Embodiment 2
[0044] The method for microwave concentration of chemical raw materials using a chemical raw material microwave concentration device includes the following steps:
[0045] (1) Feeding: Add 1% of the dilute chemical raw materials into the reactor through the pump through the feed port 8. Turn on the bubble generating mechanism 5, so that the bubble generating mechanism 5 generates bubbles at the bottom of the reactor. The blast volume is 1m 3 / min, stir the chemical raw material solution in the reaction kettle through the impulse of bubbles, and set it aside;
[0046] (2) Concentration: The concentration step of the chemical raw materials to be used in step 1) is divided into one-step concentration and two-step concentration. In the one-step concentration, a microwave generator 3 is used to emit microwaves with a frequency of 300MHz into the chemical raw material solution and adjust The temperature of the solution is 40°C, microwave treatment is 30min; then the emission frequency of...
Embodiment 3
[0050] The method for microwave concentration of chemical raw materials using a chemical raw material microwave concentration device includes the following steps:
[0051] (1) Feeding: add 20% of the dilute chemical raw materials into the reactor through the pump from the feed port 8 and turn on the bubble generating mechanism 5 so that the bubble generating mechanism 5 generates bubbles at the bottom of the reactor. The blast volume is 6m 3 / min, stir the chemical raw material solution in the reactor through the impulse of bubbles, and set it aside;
[0052] (2) Concentration: The concentration step of the chemical raw materials to be used in step 1) is divided into one-step concentration and two-step concentration. In the one-step concentration, a microwave generator 3 is used to emit microwaves with a frequency of 3000 MHz into the chemical raw material solution and adjust The temperature of the solution is 60°C, microwave treatment for 1 min; then adjust the emission frequency ...
