Aug 26, 2019

Before the reactor

1. Check whether the agitator, conversion part, subordinate equipment, indicating instrument, safety valve, pipeline and valve in the kettle can meet the requirements.

2. Check whether water, electricity and gas can meet the requirements.

The reactor is working:

1. Before the feeding, the stirrer of the reaction kettle should be opened first. When there is no noise and normal, the material is added to the reaction kettle. The number of feeds must not exceed the process requirements.

2. Before opening the steam valve, first open the air valve and then open the air inlet valve. Open the steam valve should be slow, so that it preheats the jacket, gradually increase the pressure, and the pressure inside the jacket is prohibited from exceeding the rule value.

3, the steam valve and the cooling valve can not be activated, the steam line is prohibited from hammering and collision.

4. When opening the cooling water valve, first open the water valve and then open the water valve. The cooling water pressure should not be lower than 0.1 MPa, and should not be higher than 0.2 MPa.

5, water ring vacuum pump, you must first open the pump after the water supply, stop the pump, stop the pump and then stop the water, and should remove the water in the pump.

6. Check the operation status of the reactor at any time and find that the abnormality should be stopped.

After the reactor is finished

1. Stop stirring, cut off the power supply, and close all kinds of valves.

2. When shoveling the pot, it is necessary to cut off the power of the mixer, hang the warning sign, and set up personnel to monitor.

3. The stainless steel reaction kettle shall be inspected according to the requirements of the pressure vessel, and the inspection shall fail, and shall not be used.
