Description

A spiral reactor

technical field

The utility model relates to the field of chemical equipment, in particular to a spiral reaction kettle.

Background technique

The reactor is a comprehensive reaction vessel, and the structure, function and configuration accessories of the reactor are designed according to the reaction conditions. From the initial feeding-reaction-discharging, the preset reaction steps can be completed with a high degree of automation, and the temperature, pressure, mechanical control (stirring, blasting, etc.), reactants/products during the reaction process Important parameters such as concentration are strictly regulated. Its structure is generally composed of kettle body, transmission device, stirring device, heating device, cooling device and sealing device. Corresponding supporting auxiliary equipment: fractionation column, condenser, water separator, collection tank, filter, etc.

In the gas-liquid reaction device, in order to fully contact the gas and the liquid, the gas is generally introduced from the bottom and the liquid is passed from the top; but in the existing reactor, the gas and the liquid cannot be fully mixed. In particular, the liquid diffuses to the top more slowly, resulting in a less uniform reaction.

Utility model content

Aiming at the problems existing in the prior art, the utility model provides a spiral reaction kettle, which uses the stirring spiral extending from the bottom to rapidly diffuse the gas to the top of the liquid, mix the two evenly, fully contact the reaction, and improve the qualification of the product Rate.

The concrete technical scheme that the utility model adopts is as follows:

A spiral reactor, comprising a reactor body, the top of the reactor body is provided with a liquid feeding port, and the bottom is a flat bottom;

A gas distribution pipe extending into the bottom of the reaction kettle body is provided, and a first gas channel and a second gas channel are arranged in the gas distribution tube, as well as an air outlet communicating with the first gas channel and the second gas channel;

The bottom of the reactor body is equipped with a drive motor connected with a stirring screw extending into the reactor body;

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 gas mixed and reacted with the liquid are introduced through the first gas channel and the second gas channel in the gas distribution pipe, and under the action of the spoiler and the stirring screw, they diffuse upward quickly and fully mix with the liquid. contact reaction.

The spoiler is kept parallel to the stirring spiral, but is kept inclined to the inner wall of the kettle, and the angle is between 30° and 60°, 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 space to enhance the fluidity of the liquid.

In order to maintain the fluidity of the diffused gas and liquid, preferably, a motor is installed on the top of the reactor body, and a stirring blade extending into the reactor body is connected.

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.

As preferably, the air distribution pipe is connected to the air inlet joint outside the reactor body, 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 and reasonable design. The gas is quickly diffused to the top of the liquid by using the stirring screw extending from the bottom, and the two are evenly mixed, fully contacted and reacted, and the qualified rate of the product is improved.

Figure 2 is a cross-sectional view of the air distribution pipe.

Detailed ways

The utility model is described in detail below in conjunction with embodiment and accompanying drawing, but the utility model is not limited thereto.

The spiral reactor shown in Figure 1 and Figure 2 includes a reactor body 1, the top of which is provided with a liquid feeding port 2, and the bottom is a flat bottom; 10. The gas distribution pipe 10 is provided with a first gas channel 14 and a second gas channel 15, and an air outlet 16 communicating with the first gas channel 14 and the second gas channel 15; the bottom of the reactor body 1 is equipped with a drive motor 7 The driving motor 7 is connected with a stirring screw 8 protruding into the reactor body 1; the middle inner wall of the reactor body 1 is provided with 4 to 8 spoilers 6 at intervals.

In this embodiment, two kinds of gas mixed and reacted with the liquid are introduced through the first gas channel and the second gas channel in the gas distribution pipe 10, and under the action of the spoiler 6 and the stirring screw 8, they diffuse upward quickly and fully mix with the liquid. Mixed contact reactions.

The spoiler 6 is kept parallel to the stirring screw 8, but is kept inclined with the inner wall of the kettle, and the angle is between 30 and 60 degrees, so as to speed up the mixing of liquid and gas. In order to prevent the liquid from staying between the spoilers, the length of the spoilers should be set reasonably. For example, the height of the spoiler 6 is 1/5-1/3 of the reactor body 1, so that the upper and lower parts of the spoiler are left There is space to enhance the fluidity of the liquid.

In order to maintain the fluidity of the diffused gas and liquid, a motor 3 is installed on the top of the reactor body 1, and a stirring shaft 4 and a stirring blade 5 extending into the reactor body are connected.

In order to provide the temperature required for the reaction, at least one side surface of the spoiler 6 is provided with a heating coil 9 to heat the gas and liquid in the reactor.

The air distribution pipe 10 is connected with the air inlet joint 11 outside the reactor body, the air inlet joint 11 is provided with a first air inlet 12 and a second air inlet 13, and the gas enters two gas passages respectively through the two air inlets, Finally diffused into the reactor.
