Rotary kiln drying method

Abstract

The invention discloses a rotary kiln drying method, belongs to the technical field of metallurgy, and provides a rotary kiln drying method capable of improving the kiln drying efficiency. According to the kiln drying method, clinker is guided into a rotary kiln in the kiln drying process, thus, by means of heat conduction, temperature transmitting and other effects of the clinker, the temperaturetransmitting and distribution effect of the interior of the rotary kiln are effectively improved, accordingly, the temperature rising speed of the interior of the rotary kiln is increased, temperature fluctuation is reduced, the temperature distribution uniformity of the interior of the rotary kiln is improved, the kiln drying quality can be improved, the kiln drying time can be shortened, and the kiln drying cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a method for drying a rotary kiln. Background technique [0002] The rotary kiln can only be put into normal use after the kiln is newly built or repaired after bricklaying. The current kiln drying methods are all empty kiln drying kilns, and the empty kiln drying kiln method has the problem of slow dehydration, resulting in generally longer drying time; especially for large rotary kilns, because of the large space and long length of the rotary kiln Insufficient dehydration of the rotary kiln, poor penetration effect of the kiln, unstable temperature of the kiln, etc., will seriously affect the quality of the kiln, resulting in frequent brick drop and kiln collapse during the production process, increasing the auxiliary production equipment The cost of materials seriously restricts production indicators. Moreover, it takes a long time to dry the kiln with an empty kiln, whic...

Problems solved by technology

The current kiln drying methods are all empty kiln drying kilns, and the empty kiln drying kiln method has the problem of slow dehydration, resulting in generally longer drying time; especially for large rotary kilns, because of the large space and long length of the rotary kiln Insufficient dehydration of the rotary kiln, poor penetration effect of the kiln, unstable temperature of the kiln, etc., will seriously affect the quality of the kiln, resulting in frequent brick drop and kiln collapse during the production process, increasing the auxiliary production equipment The cost of materials seriously restricts the production index

Moreover, it takes a long time to dry the kiln with an empty kiln, which will affect the production, increase the energy consumption of the kiln, waste resources and increase the cost

To sum up, it can be seen that the traditional empty kiln drying method has problems such as poor quality, long time and high cost, resulting in very low drying efficiency; especially for large-scale rotary kiln drying, the above problems are more prominent
