For solving the problems of the technologies described above, the polyacrylamide particle drying device that the utility model provides, comprise fluid bed with material chamber, described fluid bed also is provided with charging aperture, discharging opening, air inlet and air outlet, described charging aperture and discharging opening lay respectively at the two ends, the left and right sides of fluid bed and communicate with the material chamber, described air inlet is positioned under the material chamber, air outlet communicates with the material chamber, described material chamber is divided into high-temperature region and the middle warm area that communicates by baffle plate along its length, described charging aperture communicates with the high-temperature region, and described discharging opening communicates with middle warm area; Described high-temperature region and middle warm area are respectively equipped with high-temperature region air inlet, high-temperature region air outlet and middle warm area air inlet, middle warm area air outlet, and described middle warm area air outlet communicates with the high-temperature region air inlet in the fluid bed outside.
Described high-temperature region and middle warm area communicate and are meant, have the gap between described baffle plate lower end and the material bottom surface, chamber.
The air intake place of described high-temperature region air inlet and middle warm area air inlet is equipped with heater, and each heater is formed by preheater and heater, and the exhaust outlet of preheater communicates with the air inlet of heater; The warm area air outlet communicates by the air inlet of pipeline with the heater at high-temperature region air intake place in described.
Warm area air outlet place is connected with cyclone dust collectors in described.
Air outlet place, described high-temperature region is connected with cyclone dust collectors and sack cleaner in turn.
The material chamber lower floor of described fluid bed also is provided with cooling air inlet, and described cooling air inlet is between middle warm area air inlet and discharging opening.
After adopting above structure, the utility model compared with prior art has the following advantages:
1) because the utility model will expect that the chamber is divided into high-temperature region and two arid regions of middle warm area, and middle warm area air outlet communicates with the high-temperature region air inlet, circulation flowed into the high-temperature region air inlet after the vapours that has moisture content that warm area air outlet place produces was like this discharged fluid bed, realized making full use of of heat energy, improved production capacity greatly, cut down the consumption of energy;
2) avoid making polyacrylamide polymers to be in the hot environment for a long time, micromolecular polymer occurs being cracked between the polymer molecule or be cross-linked into the more probability of the polymer of macromolecule thereby reduce, the polyacrylamide particle quality of producing like this is better;
3) in addition, also be provided with cooling air inlet before discharging opening, the polyacrylamide particle rapid heat dissipation that drying is finished does not need heat-resisting container that a polyacrylamide material of heat is contained in the place or equipment of air cooling yet, therefore simplify production process greatly, enhance productivity;
4) not bad, the waste gas of discharging from the high-temperature region air outlet of fluid bed, by just entering in the atmosphere after cyclone dust collectors and the sack cleaner, the hot gas that middle warm area air outlet is discharged significantly reduces the pollution of atmospheric environment also by just entering the high-temperature region air inlet behind the cyclone dust collectors.
