Environmentally friendly vertical lime kiln

In today's era of pursuing environmental protection and efficient industrial production, the environmentally friendly lime kiln vertical kiln has become a shining star in the field of lime production with its unique structural design, advanced equipment composition, and excellent production capacity.

1、 Structure of environmentally friendly vertical lime kiln

The structure design of the environmentally friendly vertical lime kiln is exquisite, aiming to achieve efficient heat transfer and material processing.

Kiln body

The kiln body is the core part of the entire vertical kiln, usually made of high-temperature and corrosion-resistant materials to withstand the harsh environment during high-temperature calcination. It is equipped with multiple layers of refractory bricks inside, which effectively insulate and reduce heat loss.

Feeding system

The feeding system is located at the top of the kiln and uses advanced quantitative feeding equipment to ensure that the raw materials enter the kiln evenly and stably. For example, using a screw conveyor or belt conveyor can accurately control the feeding speed and quantity.

Discharge system

There is a discharge device at the bottom of the kiln body, and the lime that has been calcined is promptly discharged through this system. Common discharge methods include gravity discharge and mechanical discharge to meet the needs of different production scales. combustion system

The combustion system is a critical component that provides thermal energy. Adopting advanced burners can achieve efficient combustion of fuel and reduce pollutant emissions. At the same time, through reasonable air duct design, ensure sufficient oxygen supply for combustion.

2、 Equipment composition

The environmental protection lime kiln vertical kiln equipment consists of multiple important parts, each performing its own duties and working together to achieve efficient and environmentally friendly lime production.

The feeding equipment is responsible for accurately and stably transporting raw materials into the kiln. Advanced belt conveyors or bucket elevators are usually used, which can accurately control the feeding speed and quantity, ensuring the continuity of production. The role of fabric equipment is crucial, as it evenly distributes the raw materials entering the kiln, making the calcination process more uniform and thorough. Common fabric methods include rotating fabric and bell shaped fabric, which effectively avoid the accumulation or uneven distribution of raw materials.

The calcination equipment is the core part, which provides suitable temperature and environment for the calcination of lime through advanced combustion system and reasonable kiln structure. Efficient burners can fully utilize energy, improve calcination efficiency, and reduce pollutant emissions.

The ash unloading equipment smoothly discharges the finished lime from the kiln after calcination is completed. Star shaped ash discharge valves and scraper conveyors are commonly used ash discharge equipment, which can stably discharge materials, ensure orderly production, and reduce dust leakage, meeting environmental protection requirements.

These devices work together to form an efficient production system for environmentally friendly vertical lime kilns.

3、 Capacity scale

The production capacity and scale of environmentally friendly vertical lime kilns vary depending on their specifications and configurations.

Generally speaking, the daily output of small-scale environmentally friendly vertical lime kilns can reach tens of tons, medium-sized ones can reach several hundred tons, and large-scale ones can reach thousands of tons.

For example, a certain model of vertical kiln has a diameter of 3-6 meters and a height of 30-39 meters. It adopts advanced combustion and control technology, and its daily output can reach 500 tons, which can meet the needs of medium-sized lime production enterprises. In actual production, production capacity is also affected by various factors such as raw material quality, operational level, and equipment maintenance. By optimizing process parameters and improving operational management, the production capacity potential of vertical kilns can be further explored.
