1. Dehumidification of complete set of organic fertilizer equipment: the critical relative humidity of water to fertilizer (higher than this humidity, the fertilizer will naturally absorb water) is very low, or more easily hygroscopic compounds are formed, which makes water soluble fertilizer rapidly and completely dissolved in water, but also easily leads to moisture absorption and agglomeration of water soluble fertilizer in the production process, poor liquidity, and subsequent processes can not be carried out normally. Therefore, attention should be paid to dehumidification in the production process of water-soluble fertilizer. Common dehumidification methods include freezing dehumidification, hot air dehumidification and adsorption dehumidification. Refrigeration dehumidification is to reduce the air temperature to below the dew point, so that the water vapor in the air can condense and separate out for dehumidification. It mainly has the disadvantages of complex equipment structure, large power consumption, compressor use of Freon, etc., and it is difficult to meet the requirements of low humidity dehumidification due to the influence of the temperature of the cooling medium; The hot air dehumidification is to reduce the relative humidity by heating the air, and to reduce the relative humidity by controlling the temperature, which can not really reduce the content of water swallow in the air, and it is difficult to ensure the dehumidification effect; Adsorption dehumidification refers to the dynamic adsorption of water vapor in the air by adsorption materials, which can be divided into wet liquid absorption dehumidification and solid adsorption dehumidification. Among them, solid adsorbent is the core component of rotary adsorption dehumidification! It is characterized by high dehumidification efficiency, continuous operation, controllable humidity, compact structure, energy saving and material saving.

2. Dust removal of complete set of organic fertilizer equipment: water-soluble fertilizer is powdery material, which is easy to form dust during production. Dust easily pollutes the environment and affects people's health. People who inhale too much dust for a long time will cause inflammation of the mucous membranes of the nose, throat, eyes, trachea and bronchi. The finer the dust is, the longer it stays in the air, the more chances it has to be inhaled, and the more obvious the fibrogenic effect on the lung tissue. It is the direct cause of pneumoconiosis, silicosis and other diseases. Dust can also accelerate the wear of machinery and affect the life of mechanical equipment. Dust falling on electrical equipment may damage insulation or hinder heat dissipation, which is easy to cause accidents. The dust discharged outside the plant will pollute the atmosphere around the plant and affect the environmental health.

If conditions (dust concentration, temperature, ignition source, etc.) are available, combustion or explosion accidents may occur, which is very destructive. The United States is a country with relatively complete processing equipment, and dust explosion accidents in American factories are common. Explosion accidents often occur in fertilizer plants and warehouses in China, especially in water-soluble fertilizer manufacturers. Therefore, special dedusting equipment should be added during the production of water-soluble fertilizer.
