Detailed Description

The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, a stirring reaction apparatus disclosed in the present application includes a non-metal mixing tank 11, an air chamber 12, a first aeration pipe 13, a second aeration pipe 14, a feeding pipe 15, a condensing exhaust pipe 16, a driving device 17, and the like, wherein the top end of the non-metal mixing tank 11 is an open end, and in some possible implementations, the non-metal mixing tank 11 is made of a fiber reinforced composite material.

The gas chamber 12 is placed on the non-metallic mixing tank 11, and one of them is used to close the open top end of the non-metallic mixing tank 11, and a graphite gasket or a stainless steel reinforced graphite gasket is installed at the joint of the two, as shown in fig. 3. The power for the rotation of the air chamber 12 is provided by a driving device 17.

Hot-air generators (e.g. electric hot-air generators and gas hot-air generators) are connected by a duct to a lead-in pipe (shown in fig. 1) in the centre of the chamber 12, the connection being made using a mechanical seal.

In some possible implementations, the driving device 17 is composed of a driving group (including a motor and a reducer) and a gear installed on the output end of the driving group, and a gear ring is installed on the side wall of the air chamber 12 and is engaged with the gear ring. When the driving means 17 is activated, the air chamber 12 is slowly rotated.

The first end of the first aeration pipe 13 is connected to the air chamber 12, and the second end extends in a direction away from the air chamber 12. The first aeration pipe 13 has two functions, the first is to inject hot air into the nonmetal mixing tank 11 to heat the mixture in the nonmetal mixing tank 11, and the second is to stir the mixture in the nonmetal mixing tank 11.

In some possible implementations, the number of the first aeration pipes 13 is plural and the first aeration pipes are distributed uniformly on the air chamber 12.

Referring to fig. 4, a wing 131 is further added to the first aeration pipe 13, and the wing 131 is not parallel to the moving direction of the first aeration pipe 13, and is used to enlarge the affected area of the first aeration pipe 13 during rotation, which is helpful to improve the stirring effect.

The feed pipe 15 is established on nonmetal blending tank 11, and the effect is to throwing the raw materials that the reaction needs in nonmetal blending tank 11, and the quantity of feed pipe 15 can be one, also can be a plurality of.

The condensation exhaust pipe 16 has an input end, a gas output end and a return end, the input end and the return end are both connected with the nonmetal mixing tank 11, and the gas output end is connected with the tail gas treatment equipment. The condensation exhaust pipe 16 serves to recover the raw material or the mixture in the air discharged from the nonmetal mixing tank 11.

It should be understood that, during the heating, mixing, stirring and the like of the non-metal mixing tank 11, the pressure in the non-metal mixing tank 11 will gradually increase with the injection of the hot air, and at this time, a part of the gas in the non-metal mixing tank 11 needs to be discharged. However, in a high temperature environment, a part of the mixture in the non-metal mixing tank 11 exists in the air in the metal mixing tank 11 in a liquid state and/or a small-particle-size solid state.

After this air flows into the condensing exhaust pipe 16, the doped mixture therein will change from a new liquid state to a liquid state and flow back into the non-metal mixing tank 11, and if there are small-particle solid substances, these small-particle solid substances will be captured by the liquid state formed during the condensation process. That is, the main function of the condensing exhaust pipe 16 is to increase the utilization rate of the raw material and to reduce the load on the subsequent tail gas treatment equipment.

On the whole, the stirring reaction device that this application provided can mix, acidize and stir at nonmetal blending tank 11, and the integrated level of production improves by a wide margin, has both left out the material and has circulated among each equipment in original production mode, has reduced the proportion of non-production time in total production time, has still solved the corruption and the leakage problem of circulation in-process.

The heating process is carried out by hot air, a large amount of bubbles formed by the hot air in the process of exchanging heat with the mixture in the nonmetal mixing tank 11 can also stir the mixture, the first aeration pipe 13 can also stir the mixture in the nonmetal mixing tank 11 in the rotating process, and both the mixture and the reaction can be more sufficient.

Referring to fig. 2, as an embodiment of the stirring reactor provided in the application, a second aeration pipe 14 is added, and a first end of the second aeration pipe 14 is connected to the air chamber 12, and a second end extends along the inner wall of the non-metal mixing tank 11 in a direction away from the air chamber 12.

The second aeration pipe 14 has the same function as the first aeration pipe 13, except that the second aeration pipe 14 is closer to the inner wall of the nonmetal mixing tank 11, so that the heating and stirring in the nonmetal mixing tank 11 can be more sufficient.

Further, the number of the second aeration tubes 14 is plural and is uniformly arranged around the axis of the air chamber 12.

Referring to fig. 5, as a specific embodiment of the stirring reactor provided by the application, the condensing exhaust pipe 16 is composed of a reflux chamber 161, an input pipe 162, a condensing chamber 163, a condensing pipe 164, a reflux pipe 165, and the like, and both ends of the input pipe 162 are respectively connected to the nonmetal mixing tank 11 of the reflux chamber 161, and are used for introducing the high-temperature gas in the nonmetal mixing tank 11 into the reflux chamber 161.

The condensing chamber 163 is disposed on the reflow chamber 161, a first end of the condensing pipe 164 is connected to the reflow chamber 161, and a second end of the condensing pipe passes through the condensing chamber 163 and is connected to the tail gas treatment device. When the high-temperature gas in the reflow chamber 161 flows into the condensing duct 164, moisture and a part of the substances contained in the high-temperature gas are condensed on the inner wall of the condensing duct 164 and become liquid again.

This portion of the liquid material will flow into the return chamber 161 and then back to the non-metallic mixing tank 11 through the return conduit 165. The cold water of the condensing chamber 163 circulates, so that the moisture and a part of the substances contained in the high temperature gas can be condensed on the inner wall of the condensing duct 164 again.

Furthermore, the input pipe 162 is connected with the side surface of the return chamber 161, and the condensation pipe 164 is connected with the bottom surface of the return chamber 161, so that the high-temperature gas flowing into the return chamber 161 can rapidly flow into the condensation pipe 164 without being influenced by the liquid dripping or remaining from the condensation pipe 164, and the liquid can rapidly flow back into the nonmetal mixing tank 11 through the return pipe 165 without being retained in the return chamber 161.

Further, the portion of the condensing duct 164 located in the condensing chamber 163 is formed in a spiral shape, so that the length of the portion of the condensing duct 164 located in the condensing chamber 163 can be increased, the heat exchange contact area between the high-temperature gas and the condensing duct 164 can be increased, and the condensing efficiency of the condensing duct 164 can be improved.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
