Description

Technical Field

[0001] This application relates to the technical field of resin reaction, and particularly to a reaction chamber of a chain plate type polymerization reaction device. Background Art

[0002] Resin generally refers to an organic polymer that softens or has a melting range when heated, has a tendency to flow under the action of external force when softened, and is solid, semi-solid, or sometimes liquid at normal temperature. Broadly defined, any high molecular compound that can be used as a processing raw material for plastic products is called resin. The relative molecular weight of resin is uncertain but usually high. It is a solid, medium-solid, or pseudo-solid organic substance at normal temperature, and sometimes can also be liquid. It is usually a polymer or prepolymer used as a plastic substrate.

[0003] In related technologies, in the production process of superabsorbent resin SAP, the chain plate type polymerization reaction device is a commonly used polymerization device in the production of superabsorbent resin. When the neutralized liquid enters the reaction zone, polymerization reaction starts under the action of initiator, ultraviolet (or temperature), etc. To ensure the normal progress of the reaction, it is necessary to discharge the reaction liquid water vapor in the reaction chamber in the early stage to prevent the condensation of the reaction liquid water vapor from dripping on the gel. In the middle stage, it is necessary to keep the gel warm, and in the later stage, it is necessary to cool the gel to meet the requirements of crushing. Therefore, the control of the temperature and humidity in the reaction chamber of the chain plate type polymerization reaction device is a major factor in whether high-quality superabsorbent resin can be produced. For this reason, we have improved the design of the reaction chamber of the original chain plate polymerization reaction device to meet the reaction requirements of superabsorbent resin.

[0029] An embodiment of the present application discloses a reaction chamber of a chain plate type polymerization reaction device. Referring to Figure 1 , it includes a reaction zone 1, a heat preservation zone 2, and a cooling zone 3. The heat preservation zone 2 is located between the cooling zone 3 and the reaction zone 1. An exhaust fan 31 is provided at the top of the cooling zone 3. Three air inlets 32 are spaced apart on one side wall of the cooling zone 3. A cooling fin tube 33 is connected to any one of the air inlets 32. By controlling the amount of cooling water in the cooling fin tube 33 and the air volume of the exhaust fan 31, the temperature of the gel body is ensured to meet the process requirements, thereby improving the cooling efficiency of the cooling zone 3. Air supply openings 9 are provided on both the heat preservation zone 2 and the reaction zone 1. The air inlets 32 and the air supply openings 9 are at the same height, which is convenient for the consistency of the product structure in actual production, making the structure more compact and beautiful.

[0030] In order to facilitate the control of the temperature and humidity in the heat preservation zone 2 and the reaction zone 1, arc domes 4, exhaust openings 5, and variable frequency fans 6 connected to the exhaust openings 5 are provided on both the reaction zone 1 and the heat preservation zone 2. Butterfly valves 7 that can be manually adjusted are provided on the sides of the reaction zone 1 and the heat preservation zone 2. The butterfly valves 7 are set to be manually adjustable, which is convenient for the staff to adjust the air intake volume of the reaction zone 1 and the heat preservation zone 2 according to the actual working conditions.

[0031] A steam tracing pipe 8 is provided above any one of the arc domes 4. Temperature and humidity detection components are provided in both the heat preservation zone 2 and the reaction zone 1. In the embodiment of the present application, the temperature and humidity components include a temperature sensor and a dew point sensor. The installation positions and specific models of the temperature sensor and the dew point sensor are not limited.

[0032] The temperature sensor and the dew point sensor respectively detect the temperature and humidity in the heat preservation zone 2 and the reaction zone 1 and output temperature detection signals and humidity detection signals.

There are two connecting plates 42, which are respectively connected to both sides of the arc plate 41. The arc top of the arc plate 41 is arranged close to the top of the heat preservation zone 2. A heat preservation board 21 is arranged on the side wall of the heat preservation zone 2, and one end of the connecting plate 42 away from the arc plate 41 is connected to the heat preservation board 21. Compared with a flat top, the combination of the arc top and the heat preservation board 21 is convenient for gathering temperature, thereby further improving the heat preservation effect.

[0035] Refer to Figure 3 , the connecting plate 42 of the arc dome 4 in the reaction zone 1 is closely attached to the side wall of the reaction zone 1, and a condensation diversion groove 43 is formed at the end of the connecting plate 42. Compared with a flat top, it is convenient for the concentration of condensation in the reaction zone 1 and for collecting the condensation.
