The utility model discloses a device has following advantage with current cooling device contrast: 1. the process index is stable, and the product can be effectively prevented from absorbing moisture in the cooling process; 2. the dust leakage is controlled to the maximum extent, and the production environment is improved; 3. energy consumption and equipment installation space can be greatly saved.
Description
Technical Field
The utility model relates to a chemical product cooling especially relates to the cooling of chemical industry powder material, further relates to a dry finished product cooling device of wet process phosphoric acid production monocalcium phosphate.
Background
In the process of producing calcium dihydrogen phosphate by wet-process phosphoric acid, most of moisture is removed from calcium dihydrogen phosphate slurry through drying, and the dried finished product is cooled and cooled to further remove moisture and heat, so that the packaging performance requirement of the product is met. When the dried calcium dihydrogen phosphate finished product is cooled, the traditional cooling method is easy to bring moisture in natural air, the hygroscopicity of the calcium dihydrogen phosphate product is strong, and the moisture absorption is very easy in the cooling process; in addition, the traditional cooling device has large occupied area and large sealing difficulty, and dust is easy to leak to cause pollution. A reasonable drying finished product cooling device is selected to isolate natural air, so that the material cooling process is effectively sealed to prevent moisture absorption and dust leakage, energy can be comprehensively saved, and space can be saved, and the device is very important.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a dry finished product cooling device of wet process phosphoric acid production monocalcium phosphate to the cooling effectively avoids the product moisture absorption to product quality and production environment's influence in the reduction monocalcium phosphate production, guarantees product quality.
The technical scheme of the utility model: a cooling device for a dry finished product of calcium dihydrogen phosphate produced by wet-process phosphoric acid, in particular to a cooling device for a dry finished product of calcium dihydrogen phosphate produced by wet-process phosphoric acid. It is characterized in that the utility model mainly comprises a Roots blower, a dehumidifier, a cooler and a water cooling tower; the roots blower is connected with the dehumidifier through a pipeline, the dehumidifier is connected with the cooler through a pipeline, and the cooler is connected with the cooling tower through a pipeline and a circulating pump; the cooler consists of a feeding bin, a heat transfer plate group and a discharging hopper.
The feed inlet of the cooler is arranged at the top of the cooler, and the discharge outlet is arranged at the bottom of the cooler.
The lower part of the cooler is provided with a circulating water inlet, and the upper part of the cooler is provided with a circulating water outlet.
And an exhaust port of the cooler is arranged at the top.
The cooler is also provided with a level indicator.
The principle and the using method of the utility model are as follows: the powder flow heat exchanger is used as a cooling process carrier, low-temperature clean circulating water and cold dry air are used as refrigerants to cool the dried finished product, the circulating water is recycled, the cooling process is carried out in the totally-closed powder flow cooler, the material liquid level of the cooler is controlled through automatic linkage, the cooling process of the dried finished product of the monocalcium phosphate is ensured to be in steady-state operation, and the moisture absorption and dust leakage of the product in the cooling process are reduced to the minimum. When the cleaning circulating water is used, the temperature of the cleaning circulating water is controlled to be 20-30 ℃. The temperature of the cold dry air is controlled to be 25-30 ℃. The material liquid level of the cooler is controlled to be 20% -80%.
The utility model has the advantages of it is following: 1, the process index is stable, and the product can be effectively prevented from absorbing moisture in the cooling process; 2, controlling dust leakage to the maximum extent and improving production environment; 3, energy consumption and equipment installation space can be greatly saved.
