Abstract
Description
Technical Field
[0001] The utility model relates to the field of storage equipment, in particular to an intelligent storage tank for MTBE production. Background Technique
[0002] MTBE has a good blending effect in gasoline components. As a gasoline additive, it has very good anti-explosion performance and good chemical stability. Gasoline added with MTBE can also improve the driving performance of automobiles, increase the oxygen in gasoline, and reduce the content of carbon monoxide in exhaust gas. However, the toxicity and danger of MTBE should also be fully emphasized during storage and use. In the prior art, for the storage of MTBE, a special storage area generally needs to be set up. Therefore, the storage tanks in highly concentrated areas often have problems of uneven ventilation and heat dissipation. MTBE is prone to volatilization due to excessive temperature, and at the same time, the pressure of the storage tank increases, posing an explosion risk. Considering the flammability of MTBE, a cofferdam also needs to be set up to prevent the spread of fire after leakage. However, in the existing special area for storing MTBE, a unified cofferdam is set up, resulting in poor fire prevention and leakage prevention effects. But if there are multiple storage tanks and multiple cofferdams are set up, it will consume a large amount of manpower and material resources, increase the construction difficulty, and increase the production cost of the enterprise. Content of the Utility Model

Specific embodiments
[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0020] Embodiment
[0021] In this embodiment, an intelligent storage tank for MTBE production, as Figures 1-5 shown, includes a base 1 and a storage tank body 2.
[0022] In this embodiment, the base 1 is welded with the storage tank body 2; the storage tank body 2 is connected with a connecting pipe 4; a plurality of equally spaced communication holes 4001 are opened on the side wall of the connecting pipe 4; the upper part of the connecting pipe 4 is communicated with a first conduit 5; the outer ring surface of the connecting pipe 4 is rotatably connected with a rotating cylinder 6; an annular cavity is formed between the connecting pipe 4 and the rotating cylinder 6, and all the communication holes 4001 are located in the annular cavity; the rotating cylinder 6 is communicated with a plurality of equally spaced second conduits 7; each second conduit 7 is provided with a nozzle 7001. Since MTBE is flammable at high temperatures and forms an explosive mixture with air, special attention should be paid to its storage conditions in the hot summer. First, the storage tank body 2 is installed in the base 1 in a cool and ventilated warehouse, and MTBE is injected into the storage tank body 2 for storage. Then, the staff connects the first conduit 5 with an external cooling water pipeline. When the temperature detector detects that the temperature of the storage tank body 2 is higher than 37°C, the cooling water enters the connecting pipe 4 through the first conduit 5. Since a plurality of communication holes 4001 are opened on the connecting pipe 4, the cooling water enters the rotating cylinder 6 through each communication hole 4001, and then the cooling water flows to each second conduit 7 through the rotating cylinder 6. Then, the cooling water is sprayed out to the surface of the storage tank body 2 through each nozzle 7001, realizing the spray cooling of the storage tank body 2 and avoiding the too high temperature of the storage tank body 2.
[0023] In this embodiment, a foam concentrate cylinder 3 is fixedly connected to the upper part of the storage tank body 2; the upper part of the foam concentrate cylinder 3 is connected to the connecting pipe 4; two electromagnetic valves 4002 symmetrically distributed up and down are arranged in the connecting pipe 4. Considering that the corrosion of the storage tank body 2 may cause leakage, and the leakage rate of MTBE is high, a large amount of MTBE will leak in a short time, accompanied by the associated / secondary pollution of various volatile organic gases. Therefore, the staff needs to regularly check the storage tank body 2 to ensure the integrity of each safety accessory, and monitor the leakage of MTBE in real time through the combustible gas detector deployed in the warehouse where the storage tank body 2 is located. When leakage occurs, MTBE seeps to the surface of the storage tank body 2, and a small amount of MTBE vaporizes. After MTBE vaporizes, it becomes a combustible gas. Then the combustible gas detector in the warehouse detects the vaporized MTBE, that is, It is clear that MTBE has leaked. At this time, the two solenoid valves 4002 in the connecting pipe 4 are controlled to open, and the cooling water in the first conduit 5 enters the foam liquid cartridge 3 through the connecting pipe 4, so that the foam liquid in the foam liquid cartridge 3 is mixed with water. At this time, the solenoid valve 4002 above the connecting pipe 4 is closed. After the foam liquid reacts with water for a period of time, the foam liquid in the foam liquid cartridge 3 produces a large amount of foam in a short time. The foam passes through the solenoid valve 4002 below the connecting pipe 4 and enters the connecting pipe 4, and then flows to each second conduit 7 through the rotating drum 6, and then sprays the foam to the surface of the storage tank body 2 through the nozzle 7001. The foam covers the surface of the storage tank body 2, and also covers the MTBE leaked to the surface of the storage tank body 2, to prevent the leaked MTBE from continuing to vaporize, thereby preventing MTBE from catching fire.
[0024] In this embodiment, the nozzle 7001 is tilted and opened on the second conduit 7 toward the side close to the storage tank body 2; the rotating drum 6 is connected with a plurality of equally distributed second conduits 7; each second conduit 7 has a nozzle 7001; the base 1 is installed with a first annular guide rail 8; a plurality of equally distributed first sliders 9 are slidably connected to the first annular guide rail 8; each first slider 9 is fixedly connected to a second conduit 7; a second annular guide rail 10 is installed on the upper part of the storage tank body 2; a plurality of equally distributed second sliders 11 are slidably connected to the second annular guide rail 10; each second slider 11 is fixedly connected to a second conduit 7. When cooling water is sprayed out through the nozzle 7001, the nozzle 7001 is not directly facing the storage tank body 2, but sprayed out at an inclined angle. Therefore, the reverse thrust of the water spray provides a rotation thrust for the second conduit 7. Under the cooperation of the first annular guide rail 8, the first slider 9, the second annular guide rail 10 and the second slider 11, all the second conduits 7 jointly drive the rotating drum 6 to rotate on the connecting pipe 4. Through the rotation of the second conduit 7, as shown in Figure 5As shown, it is realized to evenly spray the cooling water onto the surface of the storage tank body 2 to evenly cool the storage tank body 2. When foam surges into the second conduit 7, a large amount of foam sprays out from the nozzle 7001, applying a reaction force to the second conduit 7 and causing the second conduit 7 to rotate. The sprayed foam is similar to the foam sprayed from a fire extinguisher. As the second conduit 7 rotates, the nozzle 7001 also evenly sprays the foam onto the surface of the storage tank body 2 to achieve full coverage of the surface of the storage tank body 2 and prevent a fire from occurring to MTBE.
[0025] In this embodiment, the storage tank body 2 includes a material guiding pipe 2001, a feeding pipe 2002, and a floating roof 2003; the storage tank body 2 is connected to the material guiding pipe 2001; several openings are formed in the lower part of the material guiding pipe 2001, and all the openings are communicated with the inside of the storage tank body 2; the upper part of the material guiding pipe 2001 is communicated with the feeding pipe 2002; the feeding pipe 2002 is located outside the storage tank body 2; a floating roof 2003 is slidably connected inside the storage tank body 2; the floating roof 2003 is slidably connected to the material guiding pipe 2001. To reduce the volatilization of volatile organic gases, a floating roof 2003 is arranged inside the storage tank body 2. When MTBE is injected into the material guiding pipe 2001 through the feeding pipe 2002, the material guiding pipe 2001 enters the storage tank body 2 through the openings in its lower part. At this time, the floating roof 2003 is located on the liquid surface of MTBE. As the injected MTBE increases, the floating roof 2003 is gradually lifted. Since the floating roof 2003 floats on the liquid surface of MTBE, there is no evaporation space for MTBE, which can reduce the evaporation loss of MTBE. And the floating roof 2003 blocks the air from MTBE, avoiding the mixture of MTBE and air to form an explosive mixture, preventing the occurrence of fire and explosion hazards, and reducing air pollution. A material taking pipe is arranged at the lower part of the storage tank body 2, so that the MTBE in the storage tank body 2 can be conveniently taken.
[0026] In this embodiment, an annular groove 8001 is formed between the first annular guide rail 8 and the storage tank body 2; an alcohol-resistant foam material is arranged in the annular groove 8001 between the first annular guide rail 8 and the storage tank body 2. The annular groove 8001 can collect the water flowing down along the outer wall of the storage tank body 2 when spraying and cooling the storage tank body 2, and then the water can be recycled after being filtered. When spraying foam on the storage tank body 2, the annular groove 8001 can block the leakage of MTBE, absorb MTBE through the alcohol-resistant foam material, avoid the volatilization of MTBE exposed to the air, and collect the foam flowing down along the outer wall of the storage tank body 2 to prevent the foam from contaminating the ground with MTBE, providing convenience for subsequent treatment of the leaked MTBE and foam.
[0027] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily conceive of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
