When the non-condensable gas pipeline is tempered and deflagrated, explosion venting gas enters an air inlet pipe 3502 of a front water seal box 3501 of the closed safety water tank 35, the distance between the lower edge of the air inlet pipe 3502 and the water surface in the front water seal box 3501 is 100mm, when the pressure of the explosion venting gas is greater than 1000pa, the explosion venting gas passes through the water body in the front water seal box 3501 and enters the front water seal box 3501 and a communicating U-shaped pipe 3504, because the other end of the communicating U-shaped pipe 3504 is inserted into the water surface 100mm below a rear water air box 3503, the pressure of the explosion venting gas after entering the front water seal box 3501 is reduced, the water seal resistance of the rear water air box 3504 cannot be overcome, because the communicating gas outlet 3505 is connected with a high-temperature flue gas inlet 3101 of the gas high-temperature pyrolysis furnace 31, the communicating U-shaped pipe 3505 is under the action of a flue gas draught fan 36, the explosion venting gas enters the gas high-temperature pyrolysis furnace 31 under the action of negative pressure, and is discharged from a chimney 37 together with the flue gas after the decomposition treatment of the gas high temperature pyrolysis furnace 31. If the closed safety water tank 35 encounters the situation that the pressure of explosion venting gas is large and the quantity is large, a part of the explosion venting gas can instantly pass through the water body of the rear water seal tank 3504 and is vented out from the gas vent port 3506 at the top of the rear water seal tank 3504, when the pressure is reduced after the gas is vented out, the subsequent gas is blocked by the water level of the rear water seal tank 3504, cannot be continuously vented out from the gas vent port 3506 at the top of the rear water seal tank 3504, and can only be discharged to the gas high-temperature pyrolysis furnace 31 from the gas outlet port 3505 of the communicated pipe. The closed safety water tank 35 avoids that a large amount of combustible gas is discharged into a workshop when the conventional safety water tank is exploded, so that the air in the workshop is polluted and potential safety hazards are caused.

The content of hydrogen in the dry distillation gas generated by decomposing the resin in the waste blades in the dry distillation process is very high, the hydrogen is flammable and explosive gas, and tempering is easily generated in the recycling process, so that the pipeline between the condensation separator 28 and the dry distillation gas exhaust blower 30 is connected with the air inlet of the closed safety water tank 35 through a tee joint, and the high-temperature chamber 3, the condensation separator 28 and the like are prevented from being damaged when the non-condensable gas pipeline is subjected to tempering and explosion.

2) The operation temperature in the dry distillation chamber 2 is set to be 650-700 ℃ through a control system, and the operation temperature is kept for 2-3 hours (adjusted according to the pyrolysis condition of the waste blades) after reaching the operation temperature. The highest temperature set by the dry distillation chamber 2 is less than or equal to 900 ℃, the control system automatically alarms when the temperature exceeds 900 ℃, and simultaneously all the natural gas burners 4 of the high-temperature chamber 3 stop operating. The pressure in the high-temperature chamber 3, the dry distillation chamber 2 and the high-temperature pyrolysis furnace 31 set by the control system is-20 pa to-40 pa, so that the waste blade dry distillation system can keep economical and stable operation, and the waste gas in the dry distillation chamber 2 is prevented from overflowing to pollute the air environment of a workshop. The operation temperature of the gas high-temperature pyrolysis furnace set by the control system is 700-800 ℃, so that the peculiar smell in the dry distillation gas is completely pyrolyzed, and the pollution of the discharged peculiar smell to the surrounding environment is avoided. And when the set highest temperature in the gas high-temperature pyrolysis furnace is less than or equal to 900 ℃, the control system gives an alarm when the temperature exceeds 900 ℃, and the natural gas burner is automatically stopped 3102. The water temperature in the softened water tank 22 is set to be 20-60 ℃. In the process of circularly cooling the condensation separator 28, when the water temperature of the softened water tank 22 is higher than or equal to 60 ℃, the control system starts the cooling tower 23 and the cooling tower circulating pump 2301 to reduce the water temperature in the softened water tank 22, so that the water temperature of the softened water tank 22 is controlled between 20 ℃ and 60 ℃.

3) After the temperature and the pressure of each device are set by the control system, the liquid levels of the waste heat boiler 32, the closed safety water tank 28 and the heat storage tank 33 are checked, water is supplemented if necessary, the preparation states of various devices, sensors and the like are checked and observed, under the condition that all the devices are in a normal state, the control system starts the gas purification treatment device in sequence, firstly, the flue gas induced draft fan A36 is started, then, the dry distillation gas exhaust blower 30, the pyrolysis liquid reflux pump 2503, the condenser cooling water pump 2202, the fresh air unit 48 and the exhaust fan 50 are started, and after the devices are operated normally, the current and the rotating speed of the fans and the water pumps are checked, and the pressure and the flow of the pyrolysis liquid and the cooling water are checked. And checking the pressure conditions in the high-temperature chamber, the dry distillation chamber, the high-temperature pyrolysis furnace and the like.

5) Under the condition that all equipment and data are in a normal state, a natural gas burner 4 and a non-condensable gas burner 5 of the high-temperature chamber 3 are started, a natural gas burner 3102 of the gas high-temperature pyrolysis furnace 31 is started, and the temperature and pressure conditions in the high-temperature chamber 3, the dry distillation chamber 2, the gas high-temperature pyrolysis furnace 31 and the waste heat boiler 32 and the operation conditions of various instruments and equipment are observed.

6) During the waste blade dry distillation process, as the temperature in the dry distillation chamber 2 rises, the resin in the blades starts to decompose, and dry distillation gas generated during the decomposition enters the spray tank 26 from the dry distillation gas outlet 14 of the dry distillation chamber 2 under the action of the dry distillation gas exhaust blower 30. The pyrolysis liquid sprayed from the spray tank 26 (nozzle) carries dust in the dry distillation gas down, and the pyrolysis liquid flows into the spray tower 27 from the outlet of the spray tank 26 together with the dry distillation gas. The spraying of the pyrolysis liquid in the spray tank 26 is to prevent the pipeline between the outlet 14 of the dry distillation gas of the dry distillation chamber 2 and the inlet of the spray tower 27 from being blocked by dust and tar. The dry distillation gas enters a spray tower 27 and then is subjected to spray dust removal and temperature reduction treatment, and the treated gas enters a condensation separator 28. The pyrolysis liquid sprayed in the spray tower 27 is discharged from the pyrolysis liquid port 2704 at the bottom of the spray tower 27 and flows into the pyrolysis liquid storage tank 25. The spray tower 27 uses pyrolysis liquid spray instead of conventional water spray, not only to avoid generating a large amount of wastewater difficult to treat, but also to recover tar and the like with economic value generated after the resin in the waste blade is pyrolyzed.

The gas treated by the spray tower 27 enters the condensation separator 28, and the dry distillation gas passes through the gap between the cooling pipes 2807 from the upper spray chamber 2810 of the condenser 28 to the lower hot electrolyte collection chamber 2806, returns to the upper spray chamber 2810 from the lower hot electrolyte collection chamber 2806, returns to the lower hot electrolyte collection chamber 2806 from the upper spray chamber 2810, returns to the upper spray chamber 2810 from the lower hot electrolyte collection chamber 2806, and is discharged from the gas outlet 2802 to enter the demister 29. The dry distillation gas is turned back, sprayed and cooled for many times, so that the temperature of the dry distillation gas is reduced, tar and carbon powder generated by resin pyrolysis in waste blades are sprayed and condensed, and non-condensable combustible gas is separated out. The non-condensable combustible gas is conveyed to a non-condensable gas burner 5 of the high-temperature chamber 3 by the dry distillation gas exhaust blower 30, on one hand, a heat source is provided for the high-temperature chamber 3 through the combustion of combustible components in the non-condensable combustible gas, and on the other hand, the peculiar smell in the non-condensable combustible gas is pyrolyzed and eliminated through the high temperature in the high-temperature chamber 3. The pyrolysis liquid sprayed in the condensation separator 28 flows into the pyrolysis liquid storage tank 25 after being discharged from the pyrolysis liquid port 2808.

The cooling pipes 2807 are sprayed with the pyrolysis liquid in the condensation separator 28, so that firstly, the dust in the pyrolysis liquid can be prevented from blocking gaps between the cooling pipes 2807; secondly, the dust in the non-condensable gas can be further reduced, the pollutants in the flue gas when the non-condensable gas is combusted in the high-temperature chamber 3 are reduced, and the flue gas is ensured to reach the national standard; thirdly, the surface of the cooling pipe 2807 is used for cooling the pyrolysis liquid, and the heat in the pyrolysis liquid is transferred into cooling water, so that the over-high temperature of the pyrolysis liquid in the pyrolysis liquid storage tank 25 is avoided.

7) When the waste blades in the dry distillation chamber 2 finish the dry distillation process, the control system stops the operation of the natural gas burner 4 of the high-temperature chamber 3, all equipment of the gas treatment system keeps operating, a valve of a steam outlet 3302 of the heat storage tank 33 is gradually opened to fill steam into the dry distillation chamber 2, so that the temperature in the dry distillation chamber 2 is reduced at the rate of 20-30 ℃ per minute, the steam filled into the dry distillation chamber 2 can reduce the temperature of the dry distillation chamber 2, harmful gas in the dry distillation chamber 2 is removed at the same time, the proportion of combustible components in the gas in the dry distillation chamber 2 is reduced, negative pressure is kept in the dry distillation chamber when the steam is filled into the dry distillation chamber 2, and dry distillation gas is prevented from entering a workshop when the heat insulation sealing door 18 is opened. When the temperature in the dry distillation chamber 2 is reduced to be below 100 ℃, the control system starts an actuator 2101 of a heat insulation sealing door locker 21, after the heat insulation sealing door locker 21 is completely loosened, a driving platform 20 is started to open the heat insulation sealing door 18 by 100-200 mm, and under the action of negative pressure in the dry distillation chamber 2, air in a workshop enters the dry distillation chamber 2, so that the temperature of the dry distillation chamber 2 is continuously reduced. When the temperature in the dry distillation chamber 2 is reduced to below 30 ℃, the control system starts the driving platform 20 to pull the movable groove type dry distillation bed 1 into the feeding and discharging workshop 60.
