into the bottom through multiple air inlet pipes. When the nitrogen passes through the outlet of the air inlet pipe, it flows through the flow direction regulating device. The flow direction regulating device can disperse the nitrogen into the reactor in multiple directions, which can make the gas introduction more uniform and mix more evenly with the internal system materials.

[0007] Furthermore, the flow direction adjustment device includes a quick-connect part and an adjustment part. The quick-connect part has a cylindrical structure, and the adjustment part is detachably connected to the top of the quick-connect part. The bottom of the quick-connect part is inserted into the end of the air inlet pipe located inside the outer shell of the reactor.

[0008] Through the above methods, the quick-installation unit enables convenient installation and removal of the flow direction adjustment device, facilitating the modification of other types of reactors and improving the versatility of the device.

[0009] Furthermore, the quick-installation part includes a connector and a main body, both of which are cylindrical structures and are integrally formed. The diameter of the connector is smaller than the diameter of the main body. The connector is inserted into the end of the air intake pipe, and the adjustment part is detachably connected to the upper part of the main body.

[0010] Furthermore, the adjusting part includes: a fixing sleeve, a thrust bearing, a guide plate, and a fixing buckle. The fixing sleeve is fitted onto the top of the quick-release part. The bottom surface of the thrust bearing is fixedly connected to the fixing sleeve. The bottom of the guide plate is fixedly connected to the top surface of the thrust bearing. The fixing buckle has a right-angle structure. The bottom of the fixing buckle is fixedly connected to the fixing sleeve, and the upper part of the fixing buckle covers the thrust bearing.

[0011] Furthermore, there are two guide plates, with the bottoms of the two guide plates symmetrically arranged on the thrust bearing with the axis of the circular upper surface of the thrust bearing as the axis of symmetry, and the tops of the two guide plates being far apart from each other.

[0012] In this manner, the two guide plates are located at the three equal divisions of the top opening, and each forms an acute angle of 45° with the outlet plane. This divides the nitrogen gas entering from the outlet and diffuses it in both directions, making the mixing more uniform. The guide plates can also rotate via thrust bearings. The thrust bearings receive the force of the gas thrust and the force of internal stirring. When the thrust bearings rotate, they can drive the guide plates to more angles, making the gas mixing more uniform.

[0013] Furthermore, it also includes an oxygen detector, which is installed on the outlet pipe.

[0014] In summary, this utility model has the following advantages and beneficial technical effects:

[0015] 1. This utility model provides a multi-point ventilation device that can significantly improve the oxygen removal effect inside the reactor by introducing multiple nitrogen gas into the pipeline;

[0016] 2. The present invention provides a multi-point ventilation device that utilizes the guide plate of the flow direction adjustment device to allow nitrogen to flow freely in multiple directions, thereby improving the mixing degree of the internal gas after the nitrogen enters the reactor and enhancing the oxygen removal effect.

[0017] 3. The multi-point ventilation device of this utility model has a thrust bearing installed below the guide plate, which can drive the guide plate to rotate and discharge nitrogen in more directions, thereby improving the mixing degree. Attached Figure Description
