Description

Automatic jetting device for adding ammonia

The utility model relates to a kind of water treatment device, and especially a kind of method with ammonification prevents oiler feed to metallic corrosion, prevents oxygen depolaxization corrosion and the ruined device of metal surface protection film.

At present, existing oiler feed ammonifying device adopts the ram pump ammonification, and all make with brass the Golan of valve base sealing up and down of pump, with in several days with regard to corrosion leakage, do not show ammonia, need frequent spare part, the maintenance cost height changed, and ammonia residual control difficulty, bigger to water ph value fluctuation, generally between 7-10, and pH value just can cause corrosion less than 8.6, make metal ion increase in the feedwater, cause fouling; PH value is greater than 9.2, and the steam ammonia content is too high in the therrmodynamic system, easily causes condenser copper tubes corrosion, makes water coolant enter therrmodynamic system and causes fouling, is directed at the boiler booster when serious, the steam turbine reduction of exerting oneself.

Ram pump ammonification failure rate height is regulated difficulty in sum, and the water quality qualification rate is low, leaks the health that seriously pollutes the harm people.

The purpose of this utility model provides a kind of safe, reliable, water quality qualification rate height, and can regulate the full-automatic injection ammonifying device of pH value in the water rapidly.

The purpose of this utility model is achieved in that

The utility model comprises conductivity apparatus, registering instrument, setter, topworks, it is characterized in that: ammonia-feeding pipe is connected with jet mixer through variable valve, jet mixer is connected with the pressure water inlet pipe simultaneously, the jet mixer outlet is connected with desalination jellyfish pipe through mixing liquid ammonia pipe, variable valve links to each other with topworks by link rod, on the desalination jellyfish pipe of ammonification place one segment distance, be provided with the conductivity apparatus electroplax, it links to each other with setter, topworks by lead through behind the conductivity apparatus again, and registering instrument links to each other with conductivity apparatus.

The utility model is squeezed into anion exchanger outlet or water tank and service pump import (drawing among the figure) with pressure water with the ammoniacal liquor for preparing and all can after injector mixes, adding a measuring point from ammonification point appropriate location, data are sent into instrument commander setter, amplifier amplifying signal indication topworks regulates, and the purpose that reaches adjustment makes pH value keep steady moving.The utility model level of automation height, ammonification is effective, has improved the qualification rate of water quality, and is safe and reliable.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a structure iron of the present utility model.

Fig. 2 is the structure iron of jet mixer.

See Fig. 1, ammonia-feeding pipe 10 is connected with jet mixer 11 through variable valve 9, jet mixer 11 is connected with pressure water inlet pipe 12 simultaneously, the outlet of jet mixer 11 is connected with desalination jellyfish pipe 1 through mixing liquid ammonia pipe 13, variable valve 9 is by link rod 8 and the 7(DKJ210 of topworks) link to each other, be provided with conductivity apparatus electroplax 2 on the desalination jellyfish of ammonification place one segment distance pipe 1, it is through conductivity apparatus 3(DDD-32B) after again through lead 6 and setter 4(DTL-321) thereby link to each other with topworks 7 and control topworks's 7 adjusting variable valve 9.

See Fig. 2, the mixing section 11.1 of jet mixer 11 is a Y-tube, its end has the joint 11.5 of through hole to be connected with the center, the front end of joint 11.5 connects a nozzle 11.2, the front end of nozzle 11.2 is positioned at mixing section 11.1, the outside surface of joint 11.5 is threaded with nut 11.7, the end of joint is fixed with flange 11.8,11.9, the front end of mixing section 11.1 is connected with a trunnion 11.3, the other end of trunnion 11.3 is connected with the end of a diffuser tube 11.4, the front end of diffuser tube 11.4 is connected with flange 11.12,11.13 the side opening of mixing section is connected with tail pipe 11.6, the other end of tail pipe is connected with flange 11.10,11.11.

All adopt screw-type to connect between each parts of jet mixer 11.

Be conical in the middle of the nozzle 11.2, two ends are cylindrical, and wherein end has outside screw, in the nozzle 11.2 round taper hole is arranged, and end aperture is greater than front end, and the front end in hole has one section to be cylindrical hole.

There is outside screw at diffuser tube 11.4 two ends, are round taper hole in the diffuser tube, and the front end aperture is greater than end, and the end in hole has one section to be cylindrical hole.

Because in nozzle 11.2 and the diffuser tube 11.4 is round taper hole, (relative round taper hole) can be regulated liquid pressure and make the liquid thorough mixing, and flows into desalination jellyfish pipe 1.

Water enters from the end of jet mixer 11, and ammoniacal liquor enters from the side opening of jet mixer 11, and the front end outflow from jet mixer 11 after mixing in mixing section 1 enters desalination jellyfish pipe 1.
