[0002] Fluorogypsum is a by-product of producing hydrogen fluoride from sulfuric acid and fluorspar. Its main component is anhydrous calcium sulfate. It mainly comes from industrial production processes and is highly corrosive and toxic. Therefore, it is considered a hazardous waste. When treating industrial solid waste fluorogypsum, a low-temperature decomposition device is required.

[0003] When the industrial solid waste fluorine gypsum low-temperature decomposition device treats industrial solid waste fluorine gypsum, waste gas will be generated. In order to maintain a certain internal temperature, the device needs to discharge the internal low-temperature gas and introduce new hot gas. At this time, the waste gas and some dust will also be discharged together. However, the traditional industrial solid waste fluorine gypsum low-temperature decomposition device cannot treat the waste gas and some of the discharged dust well, causing the waste gas and some dust to be directly dissipated into the air, which will directly affect the overall treatment effect of the device on industrial solid waste fluorine gypsum.

The top of one side of the low-temperature decomposition box 1 is connected with a butt pipe 2 for hot gas to enter, and a fixed bracket 5 is fixed on the other side of the low-temperature decomposition box 1. A top frame 22 is fixed on the fixed bracket 5. The top of the low-temperature decomposition box 1 is connected with a feed pipe and an outlet pipe 3 in the left and right directions respectively, and a solenoid valve 4 is provided at one end of the outlet pipe 3. Both sides of the bottom of the low-temperature decomposition box 1 are connected with a discharge pipe, and auxiliary valves are provided on the discharge pipe and the feed pipe. An auxiliary cleaning component for use with the outlet pipe 3 is provided on the fixed bracket 5, and the auxiliary cleaning component includes a rotatable valve mounted on the top of the fixed bracket 5. The front and back sides of the fixed shaft 11, the fixed shaft 11 is fixed with a circular box 10 at one end close to each other, and the other end of the air outlet pipe 3 is connected to one side of the circular box 10, and the circular box 10 is embedded with a filter 18. The left side of the bottom of the circular box 10 is connected to a collection box 17, and the collection box 17 is located on one side of the filter 18. A placement box 6 is fixed to the bottom of the fixed bracket 5, and the bottom of the placement box 6 away from the low-temperature decomposition box 1 is connected to a bend 8. One end of the bend 8 is connected to the other side of the circular box 10, and an air outlet 7 is provided on the top of the placement box 6 away from the low-temperature decomposition box 1. A venturi tube 9 is provided on the bend 8. The design of the venturi tube 9 can accelerate the discharged gas and improve the treatment efficiency of the discharged gas;

[0021] Reference Figure 1The front of the fixed bracket 5 is fixed with an electric slide rail slide 15 through an extension frame, and a pushing seat 16 is provided on the electric slide rail slide 15. A support frame located at the bottom of the venturi tube 9 is fixed on the bent pipe 8, and one end of the support seat is fixed on the fixed bracket 5. The design of the support frame improves the overall stability of the bent pipe 8 to prevent it from breaking. A positioning frame 14 is fixed on the top of one side of the fixed bracket 5, and a spring 13 is fixed on the positioning frame 14, and one end of the spring 13 is fixed on the fixed bracket 5. One set of fixed shafts 11 is fixed with a vertical plate 12 used in conjunction with the pushing seat 16. There is a gap between the vertical plate 12 and the electric slide rail slide 15. The design of the gap allows the vertical plate 12 to swing stably without obstruction. The ends of the outlet pipe 3 and the bent pipe 8 that are close to each other are both telescopic tube structures. A first one-way valve is provided at the end of the bent pipe 8 close to the placement box 6. By setting an auxiliary cleaning component and using the filter 18, dust in the exhaust gas can be isolated to prevent dust from being directly discharged to the outside. The vibration force can effectively prevent dust from directly adhering to the filter 18, and the dust shaken off can be collected. At the same time, the harmful substances in the exhaust gas can be neutralized, and the exhaust gas can be cooled synchronously to prevent the harmful substances in the gas from being directly discharged and affecting the surrounding environment, thereby improving the treatment effect of the device on industrial solid waste fluorine gypsum. A plurality of groups of horizontal pipes 21 are evenly embedded on the other side of the circular box 10. An annular pipe 19 is fixed to the end of the multiple groups of horizontal pipes 21 away from the circular box 10. The annular pipe 19 is connected to the inflation pipe 20 and the top of the inflation pipe 20 is fixed to the top frame 22. The end of the inflation pipe 20 close to the annular pipe 19 is a telescopic pipe structure, and the end of the inflation pipe 20 away from the annular pipe 19 is provided with a second one-way valve. By arranging the horizontal pipe 21, the annular pipe 19 and the inflation pipe 20, the inflation pipe 20 can be connected to the external inflation equipment, and the gas can be used to counter-impact the filter 18, so as to improve the cleaning effect of the filter 18 and further improve the anti-clogging effect of the filter 18.

[0022] In the present invention, when the industrial solid waste fluorinated gypsum is decomposed in the low-temperature decomposition box 1, certain harmful gases will be generated, and as the device is continuously running, the internal gas needs to be replaced so that the temperature inside the device can be maintained at a suitable level. At this time, the user opens the solenoid valve 4 through the controller to release the locking state of the air outlet pipe 3. At this time, the exhaust gas containing dust and harmful substances will be transported to the circular box 10 through the air outlet pipe 3, and the filter 18 will filter the dust discharged therefrom to prevent the dust from being directly discharged to the outside. At the same time, the user opens the electric slide seat 15 through the controller and presets the reciprocating stroke of the electric slide seat 15, thereby driving the push seat 16 to move back and forth. At the same time, the spring 13 can give the vertical plate 12 a certain supporting force and rebound force. At this time, the push seat 16 is used to push the vertical plate 12. 16 can reciprocate and impact the vertical plate 12, so that the circular box 10 and the filter screen 18 continuously generate vibration force, which can effectively prevent dust from directly adhering to the filter screen 18 and prevent the filter screen 18 from being blocked. At this time, the dust shaken off will enter the collection box 17 for collection under the driving of the swing force, and the gas will quickly enter the placement box 6 through the bend 8 under the acceleration of the venturi tube 9 after filtering. At the same time, the first one-way valve can effectively prevent the liquid in the placement box 6 from entering the bend 8. At this time, the bend 8 can directly pass the exhausted gas into the alkaline solution in the placement box 6 to neutralize the harmful acidic substances in the exhausted gas, and can simultaneously cool the exhausted gas to prevent the harmful substances in the gas from being directly discharged and affecting the surrounding environment, and improve the treatment effect of the device on industrial solid waste fluorine gypsum.
