The middle inner wall of the reactor body is provided with 4 to 8 spoilers at intervals, and the height of the spoilers is 1/5 to 1/3 of the reactor body.

In the utility model, two kinds of gases mixed and reacted with the liquid are fed through the first gas channel and the second gas channel in the gas distribution pipe, and fully mixed and contacted with the liquid under the action of the spoiler and the stirring shaft.

The spoiler is kept parallel to the stirring shaft, but kept inclined to the inner wall of the kettle at an angle of 30-60 degrees, so as to speed up the mixing of liquid and gas.

In order to prevent the liquid from staying between the baffles, the length of the baffles should be set reasonably, for example, the height of the baffles is 1/5-1/3 of the reactor body, so that the upper and lower parts of the baffles are left There is room to enhance the fluidity of the liquid.

In order to provide the temperature required for the reaction, preferably, at least one side surface of the spoiler is provided with a heating coil to heat the gas and liquid in the reactor.

Preferably, a stirring blade is provided on the upper part of the stirring shaft, and a stirring plate is connected to the bottom.

Preferably, a stirring rod is connected to the top surface and the bottom surface of the stirring plate.

In order to keep the liquid in the upper part and the lower part of the reactor stirred at the same time, and accelerate the gas to diffuse rapidly from the bottom to the upper part of the reactor, a stirring mechanism is provided on the upper part and the lower part of the stirring shaft.

As preferably, the gas distribution pipe is connected to the air inlet joint outside the reactor body, and the air inlet joint is provided with a first air inlet and a second air inlet, and the gas enters two air inlets respectively through the two air inlets. The gas channel eventually diffuses into the reactor.

The utility model has the advantages of simple structure, practicality and convenience, which can mix the gas and the liquid fed into the bottom evenly, fully contact and react, and improve the qualified rate of the product.
