Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, in particular to a recovery device for methyl tert-butyl ether. Background Art

[0002] In the traditional chemical processing technology, the production of methyl tert-butyl ether requires the recovery of methanol in the mixture of methanol and C4. The existing water washing tower recovery device recovers water and methanol by reaction through water washing, but the existing water washing tower devices all spray water through atomizing nozzles. Compared with ordinary nozzles, the water outlet of this atomizing nozzle is relatively small, and then the residual dust and other impurities in the water accumulate in the water outlet of the atomizing nozzle, and the water outlet of the atomizing nozzle is more easily blocked, so the atomizing nozzle needs to be improved or replaced;

[0003] The Chinese patent number cited is CN115894183B, which discloses a device for recovering methyl tert-butyl ether, including: a hollow cylindrical reaction tank arranged in a vertical state; a tank cover fixedly connected to the reaction tank coaxially by bolts, and a motor fixedly arranged at the upper end of the tank cover; a water storage cylinder, which can store and input pressurized water into the reaction tank; a water washing component, including a plurality of spraying mechanisms, each of which is fixedly connected to the water storage cylinder, and each of which includes two water washing mechanisms, and the water washing mechanisms can spray water evenly and react with methanol; a rotating component, which is fixedly arranged coaxially with the reaction tank, and the rotating component includes a rotating shaft and a plurality of interactive mechanisms, and the rotating shaft is arranged in a vertical state, one end of the rotating shaft is fixedly connected to the output end of the motor, and the other end extends into the water storage cylinder and is fixedly connected coaxially with the water storage cylinder, and the interactive mechanism is hinged with the two water washing mechanisms, and each interactive mechanism can drive the corresponding two water washing mechanisms to perform alternating displacement in the vertical direction;

[0004] This patent solves the problem that the output of water flow is uncontrollable, excess water flow output will cause waste, and methyl tert-butyl ether far away from the injection port will be incompletely cleaned due to factors such as slower water flow rate and reduced water purity. However, the traditional recovery device has a low reaction speed and low working efficiency. Therefore, it is necessary to invent a methyl tert-butyl ether recovery device that can react quickly and fully. Summary of the invention

[0009] Preferably, the heating mechanism comprises a water tank, a water pump is fixedly connected to the top of the water tank, a water pipe is fixedly connected to the top of the water tank, a water delivery port is fixedly connected to the end of the water pipe away from the water tank, a high-temperature steam generator is fixedly connected to the top of the water pump, a connecting sleeve is fixedly connected to the output end of the high-temperature steam generator, a heat insulation plate is fixedly connected to the outside of the connecting sleeve, a cross jet pipe is rotatably connected to the inside of the connecting sleeve, jet ports are provided at the end of the cross jet pipe, a rotating shaft four is fixedly connected to the top of the cross jet pipe, a heat conduction plate is fixedly connected to the outside of the rotating shaft four, a friction plate two is fixedly connected to the inside of the heat conduction plate, and four friction plates two are provided.

[0010] Preferably, the oscillation mechanism comprises motor 2, the outer side of the motor 2 is clamped with a protective sleeve 2, the bottom of the protective sleeve 2 is fixedly connected to a fixed platform, the output end of the motor 2 is fixedly connected to a rotating shaft 3, the end of the rotating shaft 3 away from the motor 2 is fixedly connected to a power block, the top of the power block is provided with a fixed disk, the side of the fixed disk is fixedly connected with a connecting plate, the bottom of the connecting plate is fixedly connected with telescopic tube 2, the end of the telescopic tube 2 away from the connecting plate is fixedly connected to the bottom plate, the outer side of the telescopic tube 2 is provided with spring 2, the top of the connecting plate is fixedly connected with connecting rod 2, the top of the connecting rod 2 is fixedly connected with a mounting rod, the outer side of the mounting rod is fixedly connected with an oscillation plate, and five oscillation plates are provided.

[0011] The present invention provides a recovery device for methyl tert-butyl ether. The device has the following beneficial effects:

[0012] 1. The methyl tert-butyl ether recovery device is provided with an oscillation mechanism. The motor 2 drives the power block to rotate. The power block is provided in a semicircular shape. When the arc of the power block contacts the fixed disk, the fixed disk is lifted, thereby lifting the oscillation plate upward through the connecting rod 2. When the arc of the power block is separated from the fixed disk, the oscillation plate is driven to vibrate under the action of multiple springs 2, thereby vibrating the methanol and waste liquid inside. In this way, the methanol and waste liquid can be fully reacted while the reaction speed is accelerated, thereby improving the work efficiency.

[0013] 2. The methyl tert-butyl ether recovery device pours water from the water supply port through the setting of the heating mechanism. The water enters the water tank through the water supply pipe. The water in the water tank is pumped into the high-temperature steam generator through a water pump, thereby generating high-temperature water vapor and spraying it out from the jet port. Since the heat conduction plate has good thermal conductivity, the heat can be quickly transferred into the reaction box, so that the reaction speed is accelerated, thereby improving the work efficiency. The heat insulation plate can prevent the heat of the water vapor from diffusing to the bottom of the heating box, causing the heat to be lost, thereby accelerating the heating speed of the solution. At the same time, the rotating shaft 4 drives the cross jet pipe to rotate, which can drive the jet port to rotate quickly, so that the water vapor is distributed circumferentially, avoiding uneven heating of the reaction box caused by uneven distribution of water vapor, thereby causing poor reaction effect.

[0014] 3. The methyl tert-butyl ether recovery device is provided with a stirring reaction mechanism. The motor drives the rotating shaft to rotate, the rotating shaft drives the pinion to rotate, and the pinion drives the stirring blade to rotate. If the connecting block connects the connecting rod 1 and the connecting rod 2 together through a latch, the stirring blade can be driven to revolve, and the pinion can drive the stirring blade to rotate. In this way, the solutions can be stirred more fully by rotating and revolving at the same time. At the same time, the spiral blades can transport the solution to the bottom of the reaction box, so that the stirring is more uniform and thorough, avoiding uneven reaction of the solutions in various places in the reaction box, resulting in poor reaction effect, thereby improving work efficiency and accelerating reaction speed.

[0015] 4. The methyl tert-butyl ether recovery device has friction plates 1 and 2 arranged so that motor 1 drives the stirring blade to rotate and revolve, and at the same time drives friction plate 1 to rotate through telescopic tube 1. Whenever friction plate 1 rotates and contacts friction plate 2, since friction plate 1 and friction plate 2 are both arranged as arc surfaces, friction plate 1 is pressed toward friction plate 2 under the action of spring 1, thereby generating heat by friction, generating a large amount of heat, which can further heat the solution, thereby accelerating the reaction rate, allowing methanol to fully react with waste liquid, thereby obtaining methyl tert-butyl ether faster and more fully, making the production speed of methyl tert-butyl ether faster, collecting faster, and working efficiency higher.
