[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The department negative pressure pipeline 9 is connected to the mercury collector 1, the mercury collector 1 is connected to the dirt separator 2, the dirt separator 2 tank is connected to the tank cleaning and disinfection liquid 14, the lower end sewage outlet is connected to the central sewage treatment, and the dirt separator 2 is connected to the bacterial filter. Filter 3, the bacterial filter 3 is connected to the manual ball valve 13 to the wet negative pressure pump group 6 through the negative pressure pump group suction line 10, the wet negative pressure pump group 6 is connected to the check valve to the liquid circulation system 5, the liquid circulation system 5 is connected to the gas emission disinfection system 4 through the negative pressure pump group exhaust line 11, the gas emission disinfection system 4 is connected to the outdoors, the bacterial filter 3 is also divided into a pipe connecting the manual ball valve 13 and the check valve 12 to the dry negative pressure pump group 7 through the negative pressure pump group suction line 10, the dry negative pressure pump group 7 is connected to the gas emission disinfection system 4 through the negative pressure pump group exhaust line 11, and the electric control box 8 is connected to the wet negative pressure pump group 6 and the dry negative pressure pump group 7 for power supply.

[0013] During use, the user sets the required negative pressure value in the electric control box 8. The dry-wet negative pressure generator uses a variable frequency drive method to first drive the wet negative pressure pump group 6 through variable frequency speed regulation and then monitor the real-time pressure through the negative pressure pipeline pressure sensor of the unit. If the pressure value is reached, the motor balances the speed to balance the negative pressure value set by the user. If the wet negative pressure pump group 6 cannot reach the negative pressure value set by the user and has reached the limit of the wet negative pressure pump group 6, the dry negative pressure pump group 7 is started from small to large through variable frequency to pressurize the pipeline, so as to reach the negative pressure value set by the user, and then control the speed to keep the pressure of the pipeline constant. Principle of pipeline connection: Oral medical sewage enters the silver-mercury collector 1 from the strong and weak suction negative pressure pipeline 9 of the comprehensive treatment table of the department to filter mercury and solid medical waste impurities, and then goes to the sewage separator 2 to separate the medical sewage and medical waste gas. The water will flow to the bottom of the tank through the maze gravity, and then be discharged to the central sewage pool through the separation pump of the sewage separator. The tank will be regularly sprayed with cleaning disinfectant 14 for sterilization; the medical waste gas will continue to be sucked into the bacterial filter 3 due to suction for sterilization, and then pass through the dry-wet negative pressure pump group and the liquid circulation system 5 to the gas discharge disinfection system 4 for disinfection and then be discharged outdoors. The advantages of the wet negative pressure pump group 6 and the dry negative pressure pump group 7 are combined with each other to make up for each other's shortcomings. The wet negative pressure pump group 6 plays a leading role in the entire negative pressure system, providing a leading role in generating negative pressure by vacuuming, and the dry negative pressure pump group 7 plays an auxiliary role. The dry negative pressure pump group 7 mainly provides large-flow suction for the negative pressure pipeline, which solves the problems of high energy consumption, high noise, insufficient vacuum and insufficient flow in the traditional dry-wet suction negative pressure system, thereby reducing the requirements for the thickness of the negative pressure vacuum pipeline, easy heat generation, and easy burning of the motor when the load is large. It also solves many problems such as water and air mixing together when the wet suction negative pressure system is discharged.
