The continuous crystallization process is stable in operation, low in energy consumption and low in labor intensity; and by using the continuous crystallization process, the operation stability and the product quality are greatly improved, the on-site operation environment is improved, and the production cost of the monopotassium phosphate is reduced. A mating device for the process is small in floor area and high in capacity.

Self-cleaning fluidized bed heat exchanger
ActiveCN107764109BGood heat transfer coefficientFlush cleaningFluidised bed heat exchangersSolid particleEngineering
The invention relates to a self-cleaning fluidized bed heat exchanger which is mainly used for solving the technical problems that in the prior art, the tube pass of a decarburization alkaline liquorcooler of an ammonia synthesizing device is prone to scaling, and the heat exchange effect is obviously decreased after long-period use. The self-cleaning fluidized bed heat exchanger comprises a lower tube box 1, a heat exchanger tube nest 2, an upper tube box 3, a liquid-solid separator 4, a particle filtering plate 5, a liquid storing tank 6, a liquid circulating pump 7, a downcomer 8, a spraynozzle 9, a horizontal pipe 10 and an expanding port 11, wherein the expanding port 11 is installed in the lower tube box 1, the upper tube box 3 is connected with the liquid-solid separator 4, solidparticles enter the spray nozzle 9 through the downcomer 8, and a liquid phase overflows from the upper portion of the particle filtering plate 5, enters the liquid storing tank 6 and circulates to the spray nozzle 9 through the liquid circulating pump 7. According to the technical scheme, the technical problems are well solved, and the self-cleaning fluidized bed heat exchanger can be used for prolonging the running cycle of the decarburization alkaline liquor cooler of the ammonia synthesizing device.
