The impact flow reactor, the premixed two-stage impact flow reactor includes two first-stage impact flow reactors, and the two first-stage impact flow reactors communicate through the first T-shaped impact nozzle, and the first T-shaped impact flow reactor In communication with the kettle body, the first-stage impingement flow reactor includes a material pipeline, and the material pipeline communicates through a second T-shaped impact nozzle.

A safety valve is arranged on the kettle body, a discharge port is arranged on the top of the kettle body, and temperature sensors and pressure sensors are arranged on both sides of the kettle body.

The stirring paddle is coated with silicon carbide coating, the angle between the blade of the turbine paddle and the horizontal plane is 40-60 degrees, and the length of the blade of the choke paddle is 1/2-9/10 of the internal diameter of the kettle. The stirring motor is a variable frequency motor.

The premixed two-stage impingement flow reactor is arranged on the bottom side wall of the kettle body, and the tees of the first T-shaped impact nozzle and the second T-shaped impact nozzle are both provided with tapered openings.

The beneficial effects of the utility model:

1. A high-efficiency reaction kettle for gas fire extinguishing agent of the present utility model, the raw materials are pre-mixed evenly, and the mixing efficiency is high. The impingement mixing is carried out through the first-stage impingement flow reactor, and then the impinging mixture and the two-stage impingement pre-mixing greatly improve the uniformity of gas mixing. At the same time, there are two layers of stirring paddles, the upper layer is a turbine paddle, and the lower layer is a choke paddle. The mixing and stirring of the two layers also greatly improves the mixing efficiency and improves the reaction efficiency.

2. Continuous production can be realized, because the pre-mixing stage is very sufficient, and the impingement flow reactor also strengthens the mixing and reaction, thereby shortening the reaction time, and most of the reaction is completed in the pre-mixing stage. Mix and react, and then discharge from the discharge port on the top of the kettle body, realizing continuous reaction.
