Abstract
Description
Technical Field

[0016] Working principle:
[0017] ① Drug delivery: the drug liquid metering pump 16 delivers the drug liquid to the honeycomb drug-shooting device composed of the honeycomb cylindrical inner tube (9) and the stainless steel conical tube 10 through the stainless steel drug liquid pipeline. The drug liquid delivery pipeline is respectively installed with a stainless steel manual stop valve 6 and a one-way valve 3 according to the water flow direction. The back-blowing pipe 4 is connected to a compressed air pipeline 5, and the compressed air pipeline 5 is connected to an air compression pump (17) to facilitate the control of drug liquid delivery. ② Diffusion and mixing: under the pressure of the drug liquid metering pump 16, the drug liquid enters the honeycomb inner tube of the drug-shooting device. Generally, the pump pressure of the drug liquid metering pump is 0.4-0.6 MPa. In order to facilitate diffusion, the drug liquid flow direction is consistent with the raw water flow direction (the raw water flow rate is usually 1.2-2 m / s). At the same time, the air compression pump 17 is turned on (the pressure is controlled at 0.35-0.5 MPa). Under the action of the water head pressure and the strong purge of the compressed air, the drug liquid quickly escapes and diffuses around through the circular hole in the honeycomb cylindrical inner tube 9. The liquid medicine particles that come out are fully mixed with the raw water flowing in the mixer and carried away, forming floccules and precipitates in the back-end processing equipment; ③ Back-blowing cleaning: In order to prevent the floccules and particles formed by the liquid medicine and raw water from clogging the honeycomb holes and the pipe section between the mixer and the honeycomb cylindrical inner tube 9 after parking, open the manual stop valve 6 and compress the air for back-blowing cleaning.
