Description

Technical Field

[0001] The present invention relates to the technical field of DMMn production, and specifically to a novel reaction device for DMMn. Background Art

[0002] DMMn (polymethoxydimethylethers) is a new type of environmentally friendly fuel blending component recognized internationally for reducing fuel consumption and flue gas emissions. When reacting, formaldehyde solution and methylal are usually used for the reaction. The polymerization reaction of methylal and trioxane usually involves an acetalization process, in which trioxane may first decompose into formaldehyde, and then formaldehyde and methylal undergo a condensation reaction under the action of a catalyst to form polymethoxydimethylethers (DMMn). Since the reaction between formaldehyde solution and methylal is an exothermic reaction, the temperature will gradually increase, and high temperature may have an adverse impact on the reaction selectivity, product stability, and the material of the reaction equipment, etc.

[0003] However, when the existing novel reaction device for DMMn is in use, the feeding is not dispersed and uniform enough, affecting the reaction efficiency and effect; during the reaction, the temperature will be uneven, which is not convenient for comprehensively detecting the temperature of the solution. Usually, the method of overall cooling of the solution is adopted. However, this cooling method not only has a slow cooling speed and poor effect, but also easily affects the temperature of other solutions within the normal temperature range, thereby affecting the reaction efficiency and effect; when feeding raw materials, since the temperature of the raw materials is relatively low, it will also affect the reaction temperature, thereby affecting the reaction efficiency and effect.

At the same time, the solenoid valve is opened and the feeding pump is started. At this time, the raw materials in the storage tank can enter the second stirring cover through the feeding pipe and enter the reaction tank through the feeding holes, which is more dispersed and uniform, and can improve the efficiency and effect of the reaction.

[0018] (2) This new type of DMMn reaction device, by setting up a lifting mechanism, etc., during the reaction, when the first stirring cover rotates, it can drive the temperature sensor to rotate through the U-shaped frame and the mounting plate. When the rubber wheel rolls along the inclined plane to the bottom of the push plate, it can drive the driving rotating shaft to rotate. At the same time, through the connecting mechanism, it drives the spring rotating shaft and the winding roller to rotate, and can loosen the pulling rope. At this time, the first moving plate can move downward under the action of the first spring. At the same time, through the reset mechanism, it drives the second moving plate to move downward. When the temperature sensor detects that the temperature of the liquid at a certain depth is relatively high, the first electromagnet is energized. After the first electromagnet is energized, it attracts the iron block, causing the moving block to move towards the fixed block. At the same time, the third spring is compressed, and the plug is inserted into the jack after abutting against the rubber block.

At the same time, it can reduce the impact on the temperature of the liquid at other depths and ensure the efficiency and effect of the reaction. When the temperature sensor detects that the temperature of the liquid below is within the normal range, the second electromagnet is energized, which can attract the iron ring and drive the circular ring to move towards the second stop block. The fourth spring is compressed. At the same time, it can drive the connecting key to withdraw from the second key groove and slide into the first key groove. At this time, the connection between the driving rotating shaft and the spring rotating shaft is disconnected, and the winding roller can rotate and reset under the action of the spring rotating shaft to wind up the pulling rope, thereby pulling the first moving plate upward. At the same time, the first spring is stretched, which can squeeze the cooling water. At the same time, the second one-way valve opens and the third one-way valve closes. At this time, the cooling water between the first moving plate and the second moving plate can be squeezed and enter the second chamber through the drain pipe, so as to preheat the raw materials in the feed pipe, which can improve the reaction efficiency and effect. At the same time, it is convenient to recycle the heat, which is more energy-saving and environmentally friendly. Then, the first electromagnet is powered off. At this time, the moving block can move and reset away from the fixed block under the action of the third spring and drive the plug to withdraw from the jack. At this time, it can drive the second moving plate to move upward and reset synchronously for subsequent continuous cooling operations. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, through the connecting mechanism, the spring rotating shaft 304 and the winding roller 305 are driven to rotate, and the pulling rope 306 can be loosened. At this time, the first moving plate 1301 can move downward under the action of the first spring 302. At the same time, the second moving plate 1302 is driven to move downward through the reset mechanism. When the temperature sensor 17 detects that the liquid temperature at a certain depth is relatively high, the first electromagnet 804 is energized. After the first electromagnet 804 is energized, it attracts the iron block 805, so that the moving block 203 moves in the direction close to the fixed block 803. At the same time, the third spring 806 is compressed, and the plug 204 is inserted into the jack 201 after abutting against the rubber block 202.

[0046] When the first moving plate 1301 continues to move downward, it can drive the mounting plate 16 and the temperature sensor 17 to continue to move downward. And when the first moving plate 1301 continues to move downward, the second spring 702 is compressed. At this time, a negative pressure is generated between the first moving plate 1301 and the second moving plate 1302. And the second one-way valve opens and the third one-way valve closes. At this time, the cooling water in the cooling box 1304 can enter between the first moving plate 1301 and the second moving plate 1302 through the water supply pipe 1306 and the first hose 1312. At this time, the liquid in this depth range can be locally cooled, which can improve the cooling efficiency and effect. At the same time, it can reduce the influence on the temperature of the liquid at other depths and ensure the efficiency and effect of the reaction.

[0047] When the temperature sensor 17 detects that the temperature of the liquid below is within the normal range, the second electromagnet 905 is energized, which can attract the iron ring 903, drive the circular ring 504 to move towards the direction close to the second stopper 901, and the fourth spring 902 is compressed. At the same time, it can drive the connecting key 503 to withdraw from the second key slot 501 and slide into the first key slot 502. At this time, the connection between the driving rotating shaft 402 and the spring rotating shaft 304 is disconnected, and the winding roller 305 can rotate and reset under the action of the spring rotating shaft 304, and can wind up the pulling rope 306, thereby pulling the first moving plate 1301 to move upward. At the same time, the first spring 302 is stretched, which can squeeze the cooling water. At the same time, the second one-way valve opens and the third one-way valve closes. At this time, the cooling water between the first moving plate 1301 and the second moving plate 1302 can be squeezed and enter the second chamber 1311 through the drain pipe 1308, so as to preheat the raw materials in the feeding pipe 604, improve the efficiency and effect of the reaction, and at the same time, it is convenient to reuse the heat, which is more energy-saving and environmentally friendly.

[0048] Finally, the first electromagnet 804 is powered off. At this time, the moving block 203 can move and reset in the direction away from the fixed block 803 under the action of the third spring 806, and drive the plug pin 204 to withdraw from the jack 201. At this time, it can drive the second moving plate 1302 to move upward and reset synchronously for subsequent continuous cooling operations.
