[0015] The present invention provides an o-chlorobenzaldehyde reactor hydrolysis exhaust device through improvement, which has the following improvements and advantages compared with the prior art: First, the present invention provides a liquid spray unit. When more hydrogen chloride is generated during the production of o-chlorobenzaldehyde, the gas pressure in the reactor body increases, so that the gas passing through the gas outlet pipe pushes the sliding tube to move. The movement of the sliding tube increases the gas outlet hole, thereby increasing the gas displacement. The movement of the sliding tube drives the fixed rack to move. The movement of the fixed rack drives the rotating gear and the rotating shaft to rotate. At the same time, the rotating shaft drives the valve to rotate. The valve rotates to increase the flow rate of the treated liquid, so that when the discharged gas increases, the amount of liquid sprayed increases, so that the treated liquid and the gas can be fully neutralized, thereby improving the neutralization effect of the hydrogen chloride gas.

[0016] Secondly, through the setting of the driving unit, the driving motor rotates through two bevel gears to drive the rotating rod and the turntable to rotate, the rotation of the turntable drives the cylindrical rod to rotate in a circle, the rotation of the cylindrical rod drives the fixed bar and the spray pipe to swing, the swing of the spray pipe can spray liquid evenly, when the hydrogen chloride generation rate increases, the speed of the driving motor also increases synchronously, so that the swing frequency of the spray pipe is accelerated, and the spraying effect is improved.

[0017] Thirdly, the present invention arranges a stirring unit, and the swing of the liquid spray pipe drives the fixed rod, the fixed shaft and the fixed block to swing.

The rotation of the fixed block can break up the gas entering the box. When the speed of the driving motor increases, the swing frequency of the fixed rod increases, and the rotation speed of the fixed shaft increases, the meshes of the sliding filter plate and the fixed filter plate are misaligned, and then the meshes become smaller, thereby effectively improving the slow flow effect on the gas to match the increase in the generation rate of hydrogen chloride, thereby improving the neutralization effect of the solution and the gas.

[0018] Fourthly, the present invention arranges a swinging unit so that the swinging of the fixed rod drives the swinging of the extrusion rod, the swinging of the extrusion rod drives the U-shaped bar and the connecting rod to move back and forth, the reciprocating movement of the connecting rod drives the bar block, the rotating column and the air guide plate to swing, and the swinging of the air guide plate can expand the spraying range of the gas, so that the gas can be evenly dispersed, and the dispersed gas can be fully neutralized with the evenly sprayed solution.

Through the setting of the driving unit, the driving motor 2 rotates to drive the rotating rod 23 and the turntable 25 to rotate through the two bevel gears 28. The rotation of the turntable 25 drives the cylindrical rod 26 to rotate in a circle. The rotation of the cylindrical rod 26 drives the fixing bar 27 and the liquid spraying pipe 13 to swing.

[0031] It should be noted that: in order to better control the reaction, the speed of the driving motor 2 in the present application is from low to high and then to low to match the early, middle and late stages of the hydrolysis reaction, so as to achieve a positive correlation between the exhaust gas generation rate and the speed of the driving motor 2.

[0032] Working principle: During the production of o-chlorobenzaldehyde, the generated hydrogen chloride gas enters the box body 12 through the outlet pipe 11, and water enters the spray pipe 13 through the external water pipe 14, and then is sprayed out from the spray pipe 13. The hydrogen chloride gas is neutralized by the solution and converted into harmless salts. The driving motor 2 drives the driving shaft 21 and the stirring rod 22 to rotate. The stirring rod 22 rotates to stir the raw materials. When the generation of hydrogen chloride increases, the gas pressure in the reactor body 1 increases, so that the gas passing through the outlet pipe 11 pushes the sliding pipe 17 to move, and the movement of the sliding pipe 17 makes The air outlet 18 is enlarged, thereby increasing the gas discharge volume, the sliding tube 17 moves to drive the fixed rack 19 to move, the fixed rack 19 moves to drive the rotating gear 110 and the rotating shaft 111 to rotate, the rotating shaft 111 rotates to drive the torsion spring 112 to rotate and elastically deform, and at the same time the rotating shaft 111 drives the valve 15 to rotate, the valve 15 rotates to increase the flow rate of the treated liquid, so that when the discharged gas increases, the amount of liquid sprayed increases, so that the treated liquid and the gas can be fully neutralized, thereby improving the neutralization effect of the hydrogen chloride gas; the driving motor 2 rotates to drive the two bevel gears 28 to drive The rotating rod 23 and the rotating disk 25 rotate, and the rotation of the rotating disk 25 drives the cylindrical rod 26 to rotate in a circle. The rotation of the cylindrical rod 26 drives the fixed bar 27 and the spray pipe 13 to swing. The swing of the spray pipe 13 can spray liquid evenly. The swing of the spray pipe 13 drives the fixed rod 3, the fixed shaft 31 and the fixed block 24 to swing. The swing of the fixed rod 3 drives the extrusion rod 45 to swing. The swing of the extrusion rod 45 drives the U-shaped bar 44 and the connecting rod 43 to reciprocate. The reciprocating movement of the connecting rod 43 drives the bar block 42, the rotating column 4 and the air guide plate 41 to swing. The swing of the air guide plate 41 can expand the air The spray range of the body makes the gas evenly dispersed, and the dispersed gas can be fully neutralized with the evenly sprayed spray liquid. The swing of the fixed shaft 31 drives the fixed gear 32 to move and rotate on the arc rack 33. The rotation of the fixed gear 32 drives the fixed shaft 31 and the fixed block 24 to rotate. The rotation of the fixed block 24 can disperse the gas entering the box body 12. The setting of the fixed filter plate 35 and the sliding filter plate 36 can block the gas sprayed from the outlet pipe 11, so that the gas can achieve a slow flow effect, increase the spraying time of the gas, and ensure the treatment effect of the exhaust gas.When the generation rate of hydrogen chloride increases, the speed of the driving motor 2 also increases synchronously, so that the swing frequency of the liquid spray pipe 13 is accelerated, and the spraying effect is improved. At the same time, the swing frequency of the fixed rod 3 increases, the rotation speed of the fixed shaft 31 increases, and the fixed block 24 rotates so that the sliding filter plate 36 moves outward under the action of the increased centrifugal force. The movement of the sliding filter plate 36 drives the telescopic spring 37 to stretch and elastically deform. At this time, the mesh of the sliding filter plate 36 and the fixed filter plate 35 is misaligned, and then the mesh becomes smaller, thereby effectively improving the slow flow effect on the gas to match the increase in the generation rate of hydrogen chloride, and improving the neutralization effect of the solution and the gas. When a small amount of gas floats to the inner wall of the box 12, the gas falls and gathers toward the middle along the V-shaped plate 5. The solution sprayed on the mesh plate 51 falls through the mesh, forming a secondary spraying effect. Finally, the treated liquid falls into the bottom of the box 12 through the drain port 52 for collection. ;
