[0027] like Figure 1-Figure 7 As shown, the utility model provides a technical solution: a chlorinated paraffin dehydrochlorination device, comprising a shell 1, the inner bottom surface of the shell 1 is fixedly connected to a reaction barrel 2 and a reaction barrel 3, the top of the reaction barrel 2 is fixedly connected to an upper connecting pipe 20, the end of the upper connecting pipe 20 away from the reaction barrel 2 passes through the side wall of the reaction barrel 3, and is arranged on the inner bottom surface of the reaction barrel 3, the side wall of the reaction barrel 2 is fixedly connected to a lower connecting pipe 19, the end of the lower connecting pipe 19 away from the reaction barrel 2 is fixed to the side wall of the reaction barrel 3 The inner wall of the reaction barrel 2 is provided with a dechlorination device, which includes an air inlet pipe 4, an air outlet 5, a frame 6, a bracket 7, a liquid inlet pipe 8, an atomizing spray head 9, a straight spray hole 10, a spiral spray hole 11, a mounting rod 12, a demisting net 13, a guide ring 14, an annular partition 15, an annular baffle 16, an air bag 17, a drain pipe 18, a vertical rod 21, a demisting net 22, activated carbon 23, an annular partition 24, an annular baffle 25, an air bag 26, a discharge pipe 27, and an exhaust pipe 28.

[0028] In one embodiment of the utility model, the side wall of the reaction barrel 2 is sleeved with an air inlet pipe 4, and the air inlet pipe 4 is provided with an air outlet 5 on one side of the reaction barrel 2. The inner bottom surface of the reaction barrel 2 is fixedly connected with a frame 6, and the top end surface of the frame 6 abuts against the bottom end surface of the air inlet pipe 4. The inner wall of the reaction barrel 2 is fixedly connected with a bracket 7, and the bracket 7 is sleeved with a liquid inlet pipe 8. The liquid inlet pipe 8 is rotatably connected with an atomizing spray head 9. The inner bottom surface of the atomizing spray head 9 is provided with a straight spray hole 10, and the inner wall of the atomizing spray head 9 is provided with a spiral spray hole 11.

[0029] An annular partition 15 is fixedly connected to the inner top surface of the reaction barrel 2 with a mounting rod 12, a side wall of the mounting rod 12 is fixedly connected to a demisting net 13, an inner wall of the reaction barrel 2 is fixedly connected to a guide ring 14, an inner wall of the reaction barrel 2 is fixedly connected to an annular partition 15, the annular partition 15 is movably connected to an annular baffle 16, an air bag 17 is fixedly connected to the bottom surface of the annular baffle 16, a side wall of the reaction barrel 2 is fixedly connected to a drain pipe 18, the drain pipe 18 is arranged between the annular partition 15 and the guide ring 14, and the drain pipe 18 discharges the liquid collected above the guide ring 14.

[0030] The inner top surface of the reaction barrel 23 is fixedly connected with a vertical rod 21, the side wall of the vertical rod 21 is fixedly connected with activated carbon 23, the side wall of the vertical rod 21 is fixedly connected with a demisting net 22, the inner wall of the reaction barrel 23 is fixedly connected with a guide ring 14, the inner wall of the reaction barrel 23 is fixedly connected with an annular partition 15, the annular partition 15 is movably connected with an annular baffle 16, and the bottom surface of the annular baffle 16 is fixedly connected with an air bag 17.

[0031] The side wall of the second reaction barrel 3 is fixedly connected with a discharge pipe 27 , the top end surface of the second reaction barrel 3 is fixedly connected with an exhaust pipe 28 , and the activated carbon 23 is located at one end of the second demisting net 22 away from the upper connecting pipe 20 .

[0032] The waste gas with hydrogen chloride gas is introduced into the reaction barrel 2 through the air inlet pipe 4 and the air outlet hole 5, and the alkaline solution is atomized through the liquid inlet pipe 8 and the atomizing spray head 9, and then sprayed out from the straight spray hole 10. The pressure in the atomizing spray head 9 is relatively large, so that a part of the alkaline solution is sprayed out through the spiral spray hole 11. Since the spiral spray hole 11 is spirally arranged, the alkaline solution sprayed from this part of the spray hole causes a reaction force on the atomizing spray head 9, so that the atomizing spray head 9 rotates, and the alkaline solution can be evenly sprayed to a wider area, covering the space in the entire reaction barrel. The rotating atomizing spray head 9 can avoid the uncovered dead corner area left by the fixed spray head within the spraying range, ensure that the alkaline solution is evenly distributed in the entire reaction barrel, ensure that the hydrogen chloride gas in the waste gas can fully contact with the alkaline solution, and improve the gas-liquid contact efficiency.

[0033] The sprayed alkaline solution enters the inner bottom of the reaction barrel 23 through the lower connecting pipe 19, and the treated waste gas passes upward through the demisting net 13. The demisted waste gas enters the reaction barrel 23 through the upper connecting pipe 20 to react again, and the intercepted droplets are collected on the top of the guide ring 14. This part of the waste liquid will carry more residual hydrogen chloride. If it flows back into the dechlorination system, it will reduce the removal efficiency of the dechlorination system. When the waste liquid is collected to a certain extent, the waste liquid causes the air bag 17 and the annular baffle 16 to rise, and then open the gap between the annular partition 15 and the guide ring 14. At this time, the waste liquid is discharged through the drain pipe 18. The annular baffle 16 is set to prevent the waste gas from entering the drain pipe 18, so as to realize the classified treatment of waste liquid and waste gas, ensure that the waste liquid will not accumulate inside the system, and prevent blockage and liquid overflow.

[0034] In addition, the inner wall of the reaction barrel 2 is fixedly connected with an annular partition plate 24, which is movably connected with the annular baffle plate 25, and the bottom surface of the annular baffle plate 25 is fixedly connected with an air bag 26. Only when the alkaline solution on the inner bottom surface of the reaction barrel 2 is collected to a certain extent, the alkaline solution causes the air bag 26 and the annular baffle plate 25 to rise, thereby opening the gap between the annular partition plate 24 and the inner bottom surface of the reaction barrel 2. At this time, the alkaline solution can enter the reaction barrel 23 through the lower connecting pipe 19. The annular baffle plate 25 is set to avoid the passage of exhaust gas when the alkaline solution does not fill the inner bottom surface of the reaction barrel 23 in the early stage, thereby ensuring the normal operation of the multi-stage reaction, improving the purification effect of the exhaust gas, and ensuring that the discharged gas is more environmentally friendly and safe.

[0035] In the utility model, when in use, the exhaust gas is passed into the reaction barrel 2 through the air inlet pipe 4 and the air outlet 5, the alkaline solution is sprayed out through the straight spray hole 10, and a part of the alkaline solution is sprayed out through the spiral spray hole 11, so that the atomizing spray head 9 rotates, and the alkaline solution enters the inner bottom of the reaction barrel 3 through the lower connecting pipe 19, and the exhaust gas passes upward through the demisting net 13, passes through the upper connecting pipe 20 and enters the reaction barrel 3 to react again, and the intercepted droplets are collected on the top of the guide ring 14 and discharged from the drain pipe 18. Furthermore, after the alkaline solution on the bottom surface of the reaction barrel 2 is collected to a certain extent, the alkaline solution can enter the reaction barrel 3 through the lower connecting pipe 19.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
