[0023] Specifically, four supporting legs 101 are fixedly welded at the bottom of the production bin 1 to provide support for the production bin 1, a feed pipe 102 penetrating the top plate of the production bin 1 is fixedly welded at the top of the production bin 1 to allow materials to enter the production bin 1, a discharge pipe 103 is fixedly welded at the bottom of the production bin 1 to allow materials to flow out of the production bin 1, a pressure reducing pipe 3 and a pressure increasing pipe 4 penetrating the top plate of the production bin 1 are fixedly welded at the top of the production bin 1, and a vacuum pump 301 is fixedly installed on the pressure reducing pipe 3 to enable the vacuum pump 301 to extract the gas in the production bin 1, thereby making the production The air pressure in the production warehouse 1 becomes smaller, so that the conditions in the production warehouse 1 meet the production requirements of polyferric sulfate. A control valve 401 is fixedly installed on the boosting pipe 4, and the other end of the pressure reducing pipe 3 and the boosting pipe 4 is fixedly connected to the processing warehouse 2, so that when the valve 6 on the pressure reducing pipe 3 and the control valve 401 on the boosting pipe 4 are closed, the production warehouse 1 can maintain a negative pressure state. However, since the raw materials in the production warehouse 1 will produce harmful gases containing polyferric sulfate during production, the pressure in the production warehouse 1 increases. At this time, the valve 6 on the pressure reducing pipe 3 can be opened, and the vacuum pump 301 can be started to remove the gas from the production warehouse 1. The gas in the processing chamber 2 is sucked into the processing chamber 2 by the chamber 1 to reduce the pressure in the production chamber 1. When the pressure in the production chamber 1 is too low, the control valve 401 can be opened to allow the gas in the processing chamber 2 to enter the production chamber 1 to increase the pressure in the production chamber 1. A motor 5 is fixedly installed on the processing chamber 2, and a blower 501 is fixedly welded on the output shaft of the motor 5. A baffle plate 204 and a guide plate 205 are fixedly welded on the inner wall of the processing chamber 2. The blower 501 is rotatably connected to the air supply hole on the baffle plate 204, so that the harmful gas entering the processing chamber 2 can be blown out through the rotation of the blower 501. When it reaches the bottom of the baffle plate 204, a water inlet pipe 201 is fixedly welded on the side of the processing chamber 2, and a water pump 202 is fixedly installed on the water inlet pipe 201, so that the water pump 202 can control the water to enter the processing chamber 2, so that the water gathers at the bottom of the processing chamber 2. When the harmful gas reaches below the baffle plate 204, the polyferric sulfate in the gas will dissolve in the water due to its highly soluble in water property. A water outlet pipe 203 is fixedly connected to the bottom of the processing chamber 2, so that the water in the processing chamber 2 can finally be collected and processed, thereby avoiding the leakage of harmful gases and reducing the impact on human body and the environment.

[0024] The working principle and use process of the utility model are as follows: first, the raw materials for producing polyferric sulfate are put into the production warehouse 1 through the feed pipe 102, then the valve 6 on the pressure reducing pipe 3 is opened, and the vacuum pump 301 is started to suck the gas in the production warehouse 1 and the harmful gas generated by the production into the processing warehouse 2 through the pressure reducing pipe 3, so that the environment in the production warehouse 1 is in a negative pressure environment. When the air pressure in the production warehouse 1 is too low, the control valve 401 can be opened to allow the gas in the processing warehouse 2 to enter the production warehouse 1, thereby increasing the pressure in the production warehouse 1. When the harmful gas in the production warehouse 1 reaches the processing warehouse 2, the pressure in the processing warehouse 2 is increased. When in the processing bin 2, start the motor 5 and control the blower 501 to rotate so that the harmful gas is sucked under the baffle plate 204, and then start the water pump 202 to suck water into the bottom of the processing bin 2 through the water inlet pipe 201. At this time, the polyferric sulfate in the gas will dissolve in the water due to its highly soluble in water. Finally, open the valve 6 on the outlet pipe 203, and the water will flow along the guide plate 205 through the outlet pipe 203 to the outside of the processing bin 2, which is convenient for the staff to collect and process it, avoid the leakage of harmful gases, and reduce the impact on the human body and the environment.
