Technical Field
[0001] This utility model relates to the field of trimethylamine wastewater recovery technology, and in particular to a trimethylamine recovery device. Background Technology
[0002] Trimethylamine (TMA) is the simplest tertiary amine. It is a colorless gas at room temperature with a fishy, foul odor. It is soluble in water, ethanol, and ether. It is flammable and toxic. Its saturated aqueous solution has a relative density of 0.66, while the relative density of air is 2.09. Its molecular formula is C3H9N. It can be used as an analytical reagent and in organic synthesis for amination. Its main uses include pharmaceuticals, pesticides, dyes, and other organic synthesis raw materials, as well as in the synthesis of cationic etherifying agents. In pharmaceuticals, it acts as an emulsifier, solubilizer, dispersant, and wetting agent, and in synthesis, it is used as a flotation agent.
[0003] The treatment of trimethylamine wastewater involves the use of a reaction vessel. Liquid alkali is added to the reaction vessel to react and recover the trimethylamine wastewater. To ensure a complete reaction between the liquid alkali and the trimethylamine wastewater, the reaction vessel is usually equipped with a stirring component. However, existing trimethylamine recovery devices do not have a filtration function when the wastewater enters the reaction vessel. This can easily cause the ribbon-like impurities in the wastewater to become entangled in the stirring component inside the reaction vessel, leading to the reaction vessel malfunctioning.

[0025] Example 1, as Figure 1-6 As shown, a trimethylamine recovery device includes a reaction vessel body 1. Two support rods 7 are fixedly installed on one side surface of the reaction vessel body 1, and a filter box 8 is fitted on the side surface away from the reaction vessel body 1. A water inlet pipe 9 is fixedly installed on one side surface of the filter box 8. A discharge pipe 10 connects the filter box 8 and the reaction vessel body 1. Filter devices 3 for filtering wastewater are provided on both inner walls of the filter box 8.
[0026] Reference Figure 2-6As shown, in this embodiment: the filter device 3 includes vertical grooves 31 formed on the inner wall surfaces of both sides of the filter box 8, and a filter screen 32 is slidably inserted between the two vertical grooves 31. The filter device 3 also includes a sliding groove 33 formed on the top surface of the filter screen 32 and a sliding plate 34 inside it. A limiting rod 35 is fixedly installed on the surface of the sliding plate 34. A limiting hole 36 is formed on the inner wall surface of one side of one of the vertical grooves 31. The filter device 3 also includes a support plate 37 fixedly installed on the top surface of the filter screen 32. A spring 38 is fixedly installed between the support plate 37 and the sliding plate 34, so that the filter screen 32 can be installed inside the filter box 8. Thus, the filter screen 32 can filter out the ribbon-like impurities inside the wastewater before it enters the reactor body 1, avoiding damage to the stirring assembly 12.
[0027] Reference Figure 1-3 As shown in this embodiment: the bottom surface of the reactor body 1 is provided with a feed pipe 4 and a solenoid valve 5 for controlling its opening and closing is installed on its outer wall surface. Multiple support legs 6 are distributed in a ring on the outer wall surface of the reactor body 1. A feed pipe 14 is fixedly installed on the outer wall surface of the reactor body 1. The top surface of the reactor body 1 is covered with a lid 11. The surface of the lid 11 is provided with a stirring assembly 12 and two handles 13. The stirring assembly 12 is used to stir the wastewater and liquid alkali inside the reactor body 1.
[0028] Reference Figure 1-4 As shown in this embodiment: Both sides of the outer wall surface of the vessel lid 11 are provided with fixing devices 2 for fixing the vessel lid 11 and the reactor body 1 together. The fixing devices 2 include limiting plates 201 fixedly installed on both sides of the vessel lid 11, and limiting frames 202 fixedly installed on both sides of the outer wall surface of the reactor body 1. The surface of the limiting plate 201 has a strip groove 203 and a sliding moving plate 204 inside it. Two positioning rods 205 are fixedly installed on the surface of the moving plate 204. The limiting frame... Two positioning holes 206 are opened on one side of the inner wall surface of 202. The fixing device 2 also includes an L-shaped plate 207 fixedly installed on the surface of the limiting plate 201. The inner wall surface of the L-shaped plate 207 is provided with a long groove 208 and a T-shaped plate 209 that slides inside it. The T-shaped plate 209 and the moving plate 204 are hinged by a hinge plate 210. An electric telescopic rod 211 is fixedly installed on the top surface of the L-shaped plate 207. The electric telescopic rod 211 drives the T-shaped plate 209 to move inside the long groove 208.
[0029] Working principle: When using this device, first connect the feed pipe 14 to the inlet of the external distillation column. After connection, slide the slide plate 34, allowing it to move inside the trough 33. This movement compresses the spring 38, and simultaneously moves the limiting rod 35. When the limiting rod 35 reaches the appropriate position, slide the filter screen 32 between the two vertical slots 31. After the filter screen 32 and vertical slots 31 are connected, release the slide plate 34. The spring 38's rebound force resets the limiting rod 35, allowing it to insert itself into the limiting hole 36. The filter screen 32 is installed inside the filter box 8 by inserting it into the hole 36. Then, trimethylamine wastewater is introduced into the filter box 8 through the inlet pipe 9, and then transported into the reactor body 1 through the outlet pipe 10. When the wastewater enters the reactor body 1 from the outlet pipe 10, it is filtered by the filter screen 32, which removes ribbon-like impurities from the wastewater, preventing them from entering the reactor body 1. When the reactor is filled with an appropriate amount of wastewater, liquid alkali is added into the reactor body 1 through the feed pipe 14, and the stirring assembly 12 is turned on to accelerate the mixing reaction of the wastewater and liquid alkali. Through the combination of the above structures, the filter screen 32 can be installed inside the filter box 8, thereby utilizing the filter... Net 32 can filter out ribbon-like impurities inside the wastewater before it enters the reactor body 1, preventing damage to the stirring component 12. Simultaneously, after the trimethylamine wastewater and liquid alkali have fully reacted, the solenoid valve 5 is opened, allowing the generated trimethylamine gas to enter the distillation column for distillation. Combined with external cooling, this completes the final recovery process. When the reactor body 1 is no longer in use and needs cleaning, the electric telescopic rod 211 is activated first. The activation of the electric telescopic rod 211 moves the T-shaped plate 209 inside the long trough 208. The movement of the T-shaped plate 209 in the long trough 208 pulls the moving plate 204 inside the strip trough 203. 204 moves inside the strip groove 203, causing the positioning rod 205 to move. The positioning rod 205 moves and moves out of the positioning hole 206. The separation of the positioning rod 205 and the positioning hole 206 causes the limiting plate 201 to lose its limiting position inside the limiting frame 202. The limiting plate 201 and the limiting frame 202 lose their limiting position, causing the lid 11 and the reactor body 1 to lose their limiting position. At this time, both hands pull the handle 13. The handle 13 moves and causes the lid 11 to move. The lid 11 moves and causes the limiting plate 201 to move out of the limiting frame 202. At the same time, the lid 11 moves and moves away from the top surface of the reactor. At this time, the lid 11 is no longer obstructing the reactor, which makes it easier to clean the inside of the reactor and facilitates the next use.
