Abstract

The invention discloses a production method of monopotassium phosphate. A production device comprises a feed calcium slurry tank (1), a reaction tank (2), a feed calcium slurry pump (3), a reaction slurry pump (4), a first automatic back washing surface filter (5), a primary evaporator (6), an impurity removal and desulfurization tank (7), a second automatic back washing surface filter (8), a slurry pump (9), a secondary evaporator (10), a mother solution pump (11), a crystallizer (12), a crystal mush pump (13), a flat plate scraper centrifuge (14), a drier (15), a methanol delivery pump (16), a methanol recovery storage tank (17) and a methanol condenser (18). With the adoption of the production device and a production technology flow, feed calcium hydrophosphate and potassium hydrogen sulfate generate replacement reaction, so that the content of a produced product can reach 98%, the cost is greatly lower than the production cost of a product obtained by a neutralization method production technology, and the production method is simple in technology and extensive in raw material source, and has broad market application prospects.

Description

technical field [0001] The invention relates to a production technology of chemical fertilizers, in particular to a production method of potassium dihydrogen phosphate. Background technique [0002] Potassium dihydrogen phosphate is a high-efficiency phosphorus and potassium fertilizer. It has a wide range of applications and a large demand. The market price is about 4 times that of a single potassium chloride potassium fertilizer. The utilization rate of potassium dihydrogen phosphate can almost reach 100%. The double effect of potassium fertilizer has a good effect on increasing production, and the application of potassium dihydrogen phosphate can get more output with less input. Although my country is a big country in the production and consumption of potassium dihydrogen phosphate, in the past, there were mainly single factories, and the production technology of neutralization method with high cost was adopted, and the production technology was still relatively backward....
