[0017] Compared with the prior art, the present application has the following advantages:

[0018] The efficient vaporization equipment of the TMA recovery device stores the waste water in the water-absorbing carrier, and the water-absorbing carrier is heated by the heating carrier. Since the boiling point of trimethylamine is much lower than that of water, the trimethylamine is vaporized into a gaseous state by heating the waste water, while the water and other high-boiling-point components remain in the liquid phase. Thus, the trimethylamine in the water-absorbing carrier is evaporated, thereby achieving the recovery effect of trimethylamine. After the recovery of trimethylamine is completed, the heating carrier further heats the water-absorbing carrier. At this time, under the action of high temperature, the remaining impurities in the water-absorbing carrier are crystallized, and the crystallized impurities are stored in the water-absorbing carrier. As the rotating shaft continuously drives the water-absorbing carrier and the heating carrier to rotate, the water-absorbing carrier and the heating carrier come into contact with the shaking assembly, thereby causing the carrier frame to shake up and down as a whole, and the crystallized impurities are shaken off, thereby reducing the content of impurities in the sewage at the bottom of the main cylinder and improving the recovery efficiency of trimethylamine.

[0020] Furthermore, when the rotating shaft drives the carrier frame to rotate, the carrier frame enters between the clamping plates under the guidance of the guide chute. Since the number of guide balls on different clamping plates is different, the number of clamping plates is two, one of which is arranged on the support bottom ring and the other of which is arranged at the bottom of the support top ring. The guide balls are distributed in a staggered manner. Under the limiting action of the guide balls and the elastic force of the shaking spring, the carrier frame is in an up-and-down shaking state, and the crystallized impurities are shaken and removed. Under the action of the guide spring, the elastic force of the clamping plate increases, thereby intensifying the shaking of the carrier frame and more effectively shaking and removing the crystallized impurities.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without any creative work fall within the scope of protection of the present application.

[0032] In industrial production, the commonly used vaporization recovery method is to vaporize trimethylamine by heating, so as to realize the purpose of separation and recovery from wastewater. However, in practical application, this method has a significant defect, that is, with the progress of the vaporization process, the recovery purity of trimethylamine will gradually decrease, and the recovery efficiency is not ideal. Industrial wastewater is complex, and usually contains not only trimethylamine, but also sulfides, chlorides and other impurities. The presence of these impurities is the fundamental reason for the decrease of the recovery purity of trimethylamine. Secondly, in the initial stage of vaporization recovery, since trimethylamine accounts for a relatively high proportion in wastewater, the main component of the vaporized gas is trimethylamine, and the purity of the recovered product is high at this time. However, with the continuation of the vaporization process, the content of trimethylamine in wastewater gradually decreases, while the concentration of sulfides, chlorides and other impurities relatively increases. Thirdly, when the concentration of trimethylamine in wastewater decreases to a certain extent, the composition of the gas produced by heating vaporization will change. Since part of the impurities also have a certain volatility, they will also gradually vaporize under high temperature conditions. At this time, the recovered gas will no longer contain only trimethylamine, but also contain a variety of impurities, thereby significantly reducing the recovery purity of trimethylamine. In addition, the prolongation of the vaporization process will further exacerbate this problem. With the increase of vaporization time, the concentration of impurities in wastewater will further increase, so that more impurities will vaporize, further reducing the recovery purity of trimethylamine.

[0033] As Figures 1-9 The present application provides a technical scheme: an efficient vaporization equipment for TMA recovery, comprising a main body assembly 1 and a top cover assembly 2, the main body assembly 1 comprising a main cylinder 101, the top cover assembly 2 comprising a top cover body 201, the top cover body 201 being provided with a carrier assembly 3 for absorbing wastewater and heating the wastewater, the main cylinder 101 being provided with a shaking assembly 6 for driving the carrier assembly 3 to vibrate and a storage assembly 4 for impurity recovery, and the main cylinder 101 being provided with a water spraying assembly 5 for wastewater conveying; the carrier assembly 3 comprising a carrier frame 306 and a heating carrier 307 provided on the carrier frame 306, the heating carrier 307 being provided with a water absorbing carrier 308, a rotating shaft 302 being arranged between the top cover body 201 and the main cylinder 101, the rotating shaft 302 being provided with a fixing sleeve 305, the carrier frame 306 being arranged on the fixing sleeve 305, and the top cover body 201 being provided with a driving motor 301 fixedly connected with the rotating shaft 302.

[0034] It should be noted that when the driving motor 301 starts and drives the rotating shaft 302 to rotate, the water spraying assembly 5 first transports the wastewater at the bottom of the main cylinder 101 upward and sprays it on the water absorbing carrier 308, the water absorbing carrier 308 stores the wastewater, and the heating carrier 307 heats the water absorbing carrier 308, because the boiling point of trimethylamine is much lower than that of water, so by heating the wastewater containing wastewater, trimethylamine is preferentially vaporized into a gaseous state, while water and other high-boiling components remain in a liquid phase, thereby evaporating the trimethylamine in the water absorbing carrier 308, thereby achieving the effect of recycling trimethylamine. When the trimethylamine recycling is completed, the heating carrier 307 further heats the water absorbing carrier 308, at which time under the action of high temperature, the remaining impurities in the water absorbing carrier 308 are crystallized, and the crystallized impurities are stored in the water absorbing carrier 308. As the rotating shaft 302 continuously drives the water absorbing carrier 308 and the heating carrier 307 to rotate, the water absorbing carrier 308 and the heating carrier 307 come into contact with the shaking assembly 6, thereby causing the carrier frame 306 to shake up and down as a whole, and the crystallized impurities are shaken off, thereby reducing the content of impurities in the wastewater at the bottom of the main cylinder 101, and thereby improving the recycling efficiency of trimethylamine.

[0035] As shown in Figure 2 , the main cylinder 101 is provided with a support bottom ring 103 and a support top ring 204, the support bottom ring 103 and the main cylinder 101 are provided with a first support rod 104, the support top ring 204 and the top cover body 201 are provided with a second support rod 205, and the support bottom ring 103 and the support top ring 204 are in contact with the carrier frame 306.

[0036] It should be noted that in the process of rotating and shaking the carrier frame 306 by the rotating shaft 302, the support bottom ring 103 and the support top ring 204 are used to limit the rotation of the carrier frame 306 and reset during the shaking process, that is, after the carrier frame 306 is shaken, the support bottom ring 103 and the support top ring 204 limit the carrier frame 306 again, keeping the carrier frame 306 moving normally.

[0037] As shown in Figure 3 , Figure 6 and Figure 7As shown, the shaking assembly 6 comprises a clamping plate 602 and a guide ball 603 arranged on the clamping plate 602, the support bottom ring 103 and the support top ring 204 are provided with an expansion plate 601, the expansion plate 601 is provided with a guide spring 604, the clamping plate 602 is arranged on the guide spring 604, the clamping plate 602 is provided with a guide inclined groove, the number of guide balls 603 on different clamping plates 602 is different, the fixed sleeve 305 is provided with a limiting frame 310, the limiting frame 310 is provided with a limiting rod 606, the carrier frame 306 is provided with a lifting block 309 sleeved on the limiting rod 606, the lifting block 309 is electrically connected with the fixed sleeve 305, and the lifting block 309 is provided with a shaking spring 605.

[0038] It should be noted that when the rotating shaft 302 drives the carrier frame 306 to rotate, the carrier frame 306 enters between the clamping plates 602 under the guidance of the guide inclined groove. Since the number of guide balls 603 on different clamping plates 602 is different, the number of clamping plates 602 is two, one of which is arranged on the support bottom ring 103 and the other is arranged at the bottom of the support top ring 204. The guide balls 603 are distributed in a staggered manner. Under the limiting action of the guide balls 603 and the elastic force of the shaking spring 605, the carrier frame 306 is in an up-down shaking state. The crystallized impurities are shaken and removed. Under the action of the guide spring 604, the elastic force received by the clamping plate 602 increases, thereby intensifying the shaking of the carrier frame 306 and removing the crystallized impurities with stronger effect.

[0039] As shown in Figure 9 The water absorption carrier 308 comprises a liquid receiving layer, an intermediate layer and a heat conducting layer. The liquid receiving layer is made of hydrophilic modified PAN material for quickly absorbing wastewater. The intermediate layer is made of silicon carbide nanowire reinforced ceramic cotton material for storing wastewater. The heat conducting layer is made of graphene coated aramid material for improving the heating rate.

[0040] As shown in Figure 5 The top cover body 201 is provided with a brush ring 304 and an electrical connection assembly 303. The electrical connection assembly 303 is electrically connected with the brush ring 304. The brush ring 304 is sleeved on the rotating shaft 302.

[0041] It should be noted that the electrical connection assembly 303 is used for connecting an external power source and converting voltage to deliver electric energy to the brush ring 304. When the rotating shaft 302 rotates, the brush ring 304 is used for supplying power to the fixed sleeve 305.

[0042] As shown in Figure 8 The water spraying assembly 5 comprises a flow divider 501 arranged on the top cover body 201. The flow divider 501 is electrically connected with the electrical connection assembly 303. The flow divider 501 is provided with a water suction pipe 502 and a water suction pump 503. The flow divider 501 is provided with a plurality of water spraying holes.

[0043] It should be noted that when the rotating shaft 302 drives the carrier assembly 3 to rotate to the middle position of the flow divider 501, the water suction pump 503 sucks the wastewater at the bottom of the main cylinder 101 through the water suction pipe 502 and sprays it through the water spraying hole to the water suction carrier 308 on both sides of a carrier frame 306, respectively, to uniformly spray the wastewater.

[0044] As shown in Figure 2 The top cover body 201 is provided with a first air outlet pipe 202 and a second air outlet pipe 203, and the main cylinder 101 is provided with a feeding pipe 102, through which the wastewater enters the main cylinder 101.

[0045] It should be noted that when the heating carrier 307 heats the water suction carrier 308, it is heated in a segmented manner. Since the boiling point of trimethylamine is low, it is first heated at a low temperature to evaporate the trimethylamine and recover it through the first air outlet pipe 202. After the trimethylamine is recovered, it is heated at a high temperature, which promotes the crystallization of the remaining impurities under the action of high temperature. In the process of crystallization, the gas impurities generated are discharged through the second air outlet pipe 203. The first air outlet pipe 202 is provided with a molecular sieve membrane, which is made of graphene oxide composite material with a pore size of 0.39 nm, accurately trapping macromolecules and allowing trimethylamine to pass normally. The first air outlet pipe 202 and the second air outlet pipe 203 are in an alternating working state. When low-temperature heating is performed, the first air outlet pipe 202 works and the second air outlet pipe 203 is closed. When low-temperature heating is completed, the second air outlet pipe 203 works and the first air outlet pipe 202 is closed. Therefore, the gas impurities cannot be discharged through the first air outlet pipe 202.

[0046] As shown in Figure 4 The storage assembly 4 includes a material collecting box 401, which is arranged on the supporting bottom ring 103. The material collecting box 401 is provided with a dismounting plate 402, and the dismounting plate 402 is provided with a dismounting rod 403. The material collecting box 401 is below the clamping plate 602.

[0047] It should be noted that when the carrier frame 306 is shaken, the crystallized impurities shaken off fall into the material collecting box 401. When it is necessary to clean the impurities, the dismounting plate 402 is pulled out of the material collecting box 401 through the dismounting rod 403 for impurity cleaning.

[0048] As shown in Figure 3 The bottom of the main cylinder 101 is provided with an anti-falling rod, and the bottom of the rotating shaft 302 is provided with a butt joint hole. When the main cylinder 101 and the top cover body 201 are installed, the rotating shaft 302 is sleeved on the anti-falling rod through the butt joint hole to keep stable when the rotating shaft 302 rotates.

[0049] It should be noted that when installing the main cylinder 101 and the top cover body 201, the rotating shaft 302 is sleeved on the anti-off rod through the butt joint hole, when the rotating shaft 302 drives the carrier assembly 3 to rotate to the middle position of the flow divider 501, the water suction pump 503 sucks the wastewater at the bottom of the main cylinder 101 through the water suction pipe 502, and sprays out through the water spray hole, respectively to the water suction carrier 308 on both sides of a carrier frame 306, the water suction carrier 308 stores the wastewater, and the heating carrier 307 heats the water suction carrier 308, because the boiling point of trimethylamine is much lower than that of water, by heating the wastewater containing water, the trimethylamine is preferentially vaporized into a gaseous state, and the water and other high-boiling-point components remain in the liquid phase, thereby evaporating the trimethylamine in the water suction carrier 308, and recycling through the first gas outlet pipe 202, thereby realizing the recycling effect of trimethylamine, when the trimethylamine recycling is completed, the heating carrier 307 further heats the water suction carrier 308, at this time, under the action of high temperature, the remaining impurities in the water suction carrier 308 are crystallized, and the crystallized impurities are stored in the water suction carrier 308, in the process of crystallization, the gas impurities generated are discharged through the second gas outlet pipe 203, as the rotating shaft 302 continuously drives the water suction carrier 308 and the heating carrier 307 to rotate, the water suction carrier 308 and the heating carrier 307 contact the shaking assembly 6, and enter between the clamping plates 602 under the guidance of the guide chute, because the number of guide balls 603 on different clamping plates 602 is different, the number of clamping plates 602 is two, one of which is arranged on the support bottom ring 103, and the other is arranged at the bottom of the support top ring 204, the guide balls 603 are distributed in a staggered manner, under the limiting action of the guide balls 603 and the elastic force of the shaking spring 605, the carrier frame 306 is in an up-down shaking state, and the crystallized impurities are shaken off, under the action of the guide spring 604, the clamping plate 602 receives an increased elastic force, thereby intensifying the shaking of the carrier frame 306, and shaking off the crystallized impurities, in the process of rotating and shaking the carrier frame 306 driven by the rotating shaft 302, the support bottom ring 103 and the support top ring 204 are used for limiting the carrier frame 306 in the rotating process and resetting the carrier frame 306 in the shaking process, that is, when the carrier frame 306 finishes shaking, the support bottom ring 103 and the support top ring 204 limit the carrier frame 306 again, keep the normal movement of the carrier frame 306, and reduce the content of impurities in the wastewater at the bottom of the main cylinder 101, when the carrier frame 306 is shaken, the shaken-off crystallized impurities fall into the material collecting box 401, when it is necessary to clean the impurities, the disassembly plate 402 is pulled out from the material collecting box 401 through the disassembly rod 403 for cleaning the impurities.
