Description

Technical Field

[0001] The utility model relates to the technical field of flame retardant preparation equipment processing, in particular to a flame retardant polymerization reaction device with waste gas processing. Background Art

[0002] Flame retardants are a specific class of chemical substances whose purpose is to slow down or prevent the spread of flames, thereby reducing the danger and loss of fire. Flame retardant polymerization reaction usually refers to the preparation of polymer materials with specific structures and properties through polymerization reaction in the process of synthesizing flame retardants. However, a series of waste gases will be generated during the flame retardant polymerization process, and these waste gases cannot be discharged into the atmosphere directly. They need to be discharged into the atmosphere after reaction in specific equipment.

[0003] Chinese patent CN220345462U discloses an acid-base waste gas treatment equipment, which relates to the technical field of acid-base waste gas treatment equipment, including a base, a waste gas treatment box is fixedly connected to the top of the base, a spray assembly is fixedly connected to the inside of the waste gas treatment box, and the spray assembly includes a liquid storage tank, a liquid infusion tube is fixedly connected to one side of the liquid storage tank, an infusion pump is fixedly connected to one end of the infusion tube, a liquid inlet tube is fixedly connected to the top of the infusion pump, a nozzle is fixedly connected to the outer wall of the liquid inlet tube, and a support plate is fixedly connected to the bottom of the infusion pump. The utility model can spray the cleaning agent evenly into the waste gas through the liquid storage tank, liquid infusion tube, infusion pump, liquid inlet tube, and nozzle, further promote the contact reaction between the waste gas and the cleaning agent, increase the contact area between the waste gas and the cleaning agent, thereby improving the purification efficiency, and can thoroughly infiltrate and adsorb the pollutants during spraying, which is beneficial to the occurrence of chemical reactions and the denitrification and dust removal of the waste gas. However, there are still defects that can be improved:

[0004] 1. The spray assembly designed in this utility model is horizontally fixed. As we all know, when gas floats, it will float irregularly. Although the utility model is provided with a dry nozzle on the liquid inlet pipe, there is a gap between the nozzles, and the angle is not changeable. When the smoke rises, it will float along these gaps to the top of the treatment box, that is, there will be residual gas in the treatment box.

[0005] 2. The suction pipe of the utility model is directly connected to the processing box. In the whole device, although there are filling layers and adsorption layers to absorb liquid, the liquid will flow down along the box body for a long time and finally gather at the bottom. When a lot of liquid gathers, it will enter the blower along the suction pipe, damage the blower and cause economic losses. Utility Model Content

It is worth noting here that the end of the connecting pipe 4 away from the cyclone separator 3 is located in the box body 5, and a through groove 16 is opened at the bottom of the box body 5 on the side away from the cyclone separator 3, and then a fixing block 17 used in conjunction with the through groove 16 is provided on the inner wall of one side of the box body 5. First, a groove 18 connected to the through groove 16 is opened at the front end of the fixing block 17, and an adsorption plate can be placed in the groove 18. At the same time, in order to ensure that the gas can enter and exit after the adsorption plate is placed, a plurality of through sieve holes 20 are opened on the side of the fixing block 17 away from the through groove 16. In addition, A limiting device 19 is provided at the front of the top of the fixed block 17. When the filtered gas sinks to the bottom of the box body 5, it needs to be sucked out by equipment. An exhauster 21 used in conjunction with the through slot 16 is provided on one side of the box body 5. It is worth noting that the air suction port of the exhauster 21 is connected to the through slot 16. Limiting grooves 12 are provided in the middle and lower parts of the inner walls on both sides of the box body 5. A filter block 13 is provided in the limiting groove 12.

[0034] The above structures together constitute the general appearance structure of the flame retardant polymerization reaction device with waste gas treatment of the utility model.

[0035] In order to further explain the specific working principle of the flame retardant polymerization reaction device with waste gas treatment of the utility model, the above-mentioned limiting device 19 includes a through groove 1901 opened at the front part of the top of the fixed block 17. It is worth noting that the through groove 1901 is connected to the groove 18, and then the through groove 1901 is opened on both sides of the inner wall of the through groove 1901. The two grooves 1902 connected thereto are opened, and then the through groove 1901 is inserted with a positioning pin 1904, and the positioning pin 1904 can slide freely in the through groove 1901. At the same time, springs 1905 are fixedly connected to the top walls of the grooves 1902 on both sides, and the bottom end of the spring 1905 is fixedly connected to a baffle 1903. Finally, the baffles 1903 on both sides are fixedly connected to the positioning pins 1904. It is worth noting that the baffles 1903 can slide freely in the grooves 1902.

[0036] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when stationary, the bottom of the positioning pin 1904 is located in the groove 18, which will limit the movement of the adsorption plate; then when the adsorption plate needs to be replaced, the user pulls the positioning pin 1904 upward, and the positioning pin 1904 will drive the baffles 1903 on both sides to move upward together. When the baffle 1903 moves upward in the groove 1902, it will squeeze the spring 1905 upward. When the bottom of the positioning pin 1904 is completely removed from the groove 18, the user can take out the old adsorption plate and replace it with a new one. Finally, the user releases the positioning pin 1904, and the spring 1905 will restore the baffle 1903 to its original position, and at the same time, the baffle 1903 drives the positioning pin 1904 to return to its original position.

[0037] In order to further explain the specific working principle of the flame retardant polymerization reaction device with exhaust gas treatment of the utility model, the swing device 11 includes a screw 1101 fixedly connected to the output shaft of the motor 14. First, the end of the screw 1101 away from the motor 14 passes through the box 5 and is rotatably connected to the connecting block 1102. It is worth noting that the connecting block 1102 is fixedly connected to the box 5, and then the bottom end of the connecting block 1102 is rotatably connected to a receiving plate 1105, and the nozzle 10 is fixedly connected to the middle of the bottom end of the receiving plate 1105. When the receiving plate 1105 rotates, it will drive the nozzle 10 to rotate synchronously. At the same time, a rotating block 1104 is rotatably connected to the side of the top of the receiving plate 1105 away from the connecting block 1102, and the top of the rotating block 1104 is rotatably connected to a threaded block 1103, and the threaded block 1103 is threadedly connected to the screw 1101.

[0038] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the nozzle 10 needs to be swung, the motor 14 first drives the screw rod 1101 to rotate together. When the screw rod 1101 rotates, the threaded block 1103 threadedly connected to the screw rod 1101 begins to move synchronously. When the threaded block 1103 moves, the rotating block 1104 rotatably connected to the threaded block 1103 begins to rotate around the rotation point of the threaded block 1103. When the rotating block 1104 starts to rotate, the height of the rotating block 1104 in the vertical direction will change, thereby pushing the receiving plate 1105 to rotate around the connecting block 1102. When the receiving plate 1105 starts to rotate, it will drive the nozzle 10 to rotate together.
