Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of alkali recovery devices, specifically a methanol-to-olefins waste alkali recovery device with a pretreatment structure. Background Technology
[0002] Ethylene, propylene, and other low-carbon olefins are important basic chemical raw materials. The methanol-to-ethylene (MTO) and methanol-to-propylene (MTP) processes are crucial chemical technologies. These technologies use methanol synthesized from coal or natural gas as raw material to produce low-carbon olefins and are core technologies for developing the production of ethylene, propylene, and other products from non-petroleum resources.
[0003] In the prior art, alkaline solutions are collected in one tank for processing, which cannot effectively separate solids from liquids. This results in the simultaneous dumping of solids and liquids when the liquid is poured out after processing, requiring additional sorting in the future. Therefore, those skilled in the art have provided a methanol-to-olefins waste alkaline solution recovery device with a pretreatment structure to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this invention is to provide a methanol-to-olefins waste alkaline solution recovery device with a pretreatment structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a methanol-to-olefins waste alkaline liquid recovery device with a pretreatment structure, comprising a base, a motor fixedly embedded in the top of the base, a connecting plate fixedly sleeved on the outer wall of the output shaft of the motor, two connecting plates symmetrically fixedly connected to the outer wall of the connecting plate, and mounting plates fixedly connected to the top of each of the two connecting plates, a first storage tank and a second storage tank respectively penetrating through the top of the mounting plates, a connecting pipe connecting the first storage tank and the second storage tank, a fan fixedly embedded in the connecting pipe, a first top cover sealed to the opening of the first storage tank, a mounting pipe fixedly connected to the bottom of the first top cover, multiple cooling pipes horizontally arranged and fixedly connected to the inner wall of the mounting pipe, a second top cover sealed to the opening of the second storage tank, and a heater fixedly embedded in the top of the second top cover.
[0006] As a further improvement of this utility model: the top of the mounting plate has two symmetrical cross holes, and the bottom of the first storage tank and the second storage tank are both fixedly connected with cross rods, and the two cross rods are respectively engaged in the two cross holes.
[0007] As a further improvement of this utility model: the air outlet of the fan faces into the first storage tank, and the mounting tube is located on the upper side of the fan.
[0008] As a further improvement of this utility model: As a further improvement of this utility model: Two support blocks are symmetrically fixedly connected to the bottom of the mounting plate, and the bottom of the two support blocks and the top of the base are in contact with each other.
[0009] As a further improvement of this utility model: a circular groove is provided on the top of the base, and the motor is fixedly embedded in the circular groove.
[0010] The first and second storage tanks are the same size, and the bottom of the first storage tank and the top of the mounting plate are tightly fitted together.
[0011] As a further embodiment of this utility model: the bottom of the first top cover and the second top cover are respectively snapped into the first storage tank and the second storage tank, and the plurality of the first storage tanks and the second storage tanks are arranged symmetrically in a vertical arrangement.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] When the second storage tank rotates in a circular motion, it generates centrifugal force to separate the solid and liquid components of the alkali solution inside. When the second top cover is opened, the alkali solution in the second storage tank can be heated, which will generate water vapor and rise. Then, the fan is turned on to draw the water vapor into the first storage tank through the connecting pipe. Multiple cooling pipes are installed in the pipe. When the water vapor enters the first storage tank and rises, it will come into contact with the multiple cooling pipes and be cooled. After the water vapor is cooled, it will liquefy and fall into the first storage tank for collection. When the alkali solution in the second storage tank is completely evaporated, a solid will remain.
[0014] This invention is simple to use. When the second storage tank is driven by a motor to perform circular motion, it can generate centrifugal force to cause the solids in the alkali solution to precipitate at the bottom of the liquid for pretreatment. Furthermore, the water vapor generated by the heated alkali solution in the second storage tank can be transported to the first storage tank by a fan. The alkali solution in the second storage tank can be completely evaporated to form a solid, thereby allowing the solid and liquid to be stored separately for convenient subsequent classification and processing.

A first top cover 6 is sealed and fitted to the opening of the first storage tank 5. A mounting pipe 14 is fixedly connected to the bottom of the first top cover 6. Multiple cooling pipes 15 are horizontally arranged and fixedly connected to the inner wall of the mounting pipe 14. A second top cover 9 is sealed and fitted to the opening of the second storage tank 7. A heater 8 is fixedly embedded in the top of the second top cover 9. After lifting the second top cover 9, alkali liquid can be poured into the second storage tank 7.
[0023] In this embodiment, two cross holes 12 are symmetrically opened on the top of the mounting plate 4, and cross rods 13 are fixedly connected to the bottom of the first storage tank 5 and the second storage tank 7, respectively, and the two cross rods 13 are respectively engaged in the two cross holes 12.
[0024] In this embodiment, the air outlet of the fan 10 faces into the first storage tank 5, and the mounting tube 14 is located above and to the side of the fan 10.
[0025] In this embodiment, two support blocks 2 are symmetrically fixedly connected to the bottom of the mounting plate 4, and the bottom of the two support blocks 2 and the top of the base 1 are in contact with each other.
[0026] In this embodiment, a circular groove is provided on the top of the base 1, and the motor 11 is fixedly embedded in the circular groove.
[0027] In this embodiment, the first storage tank 5 and the second storage tank 7 are the same size. The bottom of the first storage tank 5 and the second storage tank 7 and the top of the mounting plate 4 are tightly fitted together. The first storage tank 5 and the second storage tank 7 are installed in the mounting plate 4 by being snapped together by the cross rod 13.

[0029] The working principle of this utility model is as follows: The starting motor 11 drives the connecting plate 17 to rotate. After the connecting plate 17 rotates, it can drive the connecting plate 3, the mounting plate 4, the first storage tank 5, and the second storage tank 7 to perform circular motion. When the second storage tank 7 performs circular motion, it can generate centrifugal force to separate the solid and liquid of the alkali solution inside. When the second top cover 9 is started, the alkali solution in the second storage tank 7 can be heated. At this time, water vapor will be generated and rise. Then, the fan 10 is started to draw the water vapor into the first storage tank 5 through the connecting pipe 16. Multiple cooling pipes 15 are set in the mounting pipe 14.

At this time, the water vapor will liquefy after cooling and fall into the first storage tank 5 for collection. When the alkali solution in the second storage tank 7 is completely evaporated, solid will remain. Therefore, the first storage tank 5 and the second storage tank 7 can simultaneously store liquid and solid, thereby achieving the function of solid-liquid separation.
