Description

Technical Field

[0001] This utility model relates to the field of circulating cooler technology, and in particular to an isobutyric acid circulating cooler. Background Technology

[0002] Isobutyric acid circulating coolers have a wide range of applications, including metallurgy, chemical industry, energy, transportation, light industry, food and other industrial sectors, and are suitable for different working conditions such as cooling, condensation, heating, evaporation and waste heat recovery.

[0003] Chinese patent CN223332210U discloses a gravity-powered isobutyric acid circulating cooler. This gravity-powered isobutyric acid circulating cooler, when in use, uses condenser tubes in a cooling tank to evenly distribute air from bottom to top within the gas-liquid oxidation reactor, reducing material density. One end of the cooling tank, lacking gas, has a higher density. Under the action of the cooling tank, a gravity difference drives material circulation within the gas-liquid oxidation reactor. The heat generated by the reaction is rapidly removed by the refrigerant in multiple condenser tubes, rapidly increasing reaction efficiency. This stabilizes the gas-liquid oxidation reactor, facilitating automated design and stable operation, allowing isobutyraldehyde to rapidly generate isobutyric acid under stable conditions. Furthermore, the rotating rod and blades drive the cooling water in the cooling tank to flow rapidly, improving cooling effect. However, while solving these problems, this gravity-powered isobutyric acid circulating cooler has the following drawbacks:

[0004] By relying on the density difference of the materials in the cooling tank and the gas-liquid oxidation reactor, the materials circulate in the cooling tank and the gas-liquid oxidation reactor by gravity to achieve the purpose of heat dissipation and cooling. However, since there is no power source, the circulation rate of the materials is slow, which affects the cooling efficiency of the materials. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this invention is to provide an isobutyric acid circulating cooler, which aims to solve the problem that the material circulation rate in existing gravity-powered isobutyric acid circulating coolers is slow, thus affecting the material cooling efficiency.

[0007] To achieve the above objectives, one embodiment of this utility model provides an isobutyric acid circulating cooler, including a tank body. The bottom of the tank body is provided with a liquid inlet pipe for injecting liquid raw materials into the tank body. The bottom of the outer surface of the tank body is provided with an air inlet pipe, and one end of the air inlet pipe that penetrates into the tank body is fixedly connected to a dispersion plate. The top of the dispersion plate is provided with multiple air outlet holes. The tank body is provided with a spiral cooling pipe. The top end of the spiral cooling pipe is welded and fixed with a water inlet pipe, and the bottom end of the spiral cooling pipe is welded and fixed with a drain pipe. Both the water inlet pipe and the drain pipe penetrate to the outside of the tank body.

[0008] The beneficial effects are as follows: by installing a spiral cooling pipe inside the tank, the coolant can be directly transported to the spiral cooling pipe through the water inlet pipe, thereby exchanging heat with the raw materials undergoing oxidation reaction inside the tank. After heat exchange, the coolant is discharged from the drain pipe and recycled after cooling. This method eliminates the need for material circulation inside the tank, and can quickly cool all the raw materials inside the tank.

[0009] Furthermore, the top of the tank is provided with an exhaust pipe, and the top of the outer surface of the tank is provided with a liquid outlet pipe.

[0010] Furthermore, multiple supports are welded and fixed to the outer surface of the tank for mounting the tank within a steel structure building that supports the device.

[0011] In a preferred embodiment, the tank body includes a tank body and a tank lid. A connecting ring 1 is welded and fixed to the top edge of the tank body, and the connecting ring 1 has multiple through holes 1. A connecting ring 2 is welded and fixed to the bottom edge of the tank lid, and the connecting ring 2 has multiple through holes 2. A bolt 1 passes through the through holes 1 and through holes 2, and then a nut is threaded onto the bolt, so that the tank lid can be detachably installed on the top of the tank body. Thus, when cleaning the inner wall of the tank later, the tank lid can be lifted, and then the inner wall of the tank body can be cleaned.

[0012] Furthermore, a three-way valve is fixedly installed at the bottom of the inlet pipe. One end of the three-way valve is connected to a liquid delivery pipe for delivering liquid raw materials to the inside of the tank, while the other end of the three-way valve is used to discharge cleaning fluid. When cleaning the inside of the tank, the cleaning fluid can be discharged from one end of the three-way valve by adjusting the three-way valve.

[0013] The beneficial effects are as follows: by setting a detachable tank lid, it is convenient to open the top of the tank later to enter the tank for cleaning. In addition, the three-way valve at the liquid inlet pipe can directly discharge the cleaning liquid without passing through the liquid raw material conveying pipeline, thus avoiding the problem of the conveying pipeline being contaminated.

[0014] In a preferred embodiment, the bottom of the dispersion plate is provided with a funnel, and the lowest end of the funnel is provided with a drain port. When cleaning the tank, if the cleaning liquid enters the dispersion plate through the vent, the cleaning liquid in the dispersion plate will flow through the inclined side wall of the funnel to the drain port and then be discharged.

[0015] The beneficial effects are as follows: when cleaning the tank, if the cleaning fluid enters the dispersion plate through the vent, the cleaning fluid will flow down from the side wall of the funnel and then be discharged from the drain port, thus avoiding the problem of residual cleaning fluid in the dispersion plate, which could lead to the problem of cleaning fluid contaminating the raw materials during later use.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0027] This invention provides an isobutyric acid circulating cooler.

[0028] Example 1:

[0029] like Figure 1-2 As shown, it includes a tank body 1. The bottom of the tank body 1 is provided with a liquid inlet pipe 11 for injecting liquid raw materials into the tank body 1, so that the liquid raw materials gradually rise in the tank body 1. The bottom of the outer surface of the tank body 1 is provided with an air inlet pipe 12, and one end of the air inlet pipe 12 that extends into the tank body 1 is fixedly connected to a dispersion plate 2. The top of the dispersion plate 2 is provided with multiple air outlet holes 21. Oxidizing gas enters the dispersion plate 2 through the air inlet pipe 12, and then flows through several air outlet holes 21 to be evenly dispersed into the liquid in the tank body 1. The top of the tank body 1 is provided with an exhaust pipe 13, and the top of the outer surface of the tank body 1 is provided with a liquid outlet pipe 14. Multiple supports 15 are welded and fixed to the outer surface of the tank body 1 for mounting the tank body 1 in a steel structure building that supports the device.

[0030] The tank body 1 is equipped with a spiral cooling pipe 3. Multiple support rods are welded and fixed to the inner wall of the tank body 1. The ends of the support rods are welded and fixed to the spiral cooling pipe 3, or pipe clamps are set at the ends of the support rods and fixed to the surface of the spiral cooling pipe 3, thereby fixing the spiral cooling pipe 3 inside the tank body 1. A water inlet pipe 31 is welded and fixed to the top of the spiral cooling pipe 3, and a drain pipe 32 is welded and fixed to the bottom of the spiral cooling pipe 3. Both the water inlet pipe 31 and the drain pipe 32 extend to the outside of the tank body 1. The joints between the water inlet pipe 31 and the drain pipe 32 and the tank body 1 are sealed by welding.

[0031] The working principle of this embodiment is as follows: When in use, after the raw materials such as isobutyraldehyde and catalyst are prepared, they are injected into the tank 1 through the liquid inlet pipe 11. Then, oxygen is sent into the dispersion plate 2 through the air inlet pipe 12. The oxygen enters the tank 1 through several air outlets 21, mixes with the raw materials, and undergoes an oxidation reaction. The coolant is pumped to the water inlet pipe 31 by a water pump, and then enters the spiral cooling pipe 3. Since the spiral cooling pipe 3 is located inside the raw materials in the tank 1, it exchanges heat with the raw materials in the tank 1. The coolant after heat exchange is discharged through the drain pipe 32 for cooling and then recycled.

[0032] Example 2:

[0033] like Figure 3-6 As shown, based on Embodiment 1, the tank 1 includes a tank body 4 and a tank cover 5. A connecting ring 41 is welded and fixed to the top edge of the tank body 4, and multiple through holes 42 are provided on the connecting ring 41. A connecting ring 51 is welded and fixed to the bottom edge of the tank cover 5, and multiple through holes 52 are provided on the connecting ring 51. A bolt is used to pass through the through holes 41 and 52, and then a nut is threaded onto the bolt. The tank cover 5 can be detachably installed on the top of the tank body 4. Thus, when cleaning the inner wall of the tank body 1 later, the tank cover 5 can be lifted up and the inner wall of the tank body 1 can be cleaned.

[0034] Furthermore, a three-way valve 16 is fixedly installed at the bottom of the liquid inlet pipe 11. One end of the three-way valve 16 is connected to the liquid conveying pipeline for conveying liquid raw materials to the inside of the tank 1. The other end of the three-way valve 16 is used to discharge cleaning fluid. When cleaning the inside of the tank 1, the cleaning fluid can be discharged from one end of the three-way valve 16 by adjusting the three-way valve, so as to prevent the cleaning fluid from entering the liquid raw material conveying pipeline and remaining in the pipeline, which would cause the cleaning fluid to contaminate the liquid raw materials when conveying them later.

[0035] Preferably, the bottom of the dispersion plate 2 is provided with a funnel 22, and the lowest end of the funnel 22 is provided with a drain port 23. When cleaning the tank 1, if the cleaning liquid enters the dispersion plate 2 through the vent 21, the cleaning liquid in the dispersion plate 2 will flow through the inclined side wall of the funnel 22 to the drain port 23 and then be discharged, thus avoiding the problem of residual cleaning liquid in the dispersion plate 2, which would cause the cleaning liquid to contaminate the liquid raw materials during later use.
