Description

Technical Field

[0001] The utility model relates to the technical field of chemical synthesis, in particular to a reaction kettle with a waste heat recovery function. Background Art

[0002] Chemical synthesis, also known as synthetic chemistry, is the foundation and core of organic chemistry, inorganic chemistry, medicinal chemistry, polymer chemistry, materials chemistry and other disciplines. It includes esterification reactions, oxidation reactions and reduction reactions, etc. Chemical synthesis is usually carried out in a reactor.

[0003] Most chemical synthesis reactions will produce a large amount of gas. Direct discharge of this gas will seriously pollute the environment, so factories need to purify this gas. However, when the esterification reaction and oxidation reaction in chemical synthesis are in progress, a large amount of heat is released at the same time as the gas, so that the gas itself contains a large amount of heat. When this gas is directly purified, it will undoubtedly cause additional waste, which does not meet the energy-saving requirements of most factories today. Therefore, the utility model is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1In this embodiment, a reactor with waste heat recovery function includes a base 1, a reactor 2 is fixedly installed on the upper surface of the base 1, a feed pipe 3 is connected to the top of the reactor 2, a discharge pipe 4 extending to the bottom of the base 1 is connected to the bottom of the reactor 2, a stirring component is arranged inside the reactor 2, a recovery box 5 is arranged on the upper surface of the base 1 and located on one side of the reactor 2, and a recovery component is arranged inside the recovery box 5.

[0021] Example 1: Please refer to Figure 1 and Figure 2 In this embodiment, the recovery component includes a bellows 6 fixedly mounted on the top of the recovery box 5, a conveying member is arranged inside the bellows 6, and a waste heat recovery member is arranged inside the recovery box 5.

[0022] Among them, the waste heat recovery component includes a spiral tube 8 fixedly installed inside the recovery box 5, one end of the spiral tube 8 extends to the outside of the recovery box 5, and the other end of the spiral tube 8 extends to the top of the recovery box 5 and is connected to the inside of the bellows 6. A water pump 9 is arranged on the upper surface of the base 1, and water pipes are fixedly installed at the output and input ends of the water pump 9. The other ends of the water pipes at the output and input ends of the water pump 9 are connected to the inside of the recovery box 5. The water pipe at the output end of the water pump 9 is located above the water pipe at the input end of the water pump 9. A first temperature sensor 10 is fixedly installed on the inner wall of one side of the recovery box 5.

[0023] It should be noted that when the gas passes through the spiral tube 8, the water source inside the recovery box 5 will absorb the heat in the gas, thereby recovering the heat in the gas. By starting the water pump 9 to drive the water source to flow, the water source inside the recovery box 5 will not be in a static state, thereby accelerating the absorption efficiency of the water source and further improving the recovery efficiency. The water temperature is monitored in real time by the first temperature sensor 10. When the water temperature reaches the limit value, the water source is discharged through the water outlet pipe 12 and discharged into the new water source through the water inlet pipe 11.

[0024] It is understandable that the surface of the spiral tube 8 located outside the recovery box 5 is fixedly sleeved with a heat insulating sleeve 13. By providing the heat insulating sleeve 13, it is convenient to insulate the spiral tube 8 outside, which is convenient for the heat loss in the gas, thereby causing unnecessary waste.

[0025] Secondly, a water inlet pipe 11 is connected to one side surface of the recovery box 5 , and a water outlet pipe 12 extending to the bottom of the base 1 is connected to the bottom of the recovery box 5 . Valves are fixedly installed on the water inlet pipe 11 and the water outlet pipe 12 .

[0026] See also Figure 1 and Figure 2In this embodiment, the conveying member includes a fan 14 fixedly mounted on the inner bottom wall of the bellows 6, the output end of the fan 14 faces the spiral tube 8, the top of the bellows 6 is connected to an air supply pipe 15, and the other end of the air supply pipe 15 is connected to the interior of the reactor 2.

[0027] By providing the fan 14 , it is convenient to input the gas entering the wind box 6 into the spiral tube 8 .

[0028] Among them, the side surface of the bellows 6 away from the spiral tube 8 is an open structure and a sealing cover is hinged on the inner wall. A filter screen 16 is fixedly installed on the inner wall of the bellows 6 and located between the fan 14 and the air supply pipe 15. A second temperature sensor 17 is fixedly installed on the inner wall of the bellows 6 and located on the left side of the filter screen 16.

[0029] By setting up a filter 16, impurities in the gas are blocked to prevent the impurities from affecting the normal operation of the fan 14. By setting up a second temperature sensor 17, the temperature inside the bellows 6 is detected. When the second temperature sensor 17 detects a change in the temperature inside the bellows 6, it means that the gas generated in the reactor 2 has entered the bellows 6.

[0030] Example 2: Please refer to Figure 1 and Figure 3 In this embodiment, the stirring assembly includes a sealing box 18 fixedly installed on the inner wall of the reactor 2, a protective box fixedly installed on the top of the reactor 2, a motor 19 fixedly installed on the inner wall of the protective box, a first rotating shaft 20 extending to the inside of the sealing box 18 is fixedly installed on the output end of the motor 19, a second rotating shaft 21 is rotatably installed on the inner top wall of the sealing box 18 and located on the left side of the first rotating shaft 20, the other ends of the first rotating shaft 20 and the second rotating shaft 21 are vertically movable through the sealing box 18 through bearings and are rotatably connected to the inner bottom wall of the reactor 2, stirring rods 22 are fixedly installed on the surfaces of the first rotating shaft 20 and the second rotating shaft 21, a driving gear 23 is fixedly sleeved on the surface of the first rotating shaft 20 and located inside the sealing box 18, and a driven gear 7 is fixedly sleeved on the surface of the second rotating shaft 21, and the driven gear 7 and the driving gear 23 are meshed with each other.

[0031] The starting motor 19 drives the first rotating shaft 20 to rotate, thereby driving the driven gear 7 to rotate through the driving gear 23, and then driving the second rotating shaft 21 to rotate, and the first rotating shaft 20 and the second rotating shaft 21 rotate in opposite directions, thereby allowing the materials in the reactor 2 to collide and mix, greatly saving the time required for the reaction and improving the stirring efficiency.

[0032] The working principle of the above embodiment is as follows: when the second temperature sensor 17 detects that the temperature inside the bellows 6 changes, the gas generated in the reactor 2 has entered the bellows 6. At this time, the fan 14 is started to input the gas entering the bellows 6 into the spiral tube 8. When the gas passes through the spiral tube 8, the water source inside the recovery box 5 absorbs the heat in the gas, thereby recovering the heat in the gas. By starting the water pump 9 to drive the water source to flow, the water source will not be in a static state inside the recovery box 5, thereby accelerating the absorption efficiency of the water source and further improving the recovery efficiency. The water temperature is monitored in real time by the first temperature sensor 10. When the water temperature reaches the limit value, the water source is discharged from the water outlet pipe 12 and discharged into the new water source through the water inlet pipe 11. Through the above operation, the device can recover the heat in the gas, thereby meeting the energy-saving requirements of most factories today.

[0033] The electrical components appearing in the article are all electrically connected to the main controller and the power supply.
