Description

Technical Field

[0001] The utility model belongs to the technical field of reactors, and in particular relates to a high-temperature oxidation reaction anti-sintering reactor. Background Art

[0002] When calcining anthracite vanadium to extract alum, the oxidation temperature required is relatively high. In order to make the material react better, we use suspended calcination to carry out the material reaction. However, the material reaction temperature is relatively high. When it reaches 900℃, the material will become hardened, eventually sticking to the inner wall of the reactor and continuing to grow and spread. Ultimately, it cannot reach the suspended state and blocks the reactor, making the reactor unusable and delaying normal production tests.

[0003] Existing reactors, such as Figure 1 As shown, the feed chamber and the reaction chamber are both rectangular structures, the overall material is 310S, the operating conditions are 1100 high temperature, the outside is a heating system, and the heat is conducted from the outside to the chamber to heat the material, so that it reacts with the gas to achieve the purpose of purification. However, during use, when the material reaches 1100 degrees, the material will cause high-temperature sintering at the right angles of the reaction chamber and on the outer wall of the entire reaction chamber. The reason is that when the heat is conducted, the temperature of the outer wall will be higher than the temperature of the internal chamber when the material passes through the outer wall. When the internal chamber reaches the reaction temperature, the outer wall often has a higher temperature, and the stone coal vanadium material will sinter. Utility Model Content

[0008] The reaction chamber of the present invention is evenly distributed with multiple gas distribution cylinders around the outside, and the gas is uniformly introduced into the internal wind cap through the gas distribution cylinders. When the gas is introduced, the gas inside the reaction chamber can form a cyclone. The gas outlet direction in the gas cap is consistent, the gas moves in one direction, and the flow air chamber provides upward gas.

[0013] The present invention will be described in detail below with reference to the accompanying drawings.

[0014] like Figure 2-3As shown, a high-temperature oxidation reaction anti-sintering reactor includes a feed chamber 1 and a reaction chamber 2. The feed chamber 1 is connected to the reaction chamber 2. A feed port 10 is provided on the top of the feed chamber 1, and a discharge port 6 is provided on the top side of the reaction chamber 2; a loosening air chamber 3 is provided at the bottom of the feed chamber 1, and the wind in the loosening air chamber 3 will keep the material in a suspended state to prevent the material from directly accumulating and causing the material to be unable to flow; a flow air chamber 4 is provided at the bottom of the reaction chamber 2 to make the material in the reaction chamber 2 flow; the feed chamber 1 and the reaction chamber 2 are cylindrical structures, and a dome-shaped cap 5 is provided on the top of the reaction chamber 2 to prevent the material from accumulating on the inner wall and cap of the feed chamber 1 and the reaction chamber 2, and a plurality of gas distribution holes are evenly distributed around the outside of the reaction chamber 2. Cylinder 7, the bottom of the sub-cylinder 7 is connected to the air inlet pipe 8, and the gas enters the sub-cylinder 7 through the air inlet pipe 8. The gas can be evenly delivered to the reaction chamber 2 through the sub-cylinder 7, and due to the existence of the sub-cylinder 7, the temperature of the outer wall of the reaction chamber 2 and the internal chamber becomes closer, which indirectly increases the inlet temperature of the compressed air and saves resources; multiple holes are provided on the inner side of the multiple sub-cylinders 7 from top to bottom, and the positions of the holes on each sub-cylinder 7 are consistent. Wind caps 9 are set at the holes, and the air outlet directions of the multiple wind caps 9 are consistent. The air outlet direction of the wind caps is opened in a clockwise or counterclockwise direction as needed, so that the material has a rotational force when in suspension, so that the material does not stick to the inner wall of the reaction chamber 2.

[0015] After the material is discharged through the discharge port 6, the internal wind cap 9 can be opened, and the gas enters the gas distribution cylinder 7 through the air inlet pipe 8. The gas distribution cylinder 7 uniformly enters the internal wind cap 9, and the gas outlet direction in the gas cap 9 is consistent. When the gas is introduced, the gas inside the reaction chamber 2 can form a cyclone. The gas moves in one direction, and the flow air chamber 4 provides upward gas, and the material performs a suspended, rotating and rising movement inside the reaction chamber 2. In this way, even if the external temperature is too high and reaches the sintering point, the sintered material will be brought down under the movement of the material to prevent sintering. At the same time, the feed chamber 1 and the reaction chamber 2 are cylindrical structures, and the top of the reaction chamber 2 is provided with a dome-shaped cap 5, which also prevents the material from sintering and sticking to the corners of the feed chamber 1 and the reaction chamber 2.
