Description

Technical field:

[0001] The utility model relates to the technical field of lime kiln equipment, in particular to a novel environmentally friendly lime kiln. Background technology:

[0002] Different forms of lime kilns have different structures and calcination forms. The process flow is basically the same, but the equipment value is very different. Of course, the use effect is definitely different. Calcining quicklime has a long history in my country. Up to now, the amount of ash used in metallurgy, chemical industry, and building materials industries has increased, and the requirements for lime quality have become higher and higher. However, there are still a large number of low-cost ordinary vertical kilns used for quicklime production in my country.

[0003] For example, an environmentally friendly lime kiln with the authorization announcement number "CN212800174U" can reduce material waste and better meet usage needs. However, when the lime is calcined in this environmentally friendly lime kiln, a large amount of waste gas will be generated. These waste gases are directly discharged without being treated, which pollutes the surrounding environment and reduces the working quality of the lime kiln. At the same time, this environmentally friendly lime kiln requires the operator to step on the pedal to drive the operator to rise, but the overall weight of the lifting equipment is too large, requiring the operator to exert a lot of force, which increases the workload of the operator.
