Description

A high-efficiency dust removal device for cement production

Technical Field

The invention relates to the technical field of cement production, in particular to a high-efficiency dust removal device for cement production.

Background Art

Cement, also known as cement, red lime, red soil, etc., is a powdery hydraulic inorganic gelling material that will solidify and harden after mixing with water. It is usually not used alone, but used to combine with sand and gravel to form mortar or concrete. The main raw materials of cement are lime or calcium silicate. After hardening, it can resist the erosion of fresh water or salt water. As an important gelling material, it is widely used in civil construction, water conservancy, national defense and other projects.

Limestone, clay and iron ore powder are ground and mixed in proportion to form raw materials, which are then calcined. The calcined product is called clinker, which is then ground and mixed with gypsum in proportion to form cement.

There are multiple mixing processes in the cement production process. Since the ground molecular materials are mixed, a large amount of dust will be generated during the mixing process. The dust treatment devices commonly used in existing cement production mostly use plate-type anode plates for electrostatic dust removal. As the length of the anode plate changes, an increasing number of anode wires will be placed between the two anode plates. However, the effective electrostatic triggering area between each anode wire and the anode plate is small. The anode wires need to be arranged more closely to maximize the use of the anode plate, which will increase the production cost and use cost. In addition, the anode plate of the existing dust treatment device only has a shaking function, and it is a bottom contact shaking. The lower part of the anode plate shakes more, and the upper part shakes less. There will be dust residue on the upper part, which is not conducive to efficient dust removal. At the same time, relying solely on shaking, the dust cleaning of the anode plate is not thorough enough, which will affect the subsequent adsorption effect.
