Description

Technical Field

[0001] The invention relates to the technical field of acetal recovery, in particular to an acetal condensation recovery device with a safety and leakage prevention function. Background Art

[0002] Acetal, also known as acetaldehyde acetal, is an organic chemical that is often used as a solvent, chemical raw material and reaction intermediate in organic synthesis, coatings, rubber, plastics, textiles and electronics. Acetal itself is highly volatile and easy to evaporate and form steam. Acetal is often used as an intermediate for synthesizing other chemicals, especially in the production process of alcohol compounds, plastics, coatings, etc. However, due to the volatility of acetal, especially during its evaporation process, harmful gases in the air are often formed; or acetal vapor is discharged into the air, which will lead to a decrease in air quality and ecological environment problems. The most common way to protect the ecological environment is to condense and recover acetal. When acetal vapor enters the condensation system, the temperature difference is used to condense the acetal gas into a liquid for recovery. This method usually uses a cooling device or a condenser to cool the acetal vapor below its condensation point to convert it into a liquid. However, existing condensation recovery devices usually use steam to contact the cooling device to transfer the low temperature to the gas, so that the gas reaches the condensation temperature. However, this direct contact method consumes too much time, and the condensation temperature cannot be reached immediately after one transportation contact. Continuous circulation transportation is required, which makes the gas condensation efficiency low. Summary of the invention

The acetal vapor is then transported to the recovery tank through the steam tank, so that the acetal vapor is condensed in the recovery tank. After the temperature of the acetal vapor in the recovery tank drops, it condenses to form liquid droplets, thereby achieving the effect of acetal condensation recovery. Finally, the acetal liquid is transported to the liquid storage chamber and finally transported out.

[0005] Preferably, a heat-insulating layer is provided in the inner wall of the steam tank, an air supply ring is provided on the side of the steam tank away from the air inlet ring, an air pump is provided inside the air supply ring, a plurality of air supply pipes are provided on the axial arm of the air supply ring, and a pressure valve is provided on the side of the air supply ring close to the air supply pipe.

[0006] Preferably, the gas supply pipe is connected to the recovery tank, and the gas supply pipe corresponds to the recovery tank one by one.

[0007] Preferably, the recovery tank is composed of a bottom plate, a plurality of moving blocks and a rotating ring, the plurality of moving blocks are located between the bottom plate and the rotating ring, and the plurality of moving blocks are arranged around the axis of the bottom plate.

[0008] Preferably, a plurality of movable grooves are arranged on the top of the bottom plate, a sliding block is arranged on the bottom of the movable block, and the movable block is slidably connected to the movable grooves via the sliding block.

[0009] Preferably, the rotating ring is composed of an inner plate and an outer ring, a plurality of brackets are arranged between the inner plate and the outer ring, a toggle groove is arranged on the bracket, a toggle rod is arranged on the top of the moving block, and the moving block is slidably connected to the toggle groove through the toggle rod.

[0010] Preferably, two adjacent moving blocks are connected in a sliding and sealing manner, and a cooling fin is provided on one side of the moving block close to the axis of the bottom plate.

[0011] Preferably, a liquid storage cavity is provided on the side of the gas transmission ring away from the steam tank, a plurality of connecting pipes are provided on the top of the liquid storage cavity, an outlet is provided at the bottom of the bottom plate, and a solenoid valve is provided in the outlet.

[0012] Preferably, the diameter of the outlet is the same as the diameter of the connecting pipe, the gas supply pipe is located inside the connecting pipe, and the diameter of the connecting pipe is larger than the diameter of the gas supply pipe.

[0013] Preferably, a driving gear is provided on the top of the steam tank, and the driving gear is rotatably connected to the steam tank. A driving gear is provided on the top of the recovery tank, and the driving gear is connected to a rotating ring. The driving gear and the driving gear are meshed for transmission. A motor is provided on the top of the body, and the driving shaft of the motor is connected to the driving gear.

[0014] After the acetal vapor is transported to the steam tank, the temperature of the acetal vapor in the steam tank is kept warm because the inner wall of the steam tank is provided with an insulation layer, which does not cause a large-scale temperature drop. Then the controller controls the air pump in the gas transmission ring to start. At this time, the pressure valve in the gas transmission pipe is in an open state, and the solenoid valve in the outlet is in a closed state. Then the air pump transports the acetal vapor from the steam tank to the gas transmission ring, and then transports it to the gas transmission pipe through the gas transmission ring, and finally transports it to the recovery tank through the gas transmission ring. Before the acetal vapor is transported, the controller controls the motor to rotate, and the driving shaft of the motor then drives the driving gear to rotate, and the driving gear drives a number of driving gears to rotate, and the driving gear drives the rotating ring to rotate during the rotation process, so that the rotating ring drives the toggle slot to rotate, and then the toggle slot drives the toggle rod on the top of the moving block to move, and at this time the moving block moves to the side close to the axis of the bottom plate, so that the diameter of the space surrounded by the several moving blocks is the same as the diameter of the outlet, and while the moving block moves, the controller controls the refrigeration plate on the moving block to start; Since two adjacent moving blocks are connected in a sliding seal, and the solenoid valve in the outlet is in a closed state at this time, the space surrounded by several moving blocks is a closed space, and acetal vapor is continuously transported to the recovery tank through the gas pipe. When the gas pressure in the recovery tank continues to rise, the pressure valve monitors the pressure on the side of the gas pipe away from the gas transmission ring in real time, and the pressure valve converts the pressure signal into an electrical signal and transmits it to the controller. When the pressure in the recovery tank reaches the maximum pressure value, the pressure valve is closed; After the acetal vapor is transported to the recovery tank, the acetal vapor contacts the side wall of the moving block, and the low temperature generated by the refrigeration plate on the moving block is transferred to the acetal vapor, so that the temperature of the acetal vapor drops and condenses on the surface of the moving block to form liquid droplets. While the refrigeration plate cools the acetal vapor, the controller controls the motor to reverse, and the driving shaft of the motor drives the driving gear to reverse, and then the driving gear drives the rotating ring to reverse. During the reversal of the rotating ring, the toggle groove is driven to rotate in the opposite direction, and then the moving block moves to the side away from the axis of the bottom plate. The moving block moves along the moving groove through the slider, so that the space surrounded by the several moving blocks increases, and then the diameter of the space surrounded by the several moving blocks is greater than the diameter of the outlet; In a confined space, after the volume of the space expands, the pressure of the gas filled in the space decreases immediately. As the gas pressure decreases, the temperature of the acetal vapor itself also decreases, and cooperates with the low temperature generated by the refrigeration plate to further improve the cooling efficiency of the acetal vapor, so that the acetal vapor reaches the condensation temperature faster, shortening the condensation time of the acetal vapor, thereby improving the condensation efficiency of the acetal vapor; The acetal liquid droplets formed by condensation flow down along the surface of the moving block, and then the controller controls the solenoid valve in the outlet to open, and the liquid droplets are transported to the connecting pipe through the outlet, and then the liquid droplets are transported to the liquid storage chamber through the connecting pipe for storage, so that the acetal is subsequently recycled and processed, avoiding the acetal from being discharged into the environment, causing damage to the ecological environment and pollution of the environment, thereby protecting the ecological environment; When the pressure in the recovery tank drops, after a period of time after the solenoid valve is opened, the controller controls the solenoid valve to close again and the pressure valve to open again; at the same time, the motor is driven again under the action of the controller, so that the several moving blocks move again toward the axis close to the bottom plate, so that the space surrounded by the several moving blocks is reduced again, preparing for the next expansion of the space, so that the pressure of the acetal vapor drops, and then the temperature of the acetal vapor drops.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the initial air intake stage, several moving blocks are moved inward, so that the volume of the space surrounded by the several moving blocks is smaller. As the acetal vapor is continuously input into the recovery tank, the gas pressure in the recovery tank is continuously increased. When the pressure value is reached, several moving blocks are moved outward, so that the volume of the space surrounded by the several moving blocks is increased. Then, when the unit gas volume in the space is equal, the unit gas pressure will decrease when the space becomes larger, and then the gas temperature will also decrease, that is, the temperature of the acetal vapor itself will also decrease, and cooperate with the low temperature generated by the refrigeration plate to further improve the cooling efficiency of the acetal vapor, so that the acetal vapor reaches the condensation temperature faster, shortens the condensation time of the acetal vapor, and thus improves the condensation efficiency of the acetal vapor.

[0016] 2. Since two adjacent moving blocks are connected by sliding seals, and the solenoid valve in the outlet is in a closed state at this time, the space surrounded by several moving blocks is a closed space, and the acetal vapor is continuously transported to the recovery tank through the gas pipe. At this time, after entering the recovery tank, the acetal vapor can only flow in the recovery tank and cannot leak out through the gap between the two adjacent moving blocks, thereby achieving the safe and effective condensation of liquid droplets of acetal vapor during the condensation recovery process, thereby achieving a safe and leak-proof effect.

[0027] Working principle of the present invention: The acetal vapor is transported to the air inlet 12 through the pipeline, and then transported to the air inlet ring 11 through the air inlet 12, and then enters the steam tank 13 through the air inlet ring 11. After the acetal vapor is transported to the steam tank 13, since the inner wall of the steam tank 13 is provided with a heat preservation layer, the temperature of the acetal vapor in the steam tank 13 is kept warm, and a large range of temperature drops will not be caused. Then the controller controls the air pump in the air delivery ring 15 to start. At this time, the pressure valve in the air delivery pipe 16 is in an open state, and the solenoid valve in the outlet 172 is in a closed state, and then the air pump transports the acetal vapor from the steam tank 13 to the air delivery ring 15, and then transports it to the air delivery pipe 16 through the air delivery ring 15, and finally transports it to the recovery tank 14 through the air delivery ring 15; Before the acetal vapor is transported, the controller controls the motor to rotate, and the driving shaft of the motor then drives the driving gear 22 to rotate. When the driving gear 22 rotates, it drives a number of driving gears 23 to rotate. During the rotation of the driving gear 23, the rotating ring 19 is driven to rotate, so that the rotating ring 19 drives the toggle slot 191 to rotate, and then the toggle slot 191 drives the toggle rod on the top of the moving block 18 to move. At this time, the moving block 18 moves to the side close to the axis of the bottom plate 17, so that the diameter of the space surrounded by the several moving blocks 18 is the same as the diameter of the outlet 172. When the moving block 18 moves, the controller controls the refrigeration plate on the moving block 18 to start; Since two adjacent moving blocks 18 are connected in a sliding seal, and the solenoid valve in the outlet 172 is in a closed state at this time, the space surrounded by the moving blocks 18 is a closed space, and the acetal vapor is continuously transported to the recovery tank 14 through the gas pipe 16. When the gas pressure in the recovery tank 14 continues to rise, the pressure valve monitors the pressure on the side of the gas pipe 16 away from the gas ring 15 in real time, and the pressure valve converts the pressure signal into an electrical signal and transmits it to the controller. When the pressure in the recovery tank 14 reaches the maximum pressure value, the pressure valve is closed. After the acetal vapor is transported to the recovery tank 14, the acetal vapor contacts the side wall of the moving block 18, and the low temperature generated by the refrigeration plate on the moving block 18 is transferred to the acetal vapor, so that the temperature of the acetal vapor drops and condenses on the surface of the moving block 18 to form liquid droplets. While the refrigeration plate cools the acetal vapor, the controller controls the motor to reverse, and the driving shaft of the motor drives the driving gear 22 to reverse, and then the driving gear 23 drives the rotating ring 19 to reverse. During the reversal of the rotating ring 19, the toggle groove 191 is driven to rotate in the opposite direction, and then the moving block 18 moves to the side away from the axis of the bottom plate 17. The moving block 18 moves along the moving groove 171 through the slider, so that the space surrounded by the plurality of moving blocks 18 increases, and then the diameter of the space surrounded by the plurality of moving blocks 18 is greater than the diameter of the outlet 172; In a confined space, as the volume of the space expands, the pressure of the gas filled in the space decreases immediately. As the gas pressure decreases, the temperature of the acetal vapor itself also decreases, and cooperates with the low temperature generated by the refrigeration plate, so that the acetal vapor reaches the condensation temperature faster; The condensed acetal droplets flow down the surface of the moving block 18, and then the controller controls the solenoid valve in the outlet 172 to open, and the droplets are transported to the connecting pipe 21 through the outlet 172, and then the droplets are transported to the liquid storage chamber 20 through the connecting pipe 21 for storage; When the pressure in the recovery tank 14 drops, after a period of time after the solenoid valve is opened, the controller controls the solenoid valve to close again and the pressure valve to open again; at the same time, the motor is driven again under the action of the controller, so that the plurality of moving blocks 18 move again toward the axis close to the bottom plate 17, so that the space surrounded by the plurality of moving blocks 18 is reduced again, in preparation for the next expansion of the space, so that the pressure of the acetal vapor is reduced, and then the temperature of the acetal vapor is reduced.
