[0015] A method for using a hydrogen fluoride wastewater treatment production device comprises the following steps:

[0016] Step 1, introducing the hydrogen fluoride wastewater into the liquid guide tube through the liquid inlet pipes on both sides, and introducing it into the liquid storage bin at the top position through a plurality of mutually connected liquid drainage grooves and the liquid guide groove at the top position, and automatically feeding the hydrogen fluoride wastewater. Since the hydrogen fluoride wastewater is introduced into the processing outer frame, the hydrogen fluoride wastewater in the processing outer frame can be sealed to prevent the hydrogen fluoride wastewater in the processing outer frame from overflowing and polluting the environment during the treatment;

[0017] Subsequently, an appropriate amount of lime (calcium hydroxide) or other calcium salt is introduced into the liquid storage bin at the top of the treatment outer frame through the feed inclined pipe, so that the fluoride ions in the hydrogen fluoride wastewater are combined with the calcium ions;

[0018] Step 2: After adding an appropriate amount of lime (calcium hydroxide) or other calcium salt to the liquid storage bin at the top position, the first motor is controlled to start again to drive the second conical gear to drive the first conical gear and the driving tube to rotate, thereby controlling the rotation of multiple isolation plates, rotating the next empty liquid storage bin to the top position, and the liquid storage bin into which the hydrogen fluoride wastewater and an appropriate amount of lime (calcium hydroxide) or other calcium salt are introduced is gradually rotated from a side position away from the liquid discharge frame to a side position of the liquid discharge frame, and at the same time continues to be introduced into the liquid guide tube through the liquid inlet pipes on both sides, and through The multiple interconnected drainage grooves and the liquid guide grooves at the top position are led into the liquid storage bin at the top position, and the hydrogen fluoride wastewater is automatically fed, and an appropriate amount of lime (calcium hydroxide) or other calcium salts are continuously introduced into the liquid storage bin at the top position of the treatment outer frame through the feeding inclined tube, so that the fluoride ions in the hydrogen fluoride wastewater are combined with the calcium ions. While the liquid storage bin is rotated, the fluoride ions in the hydrogen fluoride wastewater react and combine with the calcium ions to form insoluble calcium fluoride precipitation, thereby effectively treating the hydrogen fluoride wastewater and preventing the hydrogen fluoride wastewater from polluting the environment;

[0019] Until the transmission and drainage frame is located, the reacted liquid is filtered and discharged through the filter plate, and the calcium fluoride precipitate is retained in the corresponding liquid storage bin, and the liquid storage bin continues to rotate until the calcium fluoride precipitate rotates to the storage tank position;

[0020] During the process, the hydrogen fluoride wastewater introduced into the outer frame will overflow the hydrogen fluoride gas, and the hydrogen fluoride gas is introduced into the top position of the refueling inner cylinder through the gas guide frame, the gas guide inner groove at the top position of the gas guide middle frame, the gas guide outer groove and the air inlet perforation. The adsorbent adsorbs the hydrogen fluoride gas to further prevent the hydrogen fluoride gas from overflowing the environment and causing environmental pollution. After the adsorption treatment, the gas is evenly discharged into the exhaust main frame through multiple exhaust perforations, and then automatically discharged through the exhaust main frame;

[0021] Step 3: Control the second motor to start and drive the corresponding translation screw to rotate, thereby controlling the cleaning scraper to move, the cleaning scraper is separated from one side of the storage tank and slides in the corresponding liquid storage bin, the cleaning scraper pushes the calcium fluoride precipitate retained in the liquid storage bin to the position of the storage tank on the other side, and discharges it through the waste discharge frame and waste discharge pipe on the other side, so as to automatically discharge the calcium fluoride precipitate;

[0022] Step 4: When the adsorbent in the top position of the refueling inner cylinder needs to be replaced after adsorbing and treating the hydrogen fluoride gas for a period of time, the third motor is controlled to start driving the fourth conical gear to drive the third conical gear and the flip horizontal axis to rotate, and then the refueling inner cylinder is controlled to rotate and flip, and the empty storage bin at the lower position is flipped to the upper position. At the same time, the top position agent guide groove corresponds to the position of the agent inlet elbow, and the bottom position agent guide groove corresponds to the position of the agent outlet elbow. The first valve is controlled to open, and the new adsorbent is introduced into the top position storage bin through the agent inlet elbow and the corresponding position agent guide groove, and the hydrogen fluoride gas is continued to be adsorbed and treated, and the adsorbent is effectively replaced. At the same time, the second valve is opened, and the waste adsorbent in the bottom position storage bin is directly discharged through the agent outlet elbow under the action of the aggregation frame, so that the waste adsorbent is automatically discharged, which is convenient for the subsequent continued use of the empty storage bin.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. By setting up the treatment device, the hydrogen fluoride wastewater in the treatment outer frame can be sealed to prevent the overflow of hydrogen fluoride gas from polluting the environment during the treatment of the hydrogen fluoride wastewater in the treatment outer frame, and the hydrogen fluoride wastewater can be effectively treated to prevent the hydrogen fluoride wastewater from polluting the environment, and it is convenient to automatically discharge and clean up the calcium fluoride precipitation.

[0025] 2. By setting up a gas treatment device, the hydrogen fluoride gas overflowing from the hydrogen fluoride wastewater is adsorbed and treated, further preventing the hydrogen fluoride gas from overflowing the environment and causing environmental pollution, and facilitating the effective replacement of the adsorbent and the automatic discharge of the waste adsorbent.

[0051] A method for using a hydrogen fluoride wastewater treatment production device comprises the following steps:

[0052] Step 1: introducing the hydrogen fluoride wastewater into the liquid guide tube 24 through the liquid inlet pipes 242 on both sides, and introducing it into the liquid storage bin at the top position through the multiple liquid drainage grooves 241 that are interconnected and the liquid guide groove 221 at the top position, so as to automatically feed the hydrogen fluoride wastewater. Since the hydrogen fluoride wastewater is introduced into the processing outer frame 21, the hydrogen fluoride wastewater in the processing outer frame 21 can be sealed to prevent the hydrogen fluoride wastewater in the processing outer frame 21 from overflowing and polluting the environment during the treatment;

[0053] Subsequently, an appropriate amount of lime (calcium hydroxide) or other calcium salt is introduced into the liquid storage bin at the top of the treatment outer frame 21 through the feed inclined pipe 31, so that the fluoride ions in the hydrogen fluoride wastewater are combined with the calcium ions;

[0054] Step 2: After adding an appropriate amount of lime (calcium hydroxide) or other calcium salt to the liquid storage bin at the top position, the first motor 223 is controlled to start again to drive the second conical gear 224 to drive the first conical gear 222 and the driving tube 22 to rotate, thereby controlling the rotation of the plurality of isolation plates 23, rotating the next empty liquid storage bin to the top position, and the liquid storage bin into which the hydrogen fluoride wastewater and an appropriate amount of lime (calcium hydroxide) or other calcium salt are introduced is gradually rotated from a side position away from the liquid discharge frame 211 to a side position of the liquid discharge frame 211, and at the same time, the liquid guide tube is continuously introduced through the liquid inlet pipes 242 on both sides. 24, and introduce the liquid into the liquid storage bin at the top through the interconnected multiple drainage grooves 241 and the liquid guide groove 221 at the top, continue to automatically feed the hydrogen fluoride wastewater, and continue to introduce an appropriate amount of lime (calcium hydroxide) or other calcium salts into the liquid storage bin at the top of the treatment outer frame 21 through the feeding inclined pipe 31, so that the fluoride ions in the hydrogen fluoride wastewater are combined with the calcium ions. While the liquid storage bin is rotated, the fluoride ions in the hydrogen fluoride wastewater react and combine with the calcium ions to form insoluble calcium fluoride precipitation, thereby effectively treating the hydrogen fluoride wastewater and preventing the hydrogen fluoride wastewater from polluting the environment;

[0055] Until the transmission and drainage frame 211 is located, the reacted liquid is filtered and discharged through the filter plate 212, and the calcium fluoride precipitate is retained in the corresponding liquid storage bin, and the liquid storage bin continues to rotate until the calcium fluoride precipitate rotates to the storage tank 201;

The adsorbent adsorbs the hydrogen fluoride gas to further prevent the hydrogen fluoride gas from overflowing the environment and causing environmental pollution. After the adsorption treatment, the gas is evenly discharged from the exhaust main frame 421 through multiple exhaust perforations 404, and then automatically discharged through the exhaust main frame 421;

[0057] Step 3: Control the second motor 262 to start and drive the corresponding translation screw 261 to rotate, thereby controlling the cleaning scraper 26 to move. The cleaning scraper 26 is separated from one side of the storage tank 201 and slides in the corresponding liquid storage bin. The cleaning scraper 26 pushes the calcium fluoride precipitate retained in the liquid storage bin to the position of the other side storage tank 201, and discharges it through the waste discharge frame 251 and the waste discharge pipe 252 on the other side, so as to automatically discharge the calcium fluoride precipitate.

[0058] Step 4: When the adsorbent in the top position of the refueling inner cylinder 44 needs to be replaced after adsorbing and treating the hydrogen fluoride gas for a period of time, the third motor 452 is controlled to start driving the fourth conical gear 453 to drive the third conical gear 451 and the flip horizontal axis 45 to rotate, and then the refueling inner cylinder 44 is controlled to rotate and flip, and the empty storage bin at the lower position is flipped to the upper position. At the same time, the top position guide groove 405 corresponds to the position of the inlet elbow 46, and the bottom position guide groove 405 corresponds to the position of the outlet elbow 47. The first valve 461 is controlled to open, and the new adsorbent is introduced into the top position storage bin through the inlet elbow 46 and the corresponding position guide groove 405, and the hydrogen fluoride gas is continued to be adsorbed and treated, and the adsorbent is effectively replaced. At the same time, the second valve 471 is opened, and the waste adsorbent in the bottom position storage bin is directly discharged through the outlet elbow 47 under the action of the gathering frame 443, so that the waste adsorbent is automatically discharged, which is convenient for the subsequent continued use of the empty storage bin.
