Problems solved by technology

Traditional vibrating fluidized bed dryers are used to dry polyacrylamide by drying medium. The dried polyacrylamide particles are directly transported with the drying medium gas. The subsequent pulverization of polyacrylamide particles still needs to be cooled, and the drying medium is directly discharged, which wastes heat energy. , not conducive to energy saving and emission reduction

The polyacrylamide dryer is characterized by comprising a first air inlet tube, a first air inlet fan, a first natural gas burner, a first dryer body, a second air inlet tube, a second air inlet fan, a second natural gas burner, a second dryer body and an air return tube, wherein the first air inlet fan and the first natural gas burner are sequentially arranged on the first air inlet tube, the first air inlet tube is communicated with the first dryer body for air intake, the second air inlet fan and the second natural gas burner are arranged on the second air inlet tube, the second air inlet tube is communicated with the second dryer body for air intake, the second dryer body is connected with the first air inlet tube through the air return tube for air return, and the first dryer body is connected with the second dryer body for discharging. Feeding augers are arranged in the first dryer body and the second dryer body and comprise rotating shafts and blade groups.

Description

technical field [0001] The invention relates to a drying device, in particular to a polyacrylamide dryer. Background technique [0002] The production of polyacrylamide is based on the aqueous solution of acrylamide as the raw material, under the action of the initiator, the polymerization reaction is carried out, and the polyacrylamide rubber blocks formed after the reaction are cut, granulated, dried and crushed, and finally the polyacrylamide product is obtained . The drying of polyacrylamide not only needs to evaporate a large amount of water, but also controls the temperature of the material not to be too high, and at the same time prevents local overheating, so the high efficiency and energy saving of the dryer are particularly prominent. Traditional vibrating fluidized bed dryers are used to dry polyacrylamide by drying medium. The dried polyacrylamide particles are directly transported with the drying medium gas. The subsequent pulverization of polyacrylamide partic...
