Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chemical production, and in particular relates to a cleaning structure for an air outlet pipe of a reaction tank. Background Art
[0002] The main process principle for preparing synthetic rutile from waste acid is to remove the metallic iron in the reduced titanium ore powder by an oxidation-reduction reaction with the waste acid (dilute sulfuric acid) produced by the sulfuric acid process titanium dioxide in a reaction tank, while the titanium dioxide in the reduced titanium ore powder is enriched without reacting with the dilute sulfuric acid, thereby obtaining a high-grade synthetic rutile product.
[0003] However, the diameter of the reaction tank outlet pipe is small, and the gas flow rate is too fast, which can easily carry dust materials through the outlet pipe into the subsequent exhaust pipe and cause pipe blockage. Frequent pipe blockage brings great inconvenience to production.
[0004] Therefore, a cleaning structure for the gas outlet pipe of the reaction tank is urgently needed to solve the above problems. Utility Model Content
[0005] In view of the above-mentioned defects existing in the prior art, the utility model provides a cleaning structure for the outlet pipe of a reaction tank, comprising a dust reduction pipe and a spray mechanism, an exhaust port is provided at the top of the reaction tank, the dust reduction pipe is vertically arranged and located above the reaction tank, the bottom end of the dust reduction pipe is connected to the exhaust port of the reaction tank, the top end of the dust reduction pipe is connected to the exhaust pipe, the diameter of the dust reduction pipe is much larger than the diameter of the exhaust port of the reaction tank and at the same time much larger than the diameter of the exhaust pipe, the spray mechanism comprises a spray pipe, one end of the spray pipe is connected to the reaction tank, the other end of the spray pipe penetrates into the dust reduction pipe and is provided with a nozzle assembly for spraying, and the spray pipe and the dust reduction pipe are sealed.
[0006] Optionally, the nozzle assembly includes an outer annular pipe and an inner annular pipe, and the outer annular pipe is arranged outside the inner annular pipe, both the outer annular pipe and the inner annular pipe are connected to the spray pipe, and multiple nozzles are evenly distributed at the bottom of the outer annular pipe and the inner annular pipe.
[0007] Specifically, the advantage of such a design is that the spraying area is increased, so that the waste acid can fully contact with the dust material, thereby achieving a good dust reduction purpose.
[0008] Optionally, a first valve is provided at the exhaust port of the reaction tank.
[0009] Optionally, the diameter of the dust reduction duct is 1-1.5 m.
[0010] Optionally, an exhaust fan is provided on the exhaust duct.
[0011] Optionally, a second valve, a liquid extraction pump and a booster pump are provided on the spray pipeline.
[0012] Specifically, the second valve is a corrosion-resistant valve, and the liquid pump and the booster pump are both corrosion-resistant pumps.
[0013] The utility model also includes other components that can make the cleaning structure of a reaction tank outlet pipe normally used, which are all conventional technical means in this field. In addition, the devices or components not limited in the utility model all adopt conventional technical means in this field.
[0014] The working principle of the utility model is that when in use, the first valve is opened, and the gas generated in the reaction tank enters the dust reduction pipe. Since the diameter of the dust reduction pipe is large, the flow rate of the gas is reduced when passing through, and the dust falls under the action of gravity, thereby achieving the effect of gas-solid separation. At the same time, the second valve, the liquid pump and the booster pump are opened to draw part of the waste acid in the reaction tank into the spray pipe and spray it out through the nozzle, so as to carry out dust reduction treatment on the gas in the dust reduction pipe, further separate the dust substances, and reduce the occurrence of subsequent exhaust pipe blockage.
[0015] The beneficial effect of the utility model is that part of the original vertical exhaust pipe is replaced with a dust reduction pipe with a larger diameter, so that the flow rate of the gas is slowed down when passing through, thereby achieving the purpose of separating the dust. At the same time, a waste acid spray pipe is added to further separate the dust substances in the gas and reduce the occurrence of subsequent exhaust pipe blockage. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is described in detail below in conjunction with the drawings and specific embodiments in the embodiments of the present invention. The description here is only used to explain the present invention, but not to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work, any modifications, equivalent replacements, improvements, etc., should be included in the protection scope of the present invention.
[0022] Example
[0023] like Figure 1-3 As shown, an embodiment of the utility model provides a cleaning structure for an outlet pipe of a reaction tank, including a dust reduction pipe 2 and a spray mechanism. An exhaust port 4 is provided at the top of the reaction tank 1, and a first valve 5 is provided at the exhaust port 4. The dust reduction pipe 2 is vertically arranged and located above the reaction tank 1. The bottom end of the dust reduction pipe 2 is connected to the exhaust port 4 of the reaction tank 1, and the top end of the dust reduction pipe 2 is connected to the exhaust pipe 3. The diameter of the dust reduction pipe 2 is 1.5m, and the diameter of the dust reduction pipe 2 is much larger than the diameter of the exhaust port 4 of the reaction tank 1 and much larger than the diameter of the exhaust pipe 3. The spray mechanism includes a spray pipe 6, one end of the spray pipe 6 is connected to the reaction tank 1, and the other end of the spray pipe 6 penetrates into the dust reduction pipe 2 and is provided with a nozzle assembly 7 for spraying, and the spray pipe 6 and the dust reduction pipe 2 are sealed. Connection.
[0024] The nozzle assembly 7 includes an outer annular pipe 8 and an inner annular pipe 9, and the outer annular pipe 8 is arranged outside the inner annular pipe 9. The outer annular pipe 8 and the inner annular pipe 9 are both connected to the spray pipe 6, and a plurality of nozzles 10 are evenly distributed at the bottom of the outer annular pipe 8 and the inner annular pipe 9. The advantage of such a design is that the spraying area is increased, so that the waste acid can fully contact the dust material, thereby achieving a good dust reduction purpose.
[0025] In addition, an exhaust fan (not shown) is provided on the exhaust pipe 3. A second valve 11, a liquid extraction pump 12 and a booster pump 13 are provided on the spray pipe 6, and the second valve 11 is a corrosion-resistant valve, and the liquid extraction pump 12 and the booster pump 13 are both corrosion-resistant pumps.
[0026] The working principle of the utility model is that, when in use, the first valve 5 is opened, and the gas generated by the reaction tank 1 enters the dust reduction pipe 2. Since the diameter of the dust reduction pipe 2 is relatively large, the flow rate of the gas is reduced when passing through, and the dust falls under the action of gravity, thereby achieving the effect of gas-solid separation. At the same time, the second valve 11, the liquid pump 12 and the booster pump 13 are opened to draw part of the waste acid in the reaction tank 1 into the spray pipe 6 and spray it out through the nozzle 10, so as to perform dust reduction treatment on the gas in the dust reduction pipe 2, further separate the dust substances, and reduce the occurrence of subsequent exhaust pipe blockage.
[0027] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.
