Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the reaction device with a liquid level control function comprises a reaction kettle 3 with a feed inlet 1 at the top and a discharge outlet 2 at the bottom, wherein a stirrer 4 is arranged in the reaction kettle 3, the reaction device also comprises a head tank 5 positioned above the reaction kettle 3, the top of the head tank 5 is provided with a feed pipe 6, an exhaust pipe 7 and a communicating pipe 8, the bottom of the head tank 5 is provided with a discharge pipe 9, and the other end of the discharge pipe 9 is connected with the feed inlet 1; three communicating branch pipes 10 are arranged on the side wall of the reaction kettle 3 at equal intervals from top to bottom, and the other ends of the three communicating branch pipes 10 are communicated with a communicating pipe 8; the feeding pipe 6, the exhaust pipe 7, the discharging pipe 9 and the communicating branch pipe 10 are all provided with valves.
Of the three communicating branch pipes 10, the height at the highest position is lower than the designed maximum height of the liquid level in the reaction kettle 3, and the height at the lowest position is higher than the designed minimum height of the liquid level in the reaction kettle 3. Among the three communicating branch pipes 10, one end of the communicating branch pipe 10 located at the highest position is connected with 2/3 of the height of the side wall of the reaction kettle 3, one end of the communicating branch pipe 10 located at the middle position is connected with 1/2 of the height of the side wall of the reaction kettle 3, and one end of the communicating branch pipe 10 located at the lowest position is connected with 1/3 of the height of the side wall of the reaction kettle 3.
The three communicating branch pipes 10 are spaced at intervals of 0.1-1.0 m.
In order to facilitate discharging, the discharging port 2 is connected with a discharging pipe 11, and a valve is arranged on the discharging pipe.
When the liquid level control device is used, only one valve on the three communicating branch pipes 10 is opened, and the valves on the other two communicating branch pipes 10 are closed so as to control the liquid level height. And opening a valve on the discharge pipe 9, enabling the liquid material to enter the reaction kettle 3 from the elevated tank 5, and continuously raising the liquid level in the reaction kettle 3. If the valve on the communication branch pipe 10 at the highest position is opened and the valves on the other two communication branch pipes 10 are closed, when the liquid level in the reaction kettle 3 exceeds the height of the communication branch pipe 10 at the highest position, the gas in the reaction kettle 3 cannot enter the high-level tank 5 through the communication branch pipe 10 and the communication pipe 8, so that the gas pressure in the high-level tank 5 is low, the liquid cannot continuously flow into the reaction kettle 3, namely the liquid in the reaction kettle 3 reaches the set position and then the feeding is stopped. Similarly, if the valves on the communication branch pipes 10 at the middle position are opened and the valves on the other two communication branch pipes 10 are closed, the feeding is automatically stopped when the liquid level reaches the height of the communication branch pipe 10 at the middle position and the liquid level in the reaction kettle 3 reaches the set position. The utility model discloses simple structure, convenient operation can the automatic shutdown liquid feeding, and this reactor both can be used for intermittent type reaction, also can be used for continuous reaction.
When the utility model is used as a batch reactor, the adding and liquid level control process of the materials is as follows: closing valves on the feeding pipe 6 and the exhaust pipe 7, and closing a valve on the discharging pipe 11; when the liquid level in the reaction vessel 3 is determined, for example, when the feeding amount is determined to be half of the volume of the reaction vessel 3, the valve on the communication branch pipe 10 in the middle position is opened, the valves on the other two communication branch pipes 10 are closed, and then the valve on the discharging pipe 9 is opened to start feeding. When the liquid level in the reaction vessel 3 exceeds the height of the communicating branch pipe 10 at the intermediate position, the gas in the reaction vessel 3 cannot enter the head tank 5 from the communicating branch pipe 10 and the communicating pipe 8. As the liquid in head tank 5 continues to flow into reaction vessel 3, the pressure in head tank 5 becomes lower than that in reaction vessel 3, causing the liquid in head tank 5 to stop flowing into reaction vessel 3. The liquid level in the reaction kettle 3 can be controlled by changing the switching states of the three communicating pipe branch pipes 10.
