Calcium-based dry desulfurizer is a chemical used for flue gas desulfurization. Flue gases produced in industrial processes such as coal and fuel oil often contain large amounts of sulfur dioxide, which poses a great threat to the environment and human health. Calcium-based dry desulfurizer converts it into calcium sulfate by chemical reaction with sulfur dioxide, so as to achieve the purpose of desulfurization.
Calcium-based dry desulfurizer is mainly composed of calcium oxide and additives. Calcium oxide is the main desulfurizer, which has a high alkalinity and activity, and can fully react with sulfur dioxide. The additives can improve the desulfurization efficiency and stability of calcium oxide and prolong the service life of the desulfurizer. Commonly used additives are sodium sulfide, ammonium sulfide, etc.
Twin Screw Pelletizing Machine Twin Screw Pelletizing Machine, it has the following advantages:
1) The meshing tooth shape of the twin screw is:"v"Glyphs, which are characterized by:
After the material enters the meshing area, the gap between the two teeth is constantly changed with the continuous addition and discharge of the material, so as to realize the continuous feeding and discharging process.
2) The axial force of the twin screw is small and the radial force is large.
3) Since the material is forced into the meshing zone, it has less shearing effect.
4) When the material passes, there is no relative sliding between the two teeth.
5) Because the frictional resistance between the two spirals is small and there is no self-locking (that is, it cannot be automatically maintained in the original position), it has strong adaptability to the material.
6) Low noise and light vibration during work.
7) Simple and compact structure, light weight, easy installation and other advantages. The twin-screw granulator is suitable for the processing, forming and drying of various powdery materials.
The particles made by this machine are hard extruded by the screw rod and steel plate, the particles have a regular shape, compact texture, less fine powder, and are not easy to absorb moisture. Since the granulation process of powdered materials is completed in the wet state, the operating conditions of granulation and its subsequent processes (such as drying, packaging, etc.) are greatly improved. Generally, it can reduce the dust flying on site by more than 90%. Through granulation, it can avoid the phenomenon of agglomeration, bridging, pulsation and other phenomena that affect the use of powder products, and at the same time avoid the secondary pollution caused by powder in the use process, so that the physical properties of the product can be greatly improved. In general, the proportion of granulated products is greatly increased, so it can save transportation, storage and packaging space. For multi-component compounding and mixed products, granulation can avoid the segregation of each component, so as to truly ensure the quality of composite products.
The twin-screw extruder feeding method is a forced feeding method that relies on the gap extrusion of two screws;The material passes through the feeding port, under the action of the rotating screw, is rolled into a ball and rolls along the screw groove, due to the shearing, compression and stirring of the screw, the material is further mixed, and passes through the machine head at a certain pressure and temperature to obtain the product of the required shape.
