Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b): the novel water reducing agent spray dryer of the embodiment is shown in fig. 1-3, and comprises a cylindrical tank body 1, a circular truncated cone-shaped boss 101 is arranged at the top of the tank body 1, a suction cup 8 is arranged at the top inside the boss 101, the suction cup 8 is externally connected with an exhaust fan 7, an air outlet of the exhaust fan 7 is connected with a dryer 9, a peristaltic pump 2 is arranged at the top of the tank body 1, a feed inlet of the peristaltic pump 2 is connected with a liquid guide pipe 5, the bottom of the liquid guide pipe 5 is connected with a liquid feed box 19, a discharge port of the peristaltic pump 2 is connected with a plurality of nozzles 4, an air compressor 3 is fixed at the top of the tank body 1, the air compressor 3 is also connected with the nozzles 4 through an air pipe 6, an air guide bin 12 is arranged at the upper end of the inner wall of the tank body 1, the air guide bin 12 is provided with a plurality of groups, the heating box 11 is communicated with an air guide bin 12 in the tank body 1 through an air pipe 6, a conical material guide plate 14 is arranged at the bottom of the inner wall of the tank body 1, a material discharge pipe 15 is arranged at the bottom of the material guide plate 14, a material valve 16 is arranged on the material discharge pipe 15, a secondary separation material discharge pipe 17 is arranged on the side wall of the tank body 1, the secondary separation material discharge pipe 17 is positioned above the material guide plate 14, a circular material blowing pipe 18 is fixed on the inner wall of the tank body 1, the material blowing pipe 18 is provided with a material blowing air jet head I1301 and a material blowing air jet head II 1302, the air compressor 3 is provided with an air pipe.

Wherein, the top of the tank body 1 is provided with a boss 101. The boss 101 on the top of the tank body 1 is beneficial to layering of water vapor and fog drops, the layered water vapor does not contact with the fog drops again, and drying efficiency is improved. Meanwhile, the layered water vapor and the layered fog drops can reduce the possibility that the fog drops are sucked out of the tank body 1 by the suction cup 8.

Wherein, the inner diameter of the upper end of the gas guide cabin 12 is larger than that of the lower end. Design like this can guarantee that air guide chamber 12's jet-propelled head 13 can incline upwards to make from jet-propelled head 13 steam can with the abundant contact of 4 air-propelled fog form feed liquids of shower nozzle, steam and vaporific feed liquid move in opposite directions, slow down vaporific feed liquid falling speed, thereby prolong the contact time of vaporific feed liquid and steam, improve drying efficiency.

The cross section of the blowing pipe 18 is semi-cylindrical, the bottom of the blowing pipe 18 is in contact with the upper end of the guide plate 14, the blowing air nozzle I1301 is parallel to the guide plate 14, the bottom of the blowing air nozzle I1301 is in contact with the guide plate 14, and the blowing air nozzle II 1302 is vertically upward relative to the blowing air nozzle I1301. The material blowing air nozzle I1301 which is parallel to the material guide plate 14 and is in contact with the material guide plate 14 can blow the powdery particle water reducing agent falling on the material guide plate 14 to the discharge pipe 15 at the bottom, so that the material guide plate 14 cannot accumulate materials. And the material blowing air nozzle II 1302 which is vertically upward relative to the material blowing air nozzle I1301 can blow an upward oblique air flow, so that the falling speed of the water reducing agent can be reduced, the drying time of the water reducing agent is prolonged, and the drying efficiency is improved. Meanwhile, the semi-cylindrical material blowing pipe 18 is not beneficial to generating material accumulation due to the radian of the semi-cylindrical material blowing pipe.

When the air-conditioning tank is used, the exhaust fan 10 and the heating box 11 are started firstly, hot air enters the air guide bin 12 through the air pipe 6, and then enters the tank body 1 from the air nozzle 13 of the air guide bin 12. The thermometer 20 is observed and when the thermometer 20 shows that the temperature has reached the desired value, the peristaltic pump 2, the air compressor 3 and the suction fan 7 are activated. The peristaltic pump 2 pumps the water reducing agent slurry in the feed liquid tank 19 into the spray head 4, and the air compressor 3 also discharges compressed air into the spray head 4, so that the slurry is sprayed out in a spraying mode at the spray head 4. When the sprayed fog drops meet the high temperature in the tank, the water vapor in the fog drops is quickly gasified to form water vapor. The water vapor floats upwards, enters the top of the boss 101 and is sucked out by the sucker 8. The water vapor enters the dryer 9 through the exhaust fan 7, and the dryer 9 absorbs the moisture in the water vapor. And the air inlet of the exhaust fan 10 is connected with the air outlet of the dryer 9, so that the dried air with residual temperature is reused by the exhaust fan 10 and is heated again to enter the tank body 1. The exhaust gas residual heat is fully utilized, the energy is saved, and the heat efficiency is improved. And the water reducing agent particles which are dried quickly in the tank body 1 continuously fall to the bottom of the tank body 1 under the action of self gravity, and are finally discharged from the discharge pipe 15 through the material guide plate 14.

Because the air guide bin 12 is provided with the air nozzles 13 which are obliquely arranged upwards and the bottom of the tank body 1 is also provided with the air nozzles 13 which are obliquely arranged upwards, the formed granular water reducing agent can be influenced by the upward moving hot air flow and the compressed air flow in the falling process, so that the falling speed of the water reducing agent is reduced, the drying time of the water reducing agent in the tank body 1 is prolonged, and the drying efficiency is improved.
